CDialog and Cdialogex link error

Hello,

I have a project in Visual C++, and it works well in Visual Studio 2005. I convert it to Visual Studio 2010, and everything went well, compiled and linked wihtout problems.

Then, I tried to add a new Dialog; the system added a Cdialogex (instead of the Cdialog that I used to use). I didin't realize that, and I go ahead, then compiled, and then I got a link error on all my previous Cdialog that I have:

Error 80 error LNK2001: sÃ*mbolo externo "public: virtual void __thiscall CDialog::OnOK(void)" (?OnOK@CDialog@@UAEXXZ) sin resolver D:\proyectos010\MVFlexCGPlayer\VideoPlayConfigurationLE.obj

Any ideas about the problem?

Did you try to "Rebuild All" (rebuild the project)?

And did you use an extern?
