IPTables masquerading with one NIC

- by Tuinslak

Hi, I am running an OpenVPN server with only one NIC. This is my current layout: public.ip > Cisco firewall > lan.ip > OpenVPN server lan.ip = 192.168.22.70 The Cisco firewall forwards the requests to the oVPN server, thus so far everything works and clients are able to connect. However, all clients connected should be able to access 3 networks: lan1: 192.168.200.0 (vpn lan) > tun0 lan2: 192.168.110.0 (office lan) > eth1 (gw 192.168.22.1) lan3: 192.168.22.0 (server lan) > eth1 (broadcast network) So tun0 is mapped to eth1. Iptables output: # iptables-save # Generated by iptables-save v1.4.2 on Wed Feb 16 14:14:20 2011 *filter :INPUT ACCEPT [327:26098] :FORWARD DROP [305:31700] :OUTPUT ACCEPT [291:27378] -A INPUT -i lo -j ACCEPT -A INPUT -i tun0 -j ACCEPT -A INPUT -i ! tun0 -p udp -m udp --dport 67 -j REJECT --reject-with icmp-port-unreachable -A INPUT -i ! tun0 -p udp -m udp --dport 53 -j REJECT --reject-with icmp-port-unreachable -A FORWARD -d 192.168.200.0/24 -i tun0 -j DROP -A FORWARD -s 192.168.200.0/24 -i tun0 -j ACCEPT -A FORWARD -d 192.168.200.0/24 -i eth1 -j ACCEPT COMMIT # Completed on Wed Feb 16 14:14:20 2011 # Generated by iptables-save v1.4.2 on Wed Feb 16 14:14:20 2011 *nat :PREROUTING ACCEPT [302:26000] :POSTROUTING ACCEPT [3:377] :OUTPUT ACCEPT [49:3885] -A POSTROUTING -o eth1 -j MASQUERADE COMMIT # Completed on Wed Feb 16 14:14:20 2011 Yet, clients are unable to ping any ip (including 192.168.200.1, which is the oVPN's IP) When the machine was directly connected to the internet, with 2 NICs, it was quite simply solved with masquerading and adding static routes in the oVPN client's config. However, as masquerading won't accept virtual interfaces (eth0:0, etc) I am unable to get masquerading to work again (and I'm not even sure whether I need virtual interfaces). Thanks.

VFP Unit Matrix Multiply problem on the iPhone

- by Ian Copland

Hi. I'm trying to write a Matrix3x3 multiply using the Vector Floating Point on the iPhone, however i'm encountering some problems. This is my first attempt at writing any ARM assembly, so it could be a faily simple solution that i'm not seeing. I've currently got a small application running using a maths library that i've written. I'm investigating into the benifits using the Vector Floating Point Unit would provide so i've taken my matrix multiply and converted it to asm. Previously the application would run without a problem, however now my objects will all randomly disappear. This seems to be caused by the results from my matrix multiply becoming NAN at some point. Heres the code IMatrix3x3 operator*(IMatrix3x3 & _A, IMatrix3x3 & _B) { IMatrix3x3 C; //C++ code for the simulator #if TARGET_IPHONE_SIMULATOR == true C.A0 = _A.A0 * _B.A0 + _A.A1 * _B.B0 + _A.A2 * _B.C0; C.A1 = _A.A0 * _B.A1 + _A.A1 * _B.B1 + _A.A2 * _B.C1; C.A2 = _A.A0 * _B.A2 + _A.A1 * _B.B2 + _A.A2 * _B.C2; C.B0 = _A.B0 * _B.A0 + _A.B1 * _B.B0 + _A.B2 * _B.C0; C.B1 = _A.B0 * _B.A1 + _A.B1 * _B.B1 + _A.B2 * _B.C1; C.B2 = _A.B0 * _B.A2 + _A.B1 * _B.B2 + _A.B2 * _B.C2; C.C0 = _A.C0 * _B.A0 + _A.C1 * _B.B0 + _A.C2 * _B.C0; C.C1 = _A.C0 * _B.A1 + _A.C1 * _B.B1 + _A.C2 * _B.C1; C.C2 = _A.C0 * _B.A2 + _A.C1 * _B.B2 + _A.C2 * _B.C2; //VPU ARM asm for the device #else //create a pointer to the Matrices IMatrix3x3 * pA = &_A; IMatrix3x3 * pB = &_B; IMatrix3x3 * pC = &C; //asm code asm volatile( //turn on a vector depth of 3 "fmrx r0, fpscr \n\t" "bic r0, r0, #0x00370000 \n\t" "orr r0, r0, #0x00020000 \n\t" "fmxr fpscr, r0 \n\t" //load matrix B into the vector bank "fldmias %1, {s8-s16} \n\t" //load the first row of A into the scalar bank "fldmias %0!, {s0-s2} \n\t" //calulate C.A0, C.A1 and C.A2 "fmuls s17, s8, s0 \n\t" "fmacs s17, s11, s1 \n\t" "fmacs s17, s14, s2 \n\t" //save this into the output "fstmias %2!, {s17-s19} \n\t" //load the second row of A into the scalar bank "fldmias %0!, {s0-s2} \n\t" //calulate C.B0, C.B1 and C.B2 "fmuls s17, s8, s0 \n\t" "fmacs s17, s11, s1 \n\t" "fmacs s17, s14, s2 \n\t" //save this into the output "fstmias %2!, {s17-s19} \n\t" //load the third row of A into the scalar bank "fldmias %0!, {s0-s2} \n\t" //calulate C.C0, C.C1 and C.C2 "fmuls s17, s8, s0 \n\t" "fmacs s17, s11, s1 \n\t" "fmacs s17, s14, s2 \n\t" //save this into the output "fstmias %2!, {s17-s19} \n\t" //set the vector depth back to 1 "fmrx r0, fpscr \n\t" "bic r0, r0, #0x00370000 \n\t" "orr r0, r0, #0x00000000 \n\t" "fmxr fpscr, r0 \n\t" //pass the inputs and set the clobber list : "+r"(pA), "+r"(pB), "+r" (pC) : :"cc", "memory","s0", "s1", "s2", "s8", "s9", "s10", "s11", "s12", "s13", "s14", "s15", "s16", "s17", "s18", "s19" ); #endif return C; } As far as i can see that makes sence. While debugging i've managed to notice that if i were to say _A = C prior to the return and after the ASM, _A will not necessarily be equal to C which has only increased my confusion. I had thought it was possibly due to the pointers I'm giving to the VFPU being incrimented by lines such as "fldmias %0!, {s0-s2} \n\t" however my understanding of asm is not good enough to properly understand the problem, nor to see an alternative approach to that line of code. Anyway, I was hoping someone with a greater understanding than me would be able to see a solution, and any help would be greatly appreciated, thank you :-)

ASP.NET MVC 2 - Saving child entities on form submit

- by Justin

Hey, I'm using ASP.NET MVC 2 and am struggling with saving child entities. I have an existing Invoice entity (which I create on a separate form) and then I have a LogHours view that I'd like to use to save InvoiceLog's, which are child entities of Invoice. Here's the view: <%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage<TothSolutions.Data.Invoice>" %> <asp:Content ID="Content1" ContentPlaceHolderID="TitleContent" runat="server"> Log Hours </asp:Content> <asp:Content ID="Content3" ContentPlaceHolderID="HeadContent" runat="server"> <script type="text/javascript"> $(document).ready(function () { $("#InvoiceLogs_0__Description").focus(); }); </script> </asp:Content> <asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server"> <h2>Log Hours</h2> <% using (Html.BeginForm("SaveHours", "Invoices")) {%> <%: Html.ValidationSummary(true) %> <fieldset> <legend>Fields</legend> <table> <tr> <th>Date</th> <th>Description</th> <th>Hours</th> </tr> <% int index = 0; foreach (var log in Model.InvoiceLogs) { %> <tr> <td><%: log.LogDate.ToShortDateString() %></td> <td><%: Html.TextBox("InvoiceLogs[" + index + "].Description")%></td> <td><%: Html.TextBox("InvoiceLogs[" + index + "].Hours")%></td> <td>Hours</td> </tr> <% index++; } %> </table> <p> <%: Html.Hidden("InvoiceID") %> <%: Html.Hidden("CreateDate") %> <input type="submit" value="Save" /> </p> </fieldset> <% } %> <div> <%: Html.ActionLink("Back to List", "Index") %> </div> </asp:Content> And here's the controller code: //GET: /Secure/Invoices/LogHours/ public ActionResult LogHours(int id) { var invoice = DataContext.InvoiceData.Get(id); if (invoice == null) { throw new Exception("Invoice not found with id: " + id); } return View(invoice); } //POST: /Secure/Invoices/SaveHours/ [AcceptVerbs(HttpVerbs.Post)] public ActionResult SaveHours([Bind(Exclude = "InvoiceLogs")]Invoice invoice) { TryUpdateModel(invoice.InvoiceLogs, "InvoiceLogs"); invoice.UpdateDate = DateTime.Now; invoice.DeveloperID = DeveloperID; //attaching existing invoice. DataContext.InvoiceData.Attach(invoice); //save changes. DataContext.SaveChanges(); //redirect to invoice list. return RedirectToAction("Index"); } And the data access code: public static void Attach(Invoice invoice) { var i = new Invoice { InvoiceID = invoice.InvoiceID }; db.Invoices.Attach(i); db.Invoices.ApplyCurrentValues(invoice); } In the SaveHours action, it properly sets the values of the InvoiceLog entities after I call TryUpdateModel but when it does SaveChanges it doesn't update the database with the new values. Also, if you manually update the values of the InvoiceLog entries in the database and then go to this page it doesn't populate the textboxes so it's clearly not binding correctly. Thanks, Justin

Using dispatchertimer in combination with an asynchroneous call

- by Civelle

Hi. We have an issue in our Silverlight application which uses WCF and Entity Framework, where we need to trap the event whenever a user shuts down the application by closing the web page or the browser instead of closing the silverlight application. This is in order to verify if any changes have been made, in which case we would ask the user if he wants to save before leaving. We were able to accomplish the part which consists in trapping the closing of the web page: we wrote some code in the application object that have the web page call a method in the silverlight application object. The problem starts when in this method, we do an asynchroneous call to the Web Service to verify if changes have occured (IsDirty). We are using a DispatcherTimer to check for the return of the asynchroneous call. The problem is that the asynchroneous call never completes (in debug mode, it never ends up stepping into the _BfrServ_Customer_IsDirtyCompleted method), while it used to work fine before we added this new functionality. You will find belowthe code we are using. I am new to writing timers in combination with asynchroneous call so I may be doing something wrong but I cannot figure out what. I tried other things also but we without any success.. ====================== CODE ============================================== 'Code in the application object Public Sub New() InitializeComponent() RegisterOnBeforeUnload() _DispatcherTimer.Interval = New TimeSpan(0, 0, 0, 0, 500) End Sub Public Sub RegisterOnBeforeUnload() 'Register Silverlight object for availability in Javascript.

