• Entity Framework SaveChanges error details

  - by Marek Karbarz

  When saving changes with SaveChanges on a data context is there a way to determine which Entity causes an error? For example, sometimes I'll forget to assign a date to a non-nullable date field and get "Invalid Date Range" error, but I get no information about which entity or which field it's caused by (I can usually track it down by painstakingly going through all my objects, but it's very time consuming). Stack trace is pretty useless as it only shows me an error at the SaveChanges call without any additional information as to where exactly it happened. Note that I'm not looking to solve any particular problem I have now, I would just like to know in general if there's a way to tell which entity/field is causing a problem. Quick sample of a stack trace as an example - in this case an error happened because CreatedOn date was not set on IAComment entity, however it's impossible to tell from this error/stack trace [SqlTypeException: SqlDateTime overflow.

• Mercurial to Mercurial to Subversion Workflow Problem

  - by Dalroth

  We're migrating from Subversion to Mercurial. To facilitate the migration, we're creating an intermediate Mercurial repository that is a clone of our Subversion repository. All developers will be begin switching over to the Mercurial repository, and we'll periodically push changes from the intermediate Mercurial repository to the existing Subversion repository. After a period of time, we'll simply obsolete the Subversion repository and the intermediate Mercurial repository will become the new system of record. Dev 1 Local --+--> Mercurial --+--> Subversion Dev 2 Local --+ + Dev 3 Local --+ + Dev 4 -------------------------+ I've been testing this out, but I keep running into a problem when I push changes from my local repository, to the intermediate Mercurial repository, and then up into our Subversion repository. On my local machine, I have a changeset that is committed and ready to be pushed to our intermediate Mercurial repository. Here you can see it is revision #2263 with hash 625... I push only this changeset to the remote repository. So far, everything looks good. The changeset has been pushed. hg update 1 files updated, 0 files merged, 0 files removed, 0 files unresolved I now switch over to the remote repository, and update the working directory. hg push pushing to svn://... searching for changes [r3834] bmurphy: database namespace pulled 1 revisions saving bundle to /srv/hg/repository/.hg/strip-backup/62539f8df3b2-temp adding branch adding changesets adding manifests adding file changes added 1 changesets with 1 changes to 1 files rebase completed Next, I push the change up to Subversion, works great. At this point, the change is in the Subversion repository and I return attention back to my local client. I pull changes to my local machine. Huh? I've now got two changesets. My original changeset appears as a local branch now. The other changeset has a new revision number 2264, and a new hash 10c1... Anyway, I update my local repo to the new revision. I'm now switched over. So, I finally click the "determine and mark outgoing changesets" and as you can see Mercurial still wants to push out my previous changesets even though they've already been pushed. Clearly, I'm doing something wrong. I also can't merge the two revisions. If I merge the two revisions on my local machine, I end up with a "merge" commit. When I push that merge commit out to the intermediate Mercurial repository, I can no longer push changes out to our Subversion repository. I end up with the following problem: hg update 0 files updated, 0 files merged, 0 files removed, 0 files unresolved hg push pushing to svn://... searching for changes abort: Sorry, can't find svn parent of a merge revision. and I have to rollback the merge to get back to a working state. What am I missing?

• Integrating POP3 client functionality into a C# application?

  - by flesh

  I have a web application that requires a server based component to periodically access POP3 email boxes and retrieve emails. The service then needs to process the emails which will involve: Validating the email against some business rules (does it contain a valid reference in the subject line, which user sent the mail, etc.) Analysing and saving any attachments to disk Take the email body and attachment details and create a new item in the database Or update an existing item where the reference matches the incoming email subject line What is the best way to approach this? I really don't want to have to write a POP3 client from scratch, but I need to be able to customize the processing of emails. Ideally I would be able to plug in some component that does the access and retrieval for me, returning arrays of attachments, body text, subject line, etc. ready for my processing... [ UPDATE: Reviews ] OK, so I have spent a fair amount of time looking into (mainly free) .NET POP3 libraries so I thought I'd provide a short review of some of those mentioned below and a few others: Pop3.net - free - works OK, very basic in terms of functionality provided. This is pretty much just the POP3 commands and some base64 encoding, but it's very straight forward - probably a good introduction Pop3 Wizard - commercial / some open source code - couldn't get this to build, missing DLLs, I wouldn't bother with this C#Mail - free - works well, comes with Mime parser and SMTP client, however the comments are in Japanese (not a big deal) and it didn't work with SSL 'out of the box' - I had to change the SslStream constructor after which it worked no problem OpenPOP - free - hasn't been updated for about 5 years so it's current state is .NET 1.0, doesn't support SSL but that was no problem to resolve - I just replaced the existing stream with an SslStream and it worked. Comes with Mime parser. Of the free libraries, I'd go for C#Mail or OpenPOP. I looked at a few commercial libraries: Chillkat, Rebex, RemObjects, JMail.net. Based on features, price and impression of the company I would probably go for Rebex and may in the future if my requirements change or I run into production issues with either of C#Mail or OpenPOP. In case anyone's needs it, this is the replacement SslStream constructor that I used to enable SSL with C#Mail and OpenPOP: SslStream stream = new SslStream(clientSocket.GetStream(), false, delegate(object sender, X509Certificate cert, X509Chain chain, SslPolicyErrors errors) { return true; });

