Code on Client winsock arrival which call for screenshot command and send file back to server when done taking screenshot

May problem is that for example filesize is 224kb... the server only received up to 222kb it always lack of 2kb. File is incomplete so I can't display the picture that I taken from he client.

by the way this not my code I just download it from pscode and modify it to suit my needs. tnx to Ronny R. Germany Berlin
