_DTE.ActiveDocument Property

Gets the active document.

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

abstract ActiveDocument : Document with get

Property Value

Type: EnvDTE.Document
A Document object.

An active document is one that has the focus. To make another document active, set the focus on its window.

You can set the caption only on Tool windows. If you attempt to set the caption on other window types, such as Document windows, you get the error, "Unspecified error."

The active document property throws an exception when the project Properties window is opened in Microsoft Visual Studio 2005.

For readability, the following code example does not contain security checking or complete error handling. Do not use the following code in a production environment.

Sub ActiveDocumentExample()
  Dim objTextDoc As TextDocument
  Dim objEP As EditPoint
  
  'Create a new text document.
  Call DTE.ItemOperations.NewFile("General\Text File")
  'Get a handle to the new document.
  Set objTextDoc = DTE.ActiveDocument.Object("TextDocument")
  Set objEP = objTextDoc.StartPoint.CreateEditPoint
  'Create an EditPoint and add some text.
  objEP.Insert "A test sentence."
End Sub

Sub DocumentExample()
  Dim doc As Document
  Dim desc As String

  Set doc = DTE.ActiveDocument
  desc = "You are editing a "
  If (doc.ReadOnly) Then
    desc = desc & "read-only"
  Else
    desc = desc & "writable"
  End If
  desc = desc & " document called " & doc.Name & " located at " & doc.Path
  MsgBox desc
End Sub
