I want to be able to detect how many instances of Internet Explorer are running on a computer. For instance one window navigates the web and if another window pops up I want to detect that another instance of Internet Explorer is open and use this code to close it:
If there is an easier way to do what I'm attempting to do, which is only have one instance of Internet Explorer open at one time and close all the other windows that may pop up then I am open for suggestions.Code:
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
Thanks,
Publius
