Using SendMessage to minimise another app

Hi all,

I'm trying to co-ordinate the windows of a multi-exe application.

From one exe, I can launch another exe (via Shell(), and work out the hWnd from the PID) and then kill it again using SendMessage(hWnd, WM_CLOSE).

What I want to do is minimise the windows of both exe at the same time (eg, when one is minimised, it tells the other one to minimise as well).

I can't find a suitable WM_ message in the API.
Suggestions anyone?

Private Declare Function ShowWindow Lib "user32" Alias "ShowWindow" (ByVal hwnd As Long, ByVal nCmdShow As Long) As Long
Private Const SW_MINIMIZE = 6

Call ShowWindow(hWnd, SW_MINIMIZE)

try this :

Declare Function CloseWindow& Lib "user32" (ByVal hwnd As Long)

Minimizes the specified window. The window is not destroyed.


p.s you can shell with minimize option.

Nice one! Exactly what I needed.

I assumed (incorrectly...) that there would be a WM_MINIMIZE, like the WM_CLOSE.

Thanks very much to everyone who contributed.
