Please help with ActiveX exe

[PaulB]

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 ?

[PaulB]

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 ?

[peet]

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

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

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

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?

[crptcblade]

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