How do I load an image from sd card into coverview

- by Jolene

I am doing an application which consists of a cover flow. Currently I am trying to make the cover flow images be obtained from the sd card. But I am not exactly sure how should I display the image. this is the image adapter: public class ImageAdapter extends BaseAdapter { int mGalleryItemBackground; private Context mContext; private FileInputStream fis; private Integer[] mImageIds = { //Instead of using r.drawable, i need to load the images from my sd card instead R.drawable.futsing, R.drawable.futsing2 }; private ImageView[] mImages; public ImageAdapter(Context c) { mContext = c; mImages = new ImageView[mImageIds.length]; } public int getCount() { return mImageIds.length; } public Object getItem(int position) { return position; } public long getItemId(int position) { return position; } @TargetApi(8) public View getView(int position, View convertView, ViewGroup parent) { int screenSize = getResources().getConfiguration().screenLayout & Configuration.SCREENLAYOUT_SIZE_MASK; ImageView i = new ImageView(mContext); i.setImageResource(mImageIds[position]); switch(screenSize) { case Configuration.SCREENLAYOUT_SIZE_XLARGE: //Toast.makeText(this, "Small screen",Toast.LENGTH_LONG).show(); Display display4 = ((WindowManager) context.getSystemService(Context.WINDOW_SERVICE)).getDefaultDisplay(); int rotation4 = display4.getRotation(); Log.d("XLarge:",String.valueOf(rotation4)); /** LANDSCAPE **/ if(rotation4 == 0 || rotation4 == 2) { i.setLayoutParams(new CoverFlow.LayoutParams(300, 300)); i.setScaleType(ImageView.ScaleType.CENTER_INSIDE); BitmapDrawable drawable = (BitmapDrawable) i.getDrawable(); drawable.setAntiAlias(true); return i; } /** PORTRAIT **/ else if (rotation4 == 1 || rotation4 == 3) { i.setLayoutParams(new CoverFlow.LayoutParams(650, 650)); i.setScaleType(ImageView.ScaleType.CENTER_INSIDE); BitmapDrawable drawable = (BitmapDrawable) i.getDrawable(); drawable.setAntiAlias(true); return i; } break; default: } return null; } /** Returns the size (0.0f to 1.0f) of the views * depending on the 'offset' to the center. */ public float getScale(boolean focused, int offset) { /* Formula: 1 / (2 ^ offset) */ return Math.max(0, 1.0f / (float)Math.pow(2, Math.abs(offset))); } } and this is how i download and save the file. I need to use the image saved and upload it into my coverflow // IF METHOD TO DOWNLOAD IMAGE void downloadFile() { new Thread(new Runnable(){ // RUN IN BACKGROUND THREAD TO AVOID FREEZING OF UI public void run(){ Bitmap bmImg; URL myFileUrl = null; try { //for (int i = 0; i < urlList.size(); i ++) //{ //url = urlList.get(i); myFileUrl = new URL("http://static.adzerk.net/Advertisers/d18eea9d28f3490b8dcbfa9e38f8336e.jpg"); // RETRIEVE IMAGE URL //} } catch (MalformedURLException e) { e.printStackTrace(); } try { HttpURLConnection conn = (HttpURLConnection) myFileUrl.openConnection(); conn.setDoInput(true); conn.connect(); InputStream in = conn.getInputStream(); Log.i("im connected", "Download"); bmImg = BitmapFactory.decodeStream(in); saveFile(bmImg); } catch (IOException e) { e.printStackTrace(); }} }).start(); // START THREAD } // SAVE THE IMAGE AS JPG FILE private void saveFile(Bitmap bmImg) { File filename; try { // GET EXTERNAL STORAGE, SAVE FILE THERE File storagePath = new File(Environment.getExternalStorageDirectory(),"Covers"); storagePath.mkdirs(); filename = new File(storagePath + "/image.jpg"); FileOutputStream out = new FileOutputStream(filename); bmImg.compress(Bitmap.CompressFormat.JPEG, 90, out); out.flush(); out.close(); MediaStore.Images.Media.insertImage(getContentResolver(),filename.getAbsolutePath(), filename.getName(), filename.getName()); // ONCE THE DOWNLOAD FINISHES, CLOSE DIALOG Toast.makeText(getApplicationContext(), "Image Saved!", Toast.LENGTH_SHORT).show(); } catch (Exception e) { e.printStackTrace(); } }

Marking multi-level nested forms as "dirty" in Rails

- by Charles Kihe

I have a three-level multi-nested form in Rails. The setup is like this: Projects have many Milestones, and Milestones have many Notes. The goal is to have everything editable within the page with JavaScript, where we can add multiple new Milestones to a Project within the page, and add new Notes to new and existing Milestones. Everything works as expected, except that when I add new notes to an existing Milestone (new Milestones work fine when adding notes to them), the new notes won't save unless I edit any of the fields that actually belong to the Milestone to mark the form "dirty"/edited. Is there a way to flag the Milestone so that the new Notes that have been added will save? Edit: sorry, it's hard to paste in all of the code because there's so many parts, but here goes: Models class Project < ActiveRecord::Base has_many :notes, :dependent => :destroy has_many :milestones, :dependent => :destroy accepts_nested_attributes_for :milestones, :allow_destroy => true accepts_nested_attributes_for :notes, :allow_destroy => true, :reject_if => proc { |attributes| attributes['content'].blank? } end class Milestone < ActiveRecord::Base belongs_to :project has_many :notes, :dependent => :destroy accepts_nested_attributes_for :notes, :allow_destroy => true, :allow_destroy => true, :reject_if => proc { |attributes| attributes['content'].blank? } end class Note < ActiveRecord::Base belongs_to :milestone belongs_to :project scope :newest, lambda { |*args| order('created_at DESC').limit(*args.first || 3) } end I'm using an jQuery-based, unobtrusive version of Ryan Bates' combo helper/JS code to get this done. Application Helper def add_fields_for_association(f, association, partial) new_object = f.object.class.reflect_on_association(association).klass.new fields = f.fields_for(association, new_object, :child_index => "new_#{association}") do |builder| render(partial, :f => builder) end end I render the form for the association in a hidden div, and then use the following JavaScript to find it and add it as needed. JavaScript function addFields(link, association, content, func) { var newID = new Date().getTime(); var regexp = new RegExp("new_" + association, "g"); var form = content.replace(regexp, newID); var link = $(link).parent().next().before(form).prev(); if (func) { func.call(); } return link; } I'm guessing the only other relevant piece of code that I can think of would be the create method in the NotesController: def create respond_with(@note = @owner.notes.create(params[:note])) do |format| format.js { render :json => @owner.notes.newest(3).all.to_json } format.html { redirect_to((@milestone ? [@project, @milestone, @note] : [@project, @note]), :notice => 'Note was successfully created.') } end end The @owner ivar is created in the following before filter: def load_milestone @milestone = @project.milestones.find(params[:milestone_id]) if params[:milestone_id] end def determine_owner @owner = load_milestone @owner ||= @project end Thing is, all this seems to work fine, except when I'm adding new notes to existing milestones. The milestone has to be "touched" in order for new notes to save, or else Rails won't pay attention.

Hi There, I am trying to submit some data to a PHP script, however the PHP scripts expects the data to arrive in a specific format, like this example which is a dump of the post, Array ( [save] => Add to shortlist [cv_file] => Array ( [849709537] => Y [849709616] => Y [849709633] => Y ) ) The process is currently that a user selects the product they want using checkboxes and then clicks a submit button which fires the PHP scripts, The HTML looks like this, div class="row"> <ul> <li class="drag_check ui-draggable"> <input type="checkbox" id="inp_cv_849709537" name="cv_file[849709537]" class="cv_choice" value="Y"> </li> <li class="id"><a href="/search/cv/849709537">849709537</a></li> <div class="disp"> <li class="location">Huddersfield</li> <li class="status"> Not currently working </li> <li class="education">other</li> <li class="role"> Temporary </li> <li class="salary">£100,000 or more</li> <div class="s"> </div> </div> </ul> <dl> <dt>Current Role</dt> <dd>Developer </dd> <dt>Sectors</dt><dt> </dt><dd> Energy & Utilities, Healthcare, Hospitality & Travel, Installation & Maintenance, Installation & Maintenance </dd> <dt>About Me</dt><dt> </dt><dd></dd> </dl> <div class="s"></div> </div> I am needing to use AJAX instead now, but I need to send the data to PHP in the format it expects here is what I have so far, $('#addshortlist').click(function() { var datastring = ui.draggable.children().attr('name')+"="+ui.draggable.children().val()+"&save=Add to shortlist"; alert(datastring); $.ajax({ type: 'POST', url: '/search', data:ui.draggable.children().attr('name')+"="+ui.draggable.children().val()+"&save=Add to shortlist", success:function(){ alert("Success"+datastring); }, error:function() { alert("Fail"+datastring); } }); return false; }); I would really appreciate any help

