I completely understand. I haven't found the limit yet and as I said, I dont know if DJ is limiting it in any way. It is a question he will have to answer, but knowing that the underlying controls dont limit it to anything unreasonable would help to know. The control he is using is probably based on an int32 which has a max value of 2,147,483,647. Even if this were limited to int16, its max value is 32767 plus or minus. I dont know of anyone ever having an issue with adding too many items to this control, but the limiting factor wouldn't be the control on the form, but the dictation library (IMHO).

Understanding the underlying limitations helps to get an idea of the answer without having a concrete answer.

Ah-Ha, very cool. I didn't think about those int values.

Thank you all for all the answers.
