ASP.NET Custom Server Controls: Extended Wordhack Control with Key Combination - Summary
(Page 5 of 5 )
To work with my demonstration, you need to download my sample zip file, available from a link on the first page of this article. The zip contains a solution with two web forms. The first works with the “WordHack” control and the second with the “CharacterHack” control. You can test the functionality of those controls by executing the solution (with WebForm1.aspx as the start page) and just typing any of the following words blindly (with or without focus on the textbox also):
And it would automatically redirect to the specific web site you typed. Execute the solution again (with WebForm2.aspx as start page) and just press “Ctrl+g” (for google) or “Ctrl+y” (for yahoo).
Coming to the pros and cons of this control, you should keep in mind the following issues, before you start enhancing (or using) the control.
- You need to test with all the popular browsers you consider important (as I meant this control only for Internet Explorer 6.0 +) and modify accordingly.
- The “CharacterHack” control currently works with only alphabets. If you need to work with digits (say “Ctrl+9” etc), you need to work with the ASCII values of that criteria.
- We will not be able to hack (using the “CharacterHack” control) certain control characters which are managed by the browser environment (for instance, “Ctrl+N” cannot be hacked as it would open new window).
- You can also support the functionality of the “Shift” and “Alt” keys with the “CharacterHack” control using “event.shiftKey” or “event.altKey” within your JavaScript.
- You can even write better JavaScript to eliminate the property “OrderOfPreference” by maintaining your own internal indexing. But you would need to understand the flow of rendering and JavaScript injection wherever possible. If you are new to rendering, you can follow my article “Breaking the Secrets of Rendering” within the same series.
That finishes our matter. Please understand that all of the ASP.NET controls (in this series) have been tested only with Internet Explorer 6.0. I request that you make the necessary modifications to suit your needs of cross browser compatibility. I leave it to the developers to further enhance this control. The areas of improvement would include better eventing, better JavaScript, cross browser support,and so on. Good luck.
