Examples

The following example demonstrates how to use the LastBreakReason property.

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;  
    }  
}

Shared Sub LastBreakReason(ByRef dte As EnvDTE.DTE)  
    Select Case dte.Debugger.LastBreakReason  
        Case dbgEventReason.dbgEventReasonBreakpoint  
            MessageBox.Show("Breakpoint hit.", "Debugger Test - LastBreakReason")  
        Case dbgEventReason.dbgEventReasonNone  
            MessageBox.Show("No reason", "Debugger Test - LastBreakReason")  
        Case dbgEventReason.dbgEventReasonExceptionNotHandled  
            MessageBox.Show("Exception not handled by the debuggee", _  
                            "Debugger Test - LastBreakReason")  
        Case dbgEventReason.dbgEventReasonExceptionThrown  
            MessageBox.Show("Exception thrown", "Debugger Test - LastBreakReason")  
    End Select  
End Sub

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.
