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

    EnvDTE.Threads threads = dte.Debugger.CurrentProgram.Threads;
    owp.OutputString("There are " + threads.Count + " threads:\n");
    foreach(EnvDTE.Thread 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);
    }
}
Shared Sub FreezeThawTest(ByRef dte As EnvDTE.DTE)
    Dim str As String
    Dim threads As EnvDTE.Threads = dte.Debugger.CurrentProgram.Threads
    str = "There are " + threads.Count.ToString() + " threads running."
    For Each thread As EnvDTE.Thread In threads
        str += vbCrLf + vbCrLf + "  Thread: " + thread.ID.ToString()
