The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

WMI call not executing in VB.Net

Asked by iptrader in Microsoft Development, Microsoft Visual Basic.Net, .Net Editors & IDEs

Tags: wmi, from, win32_computersystem

I am building a small application that retrieves system information via WMI.  My VBScript works fine, however, the VB.Net code does not execute.  Further, I get an "Unspecified Error" when I try to trap the error to find out what it is.  Below is the troublesome code:

**********************

 Function getinfo()
        On Error GoTo Errhand
        Dim objWMIService As Object
        Dim colItems As Object
        Dim objItem As Object
        Dim strComputer As String = txtServerName.Text

        objWMIService = GetObject("winmgmts:\\" & strComputer & "\root\cimv2")
        colItems = objWMIService.ExecQuery("Select * from Win32_ComputerSystem", , 48)
        For Each objItem In colItems
            MsgBox("Name: " & objItem.Name)
        Next

Errhand:
        MsgBox(Err.Number & " " & Err.Description)
    End Function

**********************

I am referencing System.Management with Imports System.Management.  

Can someone give me a bit of assistance with this?

Thanks,

IPT
