Please help with ActiveX exe

Hi

I have a program that instansiates an ActiveX exe when it runs. Sometimes, if my program is busy, opening a recordset for instance, and I end my programs task, the ActiveX exe remain running.

Is there a way to ensure that my ActiveX exe quits whenever my client program quits, crashes etc.?

Thanks.

set the object to nothing in your main forms unload event ?

Thanks for your reply.

I do set the object to nothing when my application is closed normally, but if it crashes, my ActiveX exe keeps running. I need it to close if my application is stopped abnormally.

so the main form is not unloaded when the app crashes ?

forget I said that... tested it ... it does not unload.

then my answer is, I do not know the answer.... :blush:

You could pass in the hWnd of the calling form, then periodically test if the window still exists using IsWindow.

VB Code:

Private Declare Function IsWindow Lib "user32" (ByVal hwnd As Long) As Long

That's a really cool idea...

...but is it not possible that the hWnd of a form can change during the course of the programs execution?

No. Unless you are dealing with another instance of the form, it will remain constant until the form is closed.
