Remarks

This method works with a project and embedded libraries: project settings, symbol libraries and the function libraries. If the project is read-only for example it is stored on a read-only drive) or number of logical pages exceeds number of licensed logical pages the project hierarchy will be opened read-only. Otherwise the project will be open read-write or exclusive, depending on available multi-user licenses. The embedded libraries always are opened read-only. Projects created by older EPLAN versions can be upgraded automatically. In case of backed-up projects please use Eplan.EplApi.HEServices.Restore class. The open mode will only be the wanted one when its possible to open the project in this mode. The Open Mode can be tested with the function Project.IsReadOnly and Project.IsExclusive after opening.
