Basically its not possible, but...

From an exe you have to put context information in your code.

This can be

(a) a global which sets a context string
(b) a stack class which adds a context every time you do a call, and removes the context every time you return

option (b) can be a performance hit. option (a) doesn't always give you the info you need. so its down to what your requirements are.

From VB you can set tools - options - break on all errors. Then the debugger will break on the error line. I guess you knew that already ?

I use third party tool named CodeSmart 2003. The error handler's written with this tool can tell me the exact line and place of the error.

The undocumented Erl() function will return the line number where the error occured.  For this to work you have to use line numbers.  If the line with the error does not have a line number, Erl() returns the last numbered line before the error.  This function was documented in earlier versions of VB.
