Running command line silently with VbScript and getting output?

Question

I want to be able to run a program through command line and I want to start it with VbScript. I also want to get the output of the command line and assign it to a variable and I want all this to be done silently without cmd windows popping up. I have managed two things separately but not together. Here's what I got so far. Run the command from cmd and get output:

Dim WshShell, oExec
Set WshShell = WScript.CreateObject("WScript.Shell")
Set oExec = WshShell.Exec("C:snmpget -c public -v 2c 10.1.1.2 .1.3.6.1.4.1.6798.3.1.1.1.5.1")
x = oExec.StdOut.ReadLine
Wscript.Echo x

The above script works and does what I want except that cmd pops up for a brief moment.

Here's a script that will run silently but won't grab the output

Set WshShell = WScript.CreateObject("WScript.Shell")
Return = WshShell.Run("C:snmpset -c public -v 2c -t 0 10.1.1.2 .1.3.6.1.4.1.6798.3.1.1.1.7.1 i 1", 0, true)

Is there a way to get these two to work together?

Let me give you a background on why I want do to this. I am basically polling a unit every 5-10 minutes and I am going to get the script to email or throw a message box when a certain condition occurs but I don't want to see cmd line popping up all day long on my computer. Any suggestions? Thanks

You can redirect output to a file and then read the file:

return = WshShell.Run("cmd /c C:snmpset -c ... > c:empoutput.txt", 0, true)

Set fso  = CreateObject("Scripting.FileSystemObject")
Set file = fso.OpenTextFile("c:empoutput.txt", 1)
text = file.ReadAll
file.Close
