Assembly:  EnvDTE (in EnvDTE.dll)

Syntax

'Declaration
ReadOnly Property LastBreakReason As dbgEventReason
'Usage
Dim instance As Debugger 
Dim value As dbgEventReason 

value = instance.LastBreakReason
dbgEventReason LastBreakReason { get; }
property dbgEventReason LastBreakReason {
    dbgEventReason get ();
}
function get LastBreakReason () : dbgEventReason

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:

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:

  1. Set a breakpoint in the target application. Run the add-in.

  2. Run the target application in the debug mode.

  3. 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;
    }
}
