Status: offline 		i have a rather large problem,  the small part that I would like help with here is assigning a value to a variable.  the problem is that the value will be a responce to a command I send to a device, using telnet. 

send message --> ((one line responce)) --> variable.



so far I have and it works great. Thanks to this site.



Option Explicit
Dim objShell
Set objShell = CreateObject("WScript.Shell")
objShell.run "C:\WINDOWS\system32\telnet.exe"
wscript.sleep 500
objshell.sendkeys "open 10.1.0.2"
wscript.sleep 500
objshell.sendkeys "{enter}"
wscript.sleep 500
objshell.sendkeys "some command here {enter}"

'******************************************
'wait for return of text
'assign text to variable
'******************************************

Set objShell = Nothing
WScript.Quit 0

I also have another question if this one gets fixed. :)               




this site is great!!! i have spent the last two day wondering through and have learned more here then I have in a long time.  Thanks!!!!

while stumbling around this site i cam apon some helpful links regarding the .exec syntax.  If I understand them fully, .exec is good for a single command that would be typed at a "run" promt("windows key" + R). how ever, the system I am inquireing about requires a login and several other commands to get to the point where I send a single command and get back useful data.  sendkeys will get me to the screen and the I can see the data on the cmd window if I send the (for lack of a better term) data query command.  Thats all well and good but that still doesn't put that value into a usable variable that I can pass.

also I must say, i am very impressed with the level of assistance and information avalable on this site.  keep up the good work.

Status: offline 		This is definitely not where VBScript shines. You can use VBScript to run  telnet session. It is not particularly robust however and it can get really flaky. You could look at AutoIt which might be a little more robust. If this were my task to do however, I would use powershell. Here is a powershell example:
