>As said several times, you can't use structures that contain pointers. It's useless to try to do it (or to convert something) using only FoxPro language. The strings in the structure you're talking about are in fact pointers to strings.

So, am I right to say that we can only use structures which deals with non pointers only like SetSystemTime()?

We are trying to find a workaround for this. Right now, we have been able to make NetUserDel() works but we couldn't with NetUserAdd(). Is the best approach to build a C program, for that specific function, that we can call from Visual FoxPro?
