[Tutorial] Windows 7 JumpLists

Hi Coders !

Windows 7 comes with a cool feature of Jump Lists.

When we right click an application on taskbar, a list appears showing the recently opened items and pinned items for this application. That list is known as Jump List.

.Net 4.0 comes with handy Classes known as JumpTask and JumpList. By using these classes we can add custom items under custom categories to our application.


Here we go:
Works only in .NET Framework 4.0 and on Microsoft Windows 7 OS

Add the reference to the following 2 .NET assemblies:

1: Presentation Framework
2: Windows Base

Then on the Main Form of the application, import the following namespace:
Now double click the Main Form or in the loading event of your main form, add the following code:
Explaination:
Dim newTask As New JumpTask
Creates a new item for our list.

newTask.Title = "Visual Basic .NET"
Set the title of the item.

newTask.Description= "Visit MPGH for VB.NET Tutorials."
Set the description of the item. This will be shown when the user will move the mouse over the item.

newTask.Arguments = "/update...or what ever you want to do on clicking..."
Set the arguments for the item. Set this to perform the operation on clicking the item.

newTask.CustomCategory = "MPGH"
This will set the category for the item. By default, we see "Frequent", "Recent" and "Pinned" Items list in Windows 7. But we can have our own category and you can name it whatever you want. In this case I chose "MPGH".

Dim newList As New JumpList
Creates the list. We will add items in this list.

newList.JumpItems.Add(newTask)
Add the item to the list.

Dim app As New System.Windows.Application
We need to give a reference to our application so that Windows can recognize our application and can add the custom list and items to it. This will create a new recognizable instance of our application.

JumpList.SetJumpList(app, newList)
Finally call the JumpList method directly and add the list to the application. It takes two parameters. In the first we will refer our application instance. And in the second we will add the list.

Note: You can also turn on Frequent list and Recent list by using:
newList.ShowFrequentCategory
And
newList.ShowRecentCategory

You can now test the list by right clicking the application in the task bar.



Credits: This tutorial was originally written by Christian Mosers for WPF in C#. I converted the code to Windows Forms Application. e.g; Created the application instance and references. Also there's no original explaination of the code.

thanks for sharing

meh, not much use for it right now, Windows 7 is still a new concept with a few good API's , don't get me wrong , it's a great share, but in releases you want them to be as productive as possible, adding this api will crash your application on non windows 7 machines, making your "Found Users" less then your "Target Users"

Windows Offers whats called a "API Code Pack" Best bet is to get the Windowx Xp Codepack , windows vista codepack and Windows 7 codepack , then compare each API looking for great API's that will enhance your project but are static throughout each of the major windows versions

(IMO)
It is bad practice to limit usability to a single OS.

yes there is code to check the version of windows which you can use to flag (on , Off) this feature which ease, but I still feel it is bad practice

Agree. Why shouldn't they. What are the experts doing to urge them to convert ?? I mean we should show them some power, ease and benefits of the new tech like WPF. Benefits like 2 hours work completed in 1 hour, etc...Otherwise they will get stick to the old one !!

Surely we don't have but we can suggest, there's no restriction to that. When I open Youtube / any other video sharing site, I see no computer with out Vista/7. People will buy such stuff if they'll know its uses. No one comes out and tells the advantages. For example we heard that vista is resource sucker / not compatible etc... But we forgot its advantages until we used it.

Haha, IMO you should do Next, people here follow you. I follow you. People should be aware of the new tech. It's their choice whether to use it or not. But experts here should write some new tech stuff.

If I get time, I will do the introductory series of WPF.

Agree, but don't you think Themes are unable to copy Aero-Desktop and Flip3D effect which those users show off very proudly !! ?

To give a test try I'll try an article and the response should make the things crystal clear.

Looks nice thanks!

But i have a request/question;

You know when you right click a file (lets say a .txt) it says open with -> or edit and all that... How do you make your program recognize what is being opened and load it into like a textbox. I have the right values in the registry, it opens my program, but how do i take the contents of the .txt and add to my textbox on my form ;D

Ty ~ a PM is fine or NG will prop tut it?

Lol count on NextGen to answer every single question/query that comes up...
