Vorbei sind die Zeiten grauer, langweiliger Webanwendungen die hauptsächlich aus einer Ansammlung von Texten und Links bestanden. Der aktuelle Trend geht zu interaktiven, reichhaltigen Anwendungen welche die Features und Funktionalitäten traditioneller Desktopanwendungen in einer Webanwendung im Browser zur Verfügung stellen. Ermöglicht wurde dieser Trend u.a. durch ein Programmiermodell welches heute unter dem Namen Ajax (Asynchronous JavaScript and XML) in aller Munde ist und die inzwischen zahlreichen Ajax Frameworks, welche die Entwicklung komplexer Anwendungen deutlich erleichtern. Dieser TechTalk gibt einen Überblick über das ASP.NET Ajax Framework von Microsoft. Daniel Walzenbach, Developer Evangelist der Microsoft Deutschland GmbH, vermittelt...
Was ist das Problem? Vielleicht haben Sie schon bemerkt, dass clientseitige IDs von Controls gelegentlich von den ursprünglich vergebenen IDs abweichen. Dieses Phänomen tritt immer dann auf, wenn Controls in Container eingefügt werden, die das Interface INamingContainer implementieren. Anbei ein kleines Beispiel: < asp : Content ID ="Content2" ContentPlaceHolderID ="ContentPlaceHolder1" runat ="server"> < asp : TextBox ID ="TextBox1" runat ="server" /> < br /> < asp : Button ID ="Button1" runat ="server" Text ="Button" /> </ asp : Content > In diesem Beispiel wurden zwei Controls in einen ContentPlaceHolder eingefügt woraus ASP.NET den folgenden Markup Code erzeugt: < div > < input name ="ctl00$ContentPlaceHolder1...

Hi Everyone, Welcome back!!! As mentioned earlier, today we will be wrapping up with the discussion about the ASP.Net 2.0 reserved folders. Let's take a look and understand the other ASP.Net special folders that we didn't consider yesterday. The App_Data Folder: The App_Data folder is expected to contain data stores local to the application. It typically contains data stores in the form of files such as Microsoft Access or Microsoft SQL Server Express databases, XML files, text files, and whatever else your application can support. The contents of the folder are not processed by ASP.NET. The folder is the default location where ASP.NET providers store their data. Note: The default ASP.NET account is granted full permissions on the folder. If...
Hi Everyone, Welcome back!!! As mentioned earlier, today we will discuss about the ASP.Net 2.0 reserved folders. There a number of reserved folders that you will see applicable to an ASP.Net 2.0 application. We will now try to understand what each of these is and what their respective purposes are. As there are many such folders, and each has its own associated concept, we will see a few today and the remaining tomorrow: Folder name File Types Notes Bin .dll Contains any prebuilt assemblies required by the application. App_Browsers .browser Contains application-specific browser definition files that ASP.NET uses to identify individual browsers and determine their capabilities. App_Code .cs, .vb, .xsd, custom file types Contains source class...
Hi Everyone, Welcome back!!! We again missed a couple of days and most of you know what most of us were busy with in the last 2 days :-) :-). So, as mentioned earlier, today we talk about ASP.Net site pre-compilation. Application Pre-compilation: By default, each public resource of an ASP.NET site is compiled on the fly only upon its first request. This introduces a first-hit delay as a result of the compilation process. Since the advent of ASP.NET 1.0, developers have raised the issue of site pre-compilation. Site pre-compilation brings a double benefit: no delay for requests because of compilation and no need of deploying source code to the Web server. Further, as do classic Windows executables, precompiled sites offer a high degree of protection...
We skimmed through some basics of ASP.Net compilation model and the ASP.Net runtime environment yesterday. We mentioned the 2 process models that ASP.Net supports; we will see more inside these 2 models today. ASP.Net Process Models IIS 5.0 Process Model On IIS 5.x all ASP.Net applications run inside a separate process called aspnet_wp.exe. So in this model aspnet_isapi doesn't actually process the requests, it is hosted within the inetinfo process of IIS but it acts as a dispatcher, collects all the information available about the invoked URL and routes the request towards this distinct process aspnet_wp also called the ASP.Net worker process. The communication between the ISAPI extension and the worker process takes place through named pipes...
Es ist unglaublich! Ich bin immer wieder fasziniert wie viele interessante Informationen innerhalb von Microsoft ausgetauscht werden! Zusätzlich zu internen Seiten der Produktgruppen, Mailinglisten, Blogs, Wikis, etc. hat mein Kollege Sukesh Khare angefangen täglich Informationen rund um das Thema ASP.NET 2.0 zu veröffentlichen. Innerhalb der nächsten 2-3 Monate plant Sukesh die Themen Compilation Model Configuration Provider Model Out of band technologies Web Parts Mobility Site Navigation Iterative Controls User Controls Custom Controls zu behandeln und er hat mir erlaubt, diese Infos auf meinem Blog zu veröffentlichen :-)) In diesem Sinne viel Spaß mit den "Daily .Net Feeds"! Daniel Hi Everyone, Welcome again to a new edition of Daily .Net...
