用CreateProcess()在MFC中执行批处理命令

//封装CreateProcess

BOOL CFXNAdhocDemoDlg::ProcessCmd(LPTSTR cmd)
{
    ASSERT(cmd!=NULL);

    STARTUPINFO si;
    PROCESS_INFORMATION pi;

    ZeroMemory( &si, sizeof(si) );
    si.cb = sizeof(si);
    ZeroMemory( &pi, sizeof(pi) );

    // Start the child process.
    if( !::CreateProcess( NULL,   // No module name (use command line)
        cmd,        // Command line
        NULL,           // Process handle not inheritable
        NULL,           // Thread handle not inheritable
        FALSE,          // Set handle inheritance to FALSE
        CREATE_NO_WINDOW,//The process is a console application that is being run without a console window
        NULL,           // Use parent's environment block
        NULL,           // Use parent's starting directory
        &si,            // Pointer to STARTUPINFO structure
        &pi )           // Pointer to PROCESS_INFORMATION structure
        )
    {
        //异常处理
        ::MessageBox(NULL,TEXT("执行外部命令出错！"),NULL,MB_OK);
        return FALSE;
    }
    // Wait until child process exits.
    WaitForSingleObject( pi.hProcess, INFINITE );

    // Close process and thread handles.
    CloseHandle( pi.hProcess );
    CloseHandle( pi.hThread );
    return TRUE;
}

//调用封装的函数来执行批处理命令

ProcessCmd(L"help");
