.NET Forum / Visual Studio.NET / Extensibility / September 2005How to get notified when configuration's properties change?
Hi, I'm wondering if there is any way to receive a notification when the user changes a property of a project configuration (e.g. she changes the set of conditional compilation constants in C# projects). I've explored related VSIP interfaces thoroughly, but didn't find anything. Any ideas will be appreciated. Thanks in advance.

Thanks for your understanding!

Hi Dmitry, I just realized that the properties like the "conditional compilation contants" are actually configuration specific. So they are actually contained in a different collection of the Configuration object. You're right though, I couldn't find a way to detect a change notification here either. I'll dig through the implementation in a bit and see if we're even raising a property change notification, and get back to you on this shortly. Sincerely, Ed Dore [MSFT] This post is 'AS IS' with no warranties, and confers no rights. Hi Dmitry, When the contents of the edit control for that "Conditional compilation constants" property changes, we end up setting an internal state flag that ultimately is used to determine if the underlying property needs to be updated or changed. There is no event processing or change notifications getting fired on either this flag, or when the property itself gets modified. Ultimately, all this cumulates in a call to COleDispatchDriver::PutProperty in ATLCOM.H, and that doesn't fire any kind sort of event like an IPropertyNotifySink or anything. So I think we're out of luck there. One alternative though, that might potentially work would be to listen for RDT events by implementing IVsRunningDocTableEvents3. You could check the property for changes when the OnAfterAttributeChange or OnAfterAttributeChangeEx event is called with VSRDTATTRIB.RDTA_DocDataIsDirty flag on a particular proj file. When you change the project properties, the proj file is flagged as being dirty, so you might be able to use this event to determine when the proj file settings are modified, and then manually check the property for changes. I haven't tested this, but I'm guessing that this might actually be a valid option in this scenario. Sincerely, Ed Dore [MSFT] This post is 'AS IS' with no warranties and confers no rights. Hello Ed, thank you a lot for your help! I've checked, and OnAfterAttributeChange really seems to be a viable approach. Bet on I would not find it myself :) Regards, Dmitry Shaporenkov JetBrains, Inc http://www.jetbrains.com "Develop with pleasure!" > Hi Dmitry, > [quoted text clipped - 22 lines] > Ed Dore [MSFT] > This post is 'AS IS' with no warranties and confers no rights.