• Return Json causes save file dialog in asp.net mvc

  - by Eran

  Hi, I'm integrating jquery fullcalendar into my application. Here is the code i'm using: in index.aspx: <script type="text/javascript"> $(document).ready(function() { $('#calendar').fullCalendar({ events: "/Scheduler/CalendarData" }); }); </script> <div id="calendar"> </div> Here is the code for Scheduler/CalendarData: public ActionResult CalendarData() { IList<CalendarDTO> tasksList = new List<CalendarDTO>(); tasksList.Add(new CalendarDTO { id = 1, title = "Google search", start = ToUnixTimespan(DateTime.Now), end = ToUnixTimespan(DateTime.Now.AddHours(4)), url = "www.google.com" }); tasksList.Add(new CalendarDTO { id = 1, title = "Bing search", start = ToUnixTimespan(DateTime.Now.AddDays(1)), end = ToUnixTimespan(DateTime.Now.AddDays(1).AddHours(4)), url = "www.bing.com" }); return Json(tasksList,JsonRequestBehavior.AllowGet); } private long ToUnixTimespan(DateTime date) { TimeSpan tspan = date.ToUniversalTime().Subtract( new DateTime(1970, 1, 1, 0, 0, 0)); return (long)Math.Truncate(tspan.TotalSeconds); } public ActionResult Index() { return View("Index"); } I also have the following code inside head tag in site.master: <asp:ContentPlaceHolder ID="ContentPlaceHolder1" runat="server" /> <link href="<%= Url.Content("~/Content/jquery-ui-1.7.2.custom.css") %>" rel="stylesheet" type="text/css" /> <link href="~Perspectiva/Content/Site.css" rel="stylesheet" type="text/css" /> <link href="~Perspectiva/Content/fullcalendar.css" rel="stylesheet" type="text/css" /> <script src="~Perspectiva/Scripts/jquery-1.4.2.js" type="text/javascript"></script> <script src="~Perspectiva/Scripts/fullcalendar.js" type="text/javascript"></script> <script src="/Scripts/MicrosoftAjax.debug.js" type="text/javascript"></script> <script src="/Scripts/MicrosoftMvcAjax.debug.js" type="text/javascript"></script> Everything I did was pretty much copied from http://szahariev.blogspot.com/2009/08/jquery-fullcalendar-and-aspnet-mvc.html When navigating to /scheduler/calendardata I get a prompt for saving the json data which contents are exactly what I created in the CalendarData function. What do I need to do in order to render the page correctly? Thanks in advance, Eran

• Lots of questions about file I/O (reading/writing message strings)

  - by Nazgulled

  Hi, For this university project I'm doing (for which I've made a couple of posts in the past), which is some sort of social network, it's required the ability for the users to exchange messages. At first, I designed my data structures to hold ALL messages in a linked list, limiting the message size to 256 chars. However, I think my instructors will prefer if I save the messages on disk and read them only when I need them. Of course, they won't say what they prefer, I need to make a choice and justify the best I can why I went that route. One thing to keep in mind is that I only need to save the latest 20 messages from each user, no more. Right now I have an Hash Table that will act as inbox, this will be inside the user profile. This Hash Table will be indexed by name (the user that sent the message). The value for each element will be a data structure holding an array of size_t with 20 elements (20 messages like I said above). The idea is to keep track of the disk file offsets and bytes written. Then, when I need to read a message, I just need to use fseek() and read the necessary bytes. I think this could work nicely... I could use just one single file to hold all messages from all users in the network. I'm saying one single file because a colleague asked an instructor about saving the messages from each user independently which he replied that it might not be the best approach cause the file system has it's limits. That's why I'm thinking of going the single file route. However, this presents a problem... Since I only need to save the latest 20 messages, I need to discard the older ones when I reach this limit. I have no idea how to do this... All I know is about fread() and fwrite() to read/write bytes from/to files. How can I go to a file offset and say "hey, delete the following X bytes"? Even if I could do that, there's another problem... All offsets below that one will be completely different and I would have to process all users mailboxes to fix the problem. Which would be a pain... So, any suggestions to solve my problems? What do you suggest?

• jQuery unbinding click event when maximum number of children are displayed

  - by RyanP13

  I have a personal details form that alows you to enter a certain number of dependants which is determined by the JSP application. The first dependant is visible and the user has the option to add dependants up to the maximum number. All other dependants are hidden by default and are displayed when a user clicks the 'Add another dependant button'. When the maximum number of dependants has been reached the button is greyed out and a message is generated via jQuery and displayed to tell the user exactly this. The issue i am having is when the maximum number of dependants has been reached the message is displayed but then the user can click the button to add more dependants and the message keeps on generating. I thought unbinding the click event would sort this but it seems to still be able to generate a second message. Here is the function i wrote to generate the message: // Dependant message function function maxDependMsg(msgElement) { // number of children can change per product, needs to be dynamic // count number of dependants in HTML var $dependLength = $("div.dependant").length; // add class maxAdd to grey out Button // create maximum dependants message and display, will not be created if JS turned off $(msgElement) .addClass("maxAdd") .after($('<p>') .addClass("maxMsg") .append("The selected web policy does not offer cover for more than " + $dependLength + " children, please contact our customer advisers if you wish discuss alternative policies available.")); } There is a hyperlink with a click event attached like so: $("a.add").click(function(){ // Show the next hidden table on clicking add child button $(this).closest('form').find('div.dependant:hidden:first').show(); // Get the number of hidden tables var $hiddenChildren = $('div.dependant:hidden').length; if ($hiddenChildren == 0) { // save visible state of system message $.cookies.set('cpqbMaxDependantMsg', 'visible'); // show system message that you can't add anymore dependants than what is on page maxDependMsg("a.add"); $(this).unbind("click"); } // set a cookie for the visible state of all child tables $('div.dependant').each(function(){ var $childCount = $(this).index('div.dependant'); if ($(this).is(':visible')) { $.cookies.set('cpqbTableStatus' + $childCount, 'visible'); } else { $.cookies.set('cpqbTableStatus' + $childCount, 'hidden'); } }); return false; }); All of the cookies code is for state saving when users are going back and forward through the process.

