Closing a Window

Is it possible for me to close an I.E. window for example through my Visual Basic code. I found where I can get a list of open windows, etc. but I can't find anything on closing a window. Thanks for your help!!

'close MSIE Browser
'
Option Explicit

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

Private Const WM_CLOSE = &H10

Private Sub Command1_Click()


Dim MSIEhWnd As Long
Dim RetVal As Long
MSIEhWnd = FindWindow(vbNullString, "Microsoft Internet Explorer")
RetVal = SendMessage(MSIEhWnd, WM_CLOSE, 0&, 0&)

End Sub

Ok, I tried using your suggestions and it works perfectly for a Microsoft Excel Application. However when I put in the Microsoft Internet Explorer as you suggested it finds the windows handle, but it is not sending the 'Close' message. Any ideals??

OK, if that method doesn't work for you, try the TerminateProcess API which will Force a Process to Close, ie.

Private Declare Function FindWindow Lib "user32" Alias "FindWindowA" (ByVal lpClassName As String, ByVal lpWindowName As String) As Long
Private Declare Function OpenProcess Lib "kernel32" (ByVal dwDesiredAccess As Long, ByVal bInheritHandle As Long, ByVal dwProcessId As Long) As Long
Private Declare Function GetWindowThreadProcessId Lib "user32" (ByVal hwnd As Long, lpdwProcessId As Long) As Long
Private Declare Function GetExitCodeProcess Lib "kernel32" (ByVal hProcess As Long, lpExitCode As Long) As Long
Private Declare Function TerminateProcess Lib "kernel32" (ByVal hProcess As Long, ByVal uExitCode As Long) As Long

Private Const PROCESS_ALL_ACCESS = &H1F0FFF

Private Sub Command1_Click()
    Dim lHwnd As Long
    Dim lProcess As Long
    Dim lExitCode As Long
    
    'Get the Window Handle
    lHwnd = FindWindow("IEFrame", vbNullString)
    'Get the ProcessID
    Call GetWindowThreadProcessId(lHwnd, lProcess)
    'Get the Process Handle
    lProcess = OpenProcess(PROCESS_ALL_ACCESS, 0, lProcess)
    'Get the Exitcode
    Call GetExitCodeProcess(lProcess, lExitCode)
    'Terminate the Process
    Call TerminateProcess(lProcess, lExitCode)

End Sub
