Listing/Modifying Server Information with Visual Basic.NET and VBScript Using WMI - How to change your computer name using WMI
(Page 5 of 5 )
You can change your computer name using VB.NET and WMI as shown in the following:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e
As System.EventArgs) Handles Button1.Click
Try
Dim classInstance As New ManagementObject( _
"root\CIMV2", _
"Win32_ComputerSystem.Name='SERVER'", _
Nothing)
Dim inParams As ManagementBaseObject = _
classInstance.GetMethodParameters("Rename")
inParams("Name") = "server2" 'rename to
inParams("Password") = "admin"
inParams("UserName") = "administrator"
Dim outParams As ManagementBaseObject = _
classInstance.InvokeMethod("Rename", inParams,
Nothing)
MessageBox.Show("ReturnValue: {0}", outParams
("ReturnValue"))
Catch err As ManagementException
MessageBox.Show("Error: " & err.Message)
End Try
End Sub
Note that I am using “InvokeMethod” to execute a WMI method (in this case “Rename”) dynamically. “inParams” (an object of ManagementBaseObject) is specifically used to pass parameters to the WMI method “Rename”. It mainly contains the required information to penetrate through the authentication and authorization (username and password) of security, along with the new computer name. We can get the result after executing the WMI method “Rename” into “outParams”.
You can achieve the same result using the following VBScript code:
strComputer = "."
Set objWMIService = GetObject("winmgmts:\\" & strComputer & "\root\CIMV2")
Set objShare = objWMIService.Get("Win32_ComputerSystem.Name='SERVER'")
Set objInParam = objShare.Methods_("Rename").inParameters.SpawnInstance_()
objInParam.Properties_.Item("Name") = "server2"
objInParam.Properties_.Item("Password") = "admin"
objInParam.Properties_.Item("UserName") = "administrator"
Set objOutParams = objWMIService.ExecMethod("Win32_ComputerSystem.Name='SERVER'", "Rename", objInParam)
Wscript.echo "ReturnValue: " & objOutParams.ReturnValue
Summary
You can further delve into the classes of WMI and design your own application to manage almost every important aspect of the Windows OS. If you extend your skills to ASP.NET, then you can develop a web application which can manage your server information on the fly, without your presence in the office itself! I think you can imagine the same, if you further extend it to the Pocket PC level! Good luck.
Anyway, once again, I must be thankful to all the readers who appreciated and encouraged me to further expand the series in a much more useful and efficient manner. Thank you very much.
