Five XHTML Elements You Didn't Know But Were Afraid to Ask - The Code Project - HTML / CSS Download demo project - 1 Kb Introduction With experience, working with ASP.NET, I noticed some important XHTML tags that are rarely used by web developers, even the experienced ones, so I thought of writing this article to promote them. Most of the mentioned elements are HTML compatible, but all of them are XHTML compatible. The elements are optgroup, label, fieldset/legend, col/colgroup and acronym. 1. optgroup <label for="county">County</label><select id="county"> <optgroup label="England"> <option>Surrey</option><option>Kent</option> </optgroup> <optgroup label="Scotland"> <option>Orkney</option> </optgroup></select><label for="languages">Languages</label><select size="6" multiple="multiple" id="languages"> <optgroup label="Classical"> <option>C#</option><option>C++</option><option>Java</option> </optgroup> <optgroup label="Web"> <option>ASP.NET</option><option>PHP</option> </optgroup></select> 2. label The label element provides a caption for a form element. 3. fieldset/legend 5. acronym

Windows Administration Inside the Windows Vista Kernel: Part 2 Mark Russinovich At a Glance: Memory management Startup and shutdown Power management Last month, in the first installment of this three-part series, I looked at Windows Vista kernel enhancements in the areas of processes and I/O. This time I'll cover advances in the way Windows Vista manages memory, as well as major improvements to system startup, shutdown, and power management (Part One). Every release of Windows® improves scalability and performance, and Windows Vista™ is no different. Four performance-enhancing features that use new technologies make their operating system debut on Windows Vista: SuperFetch, ReadyBoost, ReadyBoot, and ReadyDrive. Dynamic Kernel Address Space Windows and the applications that run on it have bumped their heads on the address space limits of 32-bit processors. Memory Priorities

Cool Client Stuff : Client Settings FAQ While the feature is easy to use in general, we often get questions from users trying more advanced scenarios about why a certain aspect of the feature works in a particular way or how to customize some behavior. The answers to these questions are generally in the MSDN docs, but can sometimes be hard to find. I thought it would be useful to cover this information in a FAQ for easy future reference. I will be updating the FAQ as and when there are more questions to add. Q: I notice there are two kinds of settings - application scoped and user scoped. A: There are two main types of settings that applications generally want to store: (1) certain data like connection strings and web references that don't change often, but should be possiblep for an admin to change and therefore cannot be hardcoded into the application and (2) user preferences and customization that can change any time. Q: You said user.config files go in the user data path. where The file name is always simply 'user.config'.
SObjectizer: I Love This Game! Автор: Евгений ОхотниковИнтервэйлИсточник: RSDN Magazine #4-2005 Опубликовано: 31.03.2006Версия текста: 1.0 Введение О чем речь В этой статье я попытаюсь немного расказать об инструменте, в разработке которого мне повезло участвовать. В настоящее время разработчики SObjectizer стоят перед вопросом: стоит ли из внутреннего инструмента сделать SObjectizer одним из продуктов компании? Тем не менее, выпуск SObjectizer как отдельного продукта станет серьезным испытанием. Имеет ли вообще смысл этим заниматься? Расказывая про SObjectizer, я не могу быть бесстрастным и полностью объективным, ведь над SObjectizer я работаю с момента его зарождения. Немного истории Началось все с того, что в гомельском Конструкторском Бюро Системного Программирования (КБСП) в 1994-96 годах сложилась команда, которая под руководством Аркадия Косарева попыталась создать объектно-ориентированную SCADA-систему (Supervisory Control and Data Acquisition).

Solve problems by writing a note to yourself Dear, Merlin, For someone so fond of lecturing other people about their problems, I have a lot of annoying tics (I mean, duh). One of my worst, at least back in the day, was seldom bothering to RTFM before demanding lots of time-consuming help from others. For years, my court of first resort was almost always to email the smartest, often busiest person I knew about a given topic, alerting them as to their new role as the speed bump between me and solving my problem (cf: the classic Balloon joke). The funny thing I eventually realized was that I could and often did find the solution to my problem -- part way through writing the email in which I was asking for help. Seriously, open up your email program, type in your own email address, then choose a brilliant subject line that perfectly encapsulates your particular problem. Next, explain the ways you've already tried to solve this problem, including any alternate solutions, workarounds, hacks, reboots, etc. Love, Merlin p.s.
How to write friendlier code for the Garbage Collector and to gain performance boost - The Code Project - C# Programming Introduction Memory management is a very important issue, even, now, in the world of managed programming languages where the .NET Framework encapsulates it entirely. In my humble opinion, it is mandatory for developers to understand the memory management process in a managed environment. The old school of developers knew much more about memory management than the novice ones mainly because they had to. Disclaimer I am not an official expert of the Garbage Collection mechanism. Why writing the article? I guessed it would have been nice to share, with the CodeProject community, the knowledge about working correctly with memory allocation in managed code. Who should read this article? Anyone who writes managed code, in any of the .NET languages, and is keen about writing better performing code. What you will not find in the article Garbage Collector assumptions It is important to read the following section before you continue. Here are the published rules which the .NET GC complies to: Cache it!
If broken it is, fix it you should : .NET Memory Leak Case Study: The Event Handlers That Made The Memory Baloon It always feels like issues come in clusters. One week we get tones of cache related cases, next week everyone is stuck in some lock and so on. Lately I have had a number of issues where there were memory leaks related to event handlers. Problem description We have a pretty easy to repro memory leak, even with very few users memory grows at a high rate and the memory is never released. The usual suspects are eliminated, i.e. we know that the app doesn’t cache much or store much or anything in session scope, and from performance monitor we can see that as private bytes grow, most or all of this growth is in the .net heaps (if private bytes grow by 100 MB, # bytes in all heaps also grow by about 100 MB). Gathering data Since we can tell with ! Preferably to make the problem more visible, a stress test is nice so that the leaking objects stand out more. Debugging As usual I have simplified the scenario a bit, but the debugging techniques stay the same. ! 0:000> ! Dump 1: Dump 2: 0:000> ! ! If we do !
ScottGu's Blog : Tip/Trick: Optimizing ASP.NET 2.0 Web Project Build Performance with VS 2005 This posts covers how to best optimize the build performance with Visual Studio 2005 when using web projects. If you are experiencing slow builds or want to learn how to speed them up please read on. Quick Background on VS 2005 Web Site Project and VS 2005 Web Application Project options VS 2005 supports two project-model options: VS 2005 Web Site Projects and VS 2005 Web Application Projects. VS 2005 Web Site Projects were built-in with the initial VS 2005 release, and provide a project-less based model for doing web development that uses that same dynamic compilation system that ASP.NET 2.0 uses at runtime. Both the VS 2005 Web Site Project option and the VS 2005 Web Application Project option will continue to be fully supported going forward with future Visual Studio releases. To migrate from the VS 2005 Web Site Project model to the VS 2005 Web Application Project model, please follow this C# or VB tutorial that walks-through the steps for how to-do so. Hope this helps, Scott
