Could you tell us more about what you are trying to do? Based on what you've said, I think you'll want to probably not peek the whole thing, but just what you need when you need it, and poke values back as required. But that's just my speculation based on what you've said.

Matt

SAFEARRAY* DisplayBuffer = NULL;
 
int __stdcall takeScreen() { 
  if (DisplayBuffer) { 
    SafeArrayDestroy(DisplayBuffer); 
    DisplayBuffer=NULL; 
  } 
  HRESULT rc = VirtualDisplay->TakeScreenShotToArray(0, DisplayWidth, DisplayHeight, &DisplayBuffer); 
  return SUCCEEDED(rc) ? EU_TRUE : EU_FALSE; 
}

I want to get screenshot and export it, pixel-by-pixel, to my program, written in Euphoria. May be, "takeScreen" must return pointer to DisplayBuffer?

P.S. Why TABs not converted to two spaces inside eucode tag? It is inconvenience.
