C# with keyword equivalent There’s no with keyword in C#, like Visual Basic. So you end up writing code like this:this.StatusProgressBar.IsIndeterminate = false; this.StatusProgressBar.Visibility = Visibility.Visible; this.StatusProgressBar.Minimum = 0; this.StatusProgressBar.Maximum = 100; this.StatusProgressBar.Value = percentage; Here’s a work around to this:With.A (more)

ParallelWork: Feature rich multithreaded fluent task execution library for WPF

Sunday, March 14, 2010 7:07:24 AM GMT
ParallelWork: Feature rich multithreaded fluent task execution library for WPF ParallelWork is an open source free helper class that lets you run multiple work in parallel threads, get success, failure and progress update on the WPF UI thread, wait for work to complete, abort all work (in case of shutdown), queue work to run after certain time, chain parallel work one after another. It’s more convenient than using .NET’s BackgroundWorker because you don’t have to declare one... (more)

How to convince developers and management to use automated unit test for AJAX websites

Tuesday, March 09, 2010 6:33:05 AM GMT
How to convince developers and management to use automated unit test for AJAX websites Everyone agrees that unit testing is a good thing, we should all write unit tests. We read articles and blogs to keep us up-to-date on what’s going on in the unit test world so that we can sound cool talking to peers at lunch. But when we really sit down and try to write unit tests ourselves – “Naaah, this is waste of time, let’s ask my QA to test it; that’s much more reliable and guaranteed way to test this. What’s t...

Linq to SQL: Delete an entity using Primary Key only
posted by omaralzabiromaralzabir 1172 days, 20 hours, 33 minutes ago
Tuesday, March 09, 2010 6:31:42 AM GMT
Linq to SQL: Delete an entity using Primary Key only Linq to Sql does not come with a function like .Delete(ID) which allows you to delete an entity using it’s primary key. You have to first get the object that you want to delete and then call .DeleteOnSubmit(obj) to queue it for delete. Then you have to call DataContext.SubmitChanges() to play the delete queries on database. So, how to delete object without getting them from database and avoid database roundtrip? You can call this function using Del... (more)

Linq to Sql solve transaction deadlock and query timeout problems using uncommitted reads

Tuesday, March 09, 2010 6:29:15 AM GMT
Linq to Sql solve transaction deadlock and query timeout problems using uncommitted reads When your database tables start accumulating thousands of rows and many users start working on the same table concurrently, SELECT queries on the tables start producing lock contentions and transaction deadlocks. This is a common problem in any high volume website. As soon as you start getting several concurrent users hitting your website that results in SELECT queries on some large table like aspnet_users table th... (more)

Optimize ASP.NET Membership Stored Procedures for greater speed and scalability

Optimize ASP.NET Membership Stored Procedures for greater speed and scalability Last year at Pageflakes, when we were getting millions of hits per day, we were having query timeout due to lock timeout and Transaction Deadlock errors. These locks were produced from aspnetUsers and aspnetMembership tables. Since both of these tables are very high read (almost every request causes a read on these tables) and high write (every anonymous visit creates a row on aspnet_Users), there were just way too many lo...

Memory Leak with delegates and workflow foundation Recently after Load Testing my open source project Dropthings, I encountered a lot of memory leak. I found lots of Workflow Instances and Linq Entities were left in memory and never collected. After profiling the web application using .NET Memory Profiler, it showed the real picture: It shows you that instances of the several types are being created but not being removed. You see the “New” column has positive value, but the “Remove” column has 0. Tha... (more)

ASP.NET AJAX testing made easy using Visual Studio 2008 Web Test Visual Studio 2008 comes with rich Web Testing support, but it’s not rich enough to test highly dynamic AJAX websites where the page content is generated dynamically from database and the same page output changes very frequently based on some external data source e.g. RSS feed. Although you can use the Web Test Record feature to record some browser actions by running a real browser and then play it back. But if the page that you are testin... (more)

Unit Testing and Integration Testing in real projects I am yet to find a proper sample on how to do realistic Test Driven Development (TDD) and how to write proper unit tests for complex business applications, that gives you enough confidence to stop doing manual tests anymore. Generally the samples show you how to test a Stack or a LinkedList, which is far simpler than testing a typical N-tier application, especially if you are using Entity Framework or Linq to SQL or some ORM in data access laye...

Is your computer running slow, battery running out quickly?
posted by omaralzabiromaralzabir 1172 days, 20 hours, 52 minutes ago
Tuesday, March 09, 2010 6:13:17 AM GMT
Is your computer running slow, battery running out quickly? If your computer is running hot or battery running out quickly then it is most likely due to some application or process consuming high CPU or memory. If you keep running applications for a long time, for example, Outlook, then it continues to grow in memory consumption and does not free up memory efficiently. As a result, your computer runs out of physical memory and other applications run slower. Sometimes Outlook, browser, image editing appl... (more)

Do Unit Test and Integration Test from same test code using Conditional Compilation - Omar AL Zabir blog on ASP.NET Ajax and .NET 3.5
posted by omaralzabiromaralzabir 1172 days, 20 hours, 53 minutes ago
Tuesday, March 09, 2010 6:11:52 AM GMT
Do Unit Test and Integration Test from same test code using Conditional Compilation You usually write unit test and integration test code separately using different technologies. For example, for unit test, you use some mocking framework like Moq to do the mocking. For integration test, you do not use any mocking, just some test classes that hits some service or facade to do end-to-end integration test. However, sometimes you see that the integration and unit test are more or less same, they test the sa... (more)
