I need use this fuction to support a legacy aplication with two end-users GUI: A Fox EXE and a ASP.NET Site, so i need share a lot of things. Of couse, i use the VFP.NET function package, and this help a lot, but i need use this function or some semi-equal replacement.

If you are not a VFP dev, look for SYS(2015) in MSDN Help. This function return a unique string like _0IR0O0IU9 always 10 char fixed, start always with '_' and the rest don't know how...

Thanks
