Thread.Parent Property

Gets the immediate parent object of a Thread object.

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

Syntax

'Declaration
ReadOnly Property Parent As Debugger

'Usage
Dim instance As Thread 
Dim value As Debugger 

value = instance.Parent

Debugger Parent { get; }

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

function get Parent () : Debugger

Property Value

Type: EnvDTE.Debugger
A Debugger object.

Remarks

The Parent property returns the immediate parent to the Thread 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. Set the breakpoint inside the worker thread callback method.

2. Run the target application in the debug mode.

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

public static void TestThreadProperties(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("Thread Test");
    owp.Activate();

    EnvDTE.Threads threads = dte.Debugger.CurrentProgram.Threads;
    owp.OutputString("\nNumber of items in the Thread collection: " + 
                     threads.Item(1).Collection.Count + "\n");
    foreach(EnvDTE.Thread thread in threads)
    {
        owp.OutputString("\nThread: " + thread.ID + "  Name: " + thread.Name);
        owp.OutputString("\n  Edition of the environment : " + thread.DTE.Edition);
        owp.OutputString("\n  Is alive                   : " + thread.IsAlive);
        owp.OutputString("\n  Is frozen                  : " + thread.IsFrozen);
        owp.OutputString("\n  Location                   : " + thread.Location);
        owp.OutputString("\n  Parent's current mode      : " + thread.Parent.CurrentMode);
        owp.OutputString("\n  Priority                   : " + thread.Priority);
        owp.OutputString("\n  Program name               : " + thread.Program.Name);
        owp.OutputString("\n  Number of stack frames     : " + thread.StackFrames.Count);
        owp.OutputString("\n  Suspended number of times  : " + thread.SuspendCount);
    }
}
