    VC++ Sending data from a structure in one class to a ListBox in a second class.

    Hello everyone, I'm building a simple RPG type game and have run into a snag with my inventory. The program is a Dialog based application, the problem I've run into is I've created a seperate class to contain all my item handling code and a listbox on the main dialog to display the names of the items. I'm trying to set the items in the listbox by using:

    and the function code is:

    void CItems::PopulateShop(CString* holder)
    	*holder = ShopList.m_sName;		

    The error I receive is:
    error C2664: 'PopulateShop' : cannot convert parameter 1 from 'const char' to 'class CString *'
    Conversion from integral type to pointer type requires reinterpret_cast, C-style cast or function-style cast

    In that particular case I tried to use pointers in order to get the data, I am not very good with pointers yet and likely did not use them properly. Am I heading in the right direction with the pointers? Or should I be attempting to do this in a completely different way?

    Study this and read tutorial
    #include <iostream>
    #include <string>
    using namespace std;
    void set_string(string &ref_string)
        ref_string = "setting reference parameter";
    void set_string(string *ptr_string)
        *ptr_string = "setting pointer parameter";
    int main()
        string s1, s2;
        cout << "s1 = " << s1 << endl;
        cout << "s2 = " << s2 << endl;
        return 1;
