  • MVC2 Controller is passed a null object as a parameter

    - by Steve Wright
    I am having an issue with a controller getting a null object as a parameter: [HttpGet] public ActionResult Login() { return View(); } [HttpPost] public ActionResult Login(LoginViewData userLogin) { Assert.IsNotNull(userLogin); // FAILS if (ModelState.IsValid) { } return View(userLogin); } The LoginViewData is being passed as null when the HttpPost is called: Using MvcContrib.FluentHtml: <h2>Login to your Account</h2> <div id="contact" class="rounded-10"> <%using (Html.BeginForm()) { %> <fieldset> <ol> <li> <%= this.TextBox(f=>f.UserLogin).Label("Name: ", "name") %> <%= Html.ValidationMessageFor(m => m.UserLogin) %> </li> <li> <%= this.Password(u => u.UserPassword).Label("Password:", "name") %> <%= Html.ValidationMessageFor(m => m.UserPassword) %> </li> <li> <%= this.CheckBox(f => f.RememberMe).LabelAfter("Remember Me")%> </li> <li> <label for="submit" class="name">&nbsp;</label> <%= this.SubmitButton("Login")%> </li> </ol> </fieldset> <% } %> <p>If you forgot your user name or password, please use the Password Retrieval Form.</p> </div> The view inherits from MvcContrib.FluentHtml.ModelViewPage and is strongly typed against the LoginViewData object: public class LoginViewData { [Required] [DisplayName("User Login")] public string UserLogin { get; set; } [Required] [DisplayName("Password")] public string UserPassword { get; set; } [DisplayName("Remember Me?")] public bool RememberMe { get; set; } } Any ideas on why this would be happening? UPDATE I rebuilt the web project from scratch and that fixed it. I am still concerned why it happened.

  • Chrome Extension - Cross-Origin XMLHttpRequest - Returning HTML/JSON

    - by Tyler
    Hi everyone, I hope you can help me :) I've created a Chrome extension (my first one) and I'm having some difficulty auto-populating a <select> with <option> that are being returned. the default_popup page is index.htm. I have two <select> (listboxes? can't remember the name) boxes. When a user first clicks the extension, it performs a XMLHttpRequest to a php script and get's a list of names from a MySQL database. It returns (onLoad) the list in the form of: <option>blah</option> When a user selects an option from the first listbox/select, it performs another XMLHttpRequest and auto-populates the second listbox/select. Then when a user selects an option from the second listbox it will eventually populate a few details further down the page. I've been testing by just running the index.htm file and seeing if just the code works correctly, which it does. However when trying to view it from the extension, it doesn't work. The onLoad doesn't fill in the first listbox, and selecting an option (one that I typed in the box for testing purposes) from the first listbox doesn't populate the second listbox. I thought maybe it was a permissions error, so I tried adding the domain to the manifest.json file; but I appear to be getting an error in the manifest.json file after doing so. In my default_popup (index.htm) file I have this script for my XMLHttpRequest: <script type="text/javascript"> function getClient(str,type) { if (str=="") { document.getElementById(type).innerHTML=""; return; } if (window.XMLHttpRequest) {// code for IE7+, Firefox, Chrome, Opera, Safari xmlhttp=new XMLHttpRequest(); } else {// code for IE6, IE5 xmlhttp=new ActiveXObject("Microsoft.XMLHTTP"); } xmlhttp.onreadystatechange=function() { if (xmlhttp.readyState==4 && xmlhttp.status==200) { document.getElementById(type).innerHTML=xmlhttp.responseText; } } xmlhttp.open("GET","http://(domain removed)/Extension/getInfo.php?q="+type+"&c="+str,true,"user","pass"); xmlhttp.send(); } </script> This is what my manifest.json file looks like: { "name": "Client Center Lite", "version": "1.0", "description": "blah", "browser_action": { "default_icon": "images/icon_19.png", "default_popup": "index.htm", "default_title": "Client Center Lite" }, "icons":{ "128":"images/icon_128.png" } "permissions": { "http://(domain removed)/" }, } Am I doing this correctly? The point of the extension is to be able to quickly view client details. The extension will only be given to employees locally in a .crx file, and not distributed online. The domain I am accessing through the PHP/MySQL is accessible from the web, but I'm currently using localhost in my mysql_connect string. Do I need to be returning the <option> elements encoded as JSON? If so, I'm completely cluesless as how to do that.

  • IDataServiceMetadataProvider - Entities dont show up in $metadata.

    - by TomTom
    I am trying to write our own RIA services provider to expose data from a server that I access via ODBC. I follow th eguidelines set out at http://blogs.msdn.com/alexj/archive/2010/03/02/creating-a-data-service-provider-part-9-un-typed.aspx I have written our own IDataServiceMetadataProvider / IDataServiceQueryProvider pair and get no errors on what i do. I am putting in a resource set like this: ResourceType tableType = new ResourceType( typeof(Dictionary<string, object>), ResourceTypeKind.EntityType, null, "Martini", table_name, false ); tableType.CanReflectOnInstanceType = false; var prodKey = new ResourceProperty( "Key", ResourcePropertyKind.Key | ResourcePropertyKind.Primitive, ResourceType.GetPrimitiveResourceType(typeof(int)) ); prodKey.CanReflectOnInstanceTypeProperty = false; tableType.AddProperty(prodKey); var prodName = new ResourceProperty( "Name", ResourcePropertyKind.Primitive, ResourceType.GetPrimitiveResourceType(typeof(string)) ); prodName.CanReflectOnInstanceTypeProperty = false; tableType.AddProperty(prodName); _MetaDataProvider.AddResourceType(tableType); _MetaDataProvider.AddResourceSet(new ResourceSet(table_name, tableType)); I see the requests coming in for enumerating the resource sets. I check them there in a breakpoint, and the resource set and the type is there, with all properties. Still, the output I get is: <?xml version="1.0" encoding="utf-8" standalone="yes" ?> - <service xml:base="http://localhost:2377/MartiniData.svc/" xmlns:atom="http://www.w3.org/2005/Atom" xmlns:app="http://www.w3.org/2007/app" xmlns="http://www.w3.org/2007/app"> - <workspace> <atom:title>Default</atom:title> </workspace> </service> And for the $metadata version: <?xml version="1.0" encoding="utf-8" standalone="yes" ?> - <edmx:Edmx Version="1.0" xmlns:edmx="http://schemas.microsoft.com/ado/2007/06/edmx"> - <edmx:DataServices xmlns:m="http://schemas.microsoft.com/ado/2007/08/dataservices/metadata" m:DataServiceVersion="1.0"> - <Schema Namespace="Martini" xmlns:d="http://schemas.microsoft.com/ado/2007/08/dataservices" xmlns:m="http://schemas.microsoft.com/ado/2007/08/dataservices/metadata" xmlns="http://schemas.microsoft.com/ado/2007/05/edm"> <EntityContainer Name="Martini" m:IsDefaultEntityContainer="true" /> </Schema> </edmx:DataServices> </edmx:Edmx> The actual metadata for the types never shows up, no error is shown. pretty frustrating. Anyone any idea?

