we have the three buttons Login, Register and Cancel. Here each button has different functionality. In this way each submit button will post a form to the server but will provide different values of each button.

This article explains how to handle multiple submit buttons in a single view in MVC. Sometimes we need multiple submit buttons in the same form, but by default, MVC supports a single post method. Let's say I have a scenario where we need to add more than one button to get a different type of export functionality, such as Export To Excel, Export To CSV, Export To PDF. In the same way, if users click on the other two buttons it will follow the same process. If the user clicks on export to CSV, then it will execute ExportCSV() method and when the user clicks on Export To PDF, then it will execute the ExportPDF() method.

TRACE宏对于VC下程序调试来说是很有用的东西，有着类似printf的功能；该宏仅仅在程序的DEBUG版本中出现，当RELEASE的时候该宏就完全消失了，从而帮助你调试也在RELEASE的时候减少代码量

屏坏也有很多种情况啊。如果只是触屏坏，准备根OTG线和蓝牙鼠标。用有线鼠标打开调试模式，连接上蓝牙鼠标（用蓝牙鼠标是因为连上电脑后，adb调试要给电脑授权，要在手机上点确认）。之后就按提示操作。如果是内屏坏了，什么都看不到的话，就比较麻烦了
