VC ++：奇怪的编译器错误

Question

I'm working in visual studio with DirectX and today I've gotten some weird compiler errors that don't make any sense (to me at least)...

These are the errors I get:

error C2143: syntax error : missing ';' before '.' error C2059: syntax error : ')'

I've double checked my code and didn't spot any typos/mistakes (I could be wrong...)

I'm hoping that someone can tell me what the error usually means and where to look...

I'll put some code below with the indication of the line where the errors occur (in case you want to check)

In C++, the scope resolution operator is :: , not . ; consequently, you need to use Vertex::PosTex rather than Vertex.PosTex .