  • Retrieving Encrypted Rich Text file and showing it in a RichTextBox C#

    - by Ranhiru
    OK, my need here is to save whatever typed in the rich text box to a file, encrypted, and also retrieve the text from the file again and show it back on the rich textbox. Here is my save code. private void cmdSave_Click(object sender, EventArgs e) { FileStream fs = new FileStream(filePath, FileMode.Create, FileAccess.Write); AesCryptoServiceProvider aes = new AesCryptoServiceProvider(); aes.GenerateIV(); aes.GenerateKey(); aes.Mode = CipherMode.CBC; TextWriter twKey = new StreamWriter("key"); twKey.Write(ASCIIEncoding.ASCII.GetString(aes.Key)); twKey.Close(); TextWriter twIV = new StreamWriter("IV"); twIV.Write(ASCIIEncoding.ASCII.GetString(aes.IV)); twIV.Close(); ICryptoTransform aesEncrypt = aes.CreateEncryptor(); CryptoStream cryptoStream = new CryptoStream(fs, aesEncrypt, CryptoStreamMode.Write); richTextBox1.SaveFile(cryptoStream, RichTextBoxStreamType.RichText); } I know the security consequences of saving the key and iv in a file but this just for testing :) Well, the saving part works fine which means no exceptions... The file is created in filePath and the key and IV files are created fine too... OK now for retrieving part where I am stuck :S private void cmdOpen_Click(object sender, EventArgs e) { OpenFileDialog openFile = new OpenFileDialog(); openFile.ShowDialog(); FileStream openRTF = new FileStream(openFile.FileName, FileMode.Open, FileAccess.Read); AesCryptoServiceProvider aes = new AesCryptoServiceProvider(); TextReader trKey = new StreamReader("key"); byte[] AesKey = ASCIIEncoding.ASCII.GetBytes(trKey.ReadLine()); TextReader trIV = new StreamReader("IV"); byte[] AesIV = ASCIIEncoding.ASCII.GetBytes(trIV.ReadLine()); aes.Key = AesKey; aes.IV = AesIV; ICryptoTransform aesDecrypt = aes.CreateDecryptor(); CryptoStream cryptoStream = new CryptoStream(openRTF, aesDecrypt, CryptoStreamMode.Read); StreamReader fx = new StreamReader(cryptoStream); richTextBox1.Rtf = fx.ReadToEnd(); //richTextBox1.LoadFile(fx.BaseStream, RichTextBoxStreamType.RichText); } But the richTextBox1.Rtf = fx.ReadToEnd(); throws an cryptographic exception "Padding is invalid and cannot be removed." while richTextBox1.LoadFile(fx.BaseStream, RichTextBoxStreamType.RichText); throws an NotSupportedException "Stream does not support seeking." Any suggestions on what i can do to load the data from the encrypted file and show it in the rich text box?

  • Using embedded resources in Silverlight (4) - other cultures not being compiled

    - by Andrei Rinea
    I am having a bit of a hard time providing localized strings for the UI in a small Silverlight 4 application. Basically I've put a folder "Resources" and placed two resource files in it : Statuses.resx Statuses.ro.resx I do have an enum Statuses : public enum Statuses { None, Working } and a convertor : public class StatusToMessage : IValueConverter { public object Convert(object value, Type targetType, object parameter, CultureInfo culture) { if (!Enum.IsDefined(typeof(Status), value)) { throw new ArgumentOutOfRangeException("value"); } var x = Statuses.None; return Statuses.ResourceManager.GetString(((Status)value).ToString(), Thread.CurrentThread.CurrentUICulture); } public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture) { throw new NotImplementedException(); } } in the view I have a textblock : <TextBlock Grid.Column="3" Text="{Binding Status, Converter={StaticResource StatusToMessage}}" /> Upon view rendering the converter is called but no matter what the Thread.CurrentThread.CurrentUICulture is set it always returns the default culture value. Upon further inspection I took apart the XAP resulted file, taken the resulted DLL file to Reflector and inspected the embedded resources. It only contains the default resource!! Going back to the two resource files I am now inspecting their properties : Build action : Embedded Resource Copy to output directory : Do not copy Custom tool : ResXFileCodeGenerator Custom tool namespace : [empty] Both resource (.resx) files have these settings. The .Designer.cs resulted files are as follows : Statuses.Designer.cs : //------------------------------------------------------------------------------ // <auto-generated> // This code was generated by a tool. // Runtime Version:4.0.30319.1 // // Changes to this file may cause incorrect behavior and will be lost if // the code is regenerated. // </auto-generated> //------------------------------------------------------------------------------ namespace SilverlightApplication5.Resources { using System; /// <summary> /// A strongly-typed resource class, for looking up localized strings, etc. /// </summary> // This class was auto-generated by the StronglyTypedResourceBuilder // class via a tool like ResGen or Visual Studio. // To add or remove a member, edit your .ResX file then rerun ResGen // with the /str option, or rebuild your VS project. [global::System.CodeDom.Compiler.GeneratedCodeAttribute("System.Resources.Tools.StronglyTypedResourceBuilder", "4.0.0.0")] [global::System.Diagnostics.DebuggerNonUserCodeAttribute()] [global::System.Runtime.CompilerServices.CompilerGeneratedAttribute()] internal class Statuses { // ... yadda-yadda Statuses.ro.Designer.cs [empty] I've taken both files and put them in a console application and they behave as expected in it, not like in this silverlight application. What is wrong?

