Another successful Multipack meet

So Saturday was another chance to meet up with all the Multipack guys in a recently restructured Multipack -same place (The Old Joint Stock in Birmingham), same time (second Saturday of the month). Personally I think it's a good move as the numbers were well up on normal with lots of lovely new Multipackers (I'm no longer the n00bie ;)) from all sorts of interesting backgrounds.

It's great that Multipack is slowly becoming more recognised; at Saturday's meet for example Underscore veteran Darren Beale trekked up from Worcester which was nice as I could finally put a face to the name. Hopefully over the next few months, with a little more self-publication and this easy to remember location/date we'll get more new members.

If you're not sure about coming along just yet, check out the website www.multipack.co.uk and get to know a few of the guys, alternatively there's a mailing list -http://groups.google.com/group/multipack and IRC channel: IRC: irc.freenode.net, 6667, #multipack so plenty of ways to join in.

The new "The Site Doctor" website finally gets online!

Somewhat behind the original schedule we've finally launched the new company website!

There's still more refining to be done to it and there are a few errors but it's far better than the old site :)

Visit the new The Site Doctor website at www.thesitedoctor.co.uk -new customer quotes and portfolio items coming soon!

We've got some wicked new branding designs to share shortly but until it's all published it's all very hush hush I'm afraid ;)

Random images in Umbraco

Following on from a recent post of mine about how to setup changeable headers using the media picker in Umbraco a new site I have been working on required something a little extra -they wanted the headers to simply be chosen at random. from a given media folder.

First, create  a new (blank) XSLT file and add the following:

Random header images XSLT

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE xsl:Stylesheet [ <!ENTITY nbsp " "> ]>

<...>

<xsl:stylesheet 
    version="1.0" 
    xmlns:xsl="http://www.w3.org/1999/XSL/Transform" 
    xmlns:msxml="urn:schemas-microsoft-com:xslt"
    xmlns:umbraco.library="urn:umbraco.library"
    xmlns:msxsl="urn:schemas-microsoft-com:xslt"
    xmlns:math="urn:schemas-hizi-nl:math"
    xmlns:Exslt.ExsltStrings="urn:Exslt.ExsltStrings"
    xmlns:Exslt.ExsltMath="urn:Exslt.ExsltMath"
    exclude-result-prefixes="msxml Exslt.ExsltMath Exslt.ExsltStrings math umbraco.library">

<xsl:output method="xml" omit-xml-declaration="yes"/>

<xsl:param name="currentPage"/>

<msxml:script language="JavaScript" implements-prefix="math">
function random(numDie,numMax,numMin){
if (numMin==null){numMin=1;}
var sum=0;
for (var index=0;index&lt;numDie;index++){ 
sum+=Math.floor(Math.random()*(numMax-numMin) + numMin);
}
return "" + sum;
}
function floorme(numFloor){
return "" + Math.floor(numFloor);
}
</msxml:script>

<xsl:variable name="StartNode" select="/macro/StartNode/node/@id" />
<xsl:variable name="parent" select="umbraco.library:GetMedia($StartNode, 'false')" /> 
<xsl:variable name="random" select="math:random(1, count($parent/node)+1, 1)"/>

<xsl:template match="/">

    <xsl:for-each select="$parent/node">
        <xsl:if test="position()=$random">
            <xsl:if test="./data [@alias = 'umbracoExtension'] = 'gif' or ./data [@alias = 'umbracoExtension'] = 'jpg' or ./data [@alias = 'umbracoExtension'] = 'jpeg' or ./data [@alias = 'umbracoExtension'] = 'png'">
                <style type="text/css">
                #header{
                    background-image: url(<xsl:value-of select="./data [@alias = 'umbracoFile']"/>);
                }
                </style>
            </xsl:if>
        </xsl:if>
    </xsl:for-each>
</xsl:template>

</xsl:stylesheet>

What this does is it uses the StartNode (a media folder) passed in from the macro to loop through any valid files (in this case jpg/gif/png and pull out the image if it's valid. I was thinking about replacing the for-each loop and simply using the index but I'm not sure if there would be any performance improvement except for if there were a lot of header images in the folder.