boost::serialization of mutual pointers

- by KneLL

First, please take a look at these code: class Key; class Door; class Key { public: int id; Door *pDoor; Key() : id(0), pDoor(NULL) {} private: friend class boost::serialization::access; template <typename A> void serialize(A &ar, const unsigned int ver) { ar & BOOST_SERIALIZATION_NVP(id) & BOOST_SERIALIZATION_NVP(pDoor); } }; class Door { public: int id; Key *pKey; Door() : id(0), pKey(NULL) {} private: friend class boost::serialization::access; template <typename A> void serialize(A &ar, const unsigned int ver) { ar & BOOST_SERIALIZATION_NVP(id) & BOOST_SERIALIZATION_NVP(pKey); } }; BOOST_CLASS_TRACKING(Key, track_selectively); BOOST_CLASS_TRACKING(Door, track_selectively); int main() { Key k1, k_in; Door d1, d_in; k1.id = 1; d1.id = 2; k1.pDoor = &d1; d1.pKey = &k1; // Save data { wofstream f1("test.xml"); boost::archive::xml_woarchive ar1(f1); // !!!!! (1) const Key *pK = &k1; const Door *pD = &d1; ar1 << BOOST_SERIALIZATION_NVP(pK) << BOOST_SERIALIZATION_NVP(pD); } // Load data { wifstream i1("test.xml"); boost::archive::xml_wiarchive ar1(i1); // !!!!! (2) A *pK = &k_in; B *pD = &d_in; // (2.1) //ar1 >> BOOST_SERIALIZATION_NVP(k_in) >> BOOST_SERIALIZATION_NVP(d_in); // (2.2) ar1 >> BOOST_SERIALIZATION_NVP(pK) >> BOOST_SERIALIZATION_NVP(pD); } } The first (1) is a simple question - is it possible to pass objects to archive without pointers? If simply pass objects 'as is' that boost throws exception about duplicated pointers. But I'm confused of creating pointers to save objects. The second (2) is a real trouble. If comment out string after (2.1) then boost will corectly load a first Key object (and init internal Door pointer pDoor), but will not init a second Door (d_in) object. After this I have an inited *k_in* object with valid pointer to Door and empty *d_in* object. If use string (2.2) then boost will create two Key and Door objects somewhere in memory and save addresses in pointers. But I want to have two objects *k_in* and *d_in*. So, if I copy a values of memory objects to local variables then I store only addresses, for example, I can write code after (2.2): d_in.id = pD->id; d_in.pKey = pD->pKey; But in this case I store only a pointer and memory object remains in memory and I cannot delete it, because *d_in.pKey* will be unvalid. And I cannot perform a deep copy with operator=(), because if I write code like this: Key &operator==(const Key &k) { if (this != &k) { id = k.id; // call to Door::operator=() that calls *pKey = *d.pKey and so on *pDoor = *k.pDoor; } return *this; } then I will get a something like recursion of operator=()s of Key and Door. How to implement proper serialization of such pointers?

What is the best way to test using grails using IDEA?

- by egervari

I am seriously having a very non-pleasant time testing using Grails. I will describe my experience, and I'd like to know if there's a better way. The first problem I have with testing is that Grails doesn't give immediate feedback to the developer when .save() fails inside of an integration test. So let's say you have a domain class with 12 fields, and 1 of them is violating a constraint and you don't know it when you create the instance... it just doesn't save. Naturally, the test code afterward is going to fail. This is most troublesome because the thingy under test is probably fine... and the real risk and pain is the setup code for the test itself. So, I've tried to develop the habit of using .save(failOnError: true) to avoid this problem, but that's not something that can be easily enforced by everyone working on the project... and it's kind of bloaty. It'd be nice to turn this on for code that is running as part of a unit test automatically. Integration Tests run slow. I cannot understand how 1 integration test that saves 1 object takes 15-20 seconds to run. With some careful test planning, I've been able to get 1000 tests talking to an actual database and doing dbunit dumps after every test to happen in about the same time! This is dumb. It is hard to run all the unit tests and not integration tests in IDEA. Integration tests are a massive pain. Idea actually shows a GREEN BAR when integration tests fail. The output given by grails indicates that something failed, but it doesn't say what it was. It says to look in the test reports... which forces the developer to launch up their file system to hunt the stupid html file down. What a pain. Then once you got the html file and click to the failing test, it'll tell you a line number. Since these reports are not in the IDE, you can't just click the stack trace to go to that line of code... you gotta go back and find it yourself. ARGGH!@!@! Maybe people put up with this, but I refuse. Testing should not be this painful. It should be fast and painless, or people won't do it. Please help. What is the solution? Rails instead of Grails? Something else entirely? I love the Grails framework, but they never demo their testing for a reason. They have a snazzy framework, but the testing is painful. After having used Scala for the last 1.5 months, and being totally spoiled by ScalaTest... I can't go back to this.

Monorail - Form submission using GET instead of POST

- by Septih

Hello, I'm writing some additions to a Castle MonoRail based site involving an Add and an Edit form. The add form works fine and uses POST but the edit form uses GET. The only major difference I can see is that the edit method is called with the Id of the object being edited in the query string. When the submit button is pressed on the edit form, the only argument passed is this object Id again. Here is the code for the edit form: <form action="edit.ashx" method="post"> <h3>Coupon Description</h3> <textarea name="comments" width="200">$comments</textarea> <br/><br/> <h3>Coupon Actions</h3> <br/> <div>Give Stories</div> <ul class="checklist" style="overflow:auto;height:144px;width:100%"> #foreach ($story in $stories.Values) <li> <label> #set ($associated = "") #foreach($storyId in $storyIds) #if($story.Id == $storyId) #set($associated = " checked='true'") #end #end <input type="checkbox" name="chk_${story.Id}" id="chk_${story.Id}" value="true" class="checkbox" $associated/> $story.Name </label> </li> #end </ul> <br/><br/> <div>Give Credit Amount</div> <input type="text" name="credit" value="$credit" /> <br/><br/> <h3>Coupon Uses</h3> <input type="checkbox" name="multi" #if($multi) checked="true" #end /> Multi-Use Coupon?<br/><br/> <b>OR</b> <br/> <br/> Number of Uses per Coupon: <input type="text" name="uses" value="$uses" /> <br/> <input type="submit" name="Save" /> </form> The differences between this and the add form is the velocity stuff to do with association and the values of the inputs being from the PropertyBag. The Method dealing with this on the controller starts like this: public void Edit(int id) { Coupon coupon = Coupon.GetRepository(User.Site.Id).FindById(id).Value; if(coupon == null) { RedirectToReferrer(); return; } IFutureQueryOfList<Story> stories = Story.GetRepository(User.Site.Id).OnlyReturnEnabled().FindAll("Name", true); if (Params["Save"] == null) { ... } } It reliably gets called but a breakpoint on the Params["Save"] lets me see that the HttpMethod is "GET" and the only arguments passed (In the Form and the Request) are the object Id and additional HTTP headers. At the end of the day I'm not that familiar with MonoRail and this may be a stupid mistake on my behalf, but I would very much appreciate being made a fool out of if it fixes the problem! :) Thanks

Deleting unreferenced child records with nhibernate

- by Chev

Hi There I am working on a mvc app using nhibernate as the orm (ncommon framework) I have parent/child entities: Product, Vendor & ProductVendors and a one to many relationship between them with Product having a ProductVendors collection Product.ProductVendors. I currently am retrieving a Product object and eager loading the children and sending these down the wire to my asp.net mvc client. A user will then modify the list of Vendors and post the updated Product back. I am using a custom model binder to generate the modified Product entity. I am able to update the Product fine and insert new ProductVendors. My problem is that dereferenced ProductVendors are not cascade deleted when specifying Product.ProductVendors.Clear() and calling _productRepository.Save(product). The problem seems to be with attaching the detached instance. Here are my mapping files: Product <?xml version="1.0" encoding="utf-8" ?> <id name="Id"> <generator class="guid.comb" /> </id> <version name="LastModified" unsaved-value="0" column="LastModified" /> <property name="Name" type="String" length="250" /> ProductVendors <?xml version="1.0" encoding="utf-8" ?> <id name="Id"> <generator class="guid.comb" /> </id> <version name="LastModified" unsaved-value="0" column="LastModified" /> <property name="Price" /> <many-to-one name="Product" class="Product" column="ProductId" lazy="false" not-null="true" /> <many-to-one name="Vendor" class="Vendor" column="VendorId" lazy="false" not-null="true" /> Custom Model Binder: using System; using Test.Web.Mvc; using Test.Domain; namespace Spoked.MVC { public class ProductUpdateModelBinder : DefaultModelBinder { private readonly ProductSystem ProductSystem; public ProductUpdateModelBinder(ProductSystem productSystem) { ProductSystem = productSystem; } protected override void OnModelUpdated(ControllerContext controllerContext, ModelBindingContext bindingContext) { var product = bindingContext.Model as Product; if (product != null) { product.Category = ProductSystem.GetCategory(new Guid(bindingContext.ValueProvider["Category"].AttemptedValue)); product.Brand = ProductSystem.GetBrand(new Guid(bindingContext.ValueProvider["Brand"].AttemptedValue)); product.ProductVendors.Clear(); if (bindingContext.ValueProvider["ProductVendors"] != null) { string[] productVendorIds = bindingContext.ValueProvider["ProductVendors"].AttemptedValue.Split(','); foreach (string id in productVendorIds) { product.AddProductVendor(ProductSystem.GetVendor(new Guid(id)), 90m); } } } } } } Controller: [AcceptVerbs(HttpVerbs.Post)] public ActionResult Update(Product product) { using (var scope = new UnitOfWorkScope()) { //product.ProductVendors.Clear(); _productRepository.Save(product); scope.Commit(); } using (new UnitOfWorkScope()) { IList<Vendor> availableVendors = _productSystem.GetAvailableVendors(product); productDetailEditViewModel = new ProductDetailEditViewModel(product, _categoryRepository.Select(x => x).ToList(), _brandRepository.Select(x => x).ToList(), availableVendors); } return RedirectToAction("Edit", "Products", new {id = product.Id.ToString()}); } The following test does pass though: [Test] [NUnit.Framework.Category("ProductTests")] public void Can_Delete_Product_Vendors_By_Dereferencing() { Product product; using(UnitOfWorkScope scope = new UnitOfWorkScope()) { Console.Out.WriteLine("Selecting..."); product = _productRepository.First(); Console.Out.WriteLine("Adding Product Vendor..."); product.AddProductVendor(_vendorRepository.First(), 0m); scope.Commit(); } Console.Out.WriteLine("About to delete Product Vendors..."); using (UnitOfWorkScope scope = new UnitOfWorkScope()) { Console.Out.WriteLine("Clearing Product Vendor..."); _productRepository.Save(product); // seems to be needed to attach entity to the persistance manager product.ProductVendors.Clear(); scope.Commit(); } } Going nuts here as I almost have a very nice solution between mvc, custom model binders and nhibernate. Just not seeing my deletes cascaded. Any help greatly appreciated. Chev

