C++ CreateProcess() Runs In The Same Window As The First One

I'm using CreateProcess() from a console program to run another console program, but it runs in the same window as the first one.

STARTUPINFO sinfo;
PROCESS_INFORMATION pinfo;

LPSTR commandLine = " \"Cows and Bulls.exe\" test ";

ZeroMemory(&sinfo, sizeof(sinfo));
ZeroMemory(&pinfo, sizeof(pinfo));

if(!CreateProcess(0,commandLine, 0, 0, FALSE, 0, 0, 0, &sinfo, &pinfo))
    cout << "failed";

This is my code. What am I doing wrong? It gets really fun when I add a

for(int i=0; true; i++)
{
    cout << i;
    Sleep(1000);
}

to the first one. Then it starts outputting the numbers IN the next one.

It's like the two programs are merged.. I don't want that, i want to open a new window.

P.S. I'm passing arguments, yes, but if I cut the test the result's the same.

To give the child process a new console you need to set the CREATE_NEW_CONSOLE flag in the dwCreationFlags argument of your call to CreateProcess. Documentation here: http://msdn.microsoft.com/en-gb/library/windows/desktop/ms682425(v=vs.85).aspx
