VC创建子进程静默执行解压、转移等命令行

本代码经过VS2019测试，调试了很久的命令，欢迎参考。

include <iostream>

    //测试解压PDX，然后将解压出来的jar文件和dll文件移动到jarFILE目录，然后删除解压目录

    std::string strPdxDIRFullName = ".\\1\\2\\3\\4\\5\\PDX\\" + strFolderName + "\\";
    std::string strJarDIRFullName = strPdxDIRFullName + "*.jar ";

// 等待子进程的退出 
WaitForSingleObject(pi.hProcess, INFINITE);
// 关闭子进程句柄

return iResult;
