Hello, So you mean to create an hotkey ???
If you want to press Ctrl + R, and your program is minizimed, so Ctrl+R is an hotkey for your program.
------------------------------------
To begin, create a new solution (Windows Application).
I call the solution " HotkeyNameSpace " .
[Do not change your form name After creating the solution.]
[And Save your solution before starting].
------------------------------------------------------------
After you create the solution: go to " Solution Explorer ", and add to your PROJECT (NOT SOLUTION) a new item (Make the new item: A CODE FILE), and make the CODE FILE's name " Hotkey.cs ".
And add another code-file to your project,make its name " SystemHotkey.cs ".
--------------------------------------------------------------------------------------------------------------------
Now [From the Solution Explorer] open Hotkey.cs, After you open it: you see an empty page [empty page code].
And copy this code to the empty page (Hotkey.cs page):
then Save your project.Code:using System; using System.Runtime.InteropServices; using System.Windows.Forms; namespace Hotkey.Win32 { /// <summary> /// Summary description for Win32. /// </summary> public class User32 { [DllImport("user32.dll")] public static extern bool RegisterHotKey(IntPtr hWnd, int id, int fsModifiers, int vlc); [DllImport("user32.dll")] public static extern bool

Now [from the Solution Explorer] open SystemHotkey.cs .
You also can see an empty page (SystemHotkey.c s page is empty).
Copy this code to the SystemHotkey.cs page:
Save your project.Code:using System; using System.ComponentModel; using System.Collections; using System.Diagnostics; using System.Windows.Forms; using Hotkey.Win32; namespace Hotkey.SystemHotkey { /// <summary> /// Handles a System Hotkey /// </summary> public class SystemHotkey : System.ComponentModel.Component, IDisposable { private System.ComponentModel.Container components = null; protected DummyWindowWithEvent m_Window = new DummyWindowWithEvent(); //window for WM_Hotkey Messages protected Shortcut m_HotKey = Shortcut.None; protected bool isRegistered = false; public event System.EventHandler Pressed; public event System.EventHandler Error; public SystemHotkey(System.ComponentModel.IContainer container) { container.Add(this); InitializeComponent(); m_Window.ProcessMessage += new MessageEventHandler(MessageEvent); } public SystemHotkey() { InitializeComponent(); if (!DesignMode) { m_Window.ProcessMessage += new MessageEventHandler(MessageEvent); } } public new void Dispose() { if (isRegistered) { if (UnregisterHotkey()) System.Diagnostics.Debug.WriteLine("Unreg: OK"); } System.Diagnostics.Debug.WriteLine("Disposed"); } #region Component Designer generated code /// <summary> /// Required method for Designer support - do not modify /// the contents of this method with the code editor. /// </summary> private void InitializeComponent() { components = new System.ComponentModel.Container(); } #endregion protected void MessageEvent(object sender, ref Message m, ref bool Handled) { //Handle WM_Hotkey event if ((m.Msg == (int)Win32.Msgs.WM_HOTKEY) && (m.WParam == (IntPtr)this.GetType().GetHashCode())) { Handled = true; System.Diagnostics.Debug.WriteLine("HOTKEY pressed!"); if (Pressed != null) Pressed(this, EventArgs.Empty); } } protected bool UnregisterHotkey() { //unregister hotkey return Win32.User32.UnregisterHotKey(m_Window.Handle, this.GetType().GetHashCode()); } protected bool RegisterHotkey(Shortcut key) { //register hotkey int mod = 0; Keys k2 = Keys.None; if (((int)key & (int)Keys.Alt) == (int)Keys.Alt) { mod += (int)Win32.Modifiers.MOD_ALT; k2 = Keys.Alt; } if (((int)key & (int)Keys.Shift) == (int)Keys.Shift) { mod += (int)Win32.Modifiers.MOD_SHIFT; k2 = Keys.Shift; } if (((int)key & (int)Keys.Control) == (int)Keys.Control) { mod += (int)Win32.Modifiers.MOD_CONTROL; k2 = Keys.Control; } System.Diagnostics.Debug.Write(mod.ToString() + " "); System.Diagnostics.Debug.WriteLine((((int)key) - ((int)k2)).ToString()); return Win32.User32.RegisterHotKey(m_Window.Handle, this.GetType().GetHashCode(), (int)mod, ((int)key) - ((int)k2)); } public bool IsRegistered { get { return isRegistered; } } [DefaultValue(Shortcut.None)] public Shortcut Shortcut { get { return m_HotKey; } set { if (DesignMode) { m_HotKey = value; return; } //Don't register in Designmode if ((isRegistered) && (m_HotKey != value)) //Unregister previous registered Hotkey { if (UnregisterHotkey()) { System.Diagnostics.Debug.WriteLine("Unreg: OK"); isRegistered = false; } else { if (Error != null) Error(this, EventArgs.Empty); System.Diagnostics.Debug.WriteLine("Unreg: ERR"); } } if (value == Shortcut.None) { m_HotKey = value; return; } if (RegisterHotkey(value)) //Register new Hotkey { System.Diagnostics.Debug.WriteLine("Reg: OK"); isRegistered = true; } else { if (Error != null) Error(this, EventArgs.Empty); System.Diagnostics.Debug.WriteLine("Reg: ERR"); } m_HotKey = value; } } } }
--------------------------
Now delete Program.cs from the solution explorer.
