Guys i'm facing a problem with this code, the problem is the timeout by timeout i mean the

time it takes the program to tell me if the server is connected or not. If i use my

localhost i get the answer fast, but when i connect to outside my localhost it takes 50sc -

1.5 min to response and the program frezz until it done. HOw can i fix the frezzing, or make

my own timeout, like if still waiting after 50sc, tell me connection failed and stop?

please use codes as help, becouse i would understand it better, thanks for any help i get
