A lot of people prefer to build a web app. They think using ASP.Net MVC or PHP + jQuery will be the best option. jQuery can make a web interface as good as a windows UI. Nowadays, web page can do a lot of interactions. Moreover, the users only need a web browser to access the application, no installation of software are required. However, our Company, AdvGen, still has some projects in WPF or Winforms, such as AdvGen Contact Manager and Adv Timer Assistant. That is because jQuery UI is very hard to test and so easy to have bugs. Moreover, WPF and Winform are still able to provide more interactions and easy to build. Thus, we still love WPF and Winforms!

Recently, I traveled to Seoul from Hong Kong. I rented a mobile modem from Vison Data. That costed HKD$60 per day and HKD$1000 as the deposit. This is quite reasonable. Moreover, the process is convenient. I booked the modem online, and then you can pay the rent fee and deposit into their bank account or pay the money in their office. Finally, I picked the modem from their office the day before our trip. Of course you can pay $20 for express post. Then the modem will be delivered to your home.

For speed, that is our reasonable too. 0.97 Mbps for download and 0.43 Mbps for upload.

Lastly, I wish to talk the return process. That is simple, you need to pick back the modem to their office before the second day of your return. Of course you can pay $20 for express post too. Then they will give your a cash cheque to you.

I tried to add a button which will jump a Navigation Control Screen after it clicked. But I ran the application, after the button is clicked, I got this error, 'Push segues can only be used when the source controller is managed by an instance of UINavigationController.'' By try and error, I found that is because the button cannot use "Push" action, you need to use modal action. Then that will work!

During recent Years,"Social Media" is a popular term in the marketing world. A number of people have asked me what is "Social Media Marketing". Social Media is a good tool for marketing. It helps to spread out your name from your friends to their friends, then from their friends' to their friends' friends etc.
You need other good tools. You still need a website. There is a limited information in social media. You need a website to put the detailed information. Moreover, a number of people are still using search engine. You still need a website for search engines to do indexing. Lastly, you need a website to build your corporate image! Please do not forget the old good tool!

Last week, I did my supermarket shopping in Woolworth. I found there is a section for Google Play - Gift Card. That is a good sign for our Android Developer. Therefore, the users do not need a credit card anymore to buy the apps in Google Play. That is more easier to buy apps!
