FUNCTION: GenerateUnknownShortcutName
PARAMETERS:
pwzSourceFilename - TCHAR Source Path and Filename that cannot be created.
This value will be changed to a valid path\filename
pwzDestFilename - After pwzSourceFilename is converted to a valid filename,
the valid path will be returned here in a UNICODE string.
dwSize - Size of the pwzDestFilename buffer in chars.
DESCRIPTION:
This function will replace the filename at the end of
the path in pwzFilename with "Untitled.url". If that file
exists, it will try, "Untitled1.url" and so on until it can
be unique.
WARNING:
This function will only allow the incoming value be in ANSI
because these helper functions (like PathRemoveFileSpecW) won't
work on Win95 when compiled in UNICODE. (CharNextW isn't supported
on Win95)
