  • Python GUI does not update until entire process is finished

    - by ccwhite1
    I have a process that gets a files from a directory and puts them in a list. It then iterates that list in a loop. The last line of the loop being where it should update my gui display, then it begins the loop again with the next item in the list. My problem is that it does not actually update the gui until the entire process is complete, which depending on the size of the list could be 30 seconds to over a minute. This gives the feeling of the program being 'hung' What I wanted it to do was to process one line in the list, update the gui and then continue. Where did I go wrong? The line to update the list is # