salut
je suis en train de creer mon premier prog sous VB qui sera une interface graphique totalement personalisée. le probleme est que lorsque je lance un prog externe, celui-ci peut se mettre derriere mon interface or ce que je voudrais faire c'est que mon interface reste en permanence derriere n'importe quel autre programme.
y aurait il quelqu'un pour me venir en aide car si j'ai pas de solution je peux arreter tout de suite et dans ce cas j'aurais perdu des heures de prog pour rien (SNIFF !!!)
merci d'avance
et bonne prog

Il faut utiliser l'API SetWindowPos, voici sa description tirée du guide allapi :

The SetWindowPos function changes the size, position, and Z order of a child, pop-up, or top-level window. Child, pop-up, and top-level windows are ordered according to their appearance on the screen. The topmost window receives the highest rank and is the first window in the Z order.

Declare Function SetWindowPos Lib "user32" Alias "SetWindowPos" (ByVal hwnd As Long, ByVal hWndInsertAfter As Long, ByVal x As Long, ByVal y As Long, ByVal cx As Long, ByVal cy As Long, ByVal wFlags As Long) As Long

· hWnd
Identifies the window.

· hWndInsertAfter
Identifies 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
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
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
Places the window at the top of the Z order.
HWND_TOPMOST
Places the window above all non-topmost windows. The window maintains its topmost position even when it is deactivated.

· X
Specifies the new position of the left side of the window.

· Y
Specifies the new position of the top of the window.

· cx
Specifies the new width of the window, in pixels.

· cy
Specifies the new height of the window, in pixels.

· uFlags
Specifies the window sizing and positioning flags. This parameter can be a combination of the following values:
SWP_DRAWFRAME
Draws a frame (defined in the window’s class description) around the window.
SWP_FRAMECHANGED
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
Hides the window.
SWP_NOACTIVATE
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
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
Retains the current position (ignores the X and Y parameters).
SWP_NOOWNERZORDER
Does not change the owner window’s position in the Z order.
SWP_NOREDRAW
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
Same as the SWP_NOOWNERZORDER flag.
SWP_NOSENDCHANGING
Prevents the window from receiving the WM_WINDOWPOSCHANGING message.
SWP_NOSIZE
Retains the current size (ignores the cx and cy parameters).
SWP_NOZORDER
Retains the current Z order (ignores the hWndInsertAfter parameter).
SWP_SHOWWINDOW
Displays the window.

Ca te fera bosser ton anglais lol
