Hmm... no, it does not mention this at all.
>From MSDN doc on MaxLength:
Windows NT 4.0, Windows 2000, Windows Server 2003 family Platform Note: For single line text box controls, if the MaxLength
property is set to 0, the maximum number of characters the user can enter is 2147483646 or an amount based on available memory,
whichever is smaller. For multiline text box controls, the maximum number of characters the user can enter is 4294967295 or an
amount based on available memory, whichever is smaller.
Windows 95, Windows 98, Windows 98 Second Edition, Windows Millennium Edition Platform Note: For single line text box controls, if
the MaxLength property is set to 0, the maximum number of characters the user can enter is 32,766 or an amount based on available
memory, whichever is smaller. For multiline text box controls, the maximum number of characters the user can enter is 65,535 or an
amount based on available memory, whichever is smaller.
According to this, since I'm running Windows XP (although not mentioned, I assume it follows with Windows 2000/2003) with a
multiline text box I should get up to 4 billion characters (or memory, but I have 512MB of RAM, I'm not running out at 32K...).
