I HATE WMI

Posted by & filed under Programming, WMI.

Trying to retrieve the wireless stats:

VB.Net Class:
Public Class clsWMI
Private objOS As ManagementObjectSearcher
Private objCS As ManagementObjectSearcher
Private objMgmt As ManagementObject
Private m_strComputerName As String
Private m_strManufacturer As String
Private m_StrModel As String
Private m_strOSName As String
Private m_strOSVersion As String
Private m_strSystemType As String
Private m_strTPM As String
Private m_strWindowsDir As String

Public Sub New()

objOS = New ManagementObjectSearcher("SELECT * FROM Win32_OperatingSystem")
objCS = New ManagementObjectSearcher("SELECT * FROM Win32_ComputerSystem")
For Each objMgmt In objOS.Get

m_strOSName = objMgmt("name").ToString()
m_strOSVersion = objMgmt("version").ToString()
m_strComputerName = objMgmt("csname").ToString()
m_strWindowsDir = objMgmt("windowsdirectory").ToString()
Next

For Each objMgmt In objCS.Get
m_strManufacturer = objMgmt("manufacturer").ToString()
m_StrModel = objMgmt("model").ToString()
m_strSystemType = objMgmt("systemtype").ToString
m_strTPM = objMgmt("totalphysicalmemory").ToString()
Next
End Sub

Public ReadOnly Property ComputerName()
Get
ComputerName = m_strComputerName
End Get

End Property
Public ReadOnly Property Manufacturer()
Get
Manufacturer = m_strManufacturer
End Get

End Property
Public ReadOnly Property Model()
Get
Model = m_StrModel
End Get

End Property
Public ReadOnly Property OsName()
Get
OsName = m_strOSName
End Get

End Property

Public ReadOnly Property OSVersion()
Get
OSVersion = m_strOSVersion
End Get

End Property
Public ReadOnly Property SystemType()
Get
SystemType = m_strSystemType
End Get

End Property
Public ReadOnly Property TotalPhysicalMemory()
Get
TotalPhysicalMemory = m_strTPM
End Get

End Property

Public ReadOnly Property WindowsDirectory()
Get
WindowsDirectory = m_strWindowsDir
End Get

End Property

End Class

And a way to invoke it:

Dim objWMI As New clsWMI()
With objWMI
Debug.WriteLine("Computer Name = " & .ComputerName)
Debug.WriteLine("Computer Manufacturer = " & .Manufacturer)
Debug.WriteLine("Computer Model = " & .Model)
Debug.WriteLine("OS Name = " & .OsName)
Debug.WriteLine("OS Version = " & .OSVersion)
Debug.WriteLine("System Type = " & .SystemType)
Debug.WriteLine("Total Physical Memory = " & .TotalPhysicalMemory)
Debug.WriteLine("Windows Directory = " & .WindowsDirectory)
End With
