There is no specific automatic method for this purpose in CString, but u can use your brain.
the len method of CString  returns the length of CString. you will do:

int groups=s1.len() /3;
CString s2;

now as you know the length of string

for(int c=len; c>3; c-=3)
{
//take the substring from s1 and put in s2 and then put the comma in s2.
//the length of s2 will be = s1.len() + groups;
}

Got?

Regards

One thing i forgot to tell that you can use the same string and use the 'insert' function to insert the commas in string but you will have to determine the number of groups of strings to be made in source string.
