Trouble compiling a member variable using a CList template with VS Community 2012

Question

//Class ParmContainer has a constructor that takes 3 CString argments with the third argument optional

class ParmContainer
{
public:
	ParmContainer(CString label, CString type, CString format = CString("") );
}

//Here is the constructor
ParmContainer::ParmContainer(CString label, CString type, CString format)
{
	Create(label, type, format);
}

//Class AddParms has a variable m_Parms declared as a template for a CList object passing in the class ParmContainer as the type
class AddParms
{
...
public:
	CList<ParmContainer,ParmContainer&> m_Parms;	
}

//Function Create() calls m_Parms.AddHead(ParmContainer(name, type)); which produces errors
bool AddParms::Create(CString name, CString type)
{
...
	m_Parms.AddHead(ParmContainer(name, type));
	
	return (true);
}

This code compiled OK on .NET 2003.  I am using Visual Studio Community 2022 and .NET 4.8 and all the following errors are produced:

AddParms.cpp(50,9): error C2665: 'CList<ParmContainer,ParmContainer &>::AddHead': no overloaded function could convert all the argument types

Answer 1

Declare your CList like this.

CList<ParmContainer, const ParmContainer&> m_Parms;
