Message:

RemoteSession.cs Interface: Added:

  • Lock method to lock glvns on M db.
  • Encoding ConnectionEncoding to set the connection encoding on the DB

BMXNetSessionConnection: Added:

  • Abstract ConnectionEncoding property
  • Clarified error message that gets called. It now says that you don't have TransmitRPC writer lock??? When the error could be any BMXNetException.

BMXNetSessionSocketConnection:

  • Added ConnectionEncoding property
  • ReceiveString completely refactored: now we get much better performance
  • Timers and Debug Writes are all over the place now.

BMXNetRemoteSession:

  • Implemented the 2 new 'stuff' in Interface RemoteSesssion: -- Lock glvn -- Encoding Property
  • TableFromSQL with Dataset has an honest to god bug in it: The passed dataset and table name are not used even though they are passed.

BMXNetSessionConnectionOverAnotherSessionConnection:

  • Implemented the Encoding Property in Interface RemoteSession to have the project compile.

Updated dlls. Have fun.
