scanning ip address and ports

[deoblo1]

can i just use the winsock control and tell it to scan the ports or something like that, and would i just use something like the data arive operation and look at the data? But my problem is what if i did that, and I used winsock to look at port 80, and would microsoft internet explorer still get the information comeing in on port 80? or would i intercept it?

something like this should work:
[code]
dim i as integer
for i = 0 to 6000 ' or however many ports there are
winsock1.localport = winsock1.localport + 1
'scan ports here
Next i

[deoblo1]

so if i put like a recive data, function ect...it wont change anything? like any of the data? if i just look at it? How would I just look at it?

Where SteveCRM says "'scan ports here" use winsock and attempt to send some kind of data to that port...and if that data is received with no errors then that port exists/open/used on that ip. I think it's basicly like pinging the ip on misc ports...just sending random packets.
