[DllImport("user32.dll")]
public static extern void
SetWindowPos(IntPtr hwnd, IntPtr hwndInsertAfter,
int X, int Y, int width, int height, uint flags);
function can do what:
it can set the relation between windows in your pc;
IntPtr hwnd: window handle you want to operate
hwndInsertAfter:
A handle to the window to precede the positioned window in the Z order. This parameter must be a window handle or one of the following values.
- HWND_BOTTOM
- (HWND)1
Places the window at the bottom of the Z order. If the hWnd parameter identifies a topmost window, the window loses its topmost status and is placed at the bottom of all other windows.
- HWND_NOTOPMOST
- (HWND)-2
Places the window above all non-topmost windows (that is, behind all topmost windows). This flag has no effect if the window is already a non-topmost window.
- HWND_TOP
- (HWND)0
Places the window at the top of the Z order.
- HWND_TOPMOST
- (HWND)-1
Places the window above all non-topmost windows. The window maintains its topmost position even when it is deactivated.

uint flags:
- SWP_ASYNCWINDOWPOS
- 0x4000
If the calling thread and the thread that owns the window are attached to different input queues, the system posts the request to the thread that owns the window. This prevents the calling thread from blocking its execution while other threads process the request.
- SWP_DEFERERASE
- 0x2000
Prevents generation of the WM_SYNCPAINT message.
- SWP_DRAWFRAME
- 0x0020
Draws a frame (defined in the window's class description) around the window.
- SWP_FRAMECHANGED
- 0x0020
Applies new frame styles set using the SetWindowLong function. Sends a WM_NCCALCSIZE message to the window, even if the window's size is not being changed. If this flag is not specified, WM_NCCALCSIZE is sent only when the window's size is being changed.
- SWP_HIDEWINDOW
- 0x0080
Hides the window.
- SWP_NOACTIVATE
- 0x0010
Does not activate the window. If this flag is not set, the window is activated and moved to the top of either the topmost or non-topmost group (depending on the setting of the hWndInsertAfter parameter).
- SWP_NOCOPYBITS
- 0x0100
Discards the entire contents of the client area. If this flag is not specified, the valid contents of the client area are saved and copied back into the client area after the window is sized or repositioned.
- SWP_NOMOVE
- 0x0002
Retains the current position (ignores X and Y parameters).
- SWP_NOOWNERZORDER
- 0x0200
Does not change the owner window's position in the Z order.
- SWP_NOREDRAW
- 0x0008
Does not redraw changes. If this flag is set, 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 the window being moved. When this flag is set, the application must explicitly invalidate or redraw any parts of the window and parent window that need redrawing.
- SWP_NOREPOSITION
- 0x0200
Same as the SWP_NOOWNERZORDER flag.
- SWP_NOSENDCHANGING
- 0x0400
Prevents the window from receiving the WM_WINDOWPOSCHANGING message.
- SWP_NOSIZE
- 0x0001
Retains the current size (ignores the cx and cy parameters).
- SWP_NOZORDER
- 0x0004
Retains the current Z order (ignores the hWndInsertAfter parameter).
- SWP_SHOWWINDOW
- 0x0040
Displays the window
