Generic Class for handling user actions

In this blog I would like to talk about a custom generic class created by me which can be used to handle user actions.In day to day operations in a production environment there are several actions which are performed by the user on a daily basis.This class can be used to consolidate those actions into an application which can be used by the user as a easy navigation tool.Each of these actions can be further divided based on the application area. This class can be typically used in “cockpit” type applications which involve integration of several applications.All the actions required to be performed by the user in each of these applications can be passed on to this class based on the application involved.A docking container containing all the application areas along with the actions is then displayed to the user.The user can click on any action and execute it as per his requirements.

Thanks for sharing Ravi! I would like to check out this class, can you provide the source code via SAPlink?

  Thanks for your comments Ryan.
  I have not used the SAPlink till now.Can you explain to me how I can use it to upload the code ?

    Just put in SAPlink and use Weblogs in the search on the left to read all about it and what others are doing with it.
    A good start point is the blog by Dan McWeeney (one of the creators) called: SAPlink One Week, One New Version — UPDATE
    I was going to write that as a comment to your new blog that I just released 🙂
