function AddEvent(
    Name : String, 
    FullDelegateName : String, 
    CreatePropertyStyleEvent : boolean, 
    Location : Object, 
    Access : vsCMAccess
) : CodeEvent

Parameters

  • Name
    Type: System.String

    Required. Name of the class event to add.

  • FullDelegateName
    Type: System.String

    Required. Name of the delegate to base the event on. This acts as a template for the new event handler.

  • CreatePropertyStyleEvent
    Type: System.Boolean

    Optional. Creates an event that has a property style accessor. True indicates that the event should have an accessor, false indicates that it should not.

Return Value

Type: EnvDTE80.CodeEvent
Returns the class event handler that was created.

Note

The values of code model elements such as classes, structs, functions, attributes, delegates, and so forth can be non-deterministic after making certain kinds of edits, meaning that their values cannot be relied upon to always remain the same. For more information, see the section Code Model Element Values Can Change in Discovering Code by Using the Code Model (Visual Basic).

Examples

[Visual Basic]

Sub AddEventExample(ByVal dte As DTE2)
    ' Before running this example, open a code document from a project
    ' and place the insertion point inside a class definition.
    Try
        ' Retrieve the CodeClass at the insertion point.
        Dim sel As TextSelection = _
            CType(dte.ActiveDocument.Selection, TextSelection)
        Dim cls As CodeClass = _
            CType(sel.ActivePoint.CodeElement( _
            vsCMElement.vsCMElementClass), CodeClass)

        ' Create a new event handler.
        cls.AddEvent("NewOnConnection", "OnConnection", True, -1, 
          vsCMAccess.vsCMAccessPublic)
    Catch ex As Exception
        MsgBox(ex.Message)
    End Try
End Sub

[C#]

public void AddEventExample(DTE2 dte)
{
    // Before running this example, open a code document from a project
    // and place the insertion point inside a class definition.
    try
    {
        // Retrieve the CodeClass at the insertion point.
        TextSelection sel = 
            (TextSelection)dte.ActiveDocument.Selection;
        CodeClass cls = 
            (CodeClass)sel.ActivePoint.get_CodeElement(
            vsCMElement.vsCMElementClass);
        // Creates a new event handler.
        cls.AddEvent("NewOnConnection", "OnConnection", true, -1, 
          vsCMAccess.vsCMAccessPublic);
    }
    catch (Exception ex)
    {
        MessageBox.Show(ex.Message);
    }
