Screencopy in .NET - Just to bother you

[Edwin Knoppert]

Haha, i know .NET is not what you prefer but i found a snippet looking so similar to your desktopscreen copy ( http://www.jose.it-berater.org/smfforum/index.php?topic=2775.msg8263#msg8263 )

It's in dutch but doesn't matter..

And what about this procedural encapsulation:

hBitmap = GetDesktopScreen() 

...

And where is this procedure?

Encapsulations based on the low level flat API  

GDI32

Code Select Expand

'// This function return a GDI bitmap.
FUNCTION GetDesktopScreenBitmap() AS LONG

   LOCAL hDC, hMemDC, hBitmap AS LONG

'   // Get the handle of the desktop device context.
   hDC = GetDC(GetDesktopWindow())
'   // Create a compatible device context in memory
   hMemDC = CreateCompatibleDC(hDC)
'   // Create a compatible bitmap using the desktop device context.
   hBitmap = CreateCompatibleBitmap(hDC, GetSystemMetrics(%SM_CXSCREEN), GetSystemMetrics(%SM_CYSCREEN))
   IF hBitmap THEN
'      // Select the compatible bitmap into the memeory device context.
      SelectObject(hMemDC, hBitmap)
'      // Copy bitmap to the memory device context.
      BitBlt(hMemDC, 0, 0, nSize.cx, nSize.cy, hDC, 0, 0, %SRCCOPY)
'      // Delete memory device context.
      DeleteDC(hMemDC)
'      // Release desktop device context.
      ReleaseDC(GetDesktopWindow(), hDC)
   END IF
   FUNCTION = hBitmap

END FUNCTION

GDIPLUS

Code Select Expand

'// This function return a GDIPLUS image.
FUNCTION GetDesktopScreenImage() AS LONG
   LOCAL hBitmap, hImage AS LONG
   hBitmap = GetDesktopScreenBitmap()
   IF hBitmap THEN
'      // Note: GDI+ must have been initialized elsewhere.
      IF GdipCreateBitmapFromHBITMAP(hBitmap, BYVAL 0, hImage) = 0 THEN
         FUNCTION = hImage
      END IF
      DeleteObject(hBitmap)
   END IF
END FUNCTION

The Dot.NET encapsulation doesn't do anything else, except it put it in a class.
