Book Recommendation - Working Effectively with Legacy Code

By
On my Google+ account, I recently saw news on my feed from a friend of mine Robert Dailey, seeking a good book on implementing automated testing in existing, complex projects not initially designed for it. It was recommended that he check out a book titled, Working Effectively with Legacy Code (ISBN-13:978-0131177055), by Michael Feathers. It has a wealth of knowledge on bridging the gap between legacy (test-less and/or untestable) code and newer, testable code. Definitely, worth the read.

C# - ListView Item Spacing (Padding)

By
I'm perplexed at the reasoning that the ListView control, has no direct spacing/padding property. I am utilizing the ListView in the capacity of images, using the View state, View.LargeIcon. There is a method to modify the spacing/padding between the ListViewItem(s). Initially, you'll need to add: using System.Runtime.InteropServices; Next, you'll need to import the DLL, so that you can utilize SendMessage, to modify the ListView parameters. [DllImport("user32.dll")] public static extern int SendMessage(IntPtr hWnd, int msg, IntPtr wParam, IntPtr lParam); Once completed, create the following two functions/methods: public int MakeLong(short lowPart, short highPart) { return (int)(((ushort)lowPart) | (uint)(highPart << 16)); } public void ListViewItem_SetSpacing(ListView listview, short leftPadding, short topPadding) { const int LVM_FIRST = 0x1000; const int LVM_SETICONSPACING = LVM_FIRST + 53; SendMessage(listview.Ha

C# / SQL - Performing Distributed Transactions

By
Distributed Transactions span across multiple processes, which when encapsulated by the distributed transaction manager, will either commit a successful transaction or rollback changes. Distributed Transactions have been available within .NET, since .NET Framework 2.0. The Default Isolation level is set to Serializable , which in usage, creates unnecessary blocking and deadlocks. Therefore, it is suggested you override the default isolation level to ReadCommitted, which reflects the default within SQL Server. /// /// This class is responsible for performing Distributed Transactions. /// public class DistributedTransactionUtility { /// /// The Distributed Transaction method which creates a Transaction Scope object /// and commits if there is no error and rollbacks, incase of exception. /// /// /// The method which performs multiple DB Transactions. /// public void DoDistributedTransaction(Action method) { // Initializes Transac

IIS / ASP.NET - Disabling Compatibility Mode/View (Internet Explorer)

By
In ASP.NET, if you need to disable compatibility view of the end users using your application, you can override the respective browser (Internet Explorer) compatibility mode, by setting the compatibility mode to Edge. By using this setting, the users of the web application, will render using the latest rendering engine available. If in the scenario you don't want to use the latest, you can also define other standards, such as IE8, IE9, etc. This can be defined in the master page/view using the following meta tag within the <head> section: ... Note: The X-UA-Compatible meta tag will need to be the first meta tag, in the circumstance that setting the IE rendering engine to Edge, is not working as intended. and web.config, by adding a custom header using X-UA-Compatible to the response headers, ...
