MDG_Merge enables the Add-In to jointly handle changes to both the model branch and the code project that the model branch is connected to. This event should be called whenever the user has asked to merge their model branch with its connected code project, or whenever the user has established a new connection to a code project. The purpose of this event is to enable the Add-In to interact with the user to perform a merge between the model branch and the connected project. Also look at MDG_Connect, MDG_PreMerge and MDG_PostMerge. Merge A merge consists of three major operations: - Export: Where newly created model objects are exported into code and made available to the code project. - Import: Where newly created code objects, Classes and such things are imported into the model. - Synchronize: Where objects available both to the model and in code are jointly updated to reflect changes made in either the model, code project or both. - Synchronize Type The Synchronize operation can take place in one of four different ways. Each of these ways corresponds to a value returned by SynchType: - None: (SynchType = 0) No synchronization is to be performed - Forward: (SynchType = 1) Forward synchronization, between the model branch and the code project is to occur - Reverse: (SynchType = 2) Reverse synchronization, between the code project and the model branch is to occur - Both: (SynchType = 3) Reverse, then Forward synchronization's are to occur. Object ID Format Each of the Object IDs listed in the string arrays described above should be composed in the following format: (@namespace)*(#class)*($attribute|%operation|:property)*
