• How does IIS persist a user's identity from page to page?

  - by Rising Star

  Web pages are, by nature, state-less objects. When you click from page to page in an ASP.net application, each request for a page is treated as a brand-new request. We use things like cookies, session-variables, and query strings to maintain state from page to page. When you log in to an ASP.net web application using Windows Authentication, how does IIS persist your identity between pages?

  - by AlexRednic

  Hello all, my question is stated in the title. How exactly do I do that? I have an open connection and I want to "hijack" it and send my custom messages through it. From my understanding that is done with sockets and their handlers. Any language would do but C#.NET is preferred. Thank you

• Is it possible to add layers to .tiff images with .NET?

  - by Voyta

  Are there any .NET libraries etc. which allow adding layers (with text) to .tiff images? Something like annotations, so that it would be possible to separate them from image afterwards. I tried DotImage - it allows to add annotations, save them as embedded into image and load them afterwards, but no one other image viewer seems to recognize that they are there.

• What are all the concurrent things [data structure, algorithm, locking mechanism] missing in .Net 3.

  - by user49767

  First time I am bit disappointed in StackOverflow cause my http://stackoverflow.com/questions/2571727/c-concurrency-vs-java-concurrency-which-is-neatly-designed-which-is-better question was closed. My intension was just trying to gather knowledge from programming guru's who worked in both the programming technologies. Rather closing this question, please help me by discussing what is good, bad, and ugly in multi-threading part in both the platforms. It is also welcome, if someone would like to compare with .Net 4.0 with JDK 6 (or JDK 7)

• Capture Stored Procedure print output in .NET (Different model!)

  - by Workshop Alex

  Basically, this question with a difference... Is it possible to capture print output from a TSQL stored procedure in .NET, using the Entity Framework? The solution in the other question doesn't work for me. It works with the connection type from System.Data.SqlClient but I'm using the one from System.Data.EntityClient which does not have an InfoMessage event. (Of course, I could just create an SQL connection based on the Entity connection settings, but prefer to do it directly.)

• Does the List in .NET work the same way as arraylist in Java?

  - by eflles

  When I learned Java, I was told that the arraylist works this way: It creates an array with room for 10 elements. When the 11th element is added, it is created a new list with room for 20 elements, and the 10 elements are copied into the new array. This will repeat as until there are no more elements to add, or to a maximum size. Is the List in .NET constructed the same way?

• Is it possible to programatically log access to a windows share (SMB share) using the .Net framework

  - by Ravi

  Just wondering if it is possible to figure out who has read files from a Windows share (using .NET ideally but win32 native will do)? What I'm try to do is create something like awstats for a windows share so I can see who is accessing what and which are the most popular files. I'm not interested in changes - I just want to log access (with time) along with ip / hostname and what file.
