I have a windows form that has four input text boxes. The input for each of these must be integers. Is there a way (e.g. property) that I can set which will only allow the user to enter intergers??? Thanks for any help.

I looked at the zip file which was referenced in the previous reply. It appears that the code simply creates the pipe process in MFC/C++ code which is then put into a DLL and imported into the C# program. Athough I am sure that this works, I was really looking for the C# compliment to pipe processing. Once my C# GUI process spawns my C# process, is there any way for the two to pass information back and forth. I am not very familiar with channels, threads, etc. so I don't know whether these would be my solution. Once again, any assistance/direction is greatly appreciated.

Thanks so much. I knew that it could probably be done but I would have never found it. This looks like something I can certainly use.
