At my agency, we have two custom tools that read the gINT database and created graphics for plans. Both were customized to fit different department needs. Since beginning our migration to Open Roads Designer CONNECT Edition, we have learned that reading an Access Database from a 64 bit application while most users are using 32 bit office is problematic. Since these tools are intended to read a gINT file, it only seems logical to ask if there is a gINT SDK that could be used to talk to an Open Roads Designer MVBA project to replicate the operation of these earlier tools.
I reached out to the gINT development team to see if they had any suggestions regarding your questions. Here is the answer they provided.
The tools can use the 64 bit Access Database Engine (ACE) as long as it is a different Office version than the 32 bit ACE version.
There is not a gINT SDK.
