Assembly: EnvDTE (in EnvDTE.dll)
Syntax
'Declaration
ReadOnly Property LastBreakReason As dbgEventReason
dbgEventReason LastBreakReason { get; }

Property Value
Type: EnvDTE.dbgEventReason
A dbgEventReason value.
Remarks
LastBreakReason returns a dbgEventReason value indicating why a program broke. A program can be broken for one of the following reasons:
A breakpoint was hit.
Returns a dbgEventReasonBreakpoint.
An exception was thrown.
Returns a dbgEventReasonExceptionThrown.
An exception was thrown but not handled by the program being debugged.
Returns a dbgEventReasonExceptionNotHandled.
If nothing is being debugged or the debugger is in run mode, this property returns dbgEventReasonNone.
Examples
The following example demonstrates how to use the LastBreakReason property.
To test this property:
Set a breakpoint in the target application. Run the add-in.
Run the target application in the debug mode.
Run the add-in.
public static void LastBreakReason(DTE dte)
{
// Setup the 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("Last Break Reason Test");
owp.Activate();
owp.OutputString("The reason that a program was broken: ");
switch(dte.Debugger.LastBreakReason)
{
case dbgEventReason.dbgEventReasonBreakpoint:
owp.OutputString("Breakpoint hit.");
break;
case dbgEventReason.dbgEventReasonNone:
owp.OutputString("No reason");
break;
case dbgEventReason.dbgEventReasonExceptionNotHandled:
owp.OutputString("Exception not handled by the debuggee");
break;
case dbgEventReason.dbgEventReasonExceptionThrown:
owp.OutputString("Exception thrown");
break;
}
}
