Handler “ExtensionlessUrlHandler-Integrated-4.0” has a bad module “ManagedPipelineHandler” in its module list

How to fix the error 'Handler “ExtensionlessUrlHandler-Integrated-4.0” has a bad module “ManagedPipelineHandler” in its module list'.

This error occurred when I moved my moved my ASP.NET 4.5 from an old Windows 7 machine to a brand new Windows 8 machine running IIS 8.

I was thinking I was in need of an aspnet_regiis -I but this threw back a message at me saying "Start installing ASP.NET (4.0.30319.17929). This option is not supported on this version of the operating system. Administrators should instead install/uninstall ASP.NET 4.5 with IIS8 using the "Turn Windows Features On/Off" dialog, the Server Manager management tool, or the dism.exe command line tool. For more details please see http://go.microsoft.com/fwlink/?LinkID=216771. Finished installing ASP.NET (4.0.30319.17929)."

So I turned to turning windows features on/off (Win+X then hit F). I had already turned IIS on but then I had found I hadn't done enough.

Previously when I had turned IIS on I had left it with the default but actually I needed more to get ASP.NET 4.5 to run. You need to go to:

1. Internet Information Services
2. World Wide Web Services
3. Application Development Features
4. Then check ASP.NET 4.5

This will select a few other bits for you and you should be good to go.

Finding Outlook Web Access (OWA) URL from Outlook 2010

I was struggling to find out my Outlook webmail address from Outlook 2010 on my machine so that I can access my work email from home or on my mobile. The OWA URL is hidden quite deep into Outlook 2010 so I have written down the location of the URL so I can remember for next time.

It is rather hidden away, probably because it is assumed you would just ask IT instead of finding out for yourself but that isn't like you is it. That's why you're here!

Finding your web mail address in Outlook 2010

1. Click the File tab near the top left
2. Click the Info tab
3. Click the big "Account Settings" button and then "Account Settings" again on the pop out menu
4. On E-mail tab ensure your address is selected and click the "Change..." button just above it
5. Click the "More Settings ..." button at the bottom
6. Go to the Connection tab and click "Exchange Proxy Settings..." button at the bottom
7. It is the first URL on this window. Something like https://mail.mydomain.com

Web forms button click event not firing in IE

There are probably many reasons why a button would not fire in an ASP.NET web forms application. Some can be fixed with deleting cookies and history, some are to do with when the event is registered. I found a new one though.

In my scenario I had a text box that was submitted with a button next to it. We didn't want to display the button though but instead wanted the form submitted with a click of the Enter button. The button was therefore wrapped in a display:none span, like this:

<input type="text" id="txtInput" onchange="btnGo_Click" runat="server"/>
<asp:Button style="display:none;" runat="server" OnClick="btnGo_Click" />
<asp:Label ID="lblOutput" runat="server" />

It turns out that this worked just fine in Chrome and Firefox but not in IE9. This was because not all browsers post data that is hidden with CSS. Security possibly? You could see this by looking at the request in Fiddler. There was no value for the button field in IE but there was for the others.

How to submit a form by clicking Enter and hiding the button

The best way I can think of is to hide the button without hiding it... How? You can push it miles of the page to hide the button with some CSS like this:

<input type="text" id="txtInput" onchange="btnGo_Click" runat="server"/>
<asp:Button style="position:absolute;left:-9999px;" runat="server" OnClick="btnGo_Click" />
<asp:Label ID="lblOutput" runat="server" />

This will put the button miles off to the left never to be seen by the user.

Add rel="nofollow" to all external links with one line of jQuery

You may want to change all external links on a page to do something different such as add a target="_blank" to each one or add rel="nofollow" to every external link. This post will show you how this can be done in one line of jQuery!

SEO SEO SEO... How tiresome a concept... Anyway, people make their living with it apparently and while that is the case I get all kinds of weird requirements like this. This time I had to add rel="nofollow" to all external links for latest whim of an SEO consultant.

Since SEO requirements seem to chop and change fairly unpredictably I wanted to add rel="nofollow" to all external links in the quickest and least interfering way possible. I managed it with one line of jQuery so that is fairly innocuous and I can just remove it if it needs to be undone at some point. This can be used to add target="blank" to also.

Add rel="nofollow" to all external links

$("div.content a[href^='http']:not([href*='mysite.co.uk'])").attr("rel", "follow");

Add target="_blank" to all external links

$("div.content a[href^='http']:not([href*='mysite.co.uk'])").attr("target", "_blank");

Hope this helps you spend as little time on this as possible :)

Update:

I did some reasearch into whether adding a nofollow in this way will work on Google and came to the conclusion that it probably wont. Colin Asquith commented similar thoughts. So this should probably be considered if using this for adding rel="nofollow" to links but technically this is a good way of going about it or anything similar like adding target="_blank" for example.
