Examples

Sub CodeElementFromPointExample(ByVal dte As DTE2)  

    ' Before running this example, open a code document from a project  
    ' and place the insertion point anywhere inside the source code.

            & vbCrLf & vbCrLf & elems)  
End Sub

public void CodeElementFromPointExample(DTE2 dte)  
{  
    // Before running this example, open a code document from a project  
    // and place the insertion point anywhere inside the source code.  
    TextSelection sel =   
        (TextSelection)dte.ActiveDocument.Selection;  
    TextPoint pnt = (TextPoint)sel.ActivePoint;  
    // Discover every code element containing the insertion point.  
    FileCodeModel fcm =   
    dte.ActiveDocument.ProjectItem.FileCodeModel;  
    string elems = "";  
    vsCMElement scopes = 0;  
    foreach (vsCMElement scope in Enum.GetValues(scopes.GetType()))  
    {  
        try  
        {  
            CodeElement elem = fcm.CodeElementFromPoint(pnt, scope);  
            elems += elem.Name + " (" + scope.ToString() + ")\n";  
        }  
        catch (COMException ex)  
        {  
            //don’t do anything – this is expected if there is   
            //no code element in the scope  
        }  
    }  
    MessageBox.Show(  
        "The following elements contain the insertion point:\n\n" +   
        elems);  
}

Remarks

CodeElementFromPoint returns the code element associated with the TextPoint based on the specified scope or granularity of containment. If no code element of the specified type contains the editor ___location, then CodeElementFromPoint fails.
