Error line 392 in eventoracle.cpp when using activeX callback vi.

[ktsoft78]

I am using an activeX control built in VC6.0. I followed the instructions to handle the activeX event using the Reg Event Callback node. It is being handled because I have a message box within the handler that does appear. But after the handler executes, LV crashes with the statement that eventoracle.cpp failed at line 392.

Hello,

If you post a small piece of code that can reproduce this crash I would be happy to create a report of the crash and submit it to our LabVIEW developers. I can also take a look at the LabVIEW code and see if there is any possible workaround to avoid this crash.

I found that the issue is not the ActiveX event, but where is the event fired from in the ActiveX control. I have a worker thread that calls the parent thread's method to fire the event. If I move the firing of the event outside of this worker thread, I have no problems getting handling the event.
