Static Class for Beginners

  
In general, the members of a class can be accessed by instance of that class when they are in public, but there comes a situation to access or call members of a class without an instance and this can be achieved by declaring them as static

abstract away the source of the connection string using a class with a static property.

  
ASP.NET provides a configuration system we can use to keep our applications flexible at runtime. In this article we will examine some tips and best practices for using the configuration system for the best results.

The element of a web.config file is a place to store connection strings, server names, file paths, and other miscellaneous settings needed by an application to perform work. The items inside appSettings are items that need to be configurable depending upon the environment, for instance, any database connection strings will change as you move your application from a testing and staging server into production.

Let's abstract away the source of the connection string using a class with a static property.

NUnit and public static readonly

  

I have an app that I am testing with NUNit.  The project im testing has several helper classes that are created as public static readonly.  When I run the NUnit tests, they all fail with the same error

SetUp : System.TypeInitializationException : The type initializer for 'Systems.Utils.ConstantHelpers' threw an exception.
  ----> System.NullReferenceException : Object reference not set to an instance of an object.

Concurrent Affairs: Build a Richer Thread Synchronization Lock

  

In my last column, I showed the various thread synchronization mechanisms employed by the Microsoft® . NET Framework (see Concurrent Affairs: Performance-Conscious Thread Synchronization). I then examined the performance characteristics of all these mechanisms and determined that the Interlocked methods performed the best because the calling thread never has to transition to kernel mode.

Memory Models: Understand the Impact of Low-Lock Techniques in Multithreaded Apps

  

Because the use of low-lock techniques in your application significantly increases the likelihood of introducing hard-to-find bugs, it is best to use them only when absolutely necessary. Here Vance Morrison demonstrates the limitations and subtleties low-lock techniques so that if you are forced to use them you have a better chance of using them correctly.

C++ Q&A: Performance Monitoring, Managed Extensions, and Lock Toolbars

  

In the June 2004 issue of MSDN®Magazine, I described a class called ShowTime that you can use to do simple performance monitoring for your app. ShowTime uses its constructor/destructor to record the start/stop times of its existence so you can instantiate it in a block of code like so: { ShowTime st(_T("Total time is:")); // some lengthy operation } .

How best to deal with a static C Library which is currently 32-bit?

  
My application is a mix of a number of different executables and DLL's that are both managed and unmanaged code.  One thing everything has in common is the licensing library which is written in C as a static library.  The managed code is gaining access to this static C library via a C++ CLI assembly which links in the library.  I would like to start offering the managed code as a 64-bit app, but I don't know exactly how to overcome the issue with the static C library and the C++ CLI assembly that consumes it...Assuming I port the static C library over so that there is also a 64-bit version, is there any way I can keep the C++ CLI code bit agnostic and link in both the 32-bit and 64-bit, allowing the Windows loader to use the correct one based on the machine it is running on?  If not, how does one go about telling the C++ CLI code to use the 32-bit library when compiling the C++ CLI to target a 32-bit process and 64-bit library when targetting a 64-bit process?Sam

Report with Static Layout (Restrict Rectangle Growth/Static Tablix size)

  
How do you stop a Tablix or the rectangle that is a Tablix is contained in from growing.  I have been designing a report that must have a very specific layout due to government and commericial policies.  In this report is a header on top, a footer, some other reporting data above and below a rectangle that contains a tablix region.  I need this tablix and/or rectange to stay a constant size, if there are more rows, it should start another page in the report.  Instead, it grows and pushes all the datafields below it, down and off the page.    I have also tried this with a frame.  The table must show within the frame on form only.  The frame can contain maximum of 10 rows, but the table will grow outside the frame and the items below are pushed down and off the page.  I cannot see how I can setup a page break on every 10th row on a table. Does anyone know how setup a constant size Tablix/Table in a rectangle or frame so that it will not grow beyond the specified size (so the data fields below it will not be moved) and will instead create a new page?  This is crucial to our application and we may have to switch reporting solutions if we can get this figured out. Thanks for you help!
