Hi,

I got this error while opening CRM 4 !

The solution was to run the following command

ServiceModelReg.exe –i

which could be found at

C:Windows\Microsoft.NET\Framework\v3.0\Windows Communication Foundation.

Followed by an IISReset.

However in few cases to resolve it, it requires reinstallation of IIS.

ServiceModel Registration tool with -i option

Registers this version of WCF and update scriptmaps at the Internet Information Services (IIS) metabase root and for all scriptmaps under the root. Existing scriptmaps of lower versions are upgraded to this version.

Bye.

We developed a web part showing the folders hierarchy using tree view control. However the folders were not getting displayed in the tree view node in the order they are visible inside the document library i.e. sorted on name.

Creating a tree view

http://www.davehunter.co.uk/Blog/Lists/Posts/Post.aspx?List=f0e16a1a-6fa9-4130-bcab-baeb97ccc4ff&ID=115

So finally used the following code to sort the folders

List<SPFolder> folderList = new List<SPFolder>();

foreach (SPFolder myFolder in folder.SubFolders){

folderList.Add(myFolder);

}

folderList.Sort(delegate(SPFolder p1, SPFolder p2) { return p1.Name.CompareTo(p2.Name); });

Hi,

Yesterday while browsing encountered the following site

The site has got nice reference material written by experts.

Do check out this site !!

Bye …

To user hyperlink in WPF application we could do something like this

<TextBlock>

<Hyperlink NavigateUri=”http://www.google.co.in”>

            Click here

</Hyperlink>

</TextBlock>

However the NavigateUri works only if we are placing the hyperlink within a page. To use it within a windows-based application we need to hanlde the RequestNavigate event and write the code ourselves.

Something like this

<TextBlock>           

<Hyperlink NavigateUri=”http://www.google.co.in” RequestNavigate=”Hyperlink_RequestNavigate”>

 Click here

</Hyperlink>            

</TextBlock>

private void Hyperlink_RequestNavigate(object sender, RequestNavigateEventArgs e)

  {

            Process.Start(new ProcessStartInfo(e.Uri.AbsoluteUri));

            e.Handled = true;

  }

While using hyperlink we could also provide handler for Application.NavigationFailed event in case if navigation fails.

That’s it ….

Suppose we  want to create a custom config section in this following manner

<queryTypes>

    <queryType name=“qt1“ value=“qt1 value“></queryType>

    <queryType name=“qt2“ value=“qt2 value“></queryType>

</queryTypes>

For implementing the above custom section we need to first define a class inheriting from ConfigurationSection class

Add reference to System.Configuration dll.

Create a new config section class in the following manner

    // implement ConfiguraionSection class

    class QueryTypesSection : ConfigurationSection

    {

        public QueryTypesSection()

        {

        }

        [ConfigurationProperty("", IsDefaultCollection = true)]

        public QueryTypesCollection QueryTypes

        {

            get

            {

                return (QueryTypesCollection)base[""];

            }

        }

    }

    // Represents a configuration element containing a collection of child elements   

    public sealed class QueryTypesCollection : ConfigurationElementCollection

    {

        protected override ConfigurationElement CreateNewElement()

        {

            return new QueryTypeElement();

        }

        protected override object GetElementKey(ConfigurationElement element)

        {

            return ((QueryTypeElement)element).Name;

        }

        public override ConfigurationElementCollectionType CollectionType

        {

            get

            {

                return ConfigurationElementCollectionType.BasicMap;

            }

        }

        protected override string ElementName

        {

            get

            {

                return “queryType”;

            }

        }

    }

    // Defining QueryTypeElement with name and value attribute

    public sealed class QueryTypeElement : ConfigurationElement

    {

        // defining name attribute

        [ConfigurationProperty("name", IsRequired = true)]

        public string Name

        {

            get

            {

                return (string)this ["name"];

            }

            set

            {

                this["name"] = value;

            }

        }

        // defining value attribute

        [ConfigurationProperty("value", IsRequired = true)]

        public string Value

        {

            get

            {

                return (string)this["value"];

            }

            set

            {

                this["value"] = value;

            }

        }

    }

Now to register your custom section do the following

<configSections>

<section name=“queryTypes“ type=“namespace.QueryTypesSection, namespace “ />

</configSections>

And to use it within the application

  QueryTypesSection queryTypeSection = (QueryTypesSection)ConfigurationManager.GetSection(“queryTypes”);

            QueryTypesCollection  queryTypeCollection = queryTypeSection.QueryTypes;

            foreach (QueryTypeElement se in queryTypeCollection)

            {

                string name=se.Name;

                string value = se.Value;

            }

That’s it…
