首先问高们一个问题，不知道能不能实现？
比如我有一个变量
LPSTR lpCmd = "DOS命令";
LPCTSTR lpCmdFile = "C:\\WINDOWS\\system32\\cmd.exe";
ShellExecute(NULL, "open", lpCmdFile, NULL, NULL, SW_SHOW);
然后用Spy++查找窗口名称得到窗口句柄
WND CmdHwnd = ::FindWindow(NULL, "C:\WINDOWS\system32\cmd.exe");
::PostMessage(CmdHwnd, WM_SETTEXT, 0, (LPARAM)completeCommand);
::PostMessage(CmdHwnd, WM_KEYDOWN, 13, 0);
我这么做不行，请高手指导，谢谢！
我MySQL数据库密码重置主要代码在这。
声明
public:
//对比两次密码输入是否相同
BOOL CheckPassword();
//得到MySQL数据库安装路径
BOOL GetMysqlPath(LPSTR lpMysql);
//提升进程操作权限
BOOL ElevatedPermissions();
//强制结束应用程序进程
BOOL KillProcess(LPCSTR lpProcessName);
//跳过MySQL数据库安全验证
BOOL SkipMysqlVerification(LPSTR lpMysqld, char completePath[]);
//进入MySQL数据库root用户
BOOL EnterMysqlRoot(char MysqldPath[], char completeMysql[]);
//修改MySQL数据库root用户密码
BOOL ModifyRootPassword(LPSTR lpModifyRootPwd);
//执行控制台命令
BOOL ExecDosCommand(LPTSTR lpCommandLine);
//启动系统服务
BOOL StartSystemService(LPCTSTR lpServiceName);

就是进行MySQL数据库后执行控制台命令怎么都不成功，请麻烦高手协助，100块钱不多，但我尽力了，谢谢！
