However, you'll need to use the GetDC() API call to convert the object's hWnd into a DC. Try this: <code>Declare Function GetDC Lib "user32.dll" (ByVal hWnd As Long) As Long</code> When you're finished with the DC, use ReleaseDC to free up resources: <code>Declare Function ReleaseDC Lib "user32.dll" (ByVal hWnd As Long, ByVal hdc As Long) As Long</code> Yes, can use the effect on a non-DC object.

The DIB code above should work on any control that has an hDC property. You'll have to tweak the functions themselves a bit (as they currently accept Picture Boxes, then extract the hDC from there), but there is no reason that you can't use DIB sections to modify the pixel data returned from any hDC.
