The standard string class (defined in ''string'', ''string.h'' is the C string functions) lives in the std namespace. You can write ''std::string'' when you want a string, or add ''using std::string'' at the top of the file and just use ''string'' without the std:: when you need it.

It seems to me that a CString will solve all your problems. It is variable length, and you can use "normal" operators on it. If you are using MSCV++ just look up CString in the help and under one of the related links it tells you what file to include.
After that code, myStr would hold "Hello World", and you never had to do anything related to telling it how much memory you need

You are not a real programmer until you end all your sentences with semicolons;
CString myStr;myStr += "Hello";myStr += '' ''; // I am not quite sure this will work... I think it willmyStr += "World"; After that code, myStr would hold "Hello World", and you never had to do anything related to telling it how much memory you need

I tried the CString but afx.h is giving me linking errors.
std::string for some reason is failing to get the message across in DirectPlay.
The server''s log file correctly shows the type, size, from and to but the message is empty.
I''m assumming I have to convert the message to a char * and send that accross and then convert back to read it.
DirectPlay has no problem getting char* sent.