• Using Android SAXParser, one my my XML Elements is mysteriously breaking in half.

  - by Drennen

  And its not '&' Im using the SAXParser object do parse the actual XML. This is normally done by passing a URL to the XMLReader.Parse method. Because my XML is coming from a POST request to a webservice, I am saving that result as a String and then employing StringReader / InputSource to feed this string back to the XMLReader.Parse method. However, something strange is happening at the 2001st character of the XMLstring. The 'characters' method of the document handler is being called TWICE in between the startElement and endElement methods, effectively breaking my string (in this case a project title) into two pieces. Because I am instantiating objects in my characters method, I am getting two objects instead of one. This line, about 2000 chars into the string fires 'characters' two times, breaking between "Lower" and "Level" <title>SUMC-BOOKSTORE, LOWER LEVEL RENOVATIONS</title> When I bypass the StringReader / InputSource workaround and feed a flat XML file to XMLReader.Parse, it works absolutely fine. Something about StringReader and or InputSource is somehow screwing this up. Here is my method that takes and XML string and parses is through the SAXParser. public void parseXML(String XMLstring) { try { SAXParserFactory spf = SAXParserFactory.newInstance(); SAXParser sp = spf.newSAXParser(); XMLReader xr = sp.getXMLReader(); xr.setContentHandler(this); // Something is happening in the StringReader or InputSource // That cuts the XML element in half at the 2001 character mark. StringReader sr = new StringReader(XMLstring); InputSource is = new InputSource(sr); xr.parse(is); } catch (IOException e) { Log.e("CMS1", e.toString()); } catch (SAXException e) { Log.e("CMS2", e.toString()); } catch (ParserConfigurationException e) { Log.e("CMS3", e.toString()); } } I would greatly appreciate any ideas on how to not have 'characters' firing off twice when I get to this point in the XML String. Or, show me how to use a POST request and still pass off the URL to the Parse function. THANK YOU.

• c# Properties.Settings.Default Doesn't work as expected

  - by Jack

  I've been working on a program to automate my backup checks with LogMeIn backup (a windows forms based program). I now need a way to store user settings, to save information easily. I've never worked with the Application/User settings that is somewhat "built-in" - and decided to try it, but ran into problems. I added four settings for now: IncludeCriteria (Specialized.StringCollection) ExcludeCriteria (Specialized.StringCollection) ReportPath (string) ReportType (int) But the behavior doesn't act as expected (go figure). After saving some values in my program, I go back into edit/view my settings values using the VS 2008 settings editor. None of my values are stored. While I think this may be because those values are just default values, wouldn't that be where they can be stored/read/changed? Here is my load form code (still very unrefined): private void setupForm() { txtPath.Text = BackupReport.Properties.Settings.Default.ReportPath == null ? "" : BackupReport.Properties.Settings.Default.ReportPath; if (BackupReport.Properties.Settings.Default.ReportType == 0) { radioHTML.Checked = true; } else radioExcel.Checked = true; if (BackupReport.Properties.Settings.Default.IncludeCriteria.Count > 0) { listIncludeCriteria.DataSource = Properties.Settings.Default.IncludeCriteria; //foreach (string s in Properties.Settings.Default.IncludeCriteria) // listIncludeCriteria.Items.Add(s); } if (BackupReport.Properties.Settings.Default.ExcludeCriteria.Count > 0) { listExcludeCriteria.DataSource = BackupReport.Properties.Settings.Default.ExcludeCriteria; //foreach (string s in Properties.Settings.Default.ExcludeCriteria) // listExcludeCriteria.Items.Add(s); } } listIncludeCriteria is just a listbox. When the user saves I call this method: private void saveSettings() { //var settings = BackupReport.Properties.Settings; if (txtPath.Text != "") { BackupReport.Properties.Settings.Default.ReportPath = txtPath.Text; } if (listIncludeCriteria.Items.Count > 0) { //BackupReport.Properties.Settings.Default.IncludeCriteria = (StringCollection)listIncludeCriteria.Items.AsQueryable(); foreach (var i in listIncludeCriteria.Items) { if (!isIncludeDuplicate(i.ToString())) BackupReport.Properties.Settings.Default.IncludeCriteria.Add(i.ToString()); } } if (listExcludeCriteria.Items.Count > 0) { //BackupReport.Properties.Settings.Default.ExcludeCriteria = (StringCollection)listExcludeCriteria.Items.AsQueryable(); foreach (var i in listExcludeCriteria.Items) { if (!isExcludeDuplicate(i.ToString())) Properties.Settings.Default.ExcludeCriteria.Add(i.ToString()); } } if (radioExcel.Checked == true) BackupReport.Properties.Settings.Default.ReportType = 1; else BackupReport.Properties.Settings.Default.ReportType = 0; BackupReport.Properties.Settings.Default.Save(); //Properties.Settings.Default.Save(); this.DialogResult = DialogResult.OK; this.Close(); } The wierd thing is when the form loads, the path I put in the first time seems to come up (ReportPath) - even the listBoxes are populated with a bunch of crap I put in - yet I cant find these values anywhere. Any help would be appreciated! Josh

