Hello,

The TCRSQLConnection component is needed to overcome restrictions of dbExpress on Delphi versions earlier than RAD Studio 2007. As you are using C++Builder XE, you don't have to compile anything. You can use our dbExpress driver for InterBase & Firebird in the same way as the standard dbExpress drivers supplied by Borland. For additional information, please refer to the description of the TSQLConnection component in the help. To setup SQLConnection in order to use dbExpress driver for InterBase & Firebird, you should set the TSQLConnection.ConnectionName property to "Devart InterBase" in design-time.

Thanks, now I understand. I loaded up the driver like this...

Code: Select all
      dbObj->Params->Clear();
      dbObj->Params->Add("Database="+database);
      dbObj->Params->Add("User_Name="+username);
      dbObj->Params->Add("Password="+password);
      dbObj->LibraryName = "dbexpida40.dll";
      dbObj->GetDriverFunc = "getSQLDriverInterBase";
      dbObj->Open() ;


but I am still getting the same errors i was getting with regular dbexpress which is ...

Project [project name.exe] raised exception class TDBXError with message 'DBX Error: Driver could not be properly initialized. Client Library may be missing, not installed properly, of the wrong version, or the driver may be missing from the system path.


I do have the driver in the folder with my exe and I am using cBuilder XE with interbase 6.
This did originally work with interbase XE but not interbase 6 but now it doesnt work with either. Any ideas?[/code]

I managed to get it to work now. Had to restart XE to refresh the INI for dbexpress and add the include path.

Now I am getting

Project [projectname.exe] raused exception class EIBCError with message ' I/O error for file "c:\proj\debug\win32\DATABASE NAME" Error while trying to open file the system cannot find file specified '.

This error means the following: the database you have set in the TSQLConnection.Params.DataBase parameter does not exist. Please check that you are using the correct path to your database.

Do i need to specify the db name any differently than the regular TSQLConnection param?

dbObj->Params->Add("Database="+database);

This works with the regular DBX drive but once i move back to the devart one i start getting that error.

You should use the following code:
Code: Select all
dbObj->Params->Values["Database"] = database;
