App_Data cannot contain images
Until today I didn't know that the App_Data folder cannot contain images. Well, actually it can, it's just that the images won't be served, for security reasons. Normally I wouldn't put my images in the App_Data folder but rather in a Images folder beneath the root, but I was just testing something today and trying to add an image to a treeview node i put it in the App_Data foder just because the folder was already there. And then I spent the next 10 minutes trying to figure out why the image wouldn't ......

XmlWriter's Close bug
I've looked around on the net but didn't find anything about what seems like a bug in XmlWriter to me. The thing is, in .net 2.0, instead of doing a new XmlWriter(), there is now a static XmlWriter.Create method, with a number of overloads. That stated, can you spot anything wrong with this code: XmlWriter writer = XmlWriter.Create(new FileStream("test.xml", FileMode.Create)); // do some stuff writer.Close(); I didn't, but as it turns out, this does not close the FileStream used by the XmlWriter. ......

Global Resources weirdness
A colleague of mine asked me today if there is a better way to set the CurrentUICulture in asp.net 2.0 than handling Application_BeginRequest and doing Thread.CurrentUICulture = new CultureInfo(foo). He asked me this because he was doing something like CommonStrings.Culture = new CultureInfo(whatever), where CommonStrings is a .resx file residing in our App_GlobalResources folder. As you might know, asp.net 2.0 generates a wrapper class around string resources for strongly typed access, so instead ......

Themes + base != love
In the current project I'm working on, we have to have an “export to pdf” functionality for each page. So we've been using webSupergoo's ABCPDF successfully until yesterday, when I found that we could change the way we're inserting the css stylesheet into the pages for the better. We used to do this: <link rel="stylesheet" href="<%= ResolveUrl(AppConfigurator.... %> " type="text/css"> ...where AppConfigurator is a static class holding a reference to a static NameValueCollection, ......

Cookieless Forms Authentication and Redirection
Here's one that had me scratching my head for a bit.As you might know, in asp.net 2.0 you can choose to have cookieless Forms Authentication (http://msdn.microsoft.com/... Basically, what this means is that your pages Url's will get increased by about 200% :) because asp.net no longer stores the forms authentication information in a cookie, but directly in the Url. Also, you can have cookieless session state, meaning some extra characters get added again in the ......

Hello World
Hello fellow bloggers, Yea...umm... this sets out to be a blog where i'd like to jot down various problems and oddities (at least for me) that i run into through my .net developer life. Hopefully i won't be excessively boring and bring some interesting stuff to the table. Also, i want to ask for your forgiveness if my English is poor (not a native speaker) or the subjects seem trivial. Basically, i'd like this to be a place that helps me refresh my short (rodent :)) memory so i don't have to solve ......
