However, for a stateless COM application like a web app (vfp mtdll), ALWAYS use ComReturnError. This is a good rule-of-thumb for web apps.
>In addition to my previous reply, i just look at your code and remembered of another rule you should follow:
>
>- NEVER use ComReturnError() Using it will cause your component to stop executing and return the control to the client, again bypassing any Garbage collection method you may have. Since you never know where an error occurs in the code, it would also be impossible to predict the effect of stopping code execution.
