You can also simply use:   UserInfo.UserID()

The answer to your 2nd question is Yes.  Here is a good way to find answers to your coding questions.

1.   Find a CORE page that is doing something similar to what you are looking for.
2.   Look at the code.

Contrary to what others may say, ALL the answers to nearly every question are in the existing code.

Ok, I don't know how much head way I'm having but this is a little update. First, I've been constantly having the old can't copy dotnetnuke.dll in the VSWebCache. I ran through EVERY possible answer out there (been working that issue for weeks). Finally I just said, #$@(# it and opened up the Config Manager on the solution and unchecked the build box on every project but the ones I'm building. Simple reasoning, DNN works, I sure in the heck ain't changin' it so why keep building it much less cluttering up the results of what I want to see with DNN stuff. Kind of like setting my SQL registration not to show system tables and stuff. So with all that out of the way I was able to concetrate on the sill issue of the UserId. Just as a reminder I'm a Newbie. Yes I know lets all stop laughing now ;p I'm also working with a web app that is written in C#. Basically what I want to do is change all the aspx pages to ascx pages to make modules out of them and then strip out all the excess stuff but the relevent tables and buttons. I then need to make the existing app that uses the variable named intUserId get it's value from DNN's currently logged in user's User ID.  So after all the messing around I figured out 2 lines that would actually work without giving me some errors about method out of context or something like that. These are the 2 lines I added that I put in.

int UserID = Int32.Parse(DotNetNuke.Entities.Users.UserController.GetCurrentUserInfo().ToString());

int intUserId = UserID;

I've even tried many other types of combinations and get no joy. The wierd thing is I can no longer tell if I'm making any headway. Every time I check the module by looking at the browser I keep getting the same error and no new info. Any clue as to what I'm doing wrong.
