Hello Zoltan
I don't think you can populate a ComboBox with the DBDataSource binded to it and I don't think that is the way you should use it.
If I'm right, what you want to do is populate a combobox from the OITM table, and I guess to save is as a foreign key in an other table.
I think you should use the following code,
  - it adds the DBDataSource OITM that wil allows you to populate the combo
  - it link the combobox to the table where you want to save the item code
  - It adds the valid value to the combo
oDBDSItemCode = oForm.DataSources.DBDataSources.Add("OITM") 
ocbItemCode.DataBind.SetBound(True, "name_of_the_table_you_want_to_save_the_data", "Foreign_key_field_name")
oDBDSItemCode.Query()
For x = 0 To oDBDSItemCode.size - 1
    ocbItemCode.ValidValues.Add(oDBDSItemCode.GetValue("ItemCode",i),oDBDSItemCode.GetValue("ItemName",i))
