S[i] means the i'th character in the string S. The for loop is sending a
seaprate message for each character in the nickname, followed by sending a
zero to terminate the string.

The msgValue is not a string, it is an integer constant. You have to look
up what the value of WM_USER is. My documentation says it is 0x400, or 1024
in decimal. You then add 20 or 21 to this and pass this integer as
msgValue.
