Re: Application monitor
Many thanks for your answers. Respect Init, I need a cross platform solution. Most of times my system will run in Win98 and XP (more on XP than 98) Respect Twisted... Mmm... I already started with another networking library (TCPServer and SimpleXMLRPCServer), and I wouldn't like to mix things because I don't know so much about those libraries. I know that Twisted can do what I already have. But replacing it can be a hard task. So I would like to have a function like FindPID(exename) --> PID, or something more generic that could tell me the PID of a running program, and kill him in a certain moment.

Re: Addressing the last element of a list
Hi
Proposition 1:
> data = [0, None, 2, 0]
> ref = data[-1]
> ref = 1
> assert data[-1] == 1
Logically, it doesn't work. Here you are assigning to ref a NEW value.
That won't replace the data[-1] value. It's out of logic this
proposition.
While this (proposition 2):
data = [0, None, 2, ["hello"]]
ref = data[-1]
ref.append("world")
does work, because you are assigning to ref THAT list ["hello"]. So, if
you have THAT list, and appends a value, THAT list will be modified.
ref is pointing to THAT object. So, I don't understand why you write
the first proposition, like if that can be a normal thinking of how to
do the second proposition :-S
Well, I hope that newcomers to Python don't confuse himselves :)

Yes, it works. But in my case, I need to run the program totally
separated from my main program. So, when I start a new program through
subprocess, it doesn't unlink. I mean, if I close my main app, so does
the launched program. With startfile() it does the job, but I then I
have to find what pid is through win32all module, etc.
it would be very good if I can use spawnl

A way for launch an app monitor
Hello,
I'm in the way for creating an application and its monitor. Yes, there
are 2 applications: The main app, and a monitor. The last one monitors
the main application for keeping it alive, and viceversa. But if I
close the main app, I want to close the monitor.
That is very easy under nt systems, but in 98 is a little more tricky
because of the problem with closing processes.
For example, I can't use the following code on a win98 machine:
def FindPID(exename):
"""
usage:
pid=FindPID("pythonw.exe")
print pid
"""
a = os.popen4('tasklist /FI "IMAGENAME eq '+exename+'"')
a[0].flush()
try:
info=a[1].readlines()[3].split()
except:
info=[exename,"NotFound"]
return info[1] #PID
because the "tasklist" command doesn't exist on win98. Also, I tried to
install the kill.exe and a dont-remember-dll (from the Win98 Resource
Kit), but it doesn't work.
So my solution (need help on this) is that I have been thinking on
letting the monitor listen for socket connection. Through this, the
main app can tell him to close when the main app closes correctly. Do
you think this is well thought? Any suggestions?

> if cond:

Let me tell you something: I'm not a one-liner coder, but sometimes It
is necesary.
For example:
I need to translate data from a DataField to Another.
def Evaluate(condition,truepart,falsepart):
if condition:
return truepart
else:
return falsepart
dOldDataFields = {}
dNewDataFields = {}
dNewDataFields = {
'CODE': dOldDataFields['CODEDATA'],
'DATE': dOldDataFields['DATE'],
'CONTACT': Evaluate(dOldDataFields['CONTACTTYPE']==2,
dOldDataFields['FIRSTCONTACT'], dOldDataFields['SECONDCONTACT'])
}
With this, I created a new dic very easy, saving in
dNewDataFields['CONTACT'] the value of dOldDataFields['FIRSTCONTACT']
or the value of dOldDataFields['SECONDCONTACT'] depending on
dOldDataFields['CONTACTTYPE']. How you do this in a practic way without
the use of one-line code? It is needed! You can't avoid it! Even using
a = [if_false_expr, if_true_expr][predicate] or a function, you'll
always have to use a one-line code (for this purpose, of course).

An app without GUI
Hello to all, I have to build a server app without GUI. This app must be an xml-rpc server, so it has to be up all the time.

