A while back I was trying to consume some XML from a third party site and I found myself getting stuck on an error.  The site would not give me a valid response and would throw up a 403 error.  After digging around I found that I left off the user-agent info in the request header.  So the moral to this story is: Don't forget your user-agent!

Goal:
The label control adds <span> tags around the text when rendered, I needed to have these removed. I also show how to replace the <span> tag with whatever tag you would like.

I currently work on a site that has a custom built CMS, which is not always a good thing.  Now don't get me wrong there are some great ideas in this home grown CMS, but just like any application there are some wrong/bad things as well.  Here is one of those bad things that I had the time to fix recently. 

The web site content is entered via a WYSIWYG editor by whoever is responsible for the content, this markup (from the WYSIWYG) is stored in the database along with flags/keys that determine when to display this content.  If a few content items score the same then they all get built together, each one in its own Label control.  This is all fine and dandy, but when it comes time to dynamically create this content and add it to the current page is when they go less than ok.  Because of some limitations of the rest of the framework the content has to be built inside a System.Web.UI.WebControls.WebControl, ok this is fine except we are limited to a select few controls that fall into that category.

I recently changed the layout of some of my categories in BlogEngine.Net 1.4.5.0.  In short I wanted to add a few parent Categories for the categories that I was already using.  For example: I have a category name ".net" that I lump all of my .net related items in but what if I also have some java code or C++ code and I have a category for them as well?  To me it makes sense to have a parent category called "development" and then if I want to view all code or development related items including C#, VB, Java, HTML, C/C++ then all I have to do is click on the new parent category and voila you have everything development related no matter what the sub-category is.

So for the bug:
When the Category List control/widget is rendered it looks at the Category.FullTitle to build the URI. This works fine if you are not a sub-category, like ".net" using the example above, but when rendering the URI for these sub-categories its using the FullTitle which is a concatenation of the parents categories and the title of the sub-category: ie: "development - .net".  This does not work and that link should really just be to the ".net" category. So here is the simple code fix that I used, but take in mind that you could also make it so that "development - .net" works.  I just found a quick and easy fix...

I was working with an image button the other day and for the life of me I couldn't get rid of a runtime error when it went to load the control.  I had a dynamic URL that was something similar to this:

   1:  ImageUrl='../ImageHandler.ashx?File=<%#Eval("Path") %>&MaxSize=<%=PhotoMaxSize %>&ApplyWaterMark=<%=ApplyWatermark %>'

The problem with this is that when the .Net Framework goes to parse this property it first see the "../*" and then goes down a routine to parse the path out, BUT forgets about the fact that I might have something in the URL that needs to be resolved.  It did take me quite a while to figure out what was going on and why the "resolved " path was the same as what was between the quotes. 

My solution was to change it up just a little bit, here is what I ended up with:

   1:  ImageUrl='<%# string.Format("../ImageHandler.ashx?File={0}&MaxSize={1}&ApplyWaterMark={2}", Eval("Path"), PhotoMaxSize, ApplyWatermark) %>' 

The result is the same but I just used a little help from the oh so nice string.Format method. Now because the URL didn't start with "../" or even "~/" it looked and noticed that it needed to resolve what is in the <%#...%>.  On a side note this also applies to the other properties on the control and i would assume that other controls are handled the same way.

I don't know maybe I should have known this before now.

I was just dorking it up on the net today and I found an old topic that I haven't thought about in a long time. 

The Quine: (wikipedia)
In short it is a program in which the output or result of the code is the output of the program itself.  So it really just is a program that's only goal is to output the source code of the program.  Many find it "fun" to see how short of a program they can create, for this reason most will leave out formatting including return/line breaks or anything else that is not required for the program to function.

After a little search on the topic I ran into this website that had an example of quines for a ton of different programming languages, but I didn't see any for C# or for that matter none for any .Net languages.  This is probably because the site is old and has not been updated in a long time.  So as I started to type in google "C# quine" I stopped myself and decided that I would just write my own... so I did.  As you can tell I didn't aim for the shortest possible quine, but this being my first run at this I just decided to keep it simple. Maybe I will redo this making the shortest one that I can.

First I'll show you the program with all the nice formatting that you are used to with Visual Studio, I have removed the formatting because I didn't want to include it in the output of the program.  I did include it at first and it was working just fine but it adds a lot of more junk that is just really not needed.

At work I have a need to change where a virtual direcorty is mapped in IIS.  So being the lazy developer that I am, I wrote a program that helps me take care of this.  Its a simple application that runs in the system tray and allows the remapping of the virtual directory with a couple of clicks.  I have created a page that I will try to keep updated when and if things change with it.  The source code should be posted by the end of the weekend if anyone desires to have a look at it.

This program will create and delete an IIS virtual directory as needed in C#.
