Question

I am trying to start a server using CreateProcess(). Here is the Code:

int APIENTRY WinMain(HINSTANCE hInstance,
                     HINSTANCE hPrevInstance,
                     LPSTR     lpCmdLine,
                     int       nCmdShow)
{
    // TODO: Place code here.

    int result; 
    STARTUPINFO si;
    PROCESS_INFORMATION pi;
    CreateProcess("C:\\AP\\DatabaseBase\\dbntsrv.exe", "*** WHAT SHOULD I PUT HERE***", NULL, NULL, FALSE, 0, NULL, NULL, &si, &pi);
    return 0;
}

I did not understand from the documentation what the 2nd parameter should be. Can you please help me with it?
Thank You

From MSDN:

lpCommandLine [in, out, optional]

The command line to be executed. The maximum length of this string is 32,768 characters, including the Unicode terminating null
character. If lpApplicationName is NULL, the module name portion of
lpCommandLine is limited to MAX_PATH characters.

The Unicode version of this function, CreateProcessW, can modify the contents of this string. Therefore, this parameter cannot be a
pointer to read-only memory (such as a const variable or a literal
string). If this parameter is a constant string, the function may
cause an access violation.

The lpCommandLine parameter can be NULL. In that case, the function uses the string pointed to by lpApplicationName as the
command line.

So NULL is OK there, at least. As soon as you don’t pass arguments.