• Jruby Gems-in-a-jar issue

  - by antonio

  Hi all, I am trying to write some code in ruby (using jruby) to be compiled to java bytecode with jrubyc and deployed to a remote machine where it will be run on the JVM (no ruby available there). Everything works fine as long as I am happy to stick with the standard jruby library. As explained on the jruby website, I simply copy the jruby-complete.jar library to the remote machine and include it in the classpath at runtime. I fire my compiled script and it works: cool! The problems start when I need some other libraries (typically rubygems) to run my script. I am aware of cool stuff like rawr, -which I successfully tested- to put together all you need in a single package. However that is not the solution I am looking for: I will have many small scripts to run independently and I don't want each of them to grow to at least 10 MB just because I insanely include the jruby-complete.jar in each of them. What I would like is to compile a .jar for each of the libraries that I will need to use, put all of them in a common folder on the remote machine and include them at runtime in the classpath when I run my compiled jruby scripts on the JVM. This said, I tried to follow the instructions here: http://blog.nicksieger.com/articles/2009/01/10/jruby-1-1-6-gems-in-a-jar I tried exactly the example shown there, with the "chronic" gem. Going step by step: Install the gem locally: java -jar jruby-complete-1.1.6.jar -S gem install -i ./chronic chronic --no-rdoc --no-ri Package it into a jar: jar cf chronic.jar -C chronic . Write a two lines test script, saving it as testt.rb: require 'chronic' Chronic.parse('tomorrow') Compile with: jrubyc testt.rb Run the resulting java class testt.class with the following (having both jruby-complete.jar and chronic.jar in the same folder as the java class): java -cp .:/jruby-complete.jar:./chronic.jar testt I get the following error: Exception in thread "main" file:/Users/ave2/NetBeansProjects/jrubywatir/lib/jruby-complete.jar!/METAINF/jruby.home/lib/ruby/site_ruby/shared/builtin/core_ext/symbol.rb:1:in `const_missing': uninitialized constant Chronic (NameError) from testt.rb:2 ...internal jruby stack elided... from Module.const_missing(testt.rb:2) from (unknown).(unknown)(:1) I really don't understand what I am doing wrong, and I am totally stuck on this. I am a noob in Ruby, much more used to Python: don't miss a chance to convert an infidel! :-) Thanks.

• Rails: radio button selection for nested forms objects

  - by satynos

  I have the following form for photo_album which uses the nested forms feature of the Rails in saving the photos while updating the photo_album. And having trouble with the selection of radio button value. I want only one of the photos be able to select as the album cover, but due to the way rails produces form element ids and names, I am able to select all of the photos as album covers. Is there any workaround? <% form_for @photo_album do |f| %> <%= f.error_messages %> <% @photo_album.photos.each do |photo| %> <% f.fields_for :photos, photo do |photo_fields| %> <p> <%= image_tag url_for_image_column(photo, "data", :thumb) %> </p> <p> <%= photo_fields.label :title %> <%= photo_fields.text_field :title %> </p> <p> <%= photo_fields.label :body %> <%= photo_fields.text_area :body %> </p> <p> <%= photo_fields.radio_button :cover, "1" %> <%= photo_fields.label :cover, 'Album Cover', :class => 'option' %> <%= photo_fields.check_box :_delete %> <%= photo_fields.label :_delete, 'Delete', :class => 'option' %> </p> <% end %> <% end %> <p> <%= f.submit @photo_album.new_record? ? 'Create' : 'Update' %> </p> <% end %> And following is the html produced by rails (which is part of the problem) for radio buttons: <p> <input type="radio" value="1" name="photo_album[photos_attributes][0][cover]" id="photo_album_photos_attributes_0_cover_1"/> <label for="photo_album_photos_attributes_0_cover" class="option">Album Cover</label> <input type="hidden" value="0" name="photo_album[photos_attributes][0][_delete]"/><input type="checkbox" value="1" name="photo_album[photos_attributes][0][_delete]" id="photo_album_photos_attributes_0__delete"/> <label for="photo_album_photos_attributes_0__delete" class="option">Delete</label> </p>

• Streaming Video with Blackberry Simulator

  - by Jenny

  So, I wrote a quick little app for the iphone that takes in an http URL, and plays the .mp4 video located at that URL (it does more than that, of course, but that's the meat of it). Naturally, I wanted to have it on more than just a single mobile platform, so I decided to target Blackberry next. However, I'm running into a lot of problems with the Blackberry Environment. First of all, I learn that I can only download 256k files! I learn how to set that variable in my MDS simulator (and learn that this is NOT a production solution, because any end users will have to have their BES or MDS admin change the setting there). Then, I find a video less than 2 MB I can practice with. Going to the browser prompts me to save the video (rather than it playing in the browser like I expected). After saving the video, it refuses to play, saying it's the wrong format. So. I can't find a reference to IF Blackberry can stream with HTTP (i"ve heard it CAN use RTSP, though, and heard some rumors that it can't use HTTP, which would really suck). I also can't find a reference to what format blackberry uses (although I can find a million programs that will convert one file to the 'blackberry' format). Surely SOMEONE must have tried to stream video with the blackberry before. How did they go about doing so? Is it just a hopeless pipedream? Will I have to go with RTSP? Sorry for the lack of a concrete question...I'm just really lost, and I hate how so many tutorials or forum posts seem to assume I know the capabilities of the Blackberry... Edit: I finally found out that the .3gp (which I'd never heard of ) format is what Blackberry uses. Still have no idea how to stream videos off the web, though. I found a tutorial: http://www.blackberry.com/knowledgecenterpublic/livelink.exe/fetch/2000/348583/800332/1089414/How%5FTo%5F-%5FPlay%5Fvideo%5Fwithin%5Fa%5FBlackBerry%5Fsmartphone%5Fapplication.html?nodeid=1383173&vernum=0 That seemed to be useful, but the code doesn't work if you give it a URL (even though it claims it does).

