Using NetAddUsers

Using NetAddUsers

I created a program to Add User Account to my NT Server. It reads from a text file which provides the user info. Everything works fine, except that the user’s full name takes the value from the user id. I used USER_INFO_2 and I specified the flag usri2_full_name to take the values from the text file (the value has been changed to unicode). This really puzzles me as the rest works fine. Please advice.

It’s really hard to say without seeing both the code and the declares, but there are lots of way to go wrong with the unicode functions, and only a couple of ways to do it correctly. The following VB code will allow you to add users, including full names, to either the local machine or the server.
