C2662 Error

[dushkin]

Hi,

This is a member function I wrote:
bool MyClass:perator==(const MyClass &a_suaDateTime) const
{
return (m_oleDateTime == a_suaDateTime.DateTime()); //m_oleDateTime
an MFC class
}

I get this error message:
error C2662: 'DateTime' : cannot convert 'this' pointer from 'const
class CSuaDateTime' to 'class CSuaDateTime &'
Conversion loses qualifiers

Why???
Thanks!

Why???

Apparently, 'DateTime' is a non-const function. Don't call it, just
compare the values of 'm_oleDateTime' members:

return m_oleDateTime == a_suaDateTime.m_oleDateTime;

Can't be sure of the definition of your class, but my guess is that

MyClass:ateTime() is not defined as a const method.

Hi Victor and Red!

You were both right! I forgot to set DateTime() as const method!

Thanks a lot!