Using AJAX to display error message Ruby on Rails

- by bgadoci

I have built a blog using Ruby on Rails. New to both. I am implementing AJAX pretty effectively until I get to the error handling portion. I allow for comments on posts and do this by rendering a comment partial and remote form in the /views/posts/show.html.erb page. Upon successful save of a comment the show page is updated using views/comments/create.js.rjs and displays a flash notice. I am simply trying to flash a notice when it doesn't save. Searched around and worked this a bit on my own. Can't get it to fly. Here is my code: /views/posts/show.html.erb <div id="comments"> <%= render :partial => @post.comments %> <div id="notice"><%= flash[:notice] %></div> </div> <% remote_form_for [@post, Comment.new] do |f| %> <p> <%= f.label :body, "New Comment" %><br/> <%= f.text_area (:body, :class => "textarea") %> </p> <p> <%= f.label :name, "Name" %><br/> <%= f.text_field (:name, :class => "textfield") %> </p> <p> <%= f.label :email, "Email" %><br/> <%= f.text_field (:email, :class => "textfield") %> </p> <p><%= f.submit "Add Comment" %></p> <% end %> /views/comments/_comment.html.erb <% div_for comment do %> <div id="comment-wrapper"> <% if admin? %> <div id="comment-destroy"><%=link_to_remote "X", :url => [@post, comment], :method => :delete %></div> <% end %> <%= h(comment.body) %><br/><br/> <div class="small">Posted <%= time_ago_in_words(comment.created_at) %> ago by <%= h(comment.name) %> <% if admin? %> | <%= h(comment.email) %> <% end %></div> </div> <% end %> /views/comments/create.js.rjs page.insert_html :bottom, :comments, :partial => @comment page[@comment].visual_effect :highlight page[:new_comment].reset page.replace_html :notice, flash[:notice] flash.discard CommentsController#create def create @post = Post.find(params[:post_id]) @comment = @post.comments.create!(params[:comment]) respond_to do |format| if @comment.save flash[:notice] = "Thanks for adding this comment" format.html { redirect_to @post } format.js else flash[:notice] = "Make sure you include your name and a valid email address" format.html { redirect_to @post } format.js end end end

How to convert an ORM to its subclass using Hibernate ?

- by Gaaston

Hi everybody, For example, I have two classes : Person and Employee (Employee is a subclass of Person). Person : has a lastname and a firstname. Employee : has also a salary. On the client-side, I have a single HTML form where i can fill the person informations (like lastname and firstname). I also have a "switch" between "Person" and "Employee", and if the switch is on Employee I can fill the salary field. On the server-side, Servlets receive informations from the client and use the Hibernate framework to create/update data to/from the database. The mapping i'm using is a single table for persons and employee, with a discriminator. I don't know how to convert a Person in an Employee. I firstly tried to : load the Person p from the database create an empty Employee e object copy values from p into e set the salary value save e into the database But i couldn't, as I also copy the ID, and so Hibernate told me they where two instanciated ORM with the same id. And I can't cast a Person into an Employee directly, as Person is Employee's superclass. There seems to be a dirty way : delete the person, and create an employee with the same informations, but I don't really like it.. So I'd appreciate any help on that :) Some precisions : The person class : public class Person { protected int id; protected String firstName; protected String lastName; // usual getters and setters } The employee class : public class Employee extends Person { // string for now protected String salary; // usual getters and setters } And in the servlet : // type is the "switch" if(request.getParameter("type").equals("Employee")) { Employee employee = daoPerson.getEmployee(Integer.valueOf(request.getParameter("ID"))); modifyPerson(employee, request); employee.setSalary(request.getParameter("salary")); daoPerson.save(employee ); } else { Person person = daoPerson.getPerson(Integer.valueOf(request.getParameter("ID"))); modifyPerson(employee, request); daoPerson.save(person); } And finally, the loading (in the dao) : public Contact getPerson(int ID){ Session session = HibernateSessionFactory.getSession(); Person p = (Person) session.load(Person.class, new Integer(ID)); return p; } public Contact getEmployee(int ID){ Session session = HibernateSessionFactory.getSession(); Employee = (Employee) session.load(Employee.class, new Integer(ID)); return p; } With this, i'm getting a ClassCastException when trying to load a Person using getEmployee. XML Hibernate mapping : <class name="domain.Person" table="PERSON" discriminator-value="P"> <id name="id" type="int"> <column name="ID" /> <generator class="native" /> </id> <discriminator column="type" type="character"/> <property name="firstName" type="java.lang.String"> <column name="FIRSTNAME" /> </property> <property name="lastName" type="java.lang.String"> <column name="LASTNAME" /> </property> <subclass name="domain.Employee" discriminator-value="E"> <property name="salary" column="SALARY" type="java.lang.String" /> </subclass> </class> Is it clear enough ? :-/

PHP script causes segmentation fault then the browser asks me to download the .php file with nothing in it?

- by John

I've noticed an unusual problem with some of my php programs. Sometimes when visiting a page like profile.edit.php, the browser throws a dialogue box asking to download profile.edit.php page. When I download it, there's nothing in the file. profile.edit.php is supposed to be a web form that edits user information. I've noticed this on some of my other php pages as well. I look in my apache error logs, and I see a segmentation fault message: [Mon Mar 08 15:40:10 2010] [notice] child pid 480 exit signal Segmentation fault (11) And also, the issue may or may not appear depending on which server I deploy my application too. Additonal Details This doesn't happen all the time though. It only happens sometimes. For example, profile.edit.php will load properly. But as soon as I hit the save button (form action="profile.edit.php?save=true"), then the page asks me to download profile.edit.php. Could it be that sometimes my php scripts consume too much resources? Sample code Upon save action, my profile.edit.php includes a data_access_object.php file. I traced the code in data_access_object.php to this line here if($params[$this->primaryKey]) { $q = "UPDATE $this->tableName SET ".implode(', ', $fields)." WHERE ".$this->primaryKey." = ?$this->primaryKey"; $this->bind($this->primaryKey, $params[$this->primaryKey], $this->tblFields[$this->primaryKey]['mysqlitype']); } else { $q = "INSERT $this->tableName SET ".implode(', ', $fields); } // Code executes perfectly up to this point // echo 'print this'; exit; // if i uncomment this line, profile.edit.php will actually show 'print this'. If I leave it commented, the browser will ask me to download profile.edit.php if(!$this->execute($q)){ $this->errorSave = -3; return false;} // When I jumped into the function execute(), every line executed as expected, right up to the return statement. And if it helps, here's the function execute($sql) in data_access_object.php function execute($sql) { // find all list types and explode them // eg. turn ?listId into ?listId0,?listId1,?listId2 $arrListParam = array_bubble_up('arrayName', $this->arrBind); foreach($arrListParam as $listName) if($listName) { $explodeParam = array(); $arrList = $this->arrBind[$listName]['value']; foreach($arrList as $key=>$val) { $newParamName = $listName.$key; $this->bind($newParamName,$val,$this->arrBind[$listName]['type']); $explodeParam[] = '?'.$newParamName; } $sql = str_replace("?$listName", implode(',',$explodeParam), $sql); } // replace all ?varName with ? for syntax compliance $sqlParsed = preg_replace('/\?[\w\d_\.]+/', '?', $sql); $this->stmt->prepare($sqlParsed); // grab all the parameters from the sql to create bind conditions preg_match_all('/\?[\w\d_\.]+/', $sql, $matches); $matches = $matches[0]; // store bind conditions $types = ''; $params = array(); foreach($matches as $paramName) { $types .= $this->arrBind[str_replace('?', '', $paramName)]['type']; $params[] = $this->arrBind[str_replace('?', '', $paramName)]['value']; } $input = array('types'=>$types) + $params; // bind it if(!empty($types)) call_user_func_array(array($this->stmt, 'bind_param'), $input); $stat = $this->stmt->execute(); if($GLOBALS['DEBUG_SQL']) echo '<p style="font-weight:bold;">SQL error after execution:</p> ' . $this->stmt->error.'<p> </p>'; $this->arrBind = array(); return $stat; }

L2S DataContext out of synch: row not found or changed

- by awrigley

The Problem I am getting a number of errors that imply that the DataContext, or rather, the way I am using the DataContext is getting out of synch. The error occurs on db.SubmitChanges() where db is my DataContext instance. The error is: Row not found or changed. The problem only occurs intermitently, for example, adding a row then deleting it. If I stop the dev server and restart, the added row is there and I can delete it no problem. Ie, it seems that the problem is related to the DataContext losing track of the rows that have been added. IMPORTANT: Before anyone votes to close this thread, on the basis of it being a duplicate, I have checked the sql server profiler and there is no "Where 0 = 1" in the SQL. I have also recreated the dbml file, so am satisfied that the database schema is in synch with the schema represented by the dbml file. Ie, no cases of mismatched nullable/not nullable columns, etc. My Diagnosis (for what it is worth): It seems to be a problem related to how I am using the DataContext. I am new to MVC, Repositories and Services patterns, so suspect that I have wired things up wrong. The Setup Simple eLearning app in its early stages. Pupils need to be able to add and delete courses (Courses table) to their UserCourses. To do this, I have a service that gets a specific DataContext instance Dependency Injected into its constructor. Service Class Constructor: public class SqlPupilBlockService : IPupilBlockService { DataContext db; public SqlPupilBlockService(DataContext db) { this.db = db; CoursesRepository = new SqlRepository<Course>(db); UserCoursesRepository = new SqlRepository<UserCourse>(db); } // Etc, etc } The CoursesRepository and UserCoursesRepository are both private properties of the service class that are of Type IRepository (just a simple generic repository interface). Sql Respoitory Code: public class SqlRepository<T> : IRepository<T> where T : class { DataContext db; public SqlRepository(DataContext db) { this.db = db; } #region IRepository<T> Members public IQueryable<T> Query { get { return db.GetTable<T>(); } } public List<T> FetchAll() { return Query.ToList(); } public void Add(T entity) { db.GetTable<T>().InsertOnSubmit(entity); } public void Delete(T entity) { db.GetTable<T>().DeleteOnSubmit(entity); } public void Save() { db.SubmitChanges(); } #endregion } The two methods for adding and deleting UserCourses are: Service Methods for Adding and Deleting UserCourses: public void AddUserCourse(int courseId) { UserCourse uc = new UserCourse(); uc.IdCourse = courseId; uc.IdUser = UserId; uc.DateCreated = DateTime.Now; uc.DateAmended = DateTime.Now; uc.Role = "Pupil"; uc.CourseNotes = string.Empty; uc.ActiveStepIndex = 0; UserCoursesRepository.Add(uc); UserCoursesRepository.Save(); } public void DeleteUserCourse(int courseId) { var uc = (UserCoursesRepository.Query.Where(x => x.IdUser == UserId && x.IdCourse == courseId)).Single(); UserCoursesRepository.Delete(uc); UserCoursesRepository.Save(); } Ajax I am using Ajax via Ajax.BeginForm I don't think that is relevant. ASP.NET MVC 3 I am using mvc3, but don't think that is relevant: the errors are related to model code.