You'll then need to create a new macro and add a parameter with the name "StartNode" and select "mediaCurrent" as the Type. That's it :)

Fantastic new -and cheap domain name registrars

After our recent issues with Fasthosts (or as they are now fondly referred to in the office - Farcehosts) I have made the conscious decision to move away from them completely over the forthcoming months (probably years). We no longer have any clients on their hosting platform but we still have circa 300 domain names registered through various accounts through their sister company UKReg.

Due to the authority's charges, we can't just transfer all these domains away as it'd cost us a fortune (and possibly one we can't recoup) so I'm going to do it as they expire. In our search to find an alternative provider someone suggested we check out the new kid on the block - Heart Internet. According to those in the know on Underscore they are a bunch of guys who used to work at 1&1 and decided they could do it better.

So far I've found their service to be great -and value wise they're cheaper than most providers which is a bonus. As with most of the providers these days it's all managed through their easy to use online control panel which is pretty straight forward. If you're on the lookout for great value or cheap domain names give Heart Internet a look.

BTW if you're wondering where Heart Internet's .co.uk domain names from 9p is, check under the transfer fees. Still £2.59 is a great price for any .co.uk!

How to: Remove users from the ASP.Net membership database

I'm sure I've blogged about this in the past -or perhaps it's just in my "to blog about list" but I thought I would share this little ditty on the Sunday night.

If you ever need to delete a user from your ASP.Net Membership database this is a really useful SQL script to do just that (I often find that the ASP.Net web administration tool throws a SQL Exception while trying to delete a user).

To use the code to delete a user from the ASP.Net membership database simple identify the Guid of the user and enter it where I've written 'THE GUID OF THE USER HERE' and hit go :)

USE ASPNet
GO

DECLARE @UserId uniqueidentifier
SET @UserId = 'THE GUID OF THE USER HERE'

DELETE FROM aspnet_Profile WHERE UserID = @UserId
DELETE FROM aspnet_UsersInRoles WHERE UserID = @UserId
DELETE FROM aspnet_PersonalizationPerUser WHERE UserID = @UserId
DELETE FROM dbo.aspnet_Membership WHERE UserID = @UserId
DELETE FROM aspnet_users WHERE UserID = @UserId

The message I was referring to above usually looks something like the following:

Msg 547, Level 16, State 0, Line 9
The DELETE statement conflicted with the REFERENCE constraint "FK__aspnet_Us__UserI__17036CC0". The conflict occurred in database "ASPNetMemberships", table "dbo.aspnet_UsersInRoles", column 'UserId'.
The statement has been terminated.

I've not looked into why it's happening (I expect it's something to do with an incorrect install on my behalf) but I'm sure there's a solution for it. I know there are a couple of built in SQL scripts i.e. aspnet_Users_DeleteUser but they required more params to get working ;)

Registration opens for Visual Studio 2008 launch events... but the UK doesn't exist (yet!)

This mad me smile,  when surfing around at lunch I stumbled across www.heroeshappenhere.com -Microsoft's Visual Studio 2008 launch site. I got all giddy with excitement, downloaded the latest version of Silverlight and woohoo -a registration link! Finally!

Sadly though, you can only register for the LA event at the moment. Check the "Outside of the US" drop down though, it'll make you smile (or at least it did me) -notice anyone missing? (Other than France that is :P)

Changeable headers using the media picker

A project we’re currently working on needs to have interchangeable header images. The theory is to set the header image on the parent page and then unless a template is specified for the page, it should use one of it’s ancestor’s.

Umbraco as a nice control called a “Media Picker” which I felt was perfect for the job as it meant you could easily share header images across the site and it also made sense from a user perspective to have a “Header Images” folder to choose from. The issue from my point of view was how to traverse up the tree until it found a header image to use. Imagine the following site map:

-Home
     -Products
          -Category
               -Product details (Custom header image)

If you’re on the products/category page it should display the header image from Home but when you’re on the product details page it needs to show the specified header image.

