• Game Technologies: DirectX, XNA, XACT, etc. Custom Vertex Format

  I have been playing around with creating my own custom vertex formats in XNA. To test whether it works I am creating a vertex format that is the same as VertexPositionColor. I created a struct with a Position, Color and SizeInBytes property. Creating the vertex element array is also no problem. Until here my vertex format and that of VertexPositionColoris exactly the samen. The only thing that is different is what both return in the GetHashCode method. I believe this value is used to actually use it (in combination with the vertex element array to index this value). In the GetHashCode method I return: this.Position.GetHashCode() | this.Color.PackedValue.GetHashCode(); I got this from this article . Can anyone tell me what I am doing wrong ...Show All

• Visual Basic Picture Splitting 2D RPG DirectX

  Say if i wanted to split a picture up into an array, every 32x32 pixels is a index of the array. So like i could say i want index 1 to go here (x, y)... then index 2 (some other x, y) to go here and so on. I have no idea how to do this and no idea where to start. For an assignment in either VB 6.0 or VB.Net i have to create a basic 2D game and i decided that this would be the best way to do so (since loading an array of picture boxes uses up alot of memory). If there is a better way then please tell me. The ability to have the map move (so you can explore) Which is a scrolling map, like pokemon. Keyboard inputs to move the sprite. The rest i will figure out myself, but if you generous you will tell me them . I ...Show All

• Visual Studio Bug: MSBuild forbids resetting of properties passed as arguments to any outer instance

  I have noticed some odd behavior with MSBuild and properties that are specified on the command line or in MSBuild tasks. It is (sometimes ) not possible to change the value of such properties declaratively inside a <PropertyGroup> neither is it possible to change them using <CreateProperty>. In both cases the new value is *silently* discarded! Worse, it appears that nested MSBuild instances also inherit the same problem. So if I happened to pass a property to an MSBuild script via the command line then use the <MSBuild> task to launch a nested instance of the interpreter, not only does the property get inherited into its scope when it shouldn't (because it was not specified in the Properties attribute) but I *still* ca ...Show All

• Visual Basic Graphics.DrawString draws too thick

  I use the following code: Dim brush As New Drawing.SolidBrush(Color.FromKnownColor(KnownColor.ControlText)) Dim font As New Font( "Microsoft Sans Serif" , 11.25!, FontStyle.Regular, GraphicsUnit.Point) Dim bmp As Bitmap = New Bitmap(pic_main.Width, pic_main.Height) Dim gfx As Graphics = Graphics.FromImage(bmp) gfx.DrawString( "Choose a game from the list to continue." , font, brush, 8, 8) gfx.Save() gfx.Dispose() It draws the string very thick and it is almost unreadable. I wanted it to look as it would if it was a label control. Is there a way I can set the thickness of the brush Or even make the string appear as it would on a label control. Thanks, Troy Dim font As New Font ...Show All

• Windows Forms Window shrinking on restore.

  I'm using Visual C# 2005 Express to make a windows forms application. The application works fine but when I added some user settings to keep track of the window size and position, the window shrinks to no size when the window is restored. If I start the application, resize the window, and close it, it will remember its size and position on restart. When I minimize the window and then restore it, however, it briefly returns to it's original size (a fraction of a second) and then resizes itself to have no client area at all. I can then manually resize it to it's original size. What is going on Thanks for any help. Bob The only code I wrote is this: private void MainForm_FormClosed( object sender, FormClosedE ...Show All

• Windows Search Technologies WDS 3 - RTW Final not indexing .xlsx file which have ODBC SQL Connection

  Hello, Brandon recommended me posting this problem I noticed in the WDS 3 RTW. Basically the WDS 3 RTW, and (Beta 2) cant index the contents of Excell new format (.xlsx), if the excell contains a ODBC (SQL database) connection. The easy way to reproduce is to, create a new .xlsx file using Office 2007 B2TR, create a ODBC SQL connection to any database/table that you have access to. Save the file and wait for index, it will index the filename but never its content. With the WDS 2.6.5 this problem doenst happen. Regards, Marcus Dear Daniel, Thanks for looking into this problem, it has been very difficult not to be able to search within those files. I have emailed you the .xlsx file, Few comments: 1) ...Show All

Thanks Dan Print preview uses the printer driver to provide the preview. This driver will probably try to communicate with the actual printer, looking for stuff like currently selected printer options. Try installing the printer locally and make that local printer your default printer. ...Show All

• Software Development for Windows Vista SetStateActivity - set TargetStateName during Execution of Statemachine

  Hi all, I have a statemachine. In several states I can get into a "special" state. From the "special"state I have to go back to the state I came from. Now there is the Statemachine property PreviousStateName available. I wanted to set the Dependencyproperty "TargetStatename" of the SetStateActivity to that PreviousStateName by a codeactivity. But setting the targetstatename of the setStateActivity is only allowed during DesignTime... Now I tried to reflector the SetStateActivity(in order to create my own SetState) but its quite a deal of effort since its got a helper procedure tail in several workflow helperclasses which are internal. Are there already any activities around which fullfill the requirements abov ...Show All