• How can I close a Window using the OS-X ScriptingBridge framework, from Perl?

  - by Gavin Brock

  Problem... Since MacPerl is no longer supported on 64bit perl, I am trying alternative frameworks to control Terminal.app. I am trying the ScriptingBridge, but have run into a problem passing an enumerated string to the closeSaving method using the PerlObjCBridge. I want to call: typedef enum { TerminalSaveOptionsYes = 'yes ' /* Save the file. */, TerminalSaveOptionsNo = 'no ' /* Do not save the file. */, TerminalSaveOptionsAsk = 'ask ' /* Ask the user whether or not to save the file. */ } TerminalSaveOptions; - (void) closeSaving:(TerminalSaveOptions)saving savingIn:(NSURL *)savingIn; // Close a document. Attempted Solution... I have tried: #!/usr/bin/perl use strict; use warnings; use Foundation; # Load the ScriptingBridge framework NSBundle->bundleWithPath_('/System/Library/Frameworks/ScriptingBridge.framework')->load; @SBApplication::ISA = qw(PerlObjCBridge); # Set up scripting bridge for Terminal.app my $terminal = SBApplication->applicationWithBundleIdentifier_("com.apple.terminal"); # Open a new window, get back the tab my $tab = $terminal->doScript_in_('exec sleep 60', undef); warn "Opened tty: ".$tab->tty->UTF8String; # Yes, it is a tab # Now try to close it # Simple idea eval { $tab->closeSaving_savingIn_('no ', undef) }; warn $@ if $@; # Try passing a string ref my $no = 'no '; eval { $tab->closeSaving_savingIn_(\$no, undef) }; warn $@ if $@; # Ok - get a pointer to the string my $pointer = pack("P4", $no); eval { $tab->closeSaving_savingIn_($pointer, undef) }; warn $@ if $@; eval { $tab->closeSaving_savingIn_(\$pointer, undef) }; warn $@ if $@; # Try a pointer decodes as an int, like PerlObjCBridge uses my $int_pointer = unpack("L!", $pointer); eval { $tab->closeSaving_savingIn_($int_pointer, undef) }; warn $@ if $@; eval { $tab->closeSaving_savingIn_(\$int_pointer, undef) }; warn $@ if $@; # Aaarrgghhhh.... As you can see, all my guesses at how to pass the enumerated string fail. Before you flame me... I know that I could use another language (ruby, python, cocoa) to do this but that would require translating the rest of the code. I might be able to use CamelBones, but I don't want to assume my users have it installed. I could also use the NSAppleScript framework (assuming I went to the trouble of finding the Tab and Window IDs) but it seems odd to have to resort to it for just this one call.

• read user Input of custom dialogs

  - by urobo

  I built a custom dialog starting from an AlertDialog to obtain login information from a user. So the dialog contains two EditText fields, using the layoutinflater service I obtain the layout and I'm saving a reference to the fields. LayoutInflater inflater = (LayoutInflater) Home.this.getSystemService(LAYOUT_INFLATER_SERVICE); layoutLogin = inflater.inflate(R.layout.login,(ViewGroup) findViewById(R.id.rl)); usernameInput =((EditText)findViewById(R.id.getNewUsername)); passwordInput = ((EditText)findViewById(R.id.getNewPassword)); Then I have my overridden onCreateDialog(...) : { AlertDialog d = null; AlertDialog.Builder builder = new AlertDialog.Builder(this); switch(id){ ... case Home.DIALOG_LOGIN: builder.setView(layoutLogin); builder.setMessage("Sign in to your DyCaPo Account").setCancelable(false); d=builder.create(); d.setTitle("Login"); Message msg = new Message(); msg.setTarget(Home.this.handleLogin); Bundle data = new Bundle(); data.putString("username", usernameInput.getText().toString());// <---null pointer Exception data.putString("password", passwordInput.getText().toString()); msg.setData(data); d.setButton(Dialog.BUTTON_NEUTRAL,"Sign in",msg); break; ... return d; } and the handler set in the Message: private Handler handleLogin= new Handler(){ /* (non-Javadoc) * @see android.os.Handler#handleMessage(android.os.Message) */ @Override public void handleMessage(Message msg) { // TODO Auto-generated method stub Log.d("Message Received", msg.getData().getString("username")+ msg.getData().getString("password")); } }; which for now works as a debugging tool. That's all. The Question is: what am I doing wrong? Because when I reach the line highlighted in the code ( the line in which I read the fields in the dialog ) I always get a null pointer exception. Could somebody please tell me the reason why it is so? And give some guidelines to work with dialogs. Thanks in advance!