Can't figure out this file behavior in IOS 4.2

- by Don Jones

Odd behavior with file behavior. Here's the thing: I'm using the phone camera to snap a picture, and internally generating a thumbnail. I'm saving those as temp files in the Documents directory. Here's the complete code: - (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info { UIImage *photo = [info objectForKey:@"UIImagePickerControllerOriginalImage"]; photo = [self scaleAndRotateImage:photo]; // save photo NSString *docsDir = [NSHomeDirectory() stringByAppendingPathComponent:@"Documents"]; NSLog(@"Writing to %@",docsDir); // save photo file NSLog(@"Saving photo as %@",[NSString stringWithFormat:@"%@/temp_photo.png",docsDir]); [UIImagePNGRepresentation(photo) writeToFile:[NSString stringWithFormat:@"%@/temp_photo.png",docsDir] atomically:YES]; // make and save thumbnail NSLog(@"Saving thumbnail as %@",[NSString stringWithFormat:@"%@/temp_thumb.png",docsDir]); UIImage *thumb = [self makeThumbnail:photo]; [UIImagePNGRepresentation(thumb) writeToFile:[NSString stringWithFormat:@"%@/temp_thumb.png",docsDir] atomically:YES]; NSFileManager *manager = [NSFileManager defaultManager]; NSError *error; NSArray *files = [manager contentsOfDirectoryAtPath:docsDir error:&error]; NSLog(@"\n\nThere are %d files in the documents directory %@",(files.count),docsDir); for (int i = 0; i < files.count; i++) { NSString *filename = [files objectAtIndex:i]; NSLog(@"Seeing filename %@",filename); } // done //[photo release]; //[thumb release]; [self dismissModalViewControllerAnimated:NO]; [delegate textInputFinished]; } As you can see, I've put quite a bit of logging in here in an attempt to figure out my problem (which is coming up). The log output to this point is: Writing to /var/mobile/Applications/77D792DC-A224-4A47-8A4C-BB7C557626F3/Documents Saving photo as /var/mobile/Applications/77D792DC-A224-4A47-8A4C-BB7C557626F3/Documents/temp_photo.png Saving thumbnail as /var/mobile/Applications/77D792DC-A224-4A47-8A4C-BB7C557626F3/Documents/temp_thumb.png There are 3 files in the documents directory /var/mobile/Applications/77D792DC-A224-4A47-8A4C-BB7C557626F3/Documents Seeing filename temp_photo.png Seeing filename temp_text.txt Seeing filename temp_thumb.png This is absolutely as-expected. I clearly have three files on the device. Here's the very next code that operates - the code that received the textInputFinished message: - (void)textInputFinished { NSFileManager *fileManager = [NSFileManager defaultManager]; NSString *docsDir = [NSHomeDirectory() stringByAppendingPathComponent:@"Documents"]; NSError *error; // get next filename NSString *filename; int i = 0; do { i++; filename = [NSString stringWithFormat:@"%@/reminder_%d",docsDir,i]; NSLog(@"Trying filename %@",filename); } while ([fileManager fileExistsAtPath:[filename stringByAppendingString:@".txt"]]); NSLog(@"New base filename is %@",filename); NSArray *files = [fileManager contentsOfDirectoryAtPath:docsDir error:&error]; NSLog(@"There are %d files in the directory %@",(files.count),docsDir); This is testing to get a new, non-temp, not-in-use filename. It does that - but then it says there aren't any files in the documents folder! Here's the logged output: Trying filename /var/mobile/Applications/77D792DC-A224-4A47-8A4C-BB7C557626F3/Documents/reminder_1 New base filename is /var/mobile/Applications/77D792DC-A224-4A47-8A4C-BB7C557626F3/Documents/reminder_1 There are 0 files in the directory /var/mobile/Applications/77D792DC-A224-4A47-8A4C-BB7C557626F3/Documents What the heck? Where did the three files go?

Turn Photos and Home Videos into Movies with Windows Live Movie Maker

- by DigitalGeekery

Are you looking for an easy way to take your digital photos and videos and turn them into a movie or slideshow? Today we’ll take a detailed look at how to do use Windows Live Movie Maker. Installation Windows Live Movie Maker comes bundled as part of the Windows Live Essentials suite (link below). However, you don’t have to install any of the programs you may not want. Take notice of the You’re almost done screen. Before clicking Continue, be sure to uncheck the boxes to set your search provider and homepage. Adding Pictures and Videos Open Windows Live Movie Maker. You can add videos or photos by simply dragging and dropping them onto the storyboard area. You can also click on the storyboard area or on the Add videos and photos button on the Home tab to browse for videos and photos. Windows Live Movie Maker supports most video, image, and audio file types. Select your files and add click Open to add them to Windows Live Movie Maker. By default WLMM doesn’t allow you to add files from network locations…so check out our article on how to add network support to Windows Live MovieMaker if the files you want to add are on a network drive. Layout All of your added clips will appear in the storyboard area on the right, while the currently selected clip will appear in the preview window on the left. You can adjust the size of the two areas by clicking and dragging the dividing line in the middle. Make the clips on the storyboard bigger or smaller by clicking on the thumbnail size icon. The slider at the lower right adjusts the zoom time scale. Previewing your Movie At any time, you can playback your movie and preview how it will look in the Preview window by clicking the space bar, or by pushing the play button under the preview window. You can also manually move the preview bar slider across the storyboard to view the clips as the video progresses. Adjusting Clips on the Storyboard You can click and drag clips on the storyboard to change the order in which the photos and videos appear. Adding Music Nothing brings a movie to life quite like music. Selecting Add music will add your music to the beginning of the movie. Select Add music at the current point to include it in the movie to the current location of your preview bar slider, then browse for your music clip. WLMM supports many common audio files such as WAV, MP3, M4A, WMA, AIFF, and ASF. The music clip will appear above the video / photos clips on the storyboard. You can change the location of music clips by clicking and dragging them to a different location on the storyboard. Add Titles, Captions, and Credits To add a Title screen to your movie, click the Title button on the Home tab. Type your title directly into the text box on the preview screen. The title will be placed at the location of the preview slider on the storyboard. However, you can change the location by clicking and dragging title to other areas of the storyboard. On the Format tab, there are a handful of text settings. You can change the font, color, size, alignment, and transparency. The Adjust group allows you to change the background color, edit the text, and set the length of time the Title will appear in the movie. The Effects group on the Format tab allows you to select an effect for your title screen. By hovering your cursor over each option, you will get a live preview of how each effect will appear in the preview window. Click to apply any of the effects. For captions, select where you want your caption to appear with the preview slider on the storyboard, then click the captions button on the Home tab. Just like the title, you type your caption directly into the text box on the preview screen, and you can make any adjustments by using the Font and Paragraph, Adjust, and Effects groups above. Credits are done the same as titles and captions, except they are automatically placed at the end of the movie. Transitions Go to the Animation tab on the ribbon to apply transitions. Select a clip from the storyboard and hover over one of the transition to see it in the preview window. Click on the transition to apply it to the clip. You can apply transitions separately to clips or hold down Ctrl button while clicking to select multiple clips to which to apply the same transition. Pan and zoom effects are also located on the Animations tab, but can be applied to photos only. Like transition, you can apply them individually to a clip or hold down Ctrl button while clicking to select multiple clips to which to apply the same pan and zoom effect. Once applied, you can adjust the duration of the transitions and pan and zoom effects. You can also click the dropdown for additional transitions or effects. Visual Effects Similar to Pan and Zoom and Transitions, you can apply a variety of Visual Effects to individual or multiple clips. Editing Video and Music Note: This does not actually edit the original video you imported into your Windows Live Movie Maker project, only how it appears in your WLMM project. There are some very basic editing tools located on the Home tab. The Rotate left and Rotate right button will adjust any clip that may be oriented incorrectly. The Fit to music button will automatically adjust the duration of the photos (if you have any in your project) to fit the length of the music in your movie. Audio mix allows you to change the volume level You can also do some slightly more advanced editing from the Edit tab. Select the video clip on the storyboard and click the Trim tool to edit or remove portions of a video clip. Next, click and drag the sliders in the preview windows to select the are you wish to keep. For example, the area outside the sliders is the area trimmed from the movie. The area inside is the section that is kept in the movie. You can also adjust the Start and End points manually on the ribbon. When you are finished, click Save trim. You can also split your video clips. Move the preview slider to the location in the video clip where you’d like to split it, and select Split. Your video will be split into separate sections. Now you can apply different effects or move them to different locations on the storyboard. Editing Music Clips Select the music clip on the storyboard and then the Options tab on the ribbon. You can adjust the music volume by moving the slider right and left. You can also choose to have your music clip fade in or out at the beginning and end of your movie. From the Fade in and Fade out dropdowns, select None, Slow, Medium, or Fast. To adjust the sound of your audio clips, click on the Edit tab, select the Video volume button, and adjust the slider. Move it all the way to the left to mute any background noise in your video clips. AutoMovie As you have seen, Windows Live Movie Maker allows you to add effects, transitions, titles, and more. If you don’t want to do any of that stuff yourself, AutoMovie will automatically add title, credits, cross fade transitions between items, pan and zoom effects to photos, and fit your project to the music. Just select the AutoMovie button on the Home tab. You can go from zero to movie in literally a couple minutes. Uploading to YouTube You can share your video on YouTube directly from Windows Live Movie Maker. Click on the YouTube icon in the Sharing group on the Home tab. You’ll be prompted for your YouTube username and password. Fill in the details about your movie and click Publish. The movie will be converted to WMV before being uploaded to YouTube. As soon as the YouTube conversion is complete, you’re new movie is live and ready to be viewed. Saving your Movie as a Video File Select the icon at the top left, then select Save movie. As you hover your mouse over each of the options, you will see the output display size, aspect ratio, and estimated file size per minute of video. All of these settings will output your movie as a WMV file. (Unfortunately, the only option is to save a movie as a WMV file.) The only difference is how they are encoded based on preset common settings. The Burn to DVD option also outputs a WMV file, but then opens Windows DVD Maker and walks you through the process of creating and burning a DVD. If you choose the Burn to DVD option, close this window when the WMV file conversion is complete and the Windows DVD Maker will prompt you to begin. When your movie is finished, it’s time to relax and enjoy. Conclusion Windows Live Movie Maker makes it easy for the average person to quickly churn out nice looking movies and slideshows from there own pictures and videos. However, long time users of previous editions (formerly called Windows Movie Maker) will likely be disappointed by some features missing in Windows Live Movie Maker that existed in earlier editions.

