SetRect sets the position and size of a rectangle. The two coordinates specified are the upper-left and lower-right corners of the rectangle. The function returns 0 if an error occured, or 1 if successful.

lpRect

The rectangle to set the position and size of.

X1

The x coordinate of the upper-left corner of the rectangle.

Y1

The y coordinate of the upper-left corner of the rectangle.

X2

The x coordinate of the lower-right corner of the rectangle.

Y2

The y coordinate of the lower-right corner of the rectangle.

Example:

' Set rectangle r to represent the rectangle (20,30)-(100,50).  Note
' that using this function is more efficient and takes less room than setting the rectangle's
' four member values individually.
Dim r As RECT  ' the rectangle to set
Dim retval As Long  ' return value

retval = SetRect(r, 20, 30, 100, 50)  ' r now represents (20,30)-(100,50)
