UPDATE: The code example below works. I changed the connection string. That was the problem. For an alternative (non-ADO) solution, see Mike Wills's link in the comments.
I have a c# class that (if I ever get it working) runs a program written in RPG code on AS/400 - JD Edwards. I know next to nothing about AS/400 and/or JD Edwards.
I've got other classes in my (intranet) web app that connect to JD Edwards, running SQL queries and setting/getting data. All of these are using the IBM.Data.DB2.iSeries dll and are working great.
For this, I wrote a similar class using the aforementioned dll, but it wasn't working. I even read somewhere online that you can't run a program using this dll. I found that a little fishy, but on suggestion from my JD Edwards co-worker, I scrapped the class and re-wrote it using the adodb dll. No data need be returned from this program run. I just want the program to run.
Here is a dummified version of the class:
private void runJDEProgram() {
ADODB.Connection cn = new ADODB.Connection();
cn.ConnectionString = "Provider=ABABAB;Data Source=111.111.111";
ADODB.Command cmdDetail = new ADODB.Command();
cn.Open(); //has to be open before setting an active connection.
cmdDetail.ActiveConnection=cn;
cmdDetail.CommandType = ADODB.CommandTypeEnum.adCmdText;
cmdDetail.CommandText = "{{CALL BLAH.BLAH(?,?)}}";
cmdDetail.Prepared = true;
cmdDetail.Parameters.Append(cmdDetail.CreateParameter("P1", ADODB.DataTypeEnum.adChar, ADODB.ParameterDirectionEnum.adParamInput, 10, "BLAH123"));
cmdDetail.Parameters.Append(cmdDetail.CreateParameter("P2", ADODB.DataTypeEnum.adChar, ADODB.ParameterDirectionEnum.adParamInput, 10, "BLAH456"));
object dummy = Type.Missing; //otherwise, we couldn't get past this.
cmdDetail.Execute(out dummy, ref dummy, 0);
cn.Close();
}
Here's the error I get when it runs:
{"[Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified"}
Where am I screwing up? Thanks!
EDIT: The connection string works when querying the AS/400 to get/set data. Does it need to be modified for an operation like this, or for use with ADO?