Ajax Control Toolkit May 2012 Release

- by Stephen.Walther

I’m happy to announce the May 2012 release of the Ajax Control Toolkit. This newest release of the Ajax Control Toolkit includes a new file upload control which displays file upload progress. We’ve also added several significant enhancements to the existing HtmlEditorExtender control such as support for uploading images and Source View. You can download and start using the newest version of the Ajax Control Toolkit by entering the following command in the Library Package Manager console in Visual Studio: Install-Package AjaxControlToolkit Alternatively, you can download the latest version of the Ajax Control Toolkit from CodePlex: http://AjaxControlToolkit.CodePlex.com The New Ajax File Upload Control The most requested new feature for the Ajax Control Toolkit (according to the CodePlex Issue Tracker) has been support for file upload with progress. We worked hard over the last few months to create an entirely new file upload control which displays upload progress. Here is a sample which illustrates how you can use the new AjaxFileUpload control: <%@ Page Language="C#" AutoEventWireup="true" CodeBehind="01_FileUpload.aspx.cs" Inherits="WebApplication1._01_FileUpload" %> <html> <head runat="server"> <title>Simple File Upload</title> </head> <body> <form id="form1" runat="server"> <div> <ajaxToolkit:ToolkitScriptManager runat="server" /> <ajaxToolkit:AjaxFileUpload id="ajaxUpload1" OnUploadComplete="ajaxUpload1_OnUploadComplete" runat="server" /> </div> </form> </body> </html> The page above includes a ToolkitScriptManager control. This control is required to use any of the controls in the Ajax Control Toolkit because this control is responsible for loading all of the scripts required by a control. The page also contains an AjaxFileUpload control. The UploadComplete event is handled in the code-behind for the page: namespace WebApplication1 { public partial class _01_FileUpload : System.Web.UI.Page { protected void ajaxUpload1_OnUploadComplete(object sender, AjaxControlToolkit.AjaxFileUploadEventArgs e) { // Generate file path string filePath = "~/Images/" + e.FileName; // Save upload file to the file system ajaxUpload1.SaveAs(MapPath(filePath)); } } } The UploadComplete handler saves each uploaded file by calling the AjaxFileUpload control’s SaveAs() method with a full file path. Here’s a video which illustrates the process of uploading a file: Warning: in order to write to the Images folder on a production IIS server, you need Write permissions on the Images folder. You need to provide permissions for the IIS Application Pool account to write to the Images folder. To learn more, see: http://learn.iis.net/page.aspx/624/application-pool-identities/ Showing File Upload Progress The new AjaxFileUpload control takes advantage of HTML5 upload progress events (described in the XMLHttpRequest Level 2 standard). This standard is supported by Firefox 8+, Chrome 16+, Safari 5+, and Internet Explorer 10+. In other words, the standard is supported by the most recent versions of all browsers except for Internet Explorer which will support the standard with the release of Internet Explorer 10. The AjaxFileUpload control works with all browsers, even browsers which do not support the new XMLHttpRequest Level 2 standard. If you use the AjaxFileUpload control with a downlevel browser – such as Internet Explorer 9 — then you get a simple throbber image during a file upload instead of a progress indicator. Here’s how you specify a throbber image when declaring the AjaxFileUpload control: <%@ Page Language="C#" AutoEventWireup="true" CodeBehind="02_FileUpload.aspx.cs" Inherits="WebApplication1._02_FileUpload" %> <html> <head id="Head1" runat="server"> <title>File Upload with Throbber</title> </head> <body> <form id="form1" runat="server"> <div> <ajaxToolkit:ToolkitScriptManager ID="ToolkitScriptManager1" runat="server" /> <ajaxToolkit:AjaxFileUpload id="ajaxUpload1" OnUploadComplete="ajaxUpload1_OnUploadComplete" ThrobberID="MyThrobber" runat="server" /> <asp:Image id="MyThrobber" ImageUrl="ajax-loader.gif" Style="display:None" runat="server" /> </div> </form> </body> </html> Notice that the page above includes an image with the Id MyThrobber. This image is displayed while files are being uploaded. I use the website http://AjaxLoad.info to generate animated busy wait images. Drag-And-Drop File Upload If you are using an uplevel browser then you can drag-and-drop the files which you want to upload onto the AjaxFileUpload control. The following video illustrates how drag-and-drop works: Remember that drag-and-drop will not work on Internet Explorer 9 or older. Accepting Multiple Files By default, the AjaxFileUpload control enables you to upload multiple files at a time. When you open the file dialog, use the CTRL or SHIFT key to select multiple files. If you want to restrict the number of files that can be uploaded then use the MaximumNumberOfFiles property like this: <ajaxToolkit:AjaxFileUpload id="ajaxUpload1" OnUploadComplete="ajaxUpload1_OnUploadComplete" ThrobberID="throbber" MaximumNumberOfFiles="1" runat="server" /> In the code above, the maximum number of files which can be uploaded is restricted to a single file. Restricting Uploaded File Types You might want to allow only certain types of files to be uploaded. For example, you might want to accept only image uploads. In that case, you can use the AllowedFileTypes property to provide a list of allowed file types like this: <ajaxToolkit:AjaxFileUpload id="ajaxUpload1" OnUploadComplete="ajaxUpload1_OnUploadComplete" ThrobberID="throbber" AllowedFileTypes="jpg,jpeg,gif,png" runat="server" /> The code above prevents any files except jpeg, gif, and png files from being uploaded. Enhancements to the HTMLEditorExtender Over the past months, we spent a considerable amount of time making bug fixes and feature enhancements to the existing HtmlEditorExtender control. I want to focus on two of the most significant enhancements that we made to the control: support for Source View and support for uploading images. Adding Source View Support to the HtmlEditorExtender When you click the Source View tag, the HtmlEditorExtender changes modes and displays the HTML source of the contents contained in the TextBox being extended. You can use Source View to make fine-grain changes to HTML before submitting the HTML to the server. For reasons of backwards compatibility, the Source View tab is disabled by default. To enable Source View, you need to declare your HtmlEditorExtender with the DisplaySourceTab property like this: <%@ Page Language="C#" AutoEventWireup="true" CodeBehind="05_SourceView.aspx.cs" Inherits="WebApplication1._05_SourceView" %> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html> <head id="Head1" runat="server"> <title>HtmlEditorExtender with Source View</title> </head> <body> <form id="form1" runat="server"> <div> <ajaxToolkit:ToolkitScriptManager ID="ToolkitScriptManager1" runat="server" /> <asp:TextBox id="txtComments" TextMode="MultiLine" Columns="60" Rows="10" Runat="server" /> <ajaxToolkit:HtmlEditorExtender id="HEE1" TargetControlID="txtComments" DisplaySourceTab="true" runat="server" /> </div> </form> </body> </html> The page above includes a ToolkitScriptManager, TextBox, and HtmlEditorExtender control. The HtmlEditorExtender extends the TextBox so that it supports rich text editing. Notice that the HtmlEditorExtender includes a DisplaySourceTab property. This property causes a button to appear at the bottom of the HtmlEditorExtender which enables you to switch to Source View: Note: when using the HtmlEditorExtender, we recommend that you set the DOCTYPE for the document. Otherwise, you can encounter weird formatting issues. Accepting Image Uploads We also enhanced the HtmlEditorExtender to support image uploads (another very highly requested feature at CodePlex). The following video illustrates the experience of adding an image to the editor: Once again, for backwards compatibility reasons, support for image uploads is disabled by default. Here’s how you can declare the HtmlEditorExtender so that it supports image uploads: <ajaxToolkit:HtmlEditorExtender id="MyHtmlEditorExtender" TargetControlID="txtComments" OnImageUploadComplete="MyHtmlEditorExtender_ImageUploadComplete" DisplaySourceTab="true" runat="server" > <Toolbar> <ajaxToolkit:Bold /> <ajaxToolkit:Italic /> <ajaxToolkit:Underline /> <ajaxToolkit:InsertImage /> </Toolbar> </ajaxToolkit:HtmlEditorExtender> There are two things that you should notice about the code above. First, notice that an InsertImage toolbar button is added to the HtmlEditorExtender toolbar. This HtmlEditorExtender will render toolbar buttons for bold, italic, underline, and insert image. Second, notice that the HtmlEditorExtender includes an event handler for the ImageUploadComplete event. The code for this event handler is below: using System.Web.UI; using AjaxControlToolkit; namespace WebApplication1 { public partial class _06_ImageUpload : System.Web.UI.Page { protected void MyHtmlEditorExtender_ImageUploadComplete(object sender, AjaxFileUploadEventArgs e) { // Generate file path string filePath = "~/Images/" + e.FileName; // Save uploaded file to the file system var ajaxFileUpload = (AjaxFileUpload)sender; ajaxFileUpload.SaveAs(MapPath(filePath)); // Update client with saved image path e.PostedUrl = Page.ResolveUrl(filePath); } } } Within the ImageUploadComplete event handler, you need to do two things: 1) Save the uploaded image (for example, to the file system, a database, or Azure storage) 2) Provide the URL to the saved image so the image can be displayed within the HtmlEditorExtender In the code above, the uploaded image is saved to the ~/Images folder. The path of the saved image is returned to the client by setting the AjaxFileUploadEventArgs PostedUrl property. Not surprisingly, under the covers, the HtmlEditorExtender uses the AjaxFileUpload. You can get a direct reference to the AjaxFileUpload control used by an HtmlEditorExtender by using the following code: void Page_Load() { var ajaxFileUpload = MyHtmlEditorExtender.AjaxFileUpload; ajaxFileUpload.AllowedFileTypes = "jpg,jpeg"; } The code above illustrates how you can restrict the types of images that can be uploaded to the HtmlEditorExtender. This code prevents anything but jpeg images from being uploaded. Summary This was the most difficult release of the Ajax Control Toolkit to date. We iterated through several designs for the AjaxFileUpload control – with each iteration, the goal was to make the AjaxFileUpload control easier for developers to use. My hope is that we were able to create a control which Web Forms developers will find very intuitive. I want to thank the developers on the Superexpert.com team for their hard work on this release.

