Examples

The following example shows how to declare a JumpTask in markup. The JumpTask opens a text file named readme.txt in the Notepad application.

<JumpTask Title="Read Me" 
          Description="Open readme.txt in Notepad." 
          ApplicationPath="C:\Windows\notepad.exe"
          IconResourcePath="C:\Windows\System32\imageres.dll"
          IconResourceIndex="14"
          WorkingDirectory="C:\Users\Public\Documents"
          Arguments="readme.txt"/>

The following example shows how to configure a JumpTask in code. The JumpTask opens the Calculator application.

// Configure a new JumpTask.
JumpTask jumpTask1 = new JumpTask();
// Get the path to Calculator and set the JumpTask properties.
jumpTask1.ApplicationPath = Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.SystemX86), "calc.exe");
jumpTask1.IconResourcePath = Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.SystemX86), "calc.exe");
jumpTask1.Title = "Calculator";
jumpTask1.Description = "Open Calculator.";
jumpTask1.CustomCategory = "User Added Tasks";

Remarks

A JumpTask can be thought of as a shortcut to an application. You specify the path to the executable file by setting the ApplicationPath property. If the ApplicationPath is not set, the path of the current running process is implied. You can optionally specify Arguments to pass to the application at startup.

You can set basic display properties, such as Title, Description, and IconResourcePath to specify the appearance of the task in the Jump List. An icon used with a JumpTask must be available as a native resource. If multiple icon resources are available in a DLL or executable file, you specify the one to use by indicating an offset in the IconResourceIndex property.

By default, a JumpTask will be placed in the Tasks category of the Jump List. You can specify custom grouping of tasks by setting the CustomCategory property.

You can visually separate items in a Jump List by creating a JumpTask that does not have a Title and CustomCategory specified. This empty JumpTask will be displayed as a horizontal line in the Jump List. In this case, other properties can be set, but they will not have any effect.
