Notice the first line, which is generated by the new DBDemo.SetAge method. It contains Fred's original age obtained from the stored procedure return value, as well as his sex, which was specified as an OUTPUT parameter. The process of creating, adding, and accessing parameters is a little long-winded when working with the generic interfaces. Both the SQL and OLE Data Provider implementations provide typed convenience methods that simplify parameter management at the cost of code portability. To demonstrate this, we can cast sqlCon to an instance of SqlConnection (because DBDemo is built using the SQL Server Data Provider) and replace the SetAge method with the following implementation:

using using using using using System; System.Data; System.Data.SqlClient; System.Data.SqlTypes; Microsoft.SqlServer.Server;

If, for some reason, you really don t want the C# compiler to reference the MSCorLib .dll assembly, you can use the /nostdlib switch . Microsoft uses this switch when building the MSCorLib .dll assembly itself . For example, the following command line will generate an error when CSC .exe attempts to compile the Program .cs file because the System.Console type is defined in MSCorLib .dll:

You ve now assigned a fixed maximum value of 1,400 to the primary vertical axis . As a result, the static data series for which you defined this same value on the Basis 1 worksheet now appears at the top of the plot area . You now want to turn this line into an area that fills the part of the plot area that corresponds to the campaign period of the project (i .e ., calendar weeks 21 to 26) with a specific color . Because the marking of this data series is a little more complex than in other cases, I ll describe the procedure in detail here: 1. Select the Chart Tools/Layout tab in the Ribbon, click the drop-down arrow in the Current Selection group, and select the Series Campaign entry . This data series is then selected . 2. Now open the Chart Tools/Design tab, and click the Change Chart Type button in the Type group . 3. In the dialog box that opens, (see Figure 2-40), select Column as the chart type and select the first chart sub-type shown Clustered Column as the chart type of the series . Click OK to convert the line into columns . 4. Select the columns generated, and open the Format Data Series dialog box again . Select Series Options, and move the slider for the Gap Width setting all the way to the No Gap position on the far left . This corresponds to a gap width of 0 percent, which you also could have entered in the field provided . This brings all the columns together in one area .

In this example, setting temp to null is legal because T is known to be a reference type, and all reference type variables can be set to null . If T were unconstrained, the code above would not compile because T could be a value type, and value type variables cannot be set to null . The struct constraint promises the compiler that a specified type argument will be a value type . Any value type, including enumerations, satisfies this constraint . However, the compiler and the CLR treat any System.Nullable<T> value type as a special type, and nullable types do not satisfy this constraint . The reason is because the Nullable<T> type constrains its type parameter to struct, and the CLR wants to prohibit a recursive type such

would update all of T1's rows, adding to c1 the maximum c1 value from T1 when the update started. You shouldn't be concerned that the maximum c1 value would keep changing as the operation proceeds because the operation occurs all at once.

One of the Descriptions was truncated. You need to check all the Excel descriptions to make sure they re 255 characters or less. You can use Excel s LEN function to identify the descriptions that are too long. There s a third problem that SharePoint didn t notify us about. The Issue Date column has a default setting of Today s Date. When the data was pasted, SharePoint used the default, not the date from the Excel list. For now, you need to change the default setting for the Issue Date column to None. After you ve pasted the data from Excel, you can change the default back to Today s Date. After fixing these issues, copy and paste the Tasks data again.

Number of unique operators (n1) Number of unique operands (n2) Total occurrences of operators (N1) Total occurrences of operands (N2) These measurements are used to derive a set of complexity metrics. For example, a measure of code length is determined by adding N1 and N2. Halstead metrics also can calculate a Difficulty metric with the following formula: (n1 / 2) * (N2 / n2). In the following code sample, there are six unique operators and four unique operands, used a total of 6 and 12 times each, respectively. Table 7-2 shows how I calculated these counts.
