This was all I needed. Thanks for the helps anyway because it did helped me to use for other things. The thing I didn't realized was the InputMask was '999999', which do not allow spaces anywhere, not even in betweens, so that takes care of everything. The tests I did was from the Command Window. Thanks again.
