Examples

The following example demonstrates how to use the IsAlive property.

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);  
    }  
}

    str = "Number of items in the Thread collection: " + _

    For Each thread As EnvDTE.Thread In threads  
        str += vbCrLf + vbCrLf + "  Thread: " + thread.ID.ToString()

        str += vbCrLf + "    Is alive: " + thread.IsAlive.ToString()  
        str += vbCrLf + "    Is frozen: " + thread.IsFrozen.ToString()  
        str += vbCrLf + "    Location: " + thread.Location  
        str += vbCrLf + "    Parent's current mode: " + _  
               thread.Parent.CurrentMode.ToString()  
        str += vbCrLf + "    Priority: " + thread.Priority  
        str += vbCrLf + "    Program name: " + thread.Program.Name  
        str += vbCrLf + "    Number of stack frames: " + _  
               thread.StackFrames.Count.ToString()  
        str += vbCrLf + "    Suspended number of times: " + _  
               thread.SuspendCount.ToString()  
    Next  
    MessageBox.Show(str, "Thread Test - Properties")  
End Sub  

Remarks

Returns true if the referenced thread is still alive; otherwise, false.

Note

The thread state may change before this function returns.
