Delete a project from Team Foundation Service

Since the "Team Foundation Service" hasn't an administrative console, it's not possible to use it to delete a hosted project.

So to delete a team project from one Team Foundation Service collection you have to use the "tfsdeleteproject.exe" command line tool:

tfsdeleteproject /collection:https://<your collection>.VisualStudio.com/DefaultCollection <"Project Name">

GridView Scroll to a desired group in a Windows Store App

By default, in a Windows Store App, the focus in a GridView is given to the element "0" of the group "0". But what if you wanto to change this behaviour and make it "open" to another element?

To do it, you have to manage the  itemGridView_Loaded event and use the CollectionView:

In XAML:

<GridView

    x:Name="itemGridView"

    AutomationProperties.AutomationId="ItemGridView"

    AutomationProperties.Name="Grouped Items"

    Grid.RowSpan="2"

    Padding="116,137,40,46"

    ItemsSource="{Binding Source={StaticResource groupedItemsViewSource}}"

    ItemTemplate="{StaticResource Standard250x250ItemTemplate}"

    SelectionMode="None"

    IsSwipeEnabled="false"

    IsItemClickEnabled="True"

    ItemClick="ItemView_ItemClick"

    Loaded="itemGridView_Loaded">

Incode-behind:

private bool firstTime = true;
        
   private void itemGridView_Loaded(object sender, RoutedEventArgs e)
   {
        ICollectionView view;
        ICollectionViewGroup myGroup;
        Data.MyDataType myItem;
 
        if (!this.firstTime) return; else firstTime = false;
        view = itemGridView.ItemsSource as ICollectionView;
        view.CurrentChanged += view_CurrentChanged;
        int groupIndex = 2; // an integer value between 0 and # of items in the groups collection
        myGroup = view.CollectionGroups[groupIndex] as ICollectionViewGroup;
        myItem = recipeGroup.GroupItems[0] as Data.MyDataType;
        view.MoveCurrentTo(myItem);
    }
     
    private void view_CurrentChanged(object sender, object e)
    {
        ICollectionView view;
        Data.MyDataType  myItem;
         
        view = itemGridView.ItemsSource as ICollectionView;
        view.CurrentChanged -= view_CurrentChanged;
        myItem = view.CurrentItem as Data.MyDataType;
        itemGridView.ScrollIntoView(view.CurrentItem, ScrollIntoViewAlignment.Leading);
    }

Privacy Policy in Charm Bar: the easiest way

When you make a Windows Store App, if it uses any Network connection, you have to specify your Privacy Settings in both Store page and Charm Bar.

But how to do it? What's the simplest way?

So, here's the answers.

Do the following in your App.xaml.cs:

1) Add the namespaces

using Windows.UI.ApplicationSettings;
using Windows.UI.Popups;

2) Add the handler during app initialization (into OnLaunched())

SettingsPane.GetForCurrentView().CommandsRequested += SettingCharmManager_CommandsRequested;

3) Add my handler that shows the privacy text

private void SettingCharmManager_CommandsRequested(SettingsPane sender, SettingsPaneCommandsRequestedEventArgs args)
{

    args.Request.ApplicationCommands.Add(new SettingsCommand("privacypolicy", "Privacy policy", OpenPrivacyPolicy));

}

4) Add OpenPrivacyPolicy method

private async void OpenPrivacyPolicy(IUICommand command)

{

    Uri uri = new Uri("http://my_website/my_privacy.html");
    await Windows.System.Launcher.LaunchUriAsync(uri);

}

SharePoint 2013: The username is invalid. The account must be a valid domain account

When configuring SharePoint 2013 in “Complete” mode you get a “The username is invalid. The account mist be a valid domain account” when using a local account to configure the farm…

Out of the box SharePoint only supports “Stand-alone” mode for non domain environments, but this forces you to use SQL Server 2008 R2 Express Edition which is most cases is unacceptable.

The solution is to use a PowerShell command to create the initial configuration of the farm with a local account:

1) Start the SharePoint PowerShell (not the "standard" one)

2) Run “New-SPConfigurationDatabase” from the command line and follow the instructions. This will create the farm and configure the necessary accounts.

3) Rerun the Configuration wizard. After it finishes start the Config Wizard (interactive or not) and configure your server with all components
