Ping (For waty)
The code you sent for ping.bas didn't seem to work on my computer. No errors generated, just returns 0's
I run win 95 4.00.95 VB5 pro... weird...
thanks alot
jon

Do you ping using a computer name or an IP adress?
ASKER
Yes I pinged several IPs including the loopback IP (127.0.0.1)
the one you mentioned in the code........
they all respond 0's... even the address
the one you mentioned in the code........
they all respond 0's... even the address
Does your isp support Ping? Some ISP doesn't
Try it under dos
Try it under dos
ASKER
DOS ... there is a ping.exe but would that work if the network is win95 all the way??
ASKER
I've tried a few widows95 ping programs without problems....
thanx
Jon
thanx
Jon
Here is again the code, I have tried it hre, and works very well. NB : I am under NT

WATY, I found some very similar code that works ....
Can u tell me the difference ?

I think it should be quite the same. I will take a deeper look.
Maybe there is a big in my code under certains circumstances.

You still there waty??
Yes, did you receive my last mail?
