  • Convert C# (with typed events) to VB.NET

    - by Steven
    I have an ASPX page (with VB Codebehind). I would like to extend the GridView class to show the header / footer when no rows are returned. I found a C# example online (link) (source). However, I cannot convert it to VB because it uses typed events (which are not legal in VB). I have tried several free C# to VB.NET converters online, but none have worked. Please convert the example to VB.NET or provide an alternate method of extending the GridView class. Notes / Difficulties: If you get an error with DataView objects, specify the type as System.Data.DataView and the type comparison could be the following: If data.[GetType]() Is GetType(System.Data.DataView) Then Since the event MustAddARow cannot have a type in VB (and RaiseEvent event doesn't have a return value), how can I compare it to Nothing in the function OnMustAddARow()? EDIT: The following is a sample with (hopefully) relevant code to help answer the question. namespace AlwaysShowHeaderFooter { public delegate IEnumerable MustAddARowHandler(IEnumerable data); public class GridViewAlwaysShow : GridView { ////////////////////////////////////// // Various member functions omitted // ////////////////////////////////////// protected IEnumerable OnMustAddARow(IEnumerable data) { if (MustAddARow == null) { throw new NullReferenceException("The datasource has no rows. You must handle the \"MustAddARow\" Event."); } return MustAddARow(data); } public event MustAddARowHandler MustAddARow; } }

  • How to "pin" C++/CLI pointers

    - by Kumar
    I am wrapping up a class which reading a custom binary data file and makes the data available to a .net/c# class However a couple of lines down the code, i start getting the memory access violation error which i believe is due to the GC moving memory around, the class is managed Here's the code if ( ! reader.OpenFile(...) ) return ; foreach(string fieldName in fields) { int colIndex = reader.GetColIndex( fieldName ); int colType = reader.GetColType( colIndex ); // error is raised here on 2nd iteration } for ( int r = 0 ; r < reader.NumFields(); r++ ) { foreach(string fieldName in fields) { int colIndex = reader.GetColIndex( fieldName ); int colType = reader.GetColType( colIndex ); // error is raised here on 2nd iteration switch ( colType ) { case 0 : // INT processField( r, fieldName, reader.GetInt(r,colIndex) ); break ; .... } } } .... i've looked at interior_ptr, pin_ptr but they give an error c3160 cannot be in a managed class Any workaround ? BTW, this is my 1st C++ program in a very long time !

  • Will "Programming in the Cloud" Ever Take off?

    - by Pierreten
    Just got a chance to try out a cloud programming environment that let's you develop .net apps within the browser (http://coderun.com/ide/) I found it pretty interesting, since I was able to develop a mockup ASP.net site on an IPad. With javascript engines in browsers becoming faster and faster, cheap server infrastructure to compile on; will the cloud become the IDE platform of the future?

  • Auto comment all public members in a file

    - by ooo
    I have turned on warnings as errors and now i need to XML comment all of my public methods. just to get my program compiling, i just want to put placeholders for now. Is there anyway to automatically add XML comments to all of the public members in a class or a file. I see ghost doc which gives you good autogenerated XML comments but it still looks like it only does one member at a time.

  • Using VS Code Snippets with Resharper

    - by devoured elysium
    I am trying to use Code Contract's Code Snippets but since I turned Resharper back on it doesn't recognize them. On the other hand, it is recognizing some snippets I've implemented myself in the past. Any ideia of what might be the problem? I'm specifically trying to use cr and ce, which I think, don't collide with any other snippets (at least from what I see in the intellisense). I'm using R# 5 with VS 2010 Thanks

  • Running an application from an USB device...

    - by Workshop Alex
    I'm working on a proof-of-concept application, containing a WCF service with console host and client, both on a single USB device. On the same device I will also have the client application which will connect to this service. The service uses the entity framework to connect to the database, which in this POC will just return a list of names. If it works, it will be used for a larger project. Creating the client and service was easy and this works well from USB. But getting the service to connect to the database isn't. I've found this site, suggesting that I should modify machine.config but that stops the XCopy deployment. This project cannot change any setting of the PC, so this suggestion is bad. I cannot create a deployment setup either. The whole thing just needs to run from USB disk. So, how do I get it to run? (The service just selects a list of names from the database, which it returns to the client. If this POC works, it will do far more complex things!)

  • Changing colour of types for VB.net in VS

    - by vdh_ant
    I am currently working on a VB.NET project and the hardest thing that I am having trouble with is that everything is black and blue. Having worked a lot with C#, I really like the way that types are colored differently. I have tried going in and having a look at the "Tools > Options > Fonts and Colors" and the various "User Types" under "Display Items" is set to a different colour but its not reflecting that colour in the text editor. Any assistance would be appreciated.