So how do you do it? It turns out it’s (fairly) simple using XSLT. The first issue I ran into was getting the URL of the media file from the media picker control, Umbraco offers a useful function to do this for you (well almost!). Using the function umbraco.library:GetMedia you are able to get the details on the file based on the media item id but it includes everything so you then need to use a little XSLT to select the attribute “umbracoFile”:

That should give you something along the lines of “/imgs/somefolder/somefile.jpg”

Now how can you traverse up the tree to get the data? Thanks to Morten Bock/Casey Neehouse for helping me understand this XSLT, but the following code should give you the URL of the nearest media item in the tree:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE xsl:Stylesheet [ <!ENTITY nbsp " "> ]>

<...>

<xsl:stylesheet 
        version="1.0" 
        xmlns:xsl="http://www.w3.org/1999/XSL/Transform" 
        xmlns:msxml="urn:schemas-microsoft-com:xslt"
        xmlns:umbraco.library="urn:umbraco.library"
        exclude-result-prefixes="msxml umbraco.library">

<xsl:output method="xml" omit-xml-declaration="yes" />

<xsl:param name="currentPage"/>

<xsl:template match="/">
    <xsl:choose>
        <xsl:when test="$currentPage/ancestor-or-self::node [string(data[@alias='pageBanner'])!=''][1] /data[@alias='pageBanner'] != ''">
            <xsl:value-of select="umbraco.library:GetMedia($currentPage/ancestor-or-self::node [data[@alias='pageBanner']!=''][1] /data[@alias='pageBanner'],'false')/data [@alias = 'umbracoFile']"/>  
        </xsl:when>
        <xsl:otherwise>
            <!-- The URL of the default banner just incase the user removes the homepage banner (would be better as a parameter) -->
        </xsl:otherwise>
    </xsl:choose>
</xsl:template>

</xsl:stylesheet>

Then add a macro to your project and you’re done :). You can see it in action on the new Lucy Switchgear website if you're interested, it's currently being written so it's bound to be a little rough around the edges but do let me know what you think. Our remit was to improve the CMS they had in place making it easier to manage the site and also sort out a few major issues from a SEO perspective. Although altering the design wasn’t part of the initial brief I think you’ll agree the facelift we’ve given the site is for the better (even if it’s just from a usability point of view).

Naming conventions for Umbraco

Having only recently started to use Umbraco I've taken a couple of days to familiarise myself with the way it works and try and get a few best practices in place, I expect these will be updated over time but you've got to start somewhere ;)

As with any code, I think it's very important to follow a consistent naming convention -whether it's the same one everyone else follows or not, you need to be able to pickup code you wrote months/years/decades ago and still understand it. Your styles will no doubt change over the years but you get the idea.

I've chosen to follow the following "style":

• Document Types: Lowercase the first letter of the aliases followed by capitals for the new words (similar to Hungarian Notation). Use descriptive names i.e. Home Page for the document type as it'll be client facing. Suffix with "Page" if it is a page document type (as opposed to i.e. a screen shot)
• Templates: If the template is specifically for a document type, use the same name for the template, if it relates to multiple document types name it logically i.e. "Master Template" or "Left Menu"
• Macros: Prefix the macro alias with uppercase TSD to avoid conflicts with other macros. Prefix the name with [Source of the macro] i.e. [XSLT] or [User Control]. This is something I picked up from the sample package created by Warren Buckley that I think makes it easier to understand what's going on
• XSLT Files: Prefix the name with the site's abbreviation i.e. for www.thesitedoctor.co.uk it would be TSD or for www.wineandhampergifts.co.uk WAHG if it's a site specific XSLT file otherwise name conventionally i.e. CamelCase

Fasthosts fail to amaze again

I don't know if any of my readers are familiar with Fasthosts' recent security problems that hit the press a couple of weeks ago but I couldn't help but laugh at a conversation I had with them the other day. Baring in mind they had a breach in their security which meant that all passwords had to be reset I was astonished to get this email about an FTP login issue.

Is it just me or is that a little nuts asking a user to send their username and password in clear text just after a major breach in security? I thought my response was very measured:

What have I been up to?

It's been rather quiet on my blog recently, if you're wondering why (and don't chat to me on/off-line) I thought I would share with you what we've been working on recently.

For the past month or so The Site Doctor has been developing a new web site (www.wineandhampergifts.co.uk) for Porter and Woodman Gifts Ltd - a local company that produces personalised corporate hampers and gifts. It's been quite a challenge as they have a rather unusual ordering system that allows multiple recipients/addresses multiple items. Looking at it now, it's not so complicated but the delivery charge calculations and initial specs took a while to fully grasp. It's been really enjoyable.

