Examples
The following example demonstrates how to use the OnContextChanged event.
To test this event:
Open the target application.
Run the add-in.
Observe the message box: "Events are attached."
Set a breakpoint and run the target application in the debug mode.
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.");
}
