in a function named buildtexture, it loaded the image and build texture for OpenGL, when i called CreateDIBSection, it will creat a bitmap. If the function buildtexture was called as a normal member function, there will be nothing wrong. But if i called this member function in a thread, the CreateDIBSection will return 0 that means it f...

Hi, I am trying to create Cursor from png, and CreateDIBSection() is throwing. Follwoing is the snippet of code: HDC hdc = GetDC(NULL); void* lpBits = NULL; HBITMAP hBitmap; try { hBitmap = CreateDIBSection( hdc, (BITMAPINFO*)&bi, 0, &lpBits, NULL, (DWORD)0); } ReleaseDC(NULL, hdc); As CreateDIBSection is throwing, th...
Whenever my app tries to create a DIB section, either by calling CreateDIBSection(), or by calling LoadImage() with the LR_CREATEDIBSECTION flag, it seems to return successfully. The HBITMAP it returns is valid, and I can manipulate and display it just fine. However, calls to GetLastError() will return 8: Not enough storage is availabl...
Hello there! I have an application with transparent background in client area which is drawn black because the window is not layered. In each of it's WM_PAINT messages I am doing a BitBlt to a memory-DC, after that I use the memory-DC with UpdateLayeredWindow to a layered canvas window. setup of memory-DC: HDC hdcMemory = CreateCompat...
