VB 5,6 - Close window when you know its title - API

This is not my code, I found it on PSC and it was very useful to me.

VB Code:

'**************************************
' Name: Close a window
' Description:Close a window when you know the title of
' this window.
' Uses the API FindWindow and PostMessage.

Private Sub Command1_Click()
    Dim hWnd, retval As Long
    Dim WinTitle As String
    WinTitle = "Recycle Bin" '<- Title of Window
    hWnd = FindWindow(vbNullString, WinTitle)
    retval = PostMessage(hWnd, WM_CLOSE, 0&, 0&)
End Sub
