The MoveWindow 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.
BOOL MoveWindow(
HWND hWnd, //
handle of window
int X, // horizontal position
int Y, // vertical position
int nWidth, // width
int nHeight, // height
BOOL bRepaint // repaint flag
);
Parameters
hWnd
Identifies 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
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
If the function succeeds, the return value is nonzero.
