getentity loop problem

[Anonymous]

I am using the getentity method in a continuous loop. I want the user to be able to select entities until they press the escape key. Similar to the ddedit command or something. When the user presses the escape key an error is thrown. No problem I can't the error and end the cycle. The problem is that the escape error is the same error that is thrown when you select nothing. So I can't tell the diference between a bad pick and an escape. Anybody have any ideas?

Use a MsgBox to confirm that they want to exit the
routine?

After the error occurs, inspect the value of the ERRNO
system variable. ThisDrawing.GetVariable("ERRNO") will
return 7 for a missed pick, 52 otherwise.

That't a good Idea. I currently have it set up so the user has to type quit to exit, but I would like this routine to act more like a built in AutoCAD routine.

Thanks a lot Frank that did the trick. I guess now I don't understand why the err object can't tell the difference. Do you know what's going on behind the scenes.

The Err Object and ERRNO are two totally separate things.
