• Windows Forms Unsubscribing from all events

  Hi, I have a control and throughout my code I have multiple places where I subscribe to events e.g. MyEvents.SetNumberEvent += new MyEvents.SetNumberHandler(SetNumber); I'm having a problem that when some controls are disposed these subscriptions to events are not disposed with the control so when an event fires exceptions to do with the disposed control are thrown. Is there a way for me (in my HandleDestroyed method) to go through all the events I've subscribed to and unsubscribe from them rather than finding every event in my code and unsubscribing one-by-one myself Thanks in advance. Friendly Dog and RizwanSharp, I think you both missed my point - I know how to unsubscribe from an event but I wanted t ...Show All

• Windows Forms TextbBox size in GridView Edit mode

  I have a GridView with a field that contains long strings of text. I would like to make the grid directly editable, rather than using a details view. I finally figured out how to make the TextBox in the Edit view bigger, but I cannot find option to to make the text in it wrap or for adding scroll bars. Is there a way to accomplish what I'm trying to do, either with control properties or through manual coding Thanks in advance for your advice. Steve There is a property for the textbox called "Textmode". change the property to Multiline, it will add a verticle scrollbar and wrap text in the horizontal.

• SQL Server T-SQL Badly needed

  To one of our sql server database Table A , we need to migrate data from another sql server database Table B . Assume there are two columns in a table namely OrderID and Comments .

• Visual Studio Error: When using FriendlyFilenames explicit interface methods are not compiled in CHM file

  Hi, When using friendlyfilenames no explicit interface methods are included in the chm-file builder process. This is because the filename of such a method is named like: M_MyWebControl_System#Web#UI#IPostBackEventHandler#RaisePostBackEvent_1_72eac341.htm I believe the CHM-builder process doesn't like the #-character in the filename referenced, so it thinks that the file isn't referenced and this causes the file not be compiled in the CHM-file. When using GUIDFilenames everything works just fine. Kind regards, Stephan Smetsers Thanks Stephan for finding this issue. As Pritam mentions we will fix this for our December drop.

• Game Technologies: DirectX, XNA, XACT, etc. the error

  I would like my game to come up to the opening scene, and when i press the spacebar it goes away and my game starts. I have tried something like this in my program: void _startGame; { using (Blank game = new Blank()) { game.Run(); } } But when i press spacebar it gives me an error. Thanks, for the help! You might want to look into using GameComponents or a similar OO method of handling what's displayed. For a small game you can get away with doing things like that, but the more you add to it the more difficult it's going to be to maintain. I believe there's some tutorials on doing this on the various XNA tutorial sites. ...Show All
