Thread: Internet speed tester

Do it the well tested and smart way...

In code... ping times do not tell you transfer speeds.
To know that you have to actually send and receive data with a known server and time it.

Far and away the best plan is to just "let 'er rip"... and plan your software to not time out on slower speeds.

You will need timer resolution in milliseconds... on Windows you can do that with the SetTimer Function (Windows). If you are not using GIU mode you will need to setup a timer call back function... Or you can use the GetTickCount Function (Windows); call it once at the beginning, call again at the end and subtract.

You will then need to connect to a high bandwidth server and download a test file of several megabytes, usually by FTP... time the download, check the size, then do the math... X bytes in Y milliseconds = Speed. ( FTP Sessions (Windows) )

Of course you'll need to clean up your mess after... delete the file, kill any timers etc, before you exit.

Your best bet is to sit down and plan your code before starting to write. Look up all the functions, experiment with them as needed... then you can begin final code development. If you get stuck you can post the relevent code sections and we'll see what we can do...

OR... you could just take the easy way out and ask your end user to enter the speed as a setting.
