system调用命令行命令而不显示命令行窗口

system调用命令行命令而不显示命令行窗口

通常用system调用命令行命令时都会弹出黑底白字的命令行窗口,下面的代码可以不显示弹出的命令行窗口。

代码如下

 #pragma comment( linker, "/subsystem:/"windows/" /entry:/"mainCRTStartup/"" ) // 设置入口地址
 #include   <windows.h>
 #include   <stdio.h>   

 #define   COMMENDLINE   "ping 127.0.0.1"

 //调用命令行命令而不显示命令行窗口
 BOOL system_hide(char* CommandLine)
 {
     SECURITY_ATTRIBUTES   sa;
     HANDLE   hRead,hWrite;   

     sa.nLength   =   sizeof(SECURITY_ATTRIBUTES);
     sa.lpSecurityDescriptor   =   NULL;
     sa.bInheritHandle   =   TRUE;
     if   (!CreatePipe(&hRead,&hWrite,&sa,))
     {
         return   FALSE;
     }     

     STARTUPINFO   si;
     PROCESS_INFORMATION   pi;
     si.cb   =   sizeof(STARTUPINFO);
     GetStartupInfo(&si);
     si.hStdError   =   hWrite;
     si.hStdOutput   =   hWrite;
     si.wShowWindow   =   SW_HIDE;
     si.dwFlags   =   STARTF_USESHOWWINDOW   |   STARTF_USESTDHANDLES;
     //关键步骤，CreateProcess函数参数意义请查阅MSDN
     if   (!CreateProcess(NULL, CommandLine, NULL,NULL,TRUE,NULL,NULL,NULL,&si,&pi))
     {
         return   FALSE;
     }
     CloseHandle(hWrite);   

     char   buffer[]   =   {};
     DWORD   bytesRead;
     while(true)
     {
         memset(buffer,,strlen(buffer));
         if(ReadFile(hRead,buffer,,&bytesRead,NULL)==NULL)
             break;
         //buffer中就是执行的结果，可以保存到文本，也可以直接输出
         //printf(buffer);//这行注释掉就可以了
         Sleep();
     }
     return   TRUE;
 }   

 int main(int argc, char* argv[])
 {
     system_hide(COMMENDLINE);//不显示命令窗口
     //system(COMMENDLINE);//显示命令行窗口
     return ;
 }
