Subject: [python-win32] C# ref argument in pywin32 COM server
Message-ID: <CAGqiV-7-UAQy9Mir7id7eMm2GPFnVDBsegAK2dDAKDLf7XxMUw@mail.gmail.com>

Hi there!

I am using win32com.server to make a COM server with Python that is used by
a C# app. I want to implement a C# function in a Python COM server that
looks like this:

public void GetArgs(ref string[] connArgs){
    connArgs= new string[3] { "a", "b", "c" };}

I have tried different approaches with Python but none seem to work. Tried
looking for the documentation but cannot find how to handle arguments that
are passed as reference to Python in the server side. Returning a list or
tuple of utf-8 encoded strings causes the error "All dimensions must be a
sequence of the same size".

Any suggestions on how to approach this?

Thanks in advance for the help.

Kind regards,

Francisco

Not sure if this is the appropriate place for this question, but I was wondering how one prints (hard copies, with an actual printer) PDF documents using python. For example, if I want to write a script to automatically print hard copies of pdfs saved on my computer. I have tried to search online for an answer and believe it should be possible through win32api / win32print but I haven't been able to find an approach that works.
If this isn't the appropriate forum for this question any advice as to where I should look is appreciated!
I am running python 3.7.4, 32 bit
Thanks!

Subject: [python-win32] determine the default printer from RDP
Message-ID: <ff178e3c-f346-f1f2-17d7-4e6c2f973f36@jfcomputer.com>

Hi,

I need a way to determine the default printer (on the users computer) 
from a RDP session.

The user logs on to a RDP session and win32print.GetDefaultPrinter() 
returns a blank.? That makes sense on the RDP session because there 
aren't any default printers.? RDP printing is directed to the default 
printer on the users desktop.

Is there a way to get the default printer from the RDP session.

Thanks for the response - and yes I do have the printers checkbox - 
checked.? It returns a blank.

Hi John,

In the Windows RDP client, under "Show Options" -> "Local Resources" ->
section "Local devices and resources" is "Printers" checked?

I haven't tried what you're referring to, but perhaps that setting is
relevant to your problem?

I was able to discover that a powershell command does in fact find the 
correct default printer.


powershell.exe -command "& {(Get-WmiObject -class win32_printer | where 
{$_.default -eq $true}).name}"
or
 ?Get-WmiObject -query "SELECT * FROM WIN32_PRINTER WHERE Default = TRUE"


is there something in python-win32 I can do to get the same results.

I have discovered a solution to the issue.
import wmi
c = wmi.WMI()
 ?wql = "SELECT * FROM WIN32_PRINTER WHERE Default = TRUE"

 ?for printer in c.query(wql):
 ??????? selectedPrinter = printer.caption

where selectPrinter is the device name of the printer.

Hope this helps somebody in the future.
