ITBLogs.InfoHOWTO: Find a Physical Path in ASP.Net from URL
In a number of situations, we need to know a Physical Path in a server from URL. For example, we need to upload some photo. Thus, this is a very common task, and is very easy to do in C#
Code
string serverPath = Server.Map("~/Photo"); // e.g. it returns "C:\site\Photo" |
Not just about coding
We are in Information Technology Industry for a few years. We do a lot of coding every day. Most of people believe we only need to know about the programming syntax.
Well, we still need to know about the theories behind that, such as basic computer architectures and software design theories. We need to know all basic stuff, then we can write some good software!
WPF and Winforms are alive
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!
Stay online in Korea
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.
iOS Error:'Push segues can only be used when the source controller is managed by an instance of UINavigationController.''
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!
