MFC命令窗口命令

Question

In MFC I want to Create a process by opening Command Window and executing a command in that say open notepad.
i Found this tried it didn't work

STARTUPINFO sInfo = {0};
sInfo.cb = sizeof(sInfo);
PROCESS_INFORMATION pInfo = {0};

CreateProcess("C:\\WINDOWS\\System32\\cmd.exe",""0,0,TRUE,
NORMAL_PRIORITY_CLASS,0,0,&sInfo,&pInfo);

Answer 1

You're not telling cmd to do anything. Try this:

CreateProcess(0, "C:\\WINDOWS\\System32\\cmd.exe /c notepad.exe", 0, 0, TRUE, 0, 0, 0, &sInfo, &pInfo);

But maybe this is easier

ShellExecute(0, "open", "cmd.exe", "/C notepad.exe", 0, SW_HIDE);

Or even this:

system("notepad.exe");

Go to the MSDN document we can see, you don't specify the second parameter that is the command line to excute.

On the other hand, there are no NORMAL_PRIORITY_CLASS enum item for the sixth parameter. You should do like this:

STARTUPINFO si = { sizeof(si) };   
PROCESS_INFORMATION pi;   

si.dwFlags = STARTF_USESHOWWINDOW;   
si.wShowWindow = TRUE;  
TCHAR cmdline[] =TEXT(" notepad.exe");   
BOOL bRet = ::CreateProcess (   
    TEXT("C:\\WINDOWS\\System32\\cmd.exe"),  
    cmdline,    
    NULL,   
    NULL,   
    FALSE,   
    CREATE_NEW_CONSOLE,   
    NULL,   
    NULL,   
    &si,   
    &pi);
