VC++让程序在开机启动时就自动运行，利用win.in文件实现相关程序的自动启动。在该文件的“【Windows】”数据段中，有两个数据项“load=”和“run=”，它们的作用就是在系统启动之后自动地装入和运行相关的程序。如果我们需要在系统起动之后装入并运行一个程序，只将需要运行文件的全文件名添加在该数据项的后面，系统启动后就会自动运行该程序，这里是通过WritePrivateProfileString函数来实现。-VC++ to allow the program to run automatically when you boot, use win.in file automatically start the associated program. In the "[Windows]" section of the document data, there are two data items "load =" and "run =", their role is to start automatically after the system load and run the associated program. If we need to start after the system load and run a program, only the files needed to run the full file name of the data item is added back in, the system will automatically start running the program, here is achieved by WritePrivateProfileString function.
