Can't CreateProcess application?

[Dang.D.Khanh]

Hi,
I use the following code to launch excel:

   STARTUPINFO Start;
    PROCESS_INFORMATION ProcInfo;
    ZeroMemory(&Start, sizeof(STARTUPINFO));
    Start.cb = sizeof(Start);
    Start.dwFlags = STARTF_USESHOWWINDOW;

    
    LPWSTR pszExcelPath =
	 L"C:\\Program Files\\Microsoft Office\\Office14\\EXCEL.EXE";

    ::CreateProcess(NULL, pszExcelPath, 0, 0, 1,
	  NORMAL_PRIORITY_CLASS, 0, NULL, &Start, &ProcInfo);

but i always get this error,

Exception thrown at 0x00007FF8AB5B7500 (KernelBase.dll) in sap.exe: 0xC0000005: Access violation writing location 0x00007FF81E0E04D4.

How do I fix it?
Thanks you!

Hi,
I'm not sure but changing the code to worked for me.
::CreateProcess(pszExcelPath,NULL, 0, 0, 1,
NORMAL_PRIORITY_CLASS, 0, NULL, &Start, &ProcInfo);
I've got a new question here.
Please help!

It is very clear described in CreateProcess documentation:

lpCommandLine

The command line to be executed.

The maximum length of this string is 32,767 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.
