I am testing DBX drivers for interbase and Firebird because the standard DBX4 drivers cause memory leak when i use the following instructions in a loop (very simple program) :
sqlconnection.open;
sqlconnection.close;

With upscene drivers there is no leak (or very little memory leak).
With devart drivers (trial version), the leak is very big.

I would like to use Devart drivers because i use both Interbase and firebird but the memory leak block my decision.

Best regards

This memory leak is caused by reloading the driver DLL each time you reconnect. You can avoid the leak and increase connection performance by preloading the driver DLL:

Code: Select all

var
  LibHandle: THandle;

initialization
  LibHandle := LoadLibrary('dbexpida40.dll');

finalization
  FreeLibrary(LibHandle);
