• Game Technologies: DirectX, XNA, XACT, etc. Mesh.Simplify acting weirdly?

  Hi everybody, I'm trying to do a terrain renderer lately. My terrain is made of patches, which I want to generate with a mathematical formula (fractal brownian motion). I try then to simplify  the mesh programmatically, using the function Mesh.Simplify. When i do this for one patch, everything works perfectly (Mesh is simplified). However, when I try to create more than one patch, the Mesh.Simplify drops a StackOverflowException (in mscorlib.dll). I'm using the April 2006 DirectX SDK, tested with the latest D3DX Util file and the first (2902 and 2911 build version). Here is the call stack, as shown in the IDE: [External Code] > Framework.dll!Framework.Patch.Patch(float Size = 16.0, Framework.NoiseAlgorithm Algorithm = {Framework ...Show All

• Software Development for Windows Vista Enabling Theme Support via Manifest

  My application (using the WIN32 API) enables XP Visual Styles under XP with a manifest. But when the app is run under Vista, Visual Styles / Theme Support does not get enabled.

• Windows Forms Setting the currentcell to the cell with an error

  Hello, I have just recently started using Visual Basic 2005 and I am currently having problems with my program. The program I am working on retrieves a table from the combobox (there are 4 tables) and displays the data in a datagridview. The table is then bound to textboxes, which will allow the user to enter or adjust data. My problem is when the user enters a null value in a cell I want the program to catch the null cell and alert the user, then focus back to the cell for editing. The SQL database doesnt allow null values in the columns, but I have had trouble trying to catch the null values. It doesnt throw an error if the cells are left empty or " ", so here it what I did; Private Sub DataGridView1_CellLeave(ByVal sender As ...Show All

• Visual Studio Express Editions VB PowerPack BlendPanel question

  Hi ... I am using a BlendPanel control from the free vbPowerPack library on a form in my application. When I compile the application, it runs as expected. If I copy the exe file to another PC & run the app, I get the " MyApp has encountered a problem and needs to close. We are sorry for the inconvenience " error message. So I tried copying the exe to another folder on my local PC & I get the same error when I run it. It runs just fine if I run it from the ...bin\release\ folder, but not anywhere else. I suspect that it has to do with the BlendPanel component, as that is not native to VB2005. So what do I have to do to make this app runnable on any PC Do I have to embed the DLL file in my project somehow If so, how do I ...Show All

• Visual Studio Express Editions stupid questoin about bitmaps

  I have just begun to use Visual basic recently, and I want to create a picture. I don't want to use picture boxes(they start to lag after alot of them have been placed on the form) I know that you can use bitmaps, but all the different methods I have tried to use have ended with a blue squigly line under part of the code. I would like the code to load one of theese bitmaps, via... Public(or private, whichever works)sub form1_load <insert whatever code is needed> End sub if possible. Thank you very much in advance! You don't need a PictureBox control to display a picture on form, you can paint it directly for an absolute minimum of overhead. Here's some simple code to get sta ...Show All

• SQL Server Got BIDS working, was there another way?

  i re-installed the SQLEXPR_TOOLKIT.EXE several times(4) trying to get the BIDS part to work. Each time i had the issue of it looking for the devenev.exe as others have mentioned. I gave up on a 5th install and went for the unsupported option of running vs_setup , after the toolkit.exe dumped all the install files to its temporary directory i went in there and ran it sperately... but essentially i did it the same way as this method... http://forums.microsoft.com/MSDN/ShowPost.aspx PostID=368549&SiteID=1 while this did work, it seems to be the unsupported way. http://forums.microsoft.com/MSDN/ShowPost.aspx PostID=665067&SiteID=1 Im not opposed to going back and doing it right, but was there ever a conclusion as to why the BIDS prog ...Show All

• Software Development for Windows Vista Displaying and setting activitybind from code in XOML workflow

  Dear all, I'm working on a simple re-hosted designer that can display and edit xoml workflows. At this point i'd like to show on my property editor panel the delay2 TimeoutDuration property's acitivitybind, from my xoml it's "delay1,Path=TimeoutDuratin" . I don't want to use propertygrid or propertygrid descendant, it will be a simple label or something else. Next step is how to set activitybind from code, like setting an activitybind for delay1's TimeoutDuration property. I don't want to use VS activitybind dialog this time. <SequentialWorkflowActivity x:Name="Workflow1" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/workflow"> < ...Show All