  • JavaScript: Doing some stuff right before the user exits the page

    - by Mike
    I have seen some questions here regarding what I want to achieve and have based what I have so far on those answer. But there is a slight misbehavior that is still irritating me. What I have is sort of a recovery feature. Whenever you are typing text, the client sends a sync request to the server every 45 seconds. It does 2 things. First, it extends the lease the client has on the record (only one person may edit at one time) for another 60 seconds. Second, it sends the text typed so far to the server in case the server crashes, internet connection fails, etc. In that case, the next time the user enters our application, the user is notified that something has gone wrong and that some text was recovered. Think of Microsoft or OpenOffice recovery whenever they crash! Of course, if the user leaves the page willingly, the user does not need to be notified and as a result, the recovery is deleted. I do that final request via a beforeunload event. Everything went fine until I was asked to make a final adjustment... The same behavior you have here at stack overflow when you exit the editor... a confirm dialogue. This works so far, BUT, the confirm dialogue is shown twice. Here is the code. The event if (local.sync.autosave_textelement) { window.onbeforeunload = exitConfirm; } The function function exitConfirm() { var local = Core; if (confirm('blub?')) { local.sync.autosave_destroy = true; sync(false); return true; } else { return false; } }; Some problem irrelevant clarifications: Core is a global Object that contains a lot of variables that are used everywhere. sync makes an ajax request. The values are based on the values that the Core.sync object contains. The parameter determines if the call should be async (default) or sync.

  • Trouble cross-referencing two XML child nodes in AS3

    - by Dwayne
    I am building a mini language translator out of XML nodes and Actionscript 3. I have my XML ready. It contains a series of nodes with two children in them. Here is a sample: <translations> <entry> <english>man</english> <cockney>geeza</cockney> </entry> <entry> <english>woman</english> <cockney>lily</cockney> </entry> </translations> The AS3 part consist of one input box named "textfield_txt" where the English word will be typed in. An output text field for the translation called "cockney_txt". Finally, one button to execute the translation called "generate_mc". The idea is to have actionscript look through the XML for key English words after the user types it in the "textfield", cross-freferences the children then returns the Cockney translation as a value. The trouble is, when I test it I get no response or error messages- it's completely silent. I'm not sure what I'm doing wrong. At present, I have setup a conditional statement to tell me whether the function works or not. The result is, no it's not! Here's the code below. I hope someone can help. Cheers! generate_mc.buttonMode=true; var English:String; var myXML:XML; var myLoader:URLLoader = new URLLoader(); myLoader.load(new URLRequest("Language.xml")); myLoader.addEventListener(Event.COMPLETE, processXML); function processXML(e:Event):void { myXML = new XML(e.target.data); } generate_mc.addEventListener(MouseEvent.CLICK, onClick); function onClick(event:MouseEvent) { English = textfield.text; cockney_txt.text = myXML.translations.entry.cockney; if(textfield.text.toLowerCase() == myXML.translations.entry.english.toLowerCase){ //return myXML.translations.entry.cockney; trace("success"); }else{ trace("try again!"); // ***I get this as a result } }

  • Wondering why DisplayName attribute is ignored in LabelFor on an overridden property

    - by Lasse Krantz
    Hi, today I got confused when doing a couple of <%=Html.LabelFor(m=>m.MyProperty)%> in ASP.NET MVC 2 and using the [DisplayName("Show this instead of MyProperty")] attribute from System.ComponentModel. As it turned out, when I put the attribute on an overridden property, LabelFor didn't seem to notice it. However, the [Required] attribute works fine on the overridden property, and the generated errormessage actually uses the DisplayNameAttribute. This is some trivial examplecode, the more realistic scenario is that I have a databasemodel separate from the viewmodel, but for convenience, I'd like to inherit from the databasemodel, add View-only properties and decorating the viewmodel with the attributes for the UI. public class POCOWithoutDataAnnotations { public virtual string PleaseOverrideMe { get; set; } } public class EditModel : POCOWithoutDataAnnotations { [Required] [DisplayName("This should be as label for please override me!")] public override string PleaseOverrideMe { get { return base.PleaseOverrideMe; } set { base.PleaseOverrideMe = value; } } [Required] [DisplayName("This property exists only in EditModel")] public string NonOverriddenProp { get; set; } } The strongly typed ViewPage<EditModel> contains: <div class="editor-label"> <%= Html.LabelFor(model => model.PleaseOverrideMe) %> </div> <div class="editor-field"> <%= Html.TextBoxFor(model => model.PleaseOverrideMe) %> <%= Html.ValidationMessageFor(model => model.PleaseOverrideMe) %> </div> <div class="editor-label"> <%= Html.LabelFor(model => model.NonOverriddenProp) %> </div> <div class="editor-field"> <%= Html.TextBoxFor(model => model.NonOverriddenProp) %> <%= Html.ValidationMessageFor(model => model.NonOverriddenProp) %> </div> The labels are then displayed as "PleaseOverrideMe" (not using the DisplayNameAttribute) and "This property exists only in EditModel" (using the DisplayNameAttribute) when viewing the page. If I post with empty values, triggering the validation with this ActionMethod: [HttpPost] public ActionResult Edit(EditModel model) { if (!ModelState.IsValid) return View(model); return View("Thanks"); } the <%= Html.ValidationMessageFor(model => model.PleaseOverrideMe) %> actually uses [DisplayName("This should be as label for please override me!")] attribute, and produces the default errortext "The This should be as label for please override me! field is required." Would some friendly soul shed some light on this?

