>Anyone have the code for the WINAPI equivalent -- one that won't open a command window while changing the 'Hidden' attribute for a file?

Here's the declaration:

DECLARE SHORT SetFileAttributes IN Win32API;
  STRING @lpFileName, INTEGER dwFileAttributes

Now in order to set the hidden attribute of an existing file, you'd do something like this (with an additional declaration):

DECLARE INTEGER GetFileAttributes IN Win32API;
  STRING @lpFileName
#DEFINE FILE_ATTRIBUTE_HIDDEN 2
lnattribs = GetFileAttributes(@lcfile)
lnattribs = BITOR(lnattribs, FILE_ATTRIBUTE_HIDDEN)
llresult = (SetFileAttributes(@lcfile, lnattribs) # 0)

BTW, there's a class that will do this in the Files under Win 32 and other APIs.

hth,
