Make three colums in the listbox and populate them.

How do I create a list box with three columns ant populate all three colums at once???  I am using MS c++ .Net 2003
I tried creating a Clistbox and using a Cstring format to populate it but the text in each column is not alined right.
I used:
           CString txt;
           int value1, value2;

           txt.Format(%9s    %6ds    %7d ", txt1, value1,value2);
           clist.AddString(txt);

Sample output:

         J23.1            234         123
       J12.0               129          349
          J4                23          90
