.NET Forum / Visual Studio.NET / Extensibility / June 2006How to remove named command?
I have a toolbar with 3 buttons, each button is created by EnvDTE::Command::AddControl() after the command has been added to the visual studio 2005 environment via AddNamedCommand(). The problem I have is that I don't want these commands to be accessible anywhere else in the environment. So here are my questions: 1. is there any other way to create a toolbar button or menu button associated with a command that's NOT publicised anywhere in the enviroment (ie Tools/Customize...)? I've read something about an unnamed command in another post but have not been able to find a way to create it. 2. If 1 is false, is there a way to programmatically remove these named commands? I would do that in my addin's OnDisconnection(). Thanks!

Maybe using the VSIP / VS 2005 SDK you can create unnamed commands with GUID and ID. Alternatively you can create buttons without a command using the old way: objCommandBarButton = CommandBar.Controls.Add(...). You get an event handler for the Click event, etc. > 2.

Unfortunately if I try to pass anything but the value '1' for the id (the second parameter) it fails to add. I don't see any type of event handling in CommandBarButton, the only method that looks remotelylike one is OnAction() which takes a string and doesn't seem to work unless it's in Visual Basic. How do I hook the OnClick event for the button? Thanks! Hi, - About CommandBar.Controls.Add(...), most parameters are optional. Just pass the control type (msoControlButton) in the first parameter. - About the event handling, there are two ways: 1) Cast the returned CommandBarControl to CommandBarButton, which has a Click Event. 2) Use DTE.Events.CommandBarEvents(objCommandBarControl), cast to EnvDTE.CommandBarEvents if needed, and you get the Click event.

It looks really simple to use, unfortunately I'm writing this in C++ (not by choice!) and it isn't as simple from what I can tell. My addin implements this interface: IDispEventImpl<0, CConnect, &EnvDTE::DIID__dispCommandBarControlEvents, &EnvDTE::LIBID_EnvDTE, 8, 0> which I typedef to be CommandBarEvents. I managed to get the EnvDTE::Event:: CommandBarEvents object for each of the toolbar buttons by calling EnvDTE::Events::get_CommandBarEvents(), but when I try to call DispEventAdvise() on each of them, it doesnt work. It seems that DispEventAdvise() is only allowed to be called once in my addin, and calling it once per button just crashes the system. CComPtr<CommandBarControl> pCtrl; <Add the toolbar button and store it in pCtrl> CComPtr<EnvDTE::Events> pEvents; IDispatch* pDispHandler; IfFailGo(m_pDTE->get_Events(&pEvents)); IfFailGo(pEvents->get_CommandBarEvents(pCtrl, &pDispHandler)); CommandBarEvents::DispEventAdvise((IUnknown*)pDispHandler); I tried to find examples of how this is done but have had no luck so far. I would appreciate any help there. > Hi, > [quoted text clipped - 18 lines] > > > > Thanks! I found a work around for this problem, posting it for others who run into the same issue. IDispEventImpl::DispEventAdvise purposedly permits only one connection through the use of a cookie. In order to listen to events of multiple buttons you would need to bypass this function. Use AtlAdvise() instead and managed the list of cookies in your own class (one cookie per button). In the OnClick event you would need to distinguish the buttons by a name or id, which you determined when you created the button (e.g. CommandBarButton::caption or CommandBarButton::tag). > Hi Carlos, > [quoted text clipped - 45 lines] > > > > > > Thanks!
