Upgrading EPiServer CMS from version 7 to 7.5 – TinyMCE

Here’s a little note on how to upgrade EPiServer CMS 7.x to EPiServer CMS 7.5.

Bug in property settings for TinyMCE

When everything seemed to work properly after the update I discovered that Edit view occasionally seemed to stop working. The problem occurred when switching from on-page edit to all properties editing and EPiServer seemed to load for a endlessly long time. When I brought up the console window in Firebug I discovered that there where something wrong with the JavaScripts used by EPiServer CMS.

WidgetFactory: Could not resolve one or more widgets
Line 2

My first thought was that I was missing the latest version of the assemblies for the EPiServer UI, but after some investigation, deployment and configuration review I found out that everything seemed to be ok with the binaries and configuration for the web site. Another thing that indicated that everything was correct was that I did not find any direct information among the reported bugs that existed for EPiServer CMS. In other words, it was either an unreported bug or something with my settings.

Since I didn’t find a solution to my problem I let it be a little while, but being a developer means that it is hard to resist to fix broken things, so after a little bit of brainwork I found out that the problem ought to be in TinyMCE and its settings.


The problem where the custom property settings that I used for XHTML properties. By some reason the previous settings made TinyMCE stop working.

I solved the problem by creating a new property setting for the XHTML property in Admin Mode, and set it to be default for all XHTML properties. That solved my problem.

Creating a MenuProvider in EPiServer CMS

EPiServer CMS 6 made it is possible to extend the main navigation that is being displayed in the user interface. Extending the navigation in EPiServer goes under the name Menu Providers and is one of the features in the OnlineCenter concept.

The code below is an example on how a menu provider could be implemented.

public class MySearchProvider : ISearchProvider
    public string Area
        get { return “My Area”; }

    public string Category
        get { return “Content Types”; }

    public IEnumerable<SearchResult> Search(Query query)
        var contentTypeRepo =

        return contentTypeRepo.List()
            .Where(a => a.Name.ToLower().Contains(query.SearchQuery))
            .Select(a => new SearchResult(“”, a.DisplayName, a.Description));

Missing MIME types in IIS

When working with web applications that uses IIS you might see the following error in the console window for your web browser.


Since we are using custom typefaces on our website we need to provide several different fonts to target different devices and platforms. It’s quite common that a client wants to have their own custom font to be used in headings and teasers on their website.

The problem above is because of a missing MIME type mapping in IIS on the web server. The solution is to add the corresponding MIME type extension in the list of supported MIME types. In this case we needed to add the MIME type “application/x-woff” to the extension “.woff”.


Problem solved!

List constraints for all tables in a database

I’ve been working on a project where I’m been responsible for creating a new relational database model. As the database model grew it became quite hard to get a clear picture over naming of constraints among other things, so I decided to create a script that listed all constraints using SQL Server Management Studio.

Below you can see my solution in how to accomplish this. Just remember to rename the MyCustomSchema to your schema name, or omit it if all your tables belong to the dbo schema.


DECLARE @table_name varchar(50)
DECLARE @current_table_name varchar(50)

DECLARE all_tables CURSOR  
FOR SELECT Name from sys.tables

OPEN all_tables

FETCH NEXT FROM all_tables INTO @table_name
SET @current_table_name = 'MyCustomSchema.' + @table_name
EXEC sp_helpconstraint @current_table_name
FETCH NEXT FROM all_tables INTO @table_name

CLOSE all_tables
DEALLOCATE all_tables

Placeholders for images and Lorem ipsum


The following link is great when you need just a dummy image. Just put the link in your image source attribute and alter the width and height.



Twitter has affected the way web sites are being designed today by giving us the Twitter Bootstrap framework. Along with Twitter Bootstrap comes Font Awesome which basically is lots of icons stored in a font.


When you need text to fill up your layout pages there are many options available. Take a look at the links below.

Useful commands when working with ASP.NET in IIS

As a developer I quite often need to e.g. restart IIS, stop or start a web application or list all started/stopped web applications or application pools on my machine. Internet Information Service (IIS) comes with a couple of handy command tools that makes it possible to create small scripts that starts or stops applications.

There are several ways to restart a ASP.NET web application hosted by IIS.

