Subject: [python-win32] printing landscape in Windows
Message-ID: <B5B6938384884CA5BBF678FAF952182D@DE64>

Just about a month ago I started reading Learning Python by Mark Lutz.
It's a new paradigm for me. I have a whole bunch of old mainframe files
with carriage control characters as the 1st character in each line.
Well, a got a very simple script working except I need to be able to
print landscape on my pc printer. Does anyone by chance have sample code I
could cut and paste to print landscape? I'm running Windows 7 Pro and
Python 2.7


#prt1a is a copy of prt11

import os, sys, tempfile
import win32api, win32print

printer_name = win32print.GetDefaultPrinter ()
hPrinter = win32print.OpenPrinter (printer_name)

hJob = win32print.StartDocPrinter (hPrinter, 1, ('alfie', None, "RAW"))
win32print.StartPagePrinter (hPrinter)

for line in open('alf1'):
    cc = line[0]
    line = line[1:]
    line = line.rstrip()
    
    if   cc == '1': line = '\f' + line
    elif cc == ' ': line = '\n' + line
    elif cc == '0': line = '\n\n' + line
    elif cc == '-': line = '\n\n\n' + line

    line = line + '\r'   # takes care of the overprinting
    win32print.WritePrinter(hPrinter, line)

win32print.WritePrinter(hPrinter,"\f")
win32print.EndPagePrinter (hPrinter)
win32print.EndDocPrinter (hPrinter)
win32print.ClosePrinter (hPrinter)


my test data 'alf1':

1                 QWDDNNNDNDN
++2                 /111111111
++2a                XXXXXXXX11
3                ZDDDDNDNDNNN
++4               #/1111111111
++4a              #XXXXXXXXX11
++4 b             #WWWWWWWWWW1
5   MMMMMMNMMMMMMMMNMNNNNMNNNM
++6  IIIIII1IIIIIIII1I1111I111I
++6a IIIIII1IIIIIIII1I1111I111I
7   NNMNNNNNNNNNNNNNNNNNNNNNMM
++8  11I111111111111111111111II

I don't have a cut and paste example on hand, but you might benefit from
reading the source of this module, or even using it:

    MSWinPrint 1.1 : Python Package Index
    https://pypi.python.org/pypi/MSWinPrint

The method they show for setting landscape mode (setting
devmode.Orientation) looks like it will blend in with what you have with
only a little adjustment.

It seems I'm wrong about just needing a little adjustment. When you use
WritePrinter, you are sending raw bytes to the printer, thanks to opening
the device in "RAW" mode. In this mode, you would need to send the actual
printer escape code that sets it to Landscape, in the language of its
default driver which may be PCL or XPS, or may be something proprietary.

In contrast, MSWinPrint creates a printer device context (dc) and draws to
it with GDI commands, which is a more flexible device-independent method.

Apologies for the false lead, I should have tested it first.

Subject: [python-win32] Issue with refresh of ODBC linked table and
 submitting credentials in excel using Python
Message-ID: <CAJaCrHhEu-jXo4abJ1Cnr6cE57rGmyViw1tNZYo8d+k8FxBjXg@mail.gmail.com>

I have the following code:

import win32com.clientimport os


file1= r'C:\\Users\file.xlxm'
def refresher():
    if os.path.exists(file1):
        xl = win32com.client.DispatchEx("Excel.Application")
        xl.Workbooks.Open(Filename=file1,ReadOnly=1)
        xl.Visible = 1



        xl.Workbooks(1).Close(SaveChanges=1)
        xl.Application.Quit()
        del xl
refresher()

Which gets me into the file, but I am unsure of how to refresh a ODBC
connected table that requires a simple form submission of user credentials.
The current settings dont allow me to save credentials so a script seems to
be the only solution. Any suggestions?

This will allow me to quickly update my models without have to do it
manually in excel.

Thanks!

I think you are saying that you have an Excel spreadsheet which imports
data from an ODBC data source, as talked about in Overview of connecting to
(importing) data
<https://support.office.com/en-ca/article/Overview-of-connecting-to-importing-data-c0ad7aec-ff1a-4e48-9c21-dc18a102433f>
.

If that is correct, then my suggestion would be to eliminate Excel from the
picture, and manipulate the database directly using Python and SQL.
Unfortunately, the version of adodbapi which ships with the present latest
version of pywin32 is broken, so you will have to download directly from
http://sf.net/projects/adodbapi until the next release. Using ADO you can
write SQL commands to manipulate data in any ODBC data source, or in an
ACCESS database, or in an Excel spreadsheet.
