  • Browser peace and where (VS) 2005 can help.

    In a comment on a recent post on using IE and FireFox to debug ASP.NET apps , Boucher states that it is maybe too far for a peacefull world. The point of my post was that an ASP.NET 1.x app behaves different in IE and Firefox but that an ASP.NET 2 application behaves the same in the two browsers. That...
  • Tablet PC junior

    Far fetched ? Both devices have a pen with a static magnet in the tip. Not interoperable. Could you imagine your kid enjoying a keyboard like this ? Merry Christmas Peter

  • Tablet API : GetDefaultRecognizer() behavior

    The tablet PC is great in recognizing handwriting . But to be able to recognize it needs a language specific recognizer. These are avaliable for several languages. In the API is the GetDefaultRecognizer method which returns the default recognizer for the system. The simplest overload does not need any...

  • Password fields

    A small security related item. I'm a lazy typer and love to copy things. Outlook Express makes quite clear that that is not allowed on a password field A password on an ASP.NET page (a textbox whose TextMode property has been set to Password ) has a similar behavior. It will not pop up the balloon, it...
  • Debugging a webservice with Firefox

    Recently I did some research on using Firefox as browser to debug asp.net webapps . Andre points out in a comment this does not seem to work with webservices. There is one thing you have to watch to debug these. When you start a webservice the browser pops up and displays an overview of the service....

  • SDN mobility conference

    Last friday, december 17th, Dutch user group SDN organized a meeting entirely dedicated to mobility. It was lovely; imagine a day spent entirely on Pocket PC, Tablet PC and the like. The presentations went far beyond the usual “hello world” demo's. Especially the .net compact framework is...
  • Viewstate (hog) and the datagrid

    Sometime ago I had been wrestling through the viewstate and blogged on it . On a page with a datagrid the viewstate can be enormous. As the viewstate travels over the wire on every roundtrip this can be quite a problem in a situation where the bandwidth is limited. A lot of data in a datagrid is reread...

  • Recognizing handwritten text on a tablet PC

    Way back on primary school (1963) my teacher tried to learn me to write. First with a pencil, later with a pen. It never was a big success, over the years I always had insufficient marks and nobody (including myself) could usually read what I had written down. Which made me a very early adopter for typewriters...

  • Tablet PC : What can and what cannot be overlaid with an InkOverlay object

    Part of the tablet PC API is the Inkoverlay class. The constructor takes a control or even a windows handle. The user can scrible on the associated window. You can pass almost any handle to the constructor, like the handle of an ActiveX control on your Winform. This snippet makes the calender ActiveX...

The conference is actually a combination of several conferences, including Microsoft Windows Anywhere . There is a tablet track, a tablet pre-conference and a post-conference...

    Those of you who visited the 2003 PDC propably remember the slogan “ Does your code think in ink ? ” It was a contest for cool tablet PC apps. Finaly a winner is declared, PC magazine has published a good overview of the top tablet apps. If you have a tablet do check out the winning ArtRage...
  • How to find out which control was responsible for the postback of an ASP.NET web form

    This sounds and is so trivial that it is well hidden in the docs. On my form is a datalist with in each row a label and a radiobuttonlist. On the radiobuttonlist autopostback is set to true, selecting another radiobutton will lead to a roundtrip. The items of a datalist are templates so there are no...
