Examples

The following example demonstrates how to use the Freeze method.

To test this method:

  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 FreezeThawTest(DTE2 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 Freeze Thaw 
      Test");
    owp.Activate();

    EnvDTE.Threads threads = dte.Debugger.CurrentProgram.Threads;
    owp.OutputString("There are " + threads.Count + " threads:\n");
    foreach(EnvDTE90.Thread2 thread in threads)
    {
        owp.OutputString("\nThread: " + thread.ID + "  Name: " + 
          thread.Name);
        owp.OutputString("\n  Is frozen                  : " + 
          thread.IsFrozen);
        owp.OutputString("\n  Freezing . . . ");
        thread.Freeze();
        owp.OutputString("\n  Is frozen                  : " + 
          thread.IsFrozen);
        owp.OutputString("\n  Thawing . . . ");
        thread.Thaw();
        owp.OutputString("\n  Is frozen                  : " + 
          thread.IsFrozen);
    }
}
