AppDev: Something You Should Know by Irena Kennedy

I’m working on a project where a service hosted elsewhere requires Windows authentication. As a consultant, my computer is not on the customer’s domain, so, using my logged-on Windows credentials won’t do any good. And, doing nothing...

Doing a web search for a difference between basicHttpBinding and wsHttpBinding, I find just generic references to basicHttpBinding being a basic implementation of SOAP1.1, and wsHttpBinding supporting all the WS-* spec. So, I did a side by side comparison...

Consider the following line of code: AttendeeAvailability attendeeAvailability; . . . if (attendeeAvailability.WorkingHours.DaysOfTheWeek.Contains(DateTime.Today.DayOfWeek) == false) { . . . } You’ll get a compile time error -- Argument 1...

Let’s say you need to quickly find some reference/lookup data and you decide to use hashtables… If your key is comprised of several elements, is it better, from the performance point of view for you to combine all of them into one string...

John Manaloto, one of the architects I’ve worked with recently, has been kind enough to allow me to publish the “smart cache” class he’s put into one of his projects… It’s a component built on top of Microsoft Caching...

Once in a while, I post non-technical gems I come across… This one was one of those hard to pass by and not to share… I got it through a couple of forwards, and the original, accurate author information is not known – if somebody knows...

Last weekend I wrote a utility that does file synchronization (yes, I know there many such tools), but where I can define in advance what I want to see happen if there are discrepancies, e.g.: If you think you might benefit from it, attached is...

Last weekend I wrote a utility that does file synchronization (yes, I know there many such tools), but where I can define in advance what I want to see happen if there are discrepancies… To do that, I needed a class that would take an array of...

My current project uses Silverlight 4.0 and RIA services, and I quickly came to realize the benefits and the challenges of all DomainService calls being asynchronous. Consider this scenario: a Silverlight client app needs to get some data, that...

Special thanks to David Petersen who has submitted this post! If you ASP.NET page that contains the Report Viewer Control, has double scroll bars, you can remove them by including two separate form elements on the page: 1. First <form>...

This is an update to http://blogs.msdn.com/b/irenak/archive/2009/12/16/sysk-375-visual-studio-add-in-for-managing-configuration-files-across-environments.aspx . The provided code is upgraded for Visual Studio 2010, and also now supports nested projects...

All the credit for the information in this post goes to Marc DeAntoni, and other Internet posts/articles that helped Marc get to the root cause! On my current project, we were working on a proof of concept application measuring how many editable...

I like to view photo images (.jpg files) using Large or Extra Large Icons view in Windows Explorer. Unfortunately, this view doesn’t give me a way to sort the files by DateTaken property… So, as a workaround, I created a small application that uses the...

One of common customer questions/requests I get is about industry best practices and recommendations on managing configuration file settings when deploying code across environments. There are several options to change different configuration settings...

Traditionally, to implement role based authorization in .NET you would use PrincipalPermission attributes, e.g.: [ PrincipalPermission ( SecurityAction .Demand, Name = "YourDomain\\User1" , Role = "YourDomain\\Role1" )] public void MethodX( ...

If your WCF services use role based authorization, and you need to pass the identity of the end user (original caller), you have a few options: 1. Use <identity impersonate=”true” /> in web.config This is not my preference since there...

As many web sites point out, TFS uses policies to implement a requirement that developers provide comments when checking in code. The policy must be deployed to each developer (client machines). The Team Foundation Server Power Tools include the Changeset...

Sometimes it’s necessary to test application performance in low available resource situations… I’ve seen tools that simulate low available memory, do network throttling, etc., but I have not come across one that simulates a lot of SQL Server connections...

First, for those who may not be familiar with this feature, .NET 3.5 allows developers to add methods to existing types without using inheritance or partial classes by creating static methods that can be invoked by using instance method syntax. ...

If, from time to time, you delete some files & folders from your hard disk, either because it’s no longer needed or just takes too much space and needs to be moved elsewhere, you may find the following utility useful… Basically, the tool below...

First, I must start with the following disclaimer – this was my first SharePoint 2007 project, so, I do not claim any expertise in the subject matter… However, I believe, this post may be of value to some readers… Let’s say, you want to add a custom...

Do you wish there was an easier way to save individual messages to your hard disk in Outlook 2007? Moreover, do you want this utility to automatically modify the file name making it unique? For example, you may want to search for all messages from/to...

As a consultant, I frequently work at my customer sites, and at my home office. Needless to say, remembering the proxy configurations, and changing them every time I plug in is a chore I’d rather delegate to software running in the background and automatically...

If you want to test code that requires an MTA threading model (e.g. the code being tested uses WaitHandle.WaitAll), you need to change the .testrunconfig file manually and change the threading model from STA to MTA. There are other posts that say...
