• .NET Development Search for most matching data in Dataview

  Hi I've loaded my Excel file into a dataset and created a dataview. Now I want to filter the dataview according to the user input. What I want to know is that can I search for the most matcing item For example, there is a column in my dataview called "Length" which includes 4, 6, 8, 9, 10, 11, 12, 13.

I have a button that onclick, will have a function to check the current month (Local time), eg. if current month equal Nov, open form X else if current month equal Dec, open form Y. Tks. The property Month is already of type int, so just do this: cur_mth = DateTime.Now.Month; switch(cur_mth) { case 10: // do your October stuff break; case 11: // do your November stuff break; } Month will contain values from 1 to 12 with 1 for Januar and 12 for December.

• Visual Studio Express Editions Type comparison: GetType, TypeOf, Equals.... which one is most efficient?

  Hi folks; suppose I want to figure out what type a certain control is. Then, what is the most efficient way to do it - use If (ctrl.GetType Is GetType(ComboBox) )Then ..... - or If (ctrl.GetType = GetType(ComboBox) )Then ..... - or If (ctrl.GetType.Equals(GetType(ComboBox)) Then ... - or If (TypeOf ctrl Is ComboBox) Then ....

• Visual Studio 2008 (Pre-release) How can I clone BitmapImage

  When I do: bitmap.CloneCurrentValue(); bitmap.Clone(); and set it as Image.Source I get an error that the decoder could not decoe the image. When I remove the cloning it works great, but now the file is locked and wanting to delete it throwing exception. any Ideas. btw This exact same code worked great in windows forms. Hi, Itzik. The Clone() operation won't actually help you here, because instead of releasing the reference to the file it will create another reference to it.To get around the file locking behavior, construct the bitmap with the BitmapCacheOption.OnLoad argument set: BitmapImage bi = new BitmapImage(); // BitmapImage.UriSource must be in a BeginInit/EndInit block. ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Loading 3D Landscapes

  Hello, I would like to start this thread as hopefully a complete how-to with 3D Landscapes until the documentation is availalble. Here are my initial questions: These would pertain more for those that want a shooter or mmorg, but useful for all! 1.) How would one load a 3d heightmap and view it 2.) How can you apply splatting to the landscape using alpha maps 3.) How can one go about paging the landscape ie: each sector would be (say 512 x 512) - how can you load/unload the maps to save resources. 4.) Performance - why choose .png over .bmp or .jpg for heightmap, alphamp and textures Thank you everyone for your responses. I guess i need to decide how to proceed - i have invested a ...Show All

• Visual Studio Team System Permanently Delete Work Items?

  Hi, I'm running TFS Beta 2 and VS 2005 Beta 2. I was wondering if there is any way to permanently delete work items Not just to mark them as Closed, but completely get rid of them I have full access to the server. Is there a safe way to go into SQL Server and delete items from the database, or are there command lines tools to perform this Thanks, Kevin We had the same problem and where able to delete them via this SQL statement. Make sure you set the DELID (1729) to the Work Item ID that you want to delete. Tread Lightly.... I am no expert but it seams to work for us. Declare @DELID int set @DELID = 1729 DELETE FROM [TfsWorkItemTracking].[dbo].[WorkItemLongTexts] WHERE ID = ...Show All
