# re: Data Access Application Block 3.1

Hi,
I was using the DAAB 3.1 with Oracle and the place where i couldn't use it to the max is the Oracle Parameter. In the Oracle class you have a method declared as ..

protected override IDataParameter[] GetDataParameters(int size)
{
return new OracleParameter[size];
}

as this is protected so i can't call it in program and i want to use arrays of parameters for integrity or parameters and readability. Since this function is not being used in the class itself so i think there is no reason to keep it protected.

i wish to use it the same way as we use SqlParameter[] or OracleParameter[] array of objects.


AdoHelper helper = GetAdoHelper("Oracle");
string cs = GetConnectionString("Oracle");
string SQLStr = "CBS_TASK_DETAILS.GET_TASK_DETAILS ";

System.Data.IDataParameter[] oraParams = helper.GetDataParameters(8) ;


oraParams[0] = helper.GetParameter("TaskRid",VarChar,13);
oraParams[0].Direction = ParameterDirection.Input;

oraParams[0].Value = this.DropDownTaskRid.Text;


oraParams[1] = helper.GetParameter("OrgDetails",VarChar,650);
oraParams[1].Direction = ParameterDirection.Output;

..blah blah ..

Regards

To me, DAAB 3.X was a downgrade from 2.X. The documentation is poor; the installation for On-line Help fails and the CHM is just an NNCode (or such) dump. All the other Application Blocks have documentation on the archtecture and how to appropriately use the AB. This does not, and makes it almost worthless as I have to now invest time in digging into the code to figure out how it works to be able to leverage it. The point of ABs, or other similiar code, is to avoid having to go to the code level to figure out what the point of the code is. I don't delve into the code of .NET itself just to put together a simple form.

Along with the documentation being poor, the sample applications are beyond poor. These things should not even have been included as they make so little use of the DAAB that they are utterly and completely useless. 10/5/2004 12:02 PM | Hollywood

I saw on the gotdotnet DAAB workspace that users are being redirected to the Enterprise Library. Is the Enterprise Library version the true successor to the DAAB 3.1, or has it been substantially modified by MS. I'd love an opinion from a former developer.

Thanks,

One of the things I worked on for 3.1 was the documentation. You might like it better now. 4/27/2005 1:28 PM | Chris J. Breisch

To be honest, I haven't yet made up my mind about the EL. I know that MS is really pushing it as the successor to the application blocks, but I have some serious concerns with its architecture and the architecture of the development effort.

However, I have no intentions at the current time of updating the DAAB to Whidbey, and EL V2 "should" work with Whidbey, so that may become your overriding concern at some point. 4/27/2005 1:30 PM | Chris J. Breisch

Hi

I would be great if you could say something about the Event Log Error, handling in Data Access Application Block???????? 7/14/2005 5:29 AM | Irfan

Hi ,

I was wondering about the DAAB v2.x and v3.x. It uses the app.config file to dictate which database it connects to - I'm using the DAAB for my windows application - and I want to be able to connect to a few different database, Live / Testing / Development.

I have been looking everywhere and can't solve this problem.
