Declare Function CopyRect Lib "user32.dll" (lpDestRect As RECT, lpSourceRect As RECT) As Long

Platforms: Win 32s, Win 95/98, Win NT

CopyRect sets one rectangle equal to another. This is done by duplicating all of the source rectangle's member values to the corresponding ones in the target rectangle. This is faster than setting all four values manually in your code. The function returns 0 if an error occured, or 1 if successful.

lpDestRect

The target rectangle to set.

lpSourceRect

The source rectangle.

Example:

' Set the source and target rectangels equal to the rectangle ' of the window by copying the source to the target Dim source As RECT, target As RECT  ' source & target rectangles Dim retval As Long  ' return value ' Get the rectangle of Form1 into source retval = GetWindowRect(Form1.hWnd, source) ' Copy source into target retval = CopyRect(target, source)
