CodeModel2.AddDelegate Method

Creates a new delegate code construct and inserts the code in the correct location.

Namespace:  EnvDTE80
Assembly:  EnvDTE80 (in EnvDTE80.dll)

Syntax

'Declaration
Function AddDelegate ( _
    Name As String, _
    Location As Object, _
    Type As Object, _
    Position As Object, _
    Access As vsCMAccess _
) As CodeDelegate

CodeDelegate AddDelegate(
    string Name,
    Object Location,
    Object Type,
    Object Position,
    vsCMAccess Access
)

CodeDelegate^ AddDelegate(
    String^ Name, 
    Object^ Location, 
    Object^ Type, 
    Object^ Position, 
    vsCMAccess Access
)

abstract AddDelegate : 
        Name:string * 
        Location:Object * 
        Type:Object * 
        Position:Object * 
        Access:vsCMAccess -> CodeDelegate

function AddDelegate(
    Name : String, 
    Location : Object, 
    Type : Object, 
    Position : Object, 
    Access : vsCMAccess
) : CodeDelegate

Parameters

• Name
  Type: String

  Required. The name of the delegate to add.

• Location
  Type: Object

  Required. The path and file name for the new delegate definition. Depending on the language, the file name is either relative or absolute to the project file. The file is added to the project if it is not already a project item. If the file cannot be created and added to the project, then AddDelegate fails.

• Type
  Type: Object

  Required. A vsCMTypeRef constant indicating the data type that the function returns. This value can be a CodeTypeRef object, a vsCMTypeRef constant, or a fully qualified type name.

• Position
  Type: Object

  Optional. Default = 0. The code element after which to add the new element. If the value is a CodeElement, then the new element is added immediately after it.

  If the value is a Long data type, then AddDelegate indicates the element after which to add the new element.

  Because collections begin their count at 1, passing 0 indicates that the new element should be placed at the beginning of the collection. A value of -1 means the element should be placed at the end.

• Access
  Type: EnvDTE.vsCMAccess

  Optional. A vsCMAccess constant.

Return Value

Type: EnvDTE.CodeDelegate
A CodeDelegate object.

Remarks

Native Visual C++ requires the colon-separated (::) format for its fully qualified type names. All other languages support the period-separated format.

The correctness of the arguments is determined by the language behind the code model.

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

Sub AddDelegateExample2(ByVal dte As DTE2)

    ' Before running this example, open a code document from a project.
    Try
        Dim projItem As ProjectItem = dte.ActiveDocument.ProjectItem
        Dim cm As CodeModel = projItem.ContainingProject.CodeModel

        ' Create a new delegate.
        cm.AddDelegate("TestDelegate", projItem.Name, _
            vsCMTypeRef.vsCMTypeRefInt)
    Catch ex As Exception
        MsgBox(ex.Message)
    End Try

End Sub

public void AddDelegateExample2(DTE2 dte)
{
    // Before running this example, open a code document from 
    // a project.
    try
    {
        ProjectItem projItem = dte.ActiveDocument.ProjectItem;
        CodeModel cm = projItem.ContainingProject.CodeModel;

        // Create a new delegate.
        cm.AddDelegate("TestDelegate", projItem.Name, 
            vsCMTypeRef.vsCMTypeRefInt, -1, 
            vsCMAccess.vsCMAccessPublic);
    }
    catch (Exception ex)
    {
        MessageBox.Show(ex.Message);
    }
}
