Oops... It's not completely true! On some machines it make the application crash! I installed the last video card drivers, but ... it crashes! Does anybody know why ? :o

I developer a program in C# that uses OpenGL. In some cases (for example when someone connect to my computer using Remote Assistance) I have DDERR_SURFACELOST error. I suppose that I must restore DirectDraw Surface but ... how can I do it ?? :eek: Can anyone help me ? Thanks

I think to have found the solution (... now it works). In my UserControl I just added public class WSEX { ..... public const int _COMPOSITED = 0x02000000; }; protected override CreateParams CreateParams { get { CreateParams createParams = base.CreateParams; createParams.ExStyle |= WSEX._COMPOSITED; return createParams; } } :) Thanks to those who helped me.

:mad: Hi! I developed a C# User Control that uses OpenGL graphic libraries. It simply shows some objects moving in a 3d space ... I tried to use Windows XP Remote Assistance and while I clearly see everything (Desktop,Taskbars, ...) I only see a black rectangle where I should see my application running. Does anybody know what I did wrong ?? Should I distribute some DLL files with my applications ?? Thanks in advance Max
