Debugger3.LastBreakReason Property

Gets the last reason that a program was broken. If the program is running it returns DBG_REASON_NONE.

Namespace:  EnvDTE90
Assembly:  EnvDTE90 (in EnvDTE90.dll)

Syntax

'Declaration
ReadOnly Property LastBreakReason As dbgEventReason

dbgEventReason LastBreakReason { get; }

property dbgEventReason LastBreakReason {
    dbgEventReason get ();
}

abstract LastBreakReason : dbgEventReason with get

function get LastBreakReason () : dbgEventReason

Property Value

Type: EnvDTE.dbgEventReason
A dbgEventReason value.

Remarks

A program can be broken, for example, for some of the following reasons:

• A breakpoint was hit. Gets dbgEventReasonBreakpoint.

• An exception was thrown. Gets dbgEventReasonExceptionThrown.

• An exception was thrown but not handled by the program being debugged. Gets dbgEventReasonExceptionNotHandled.

If nothing is being debugged or the debugger is in run mode, this property returns dbgEventReasonNone.

For a complete list of enumerations, see dbgEventReason.

Examples

The following example shows 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(EnvDTE80.DTE2 dte)
{
    // Setup 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: ");
    EnvDTE90.Debugger3 debugger = (EnvDTE90.Debugger3)dte.Debugger;
    switch (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;
    }
}

Sub LastBreakReason()
    ' This function shows the reason break mode was entered
    ' in the Output window.
    Dim ow As OutputWindow
    ow = DTE2.Windows.Item(Constants.vsWindowKindOutput).Object

    Select Case DTE2.Debugger.LastBreakReason
        Case dbgEventReason.dbgEventReasonBreakpoint
            ow.ActivePane.OutputString("Breakpoint hit" + vbCrLf)

        Case dbgEventReason.dbgEventReasonNone
            ow.ActivePane.OutputString("No reason" + vbCrLf)

        Case dbgEventReason.dbgEventReasonExceptionNotHandled
            ow.ActivePane.OutputString("Exception not handled by the _
            debuggee" + vbCrLf)

        Case dbgEventReason.dbgEventReasonExceptionThrown
            ow.ActivePane.OutputString("Exception thrown" + vbCrLf)
    End Select
End Sub
