1. Printing
The last time I used my printer with Win32lib was before (1) I installed
Eu 2.3 and (2) I got a new printer with a USB port.
Now when attempting to use getPrinter() routine from Win32lib I get a
message with heading "Printer Err", a warning icon and message "An error
occured during this operation" which doesn't appear to come from
Win32lib so I assume it is from API PrintDlg. I get the error on both
machines, one Win98 and the other XP. My version of comdlg32.dll is
dated 1999 on Win98 and 8/18/2001 on the XP. I get the error whether I
use the USB or Serial Cable with appropriate vendor software added. I
get this error from Win32lib's Generic.exw so it is not related to my
.exw program. I even traded back to the store the printer and got a
different brand and still get the error.
Anyone have an idea?

Do you get the error with any other software? Or just Euphoria?

Here's something that really confuses a newbie like me!
-- Win32.hlp says:
If you use the structure to initialize the dialog box controls, you must
allocate space for and create the DEVMODE
structure. (You should allocate a movable block of memory.)
If you do not use the structure to initialize the dialog box controls, hDevMode
may be NULL. In this case, PrintDlg
allocates memory for the structure, initializes its members, and returns a
handle that identifies it.
-- I'm assuming that win32lib *is* trying to use the structure to initialize the
dialog box,
-- but DEVMODE isn't anywhere in sight ?
i.e:
store( mem, PRINTDLG_lStructSize, SIZEOF_PRINTDLG )
store( mem, PRINTDLG_nMinPage, 1 )
store( mem, PRINTDLG_flags, flags )
store( mem, PRINTDLG_nMaxPage, pMaxPages )
-- Perhaps the 3.10 version has an internal 'workaround' exception handler to
'baby' this, but the 4.0 version does not
?
That " hDevMode *may* be NULL " is really explicit
