[RESOLVED] Get System Hardware Info

I would have thought this was easy, but I can't find it. I need to find out what hardware the system has. For example CPU, ram, and harddrive. Is there any way to do this?

Thanks

Update:
Ok I found I can get most, maybe even all of my information using System.Management. My question now is how can I figure out what tables I can query. Table may be the wrong turm but since this is like an SQL query I'm not sure what to call it. But I can search using SELECT * FROM Win32_OperatingSystem. Anyone know where I can look to find all the available options for Win32_...
Thanks

Update:
Found it. The 101 examples has it.

mpdeglau could u post the code here?

What are you looking for?

I Have to develop One of Each of the next 3 Categories.

2. Get The Content Details of a Specific Directory or Sub-Directory (Folders)
3. See All Hidden Files in a Specific Directory.
4. Hide All Files from an Specific Extension in a Directory

Cat B (HardDisk):
1. Get The Free and Ocupied Space of a HD
2. See How Many EXE files have been eliminated from a HD in a Specific Period Of Time
3. See All Content of a HD by File Type
4. Determine How Many times a HD has been desfragmented

Cat C (Remote Conexion and Internet):
1. Remotly Check the existence of a Floppy Disk or a CD in a PC
2. Limit the File Types that can be downloaded from Internet
3. Limit the File Size that can be downloaded from Internet
4. Get the most visited WebSites by an User

If Someone Can help me in AT LEAST one i will really really appreciate it:)

Here is code to get the hard drive size and the free space. You need to add a reference to System.Management. You will have a much easier time if you download and install the vb.net 101 examples. There are a ton of classes you can use in the query. Install it to any folder you want then search that folder for WMI and it will show you the example project for this.

VB Code:

Imports System.Managment
 
Public Class Class1
  Private HDToGet as String   'the drive you want to get the size of
  Private _HDSize as string
  Private _HDFreeSpace
 
  Public Sub New()
 
  End Sub
  Public Sub New(specificHD as string)  'sets the drive to get the size
     HDToGet = SpecificHD
  End Sub
 
    Public Property HDSize() As String
        Get
            getHardDriveTotalSpace(CaptureDrive)
            Return _HDSize
        End Get
        Set(ByVal Value As String)
            _HDSize = Value
        End Set
    End Property
 
    Public Property HDFreeSpace() As String
        Get
            getHardDriveFreeSpace(CaptureDrive)
            Return _HDFreeSpace
        End Get
        Set(ByVal Value As String)
            _HDFreeSpace = Value
        End Set
    End Property
 
    Private Function getHardDriveTotalSpace(ByVal capDrive As String) As String
        Dim HDSize As String
 
        Dim objOS = New ManagementObjectSearcher("SELECT * FROM Win32_LogicalDisk")
        Dim objMgmt As ManagementObject
 
        For Each objMgmt In objOS.Get
            If objMgmt("Name").ToString = capDrive Then
                HDSize = objMgmt("Size").ToString
            End If
        Next
        _HardDriveSize = Format(HDSize / 1073741824, "0.00")
    End Function
 
    Private Function getHardDriveFreeSpace(ByVal capDrive As String) As String
        Dim HDSpace As String
 
        Dim objOS = New ManagementObjectSearcher("SELECT * FROM Win32_LogicalDisk")
        Dim objMgmt As ManagementObject
 
        For Each objMgmt In objOS.Get
            If objMgmt("Name").ToString = capDrive Then
                HDSpace = objMgmt("FreeSpace").ToString
            End If
        Next
        _HDFreeSpace = Format(HDSpace / 1073741824, "0.00")
    End Function
End Class

mpdeglau thx very much man
let me see now how that 101 examples work

Download Scriptomatic2 by the Microsoft team. It writes VBS as well as other languages to easily use WMI. It also emumerates all available options that you select from combo boxes.

i used your code and it was very very helpful, it just had a couple of errors therefore im going to post the corrected code (the error where in variables and meaningless stuffs like that)

VB Code:

Imports System.Management
 
Public Class Class1
    Private HDToGet As String   'the drive you want to get the size of
    Private _HDFreeSpace As String
    Private _HardDriveSize As String
 
    Public Sub New(ByVal specificHD As String) 'sets the drive to get the size
        HDToGet = specificHD
    End Sub
 
    Public Property HDSize() As String
        Get
            getHardDriveTotalSpace(HDToGet)
            Return _HardDriveSize
        End Get
        Set(ByVal Value As String)
            _HardDriveSize = Value
        End Set
    End Property
 
    Public Property HDFreeSpace() As String
        Get
            getHardDriveFreeSpace(HDToGet)
            Return _HDFreeSpace
        End Get
        Set(ByVal Value As String)
            _HDFreeSpace = Value
        End Set
    End Property
 
    Private Function getHardDriveTotalSpace(ByVal capDrive As String) As String
        Dim HDSize As String
 
        Dim objOS = New ManagementObjectSearcher("SELECT * FROM Win32_LogicalDisk")
        Dim objMgmt As ManagementObject
 
        For Each objMgmt In objOS.Get
            If objMgmt("Name").ToString = capDrive Then
                HDSize = objMgmt("Size").ToString
            End If
        Next
        _HardDriveSize = Format(HDSize / 1073741824, "0.00")
    End Function
 
    Private Function getHardDriveFreeSpace(ByVal capDrive As String) As String
        Dim HDSpace As String
 
        Dim objOS = New ManagementObjectSearcher("SELECT * FROM Win32_LogicalDisk")
        Dim objMgmt As ManagementObject
 
        For Each objMgmt In objOS.Get
            If objMgmt("Name").ToString = capDrive Then
                HDSpace = objMgmt("FreeSpace").ToString
            End If
        Next
        _HDFreeSpace = Format(HDSpace / 1073741824, "0.00")
    End Function
End Class
