Visual Studio not recognizing certain classes

I keep getting the error: 

error C2146: syntax error : missing ';' before identifier 'mCameraFrame'

for the line of code:

Frame mCameraFrame;

So clearly my frame class isn't being found somehow. I have the frame.h header file (which defines the Frame class) directly included in this file. Why doesn't visual studio recognize it?

Figured I'd report back to anyone that's interested. The problem was that the Frame class that was supposed to be definining mCameraFrame was in a different namespace, so all I had to do was "using namespace ....;". Doh! :P

The error is coming from previous lines of code, possibly in a header file.

For example:

struct foo
{
    int a;
}

Frame mCameraFrame;

Notice the missing ; after the }? That makes the Frame legal as an instance of the structure, but now there's a missing ; before mCameraFrame, resulting in the kind of error you reported.

The compiler can't report a missing ; after the } because it has no way to know there's supposed to be one there, since the Frame that comes after it is perfectly legal.

It's not unusual for a single missing ; or missing } to result in errors reported many lines later than the actual problem, sometimes hundreds of them.
