[VBSCRIPT ]check if TCP port is open

[eccofresh]

Hi,

I have a problem: I have a script that needs to check if a tcp port is used. if its not used it shall start a program, if the port is used it should do nothing.

The tcp port I want to check is 5555.

I read something about winsock but didnt really get anywhere :s.

I could do it by using the netstat ?command and put the output in a file but thats taking to long as it needs to be done under 300ms (milisecounds).

thx in advance!

I don't believe plain-old VBscript is capable of network I/O by itself... perhaps you meant VB?

One question though: is the TCP port you are checking local or remote? If it's local, you can simply use Winsock and try to bind to that port--if you can't bind to it, then the port is in use.

Hi zeta,

I do mean vbscript, not VB.

Yes, the port is local

AFAIk, it's not possible in plain-old vanilla VBscript... which I stated earlier.

Hi,

I got it working using w3sockets from http://www.dimac.net/

afaik it is possible to do it using winsock, but you need a developer license, even though I have vb6 and vs.net installed I cant use it though :s doesnt matter now anyways... thx
