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,0))     
    {   
        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[4096]   =   {0};   
    DWORD   bytesRead;     
    while(true)     
    {   
        memset(buffer,0,strlen(buffer));
        if(ReadFile(hRead,buffer,4095,&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(100);     
    }     
    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 0;   
}
