User Privaleges ...

[alex_read]

Sure I asked this one before

I know how to get a username / log on, but is there any way to tell if a user has admin / install rights on a PC please?

Thanks All !

I have a sample for this somewhere Alex, I had to reformat my machine yesterday, so it may take me a wahile to find - but i'm digging as I write! bear with me...

Yey!

Don't think I got an answer last time so didn't think it was possible.

No real rush, post when you're ready & thanks !

here ya go!

look for the netuser sample, I'm sure you can butcher the code here to just rip out the priviledge info bits (if ya need anything else just lemme know) I need this code too for some install packages I'm doing, and im going to rip those bits out at some point today, so If ya wanna wait for mine i'll post em later on...