Add Free Google Apps to Your Website or Blog

- by Matthew Guay

Would you like to have an email address from your own domain, but prefer Gmail’s interface and integration with Google Docs? Here’s how you can add the free Google Apps Standard to your site and get the best of both worlds. Note: To signup for Google Apps and get it setup on your domain, you will need to be able to add info to your WordPress blog or change Domain settings manually. Getting Started Head to the Google Apps signup page (link below), and click the Get Started button on the right. Note that we are signing up for the free Google Apps which allows a max of 50 users; if you need more than 50 email addresses for your domain, you can choose Premiere Edition instead for $50/year. Select that you are the Administrator of the domain, and enter the domain or subdomain you want to use with Google Apps. Here we’re adding Google Apps to the techinch.com site, but we could instead add Apps to mail.techinch.com if needed…click Get Started. Enter your name, phone number, an existing email address, and other Administrator information. The Apps signup page also includes some survey questions about your organization, but you only have to fill in the required fields. On the next page, enter a username and password for the administrator account. Note that the user name will also be the administrative email address as [email protected]. Now you’re ready to authenticate your Google Apps account with your domain. The steps are slightly different depending on whether your site is on WordPress.com or on your own hosting service or server, so we’ll show how to do it both ways. Authenticate and Integrate Google Apps with WordPress.com To add Google Apps to a domain you have linked to your WordPress.com blog, select Change yourdomain.com CNAME record and click Continue. Copy the code under #2, which should be something like googleabcdefg123456. Do not click the button at the bottom; wait until we’ve completed the next step. Now, in a separate browser window or tab, open your WordPress Dashboard. Click the arrow beside Upgrades, and select Domains from the menu. Click the Edit DNS link beside the domain name you’re adding to Google Apps. Scroll down to the Google Apps section, and paste your code from Google Apps into the verification code field. Click Generate DNS records when you’re done. This will add the needed DNS settings to your records in the box above the Google Apps section. Click Save DNS records. Now, go back to the Google Apps signup page, and click I’ve completed the steps above. Authenticate Google Apps on Your Own Server If your website is hosted on your own server or hosting account, you’ll need to take a few more steps to add Google Apps to your domain. You can add a CNAME record to your domain host using the same information that you would use with a WordPress account, or you can upload an HTML file to your site’s main directory. In this test we’re going to upload an HTML file to our site for verification. Copy the code under #1, which should be something like googleabcdefg123456. Do not click the button at the bottom; wait until we’ve completed the next step first. Create a new HTML file and paste the code in it. You can do this easily in Notepad: create a new document, paste the code, and then save as googlehostedservice.html. Make sure to select the type as All Files or otherwise the file will have a .txt extension. Upload this file to your web server via FTP or a web dashboard for your site. Make sure it is in the top level of your site’s directory structure, and try visiting it at yoursite.com/googlehostedservice.html. Now, go back to the Google Apps signup page, and click I’ve completed the steps above. Setup Your Email on Google Apps When this is done, your Google Apps account should be activated and ready to finish setting up. Google Apps will offer to launch a guide to step you through the rest of the process; you can click Launch guide if you want, or click Skip this guide to continue on your own and go directly to the Apps dashboard. If you choose to open the guide, you’ll be able to easily learn the ropes of Google Apps administration. Once you’ve completed the tutorial, you’ll be taken to the Google Apps dashboard. Most of the Google Apps will be available for immediate use, but Email may take a bit more setup. Click Activate email to get your Gmail-powered email running on your domain. Add Google MX Records to Your Server You will need to add Google MX records to your domain registrar in order to have your mail routed to Google. If your domain is hosted on WordPress.com, you’ve already made these changes so simply click I have completed these steps. Otherwise, you’ll need to manually add these records before clicking that button. Adding MX Entries is fairly easy, but the steps may depend on your hosting company or registrar. With some hosts, you may have to contact support to have them add the MX records for you. Our site’s host uses the popular cPanel for website administration, so here’s how we added the MX Entries through cPanel. Add MX Entries through cPanel Login to your site’s cPanel, and click the MX Entry link under Mail. Delete any existing MX Records for your domain or subdomain first to avoid any complications or interactions with Google Apps. If you think you may want to revert to your old email service in the future, save a copy of the records so you can switch back if you need. Now, enter the MX Records that Google listed. Here’s our account after we added all of the entries to our account. Finally, return to your Google Apps Dashboard and click the I have completed these steps button at the bottom of the page. Activating Service You’re now officially finished activating and setting up your Google Apps account. Google will first have to check the MX records for your domain; this only took around an hour in our test, but Google warns it can take up to 48 hours in some cases. You may then see that Google is updating its servers with your account information. Once again, this took much less time than Google’s estimate. When everything’s finished, you can click the link to access the inbox of your new Administrator email account in Google Apps. Welcome to Gmail … at your own domain! All of the Google Apps work just the same in this version as they do in the public @gmail.com version, so you should feel right at home. You can return to the Google Apps dashboard from the Administrative email account by clicking the Manage this domain at the top right. In the Dashboard, you can easily add new users and email accounts, as well as change settings in your Google Apps account and add your site’s branding to your Apps. Your Google Apps will work just like their standard @gmail.com counterparts. Here’s an example of an inbox customized with the techinch logo and a Gmail theme. Links to Remember Here are the common links to your Google Apps online. Substitute your domain or subdomain for yourdomain.com. Dashboard https://www.google.com/a/cpanel/yourdomain.com Email https://mail.google.com/a/yourdomain.com Calendar https://www.google.com/calendar/hosted/yourdomain.com Docs https://docs.google.com/a/yourdomain.com Sites https://sites.google.com/a/yourdomain.com Conclusion Google Apps offers you great webapps and webmail for your domain, and let’s you take advantage of Google’s services while still maintaining the professional look of your own domain. Setting up your account can be slightly complicated, but once it’s finished, it will run seamlessly and you’ll never have to worry about email or collaboration with your team again.

April 2013 Release of the Ajax Control Toolkit

- by Stephen.Walther

I’m excited to announce the April 2013 release of the Ajax Control Toolkit. For this release, we focused on improving two controls: the AjaxFileUpload and the MaskedEdit controls. You can download the latest release from CodePlex at http://AjaxControlToolkit.CodePlex.com or, better yet, you can execute the following NuGet command within Visual Studio 2010/2012: There are three builds of the Ajax Control Toolkit: .NET 3.5, .NET 4.0, and .NET 4.5. A Better AjaxFileUpload Control We completely rewrote the AjaxFileUpload control for this release. We had two primary goals. First, we wanted to support uploading really large files. In particular, we wanted to support uploading multi-gigabyte files such as video files or application files. Second, we wanted to support showing upload progress on as many browsers as possible. The previous version of the AjaxFileUpload could show upload progress when used with Google Chrome or Mozilla Firefox but not when used with Apple Safari or Microsoft Internet Explorer. The new version of the AjaxFileUpload control shows upload progress when used with any browser. Using the AjaxFileUpload Control Let me walk-through using the AjaxFileUpload in the most basic scenario. And then, in following sections, I can explain some of its more advanced features. Here’s how you can declare the AjaxFileUpload control in a page: <ajaxToolkit:ToolkitScriptManager runat="server" /> <ajaxToolkit:AjaxFileUpload ID="AjaxFileUpload1" AllowedFileTypes="mp4" OnUploadComplete="AjaxFileUpload1_UploadComplete" runat="server" /> The exact appearance of the AjaxFileUpload control depends on the features that a browser supports. In the case of Google Chrome, which supports drag-and-drop upload, here’s what the AjaxFileUpload looks like: Notice that the page above includes two Ajax Control Toolkit controls: the AjaxFileUpload and the ToolkitScriptManager control. You always need to include the ToolkitScriptManager with any page which uses Ajax Control Toolkit controls. The AjaxFileUpload control declared in the page above includes an event handler for its UploadComplete event. This event handler is declared in the code-behind page like this: protected void AjaxFileUpload1_UploadComplete(object sender, AjaxControlToolkit.AjaxFileUploadEventArgs e) { // Save uploaded file to App_Data folder AjaxFileUpload1.SaveAs(MapPath("~/App_Data/" + e.FileName)); } This method saves the uploaded file to your website’s App_Data folder. I’m assuming that you have an App_Data folder in your project – if you don’t have one then you need to create one or you will get an error. There is one more thing that you must do in order to get the AjaxFileUpload control to work. The AjaxFileUpload control relies on an HTTP Handler named AjaxFileUploadHandler.axd. You need to declare this handler in your application’s root web.config file like this: <configuration> <system.web> <compilation debug="true" targetFramework="4.5" /> <httpRuntime targetFramework="4.5" maxRequestLength="42949672" /> <httpHandlers> <add verb="*" path="AjaxFileUploadHandler.axd" type="AjaxControlToolkit.AjaxFileUploadHandler, AjaxControlToolkit"/> </httpHandlers> </system.web> <system.webServer> <validation validateIntegratedModeConfiguration="false"/> <handlers> <add name="AjaxFileUploadHandler" verb="*" path="AjaxFileUploadHandler.axd" type="AjaxControlToolkit.AjaxFileUploadHandler, AjaxControlToolkit"/> </handlers> <security> <requestFiltering> <requestLimits maxAllowedContentLength="4294967295"/> </requestFiltering> </security> </system.webServer> </configuration> Notice that the web.config file above also contains configuration settings for the maxRequestLength and maxAllowedContentLength. You need to assign large values to these configuration settings — as I did in the web.config file above — in order to accept large file uploads. Supporting Chunked File Uploads Because one of our primary goals with this release was support for large file uploads, we added support for client-side chunking. When you upload a file using a browser which fully supports the HTML5 File API — such as Google Chrome or Mozilla Firefox — then the file is uploaded in multiple chunks. You can see chunking in action by opening F12 Developer Tools in your browser and observing the Network tab: Notice that there is a crazy number of distinct post requests made (about 360 distinct requests for a 1 gigabyte file). Each post request looks like this: http://localhost:24338/AjaxFileUploadHandler.axd?contextKey={DA8BEDC8-B952-4d5d-8CC2-59FE922E2923}&fileId=B7CCE31C-6AB1-BB28-2940-49E0C9B81C64 &fileName=Sita_Sings_the_Blues_480p_2150kbps.mp4&chunked=true&firstChunk=false Each request posts another chunk of the file being uploaded. Notice that the request URL includes a chunked=true parameter which indicates that the browser is breaking the file being uploaded into multiple chunks. Showing Upload Progress on All Browsers The previous version of the AjaxFileUpload control could display upload progress only in the case of browsers which fully support the HTML5 File API. The new version of the AjaxFileUpload control can display upload progress in the case of all browsers. If a browser does not fully support the HTML5 File API then the browser polls the server every few seconds with an Ajax request to determine the percentage of the file that has been uploaded. This technique of displaying progress works with any browser which supports making Ajax requests. There is one catch. Be warned that this new feature only works with the .NET 4.0 and .NET 4.5 versions of the AjaxControlToolkit. To show upload progress, we are taking advantage of the new ASP.NET HttpRequest.GetBufferedInputStream() and HttpRequest.GetBufferlessInputStream() methods which are not supported by .NET 3.5. For example, here is what the Network tab looks like when you use the AjaxFileUpload with Microsoft Internet Explorer: Here’s what the requests in the Network tab look like: GET /WebForm1.aspx?contextKey={DA8BEDC8-B952-4d5d-8CC2-59FE922E2923}&poll=1&guid=9206FF94-76F9-B197-D1BC-EA9AD282806B HTTP/1.1 Notice that each request includes a poll=1 parameter. This parameter indicates that this is a polling request to get the size of the file buffered on the server. Here’s what the response body of a request looks like when about 20% of a file has been uploaded: Buffering to a Temporary File When you upload a file using the AjaxFileUpload control, the file upload is buffered to a temporary file located at Path.GetTempPath(). When you call the SaveAs() method, as we did in the sample page above, the temporary file is copied to a new file and then the temporary file is deleted. If you don’t call the SaveAs() method, then you must ensure that the temporary file gets deleted yourself. For example, if you want to save the file to a database then you will never call the SaveAs() method and you are responsible for deleting the file. The easiest way to delete the temporary file is to call the AjaxFileUploadEventArgs.DeleteTemporaryData() method in the UploadComplete handler: protected void AjaxFileUpload1_UploadComplete(object sender, AjaxControlToolkit.AjaxFileUploadEventArgs e) { // Save uploaded file to a database table e.DeleteTemporaryData(); } You also can call the static AjaxFileUpload.CleanAllTemporaryData() method to delete all temporary data and not only the temporary data related to the current file upload. For example, you might want to call this method on application start to ensure that all temporary data is removed whenever your application restarts. A Better MaskedEdit Extender This release of the Ajax Control Toolkit contains bug fixes for the top-voted issues related to the MaskedEdit control. We closed over 25 MaskedEdit issues. Here is a complete list of the issues addressed with this release: · 17302 MaskedEditExtender MaskType=Date, Mask=99/99/99 Undefined JS Error · 11758 MaskedEdit causes error in JScript when working with 2-digits year · 18810 Maskededitextender/validator Date validation issue · 23236 MaskEditValidator does not work with date input using format dd/mm/yyyy · 23042 Webkit based browsers (Safari, Chrome) and MaskedEditExtender · 26685 MaskedEditExtender@(ClearMaskOnLostFocus=false) adds a zero character when you each focused to target textbox · 16109 MaskedEditExtender: Negative amount, followed by decimal, sets value to positive · 11522 MaskEditExtender of AjaxtoolKit-1.0.10618.0 does not work properly for Hungarian Culture · 25988 MaskedEditExtender – CultureName (HU-hu) > DateSeparator · 23221 MaskedEditExtender date separator problem · 15233 Day and month swap in Dynamic user control · 15492 MaskedEditExtender with ClearMaskOnLostFocus and with MaskedEditValidator with ClientValidationFunction · 9389 MaskedEditValidator – when on no entry · 11392 MaskedEdit Number format messed up · 11819 MaskedEditExtender erases all values beyond first comma separtor · 13423 MaskedEdit(Extender/Validator) combo problem · 16111 MaskedEditValidator cannot validate date with DayMonthYear in UserDateFormat of MaskedEditExtender · 10901 MaskedEdit: The months and date fields swap values when you hit submit if UserDateFormat is set. · 15190 MaskedEditValidator can’t make use of MaskedEditExtender’s UserDateFormat property · 13898 MaskedEdit Extender with custom date type mask gives javascript error · 14692 MaskedEdit error in “yy/MM/dd” format. · 16186 MaskedEditExtender does not handle century properly in a date mask · 26456 MaskedEditBehavior. ConvFmtTime : function(input,loadFirst) fails if this._CultureAMPMPlaceholder == “” · 21474 Error on MaskedEditExtender working with number format · 23023 MaskedEditExtender’s ClearMaskOnLostFocus property causes problems for MaskedEditValidator when set to false · 13656 MaskedEditValidator Min/Max Date value issue Conclusion This latest release of the Ajax Control Toolkit required many hours of work by a team of talented developers. I want to thank the members of the Superexpert team for the long hours which they put into this release.

