Dear Friends,

I would like to know how to find USB Modems through query.

I have written the WMIquery:

C#

var usbdrives = new ManagementObjectSearcher("SELECT DeviceID FROM Win32_DiskDrive WHERE InterfaceType='USB'");

This is working for USB PenDrives, but I need to find the modems.

How to write WMI query for USB Modems?
If any information regarding this please share with me.

Regards,

AnilKumar.D

WMI will contain all the information you need in the Win32_POTSModem class. In C# or .Net, you can utilize the System.Management namespace to query WMI.

Within .Net, you can use MgmtclassGen.EXE from the platform SDK to generate a class object representing the WMI class.

The command line would be like this:

C:\Program Files\Microsoft SDKs\Windows\v6.0A\Bin\mgmtclassgen.exe Win32_POTSModem /L CS /P c:\POTSModem\Win32_POTSModem.cs

and then you can use that in your code:

C#

using System;
using System.Collections.Generic;
using System.Management;
using ROOT.CIMV2.Win32;

public class MyClass
{
  public static void Main()
  {
    foreach (POTSModem modem in POTSModem.GetInstances()) {
      Console.WriteLine(modem.Description);
    }
  }
}

But it will get all modem names.But i want one the Modem which i inserted

NaveedAhmed 1-Dec-12 8:04am

you can get available ports by using.. the following code:

// Get a list of serial port names.
string[] ports = SerialPort.GetPortNames();

foreach (string port in ports)
{
listBox1.Items.Add(port);
}

C#

string modems = "";
           
                ManagementObjectSearcher searcher = new ManagementObjectSearcher("root\\CIMV2", "SELECT * FROM Win32_POTSModem ");

                foreach (ManagementObject queryObj in searcher.Get())
                {
                    if ((string)queryObj["Status"] == "OK")
                    {
                        
                        listBox1.Items.Add(queryObj["AttachedTo"] + " - " + System.Convert.ToString(queryObj["Description"]));
                    }
                }
             
            
            return modems;

try...this to get port

C#

using System;
using System.Management;
using System.Windows.Forms;

namespace WMISample
{
    public class MyWMIQuery
    {
        public static void Main()
        {
            try
            {
                ManagementObjectSearcher searcher =
                    new ManagementObjectSearcher("root\\CIMV2",
                    "SELECT * FROM Win32_POTSModem WHERE AttachedTo = 'COM7'");

                foreach (ManagementObject queryObj in searcher.Get())
                {
                    Console.WriteLine("-----------------------------------");
                    Console.WriteLine("Win32_POTSModem instance");
                    Console.WriteLine("-----------------------------------");
                    Console.WriteLine("AttachedTo: {0}", queryObj["AttachedTo"]);
                }
            }
            catch (ManagementException e)
            {
                MessageBox.Show("An error occurred while querying for WMI data: " + e.Message);
            }
        }
    }
}
