I will try explain better...

I use CRYPTOR, then I have my data files encrypted. To read it, I have to use one function (crypt_register) before I try to read the file... If I didn't do it, I get the error 15 (Not a table).

So, I have this routine (Crypt_Register) in MAIN.EXE. After that I call CUSTOM.EXE to get some options... So, if other developer creates an EXE he could access my tables because MAIN.EXE already register it.

Then, I want to check if the EXE is the correct... It just works if you use cryptor or other solution like that... Because if you not use it, you can access dbf using excel, word, and VFP of course..

About SQL Server is not necessary to me at the moment... :-)
