StackFrame.Parent Property

Gets the immediate parent object of a StackFrame object.

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

Syntax

'Declaration
ReadOnly Property Parent As Thread

Thread Parent { get; }

property Thread^ Parent {
    Thread^ get ();
}

abstract Parent : Thread

function get Parent () : Thread

Property Value

Type: EnvDTE.Thread
A Thread object.

Remarks

The Parent property returns the immediate parent to the StackFrame object. To get the containing collection, use the Collection property.

Examples

The following example demonstrates how to use the Parent property.

To test this property

1. In your target application, set a breakpoint inside the method other than the method Main().

2. Run the target application in the debug mode.

3. When the application stops on the breakpoint, run the add-in.

public static void TestStackFrames(DTE dte)
{
    // Setup debug Output window.
    Window w = (Window)dte.Windows.Item(EnvDTE.Constants.vsWindowKindOutput);
    w.Visible = true;
    OutputWindow ow = (OutputWindow)w.Object;
    OutputWindowPane owp = ow.OutputWindowPanes.Add("Stack Frames Test");
    owp.Activate();

    EnvDTE.StackFrames stackFrames = dte.Debugger.CurrentThread.StackFrames;
    owp.OutputString("\nNumber of items in the Current Stack collection: " + 
                     stackFrames.Item(1).Collection.Count + "\n");

    foreach(EnvDTE.StackFrame sf in stackFrames)
    {
        owp.OutputString("\nStack Frame: " + sf.FunctionName);
        owp.OutputString("\n  Edition of the environment : " + sf.DTE.Edition);
        owp.OutputString("\n  Language                   : " + sf.Language);
        owp.OutputString("\n  Locals");
        EnvDTE.Expressions expressions = sf.Locals;
        foreach(EnvDTE.Expression exp in expressions)
            owp.OutputString("\n    " + exp.Name + " = " + exp.Value);
        owp.OutputString("\n  Module                     : " + sf.Module);
        owp.OutputString("\n  Current Thread ID          : " + sf.Parent.ID);
        owp.OutputString("\n  Return Type                : " + sf.ReturnType);
    }
}
