Network Drive Mapping in SQL Database Project

Today I tried to add a feature to map to a network drive in a .Net SQL database projjavascript:void(0)ect. The codes is based Windows API functions to map to a network drive. It works fine as a windows application. However, when I tried the same codes in my SQL database project, it fails to map to a network drive. I got an windows exception about something like a log on session failure (I need to use a user and password to make a map drive). The source codes is based on aejw.com's codes.

That's too sad. Maybe there are some other ways to get around this. One way is to run an external process to make a mapping by starting a process from SQL server. Another way may be something like described in this discussion on topic of C# Mapping a network drive, running a process of net.exe directly in C#.