  • Make a minor change in web.config simply by adding a space character somewhere in the whitespace. IIS has listeners that keep track of the configuration files and when a change occur the web application pool for that web application will be restarted.
  • Use IIS to restart the web application or application pool used by the web application.
  • Execute the APPCMD RECYCLE APPPOOL “MyAppName”. This command will recycle the app pool used by the web application with the name MyAppName.


The APPCMD single command line tool can be used to administer sites, application pools, web applications, etc. in IIS. The tool can be found in C:\Windows\System32\inetsrv\ on most Windows machines. Read more about APPCMD here.


A site is the web application that usually has been created in IIS Manager. It is possible to add, delete, configure, start, stop and list the sites hosted by IIS on a machine.

List all web sites hosted by IIS on the current machine:

%systemroot%\system32\inetsrv\APPCMD\APPCMD LIST SITE

Stop and start a specific web site.

%systemroot%\system32\inetsrv\APPCMD\APPCMD STOP SITE “MySite”

%systemroot%\system32\inetsrv\APPCMD\APPCMD START SITE “MySite”

Web applications

A web application is hosted by a site and the name of the web application will either be the name of the site or a part of the URL that leads to the web application. It is possible to add, delete, configure and list web applications hosted by sites in IIS. Read more about the difference between sites and web applications in IIS here.

List all web applications hosted by IIS on the current machine:

%systemroot%\system32\inetsrv\APPCMD\APPCMD LIST APP

Application pools

In IIS application pools are being used to prevent one web application from affecting other web applications. If e.g. a web application experiences problems that web application will not bring down the other applications since it will be hosted by a separate application pool (normally). In older versions of IIS a single process took care of all web sites configured on that machine. The new architecture makes it more easy to maintain web applications and prevent them from affecting each other. It is possible to list, configure, add, delete, start, stop and recycle application pools in IIS on the current machine.

List all application pools on the current machine:

%systemroot%\system32\inetsrv\APPCMD\APPCMD LIST APPPOOL

Recycle an application pool on the current machine:

%systemroot%\system32\inetsrv\APPCMD\APPCMD RECYCLE APPPOOL “MyAppPool”

Worker processes

A worker process is used by application pools to execute the requests sent to the sites or web applications.

List all worker processes used by IIS on the current machine:

%systemroot%\system32\inetsrv\APPCMD\APPCMD LIST WP



IISRESET will stop and restart the web server service including all web applications hosted by IIS.

NOTE: IISRESET should be your last resort if you are working on a machine that is not in production. If you execute this command on a machine that is hosting other web applications (even non ASP.NET web applications hosted by IIS) you WILL restart them as well which might not be desirable.

Examples of usage of IISRESET

Restart the webserver on the current machine:




Get status for the Windows services used by IIS:


Stop the Windows services used by IIS:

Playing with Regular Expressions, part 2 – Find the first word in a sentence

In all the examples below I have used the same sample text (you will see it in the samples). I have used an excellent tool named Expresso to evaluate all expressions in this blog entry.


I want to find the first word in all sentences in a text.


Use the following pattern to find all the first words in a string without any formatting (HTML).



The pattern above will match the following words:

Lorem ipsum dolor sit amet, consectetur adipiscing elit. Ut eu sem nisl.
Nulla elementum consectetur leo nec consequat. Vestibulum quis libero sit amet arcu euismod bibendum a.

Nulla elementum:    1389-89-1443

Praesent a nibh sed augue mollis vehicula.
Vestibulum nisl elit, eleifend a tristique nec, faucibus a sem.


  • The part found in the beginning of the expression, (?:^|\r\n|\.\s+), will determine if the word occur in the beginning of the string or after a previous line in the sentence.
  • The pipe character has the same meaning as the OR operator in code. In the expression above we have three blocks that either one has to be true in order to successfully match the beginning of the sentence.
  • The first part of the expression, (?:^, before the pipe character instructs regex that we only want to match the pattern and not store it in the group of matches. We also states that we are looking at the start of the string by using the caret character.
  • The second part of the expression tries to match carriage return and line feed. We can add more OR cases if we like, e.g. if we only have carriage return or only line feed.
  • The third part after the pipe character, \.\s+, will search for the first word somewhere in a paragraph, e.g. after a previous sentence that ends with a dot and has one or more whitespace characters.
  • The second parenthesis tries to match the first word and will put the word found in a named group named myMatchedWord when a word is successfully matched.
  • When using named groups in regex you have to use the (?<myName>myExpression) construct.
