• Windows Forms How to clear old data from DataGridView and DataSet?

  As an exercise in learning Visual Basic 2005, I am putting together a simple XML editor. I place on the form the objects DataGridView1 and DataSet1. ' Read an XML file into DataSet1: DataSet1.ReadXml("BIRDS.XML") ' Bind the DataGridView to the DataSet: DataGridView1.DataSource = DataSet1 ' Having determined that the TableName of the ' DataTable I am interested in is "bird", ' make this the DataMember of the DataGridView: DataGridView1.DataMember = "bird" ' Set up autogeneration of columns: DataGridView1.AutoGenerateColumns = True And now the contents of the file appear in the grid for viewing and editing.

• Visual Basic How to read the value of a DataGrid cell

• Visual Studio Winform ReportViewer Background Thread

  Hi All I'm currently trying to make our winform application more responsive, and I'm having a few problems with the reportviewer. I'm trying to call RefreshReport on a backgound thread. However, because this method call is intrinsically bound to a control that is on the UI thread, this is not allowed. There in lies my problem. Is there any way to refresh the report asynchronously I'm confused as there is a method called " CancelRendering " that stops background processing of the report. But how on earth do you start it. Any advice would be gratefully received. Hopefully I'm just missing somthing obvious. Regards Darren Brian, Thanks for the informative answer. I can definately move on from my curr ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Rendering 2D and 3D meshes at the same time

  I followed the help menu's to render a background and then I followed the help menu's to load and render a 3D mesh. Rendering a background works great, rendering a 3D mesh works great. Both of these are files from Spacewar. However, rendering both TOGETHER fails. I'm doing the following: protected override void Draw(GameTime gameTime) { graphics.GraphicsDevice.Clear(Color.CornflowerBlue); spriteBatch.Begin(); spriteBatch.Draw(background, backgroundPos, null, Color.White, 0, Vector2.Zero, 1, SpriteEffects.None, 1.0f); spriteBatch.End(); //Draw the model, a model can have multiple meshes, so loop foreach (ModelMesh mesh in shipModel.Meshes) { //T ...Show All

• Silverlight (formerly WPF/E) Anybody successfully using Glyph UnicodeString?

  After I posted http://www.wynapse.com/WPFE/WPFE_Glyph_Explorer.aspx , Mike Harsh hinted that I could also use UnicodeString. I tried to display the UnicodeString value below the Indice in that code and all I got was "undefined" or something like that. I figured if I simply displayed the UnicodeString for an already displayed Glyph, it would let me know what I need to input to get what I want. Is this working, or is this another Glyph thing that isn't Thanks... -Dave UnicodeString doesn't return you the unicode version of glyphs displayed with the GlyphIndicies property -- the UnicodeString only returns you what you set it.

• SQL Server XML to CSV

• Visual Studio 2008 (Pre-release) .NET 3.0 / Orcas / C# 3.0 / LINQ - I'm Confused

  Hi, I'm wondering if someone could clarify for me the relationship between .NET 3.0 (which is currently RC1) and all of this LINQ stuff we're seeing in the May CTP. I apologize if this is addressed elsewhere but I haven't been able to find it. As I understand it, .NET 3.0 is supposed to be released with Vista. C# 3.0 and LINQ will be released together as the next version of Visual Studio (AKA Orcas ), but separately from .NET 3.0 and probably well after Vista. This situation confuses me a little bit because the .NET Framework has a C# compiler built into it, right So I'm guessing that the C# compiler included in the .NET Framework 3.0 will not be able to compile C# 3.0 code (LINQ, etc.) Does that mean there will be another framew ...Show All

• Software Development for Windows Vista CriticalSection Changed.

  I was reading the article at http://msdn.microsoft.com/windowsvista/default.aspx pull=/library/en-us/dnlong/html/AppComp.asp and noticed the section about critical sections. There is a bullet point that says the following. "Should prevent starvation. Applications that call Sleep while holding the critical section lock now can cause starvation for other threads that need the lock. Sleep calls should be placed after the LeaveCriticalSection call. " I would really like some more information on this. Is that saying that if i sleep while i own a critical section that another thread trying to obtain the critical section may have problems (other than it blocking until the owning thread releases the critical section) If so why and ...Show All

• SQL Server Asynchronous events to database clients via DAL?

  Greetings, I have a requirement for a SQL Server 2005 database to notify 3rd Party applications of a table change. As is stands now, 3rd Party applications access the database via a Data Access Layer (DAL) dll (C#). I'd like to somehow implement an asychronous event notification scheme via the same DAL to these clients. Can someone offer a clever way to implement such events Broker Services I am under the impression the SSBS is typically deployed when databases are to communicate with one another.

• Visual Studio Express Editions Group delimiters are not balanced

  I was looking for a quick and dirty way of making an OpenFileDialog show thumbnails. Using the keyboard Five tabs, four Downs and an Enter seemed to do the trick so I thought I would use SendKeys (from a timer to overcome the fact that the dialog is modal) - I said it was dirty but it's only for my own use. The tabs work fine but sending a down key results in the error message of the title. At which point I gave up - anyone any ideas.
