Get the Keyboard Details of Your System in Windows Form

Introduction

This article explains how to get the details of the Keyboard connected to your system. Here I will get the information from the Win32_Keyboard class.

What Win32_Keyboard is

The Win32_Keyboard WMI class a represents keyboard installed on a computer system running Windows.

Design

Create a new Windows Forms Application Project.

Add one button control to the form.

Design your screen as in the following screen:

Next add a reference for "System.Management".

To add the reference use the following procedure.

Go to Solution Explorer, select the project and right-click on that and choose "Add Reference" from the menu.

A window will open; in that choose the ".Net" tab.

It will show a list. In that list, choose "System.Management" and click the "OK" Button.

Now go to code view.

Add the namespace "using System.Management;".

Write the following code in the Button Click event:

private void button1_Click(object sender, EventArgs e)
{
SelectQuery Sq = new SelectQuery("Win32_Keyboard");
ManagementObjectSearcher objOSDetails = new ManagementObjectSearcher(Sq);
ManagementObjectCollection osDetailsCollection = objOSDetails.Get();
StringBuilder sb = new StringBuilder();
foreach (ManagementObject mo in osDetailsCollection)
{
sb.AppendLine(string.Format("Caption: {0}", (string)mo["Caption"]));
sb.AppendLine(string.Format("ConfigManagerErrorCode: {0}", mo["ConfigManagerErrorCode"].ToString()));
sb.AppendLine(string.Format("InstallDate: {0}", Convert.ToDateTime(mo["InstallDate"]).ToString()));
sb.AppendLine(string.Format("ConfigManagerUserConfig: {0}", mo["ConfigManagerUserConfig"].ToString()));
sb.AppendLine(string.Format("CreationClassName : {0}", (string)mo["CreationClassName"]));
sb.AppendLine(string.Format("Description: {0}", (string)mo["Description"]));
sb.AppendLine(string.Format("DeviceID : {0}", (string)mo["DeviceID"]));
sb.AppendLine(string.Format("ErrorCleared: {0}", (string)mo["ErrorCleared"]));
sb.AppendLine(string.Format("ErrorDescription : {0}", (string)mo["ErrorDescription"]));
sb.AppendLine(string.Format("Layout: {0}", (string)mo["Layout"]));
sb.AppendLine(string.Format("NumberOfFunctionKeys : {0}", (ushort)mo["NumberOfFunctionKeys"]));
sb.AppendLine(string.Format("LastErrorCode : {0}", (string)mo["LastErrorCode"]));
sb.AppendLine(string.Format("Name : {0}", (string)mo["Name"]));
sb.AppendLine(string.Format("PNPDeviceID: {0}", (string)mo["PNPDeviceID"]));
sb.AppendLine(string.Format("PowerManagementSupported : {0}", mo["PowerManagementSupported"]).ToString());
sb.AppendLine(string.Format("Status : {0}", (string)mo["Status"]));
sb.AppendLine(string.Format("SystemCreationClassName : {0}", (string)mo["SystemCreationClassName"]));
sb.AppendLine(string.Format("SystemName: {0}", (string)mo["SystemName"]));
}
MessageBox.Show(sb.ToString());
}

In the code above I am getting the information from Win32_Keyboard and showing it in a Message Box on a button click.

SelectQuery

It represents a WQL (WMI Query Language) SELECT data query.

ManagementObjectSearcher

It retrieves a collection of management objects based on a specified query.

This class is one of the more commonly used entry points to retrieving management information.

ManagementObjectCollection

It represents various collections of management objects retrieved using WMI.

Now build your application. Click on the button; it will show the Keyboard details in a Message box.

Thank you.
