I thought that's what they were... Isn't that how you define properties? "public [type] [name]"?

No. Those are global variables. Click on Help in VS2005 and then click "index". Enter "properties"... Or start with this direct local link:

I found that. (BTW, that's just another plus of the IDE - the F1 help is really helpful!)

The "set" method inserts a Pic x(5) return code into the start of an interface block, defined as a COBOL structure of 8192 bytes (this is for compatibility with COM BSTRING type.)
Why did you use char.Parse("0") instead of just '0'?

Because '0' wouldn't work...? :-)

Must be that managed vs. unmanaged stuff... I can assign '0' to a char variable. I believe you - I wonder what the difference is?

Excellent! It will take a little time. It is a journey of many small steps... Each method you write will be "better" than the last one.

OK - here's what I've got for one of the methods. I'm not sure that this looks right...

protected DataSet itemInfo = new DataSet();
....
// Establish the element for this class instance
public void retrieveElementInfo(String reiElementId)
{
// Retrieve the information about the passed program
String sql = "SELECT * "
+ "FROM active_elements "
+ "WHERE element_id = '" + reiElementId.Trim() + "'";
SqlDataAdapter da = new SqlDataAdapter(sql, dbConn);
da.Fill(itemInfo);

if (itemInfo.Tables.Count > 0)
{
elementType = itemInfo.Tables[0].Rows[0]["element_type"].ToString().ToCharArray()[0];
elementSubType = itemInfo.Tables[0].Rows[0]["element_subtype"].ToString().Trim();
fileName = itemInfo.Tables[0].Rows[0]["server_name"].ToString().Trim();
elementId = reiElementId.Trim();
}
}

(We have to trim the stuff coming out of the database because it's defined as char instead of varchar...)
