The following example displays a message box if, for example, you try to create more than one KeychainItem for the same application.

Var newItem As KeychainItem
If System.KeychainCount > 0 Then
  newItem = New KeychainItem
  // Indicate the name of the application
  newItem.ServiceName = "MyApplication"

  // Create a new keychain item for the application and assign the password
  System.Keychain.AddPassword(newItem, "SecretPassword")
Else
  System.Beep
  MessageBox("You don't have a key chain.")
End If
Exception err As KeychainException
  MessageBox(err.Message + ". Error Code: " + err.ErrorNumber.ToString)

MenuHasParentException.Message

Method descriptions

MenuHasParentException.Constructor

Constructor(message As String = "", errorCode As Integer = 0)

Note

Constructors are special methods called when you create an object with the New keyword and pass in the parameters above.

Used to raise your own RuntimeException with a message and optional error code.

MenuHasParentException.Stack

Stack As String

Returns a String array that contains a list of all of the methods in the stack from the main entrypoint to the point at which the exception was invoked.

The stack contains all the method names up and including the current method name.

This feature only works if the IncludeFunctionNames property on the App object is selected in the Shared Build Settings.

In addition to your own method calls, you will also see framework method calls, but these may not always be completely accurate due to insufficient symbols for the OS to resolve.

MenuHasParentException.StackFrames

StackFrames As StackFrame

Returns an array containing the stack when the exception was first raised.

Sample code

Whenever you need to use the same MenuItem in different places, use the Clone method to create a new copy of the MenuItem and its children, if any.

Var mi As New DesktopMenuItem("My menu item")
Var myClone As DesktopMenuItem

myClone = mi.Clone //Creates an independent copy of "mi"

Compatibility

All project types on all supported operating systems.
