Now, I'm hoping this is just some stupid mistake that I'm making because I'm new to the VC++ 2005 compiler/IDE. I have defined a base class and I'm attempting to create a child of that class. However, when I try to compile the child class, I get an error that the base class is undefined. Both source files are in the same project and even when I right click on the base class in the child class and select "go to definition", it brings me right to the definition of the class. Please fix my ignorance. -Jeff

Is the definition of the base class visible to the child class via a header?

And that's the embarrassment I get for needing so much sleep. Thanks SiCrane...especially for that fast reply.
