Comment:

 The limits are a bit all over the place. For the record:

  - The maximum command line length for the CreateProcess function is 32767
 characters. This limitation comes from the UNICODE_STRING structure.
    CreateProcess is the core function for creating processes, so if you
 are talking directly to Win32, then that's the only limit you have to
 worry about. But if you are reaching CreateProcess by some other means,
 then the path you travel through may have other limits.

  - If you are using the CMD.EXE command processor, then you are also
 subject to the 8192 character command line length limit imposed by
 CMD.EXE.

  - If you are using the ShellExecute/Ex function, then you become subject
 to the INTERNET_MAX_URL_LENGTH (around 2048) command line length limit
 imposed by the ShellExecute/Ex functions. (If you are running on Windows
 95, then the limit is only MAX_PATH.)
