1 of 153 | HOWTO: Change IIS User Impersonation Token - Question: Hi, We are using our third party component for doing authentication and authorization with IIS6 web server on win2k3 X64 EE. Here we are using IMPERSONATION concept for this integration. Can anybody describe the required configuration which are needed at IIS 6 for successfully impersonation of users with third party component? Should we need to set Anonymous authentication explicitely for this kind of configuration? Answer: Third party code will not be able to directly impersonate and have IIS use that user token. IIS will: Strip off the impersonation token after ISAPI Extension returns control to it Ignore and re-apply IIS's desired impersonation token if ISAPI Filter c......

4 of 153 | JSONVid: Pure JavaScript Video Player - Jacob Seidelin went on a ( crazy :) ) mission to create a pure JavaScript video player that didn't use Flash: My first thought was to read binary video files using a technique like the Andy Na posted about here, figuring that there must be some really simple to parse video formats around, but I soon changed directions and decided to make up a whole new video format. Enter.. JSONVid. Using a player like mplayer, it is easy to export all frames in a movie clip to individual jpeg files, and using whichever language you prefer it is also fairly trivial to collect these files, base64 encode the bunch of them and throw them all together in a nice JSON file (I used this PHP script). The forma......

In our application, sometimes we would like to use XMLSerializer for optimization. This will create XMLSerializer.dll in your application. This XMLSerializer.dll we normally dont want to download everytime, when we publish our application again after some changes and want it to be downloaded for specific set of users. We can create a separate group for XMLSerializer.dll in ClickOnce, which will specify it to be downloaded to some set of user who belongs to that group.

Sometimes a list might contain sensitive information, such as the social security number for an individual.  Once this information is entered into a SharePoint list, it is stored in the content database in plain sight of anyone that is able to view the database.  We should implement stringent security to limit who can access the database, but it can also be good to add another layer of security protection for the sensitive data......

I have detailed how I did this here Because I could not fetch the icons directly using HTTPService I have used a cgi proxy script written in Python to fetch the target icons and convert them into a Base64 encoded string before returning the data to the Flex application.

I understand I haven't gain anything on the web traffic, but it surely simplified my JavaScript programming. Let me go through what I did Step 1.  Extract the XML Schema.

16 of 153 | Use of SGEN.exe to avoid common XmlSerializer performance pitfalls - This week, I encountered a test scenario which makes use of an XmlSerializer on it's startup path. Unfortunately, MSDN's documentation for the type is not clear on the performance impact of using an XmlSerializer. The documentation on introducing XML serialization, found here, actually mentions the solution, but it also does not state what the problem is. When you use an XmlSerializer, a helper assembly(1) with a custom type for serializing your type is created. The C# CodeDom is used to generate this code, which then is compiled by the C# compiler. The runtime must then load this generated assembly, and JIT the code. Additionally, a separate assembly is generated for each type you create ......

17 of 153 | "New" Statement Considered Harmful - All of us have probably written code like this: Foo f = new Foo(); And what could be simpler?  As long as the logic in the constructor is simple (or better yet, the constructor is empty), it would seem that the simplest code is the best, so just use the constructor.  Certainly the MSDN documentation is rife with code that uses public constructors.  You can probably find plenty of public constructors used right here on my blog.  Why invest the effort in writing (and using) a factory class that will probably never do anything useful, other than call a public constructor?

A couple of weeks ago I implemented a site-wide script that unblocks ads which were blocked by Adblock Plus. See, a while ago, when the whole firefox is blocked debacle was raging, I made some hand-waving statement about how easy it would be to circumvent ad-blocking software (though of course, I wouldn’t say how).

Let’s set this up.  First, I have an existing schema like below where my datetime/number types are both nillable, and have a minOccurs of 0.  So, they could exist and be null, or not exist entirely. Next, I generate a typed object for this schema using xsd.exe.  The generated class contains my schema nodes, of course, but xsd.exe also inserts these boolean “[fieldname] + Specified” variables.  Now these field accessors have the XmlIgnoreAttribute, so they don’t get included in the XML document, but rather can be used ......

27 of 153 | User Interface Messages and Strongly Typed Messages - Some time back I wrote an article about how to store and retrieve the user interface messages. When I say user interface messages I meant the messages we display on the screen to notify the user of some operation. These messages can be "Account has been created!", "Details have been updated" and so on. You can view the article here. One problem with the above approach was the weak typing. This means that if I had to display a login successful message I had to send the string "LoginSuccessfull" to the GetMessages(string elementName) method. This introduces bugs and becomes harder to maintain. There is another way to accomplish the same task with the benefit of strong typing. This method in......

I don't see any reason why JSON has different streaming characteristics than XML. Every JSON parser I've written has a streaming I/O layer at the bottom and defers buffering (and type mapping) to a layer above, just like most modern XML stacks.  Why is XML inherently more streamable? 2. Like Joe Gregorio states in the comments on Tim's post, I also prefer JSON's simplification of only allowing UTF-*-based encoding. 3. Tim states that you should use XML when the order of data matters, but JSON has a perfectly reason......

Today I figured out that, when using the DataContractSerializer, you need to make sure you provide a setter implementation even for your collection based properties. Once again, this is a departure from the way that the XmlSerializer works. I'm trying to work through the scenarios where this is any kind of improvement over XmlSerializer, but I cannot think of any problem this solves.

This effectively limits Internet e-mail to messages which, when transmitted, include only the characters sufficient for writing a small number of languages, primarily English.
