Details

MDG_Connect enables the Add-In to handle a user driven request to connect a model branch to an external application. This function is called when the user attempts to connect a particular Enterprise Architect package to an as yet unspecified external project. This event enables the Add-In to interact with the user to specify such a project.

The Add-In is responsible for retaining the connection details, which should be stored on a per-user or per-workstation basis. That is, users who share a common Enterprise Architect model over a network should be able to connect and disconnect to external projects independently of one another.

The Add-In should therefore not store connection details in an Enterprise Architect repository. A suitable place to store such details would be:

 

SHGetFolderPath(..CSIDL_APPDATA..)\AddinName

 

The PackageGuid parameter is the same identifier as is required for most events relating to the MDG Add-In. Therefore it is recommended that the connection details be indexed using the PackageGuid value.

The PackageID parameter is provided to aid fast retrieval of package details from Enterprise Architect, should this be required.