• Unable to cast lists with Reflection in C#

  - by DrLazer

  I am having a lot of trouble with Reflection in C# at the moment. The app I am writing allows the user to modify the attributes of certain objects using a config file. I want to be able to save the object model (users project) to XML. The function below is called in the middle of a foreach loop, looping through a list of objects that contain all the other objects in the project within them. The idea is, that it works recursively to translate the object model into XML. Dont worry about the call to "Unreal" that just modifes the name of the objects slightly if they contain certain words. private void ReflectToXML(object anObject, XmlElement parentElement) { Type aType = anObject.GetType(); XmlElement anXmlElement = m_xml.CreateElement(Unreal(aType.Name)); parentElement.AppendChild(anXmlElement); PropertyInfo[] pinfos = aType.GetProperties(); //loop through this objects public attributes foreach (PropertyInfo aInfo in pinfos) { //if the attribute is a list Type propertyType = aInfo.PropertyType; if ((propertyType.IsGenericType)&&(propertyType.GetGenericTypeDefinition() == typeof(List<>))) { List<object> listObjects = (aInfo.GetValue(anObject,null) as List<object>); foreach (object aListObject in listObjects) { ReflectToXML(aListObject, anXmlElement); } } //attribute is not a list else anXmlElement.SetAttribute(aInfo.Name, ""); } } If an object attributes are just strings then it should be writing them out as string attributes in the XML. If an objects attributes are lists, then it should recursively call "ReflectToXML" passing itself in as a parameter, thereby creating the nested structure I require that nicely reflect the object model in memory. The problem I have is with the line List<object> listObjects = (aInfo.GetValue(anObject,null) as List<object>); The cast doesn't work and it just returns null. While debugging I changed the line to object temp = aInfo.GetValue(anObject,null); slapped a breakpoint on it to see what "GetValue" was returning. It returns a "Generic list of objects" Surely I should be able to cast that? The annoying thing is that temp becomes a generic list of objects but because i declared temp as a singular object, I can't loop through it because it has no Enumerator. How can I loop through a list of objects when I only have it as a propertyInfo of a class? I know at this point I will only be saving a list of empty strings out anyway, but thats fine. I would be happy to see the structure save out for now. Thanks in advance

• Firefox logs invalid URL?

  - by thanks for help

  I'm writing an extension for firefox. Using dom.location to keep track of visited search results pages, i'm getting this url http://www.google.com/search?hl=en&source=hp&q=hi&aq=f&aqi=&oq=&fp=642c18fb4411ca2e . If you click it, the google search results for "hi" should come up. You'll know that from the title bar - because the rest of the page won't load. This happens with any google search. Oddly enough, if you cut part of it off, so say, http://www.google.com/search?hl=en&source=hp&q=hi - it works! But Googling "hi" myself does give me a longish URL - http://www.google.com/#hl=en&source=hp&q=hi&aq=f&aqi=&oq=&fp=db658cc5049dc510 . I know for a fact that the first time that URL was visited, the page loaded, I did it myself. Can anyone make reason out of this? I just tried my experiment again, this time saving the original URL in the location bar. It turns out, dom.location.href is giving a different value. How is this happening? Original: http://www.google.com/#hl=en&source=hp&q=hi&aq=f&aqi=&oq=&fp=642c18fb4411ca2e dom.location.href http://www.google.com/search?hl=en&source=hp&q=hi&aq=f&aqi=&oq=&fp=642c18fb4411ca2e window.addEventListener("load", function() { myExtension.init(); }, false); var myExtension = { init: function() { var appcontent = document.getElementById("appcontent"); // browser if(appcontent) appcontent.addEventListener("DOMContentLoaded", myExtension.onPageLoad, true); var messagepane = document.getElementById("messagepane"); // mail if(messagepane) messagepane.addEventListener("load", function () { myExtension.onPageLoad(); }, true); }, onPageLoad: function(aEvent) { var doc = aEvent.originalTarget; // doc is document that triggered "onload" event // do something with the loaded page. // doc.location is a Location object (see below for a link). // You can use it to make your code executed on certain pages only. var url = doc.location.href; if (url.match(/(?:p|q)(?:=)([^%]*)/)) {alert("MATCH" + url);resultsPages.push(url);} else {alert(url); } } This snippet comes directly from Mozilla with the matching and alerts my own. I apologize for not posting the code earlier.

• Challenge: Neater way of currying or partially applying C#4's string.Join

  - by Damian Powell

  Background I recently read that .NET 4's System.String class has a new overload of the Join method. This new overload takes a separator, and an IEnumerable<T> which allows arbitrary collections to be joined into a single string without the need to convert to an intermediate string array. Cool! That means I can now do this: var evenNums = Enumerable.Range(1, 100) .Where(i => i%2 == 0); var list = string.Join(",",evenNums); ...instead of this: var evenNums = Enumerable.Range(1, 100) .Where(i => i%2 == 0) .Select(i => i.ToString()) .ToArray(); var list = string.Join(",", evenNums); ...thus saving on a conversion of every item to a string, and then the allocation of an array. The Problem However, being a fan of the functional style of programming in general, and method chaining in C# in particular, I would prefer to be able to write something like this: var list = Enumerable.Range(1, 100) .Where(i => i%2 == 0) .string.Join(","); This is not legal C# though. The closest I've managed to get is this: var list = Enumerable.Range(1, 100) .Where(i => i%2 == 0) .ApplyTo( Functional.Curry<string, IEnumerable<object>, string> (string.Join)(",") ); ...using the following extension methods: public static class Functional { public static TRslt ApplyTo<TArg, TRslt>(this TArg arg, Func<TArg, TRslt> func) { return func(arg); } public static Func<T1, Func<T2, TResult>> Curry<T1, T2, TResult>(this Func<T1, T2, TResult> func) { Func<Func<T1, T2, TResult>, Func<T1, Func<T2, TResult>>> curried = f => x => y => f(x, y); return curried(func); } } This is quite verbose, requires explicit definition of the parameters and return type of the string.Join overload I want to use, and relies upon C#4's variance features because we are defining one of the arguments as IEnumerable rather than IEnumerable. The Challenge Can you find a neater way of achieving this using the method-chaining style of programming?

