This is normally caused by making a mistake with some pointer or writing beyond the end of an array. Use the debugger and/or codeguard to debug your program.

Eelke is correct and more specifically, since the AV occures in vcl60.bpl, what most likely is happening is that a class method is being called before the object has been constructed or after the object has been deleted. Quote: and what can i do? The most common reason this happens is when one uses OnCreate and/or OnDestroy. If you are using either of those events - don't: http://www.bcbdev.com/articles/suggest.htm#oncreate Otherwise you'll need to use some sort of debugging method to isolate the problem and post a more specific question. ~ JD Back to top george Guest Posted: Wed Apr 21, 2004 10:52 am    Post subject: Re: what's wrong?