Print a PDF transparently
Hi to all, I want to print a PDF right from my python app transparently. With "transparently" I mean that no matter what program handles the print petition, the user shouldn't be noticed about it. For example, when I want to print a PDF, Adobe Acrobat fires and keep opened. This is what I don't want to happen (and I thing there are a lot of people who want this too). So I just want to send the PDF to the right handler and print it. That's all. I've seen some things like Adobe's Postscript driver that can read a PDF, or Ghostscript, but I still don't know how to use it. Any help for printing a PDF transparently? Thank you Daniel -- http://mail.python.org/mailman/listinfo/python-list
Re: Print a PDF transparently
Hi, Thanks for all the answers. My main purpose is to print on Windows systems (98,2000,XP) and permit to print pages of 1/3 of a letter height, and make the printer to stop at that point (in dot matrix printers). When I have a PDF with that paper size and send it to print from Acrobat, it prints and stops perfect (in Win98, I have to create a custom form consisting of that paper size). The problem is that PDF files have to be handled by external applications, or non-free drivers. Based on all this, I have been investigating about postscript files. I realize that printers do handle this language, so I think if I have a .ps file and send it directly to the printer, it should do the job, right? (this is certainly a question) If the answer is True, no matter in what platform I am, if I send the same .ps to the printer, it should print the same result. And if all of these is true, then, my problem reduces to generate the .ps file. Comments please Daniel -- http://mail.python.org/mailman/listinfo/python-list

I'd be happy if I just do "printer.Print(file.pdf/.ps)" and walá, the printing just starts (in 98,2000,XP... sounds like a dream), without having another window opened. If it opens, but then closes, it's perfect too. I have tried installing Ghostscript, and having a .ps when I order that file to print, it does the job. The thing here is that I have to install it. All this has to be easilly installed (with InnoSetup, for example), because I have to install it on 70 offices. So I can't leave it to another installation process. All of these offices have a dot matrix printers Epson LX-300, which has PostScript level 3 built-in. Where can I find how to send a .ps directly to the printer?

Re: Print a PDF transparently
> Have you seen this? > http://tgolden.sc.sabren.com/python/win32_how_do_i/print.html > In particular, the section on using win32print directly. Yes, I have. The problems is that an external program is launched for handling the file and print it. In the case of PDF, acrobat is launched. In the case of PS, Ghostview is launched. When printing a PDF, acrobat keeps alive, so the user has to close it manually. On the other hand, Ghostview is opened, prints the file and closes automatically. The last one is which I find the best for me, until now, (because the Ghostview closes automatically). If I decide to go this way, my problem then is to transform a pdf to ps, or generate a ps directly. For further information on what I want, please, refer to my first two posts in this topic.

Re: Print a PDF transparently
Thank you very much Roger Upole and Tim Golden for your posts... I found an exe that can print a pdf file (using Acrobat Reader) on any windows printer right from the command line. It opens Acrobat, order it to print the pdf file at a certain printer and then closes Acrobat. The exe is a c-compiled program from someone that supplied it in a forum. That works almost perfect for me. The only thing now is that when I'm printing a PDF in dot matrix printers, the output is very ugly, and I don't know how to improve it. I think I will go for printing in plain text. The only problem with it is that one have to depend on the physical printer configuration. Daniel -- http://mail.python.org/mailman/listinfo/python-list
PDF on dot matrix printers
Hi to all, Does anyone know about how to make a dot matrix printer print a PDF file with the quality of a Microsoft Word printing? When I print from Microsoft Word, the output is perfect for the kind of printer. But, from a PDF file, the characters are distortionated in an uniform way. With "uniform" I mean that no matter where I put the characters in the page, the character "e" always will be smaller than an "a". So, when seeing the output page, and trying to read what it has written, you realize that the characters have different heights... It could be a matter of resolution, obviously not in the printer, but in the PDF. So I'm wondering if there are some tasks that I could do for accomplish it.
