Hi Bill. My code is below:

 OleDbCommand oCommX = new OleDbCommand();
 string oConnX = @"Provider=VFPOLEDB.1; Data Source=" + @"C:\DISA\DIS2012";
 string oSelX = "Select AAP_TITLE from DFAAP WHERE AAP_DATEBR >= ? ";
 DateTime dtX = DateTime.Now;
 oCommX.Parameters.Add(new OleDbParameter("?MyDate ", dtX));
OleDbDataAdapter oDaX = new OleDbDataAdapter(oSelX, oConnX);
DataSet oDsX = new DataSet();
oDaX.Fill(oDsX);

If I Change the where clause to 1=1, rows are selected fine
The AAP_DATEBR is a Date Field in a DBF thats part of a .DBC
