Editor to share with you an example analysis of the startup mode of VB.NET terminal services, I believe most people do not know much about it, so share this article for your reference. I hope you will gain a lot after reading this article. Let's learn about it together.

The Win32_TerminalService category provides terminal services load balancing indicators. The VB.NET Terminal Services startup mode code is as follows:

Imports System Imports System.Management Imports System.Windows.Forms Namespace WMISample Public Class CallWMIMethod Public Overloads Shared Function Main () As Integer Try Dim classInstance As New ManagementObject (_ "root\ CIMV2", _ "Win32_TerminalService", Nothing) 'Obtain [in] parameters for the method Dim inParams As ManagementBaseObject = _ classInstance.GetMethodParameters ("ChangeStartMode")' Add the input parameters. ' Execute the method and obtain the return values. Dim outParams As ManagementBaseObject = _ classInstance.InvokeMethod ("ChangeStartMode", inParams, Nothing) 'List outParams Console.WriteLine ("Out parameters:") Console.WriteLine ("ReturnValue: {0}", outParams ("ReturnValue")) Catch err As ManagementException MessageBox.Show ("An error occurred while trying to execute the WMI method:" & err.Message) End Try End Function End Class End Namespace

VB.NET Terminal Services startup mode comes with a parameter description:

The ChangeStartMode method changes the startup mode of the service. It will return one of the following integer values:

0-request has been accepted

1-request is not supported

2-the user does not have the necessary acc

3-the service cannot be terminated because other running services depend on it

4-the requested control code is invalid or the service does not accept it

5-the requested control code cannot be sent to the service because the service status (Win32_BaseService:State) is equal to 0, 1, or 2

6-Service has not been started

7-the service did not respond to the startup request in a timely manner

8-an unknown error occurred while starting the service

9-No directory path to executable service was found

10-the service is already running

11-the database responsible for adding new services is locked

12-A dependency on which the service depends has been removed from the system

13-the service cannot discover the required service from the dependent service

14-the service has been disabled by the system

15-the service does not have the correct authentication required to run on the system

16-removing the service from the system

17-the service has no thread of execution

18-there is a circular dependency when the service is started

19-there is a service with the same name running

20-there are invalid characters in the name of the service

21-invalid parameters passed for the service

22-the account running the service is either invalid or lacks permission to run the service

23-the service already exists in the service database available to the system

24-the service is currently suspended in the system