  • About variadic templates

    - by chedi
    Hi, I'm currently experiencing with the new c++0x variadic templates, and it's quit fun, Although I have a question about the process of member instanciation. in this example, I'm trying to emulate the strongly typed enum with the possibility of choose a random valid strong enum (this is used for unit testing). #include<vector> #include<iostream> using namespace std; template<unsigned... values> struct sp_enum; /* this is the solution I found, declaring a globar var vector<unsigned> _data; and it work just fine */ template<> struct sp_enum<>{ static const unsigned _count = 0; static vector<unsigned> _data; }; vector<unsigned> sp_enum<>::_data; template<unsigned T, unsigned... values> struct sp_enum<T, values...> : private sp_enum<values...>{ static const unsigned _count = sp_enum<values...>::_count+1; static vector<unsigned> _data; sp_enum( ) : sp_enum<values...>(values...) {_data.push_back(T);} sp_enum(unsigned v ) {_data.push_back(v);} sp_enum(unsigned v, unsigned...) : sp_enum<values...>(values...) {_data.push_back(v);} }; template<unsigned T, unsigned... values> vector<unsigned> sp_enum<T, values...>::_data; int main(){ enum class t:unsigned{Default = 5, t1, t2}; sp_enum<t::Default, t::t1, t::t2> test; cout <<test._count << endl << test._data.size() << endl; for(auto i= test._data.rbegin();i != test._data.rend();++i){cout<< *i<< ":";} } the result I'm getting with this code is : 3 1 5: can someone point me what I'm messing here ???

  • handling NSStream events when using EASession in MonoTouch

    - by scotru
    Does anyone have an example of how to handle read and write NSStream events in Monotouch when working with accessories via EASession? It looks like there isn't a strongly typed delegate for this and I'm having trouble figuring out what selectors I need to handle on the delegates of my InputStream and OutputStream and what I actually need to do with each selector in order to properly fill and empty the buffers belonging to the EASession object. Basically, I'm trying to port Apple's EADemo app to Monotouch right now. Here's the Objective-C source that I think is relevant to this problem: / / asynchronous NSStream handleEvent method - (void)stream:(NSStream *)aStream handleEvent:(NSStreamEvent)eventCode { switch (eventCode) { case NSStreamEventNone: break; case NSStreamEventOpenCompleted: break; case NSStreamEventHasBytesAvailable: [self _readData]; break; case NSStreamEventHasSpaceAvailable: [self _writeData]; break; case NSStreamEventErrorOccurred: break; case NSStreamEventEndEncountered: break; default: break; } } / low level write method - write data to the accessory while there is space available and data to write - (void)_writeData { while (([[_session outputStream] hasSpaceAvailable]) && ([_writeData length] > 0)) { NSInteger bytesWritten = [[_session outputStream] write:[_writeData bytes] maxLength:[_writeData length]]; if (bytesWritten == -1) { NSLog(@"write error"); break; } else if (bytesWritten > 0) { [_writeData replaceBytesInRange:NSMakeRange(0, bytesWritten) withBytes:NULL length:0]; } } } // low level read method - read data while there is data and space available in the input buffer - (void)_readData { #define EAD_INPUT_BUFFER_SIZE 128 uint8_t buf[EAD_INPUT_BUFFER_SIZE]; while ([[_session inputStream] hasBytesAvailable]) { NSInteger bytesRead = [[_session inputStream] read:buf maxLength:EAD_INPUT_BUFFER_SIZE]; if (_readData == nil) { _readData = [[NSMutableData alloc] init]; } [_readData appendBytes:(void *)buf length:bytesRead]; //NSLog(@"read %d bytes from input stream", bytesRead); } [[NSNotificationCenter defaultCenter] postNotificationName:EADSessionDataReceivedNotification object:self userInfo:nil]; } I'd also appreciate any architectural recommendations on how to best implement this in monotouch. For example, in the Objective C implementation these functions are not contained in any class--but in Monotouch would it make sense to make them members of my

  • How can I include additional markup within a 'Content' inner property of an ASP.Net WebControl?

    - by GenericTypeTea
    I've searched the site and I cannot find a solution for my problem, so apologies if it's already been answered (I'm sure someone must have asked this before). I have written a jQuery Popup window that I've packaged up as a WebControl and IScriptControl. The last step is to be able to write the markup within the tags of my control. I've used the InnerProperty attribute a few times, but only for including lists of strongly typed classes. Here's my property on the WebControl: [PersistenceMode(PersistenceMode.InnerProperty)] [DesignerSerializationVisibility(DesignerSerializationVisibility.Content)] public something??? Content { get { if (_content == null) { _content = new something???(); } return _content; } } private something??? _content; Here's the HTML Markup of what I'm after: <ctr:WebPopup runat="server" ID="win_Test" Hidden="false" Width="100px" Height="100px" Modal="true" WindowCaption="Test Window" CssClass="window"> <Content> <div style="display:none;"> <asp:Button runat="server" ID="Button1" OnClick="Button1_Click" /> </div> <%--Etc--%> <%--Etc--%> </Content> </ctr:WebPopup> Unfortunately I don't know what type my Content property should be. I basically need to replicate the UpdatePanel's ContentTemplate. EDIT: So the following allows a Template container to be automatically created, but no controls show up, what's wrong with what I'm doing? [PersistenceMode(PersistenceMode.InnerProperty)] [DesignerSerializationVisibility(DesignerSerializationVisibility.Content)] public ITemplate Content { get { return _content; } set { _content = value; } } private ITemplate _content; EDIT2: Overriding the CreateChildControls allows the controls within the ITemplate to be rendered: protected override void CreateChildControls() { if (this.Content != null) { this.Controls.Clear(); this.Content.InstantiateIn(this); } base.CreateChildControls(); } Unfortunately I cannot now access the controls within the ITemplate from the codebehind file on the file. I.e. if I put a button within my mark as so: <ctr:WebPopup runat="server" ID="win_StatusFilter"> <Content> <asp:Button runat="server" ID="btn_Test" Text="Cannot access this from code behind?" /> </Content> </ctr:WebPopup> I then cannot access btn_Test from the code behind: protected void Page_Load(object sender, EventArgs e) { btn_Test.Text = "btn_Test is not present in Intellisense and is not accessible to the page. It does, however, render correctly."; }

