To be honest: I don't have the slightest idea! How should I or anyone else know from the practically no information you provided? We need much more concrete information and in particular more concrete code than just a single line.

For starters, here's a thread that (AFAICT from what I know by now) is topically related and perhaps already provides some inspiration: http://www.codeguru.com/forum/showthread.php?t=508025

And please use code tags when posting code to preserve proper code formatting. Not using them was harmless with your one-liner, but the initial post of the thread I linked to perfectly demonstrates how bad it can get without them.
