Without /clr at all, of course, you are compiling native C++ in the classic way. If you try to use any of the C++/CLI language features, you will get compiler errors.

you would find this error in your log file for each input record Record 1: Rejected - Error on table DEPT, column ENTIRE_LINE. Column not found before end of logical record (use TRAILING NULLCOLS) Here, SQLLDR is telling you that it ran out of data in the record before it ran out of columns. The solution is easy in this case, and in fact SQLLDR even tells us what to do: use TRAILING NULLCOLS. This will have SQLLDR bind a NULL value in for that column if no data exists in the input record. In this case, adding TRAILING NULLCOLS will cause the bind variable :ENTIRE_LINE to be NULL. So, you retry with this control file: LOAD DATA INFILE * INTO TABLE DEPT REPLACE FIELDS TERMINATED BY "," TRAILING NULLCOLS (DEPTNO, DNAME "upper(:dname)", LOC "upper(:loc)", LAST_UPDATED date "dd/mm/yyyy", ENTIRE_LINE ":deptno||:dname||:loc||:last_updated" ) BEGINDATA 10,Sales,Virginia,1/5/2000 20,Accounting,Virginia,21/6/1999 30,Consulting,Virginia,5/1/2000 40,Finance,Virginia,15/3/2001 Now the data in the table is as follows: ops$tkyte@ORA11GR2> select * from dept; DEPTNO -----10 20 30 40 DNAME -------------SALES ACCOUNTING CONSULTING FINANCE LOC ------------VIRGINIA VIRGINIA VIRGINIA VIRGINIA ENTIRE_LINE ----------------------------10SalesVirginia1/5/2000 20AccountingVirginia21/6/1999 30ConsultingVirginia5/1/2000 40FinanceVirginia15/3/2001 LAST_UPDA --------01-MAY-00 21-JUN-99 05-JAN-00 15-MAR-01

There are two ways you can include the Bing Maps control assemblies to the solution. One is making them part of the dlr.xap file (for that you need to update the AppManifest.xaml file), and the second approach is to create a separate ZIP file and reference it from the hosting HTML file. This section will describe both approaches, however, the second approach is recommended to make the application more flexible and modular.

Diagnostic directives produce user-defined compile-time warning and error messages. The following is the syntax of the diagnostic directives. The messages are strings, but notice that unlike normal C# strings, they do not have to be enclosed in quotation marks. #warning Message #error Message When the compiler reaches a diagnostic directive, it writes out the associated message. The diagnostic directive messages are listed by the compiler along with any compilergenerated warning and error messages. For example, the following code shows an #error directive and a #warning directive. The #error directive is inside an #if construct, so that it will be generated only if the conditions on the #if directive are met. The #warning directive is a reminder to the programmer to come back and clean up a section of code. #define RightHanded #define LeftHanded #if RightHanded && LeftHanded #error Can't build for both RightHanded and LeftHanded #endif #warning Remember to come back and clean up this code!

As mentioned, we must add the keyword public at the class level to make this type visible in another assembly (see Listing 3-5). Listing 3-5. Using Our Trivial Class from Another Assembly // file2.cpp #using "file1.dll" // We'll define a function, so we can see it in the metadata later. void F() { R r; } int main() {} Without the keyword public, the type R will not be visible to the code in file2.cpp. Compile file2.cpp with the usual options for managed code (just /clr or /clr:pure will do) to generate an executable assembly file2.exe.

First, you can choose to keep state on the web server. This is easily accomplished through the use of the ASP.NET Session object, which is a name/value collection of arbitrary data or objects. ASP .NET manages the Session object, ensuring that each user has a unique Session, and that the Session object is available to all Web Forms code on any page request. This is by far the easiest way to program web applications. The Session object acts as a global repository for almost any data that you need to keep from page to page. By storing state data on the web server, you enable the type of host-based computing that has been done on mainframes and minicomputers for decades. As I ve already expressed, however, there are drawbacks. Session is a global repository for each user, but as any experienced programmer knows, the use of global fields is very dangerous and can rapidly lead to code that s hard to maintain. If you choose to use Session to store state, you must be disciplined in its use to avoid these problems. The use of Session also has scalability and fault tolerance ramifications.