  • C# Spell checker Problem

    I've incorporated spell check into my win forms C# project. This is my code. public void CheckSpelling() { try { // declare local variables to track error count // and information int SpellingErrors = 0; string ErrorCountMessage = string.Empty; // create an instance of a word application Microsoft.Office.Interop.Word.Application WordApp = new Microsoft.Office.Interop.Word.Application(); // hide the MS Word document during the spellcheck //WordApp.WindowState = WdWindowState.wdWindowStateMinimize; // check for zero length content in text area if (this.Text.Length > 0) { WordApp.Visible = false; // create an instance of a word document _Document WordDoc = WordApp.Documents.Add(ref emptyItem, ref emptyItem, ref emptyItem, ref oFalse); // load the content written into the word doc WordDoc.Words.First.InsertBefore(this.Text); // collect errors form new temporary document set to contain // the content of this control Microsoft.Office.Interop.Word.ProofreadingErrors docErrors = WordDoc.SpellingErrors; SpellingErrors = docErrors.Count; // execute spell check; assumes no custom dictionaries WordDoc.CheckSpelling(ref oNothing, ref oIgnoreUpperCase, ref oAlwaysSuggest, ref oNothing, ref oNothing, ref oNothing, ref oNothing, ref oNothing, ref oNothing, ref oNothing, ref oNothing, ref oNothing); // format a string to contain a report of the errors detected ErrorCountMessage = "Spell check complete; errors detected: " + SpellingErrors; // return corrected text to control's text area object first = 0; object last = WordDoc.Characters.Count - 1; this.Text = WordDoc.Range(ref first, ref last).Text; } else { // if nothing was typed into the control, abort and inform user ErrorCountMessage = "Unable to spell check an empty text box."; } WordApp.Quit(ref oFalse, ref emptyItem, ref emptyItem); System.Runtime.InteropServices.Marshal.ReleaseComObject(WordApp); // return report on errors corrected // - could either display from the control or change this to // - return a string which the caller could use as desired. // MessageBox.Show(ErrorCountMessage, "Finished Spelling Check"); } catch (Exception e) { MessageBox.Show(e.ToString()); } } The spell checker works well, the only problem is when I try to move the spell checker the main form blurs up for some reason. Also when I close the spell checker the main form is back to normal. It seems like it is opening up Microsoft word then hiding the window, only allowing the spell checker to be seen. Please help.

  • How to merge jquery autocomplete and fcbkListSelection functionality?

    - by Ben
    Initial caveat: I am a newbie to jquery and javascript. I started using the autocomplete jquery plugin recently from bassistance.de. Yesterday, I found the fcbkListSelection plugin (http://www.emposha.com/javascript/fcbklistselection-like-facebook-friends-selector.html) and am using it to include a selector in my application. What I now want to do is to merge the 2 pieces of functionality since there are lots of items in my selector list. To be more specific, I want to put a "Filter by Name" text box above the facebook list selection object in my html. When the user types a few characters into the "Filter by Name" text box, I want the items in the Facebook list selector to only show the items that contain the typed characters -- kind of like what autocomplete does already, but rather than the results showing below the text input box, I want them to dynamically update the facebook list object. Is this possible and relatively straightforward? If so, can somebody please describe how to do it? If not, is there an easier way to approach this? Thanks! OK, to Spencer Ruport's comment, I guess I may have a more specific question already. Below is the current Javascript in my HTML file (angle brackets represent Django tags). #suggest1 and #fcbklist both do their separate pieces, but how do I get them to talk to each other? Do I need to further write javascript in my HTML file, or do I need to customize the guts of the plugins' .js? Does this help elaborate? $(document).ready(function() { var names = []; var count = 0; {% for a, b, c in friends_for_picker %} names[count] = "{{ b }}"; count = count+1; {% endfor %} function findValueCallback(event, data, formatted) { $("<li>").html( !data ? "No match!" : "Selected: " + formatted).appendTo("#result"); } function formatItem(row) { return row[0] + " (<strong>id: " + row[1] + "</strong>)"; } function formatResult(row) { return row[0].replace(/(<.+?>)/gi, ''); } $("#suggest1").autocomplete(names, { multiple: true, mustMatch: false, autoFill: true, matchContains: true, }); //id(ul id),width,height(element height),row(elements in row) $.fcbkListSelection("#fcbklist","575","50","4"); });

  • get_or_create generic relations in Django & python debugging in general

    - by rabidpebble
    I ran the code to create the generically related objects from this demo: http://www.djangoproject.com/documentation/models/generic_relations/ Everything is good intially: >>> bacon.tags.create(tag="fatty") <TaggedItem: fatty> >>> tag, newtag = bacon.tags.get_or_create(tag="fatty") >>> tag <TaggedItem: fatty> >>> newtag False But then the use case that I'm interested in for my app: >>> tag, newtag = bacon.tags.get_or_create(tag="wholesome") Traceback (most recent call last): File "<console>", line 1, in <module> File "/usr/local/lib/python2.6/dist-packages/django/db/models/manager.py", line 123, in get_or_create return self.get_query_set().get_or_create(**kwargs) File "/usr/local/lib/python2.6/dist-packages/django/db/models/query.py", line 343, in get_or_create raise e IntegrityError: app_taggeditem.content_type_id may not be NULL I tried a bunch of random things after looking at other code: >>> tag, newtag = bacon.tags.get_or_create(tag="wholesome", content_type=TaggedItem) ValueError: Cannot assign "<class 'generics.app.models.TaggedItem'>": "TaggedItem.content_type" must be a "ContentType" instance. or: >>> tag, newtag = bacon.tags.get_or_create(tag="wholesome", content_type=TaggedItem.content_type) InterfaceError: Error binding parameter 3 - probably unsupported type. etc. I'm sure somebody can give me the correct syntax, but the real problem here is that I have no idea what is going on. I have developed in strongly typed languages for over ten years (x86 assembly, C++ and C#) but am new to Python. I find it really difficult to follow what is going on in Python when things like this break. In the languages I mentioned previously it's fairly straightforward to figure things like this out -- check the method signature and check your parameters. Looking at the Django documentation for half an hour left me just as lost. Looking at the source for get_or_create(self, **kwargs) didn't help either since there is no method signature and the code appears very generic. A next step would be to debug the method and try to figure out what is happening, but this seems a bit extreme... I seem to be missing some fundamental operating principle here... what is it? How do I resolve issues like this on my own in the future?

