Common methods of the CString class----left (), Mid (), right ().

CString Left ( int ncount )                   const; Get the first ncount characters starting from the left 1

CString Mid ( int nfirst )                      const; start with the ncount+1 character on the left, and get all the following characters

CString Mid ( int nfirst, int ncount )    const; start with the nfirst+1 character on the left and get the ncount characters later

CString Right ( int ncount )                  const; Get right-to-left front ncount characters starting from the right 1

Note:

Adding a const to the back of a function means:

If a class declares a constant object, the object can only use the method behind the const.

Cases:

CString A, B;
A = "123456789";

b = A.left (4); Value is: 1234
b = A.mid (3); Value is: 456789
b = A.mid (2, 4); Value is: 3456
b = A.right (4); Value is: 6789
