I really do not have a clue how VBScript works and I have this program that does something similar to what I want to do and I'm sure if I could understand the code I could use bits and pieces, I am on the tightest deadline and do not have time to try to figure out VBScript so I would be eternally grateful if someone could convert it to either VB.net 2003 or C/C++

The following is the VBScript code to list all the programs installed on a PC:

Option Explicit

Dim sTitle
sTitle = "InstalledPrograms.vbs by Bill James"
Dim StrComputer
strComputer = InputBox("Enter I.P. or name of computer to check for " & _
                      "installed software (leave blank to check " & _
                      "local system)." & vbcrlf & vbcrlf & "Remote " & _
                      "checking only from NT type OS to NT type OS " & _
                      "with same Admin level UID & PW", sTitle)
If IsEmpty(strComputer) Then WScript.Quit
strComputer = Trim(strComputer)
If strComputer = "" Then strComputer = "."

'Wscript.Echo GetAddRemove(strComputer)

Dim sCompName : sCompName = GetProbedID(StrComputer)

Dim sFileName
sFileName = sCompName & "_" & GetDTFileName() & "_Software.txt"

Dim s : s = GetAddRemove(strComputer)

If WriteFile(s, sFileName) Then
 'optional prompt for display
 If MsgBox("Finished processing.  Results saved to " & sFileName & _
           vbcrlf & vbcrlf & "Do you want to view the results now?", _
           4 + 32, sTitle) = 6 Then
   WScript.CreateObject("WScript.Shell").Run sFileName, 9
