If window open then close it

[rino_2]

Hi,

Does anybody know how I can detect if there is a window open with the name “window” and then close that window if it is open? I’m quite sure this can be done with the windows APIs but I don’t have a clue how? Thanks

Try this:

Private Declare Function FindWindow Lib "user32" Alias "FindWindowA" (ByVal lpClassName As String, ByVal lpWindowName As String) As Long
Private Declare Function SendMessage Lib "user32" Alias "SendMessageA" (ByVal hwnd As Long, ByVal wMsg As Long, ByVal wParam As Long, lParam As Any) As Long
Const WM_CLOSE = &H10
Const WM_DESTROY = &H2

Private Sub Command1_Click()

    'Get the hWnd of the Window named Calculator
    MyHwnd = FindWindow(vbNullString, "Calculator")
    'If it's found then close it
    If MyHwnd <> 0 Then
        SendMessage MyHwnd, WM_CLOSE, 0&, 0&
        SendMessage MyHwnd, WM_DESTROY, 0&, 0&
    End If

End Sub

        SendMessage MyHwnd, WM_CLOSE, 0&, 0&
        SendMessage MyHwnd, WM_DESTROY, 0&, 0&
    End If

End Sub

a few days ago I tried this with IE,
I used the class IEFrame, and all it did was disable IE, and it wouldnt allow me to close it normally i had to end-task it.
