I'm developing a debugging automation system using https://github.com/MarioVilas/winappdbg.
I would like to retrieve process name from event object. Here is my code:
def EventHandler(event):
print 'Inside event handler'
# I want to print the process name here, In this case which should be somefile.exe
debug = Debug( EventHandler, bKillOnExit = True )
proc = debug.execv(['c:\somefile.exe','arg'])
debug.loop()
The tool author answered my question on github : Here is the solution
We can do event.get_process().get_filename(), or if we want to be more fancy:
process = event.get_process()
name = process.get_filename()
print "Process: %s" % name

I needed to write a solution to write data on and then print RFID labels en-masse, each generated as .png images from a template python script and data taken from a database or excel file.
To print the program simply calls the relative system utility (CUPS on unix systems) using subprocess.check_call(print_cmd) passing the image file (saved on a ram-mounted file system for minimal disk usage)
Now, it also needs to run on Windows systems, but there is not really a decent system utility for that, and solutions under a similar question command line tool for print picture? don't account for print-job completion or if the job results in an error, the margins are all screwed and the image is always rotated 90 degrees for some reason.
How can I sanely print an image using a command or a script in Windows and wait for it to complete successfully or return an error if the job results in an error?
Possibly with no dependencies
If you can install dependencies, there are many programs that offer a solution out-of-the-box.
The only sane way i could find to solve this issue with no dependencies is by creating a powershell script to account for this
[CmdletBinding()]
param (
[string] $file = $(throw "parameter is mandatory"),
[string] $printer = "EXACT PRINTER NAME HERE"
)
$ERR = "UserIntervention|Error|Jammed"
$status = (Get-Printer -Name $printer).PrinterStatus.ToString()
if ($status -match $ERR){ exit 1 }
# https://stackoverflow.com/a/20402656/17350905
# only sends the print job to the printer
rundll32 C:\Windows\System32\shimgvw.dll,ImageView_PrintTo $file $printer
# wait until printer is in printing status
do {
$status = (Get-Printer -Name $printer).PrinterStatus.ToString()
if ($status -match $ERR){ exit 1 }
Start-Sleep -Milliseconds 100
} until ( $status -eq "Printing" )
# wait until printing is done
do {
$status = (Get-Printer -Name $printer).PrinterStatus.ToString()
if ($status -match $ERR){ exit 1 }
Start-Sleep -Milliseconds 100
} until ( $status -eq "Normal" )
I would then need to slightly modify the print subprocess call to
powershell -File "path\to\print.ps1" "C:\absolute\path\to\file.png"
Then there are a couple of necessary setup steps:
(discaimer, I don't use windows in english so i don't know how the english thigs are supposed to be called. i will use cursive for those)
create an example image, right click and then select Print
from the print dialog that opens then set up all the default options you want, like orientation, margins, paper type, etc etc for the specific printer you're gonna use.
Go to printer settings, under tools then edit Printer Status Monitoring
edit monitoring frequency to "only during print jobs". it should be disabled by default
in the next tab, modify polling frequency to the minimum available, 100ms during print jobs (you can use a lower one for the while not printing option
Assuming the following:
only your program is running this script
theres always only 1 printing job at a time for a given printer
the printer drivers were not written by a monkey and they actually report the current, correct printer status
This little hack will allow to print an image from a command and await job completion, with error management; and uses only windows preinstalled software
Further optimization could be done by keeping powershell subprocess active and only passing it scripts in the & "path\to\print.ps1" "C:\absolute\path\to\file.png" format, waiting for standard output to report an OK or a KO; but only if mass printing is required.
Having had to work on this again, just wanted to add a simpler solution in "pure" python using the pywin32 package
import time
import subprocess
from typing import List
try:
import win32print as wprint
PRINTERS: List[str] = [p[2] for p in wprint.EnumPrinters(wprint.PRINTER_ENUM_LOCAL)]
PRINTER_DEFAULT = wprint.GetDefaultPrinter()
WIN32_SUPPORTED = True
except:
print("[!!] an error occured while retrieving printers")
# you could throw an exception or whatever
# bla bla do other stuff
if "WIN32_SUPPORTED" in globals():
__printImg_win32(file, printer_name)
def __printImg_win32(file: str, printer: str = ""):
if not printer:
printer = PRINTER_DEFAULT
# verify prerequisites here
# i still do prefer to print calling rundll32 directly,
# because of the default printer settings shenaningans
# and also because i've reliably used it to spool millions of jobs
subprocess.check_call(
[
"C:\\Windows\\System32\\rundll32",
"C:\\Windows\\System32\\shimgvw.dll,ImageView_PrintTo",
file,
printer,
]
)
__monitorJob_win32(printer)
pass
def __monitorJob_win32(printer: str, timeout=16.0):
p = wprint.OpenPrinter(printer)
# wait for job to be sheduled
t0 = time.time()
while (time.time()-t0) < timeout:
ptrr = wprint.GetPrinter(p, 2)
# unsure about those flags, but definitively not errors.
# it seems they are "moving paper forward"
if ptrr["Status"] != 0 and ptrr["Status"] not in [1024,1048576]:
raise Error("Printer is in error (status %d)!" % ptrr["Status"])
if ptrr["cJobs"] > 0:
break
time.sleep(0.1)
else:
raise Error("Printer timeout sheduling job!")
# await job completion
t0 = time.time()
while (time.time()-t0) < timeout:
ptrr = wprint.GetPrinter(p, 2)
if ptrr["Status"] != 0 and ptrr["Status"] not in [1024,1048576]:
raise Error("Printer is in error (status %d)!" % ptrr["Status"])
if ptrr["cJobs"] == 0 and ptrr["Status"] == 0:

wprint.ClosePrinter(p)