  • VisualSVN and VS2008 integration - moving files

    - by tyndall
    If I drag and drop tracked .cs files to new folders in VS2008 with VisualSVN what message should I see when I commit the .cs file? I see added (+) shouldn't I see a "move"? I'm asking because I'm getting ready to do a major refactoring (including moving lots of files) and I don't want to lose my version history on these files. Note: I'm very new to Subversion, TortoiseSVN, and VisualSVN.

  • Positioning the dialog box in the centre of the screen

    - by ame
    I have a dialog box developed in mfc for a Windows CE device and want it to occupy the entire screen. I used the following code to center my dialog box on the lcd screen of the device: CWnd* pWnd = GetDesktopWindow(); CenterWindow(pWnd); However, I still get a tiny sliver of space on the left side of the dialog box, resizing the dialog merely makes it overflow on the right side of the LCD while the tiny space on the left remains (I can see the blue of the win CE desktop behind.) Are there any suggestions to solve this problem? I checked the margin settings for this dialog box in my .rc files and leftmargin and topmargin are both set to 0. I was wondering if I could get the coordinates of the centre of the screen and then place my window one or two points to the left to deal with the current offset. A messy approach I know!

  • Change a registry value in vb.net

    - by mhofer
    Hello, I have searched a lot to find a solution for my problem, but I can't find any specific solution. I need to change a value which is stored under HKEY_LOCAL_MACHINE\SOFTWARE\APP_NAME. It is not possible to use .NET's registry functions, since they have drastic restrictions. The following snippet should solve my problem: Dim regKey As RegistryKey Dim ver As Decimal regKey = My.Computer.Registry.LocalMachine.OpenSubKey("HKEY_LOCAL_MACHINE\SOFTWARE\APP_NAME", True) regKey.SetValue("IP", "192.168.10.15:18500") regKey.Close() Unfortunately, I get a NullReferenceExeption when I try to set the value. What should I do? I have imported Microsoft.Win32 and RegistryKey doesn't accept any constructor... cheers mike

  • Why is std::tr1::shared_ptr<>.reset() so expensive?

    - by Paul Oyster
    Profiling some code that heavily uses shared_ptrs, I discovered that reset() was surprisingly expensive. For example: struct Test { int i; Test() { this->i = 0; } Test(int i) { this->i = i; } } ; ... auto t = make_shared<Test>(1); ... t.reset(somePointerToATestObject); Tracing the reset() in the last line (under VC++ 2010), I discovered that it creates a new reference-counting object. Is there a cheaper way, that reuses the existing ref-count and does not bother the heap?

  • redirect web app results to own application

    - by vbNewbie
    Is it possible to redirect a web apps results to a second application? I cannot parse the html source. It contains the javascript functions that execute the queries but all the content is probably server side. I hope this makes sense. The owner has made the script available but I am not sure how this helps. Can I using .net call the site and redirect results perhaps to a file or database? the app accesses one of googles apis and performs searches/queries and returns results which are displayed on the site. Now all the javascript functions that perform these queries are listed in the source but I do not know javascript so it does not make much sense to me. I have used the documentation which uses the oauth protocol to access the api and have implemented that in my web app but it took me nearly a week to get the request token right and now to send requests to the api, sometimes I get one result back and sometimes none. It is frustrating me and the owner of the web app has given use of his script but he says all that happens is that my browser interacts with the google api and not his server. So I thought why not have my web app call his, since his interacts with the API flawlessly and have the results sent to my app to save in a database. I have very little experience here so pardon my ignorance

  • Works on debug but not release

    - by user146780
    I have a thread that sets a value to true when it is done. Until then I wait: while(1) { if(done[0] == true) { break; } } This code works just fine in Debug but in Release it stays in the loop forever even though the debugger clearly says that it is true and not false. Why would this not work? Thanks

  • Explain to me the following VS 2010 Extension Sample code..

    - by ealshabaan
    Coders, I am building a VS 2010 extension and I am experimenting around some of the samples that came with the VS 2010 SDK. One of the sample projects is called TextAdornment. In that project there is a weirdo class that looks like the following: [Export(typeof(IWpfTextViewCreationListener))] [ContentType("text")] [TextViewRole(PredefinedTextViewRoles.Document)] internal sealed class TextAdornment1Factory : IWpfTextViewCreationListener While I was experimenting with this project, I tried to debug the project to see the flow of the program and I noticed that this class gets hit when I first start the debugging. Now my question is the following: what makes this class being the first class to get called when VS starts? In other words, why this class gets active and it runs as of some code instantiate an object of this class type? Here is the only two files in the sample project: TextAdornment1Factory.cs using System.ComponentModel.Composition; using Microsoft.VisualStudio.Text.Editor; using Microsoft.VisualStudio.Utilities; namespace TextAdornment1 { #region Adornment Factory /// /// Establishes an to place the adornment on and exports the /// that instantiates the adornment on the event of a 's creation /// [Export(typeof(IWpfTextViewCreationListener))] [ContentType("text")] [TextViewRole(PredefinedTextViewRoles.Document)] internal sealed class TextAdornment1Factory : IWpfTextViewCreationListener { /// /// Defines the adornment layer for the adornment. This layer is ordered /// after the selection layer in the Z-order /// [Export(typeof(AdornmentLayerDefinition))] [Name("TextAdornment1")] [Order(After = PredefinedAdornmentLayers.Selection, Before = PredefinedAdornmentLayers.Text)] [TextViewRole(PredefinedTextViewRoles.Document)] public AdornmentLayerDefinition editorAdornmentLayer = null; /// <summary> /// Instantiates a TextAdornment1 manager when a textView is created. /// </summary> /// <param name="textView">The <see cref="IWpfTextView"/> upon which the adornment should be placed</param> public void TextViewCreated(IWpfTextView textView) { new TextAdornment1(textView); } } #endregion //Adornment Factory } TextAdornment1.cs using System.Windows; using System.Windows.Controls; using System.Windows.Media; using Microsoft.VisualStudio.Text; using Microsoft.VisualStudio.Text.Editor; using Microsoft.VisualStudio.Text.Formatting; namespace TextAdornment1 { /// ///TextAdornment1 places red boxes behind all the "A"s in the editor window /// public class TextAdornment1 { IAdornmentLayer _layer; IWpfTextView _view; Brush _brush; Pen _pen; ITextView textView; public TextAdornment1(IWpfTextView view) { _view = view; _layer = view.GetAdornmentLayer("TextAdornment1"); textView = view; //Listen to any event that changes the layout (text changes, scrolling, etc) _view.LayoutChanged += OnLayoutChanged; _view.Closed += new System.EventHandler(_view_Closed); //selectedText(); //Create the pen and brush to color the box behind the a's Brush brush = new SolidColorBrush(Color.FromArgb(0x20, 0x00, 0x00, 0xff)); brush.Freeze(); Brush penBrush = new SolidColorBrush(Colors.Red); penBrush.Freeze(); Pen pen = new Pen(penBrush, 0.5); pen.Freeze(); _brush = brush; _pen = pen; } void _view_Closed(object sender, System.EventArgs e) { MessageBox.Show(textView.Selection.IsEmpty.ToString()); } /// <summary> /// On layout change add the adornment to any reformatted lines /// </summary> private void OnLayoutChanged(object sender, TextViewLayoutChangedEventArgs e) { foreach (ITextViewLine line in e.NewOrReformattedLines) { this.CreateVisuals(line); } } private void selectedText() { } /// <summary> /// Within the given line add the scarlet box behind the a /// </summary> private void CreateVisuals(ITextViewLine line) { //grab a reference to the lines in the current TextView IWpfTextViewLineCollection textViewLines = _view.TextViewLines; int start = line.Start; int end = line.End; //Loop through each character, and place a box around any a for (int i = start; (i < end); ++i) { if (_view.TextSnapshot[i] == 'a') { SnapshotSpan span = new SnapshotSpan(_view.TextSnapshot, Span.FromBounds(i, i + 1)); Geometry g = textViewLines.GetMarkerGeometry(span); if (g != null) { GeometryDrawing drawing = new GeometryDrawing(_brush, _pen, g); drawing.Freeze(); DrawingImage drawingImage = new DrawingImage(drawing); drawingImage.Freeze(); Image image = new Image(); image.Source = drawingImage; //Align the image with the top of the bounds of the text geometry Canvas.SetLeft(image, g.Bounds.Left); Canvas.SetTop(image, g.Bounds.Top); _layer.AddAdornment(AdornmentPositioningBehavior.TextRelative, span, null, image, null); } } } } } }

  • New to VS.net (VB.net) 2008. Windows 7 aero glass stuff.

    - by StealthRT
    Hey all, i have been using VB.net 2008 for a few months and i have a question. I compiled my program and ran it in a VM running windows 7. However, the progress bar looks like it does in XP. It doesn't have that cool look to it like I've seen in many other programs running in windows 7. I have downloaded the 3.5 .net framework with sp1 and also the sdk for windows 7 (1.4+ gb dvd) but i still see nothing. Is there a check-box i am missing in VS 2008 to enable these types of features? Maybe some type of code i need to place in the program? Thanks! David

  • How to save a complete webpage using the built-in webbrowser in c#

    - by Mike
    Overall I am trying to write out a webpage to PDF. There is a web service that I can use to convert a file to pdf. So what I am trying to do is save out a webpage from the WebBrowser winforms control. I have already tried writing it out the document stream but that just gives me the html of the page and not the images that are used with it. Another way that I looked into, but have not been successful with, is trying to create an image of the WebBrowser document. I found some examples on the web that utilize the DrawToBitmap function but none of them have worked for me. Any assistance would be grateful.