  • Javascript InnerHTML Erases Data In Form Elements

It should leave the data in form elements

  • Problems with contenteditable in Firefox

    - by Jonathan
    Hello, I am working on a Javascript WYSIWYG editor in Firefox. I am using a div with the contenteditable attribute set to true in order to accomplish this (I cannot use a contenteditable iframe for this particular project). This contenteditable div is nested in another div that is not contenteditable. I am encountering the following two problems when using execCommand to apply formatting, including font style and size, as well as bold, italic, and underline: When all text in the div is selected, execCommand simply does not work. execCommand works fine when only part of the text is selected, but does nothing when all of the text is selected. Applying formatting with no text selected yields unexpected results. For example, when calling execCommand('bold') with no text selected and then typing results in bold text being typed until a spacebar is inserted, at which point the bold formatting is lost (until another space is inserted, interestingly enough; then the text becomes bold again). To see what I mean, please try running the following HTML code in Firefox 3: <html> <head><title></title></head> <body> <button onClick="execCommand('bold', false, null);">Bold</button> <div style="width: 300px; border: 1px solid #000000;"> <div contenteditable="true">Some editable text</div> </div> </body> </html> Please try the following: Select the word "Some" only. Click the Bold button. This will make the text bold, as expected. Select the entire phrase "Some editable text" (either manually or using CTRL-A). Click the Bold button. Nothing happens. This demonstrates the first bug shown above. Hit the backspace key to clear the div. Click the Bold button and begin typing. Type a few words with spaces. This will demonstrate the second bug. Any ideas on what could be causing these problems and how to work around them would be greatly appreciated!

  • Chaining multiple ShellExecute calls

    - by IVlad
    Consider the following code and its executable - runner.exe: #include <iostream> #include <string> #include <windows.h> using namespace std; int main(int argc, char *argv[]) { SHELLEXECUTEINFO shExecInfo; shExecInfo.cbSize = sizeof(SHELLEXECUTEINFO); shExecInfo.fMask = NULL; shExecInfo.hwnd = NULL; shExecInfo.lpVerb = "open"; shExecInfo.lpFile = argv[1]; string Params = ""; for ( int i = 2; i < argc; ++i ) Params += argv[i] + ' '; shExecInfo.lpParameters = Params.c_str(); shExecInfo.lpDirectory = NULL; shExecInfo.nShow = SW_SHOWNORMAL; shExecInfo.hInstApp = NULL; ShellExecuteEx(&shExecInfo); return 0; } These two batch files both do what they're supposed to, which is run notepad.exe and run notepad.exe and tell it to try to open test.txt: 1. runner.exe notepad.exe 2. runner.exe notepad.exe test.txt Now, consider this batch file: 3. runner.exe runner.exe notepad.exe This one should run runner.exe and send notepad.exe as one of its command line arguments, shouldn't it? Then, that second instance of runner.exe should run notepad.exe - which doesn't happen, I get a "Windows cannot find 'am'. Make sure you typed the name correctly, and then try again" error. If I print the argc argument, it's 14 for the second instance of runner.exe, and they are all weird stuff like Files\Microsoft, SQL, Files\Common and so on. I can't figure out why this happens. I want to be able to string as many runner.exe calls using command line arguments as possible, or at least 2. How can I do that? I am using Windows 7 if that makes a difference.

  • Why always fires OnFailure when return View() to Ajax Form ?

    - by Wahid Bitar
    I'm trying to make a log-in log-off with Ajax supported. I made some logic in my controller to sign the user in and then return simple partial containing welcome message and log-Off ActionLink my Action method looks like this : public ActionResult LogOn(LogOnModel model, string returnUrl) { if (ModelState.IsValid) { if (MembershipService.ValidateUser(model.UserName, model.Password)) { FormsService.SignIn(model.UserName, model.RememberMe); if (Request.IsAjaxRequest()) { //HERE IS THE PROBLEM :( return View("LogedInForm"); } else { if (!String.IsNullOrEmpty(returnUrl)) return Redirect(returnUrl); else return RedirectToAction("Index", "Home"); } } else { ModelState.AddModelError("", "The user name or password provided is incorrect."); if (Request.IsAjaxRequest()) { return Content("There were an error !"); } } } return View(model); } and I'm trying to return this simple partial : Welcome <b><%= Html.Encode(Model.UserName)%></b>! <%= Html.ActionLink("Log Off", "LogOff", "Account") %> and of-course the two partial are strongly-typed to LogOnModel. But if i returned View("PartialName") i always get OnFailure with status code 500. While if i returned Content("My Message") everything is going right. so please tell me why i always get this "StatusCode = 500" ??. where is the big mistake ??. By the way in my Site MasterPage i rendered partial to show long-on simple form this partial looks like this : <script type="text/javascript"> function ShowErrorMessage(ajaxContext) { var response = ajaxContext.get_response(); var statusCode = response.get_statusCode(); alert("Sorry, the request failed with status code " + statusCode); } function ShowSuccessMessage() { alert("Hey everything is OK!"); } </script> <div id="logedInDiv"> </div> <% using (Ajax.BeginForm("LogOn", "Account", new AjaxOptions { UpdateTargetId = "logedInDiv", InsertionMode = InsertionMode.Replace, OnSuccess = "ShowSuccessMessage", OnFailure = "ShowErrorMessage" })) { %> <%= Html.TextBoxFor(m => m.UserName)%> <%= Html.PasswordFor(m => m.Password)%> <%= Html.CheckBoxFor(m => m.RememberMe)%> <input type="submit" value="Log On" /> < <% } %>

  • What is the best way to read and write cXML documents in C# ?

    - by tetranz
    I know this is a vague open ended question. I'm hoping to get some general direction. I need to add cXML punchout to an ASP.NET C# site / application. This is replacing something that I wrote years ago in ColdFusion. I'm a reasonably experienced C# developer but I haven't done much with XML. There seems to be lots of different options for processing XML in .NET. Here's the open ended question: Assuming that I have an XML document in some form, eg a file or a string, what is the best way to read it into my code? I want to get the data and then query databases etc. The cXML document size and our traffic volumes are easily small enough so that loading the a cXML document into memory is not a problem. Should I: 1) Manually build classes based on the dtd and use the XML Serializer? 2) Use a tool to generate classes. There are sample cXML files downloadable from Ariba.com. I tried xsd.exe to generate an xsd and then xsd.exe /c to generate classes. When I try to deserialize I get errors because there seems to be "confusion" around whether some elements should be single values or arrays. I tried the CodeXS online tool but that gives errors in it's log and errors if I try to deserialize a sample document. 2) Create a dataset and ReadXml()? 3) Create a typed dataset and ReadXml()? 4) Use Linq to XML. I often use Linq to Objects so I'm familiar with Linq in general but I'm struggling to see what it gives me in this situation. 5) Some other means. I guess I need to improve my understanding of XML in general but even so ... am I missing some obvious way of doing this? In the old ColdFusion site I found a free component ("tag") which basically ignored any schema and read the XML into a "structure" which is essentially a series of nested hash tables which was then easy to read in code. That was probably quite sloppy but it worked. I also need to generate XML files from my C# objects. Maybe Linq to XML will be good for that. I could start with a default "template" document and manipulate it before saving. Thanks for any pointers ...

