Closing Applications from VB - Need an ans ASAP

I am creating a program in VB 6 that opens other applications like Word, Excel, IE, etc. I used ShellExecute to open the files/applications. Now I need a way to fully close the applications after I am done using them.

Things I thought baout were FindExecutable, TerminateProcess, but have not reallyhad much luck in determining if they will work  good or not. Need some help fast!!!!!!!!1

What are you doing in the applications.  Can you do it under the application's VBA program control, or can you do it under program control from VB?

Use the following code

Private Declare Function FindWindow Lib "User32" Alias "FindWindowA" (ByVal lpClassName As Any, ByVal lpWindowName As Any) 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 Command2_Click()
    lngreturn = FindWindow(vbEmpty, Window Caption)

In this statement,

lngreturn = FindWindow(vbEmpty, Window Caption)

I know that you dim a var as long (lngreturn)

.. vbEmpty would be a null handle?
, and Window Caption - would that be the title of the application window to close?

 Could you give me a example putting in some fake vars or something. I understand the code, but dont really have a way of telling what I cana nd need to put in there.

Suppose you have opened Experts Exchange in Netscape communicator gold, the caption of the title window shows "Visual Basic Question - Netscape". Use this as the parameter as the window caption. If you open Word, the caption would be "Microsoft Word - Document1". Use this. The exact caption of the window should be used.

I tested the given code with the Notepad.

I used

lngReturn = FindWindow(vbEmpty,"Untitled - Notepad".

It worked with me.

Okay, with that in mind that you need to use the exact caption of the window, my program opens ANY file(s) in almost any application. So how can I know what file is opened and what the caption reads for this to work properly? I cant.

Isnt there any other API calls that can close applications.

App.PrevInstance will tell me how many instances of an app are open, is there any other property like that that can close the applications down though?

You have an array which will tell you what all windows are opened using your applications.

Use EnumWindows to get all the parent windows and loop through them to close the window which you want to close.

Redim the array

Hate to ask, but do you happen to have any code examples of this. I have not reached this far into API calls for a while, and need a little help.