"Translator by Moth"

- by Daniel Moth

This article serves as the manual for the free Windows Phone 7 app called "Translator by Moth". The app is available from the following link (browse the link on your Window Phone 7 phone, or from your PC with zune software installed): http://social.zune.net/redirect?type=phoneApp&id=bcd09f8e-8211-e011-9264-00237de2db9e Startup At startup the app makes a connection to the bing Microsoft Translator service to retrieve the available languages, and also which languages offer playback support (two network calls total). It populates with the results the two list pickers ("from" and "to") on the "current" page. If for whatever reason the network call fails, you are informed via a message box, and the app keeps trying to make a connection every few seconds. When it eventually succeeds, the language pickers on the "current" page get updated. Until it succeeds, the language pickers remain blank and hence no new translations are possible. As you can guess, if the Microsoft Translation service add more languages for textual translation (or enables more for playback) the app will automatically pick those up. "current" page The "current" page is the main page of the app with language pickers, translation boxes and the application bar. Language list pickers The "current" page allows you to pick the "from" and "to" languages, which are populated at start time. Until these language get populated with the results of the network calls, they remain empty and disabled. When enabled, tapping on either of them brings up on a full screen popup the list of languages to pick from, formatted as English Name followed by Native Name (when the latter is known). The "to" list, in addition to the language names, indicates which languages have playback support via a * in front of the language name. When making a selection for the "to" language, and if there is text entered for translation, a translation is performed (so there is no need to tap on the "translate" application bar button). Note that both language choices are remembered between different launches of the application. text for translation The textbox where you enter the translation is always enabled. When there is nothing entered in it, it displays (centered and in italics) text prompting you to enter some text for translation. When you tap on it, the prompt text disappears and it becomes truly empty, waiting for input via the keyboard that automatically pops up. The text you type is left aligned and not in italic font. The keyboard shows suggestions of text as you type. The keyboard can be dismissed either by tapping somewhere else on the screen, or via tapping on the Windows Phone hardware "back" button, or via taping on the "enter" key. In the latter case (tapping on the "enter" key), if there was text entered and if the "from" language is not blank, a translation is performed (so there is no need to tap on the "translate" application bar button). The last text entered is remembered between application launches. translated text The translated text appears below the "to" language (left aligned in normal font). Until a translation is performed, there is a message in that space informing you of what to expect (translation appearing there). When the "current" page is cleared via the "clear" application bar button, the translated text reverts back to the message. Note a subtle point: when a translation has been performed and subsequently you change the "from" language or the text for translation, the translated text remains in place but is now in italic font (attempting to indicate that it may be out of date). In any case, this text is not remembered between application launches. application bar buttons and menus There are 4 application bar buttons and 4 application bar menus. "translate" button takes the text for translation and translates it to the translated text, via a single network call to the bing Microsoft Translator service. If the network call fails, the user is informed via a message box. The button is disabled when there is no "from" language available or when there is not text for translation entered. "play" button takes the translated text and plays it out loud in a native speaker's voice (of the "to" language), via a single network call to the bing Microsoft Translator service. If the network call fails, the user is informed via a message box. The button is disabled when there is no "to" language available or when there is no translated text available. "clear" button clears any user text entered in the text for translation box and any translation present in the translated text box. If both of those are already empty, the button is disabled. It also stops any playback if there is one in flight. "save" button saves the entire translation ("from" language, "to" language, text for translation, and translated text) to the bottom of the "saved" page (described later), and simultaneously switches to the "saved" page. The button is disabled if there is no translation or the translation is not up to date (i.e. one of the elements have been changed). "swap to and from languages" menu swaps around the "from" and "to" languages. It also takes the translated text and inserts it in the text for translation area. The translated text area becomes blank. The menu is disabled when there is no "from" and "to" language info. "send translation via sms" menu takes the translated text and creates an SMS message containing it. The menu is disabled when there is no translation present. "send translation via email" menu takes the translated text and creates an email message containing it (after you choose which email account you want to use). The menu is disabled when there is no translation present. "about" menu shows the "about" page described later. "saved" page The "saved" page is initially empty. You can add translations to it by translating text on the "current" page and then tapping the application bar "save" button. Once a translation appears in the list, you can read it all offline (both the "from" and "to" text). Thus, you can create your own phrasebook list, which is remembered between application launches (it is stored on your device). To listen to the translation, simply tap on it – this is only available for languages that support playback, as indicated by the * in front of them. The sound is retrieved via a single network call to the bing Microsoft Translator service (if it fails an appropriate message is displayed in a message box). Tap and hold on a saved translation to bring up a context menu with 4 items: "move to top" menu moves the selected item to the top of the saved list (and scrolls there so it is still in view) "copy to current" menu takes the "from" and "to" information (language and text), and populates the "current" page with it (switching at the same time to the current page). This allows you to make tweaks to the translation (text or languages) and potentially save it back as a new item. Note that the action makes a copy of the translation, so you are not actually editing the existing saved translation (which remains intact). "delete" menu deletes the selected translation. "delete all" menu deletes all saved translations from the "saved" page – there is no way to get that info back other than re-entering it, so be cautious. Note: Once playback of a translation has been retrieved via a network call, Windows Phone 7 caches the results. What this means is that as long as you play a saved translation once, it is likely that it will be available to you for some time, even when there is no network connection. "about" page The "about" page provides some textual information (that you can view in the screenshot) including a link to the creator's blog (that you can follow on your Windows Phone 7 device). Use that link to discover the email for any feedback. Other UI design info As you can see in the screenshots above, "Translator by Moth" has been designed from scratch for Windows Phone 7, using the nice pivot control and application bar. It also supports both portrait and landscape orientations, and looks equally good in both the light and the dark theme. Other than the default black and white colors, it uses the user's chosen accent color (which is blue in the screenshot examples above). Feedback and support Please report (via the email on the blog) any bugs you encounter or opportunities for performance improvements and they will be fixed in the next update. Suggestions for new features will be considered, but given that the app is FREE, no promises are made. If you like the app, don't forget to rate "Translator by Moth" on the marketplace. Comments about this post welcome at the original blog.
