'Usage
Dim instance As DebuggerEventsClass 
Dim handler As _dispDebuggerEvents_OnContextChangedEventHandler 

AddHandler instance.OnContextChanged, handler
public virtual event _dispDebuggerEvents_OnContextChangedEventHandler OnContextChanged

_dispDebuggerEvents_Event.OnContextChanged

Examples

The following example demonstrates how to use the OnContextChanged event.

To test this event:

  1. Open the target application.

  2. Run the add-in.

    Observe the message box: "Events are attached."

  3. Set a breakpoint and run the target application in the debug mode.

  4. When the application stops at the breakpoint, stop the debugger.

    Observe the message box: "Debugger enters context changed mode."

// Place the following code in the Exec method of the add-in:
EnvDTE.DebuggerEvents debugEvents = applicationObject.Events.DebuggerEvents;
debugEvents.OnContextChanged += 
new _dispDebuggerEvents_OnContextChangedEventHandler(DebuggerEvents.ContextHandler);

// Place the following Event handler code in the add-in:
// Needed to activate event handlers in Connect.Exec.
public static void StartEvents(DTE dte)
{
    System.Windows.Forms.MessageBox.Show("Events are attached.");
}

public static void ContextHandler(EnvDTE.Process newProc, 
    EnvDTE.Program newProg, EnvDTE.Thread newThread, EnvDTE.StackFrame newStkFrame)
{
    System.Windows.Forms.MessageBox.Show("Debugger enters context changed mode.");
}
