MoveWindow moves a window to a new location. In addition to moving it, this function also changes the window's size to a new width and height. The function returns 1 if successful, or 0 if an error occured.

hwnd

The handle of the window to move and resize.

x

The x-coordinate to position the upper-left corner of the window at.

y

The y-coordinate to position the upper-left corner of the window at.

nWidth

The width in pixels to resize the window to.

nHeight

The height in pixels to resize the window to.

bRepaint

If 1, updates the screen to display the window at its new position. If 0, does not update the screen to reflect the move (the window will appear to be unmoved but will actually be at its new location!).

Example:

' Move window Form1.  Set its upper-left corner to the point (200, 150).
' Change its size to a width of 175 and a height of 300.
Dim retval As Long  ' return value

' Move the window and make sure it's redrawn at its new position.
retval = MoveWindow(Form1.hWnd, 200, 150, 175, 300, 1)
' (If the last value had been 0, the window would have appeared to be unmoved!)