-------------------------------------------------------------------------
And open Form1.cs [From the design mode, View the Form1 Code].
And clear all Form1.cs code, and add this code to the Form1.cs:
[Wirte the code to Form1.cs]:
-------------Code:using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Text; using System.Windows.Forms; namespace HotkeyNameSpace { public partial class Form1 : Form { private System.Windows.Forms.Label label1; //Making a new Hotkey..... private Hotkey.SystemHotkey.SystemHotkey systemHotkey1; private System.Windows.Forms.Label label2; private System.ComponentModel.IContainer components; public Form1() { // // Required for Windows Form Designer support // InitializeComponent(); // // TODO: Add any constructor code after InitializeComponent call // } /// <summary> /// Clean up any resources being used. /// </summary> protected override void Dispose(bool disposing) { if (disposing) { if (components != null) { components.Dispose(); } } base.Dispose(disposing); } #region Windows Form Designer generated code /// <summary> /// Required method for Designer support - do not modify /// the contents of this method with the code editor. /// </summary> private void InitializeComponent() { this.components = new System.ComponentModel.Container(); this.systemHotkey1 = new Hotkey.SystemHotkey.SystemHotkey(this.components); this.label1 = new System.Windows.Forms.Label(); this.label2 = new System.Windows.Forms.Label(); this.SuspendLayout(); // // systemHotkey1 // this.systemHotkey1.Shortcut = System.Windows.Forms.Shortcut.CtrlR; //Here make your own Hotkey. this.systemHotkey1.Pressed += new System.EventHandler(this.systemHotkey1_Pressed); // // label1 // this.label1.Location = new System.Drawing.Point(64, 16); this.label1.Name = "label1"; this.label1.Size = new System.Drawing.Size(280, 96); this.label1.TabIndex = 0; this.label1.Text = "Waiting for events"; // // label2 // this.label2.Location = new System.Drawing.Point(72, 184); this.label2.Name = "label2"; this.label2.Size = new System.Drawing.Size(240, 72); this.label2.TabIndex = 1; this.label2.Text = "Use the SystemHotkey Component in Windows Forms designer to modify the Hotkey. Pr" + "ess Ctrl+R to fire the Hotkey event"; // // Form1 // this.AutoScaleBaseSize = new System.Drawing.Size(5, 13); this.ClientSize = new System.Drawing.Size(400, 286); this.Controls.Add(this.label2); this.Controls.Add(this.label1); this.Name = "Form1"; this.Text = "Form1"; this.ResumeLayout(false); } #endregion /// <summary> /// The main entry point for the application. /// </summary> [STAThread] static void Main() { Application.EnableVisualStyles(); Application.SetCompatibleTextRenderingDefault(false); Application.Run(new Form1()); } private void systemHotkey1_Pressed(object sender, System.EventArgs e) { label1.Text = "Hotkey Pressed!"; MessageBox.Show("Hotkey pressed...", "Attention", MessageBoxButtons.OK, MessageBoxIcon.Warning); this.Activate(); this.BringToFront(); } } }
You can see from [the solution explorer] the Form1 icon, at the left of the icon: you can see a Plus Sign, click on the plus sign: you see the Form1 has two files [The first is Form1.Designer. cs, the second is Form1.resx].
So delete the Form1.Designer. cs.
--------------------------------------------------
And run your application (When the application running press Ctrl+R).
If you want to change the hotkey (or make another), you can see in Form1.cs.
Do not edit Hotkey.cs and SystemHotkey.cs .
Goodbye.Comment
