Or use code profiling tools. They tend to be more accurate anyway and many of them can pinpoint the exact line causing performance problems without having to manually modify the original code. That is better than guessing as to where the problem lies. -- Thomas Hruska CubicleSoft President Ph: 517-803-4197 *NEW* MyTaskFocus 1.1 Get on task.
