Closing Widows, Closing an app

How does one detect if a certian application is opened, and how do you close it from VB?

I have an ExitWindowsEx procedure that shuts the computer down at a certian time (closing time :D ). When the computer is rebooted, the "Windows was shut down improperly" comes up, and scandisk runs. How do I "shut down properly" to prevent this?

u can use findwindow to detect if an application is open, then SendMessage with wm_close as the message to close it :)

VB Code:

Private Declare Function FindWindow Lib "user32" Alias "FindWindowA" (ByVal lpClassName As String, ByVal lpWindowName As String) As Long
Private Declare Function PostMessage Lib "user32" Alias "PostMessageA" (ByVal hwnd As Long, ByVal wMsg As Long, ByVal wParam As Long, ByVal lParam As Long) As Long
 
Private Const WM_CLOSE = &H10
 
Private Sub Command1_Click()
Dim WinWnd As Long
    WinWnd = FindWindow(vbNullString, "Caption Of Open Application")
    If WinWnd > 0 Then  'it is running, so close it
        PostMessage WinWnd, WM_CLOSE, CLng(0), CLng(0)
    End If
End Sub

yeah, that's the one :)

I'm interested in this too. But does this work for app/windows that normally throw up modal dialogs like "Do you want to save..." before closing?

yes, but that is a child window, you need to use FindWindowEx to get the handle of it...
