PRB: C2660

ID: Q87636

The information in this article applies to:

The Microsoft Foundation Classes (MFC), used with:
- Microsoft Visual C++ for Windows
- Microsoft Visual C++ 32-bit Edition

SYMPTOMS

When using the Microsoft Foundation Classes (MFC), the following error may occur when making a Windows application programming interface (API) call from within a member function of a window class:


   C2660: 'function' : function does not take 'number' parameters

CAUSE

Many of the Windows API calls are accessed in the Microsoft Foundation Classes through member functions of the same name as the API calls. This means that the name will be recognized, but because most member functions require fewer parameters than their API counterparts, the C2660 error occurs.

RESOLUTION

Either of the following two methods eliminates the error:

Adjust the function call to conform to the format of the member
```
   function call.

   -or- 
```

Use the scope resolution operator (::) to tell the compiler to look for the function name in the global name space.
