You know why. Because you are good at female body language but not good on written English body language.

Don't forget to add ON_WM_GETDLGCODE() to the message map of your class.

Just look what I do. The important line can work on a const method! I am following Scott Meyers recommendations!

CSomeClass& CSomeClass::operator=(const CSomeClass& source)
{
m_name=source.m_name;

LOGFONT lf;
(const\_cast(static\_cast (source.m\_font)).GetLogFont(&lf)); //this is the important line
m\_font.Detach();
m\_font.CreateFontIndirect(&lf);

//...

return \*this;

}
