Others have stated that OleDb required a ? and that it did not accept Named Parameters. This is false. I have fixed my code and it is working. The problem at hand was that the Statement required different ways to define spaces.
With the OleDB connection the Table Name if it had a space had to be in EITHER `(Ticks) or both will work the same.
The confusions begins when you have Column Names with spaces. When the statement is built All column names have to have an _ (Under Score) in place of the Spaces the column names. While both `(Ticks) and are optional for Column names. All that is REQUIRED is the replacement of " "(Space) with _(under score)
What adds to the confusion is the fact that the table name is REQUIRED to have either `(Ticks) or and if you do replace a " "(Space) with _(under score) it will not find the table.
My fixed Code:
string SelectOleDb = "SELECT Top 1 * From [Employee Info] Where Employee_Name= @EmployeeName Order By ID DESC";
OleDbConnection OleDbCon = new OleDbConnection(EmployeeInfo.Properties.Settings.Default.cstrEmployeeInfoDatabase);
OleDbDataAdapter OleDbAdpt = new OleDbDataAdapter();
OleDbCommand OleDbCom = new OleDbCommand(SelectOleDb, OleDbCon);
OleDbCom.Parameters.AddWithValue("@EmployeeName", employee_NameComboBox.Text);
OleDbAdpt.SelectCommand = OleDbCom;
DataSet EmployeeInfoDS = new DataSet();
OleDbCon.Open();
OleDbAdpt.Fill(EmployeeInfoDS);
OleDbCon.Close();
OleDbCon.Dispose();
DataTable EmployeeInfoDT = EmployeeInfoDS.Tables[0];
