  • SmartNavigation and Redirect (not !) again

    Some things just happen twice. I had been battling smart-navigation before . Trying to redirect from code on a page with smart-navigation switched on can lead to blank browser screens. The solution was to set smart navigation to false first before making the redirect. In some recent code I had forgotten...

  • MSDN subscription discs

    Finally tidied up my office. Cleared out a couple of old MSDN subscriptions. A two year old CD european subscription. The Greek Windows 98 brotherly next to the Turkish Windows 2000. Both never been used. I'm still looking for something to do with these piles of outdated discs. These days I have a DVD...

  • WinInfo newsletter no longer considered spam

    For several months I had been digging through my spam mailbox to get WinInfo update and related newsletters. It took some effort, I even built some tools to automate the process, but the content was allways worth it. Since last friday they are back where they belong. They made it out of the blacklist...

  • Mailto links

    Recently my neighbour Warnar blogged a little on sending mail from an app. He explained how to use the smtpserver on the webserver. Recently I needed some mail functionality on the client machine. A web-page should start an email message to be sent by Outlook (Express) or whatever other client used....

  • DotNed and the SDGN

    DotNEd will meet again the 27th of may . Interesting part of the evening will be a presentation by the SDGN , an other Dutch user group with a discussion on “what can the community do for you ?”. A lot ! And what can you do for the community ? Peter

  • MSDN briefings, why developpers do not like security issues ?

    Today I visited the MSDN briefings. Having coded to much (looking for the crtl (shift) B(reak) on the alarm clock in the morning :>) it was time for a day out. Theme of the day was security. The sessions were quite nice, one by fellow blogger Alex Thissen . But at the end of the day a little unrest...

  • Lofar supercomuting and Linux

    Yesterday I blogged a little on the many things interesting ICT project running over here. One of them was the Lofar radio telescope , its heart being a giant supercomputer. Important parts of the project are the network and the computer, but not storage. The main thing the supercomputer will do is act...

  • Lofar, RoboChallenge, GN-IX : the North has it all

    Just over 3 years ago we moved to the north of the Netherlands. To most fellow countryman we might just as well have moved to the moon. It's a two hour drive to get from here to Amsterdam it takes twice as long to get from there to here (according to “western-ers”). The quality of living here is a secret...

  • Good drive !

    At the moment the (Dutch) market is flooded with bargains for external (200-250 Gb) Maxtor hard drives. With a price of just over an euro a gig (excluding VAT) I couldn't resist. After a couple of weeks I'm still so satisfied with it that I just have to blog about it. The drive is fast, the connectors...

  • An optional parameter in a select query

    SqlDataAdapters are great. They provide a nice and maintanable way to get data from the database in and out of typed datasets. The drawback is that you need a new adapter for every new query. Usualy you need at least two select queries to read data, one to get an ordered list of rows and one to get a...

  • Who is that requesting my web page ?

    A quick how to on identifying an user from code. Nothing special, but it works on my (customer's) machine. The default in ASP.NET is that any anonymous user browsing your site is allowed access to all pages. To change that you modify web.config. How to do that is documented in the comments of the web...

  • Do more with less (time)

    Spent last week working on several projects. Had to do several weeks of work in one week. Quite a stress test on me and VS (2003). We all more or less survived. Some reflections : I need a portal. Integrating several web apps by hand makes you feel like reinventing a wheel allready rolling. I need an...

  • Preview data in Visual studio to a (un)-typed dataset

    The last days I've been ploughing through loads and loads of code, including lots and lots of database queries. I totally agree with Brendan , all query results should end up in typed datasets. But in an early stage of the development proces, still figuring out what data I really need, that dataset isn...
