Thanks to much

If what you meant to ask was how to launch an application from another application you can use the SHELL function.
For example:
Dim RetVal
RetVal = Shell("C:\WINDOWS\CALC.EXE
For example:
Dim RetVal
RetVal = Shell("C:\WINDOWS\CALC.EXE
Not sure eactly what your asking either, but if you need to sit and listen for another application to open you can create a timmer and use the "FindWindow" api in there to listen for when the other application opens.
You can see this link for a description of FindWindow
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/winui/windows_03sn.asp
or search here on EE and you'll find lots of examples.

Dear all
I meant that myApp IS ACTIVATED AUTOMATICLLY WHEN OTHER APP IS ACTIVATED. For example myApp is activating when winword.exe is launching....ect
Thanks

Just to clarify. By activating, do you mean the application is being launched, or the application is already running and by activating you mean it is being set as the active window (being brought to the front)?
Also, in your example is it really a program like Winword that causes your application to "activate" or is it a program you control the source code to?

This code will check the Task Manager to see if the program you want to check is running.

You can add this to Word to have it start your app whenever a document is opened:
Private Sub Document_Open()
Shell("MyApp.Exe")
End Sub
This should probably be added to Normal.Dot's ThisDocument object's code area.
Private Sub Document_Open()
Shell("MyApp.Exe")
End Sub
This should probably be added to Normal.Dot's ThisDocument object's code area.

Logging use of executables in Windows
This handy little tip can be used to log the use of .exe, .lnk, .pif, .bat, and .com files on your computer. All it needs is a little registry tinkering. Place this code in a module, and set the project startup object to 'Sub Main'
Procedure
Sub Main()
If Command$ <> "" Then
Open "c:\apps\exelog.txt" For Append As #1
Print #1, Command$ & " " & CStr(Now)
Close #1
Call Shell(Command$, vbNormalFocus)
End If
End
End Sub
Registry Changes
The registry changes are:
HKEY_CLASSES_ROOT\exefile\
HKEY_CLASSES_ROOT\lnkfile\
HKEY_CLASSES_ROOT\piffile\
HKEY_CLASSES_ROOT\batfile\
HKEY_CLASSES_ROOT\comfile\
What happens it that instead of running the program directly, Windows calls our program, which logs filename and time, and then calls the program.

You could do it manually or you could do it from your program the first time you run it. I think after changes are done, PC must be restarted.

' ==========================
' Class: cRegistry
' Author: Steve McMahon
' Date : 21 Feb 1997
'
' A nice class wrapper around the registry functions
' Allows searching,deletion,modific
' of Keys or Values.
'
' Updated 29 April 1998 for VB5.
' * Fixed GPF in EnumerateValues
' * Added support for all registry types, not just strings
' * Put all declares in local class
' * Added VB5 Enums
' * Added CreateKey and DeleteKey methods
'
' Updated 2 January 1999
' * The CreateExeAssociation method failed to set up the
' association correctly if the optional document icon
' was not provided.
' * Added new parameters to CreateExeAssociation to set up
' other standard handlers: Print, Add, New
' * Provided the CreateAdditionalEXEAssocia
' to allow non-standard menu items to be added (for example,
' right click on a .VBP file. VB installs Run and Make
' menu items).

' ==========================
' Class: cRegistry
' Author: Steve McMahon
' Date : 21 Feb 1997
'
' A nice class wrapper around the registry functions
' Allows searching,deletion,modific
' of Keys or Values.
'
' Updated 29 April 1998 for VB5.
' * Fixed GPF in EnumerateValues
' * Added support for all registry types, not just strings
' * Put all declares in local class
' * Added VB5 Enums
' * Added CreateKey and DeleteKey methods
'
' Updated 2 January 1999
' * The CreateExeAssociation method failed to set up the
' association correctly if the optional document icon
' was not provided.
' * Added new parameters to CreateExeAssociation to set up
' other standard handlers: Print, Add, New
' * Provided the CreateAdditionalEXEAssocia
' to allow non-standard menu items to be added (for example,
' right click on a .VBP file. VB installs Run and Make
' menu items).

There is a simpler one, if you need it i would post it too.

Oops!, i don't know if that code works in Advanced Server.
Exewrap.exe should be YOUR app, so, what has to appears in registry should be:
"myApp.exe"1"%*

Dear Richie Simonetti
Follow your statements. I got the logfile that content all of applcations name has been activated. But when I try to put a form inside your code, like "Load (Frm1)", nothing happened. Could you one more time give a explain pls
Thank to much

I didn't understand your last comment. Where do you use "Load (Frm1)"?, a form with that name exists in your app?, what are you calling first, Main or frm1?
sorry.

Well, but the form never launch! so if I put your code between form load event then nothing is doing. ! Why the form could not be load ??? in sub main(), in form load () ???
This is so surprise
Thanhs to much
