add shortcut to my program when right click - windows

Question

Im not sure what the exact term should i called. I want to add shortcut to my C# program when i right click in windows.
From my findings, it got something to do with configure the "regedit". I have this example, but it was made for IE. can anyone point me to any references that can solve my problems?

thank you very much.
UPDATED today..
Based on response from Factor Mystic, i add this code to the original. I have 2 solutions. One, It was created in registry HKEY_ CLASSES_ ROOT, but i cannot see the result when i right click the doc files.
private const string ProgName = "Software\\Classes\\Word.Document\\shell";
private const string MenuName = "Software\\Classes\\Word.Document\\shell\\NewTesting";
public const string Command =Software\\Classes\\Word.Document\\shell\\NewTesting\\command";
private void Form1_Load(object sender, EventArgs e)
{
txtProgram.Text = "Word.Document.8";
txtName.Text = "Testing";
txtPath.Text = "C:\\temp\\encriptTest.exe";
check();
addItem()
}
public void check()
{
RegistryKey regmenu = null;
RegistryKey regcmd = null;
try
{
//this.CheckSecurity();
regmenu = Registry.ClassesRoot.OpenSubKey(MenuName, false);
}
catch (ArgumentException ex)
{
// RegistryPermissionAccess.AllAccess can not be used as a parameter for GetPathList.
MessageBox.Show(this, "An ArgumentException occured as a result of using AllAccess. "
+ "AllAccess cannot be used as a parameter in GetPathList because it represents more than one "
+ "type of registry variable access : \n" + ex);
}
catch (SecurityException ex)
{
// RegistryPermissionAccess.AllAccess can not be used as a parameter for GetPathList.
MessageBox.Show(this, "An ArgumentException occured as a result of using AllAccess. " + ex);
this.btnAddMenu.Enabled = false;
//this.btnRemoveMenu.Enabled = false;
}
catch (Exception ex)
{
MessageBox.Show(this, ex.ToString());
}
finally
{
if (regmenu != null)
regmenu.Close();
if (regcmd != null)
regcmd.Close();
}
}
private void CheckSecurity()
{
//check registry permissions
RegistryPermission regPerm;
regPerm = new RegistryPermission(RegistryPermissionAccess.Write, "HKEY_CLASSES_ROOT\\" + ProgName);
regPerm.AddPathList(RegistryPermissionAccess.Write, "HKEY_CLASSES_ROOT\\" + MenuName);
regPerm.AddPathList(RegistryPermissionAccess.Write, "HKEY_CLASSES_ROOT\\" + Command);
regPerm.Demand();
}
private void addItem()
{
RegistryKey regmenu = null;
RegistryKey regcmd = null;
RegistryKey regprog = null;
try
{
regprog = Registry.ClassesRoot.CreateSubKey(ProgName);
if (regmenu != null)
regmenu.SetValue("", this.txtProgram.Text);
regmenu = Registry.ClassesRoot.CreateSubKey(MenuName);
if (regmenu != null)
regmenu.SetValue("", this.txtName.Text);
regcmd = Registry.ClassesRoot.CreateSubKey(Command);
if (regcmd != null)
regcmd.SetValue("", this.txtPath.Text);
}
catch (Exception ex)
{
MessageBox.Show(this, ex.ToString());
}
finally
{
if (regprog != null)
regprog.Close();
if (regmenu != null)
regmenu.Close();
if (regcmd != null)
regcmd.Close();
}
}
Second, create in HKEY_ LOCAL_ MACHINE.
private bool Add_Item(string Extension,string MenuName, string MenuDescription, string MenuCommand)
{
//receive .doc,OpenTest,Open with Opentest,path: C:\\temp\\encriptTest.exe %1
bool ret = false;
RegistryKey rkey = //receive .doc extension (word.Document.8)
Registry.ClassesRoot.OpenSubKey(Extension); //set HKEY_LOCAL_MACHINE\software\classes\word.Document.8
if (rkey != null)
{
string extstring = rkey.GetValue("").ToString();
rkey.Close();
if (extstring != null)
{
if (extstring.Length > 0)
{
rkey = Registry.ClassesRoot.OpenSubKey(extstring, true);
if (rkey != null) //with extension file receive OpenTest as shell
{
string strkey = "shell\\" + MenuName + "\\command"; //..\shell\OpenTest\command
RegistryKey subky = rkey.CreateSubKey(strkey);
if (subky != null)
{
subky.SetValue("", MenuCommand); // path: C:\\temp\\encriptTest.exe %1
subky.Close();
subky = rkey.OpenSubKey("shell\\" + MenuName, true); //..\shell\OpenTest
if (subky != null)
{
subky.SetValue("", MenuDescription); // name displayed: Open with &OpenTest
subky.Close();
}
ret = true;
}
rkey.Close();
}
}
}
}
return ret;
}
}
My concerned, which Main Key should i use?

Answer 1

I believe you want to add items to the Explorer context menu.
Here is a nice article on CodeProject that shows you how to do it:
http://www.codeproject.com/KB/cs/appendmenu.aspx (basically it's just adding the appropriate keys to the windows registry)

Answer 2

You're going to want to determine the file type (ProgID) of .doc files. You can find this in HKEY_CURRENT_USER\Software\Classes\.doc (it is the default value).
Then add the key HKEY_CURRENT_USER\Software\Classes\<ProgID>\shell\NewMenuOption\command, where the default value is the path to your program.
You can do all this with Registry.SetValue and GetValue.
Check out this msdn page to get started.
Edit: Additional info, the difference between hive keys:
HKEY_LOCAL_MACHINE\Software\Classes and HKEY_CURRENT_USER\Software\Classes are similar, but HKLM is for system defaults/all user settings, and HKCU is for per user settings. Per user settings don't require elevated privileges, so you can write your context menu keys as a regular user with no pain.
HKEY_CLASSES_ROOT is a view combining HKEY_LOCAL_MACHINE\Software\Classes and HKEY_CURRENT_USER\Software\Classes, with writes directed to HKLM. This is a shortcut to writing system default values, and many tutorials show this because it's slightly simpler, but unless you're installing the application for all users I don't recommend it.

Thank you very much for the responses. Very2 apreciate Them..
As Per Conlcusion, 3 ways on solving my prob. in easy understadable approach:
Adding shortcut in 3 ways:
1. create directly in registry window:

2. shortcut available only to folders.

3. shortcut available to all files and folders.
