ShellExecute: Open and close IE browser

[Rajat]

Hi,

I am trying launch the IE browser and call a certain asp page and then close the browser after a few seconds. I am successful in launching the browser and calling the asp page. But for some reason, I am not able to close the browser. I must be passing the wrong window handler? Any suggestions?


private Declare Function ShellExecute _
Lib "shell32.dll" Alias "ShellExecuteA" _
(byval hwnd as Long, byval lpOperation _
as string, byval lpFile as string, byval _
lpParameters as string, byval lpDirectory _
as string, byval nShowCmd as Long) 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 Form_Load()
Dim r as Long
Dim lngResult as Long

r = ShellExecute(0, "Open", "C:\PROGRA~1\INTERN~1\IEXPLORE.EXE", "http://localhost/members/include/Use...p?schedule=yes", 0, 1)
lngResult = SendMessage(hwnd, WM_CLOSE, 0, 0)

End Sub




Thanks,

Rajat

try this TerminateTask function:

call it like this:

TerminateTask ("Title") ' Where title is the title of the app that you see on the title bar. for example, "Internet Explorer" or the local page name.



Put the following in a module:

public Declare Function EnumWindows Lib "user32" (byval wndenmprc as Long, byval lParam as Long) as Long
public Declare Function GetWindowText Lib "user32" Alias "GetWindowTextA" (byval hWnd as Long, byval lpString as string, byval cch as Long) as Long
public Declare Function SendMessage Lib "user32" Alias "SendMessageA" (byval hWnd as Long, byval wMsg as Long, byval wParam as Long, lParam as Any) as Long
public Const WM_CLOSE = &H10

private Target as string

' Check a returned task to see if we should kill it.
public Function EnumCallback(byval app_hWnd as Long, byval param as Long) as Long
Dim buf as string * 256
Dim title as string
Dim length as Long

' get the window's title.
length = GetWindowText(app_hWnd, buf, len(buf))
title = Left$(buf, length)

' See if this is the target window.
If InStr(title, Target) <> 0 then
' Kill the window.
SendMessage app_hWnd, WM_CLOSE, 0, 0
End If

' Continue searching.
EnumCallback = 1
End Function

' Ask Windows for the list of tasks.
public Sub TerminateTask(AppName as string)
Target = AppName
EnumWindows AddressOf EnumCallback, 0
End Sub
