C#.net opened app before close event

[Dirar0D44]

I wrote a winform app that opens a pdf file using Acrobak SDK. basicly this is my app:

mApp = new AcroAppClass();
avDoc = new AcroAVDocClass();

String sourceFileStr = @"sample.pdf";

avDoc.Open(sourceFileStr, "");
pdDoc = (CAcroPDDoc)avDoc.GetPDDoc();

mApp.Show();

I am trying to catch the event before closing the opened application window or even after close. I couldn't find a way to to so. Any hints please?

There are no events for COM programming in Acrobat. You would need to write a C++ plug-in for them.
