Called by the wizard to verify that the user can add an ATL class to the project.

Syntax

  
      function CanAddATLClass(   
   oProj,   
   oObject    
);

Parameters

oProj
The selected project.

oObject
The selected object. In this case, the current project.

Return Value

true if the class can be added; false if the user calls the function for a project that is not an ATL project and does not have ATL support.

Remarks

Called by the wizard to verify if the project is compatible with the code wizard that is about to be run (in other words, it can accept an ATL class).

The wizard calls this function when the parameter PREPROCESS_FUNCTION is in the project control's .vsz file and checks if the Visual C++ Code Model is available. If the code model is not available, the function reports an error and returns false.

Example

// Determine if an ATL class can be added to the project  
if (CanAddATLClass(selProj, selObj))  
{  
   return true;  
}
