Hi, Saw similar posts so asked the question there.. Sorry for the trouble.. When i comment the code for running the script, my code works fine. So does not look like a problem with the code. I have pre-compiled and stored the context handle and script handle. later in my application, i get the context and try to run the script in the context. This is giving me a performance hit. I have to run the script on a large number of object without the performance hit.
