wow. Thanks man. This explanation really helps my understanding in C character pointers. I will try this testing code later. Thanks a lot.

hello mark Thanks for the reply. I just add the byte order method htons and it works. Thanks for the solution. I really2 appreciated it. Also thanks for the tips to take error messages seriously. I will take your advice. I know error messages is important for debugging, but i just consider a simple connection from client/server, thats why i dont want to concern the error messages. I will be careful next time. Thanks again.

Thanks guys for your help and comments. Really appreciate it.

Thanks Pallini. I think that should solve it. I altered the code and there are no more error. I didnt update the code on the receiver (server) side yet but i think it should not be a problem. If there are problems, i will get back to you guys again. Thanks alot guys.