  • What is a good platform for building a game framework targetting both web and native languages?

    - by fuzzyTew
    I would like to develop (or find, if one is already in development) a framework with support for accelerated graphics and sound built on a system flexible enough to compile to the following: native ppc/x86/x86_64/arm binaries or a language which compiles to them javascript actionscript bytecode or a language which compiles to it (actionscript 3, haxe) optionally java I imagine, for example, creating an API where I can open windows and make OpenGL-like calls and the framework maps this in a relatively efficient manner to either WebGL with a canvas object, 3d graphics in Flash, OpenGL ES 2 with EGL, or desktop OpenGL in an X11, Windows, or Cocoa window. I have so far looked into these avenues: Building the game library in haXe Pros: Targets exist for php, javascript, actionscript bytecode, c++ High level, object oriented language Cons: No support for finally{} blocks or destructors, making resource cleanup difficult C++ target does not allow room for producing highly optimized libraries -- the foreign function interface requires all primitive types be boxed in a wrapper object, as if writing bindings for a scripting language; these feel unideal for real-time graphics and audio, especially exporting low-level functions. Doesn't seem quite yet mature Using the C preprocessor to create a translator, writing programs entirely with macros Pros: CPP is widespread and simple to use Cons: This is an arduous task and probably the wrong tool for the job CPP implementations differ widely in support for features (e.g. xcode cpp has no variadic macros despite claiming C99 compliance) There is little-to-no room for optimization in this route Using llvm's support for multiple backends to target c/c++ to web languages Pros: Can code in c/c++ LLVM is a very mature highly optimizing compiler performing e.g. global inlining Targets exist for actionscript (alchemy) and javascript (emscripten) Cons: Actionscript target is closed source, unmaintained, and buggy. Javascript targets do not use features of HTML5 for appropriate optimization (e.g. linear memory with typed arrays) and are immature An LLVM target must convert from low-level bytecode, so high-level constructs are lost and bloated unreadable code is created from translating individual instructions, which may be more difficult for an unprepared JIT to optimize. "jump" instructions cause problems for languages with no "goto" statements. Using libclang to write a translator from C/C++ to web languages Pros: A beautiful parsing library providing easy access to the code structure Can code in C/C++ Has sponsored developer effort from Apple Cons: Incomplete; current feature set targets IDEs. Basic operators are unexposed and must be manually parsed from the returned AST element to be identified. Translating code prior to compilation may forgo optimizations assumed in c/c++ such as inlining. Creating new code generators for clang to translate into web languages Pros: Can code in C/C++ as libclang Cons: There is no API; code structure is unstable A much larger job than using libclang; the innards of clang are complex Building the game library in Common Lisp Pros: Flexible, ancient, well-developed language Extensive introspection should ease writing translators Translators exist for at least javascript Cons: Unfamiliar language No standardized library functions, widely varying implementations Which of these avenues should I pursue? Do you know of any others, or any systems that might be useful? Does a general project like this exist somewhere already? Thank you for any input.

  • Reading POST data from html form sent to serversocket.

    - by user32167
    i try to write simplest possible server app in Java, displaying html form with textarea input, which after submitting gives me possibility to parse xml typed in that textarea. For now i build simple serversocket based server like that: import java.io.BufferedReader; import java.io.InputStreamReader; import java.io.PrintWriter; import java.net.ServerSocket; import java.net.Socket; public class WebServer { protected void start() { ServerSocket s; String gets = ""; System.out.println("Start on port 80"); try { // create the main server socket s = new ServerSocket(80); } catch (Exception e) { System.out.println("Error: " + e); return; } System.out.println("Waiting for connection"); for (;;) { try { // wait for a connection Socket remote = s.accept(); // remote is now the connected socket System.out.println("Connection, sending data."); BufferedReader in = new BufferedReader(new InputStreamReader( remote.getInputStream())); PrintWriter out = new PrintWriter(remote.getOutputStream()); String str = "."; while (!str.equals("")) { str = in.readLine(); if (str.contains("GET")){ gets = str; break; } } out.println("HTTP/1.0 200 OK"); out.println("Content-Type: text/html"); out.println(""); // Send the HTML page String method = "get"; out.print("<html><form method="+method+">"); out.print("<textarea name=we></textarea></br>"); out.print("<input type=text name=a><input type=submit></form></html>"); out.println(gets); out.flush(); remote.close(); } catch (Exception e) { System.out.println("Error: " + e); } } } public static void main(String args[]) { WebServer ws = new WebServer(); ws.start(); } } After form (textarea with xml and one additional text input) is submitted in 'gets' String-type variable I have Urlencoded values of my variables (also displayed on the screen, it looks like that: gets = GET /?we=%3Cnetwork+ip_addr%3D%2210.0.0.0%2F8%22+save_ip%3D%22true%22%3E%0D%0A%3Csubnet+interf_used%3D%22200%22+name%3D%22lan1%22+%2F%3E%0D%0A%3Csubnet+interf_used%3D%22254%22+name%3D%22lan2%22+%2F%3E%0D%0A%3C%2Fnetwork%3E&a=fooBar HTTP/1.1 What can i do to change GET to POST method (if i simply change it in form and than put " if (str.contains("POST")){" it gives me string like gets = POST / HTTP/1.1 with no variables. And after that, how i can use xml from my textarea field (called 'we')?

