RE: While Loop with a StreamReader process included for fun

Manish,

Thanks for the help, however, I have already confirmed the file name are
correct and don't contain any errors. I have used the internal function to
automatically load an array with files within a directory that meet a certain
criteria.

I think the error being returned has nothing to do with the actual error.

If you have any further thoughts let me know.

Yours sincerely,

William Foster
