3rd Party Component brings down the IDE. How do I prevent this?

I am having to use a 3rd party ActiveX DLL in my VB6 application. However, now that I've included the DLL in the references and used it in code, every time I quit my app, it also quits VB6.

I don't see anything in the logs or event viewer that would suggest why this is happening.

Is there anyway to prevent this?

Btw, I have contacted the vendor, but they are focused on their .NET products, it seems.

Just to close this question out... After spending significant time trying various things I ended up writing code that unloaded the control, paused for 5 seconds and then quit app. That seemed to do the trick.

Ouch. I feel your pain.

Can you switch to a .Net component, and use it from VB6 via interop? I.e. write a COM-visible wrapper in VB.Net?

I'm not a VB6 programmer by trade. I just mess around with the stuff. I have heard of this scenario referred to as sub-classing. Run a search on pscode.com. They have code and tutorial examples about how to prevent it. Good luck.

Try switching DEP off for VB6.exe only or altogether.

Also, this might be a license checking issue i.e. registry permissions -- try running VB6 IDE as Administrator (right click->Run as Admin)

You may not be using the component correctly by missing specific initialization or termination calls, which has the affect of bringing down VBIDE. This usually happens when the third-party component or your application make Win32 calls.

I have had a few applications that I ran them through the debugger, they always terminated VBIDE. Yet, running the Release or Debug versions normally, resulted in the applications working just fine.
