CodeAttribute2.DTE Property

Gets the top-level extensibility object.

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

Syntax

'Declaration
ReadOnly Property DTE As DTE

'Usage
Dim instance As CodeAttribute2 
Dim value As DTE 

value = instance.DTE

DTE DTE { get; }

property DTE^ DTE {
    DTE^ get ();
}

function get DTE () : DTE

Property Value

Type: EnvDTE.DTE
A DTE object.

Implements

CodeAttribute.DTE

Remarks

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

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

The following example creates a new namespace and attribute in the current class and lists some of the attribute's properties.

public void CreateClassAndAttrib(DTE2 applicationObject)
{
    // Before running, load or create a project.
    FileCodeModel2 fcm2 = GetFileCodeModel(applicationObject);
    CodeAttribute2 cmAttribute;
    CodeClass2 cmClass;
    String msg = null;

    if (fcm2 != null)
    {
        CodeNamespace cmNamespace;
        // Try to create a new namespace.
        try
        {
            cmNamespace = fcm2.AddNamespace("CMNamespace", -1);
            // If successful, create the other code elements.
            if (cmNamespace != null)
            {
                cmClass = (CodeClass2)cmNamespace.AddClass("ANewClass", 
                -1, null, null, vsCMAccess.vsCMAccessPrivate);
                cmAttribute = (CodeAttribute2)cmClass.AddAttribute
                ("NewAttribute", "AttributeValue", -1);
                msg += "Attribute count: " + 
                cmAttribute.Collection.Count + Environment.NewLine;
                msg += "Document name: " + 
                cmAttribute.DTE.ActiveDocument.Name;
            }
            else
            {
                MessageBox.Show("Cannot continue - no filecodemodel 
                available.");
            }
        }
        catch (Exception ex)
        {
            MessageBox.Show("ERROR: " + ex);
        }
    }
}

public FileCodeModel2 GetFileCodeModel(DTE2 applicationObject)
{
    // Returns the FileCodeModel object of the active 
    // window.
    TextWindow txtWin = 
    (TextWindow)applicationObject.ActiveWindow.Object;
    FileCodeModel2 fcm2;
    if (txtWin != null)
    {
        try
        {
             fcm2 = (FileCodeModel2)txtWin.Parent.
             ProjectItem.FileCodeModel;
             return fcm2;
        }
        catch (Exception ex)
        {
             MessageBox.Show("ERROR: " + ex);
             return null;
        }
    }
    else
        return null;
}
