Note If you plan on using Visual Studio 2005 AJAX-enabled web applications (following the web application model and not the ASP.NET web site model), be sure to install ASP.NET AJAX after installing Visual Studio 2005 SP1.

If you were to count the number of documented parameters you can set in each of the database versions 9i Release 2, 10g Release 2, 11g Release 1 and 11g Release 2 you d probably find 258, 259, 294, and 342 different parameters, respectively (I m sure there could be additional parameters available on an operating system specific basis). In other words, the number of parameters (and their names) varies by release. Most parameters, like db_block_size, are very long-lived (they won t go away from release to release), but over time many other parameters become obsolete as implementations change. For example, in Oracle 9.0.1 and before back to version 6 of Oracle there was a distributed_transactions parameter that could be set to some positive integer and that controlled the number of concurrent distributed transactions the database could perform. It was available in prior releases, but it is not found in any release subsequent to 9.0.1. In fact, attempting to use that parameter with subsequent releases raises an error. For example: ops$tkyte%ORA11GR2> alter system set distributed_transactions = 10; alter system set distributed_transactions = 10 * ERROR at line 1: ORA-25138: DISTRIBUTED_TRANSACTIONS initialization parameter has been made obsolete

A statement is a source code instruction describing a type or telling the program to perform an action. A simple statement is terminated by a semicolon. For example, the following code is a sequence of two simple statements. The first statement defines an integer variable named var1 and initializes its value to 5. The second statement prints the value of variable var1 to a window on the screen. int var1 = 5; System.Console.WriteLine("The value of var1 is {0}", var1);

Some of the most important syntactic rules for preprocessor directives are the following: Preprocessor directives must be on lines separate from C# code. Unlike C# statements, preprocessor directives are not terminated with a semicolon. Every line containing a preprocessor directive must start with the # character. There can be space before the # character. There can be space between the # character and the directive. End-of-line comments are allowed. Delimited comments are not allowed in a preprocessor directive line.

I flip-flop on this one. On the one hand, I would expect that keeping users from seeing documents until any workflows finish processing should be the default especially for workflows that start automatically when a document is created or modified. On the other hand, though, I can easily think of situation where you would not want this to happen. So I guess Microsoft took the right road by not making it the default. All we need now is a means to hide documents when we have to. Fortunately, it s pretty easy. We take advantage of the security-trimming features of SharePoint (which don t show things that a user doesn t have access to) and use those features to hide our documents until we re ready to show them. First, we need to hide the documents. At the beginning of your workflow, add a Code activity and add the code from Listing 9-22. This code will do two things: Stop the document from inheriting its permissions from its containing document library this automatically causes the current user to be assigned as an administrator on the document. Assign the specific approvers as administrators (or whatever access level you need to give them) to the per-item permission set for the current document.

The SaveComplete() method exists for internal use by CSLA .NET only and should never be used by business or UI code.

Both dedicated and shared server processes have the same job: they process all of the SQL you give to them. When you submit a SELECT * FROM EMP query to the database, an Oracle dedicated/shared server process parses the query and places it into the shared pool (or finds it in the shared pool already, hopefully). This process comes up with the query plan, if necessary, and executes the query plan, perhaps finding the necessary data in the buffer cache or reading the data from disk into the buffer cache. These server processes are the workhorse processes. Often, you will find these processes to be the highest consumers of CPU time on your system, as they are the ones that do your sorting, your summing, your joining pretty much everything.
