Get database version string.
If contain "Firebird" substring...

BCB sample code:

AnsiString __fastcall TeMeL_IBDatabase::GetServerVersion(void)
{
if (ServerVersion_.IsEmpty())
{
TIBDatabaseInfo * dbiX = NULL;

try
{
dbiX = new TIBDatabaseInfo(this);

dbiX->Database = this;

ServerVersion_ = dbiX->Version;
}
catch (Exception &E)
{
ShowMessage("Az adatbázis-server verzió adatainak kiolvasása
sikertelen\n\n" + E.Message);
}

delete dbiX;
}

return ServerVersion_;
}
//---------------------------------------------------------------------------

bool __fastcall TeMeL_IBDatabase::isFirebirdServer(void)
{
int iPos = UpperCase(ServerVersion).Pos("FIREBIRD");

return (iPos > 0);
}
//---------------------------------------------------------------------------
