GetSafeHdc( ).

Seriously tho, directly accessing it from where, and for what?

-fel

Are you looking for API funcion

HDC GetDC( HWND hWnd );

Earlier today i used it like this to draw on the windows calc app

//first get a window handle (your prog or other window).
//Param 1 is a class name (if more than one "Calculator"?)
HWND hwnd = FindWindowA(NULL,"Calculator");

//now get a handle to that window''s dc
HDC hdc = GetDC(hwnd);

//Draw shapes, print text -- whatever.
TextOut(hdc,50,50,"BLAH",4);
Ellipse(hdc,10,10,500,500);

Not sure if this is what you mean...

You could use directx.

HRESULT GetSurfaceFromDC(hdc,lpDDS);

and then use

HRESULT Lock(
LPRECT lpDestRect,
LPDDSURFACEDESC2 lpDDSurfaceDesc,
DWORD dwFlags,
HANDLE hEvent
);
to directly access surface.
