prevent closing of an application, without closing another application launched by it

[kmr506]

Hi All,

I have a VBApplication(Exe) which is launched by cilcking on a link from a purchased product.

The application which is launched is a data entry form, and it updates a database as well as pass some data back to the application which has launched it through DDE calls..

My requirement is , after launching the VB Exe I want to stop users from exiting the Launcher Application without closing the Launched Application.

Any suggestions/ solutions are most welcome....

Thanks in Advance

Kiran
PS: I have no access to change/Modify the Purchased Product..all i can play with is the VB exe i am creating..

It may not be the best answer, but hat if the VB app looks every second or so to make sure the host app is running. If it is not, kill the VB app.

You can you FindWindow API function to determine that the host app running or not.
It just like this:

Public Declare Function FindWindow Lib "user32" Alias "FindWindowA" (ByVal lpClassName As String, ByVal lpWindowName As String) As Long

Private sub GetHostName()
     Dim sHost as string
     Dim hRet as long 
     
     sHost=<your host app>
     hRet=FindWindow("",sHost)
     If hRet <> 0 then
          'App running
          'Do ur stuff
     else
          'App not running
          'do ur stuff
     endif
end sub
