  • UpdatePanel and Sys.Application.add_load Woes

    I’ve found (as others have) an interesting problem with ASP.NET AJAX’s Sys.Application.add_load function.  It doesn’t quite work as expected in all browser environments, under certain conditions. We have several ASP.NET based controls that use a lot of JavaScript on page load to initialize, and most of these controls are supposed to support ...

  • KeepAlive for the DotImage WebThumbnailViewer

    This is my third post on the topic of using a simple JavaScript call to keep a server session alive. My first post was on keeping a generic IIS session alive by reloading a hidden GIF, my second was related directly to keeping session state alive for the WebImageViewer, and this post will address the WebThumbnailViewer. Using the ...

  • KeepAlive for the DotImage WebImageViewer

    Recently, I posted an article describing a simple way to keep a session alive during long periods of inactivity. That works great if your web application doesn't rely on some other information on the server to maintain state. If you use DotImage in your web app, it maintains certain state information in the AtalaCache that needs to be updated ...

  • Changing Your Garbage Collector Settings on the Fly (.NET Memory Management: Part 5)

    It has come to my attention via a recent DZone article that .NET 3.5 and 2.0 SP1 jointly included a new feature which lets you manipulate the way your garbage collector acts programmatically.  This can be done through changing the value of a new property of the System.Runtime.GCSettings class named LatencyMode. In this article I will walk you ...

  • A Note Regarding YUI and the WebImageViewer

    When developing two of my applications for 31 Apps in 31 Days (here and here), I discovered an issue with using YUI with our WebImageViewer. The script tag that references the YUI js files must be inside the main form element. If it is not, the DOM of the WebImageViewer gets distroyed and multiple painful errors ...

  • Queuing up Your Remote Invokes

    The WebImageViewer is a very powerful web control that we offer to our customers. It does a lot of work for you behind the scenes to make the experience as application-like as possible. It even takes that a step further with the RemoteInvoke method and RemoteInvoked event by providing customers with the ability to make server-side function calls ...

  • The Cursed History of Smalltalk in .NET

    After my last blog post, due to some of the responses, I decided to spend some time with Smalltalk.  As a DotNET developer by trade, I wanted to see what kinds of options were available for use on the CLR.  Unfortunately, out of the five different DotNET Smalltalk flavors that have been created, not a single one is still under ...