I'll probably cover aspects of the site over the forthcoming months but there are a few really nice features to the Wine and Hamper Gifts site (or at least I think so), some of which the end user will never know about such as the use of generics to calculate the address/recipient/gift variations) and those that they may -for instance the use of the JavaScript¹ Zoom function on the product details page (courtesy of LuckyZoom), also the design created by our excellent designer Gareth Brown all adds up to what has to be one of the best sites I've developed to date.

¹ Yes, I did just say I've integrated some JavaScript into the site ;)

I doubt most of my readers are interested on the in's and out's of the project itself but from an SEO perspective, I for one am expecting pretty decent results. We opted to use the URL Rewriting ISAPI from Helicon this time round over our usual IISMods URL Rewriting ISAPI as for some reason the IISMods site has been offline for a while (and checking now has been converted into a very weird site).

Another aspect that some people may be unaware of is that the majority of the Wine and Hamper Gifts site operates the same without JavaScript as it does with JavaScript, this is important not only for screen readers but also search engines. There is only one area of the Wine and Hamper Gifts site that I'm aware of that doesn't operate without JavaScript and that is the "Personalise this gift" link on the cart page that allows the user to either edit the existing message or add one that doesn't already exist, that's because it uses a LinkButton, but I may find a way around that later.

Other features that I really like are little things like the way the drop down lists on the left hand menu are created -they're not actually drop down lists but unordered lists that are then manipulated using JavaScript, I think the JavaScript could do with a little tweaking but the result is superb. The Wine and Hamper Gifts site also creates a PDF receipt for the user which is emailed to them, this is something I've been meaning to look into for some time but haven't had the chance, luckily while I was developing the site, Sean Ronan posted to the MsWebDev list about an ASP.Net PDF library iTextSharp (a port from a Java library) which, despite a few oddities from the POV of the Java port does exactly what I wanted. The library is pretty easy to use once you get your head around it and certainly produces some nice results.

There's still more work that's needed to finalise the content and various aspects of the Wine and Hamper Gifts website but if you have a chance, check out the new Porter and Woodman Gifts Ltd Wine and Hamper Gifts website and leave a comment here letting me know what you think :D

Oh, and they've given us a pretty high target to get before Christmas so if you're thinking about treating your customers to a personalised corporate hamper or gift give a little thought to using www.wineandhampergifts.co.uk

The Controls collection cannot be modified because the control contains code blocks

Another day, another issue ;)

This had me going around in circles for a while until I realised what it was, if you're getting this error you can bet your bottom dollar that you have <%= %> somewhere in your page's header -furthermore I'd hazard a guess that you've got it in some JavaScript to reference an ASP.Net control on the page- and then you're trying to add a control to the header programmatically (or a custom control from someone like Telerik is trying to). Am I right¹?

¹ I'm not allowed to ask you to so I won't, but if I was right, then spend that bottom dollar clicking on one of the Google Ads :P

I can't tell you exactly why this occurs but my understanding of it is that ASP.Net can't re-create the header if it has Response.Write somewhere in the header (<%=) -most likely due to when the header is created it's not available (will look into it). No doubt you want to know the fix?

The Fix
The fix is simple, remove the inline code blocks and JavaScript and move it to your code behind i.e.:

string _manageSearch = String.Format(@'...'"lblFindAGift"");

string _manageSearch = String.Format( @" 
        function ManageSearch(){{
                var lbl = document.getElementById(""lblFindAGift"");
                var txt = document.getElementById(""{0}"");
                var btn = document.getElementById(""{1}"");

                .Do Something with it..

        }}",
        txtSearch.ClientID);

this.Page.ClientScript.RegisterClientScriptBlock(this.GetType(), "ManageSearch", _manageSearch, true);

Remember: You need to escape the curly brackets otherwise you will get a "String.Format- Exception of type System.Web.HttpUnhandledException was thrown"

Update: Thanks to Julian Voelcker for sending me this alternative "fix" for the problem, can't say I like it though ;) basically instead of using <%= ... %> you would write the databinding expression of: <%# ... %>
