FATAL ERROR: Unhandled c0000028h. Exception at 3AD9A48h

[Craig_Patrick]

This has been a recurring error that occurs while manipulating a combo box within a custom application. I am unable to produce the error consistently though. If my code is the problem, I would like to fix it, however I am unsure:

What is a fatal error?

What is an Unhandled c0000028h?

What is an exception at 3AD9A48h?

Any help would be appreciated!

It's just a blanket error handler that, in most cases, lets you know there was an unhandled exception (e.g.: a problem for which there is no error handler), and rather than the application just vanish from the screen, it tries to save face a little by stopping and telling you it can't continue. Kind of like the Windows BSOD. On some occasions, it's followed by a "Do you want to try and save your work" dialog (to which you should generally say NO), and sometimes there is no fatal error message, AutoCAD does simply disappear from the screen.
