I trying to connect MAS90 pvx or ProvideX driver.. ---------------------------------------------------------------------- dseligo · 2022-12-23 21:16 Can you put some dots (full stops, '.') in your post? It's very hard to understand what is your problem. ---------------------------------------------------------------------- eldonfsr · 2022-12-23 23:07 k sorry here message when run the app or active sql... ---------------------------------------------------------------------- LacaK · 2023-01-03 09:53 It seems, that your ODBC driver does not implement transaction support. It is problem. IMO it is not related to 32/64 bits. (32bit application should use 32bit ODBC which should use 32 bit ODBC driver ...)