• objective-c Add to/Edit .plist file

  - by Dave

  Does writeToFile:atomically, add data to an existing .plist? Is it possible to modify a value in a .plist ? SHould the app be recompiled to take effect the change? I have a custom .plist list in my app. The structure is as below: <array> <dict> <key>Title</key> <string>MyTitle</string> <key>Measurement</key> <dict> <key>prop1</key> <real>28.86392</real> <key>prop2</key> <real>75.12451</real> </dict> <key>Distance</key> <dict> <key>prop3</key> <real>37.49229</real> <key>prop4</key> <real>58.64502</real> </dict> </dict> </array> The array tag holds multiple items with same structure. I need to add items to the existing .plist. Is that possible? I can write a UIView to do just that, if so. *EDIT - OK, I just tried to writetofile hoping it would atleast overwrite if not add to it. Strangely, the following code selects different path while reading and writing. NSString *rootPath = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0]; The .plist file is in my project. I can read from it. When I write to it, it is creating a .plist file and saving it in my /users/.../library/! Does this make sense to anyone?

• How should I provide access to this custom DAL?

  - by Casey

  I'm writing a custom DAL (VB.NET) for an ordering system project. I'd like to explain how it is coded now, and receive some alternate ideas to make coding against the DAL easier/more readable. The DAL is part of an n-tier (not n-layer) application, where each tier is in it's own assembly/DLL. The DAL consists of several classes that have specific behavior. For instance, there is an Order class that is responsible for retrieving and saving orders. Most of the classes have only two methods, a "Get" and a "Save," with multiple overloads for each. These classes are marked as Friend and are only visible to the DAL (which is in it's own assembly). In most cases, the DAL returns what I will call a "Data Object." This object is a class that contains only data and validation, and is located in a common assembly that both the BLL and DAL can read. To provide public access to the DAL, I currently have a static (module) class that has many shared members. A simplified version looks something like this: Public Class DAL Private Sub New End Sub Public Shared Function GetOrder(OrderID as String) as OrderData Dim OrderGetter as New OrderClass Return OrderGetter.GetOrder(OrderID) End Function End Class Friend Class OrderClass Friend Function GetOrder(OrderID as string) as OrderData End Function End Class The BLL would call for an order like this: DAL.GetOrder("123456") As you can imagine, this gets cumbersome very quickly. I'm mainly interested in structuring access to the DAL so that Intellisense is very intuitive. As it stands now, there are too many methods/functions in the DAL class with similar names. One idea I had is to break down the DAL into nested classes: Public Class DAL Private Sub New End Sub Public Class Orders Private Sub New End Sub Public Shared Function Get(OrderID as string) as OrderData End Function End Class End Class So the BLL would call like this: DAL.Orders.Get("12345") This cleans it up a bit, but it leaves a lot of classes that only have references to other classes, which I don't like for some reason. Without resorting to passing DB specific instructions (like where clauses) from BLL to DAL, what is the best or most common practice for providing a single point of access for the DAL?

• How to store wiki sites (vcs)

  - by Eugen

  Hello, as a personal project I am trying to write a wiki with the help of django. I'm a beginner when it comes to web development. I am at the (early) point where I need to decide how to store the wiki sites. I have three approaches in mind and would like to know your suggestion. Flat files I considered a flat file approach with a version control system like git or mercurial. Firstly, I would have some example wikis to look at like http://hatta.sheep.art.pl/. Secondly, the vcs would probably deal with editing conflicts and keeping the edit history, so I would not have to reinvent the wheel. And thirdly, I could probably easily clone the wiki repository, so I (or for that matter others) can have an offline copy of the wiki. On the other hand, as far as I know, I can not use django models with flat files. Then, if I wanted to add fields to a wiki site, like a category, I would need to somehow keep a reference to that flat file in order to associate the fields in the database with the flat file. Besides, I don't know if it is a good idea to have all the wiki sites in one repository. I imagine it is more natural to have kind of like a repository per wiki site resp. file. Last but not least, I'm not sure, but I think using flat files would limit my deploying capabilities because web hosts maybe don't allow creating files (I'm thinking, for example, of Google App Engine) Storing in a database By storing the wiki sites in the database I can utilize django models and associate arbitrary fields with the wiki site. I probably would also have an easier life deploying the wiki. But I would not get vcs features like history and conflict resolving per se. I searched for django-extensions to help me and I found django-reversion. However, I do not fully understand if it fit my needs. Does it track model changes like for example if I change the django model file, or does it track the content of the models (which would fit my need). Plus, I do not see if django reversion would help me with edit conflicts. Storing a vcs repository in a database field This would be my ideal solution. It would combine the advantages of both previous approaches without the disadvantages. That is; I would have vcs features but I would save the wiki sites in a database. The problem is: I have no idea how feasible that is. I just imagine saving a wiki site/source together with a git/mercurial repository in a database field. Yet, I somehow doubt database fields work like that. So, I'm open for any other approaches but this is what I came up with. Also, if you're interested, you can find the crappy early test I'm working on here http://github.com/eugenkiss/instantwiki-test

