WPF Converter: CaseConverter

Sytone — Sun, 29 Aug 2010 06:53:35 +0000

Case Converter was made when I wanted the text to display in a WPF UI in upper case. Probably not the best class name, but anyway. To get the code and install read on.

Make any UI string uppercase. Once you have registered the resource and created the class just use the converter in the element you want converted.

Add the following element to the XAML, usually in Window.Resources and ensure that you have registered your namespace for local to the namespace of your application. e.g. xmlns:local=”clr-namespace:ExampleApp”

This is the class, short and sweet.

    public class CaseConverter : IValueConverter
    {
        public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
        {
            string text = value as string;
            if(text != null)
            {
                return text.ToUpper(culture);
            }

            return value;
        }

        public object ConvertBack(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
        {
            return value;
        }
    }

Getting the Central Admin URL for a Farm in SharePoint

I recently needed to get the Url of the CA for a SharePoint farm, after a bit of hunting in the API it was tracked down under the SPAdministrationWebApplication object.

C#

SPAdministrationWebApplication caWebApp = Microsoft.SharePoint.Administration.SPAdministrationWebApplication.Local;
var url = caWebApp.Sites[0].Url;

PowerShell

$caWebApp = [Microsoft.SharePoint.Administration.SPAdministrationWebApplication]::Local
$caWebApp.Sites[0].Url

When is true not true?

Sytone — Mon, 31 May 2010 10:30:17 +0000

When you look at true stored in the .Net framework.

While playing with Pex I found out a interesting fact that the bool is a byte in the MSIL. Which means that a bool could be euqal to anything on the byte range… Now this would require you to go out of your way and create unsafe code blocks to do this. Why you would do this… No ideas

Its marked as a no-fix which is not supprising as I would not fix it either becase as they say, if you know about this and you use it then you are on your own..

Getting a Outlook MailItem from a Ribbon Event

You may find this code block handy:

        ///
        /// Gets the mail item selected in the explorer view if one is selected or instance if that is the view active.
        ///
        ///
The  instance containing the event data.
        /// A Outlook.MailItem for the mail being viewed.
        private Outlook.MailItem GetMailItem(RibbonControlEventArgs e)
        {
            // Check to see if a item is select in explorer or we are in inspector.
            if (e.Control.Context is Outlook.Inspector)
            {
                Outlook.Inspector inspector = (Outlook.Inspector)e.Control.Context;

                if (inspector.CurrentItem is Outlook.MailItem)
                {
                    return inspector.CurrentItem as Outlook.MailItem;
                }
            }

            if (e.Control.Context is Outlook.Explorer)
            {
                Outlook.Explorer explorer = (Outlook.Explorer)e.Control.Context;

                Outlook.Selection selectedItems = explorer.Selection;
                if (selectedItems.Count != 1)
                {
                    return null;
                }

                if (selectedItems[1] is Outlook.MailItem)
                {
                    return selectedItems[1] as Outlook.MailItem;
                }
            }

            return null;
        }
