NET Framework makes sharing classes between a NET Remoting server and a Web service straightforward However, because of the inheritance difference just mentioned, you can't have the Web service and the NET Remoting server descend from the same base class of functionality The NET Framework, in fact, does not permit inheritance from multiple classes We'll start by writing a helper class that constitutes the programming interface for both the NET Remoting server in this chapter and the Web service we'll create in 13 The remote service is actually a class built around the Northwind database that lets you obtain gross sales information on a per-year basis A nice feature of this service is that it lets you obtain information in two ways: as raw tabular data to format and analyze or as a ready-to-print, snazzy bar chart.

Writing the Data Provider Class Because our final goal is exposing a common set of functionalities through both the NET Remoting server and the Web service interfaces, let's group all the needed core code into a separate middle-tier class that both higher-level layers can easily call We'll call this helper class SalesDataProvider and bury into its code all the details about connection strings, SQL commands, and bar chart creation The class outline is shown here: namespace XmlNetCS { public class SalesDataProvider { // Constructor(s) public SalesDataProvider() {..} // Internal properties 432.

One key issue I want to point out in the file format is that I store the binary files' load address in the SWS file Originally I stored only the addresses for the functions, but I remembered the case in which the binary might be relocated in memory In that situation, the SWSDLLDLL run time would be called with one address, but I wouldn't have any record of that address in any of the module's loaded SWS files Even though we should always rebase our DLLs, sometimes we forget, and I wanted to make sure SWS didn't crater when that happened One area that did give me a little trouble was generating the symbols for the initial SWS module Because of the way programs are linked and symbols are generated, many of the symbols reported in a module are not those that have _penter calls inserted in them.

private string "DATABASE=northwind;SERVER=...;UID=sa;"; private int m_Year = 0;

For example, if you link against the static C run time, your module will have all sorts of C runtime functions added Since the address lookup would be faster in the SWS run time if there were fewer symbols, I looked at a few ways to minimize the numbers Listing 19-3 shows the symbol enumeration callback and how I started limiting the number of symbols The first step I took was to check whether the symbol had corresponding line information with it Because I assumed that functions that have _penter calls were properly compiled using the steps I specified earlier, I safely got rid of many extraneous symbols My next step in eliminating symbols was to check whether specific strings are part of the symbols For example, any symbols that start with _imp__ are imported functions from other DLLs.

There are two other checks that I didn't implement but instead left as exercises for you dear readers The first is that you should be able to flag symbols from specific files, which SWS should ignore The main reason for implementing this feature is so that you can add all the C run-time source files to that list The last symbol elimination trick ensures that the address in question comes only from a code section in the module You might not need this last check, but it would ensure that only true code symbols are used Listing 19-3: SWS symbol enumeration 686.

Table 6-4 for the CountC function reveals that each independent true and false outcome for each conditional clause is executed at least one time. But as we execute the basis path tests and systematically traverse each linear independent path we soon realize there are two separate errors in this simple function. The first error is detected with basis path test 3. The expected output is 0, but in fact it will be 1. The second error is found with basis path test 4, for which the expected output is 1, but the return value is actually 0. Table 6-4: Truth Table for CountC Function Open table as spreadsheet

public string GetSalesReportBarChart(int theYear) {...} // INTERNAL METHODS // Fetch the data private DataTable ExecuteQuery(int theYear) {...} // Draw the bar chart based on the data in the specified table private string CreateBarChart(DataTable dt) {...} // Encode the specified bitmap object as BinHex XML private string SaveBitmapAsEncodedXml(Bitmap bmp) } } The class contains only a couple of public methods GetSalesReport and GetSalesReportBarChart. These methods will also form the public interface of the .NET Remoting server we'll build in this chapter and the Web service slated for 13. Implementation Details GetSalesReport takes an integer that indicates the year to consider and returns a DataTable object with two columns one containing employee last names and one showing total sales for the year for each employee. The method runs the following SQL query against the Northwind database: SELECT e.lastname AS Employee, SUM(price) AS Sales FROM (SELECT o.employeeid, SUM(od.quantity*od.unitprice) AS price FROM Orders o, [Order Details] od WHERE Year(o.orderdate)=@TheYear AND od.orderid=o.orderid GROUP BY o.employeeid, od.orderid )AS t1 INNER JOIN Employees e ON t1.employeeid=e.employeeid GROUP BY t1.employeeid, e.lastname 433 od.orderid,

Table 3-1: ASPTraceListener Output and Control Properties Property ShowDebugLog ShowOutputDebugString EventSource Default Value true false null/Nothing Description Shows output in any attached debugger Shows output through OutputDebugString The name of the event source for writing output to the event log. No permissions or security checking for access to the event log is done inside BugslayerUtil.NET.DLL. You'll need to request permissions before setting the EventSource. The TextWriter object for writing output to a file If a debugger is attached, the debugger stops immediately when an assertion triggers.

All the main work for doing the assertion output, which includes finding the assertion controls on the page, is done by the ASPTraceListenerHandleOutput method, shown in Listing 3-4 My first attempt at writing the HandleOutput method was much more involved Although I could get the current IHttpHandler for the current HTTP request from the static HttpContextCurrentHandler property, I couldn't find a way to determine whether the handler was an actual SystemWebUIPage If I could figure out that it was a page, I could easily grind through and find any assertion controls on the page My original attempt was to write quite a bit of code by using the very cool reflection interfaces so that I could walk the derivation chains myself.

The query involves three tables Employees, Orders, and Order Details and basically calculates the total amount of each order issued in the specified year by a particular employee Finally, the amounts of all orders are summed and returned together with the employee's last name GetSalesReportBarChart works in two steps: first it gets the sales data by calling GetSalesReport, and then it uses this information to create the bar chart The bar chart is generated as an in-memory bitmap object and is drawn using the GDI+ classes in the SystemDrawing namespace To make the image easily transportable over the wire for NET Remoting clients as well as for Web service clients, the GetSalesReportBarChart method converts the bitmap to JPEG, encodes the bits as BinHex, and puts the results in an XML string.
