主管催了，看了8个星期没明白，谢谢，几十行代码，到底启动几个进程，在哪

Question

我测试好象是启动2个，但是实在是找不到2个啊

Answer 1

CreateProcess()就是创建进程的，所以应该是两个，分别在startcmd（）、startProgram（）中

Answer 2

startcmd 是 startProgram的一个if分支选择，createporcess失败之后才会startcmd的。。

Answer 3

1、判断有没有用户名密码，没有退出，有则继续
2、判断服务器有没有配置好，没有退出，有则继续
3、通过 CreateProcess 启动程序，不成功的话就用获取程序路径然后再 CreateProcess 启动程序
