odbc parameter missing source column???

P: n/a
Hi group,

I have an app that accesses an Access DB. We are using odbc because this
app will probably be using other databases as well dependiing on the clients

Consider the following;

OdbcParameter prmID = new OdbcParameter("ID", OdbcType.Text);//ID column is
Primary Key
prmID.SourceColumn =
myStronglyTypedDataset.RecordsTable.IDColumn.Colum nName;// ds created using
drag/drop from Server explorer in vs2003
myDataAdapter.MissingMappingAction = MissingMappingAction.Ignore;//I use
this to get a less 'generic' error or else I get "Restricted Data Access
Violation" error from ODBC - Access driver ???
myDataAdapter.Update(myStronglyTypedDataset.Record sTable);

This gives me
My Access Database column is of Type Text(50)
myStronglyTypedDataset.RecordsTable.Rows[0] holds "asdf-ghjk-qwer-tyui";

For some reason I get a "Missing SourceColumn Mapping for 'ID'" error. I've
checked and double checked. My parameters' source column is set properly
inside my parameter and my table has valid data. Since this is ODBC i
thought maybe the mapping types didn't match Access's so I tried using
another type of ODBCTypeText, .Varchar, I even tried DBType.String but to no

Does anybody have any ideas of what might be causing this? Could it be an
Access 2000 problem? ODBC? Any help would be appreciated.
