Using Registry

I got a module that has all of the various api calls to access the registry with (RegCloseKey, RegQueryValueEx, etc). I got these from my VB book, but the problem is when I run my program and it gets to a the function associated with the registry calls it says "Ambiguos Name". So if you have the module that you use for all your registry accessing i'll be thankful if you can share it with me or point me to one :).

Thank you

Check to see that you don't have two functions or subs with the same name.
