Window2.DTE Property

Gets the top-level extensibility object.

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

Syntax

'Declaration
ReadOnly Property DTE As DTE
DTE DTE { get; }
property DTE^ DTE {
    DTE^ get ();
}
abstract DTE : DTE with get
function get DTE () : DTE

Property Value

Type: EnvDTE.DTE
A DTE object.

Remarks

In Visual Studio, the DTE object is the root of the automation model, which other object models often call "Application".

Examples

This example uses the DTE object, obtained through a Window2 object, to determine whether an Output Window belongs to the Macros IDE, or Visual Studio IDE.

For more information about how to run this example as an add-in, see How to: Compile and Run the Automation Object Model Code Examples.
