This function changes the position and dimensions of the specified window. For a top-level window, the position and dimensions are relative to the upper-left corner of the screen. For a child window, they are relative to the upper-left corner of the parent window’s client area.

Syntax
BOOL MoveWindow( HWND hWnd, int nX, int nY, int nWidth, int nHeight,
BOOL bRepaint);
Parameters
hWnd
Handle to the window.
X
Specifies the new position of the left side of the window.
Y
Specifies the new position of the top of the window.
nWidth
Specifies the new width of the window.
nHeight
Specifies the new height of the window.
bRepaint
Boolean that specifies whether the window is to be repainted. If this parameter is TRUE, the window receives a WM_PAINT message. If the parameter is FALSE, no repainting of any kind occurs. This applies to the client area, the nonclient area (including the title bar and scroll bars), and any part of the parent window uncovered as a result of moving a child window. If this parameter is FALSE, the application must explicitly invalidate or redraw any parts of the window and parent window that need redrawing.
Return Values
Nonzero indicates success. Zero indicates failure. To get extended error information, call GetLastError.
Windows CE Remarks
The bRepaint parameter is ignored and is assumed to be FALSE.
Remarks
If the bRepaint parameter is TRUE, the system sends the WM_PAINT message to the window procedure immediately after moving the window (that is, the MoveWindow function calls the UpdateWindow function). If bRepaint is FALSE, the system places the WM_PAINT message in the message queue associated with the window. The message loop dispatches the WM_PAINT message only after dispatching all other messages in the queue.
MoveWindow sends WM_WINDOWPOSCHANGED, WM_MOVE, and WM_SIZE messages to the window.
