Tough one.. minimize an external application :S

I wonder if it is possible to minimize an external application , like with its handle or something (not sure how to get that either)..


any help to get me on the way is welcome...
:wave:

I've not used this code for a long long time (its in vb6 as well sorry) but it may help you.

Basically i can't remember the specifics of how it works just what i used to use it for!

Basically if it checks if the app is open and then if activates (if desired).

VB Code:

Private Const SW_HIDE = 0
Private Const SW_SHOWNORMAL = 1
Private Const SW_NORMAL = 1
Private Const SW_SHOWMINIMIZED = 2
Private Const SW_SHOWMAXIMIZED = 3
Private Const SW_MAXIMIZE = 3
Private Const SW_SHOWNOACTIVATE = 4
Private Const SW_SHOW = 5
Private Const SW_MINIMIZE = 6
Private Const SW_SHOWMINNOACTIVE = 7
Private Const SW_SHOWNA = 8
Private Const SW_RESTORE = 9
Private Const SW_SHOWDEFAULT = 10
Private Const SW_MAX = 10

        Case Else:          strClassName = ""
    End Select
    
    If strClassName = "" Then
        lngH = apiFindWindow(vbNullString, strAppName)
    Else
        lngH = apiFindWindow(strClassName, vbNullString)
    End If
    
    If lngH <> 0 Then
        apiSendMessage lngH, WM_USER + 18, 0, 0
        lngX = apiIsIconic(lngH)
        
        If lngX <> 0 Then
            lngTmp = apiShowWindow(lngH, SW_SHOWNORMAL)
        End If
        
        If fActivate Then
            lngTmp = apiSetForegroundWindow(lngH)
        End If
        
        fIsAppRunning = True
    End If
fIsAppRunning_Exit:
    Exit Function
fIsAppRunning_Err:
    fIsAppRunning = False
    Resume fIsAppRunning_Exit
End Function

if you notice the line

VB Code:

lngTmp = apiShowWindow(lngH, SW_SHOWNORMAL)

why not change it to

VB Code:

lngTmp = apiShowWindow(lngH, SW_MINIMIZE)

or use one of the other constants and see what happens.

oh yeah i think to get the windows handles you can use spy++??

hope it helps?
