• Game Technologies: DirectX, XNA, XACT, etc. Working with buffers in 2D

  Hello all, I've been trying to figure out how the system with backbuffers work. In all examples I have found people are clearing the buffer before they draw something new. graphics.GraphicsDevice.Clear(Color.Black); ...draw some sprites... graphics.GraphicsDevice.Present(); I guess that when you enter the Draw method you are working with the backbuffer, so the clear() and the sprite draw() will affect the backbuffer. After that you call the Present() to draw the recently made backbuffer on the screen. My problem is that this is not how I would like to do it in my case. Everytime I enter the Draw() method I would only like to add some new things, and not clear anything. The easiest way to do this is to not have any backbuffer at all, but I ...Show All

• Visual Studio Team System Usernames in TFS

  Hi! I have a question about the usernames (fullnames) in TFS. As TFS displays now, it displays the fullname of the user loginname in userrelated fields (like Assigned To). So if you have a user DOMAIN\User1 (With the full name FirstName LastName), it will display FirstName LastName in these fields. The problem is that if DOMAIN\User1 changes name to FirstName emaNtsaL on the domain, the userrelated fields still displays FirstName LastName! After some digging I found out that the fullname for the user account is stored in the table Constant, but it's not updated whenever the domain is.. Why's this The reason why I discovered this problem was that I am developing a lightweight webpart that should handle some WorkItemTracking, and ...Show All

• Windows Forms Visual Basic Defaults

  I do not like some of the defaults that Microsoft has implemented in the 2005 Pro edition. I would like to change them but am at a loss as to how to go about this. Help or direction will relieve my current frustrations. An example of what I would like to change is: the label default properties for 'Autosize' is set to true, I want this default to be false. I have many others to numerious for here but if I can get the answer to this one I'm sure I can work the others out. Hi, These values or Control Properties are defaults which in my opinion are reasonable. If you want, you can subclass all the .NET controls and alter their default values. That way you can just use your own controls on all your forms, a ...Show All

• Audio and Video Development Tee node and custom media source

  I used the WavSource MediaSource example and I used it in topology using a tee node. When I do that, an errors occurs after starting the session (0x8000FFFF).

I just finished installing RC2 (5744) and it works now. Thanks for looking into it. Marc ...Show All

• Windows Forms Problem With NumericUpDown

  when i set the min value for 10 for example like this NumericUpDownMax.Minimum= 10 and then set again the Minimum to 5 for example like this NumericUpDownMax.Minimum= 5 the problemi is that the minimum doesn't change and stay at number 10 do you if I missed something Thank you in advance Dror. The only explanation for this is that you are using the wrong form reference. You might have created a new instance of the form that contains NumericUpDownMax that is not visible. Easy to do, especially in VB.NET. Call Show() after your statement to verify. ...Show All
