Hi Atlast, figured it out. Displaying the values is fine with properties of the
management object. But for setting i need to use the InvokeMethod function. Funny!!!
The articles were of a GREAT help. The C# code is as below spark : one question
for u at the end of the post using System;
using System.Management;
using System.ServiceProcess;
using System.Reflection;
namespace CSharp
{
/// <summary>
/// Summary description for Class1.
/// </summary>
class Class1
{
/// <summary>
/// The main entry point for the application.
/// </summary>
[STAThread]
static void Main(string[] args)
{
Class1 x=new Class1();
Console.WriteLine("Name of Service and StartMode before Changing...");
x.DisplayData();
Console.WriteLine("Changing StartMode ...");
x.ChangeData();
Console.WriteLine("Name of Service and StartMode after Changing...");
x.DisplayData();
Console.ReadLine();
}
void DisplayData()
{
//
// TODO: Add code to start application here
//
ManagementClass mc = new ManagementClass("Win32_Service");
ManagementObjectCollection moc = mc.GetInstances();
foreach(ManagementObject mo in moc)
{
try
{
if (mo.Properties["Name"].Value.ToString()=="WINS")
{
Console.WriteLine(mo.Properties["Name"].Value.ToString() + ":" +
mo.Properties["StartMode"].Value.ToString());
}
}
catch(Exception p_objException)
{
Console.WriteLine(p_objException.Message);
}
}
} void ChangeData()
{
//
// TODO: Add code to start application here
//
ManagementClass mc = new ManagementClass("Win32_Service");
ManagementObjectCollection moc = mc.GetInstances();
foreach(ManagementObject mo in moc)
{
try
{
if (mo.Properties["Name"].Value.ToString()=="WINS")
{
//The following lines DONT work???????
mo.Properties["StartMode"].Value="Manual";
mo.SetPropertyValue("StartMode","Manual");
//The above lines DONT work??????? //The following lines WORK!!!!!!
Object[] o1=new object[1];
o1[0]="Automatic"; // Set the startmode as "Automatic"(Not "Auto" though the WMI
Classes print it as "Auto") or "Manual" or "Disabled"
mo.InvokeMethod("ChangeStartMode",o1);
//The above lines WORK!!!!!!
}
}
catch(Exception p_objException)
{
Console.WriteLine(p_objException.Message);
}
}
}
}
}
spark : though the invokeMethod works and the job gets done, an academic
question. why doesnt the changes get reflected when i just change the properties. my
guess is that it is disconnected(!!!!!!). if so then, how do i save it back to the
management object??? hth regards, sr
