When using mapvariable[somekey] = somevalue to insert into a map variable, how to check whether there is conflicting key value in the map in an elegant way?
You can use map::find() to check whether the key is already present in map. Well, the  operator will overwrite the existing entry if the key already exists.
OT: Be a little careful while using  operator with map, especially while reading from map. For instance, if you try to get a key-value which is not in map, it create a new entry and return the default value. For instance,
// An empty map.
// If you lookup a for a key which is not present,// it will create empty entry and return. It won't// throw any error.
CString LookupKey = _T("key"); // Key which is not present.
CString Value = TempMap[LookupKey];
Good to know that. Previously I wrongly think we can check whether the expression mapvariable[somekey] returns null or not to check whether the element exists. Now I think I am wrong, and using find is the optimum solution to check existence, and using  could never tell us whether we insert new pair or overwriting an old pair, all are correct understanding?
I am attempting to access the file names as they get displayed in the listview of the Common File Dialog and change the file name text in certain ways. I was able to do this when the listview was not of style Ownerdata (which seems to be in XP), but in Vista they seem to be of style Ownerdata and I am not able to do a SetItemText anymore. Has anyone done something like this, and can help?
Yes, you are right. Thats my problem. I have a similar function that shows all the bands in a list.
I'm able to show all the musics from a band... I use: band->show_availavle__music() This gives me the music from that specific band.
But I want an option to show all the musics from all the bands. I mean, all the objects( music) from all the correspondent objects (band).
I'm not sure i understand that.. Can you give me an example?
This is the code I have to display the music from ONE specific Band:
cout<<"Whats the name of the band you want to search music from? ";
band = myManager.select_band_name(name);
cout << "List of " << name <<"'s music.\n" << endl;
for ( it=available_music_list.begin() ; it != available_music_list.end(); it++ )
cout << *it << endl;
But what of the function you mentioned that "shows all the bands in a list?" Much like select_band_name() returns a single Band object, you need a function that returns a Band object based on an index or an iterator. That way you could use it in a loop.

I have a lab assignment in my C++ class that asks me to do the following:
-Create an application that prompts the user for two 3-digit numbers, then display the result in the following format:
The problem I am having is the method I'm trying to use. I am using the carry over technique, and I need a way to split up the 3-digit numbers into single numbers, then multiply/carry/add accordingly
