Norman Rorke | Is there any way to retrieve the version of a recompiled DBSRVR executable?
I need this to determine whether the server I'm talking to has the required remote procedure code before I attempt to call or register the procedure. It seems DBISAM allows a client application (e.g. DBSYS) to register a remote procedure and it's users even when the server does not contain the procedure code. This being the case, it seems the tidiest way to do this is to interrogate the DBSRVR version number or some kind of user-defined variable. I have temporarily resolved by embedding the version number is the ServerEngine.ServerDescription variable of the server which is a bit clumsy. |

Tim Young Elevate Software www.elevatesoft.com Hi Tim, Thanks for responding. Unfortunately GetRemoteEngineVersion returns the Engine version. What I am after is the version of the server executable. Whenever I add new code to the server I bump the project version up before recompiling. If I could check the exe version from within a client application I would be able to tell whether the server contains a given procedure. I assume this is not possible so I'll continue resolving by appending the version no to the Server Description which my client applications can interrogate. By the way, this is a prefect candidate for remote user-defined variables that could be read by client applications. Any chance of adding something like that in ElevateDB? |

Of course! That should be the very first server procedure to implement. Thanks Tim |
