Is it possible to get the stack trace information in Visual Basic 6.0. I mean I want to find out the function name and exact line that causes the error similar to .NET stack trace. I have created an ActiveX DLL which works fine in my test environment but it throws an error in production environment(error : 91-Object variable or With block variable not set). Any help on this much appreciated.

This is a good way to do it - an answer on the existing duplicate question. Use MZTools to insert the error handlers automatically
Alternatively, you can debug your built DLL in the production environment using WinDBG, a free standalone debugger from Microsoft. Compile your DLL into native code with symbols (create PDB files).
Here's a 2006 blog post by a Microsoft guy about using Windbg with VB6, and 2004 blog post by another Microsoft guy with a brief introduction to Windbg.
