You can store order status strings in any number of places. One option is to store them in the database, perhaps in a table called Status. You could then link to the Orders table by matching the existing Orders.Status field to, say, Status.StatusID. However, it s reasonable to regard status information as static. Although the Orders table is capable of containing any integer for an order status, the CommerceLib code uses order status information in a more formal way. The statuses that exist, in fact, are a consequence of the qr code reader

Notice the if condition for radioButton3. Because we have not made any changes to the DataSet as such, the code deliberately marks each row as modified. This is done by using the SetModified() method of the DataRow class. This way, we will be able to see how the DiffGram format stores old and new values. Finally, the saved XML file is opened in a browser by using the Start() method of the Process class. Figure 7-7 shows a sample run of the application without saving any schema information. Similarly, Figures 7-8 and 7-9 show the output XML file with schema information and DiffGram, respectively. Notice how the schema information is emitted in Figure 7-8. Also, examine Figure 7-9 carefully. This XML output is in DiffGram format. See how the <diffgr:before> section stores the original values of the DataRows, whereas the current values are displayed at the top.

pipeline structure we ve chosen, which is independent of the database. For this reason, you should include status information in your code. You could store human-readable status strings in web.config, in an external resource file (useful for multilingual sites), or anywhere else you choose. In this chapter, you ll put this information in a static read-only string array in the CommerceLibAccess class, where you can access it from wherever you choose. The indexes of the entries in the array match the status values that are used in your order pipeline. Add the following member to the CommerceLibAccess class, in CommerceLibAccess.cs: public class CommerceLibAccess { public static readonly string[] OrderStatuses = {"Order placed, notifying customer", // 0 "Awaiting confirmation of funds", // 1 "Notifying supplier stock check", // 2 "Awaiting stock confirmation", // 3 "Awaiting credit card payment", // 4 "Notifying supplier shipping", // 5 "Awaiting shipment confirmation", // 6 "Sending final notification", // 7 "Order completed", // 8 "Order canceled"}; // 9 ... Note the one new status here Order canceled, with a value of 9 for when you want to cancel a customer order. For the purposes of data binding to the CommerceLibOrderInfo class, you also provide a new public property to expose order statuses as strings. Add the following members to CommerceLibOrderInfo: public string StatusAsString { get { try { return CommerceLibAccess.OrderStatuses[Status]; } catch { return "Status unknown"; } } } public string CustomerName { qr code scanner

The WriteXml() method writes data and optionally XSD schema information. What if you need to extract only the schema information and not the data itself The WriteXmlSchema() method does that job by writing only the schema of the DataSet and not the data. To illustrate the use of WriteXmlSchema(), you can modify the preceding application to include an additional radio button. The new interface of the application is shown in Figure 7-10.

You ll expose audit trail data via this new class, which is very similar to (although simpler than) the CommerceLibOrderInfo and CommerceLibOrderDetailInfo classes added earlier. As with these classes, you can add CommerceLibAuditInfo to the CommerceLibAccess.cs file: /// <summary> /// Wraps audit trail data /// </summary> public class CommerceLibAuditInfo { public int AuditID { get; private set; } public int OrderID { get; private set; } public DateTime DateStamp { get; private set; } public string Message { get; private set; } public int MessageNumber { get; private set; } public CommerceLibAuditInfo(DataRow auditRow) { AuditID = (int)auditRow["AuditID"]; OrderID = (int)auditRow["OrderID"]; DateStamp = (DateTime)auditRow["DateStamp"]; Message = auditRow["Message"] as string; MessageNumber = (int)auditRow["messageNumber"]; } }
