Creating your own windows with JScript

When working with JScript you might want to open a new window. There are a few different ways that this can be done and today I’ll share how to create a new window that is visible in the taskbar and how to open a modal window. Modal means that you cannot access any other Smart Office functionality such as the QuickNote widget or data in a form as the modal window is the only currently active window placed above all other windows. A modal window is a graphical control element subordinate to an application’s main window which creates a mode where the main window can’t be used. The modal window is a child window that requires users to interact with it before it can return to operating the parent application, thus preventing the workflow on the application main window. This is great for some cases but can also be frustrating.


Some of the concepts when working with windows in Smart Office is IInstanceHost – which represents the contract to an application host window. Then if a window is visible in the TaskBar it has to have a Runner – a handle to a task running on the Canvas. A Task is an item that can be launched on the Canvas. A task can only be launched if there is a registered application that supports the task. The scheme part of the task URI is used to locate an application that can launch a specific task, form example mforms://mms001. All these interfaces and classes can be found in the Smart Office SDK API and some of them in the API Documentation under Help in the Mashup Designer. When writing JScripts you should be familiar with the Smart Office core programming concepts.

There are new overloads of LaunchTask that can open a window in different ways. If the code does not work on your version of Smart Office it is possible that the method used does not exist in your version.

Opening a new window

Below is an example from Norpe on how to create a non modal and a modal window with JScript. Enjoy.

If you don’t want to have modality to the new window you can create a window that shows up in the task bar using an overload of the LaunchTask method. The script below shows examples of how to launch a modal window and a non-modal window.

         var grid = new Grid();

         return grid;
      public function OnClickClose(sender: Object, e: RoutedEventArgs) {         
         if(host != null) {

    Hi! I have have added a couple of columns to the Window. var gvc = new GridViewColumn();
    How do I get the ISO look & feel? In XAML i looks to be this command:
    But how can i Write this in a JScript – or is there another way to inherate the ISO style?

    I have used this script as a base for a concept. I place a button in the header of MMS240 – a line chosen from the list of equipment and when the button is pressed a new (modal) window is opened which shows some data which will come from a web service (text lines).

    Everything seems to work fine, except when a line is chosen from further down in the list the window doesn’t appear. I suspect it’s being shown but just isn’t visible.

    It only seems to work on the equipment lines from the top of the list.

    Also when the screen does appear, if I press the button on the same selected line, the window moves around (down one line at a time) then eventually moves back to the top.

    Is it possible to control the position of where the new window will open in the desktop?

      Where and witch panel is used? For the Grid you can set colum and row to row and column that does not exist and the use Margin and set top and left.
