Class and namespace question

I thought if a class, e.g. DataHelpers.vb, is in a project, the other files in the project don't need to actually import it to use it. But this doesn't seem to be the case. I do have to import it. Is this a namespace problem or is it correct behavior? Thanks.

If they are all under the same namespace then there should be no need to import anything.

If the class is under a different namespace, or a subnamespace, I believe you will need to import it, or use the fully qualified name.

Thanks crptcblade. The only namespace I find is the Root Namespace for the project. I did add the class to the project from another project, but it did the same thing there. Is this a difference between VS 2002 & 2003?
