Let's wrap up what we have learn in the first set of tutorials by building a polling application! This is given to you as an exercise.

But in case of need, you can download the full application package for reference. The package includes the client library, all the source files and image file used to build the application. Besides, SQL scripts for creating the database table is given to you also.

Note that before downloading starts, you need to complete a survey provided by CPALead.

Sorry that I won't accept email asking for a copy of it. If you have difficulties in completing the surveys or do not want to do that, you can consider subscribing to our mailing list service. For USD29.99 per year, any eBook and free demo application source code packages published here will be sent to you. Payment can be made via PayPa (my paypal account is takwing@graduate.hku.hk).