  • Objective-c design advice for use of different data sources, swapping between test and live

    - by user200341
    I'm in the process of designing an application that is part of a larger piece of work, depending on other people to build an API that the app can make use of to retrieve data. While I was thinking about how to setup this project and design the architecture around it, something occurred to me, and I'm sure many people have been in similar situations. Since my work is depending on other people to complete their tasks, and a test server, this slows work down at my end. So the question is: What's the best practice for creating test repositories and classes, implementing them, and not having to depend on altering several places in the code to swap between the test classes and the actual repositories / proper api calls. Contemplate the following scenario: GetDataFromApiCommand *getDataCommand = [[GetDataFromApiCommand alloc]init]; getDataCommand.delegate = self; [getDataCommand getData]; Once the data is available via the API, "GetDataFromApiCommand" could use the actual API, but until then a set of mock data could be returned upon the call of [getDataCommand getData] There might be multiple instances of this, in various places in the code, so replacing all of them wherever they are, is a slow and painful process which inevitably leads to one or two being overlooked. In strongly typed languages we could use dependency injection and just alter one place. In objective-c a factory pattern could be implemented, but is that the best route to go for this? GetDataFromApiCommand *getDataCommand = [GetDataFromApiCommandFactory buildGetDataFromApiCommand]; getDataCommand.delegate = self; [getDataCommand getData]; What is the best practices to achieve this result? Since this would be most useful, even if you have the actual API available, to run tests, or work off-line, the ApiCommands would not necessarily have to be replaced permanently, but the option to select "Do I want to use TestApiCommand or ApiCommand". It is more interesting to have the option to switch between: All commands are test and All command use the live API, rather than selecting them one by one, however that would also be useful to do for testing one or two actual API commands, mixing them with test data. EDIT The way I have chosen to go with this is to use the factory pattern. I set up the factory as follows: @implementation ApiCommandFactory + (ApiCommand *)newApiCommand { // return [[ApiCommand alloc]init]; return [[ApiCommandMock alloc]init]; } @end And anywhere I want to use the ApiCommand class: GetDataFromApiCommand *getDataCommand = [ApiCommandFactory newApiCommand]; When the actual API call is required, the comments can be removed and the mock can be commented out. Using new in the message name implies that who ever uses the factory to get an object, is responsible for releasing it (since we want to avoid autorelease on the iPhone). If additional parameters are required, the factory needs to take these into consideration i.e: [ApiCommandFactory newSecondApiCommand:@"param1"]; This will work quite well with repositories as well.

  • asp.net mvc & jquery dialog: What approach do I take to add items to a dropdownlist/select list with

    - by Mark Redman
    Hi, I am new to MVC and have a grasp of the basic model, but still doing everything with postbacks etc. One aspect of the UI I want to build is to have a drop-down-list of items with a button to add an item to the database and refresh the list. Achieving this with WebForms was straight forward as everything was wrapped in UpdatePanels, but what is the best approach to achieve this using MVC? Part of the markup for the list and button look like this: <table> <tr> <td><%=Html.DropDownList("JobTitleSelectList", Model.JobTitleSelectList, "(select job title)", new { @class = "data-entry-field" })%></td> <td>&nbsp;</td> <td><a id="AddJobTitleDialogLink" href="javascript: addJobTitleDialog();" title="Add Job Title"><img id="AddJobTitleButtonImage" src="/Content/Images/Icons/16x16/PlusGrey.png" border="0" /></a></td> </tr> </table> The Dialog is a standard jquery Ui dialog, looks like this: <div id="SingleTextEntryDialog" style="display:none"> <table> <tr> <td>Name:</td> <td><input id="SingleTextEntryDialogText" type="text" size="25" /></td> </tr> </table> </div> I am guessing I need to put this into a UserControl / PartialView (are they the same thing?) Also with the strongly typed View how do I pass the Model or just the SelectList Property to the UserControl or is this not the case? Nor sure if there should be form in the dialog div? or how that is going to postback via ajax. Some examples show a lot of ajax code in the page something like: $.ajax({...}); I assume doing this using jquery is more code than asp.net webforms, but there is just more code to see doing a "View Source" on a page? Your comments appreciated.

  • web service filling gridview awfully slow, as is paging/sorting

    - by nat
    Hi I am making a page which calls a web service to fill a gridview this is returning alot of data, and is horribly slow. i ran the svcutil.exe on the wsdl page and it generated me the class and config so i have a load of strongly typed objects coming back from each request to the many service functions. i am then using LINQ to loop around the objects grabbing the necessary information as i go, but for each row in the grid i need to loop around an object, and grab another list of objects (from the same request) and loop around each of them.. 1 to many parent object child one.. all of this then gets dropped into a custom datatable a row at a time.. hope that makes sense.... im not sure there is any way to speed up the initial load. but surely i should be able to page/sort alot faster than it is doing. as at the moment, it appears to be taking as long to page/sort as it is to load initially. i thought if when i first loaded i put the datasource of the grid in the session, that i could whip it out of the session to deal with paging/sorting and the like. basically it is doing the below protected void Page_Load(object sender, EventArgs e) { //init the datatable //grab the filter vars (if there are any) WebServiceObj WS = WSClient.Method(args); //fill the datatable (around and around we go) foreach (ParentObject po in WS.ReturnedObj) { var COs = from ChildObject c in WS.AnotherReturnedObj where c.whatever.equals(...) ...etc foreach(ChildObject c in COs){ myDataTable.Rows.Add(tlo.this, tlo.that, c.thisthing, c.thatthing, etc......); } } grdListing.DataSource = myDataTable; Session["dt"] = myDataTable; grdListing.DataBind(); } protected void Listing_PageIndexChanging(object sender, GridViewPageEventArgs e) { grdListing.PageIndex = e.NewPageIndex; grdListing.DataSource = Session["dt"] as DataTable; grdListing.DataBind(); } protected void Listing_Sorting(object sender, GridViewSortEventArgs e) { DataTable dt = Session["dt"] as DataTable; DataView dv = new DataView(dt); string sortDirection = " ASC"; if (e.SortDirection == SortDirection.Descending) sortDirection = " DESC"; dv.Sort = e.SortExpression + sortDirection; grdListing.DataSource = dv.ToTable(); grdListing.DataBind(); } am i doing this totally wrongly? or is the slowness just coming from the amount of data being bound in/return from the Web Service.. there are maybe 15 columns(ish) and a whole load of rows.. with more being added to the data the webservice is querying from all the time any suggestions / tips happily received thanks
