Hello! The task of making analogue AIDA or Speccy , but more simplified. I do on C # , Windows Forms using Environment , the register and DriveInfo .

There were difficulties with the withdrawal of information about the mouse and keyboard. I want to display in the TextBox at least that they are connected, but I have no idea where to look for it. There were thoughts that there is a name in the registry that stores some value of 1 or 0, that they are connected.

The question is: Where to look for information that a mouse and keyboard are connected to the PC.

The program is in working condition (draft)

PS The application should work on different PCs or laptops running Win7 and higher

    In the project's References, set the link to System.Management . In the class where you will work, list using System.Management; Console program example:

      static void Main(string[] args) { Console.WriteLine(HasDevice("PointingDevice")); Console.WriteLine(HasDevice("Keyboard")); Console.ReadKey(); } private static bool HasDevice(string typeDevice) { var mObjects = new ManagementObjectSearcher(@"root\cimv2", "SELECT * FROM Win32_" + typeDevice); //выводим разнообразную информацию об устройствах var devices = (from ManagementObject d in mObjects.Get() as ManagementObjectCollection select d); foreach (var item in devices) { foreach (var p in item.Properties) { Console.WriteLine($"{p.Name}==>{p.Value}"); } } //определяем подключено ли устройство var result = (from ManagementObject d in mObjects.Get() as ManagementObjectCollection where d.Properties["Status"].Value.ToString() == "OK" select d).First(); //выводим результат return result != null; }
    • Okay I will try. Thank you - Alexander