• problem with filtering the dropdownlist in scroll window

  - by Rahul

  Hi all, Problem with filtering Dropdown list. The scenario is : in scroll window there are two fields Document types and type id: Document type is Dropdown list: As per document type selection type id look should display the values. For ex. If I select quote type from document type and if I open type id look up it should display only quotation in the look window. It should work for all the values of document type drop down list values. Its working fine. The item in the document types are: Quote, Order, Invoice, Return, BackOrder. The problem is after saving the data when I am displaying the same record in scroll window, suppose after displaying document type is QUOTE and document id is QTOARD, and in this position I am changing the document type from dropdown QUOTE to ORDER at this time warning message should c ome this range entered is in valid. Because in database table there is no document QTOARD for ORDER type. The same should work for all the condition. The table name is SOP_ID_Setp and key is SOP Type and DocumentID. For that I have written the Stored procedure : create procedure DocTypeFilter @DocumentType as int, @DocumentID as varchar(30) as --declare --@documentype int, --@documentID varchar(30), select * from sop40200 where soptype=@DocumentType and docid=@DocumentID and I have called this SP in Dropdownlist change event. local long retcode; range clear table SOP_ID_SETP; clear field 'SOP Type' of table SOP_ID_SETP; clear field 'Document ID' of table SOP_ID_SETP; range start table SOP_ID_SETP; fill field 'SOP Type' of table SOP_ID_SETP; fill field 'Document ID' of table SOP_ID_SETP; range end table SOP_ID_SETP; if err()=OKAY then call DocTypeFilter,retcode,'Document Type' of window 'Is_Document Type Site_Scroll','Document ID' of window 'Is_Document Type Site_Scroll'; else warning "The range entered is invalid"; clear window 'Is_Document Type Site_Scroll'; fill window 'Is_Document Type Site_Scroll' table is_sop_site_line_temp; end if; Above code not giving the expected output any help pls.

• General Questions on setting up Subversion (w/Netbeans) and web development workflow.

  - by Roeland

  Hey guys, I am web developer who currently works mostly on his own but, some projects require outside coding help (my brother.) Anyway, after running in to the problem of "working on the same files" and "saving over each others edits" I decided to research ways to avoid this. Through the help of stackoverflow I decided on subversion. My setup is the following: A windows 2008 server with a clean install. My desktop which is on the local network of the server. Then my brothers desktop which is at his house, not on lan. We both prefer to use netbeans for development. My Questions: How do we set this thing up correctly and most optimally. Here is my current setup and work flow. dev site: in the past I just created sub domains with my web host for test sites (company1.bythepixel.com, company2.bythepixel.com), and editted those sites with netbeans set up having remote sources (ftp). how do i set up my netbeans now? should I set it up with remote sources? I guess I may need to set up a web server on my local server. I'm just not sure of the work flow. When i hit save in netbeans.. will it update the repository.. then do i need to update the site from the repository somehow? live site: when going live, i would just copy all the files from the dev site into the live site. from what i gather i should be able to update the site from the dev repository? Currently I am toying with virtualsvn server (http://www.visualsvn.com/server/) on my local server. It looks like it is set up to use the http protocol. Is there advantages to this or should I consider something that does the file//. Do you recommend any other subversion software that would run on my 2008 box? how will my brother connect? should i set up a permanent vpn from his house to mine? suggestions? (not that important) how do I deal with databases, there anyway to do subversion on database? I know I have a lot of questions and I am trying to read / make sense of the free online subversion book, but its all so overwhelming! Wish there was a small subversion for dummies guide :)

• Unable to verify body hash for DKIM

  - by Joshua

  I'm writing a C# DKIM validator and have come across a problem that I cannot solve. Right now I am working on calculating the body hash, as described in Section 3.7 Computing the Message Hashes. I am working with emails that I have dumped using a modified version of EdgeTransportAsyncLogging sample in the Exchange 2010 Transport Agent SDK. Instead of converting the emails when saving, it just opens a file based on the MessageID and dumps the raw data to disk. I am able to successfully compute the body hash of the sample email provided in Section A.2 using the following code: SHA256Managed hasher = new SHA256Managed(); ASCIIEncoding asciiEncoding = new ASCIIEncoding(); string rawFullMessage = File.ReadAllText(@"C:\Repositories\Sample-A.2.txt"); string headerDelimiter = "\r\n\r\n"; int headerEnd = rawFullMessage.IndexOf(headerDelimiter); string header = rawFullMessage.Substring(0, headerEnd); string body = rawFullMessage.Substring(headerEnd + headerDelimiter.Length); byte[] bodyBytes = asciiEncoding.GetBytes(body); byte[] bodyHash = hasher.ComputeHash(bodyBytes); string bodyBase64 = Convert.ToBase64String(bodyHash); string expectedBase64 = "2jUSOH9NhtVGCQWNr9BrIAPreKQjO6Sn7XIkfJVOzv8="; Console.WriteLine("Expected hash: {1}{0}Computed hash: {2}{0}Are equal: {3}", Environment.NewLine, expectedBase64, bodyBase64, expectedBase64 == bodyBase64); The output from the above code is: Expected hash: 2jUSOH9NhtVGCQWNr9BrIAPreKQjO6Sn7XIkfJVOzv8= Computed hash: 2jUSOH9NhtVGCQWNr9BrIAPreKQjO6Sn7XIkfJVOzv8= Are equal: True Now, most emails come across with the c=relaxed/relaxed setting, which requires you to do some work on the body and header before hashing and verifying. And while I was working on it (failing to get it to work) I finally came across a message with c=simple/simple which means that you process the whole body as is minus any empty CRLF at the end of the body. (Really, the rules for Body Canonicalization are quite ... simple.) Here is the real DKIM email with a signature using the simple algorithm (with only unneeded headers cleaned up). Now, using the above code and updating the expectedBase64 hash I get the following results: Expected hash: VnGg12/s7xH3BraeN5LiiN+I2Ul/db5/jZYYgt4wEIw= Computed hash: ISNNtgnFZxmW6iuey/3Qql5u6nflKPTke4sMXWMxNUw= Are equal: False The expected hash is the value from the bh= field of the DKIM-Signature header. Now, the file used in the second test is a direct raw output from the Exchange 2010 Transport Agent. If so inclined, you can view the modified EdgeTransportLogging.txt. At this point, no matter how I modify the second email, changing the start position or number of CRLF at the end of the file I cannot get the files to match. What worries me is that I have been unable to validate any body hash so far (simple or relaxed) and that it may not be feasible to process DKIM through Exchange 2010.
