c++ error c3892 : You can not assign a const variable

Question

I have one error: You can not assign a const variable

Class :

    class RegChannel {
public:
    std::string channelID;
    std::string pwd;
    DWORD color;
    bool  bActive;

    bool operator < (const RegChannel &r) const {
        return(stricmp(channelID.c_str(), r.channelID.c_str()) < 0);
    }
};

std::set< RegChannel > regChannels;
std::map< std::string, DWORD > savedColor;
std::map< std::string, bool  > savedStatus;

Function:

        set< RegChannel >::iterator j;
    for( j = chatterUI->regChannels.begin(); j != chatterUI->regChannels.end(); j++ )
    {
       if( stricmp( (*j).channelID.c_str(), channelUI->channelID.c_str() ) == 0 )
        {
            (*j).color = channelUI->channelColor;
        }
    }

can you help me please ? (sorry for my bad english...)

You cannot modify the elements stored in a set. They are necessarily const. Instead, erase it and insert it again with the modification.

Did you search?

C++ STL set update is tedious: I can't change an element in place

what happens when you modify an element of an std::set?
