  1. POSubscription to DTE events doesn't seem to work - Events don't get called
    text
    copied!<p>I've made an extension inside a package and I am calling the following code (occurs when a user presses a button in the toolbar):</p> <pre><code>DocumentEvents documentEvents = (DTE2)GetService(typeof(DTE)); _dte.Events.DebuggerEvents.OnEnterBreakMode += DebuggerEvents_OnEnterBreakMode; _dte.Events.DebuggerEvents.OnEnterDesignMode += DebuggerEvents_OnEnterDesignMode; _dte.Events.DebuggerEvents.OnContextChanged += DebuggerEvents_OnContextChanged; _dte.Events.DocumentEvents.DocumentSaved += new _dispDocumentEvents_DocumentSavedEventHandler(DocumentEvents_DocumentSaved); _dte.Events.DocumentEvents.DocumentOpened += new _dispDocumentEvents_DocumentOpenedEventHandler(DocumentEvents_DocumentOpened); void DocumentEvents_DocumentOpened(Document Document) { } void DocumentEvents_DocumentSaved(Document Document) { } void DebuggerEvents_OnEnterBreakMode(dbgEventReason Reason, ref dbgExecutionAction ExecutionAction) { } void DebuggerEvents_OnContextChanged(Process NewProcess, Program NewProgram, Thread NewThread, StackFrame NewStackFrame) { } private void DebuggerEvents_OnEnterDesignMode(dbgEventReason reason) { } </code></pre> <p>The first and the major problem is that the subscription to the event doesn't work. I've tried:</p> <ul> <li>Opening new documents </li> <li>Detaching from debug (thus supposedly triggering OnEnterDesignMode </li> <li>Saving a document</li> </ul> <p>None of these seem to have any effect and the callback functions were never called.</p> <p>The second issue is that the subscription to the event line works USUALLY (the subscription itself, the callback doesn't work as described above) but after a while running the subscription line, e.g:</p> <pre><code>_dte.Events.DebuggerEvents.OnEnterBreakMode -= DebuggerEvents_OnEnterBreakMode; </code></pre> <p>Causes an exception:</p> <pre><code>Exception occured! System.Runtime.InteropServices.InvalidComObjectException: COM object that has been separated from its underlying RCW cannot be used. at System.StubHelpers.StubHelpers.StubRegisterRCW(Object pThis, IntPtr pThread) at System.Runtime.InteropServices.UCOMIConnectionPoint.Unadvise(Int32 dwCookie) at EnvDTE._dispDebuggerEvents_EventProvider.remove_OnEnterDesignMode(_dispDebuggerEvents_OnEnterDesignModeEventHandler A_1) </code></pre> <p>Any ideas will be welcome</p> <p>Thanks!
