My program creates columns at runtime with the following code:

Code:
    Cmd = New OleDb.OleDbCommand("ALTER TABLE [Parent] ADD [" & ColumnDate & "] int", con)
    objCmd = New OleDb.OleDbCommand("ALTER TABLE [Parent] ADD [" & ColumnDate & "] int", con)
    objCmd.ExecuteNonQuery()
I add data into the newly inserted column with the following code:

Code:
 da.SelectCommand = New OleDb.OleDbCommand(sql, con)
    Dim cb As New OleDb.OleDbCommandBuilder(da)
    cb.QuotePrefix = "["
    cb.QuoteSuffix = "]"
    ds.Tables("SchoolMaticsDatabase").Rows(inc).Item(ColumnDate) = Hours * Num
    da.Update(ds, "SchoolMaticsDatabase")
All of the above works fine; the issue arises when I try to edit the information originally placed in the newly added column. These are the approaches that I have taken. (None of them give an error message; it simply won't update within the database.)

Approach 1:

Code:
da.SelectCommand = New OleDb.OleDbCommand(sql, con)
    Dim cb As New OleDb.OleDbCommandBuilder(da)
    cb.QuotePrefix = "["
    cb.QuoteSuffix = "]"

    For Each column As DataColumn In ds.Tables("SchoolMaticsDatabase").Columns
        If IsDate(column.ColumnName) = True Then
           ds.Tables("SchoolMaticsDatabase").Rows(inc).Item(column.ColumnName) = DataGridView3.Item(column.ColumnName, 0).Value
        End If
    Next
    da.Update(ds, "SchoolMaticsDatabase")
Approach 2:

Code:
da.SelectCommand = New OleDb.OleDbCommand(sql, con)
    Dim cb As New OleDb.OleDbCommandBuilder(da)
    cb.QuotePrefix = "["
    cb.QuoteSuffix = "]"
    For count = 13 To MaxColumns - 1
        ds.Tables("SchoolMaticsDatabase").Rows(inc).Item(count) = DataGridView3.Item(count, 0).Value
    Next
    da.Update(ds, "SchoolMaticsDatabase")
Approach 3:

Code:
  For Each column As DataColumn In ds.Tables("SchoolMaticsDatabase").Columns
        If IsDate(column.ColumnName) Then
           Cmd = New OleDb.OleDbCommand("UPDATE [Parent] SET [" & column.ColumnName & "]=" & DataGridView3.Item(column.ColumnName, 0).Value & " WHERE [ID]=" & inc + 1, con)
           objCmd = New OleDb.OleDbCommand("UPDATE [Parent] SET [" & column.ColumnName & "]=" & DataGridView3.Item(column.ColumnName, 0).Value & " WHERE [ID]=" & inc + 1, con)
           objCmd.ExecuteNonQuery()
         End If
    Next
I added a column to the table manually via opening the access database and all the above approaches work for editing data stored in that column. So I believe it is something to do with the fact that the columns are created at run time.
