C # prepared by the CD-ROM to do startup disk full description of: thinkersky (Email: yanghuangming@rongji.com) a: 1 programming ideas, create a boot disk boot disk, insert to create the program automatically detecting the drive to CD using WMI (Windows Management Architecture: Windows Management Instrumentation) Reads the serial number (with uniqueness) of the disc and write the serial number to the registry. 2 2: Related knowledge 1, what is WMI? WMI (Windows Management Architecture: Windows Management Instrument is the implementation of Microsoft Web-based Enterprise Management (WBEM) and Desktop Management Task Force (DMTF) industry standards. It is a standard-based development interface, which is used Control the management computer. It provides a simple way to manage and control system resources. If you want to know him, you can refer to Micorosft Platform SDK. In this case, we only achieve a simple feature, get our system CD Related information. [We need to implement classes provided under System.Management namespace.]. 2, how to operate the registry in the C # Operation of language operation registry in the registry, which is more simple and convenient to operate the registry in the C #.
The following example provides a method for operating the registry in the C #: use Microsoft.win32; useing system.diagnostry; private void access_registry () {// Create a new button under HKEY_LOCAL_MACHINE / SOFTWARE, Named CDDRIVESN RegistryKey Key = Registry.localmachine.opensubKey ("Software", true); // Add a sub-key registryKey newkey = key.createSubkey ("cddrivesn"); // Setting the value of this subkey newkey.setValue ("cddrivesn", "123456789" ); // Get data from the registry // to find your cpu registryKey pregkey = registry = pregalmachine; pregkey = pregKey.opkey ("hardware // description // system // centralprocessor // 0"); Object val = pRegKey.GetValue ( "VendorIdentifier"); Debug.WriteLine ( "The central processor of this machine is:" val); // delete the key RegistryKey delKey = Registry.LocalMachine.OpenSubKey ( "Software", true); Delkey.DeleteSubKey ("cddrivesn");} III, write code as follows 1, create a startup disk using system; useing system.drawing; useing system.collections; using system.componentmodel; using System.windows.Forms; use system.data; using system.diagnostics; using microsoft.win32; namespace at_regcdrom {/// //// Form1 summary description. /// public class form1: system.windows.Forms.form {///// The required designer variable. /// private System.ComponentModel.Container components = null; private System.Windows.Forms.Label label1; private System.Windows.Forms.Button button1; private static string cdRomSn; public Form1 () {// // Windows Forms Designer supports // initializeComponent (); // // Todo: Add any constructor code //} //// / / / / / / / / / / / / / / / / / / / / / / / / / / / /.

ContentAlignment.middleCenter; /// Button1 // this.button1.location = new system.drawing.point (104, 56); this.button1.name = "button1"; this.button1.size = new system.drawing.

";" THIS.BUTTON1.TEXT = "Close";}} else {// Initializes the variables to pass to the messagebox.show method. String message = "Please insert the startup CD to register!"; String C aption = "CD Registration"; MessageBoxButtons buttons = MessageBoxButtons.OKCancel; DialogResult result; // Displays the MessageBox result = MessageBox.Show (this, message, caption, buttons, MessageBoxIcon.Warning, MessageBoxDefaultButton.Button1);. if (result = = DialogResult.ok) {readcdrom ();} else {Application.exit ();}} DRIVECLASS.DISPOSE ();} /// /// The information is written to the registry.