I've been making this pp size machine, which is somewhat like dank memer's one
#client.command()
async def pp(ctx,member : discord.Member):
size=random.randint(1,10)
message = "8"
for x in range (size):
message= message + "="
if x == size-1:
message = message + "D"
if member == "PROTATO#6826":
message = "8D"
ppsize = discord.Embed(color=discord.Colour.orange(), title=f"PP size",description=f"""{member}'s penis
{message} """)
await ctx.send(embed = ppsize)
But i want to rig the command for a certain user to only show "8D" instead of the random lengths.
But no matter what it is the
if member == "PROTATO#6826":
message = "8D"
code doesnt run or gets over looked?
Can someone help me out with this?
You can check if the member mentioned has the same id as a specific user. You can either enable developer mode on discord, or you can print the member.id at the very beginning. Do view a code example below.
#client.command()
async def pp(ctx, member: discord.Member):
print(member.id) # this would print a user's unique id
message = "Hey!"
if member.id == 394506589350002688: # replace this id with what was printed at the start
message = "Hello!"
await ctx.send(message)

I have to run bash heavy-job.sh <data-num> (that takes 0.5~2 days) frequently on my computer to process data located at ~/a/data/num . The script call a few sub-processes sequentially and write a log to ~/a/result/num.log . I have done this manually until now.
I wanted to visualize processed tasks and it's status(success or fail), etc as html table. I wrote simple sinatra app to render a table that shows
the list of ~/a/data/num to be processed
~/a/result/num.log exists or not (process not-launched/processing/done)
it's status (the log file contains the word "error" or not)
I found that it would be convenient that if I could launch a bash heavy-job.sh <data-num> from the sinatra app, log the tasks (and info like time,date,etc..) and it's args (heavy-jobs takes some optional args ) and show them as html table.
So I need something that manages jobs and logs to files (or db).
First I wrote a code like below for test (! for test, not integrated with my system yet !), but later I found resque is what i wanted. I am a beginner and not sure if my decision is reasonable or not.
my questions are
is it reasonable to use resque to manage external long-running commands (and log tasks)
or should I use another tool (not necessarily ruby-tool).
(extra;) the task-manager and the sinatra app should work separately (and communicate each other over REST or something) OR not ?
The jobs are not critical since I can retry tasks manually later if failed.
I am not good at English and my question may be misleading. I appreciate any help :) .

def initialize()
#pids = []

delete_idx = nil
ret = nil
#pids.each_with_index do |p, idx|
pid,status = Process.waitpid2(p, Process::WNOHANG)
unless pid.nil?
delete_idx = idx
ret = [pid,status]
break
end
end
if delete_idx
#pids.delete_at(delete_idx)
return ret
else
# no task fininshed
return nil
end
end
def waitall()
ret = waitall
raise "interal error" if ret.size != pids.size
return ret
end

I am using Qt Ruby
How do I keep the value of a user entered QlineEdit to keep its state even after the program is closed, in that way, the user can access the contents the next time he opens the program.
Solution 1 - using File.write/read:
edit_widget = Qt::LineEdit.new(parent)
File.write(filename, edit_widget.text)
exit
After the program re-start:
text = File.read(filename)
edit_widget.setText text
Solution 2 - using QSettings:
settings = Qt::Settings.new(filename, Qt::Settings::NativeFormat)
edit_widget = Qt::LineEdit.new(parent)
edit_widget.text = "abcde"
settings.setValue("field1", Qt::Variant.fromValue(edit_widget.text))
settings.sync
exit
After the program re-start:
settings = Qt::Settings.new(filename, Qt::Settings::NativeFormat)
edit_widget = Qt::LineEdit.new(parent)
edit_widget.text = settings.value("field1").toString
Hey all,
I am building a gui in wich there is an edit box, waiting for the user to write a name.
Currently I force the user to give a legitimate name with this code :
NewPNUName = get(handles.nameOfNewPNU, 'String');
if ( isempty(NewPNUName) ||...
strcmp(NewPNUName,'Enter the name for the new PNU') )
errordlg('Please enter a name for the new PNU.');
elseif (~ischar(NewPNUName(1)))
errordlg('The PNU name should start with a letter.');
else
handles.NewPNUName = NewPNUName;
end
if (~isempty(handles.NewPNUName))
% Do all the things needed if there is a legit name
end
What it does is nothing if the user didn't write a legit name.
What I want it to do is to make a popup with an edit box, asking the user to input the wanted name again, until it is a legitimate name.
Thanks for the help!
EDIT:
following #woodchips advice I corrected my code to the foloowing:
NewPNUName = get(handles.nameOfNewPNU, 'String');
ValidName = ~isempty(NewPNUName) && isletter(NewPNUName(1)) &&...
~strcmp(NewPNUName,'Enter the name for the new PNU');
while (~ValidName)
if ( isempty(NewPNUName) ||...
strcmp(NewPNUName,'Enter the name for the new PNU') )
NewPNUName = char(inputdlg('Please enter a name for the new PNU.','No name entered'));
elseif (~isletter(NewPNUName(1)))
NewPNUName = char(inputdlg('The name of the new PNU should start with a letter. Please enter a new name',...
'Invalid name entered'));
else
allConds = 'are met'
end
ValidName = ~isempty(NewPNUName) && isletter(NewPNUName(1)) &&...
~strcmp(NewPNUName,'Enter the name for the new PNU');
end
So, put a while loop around a block of code, that generates an inputdlg box. Set the condition on the while loop to be that the result is a valid one.
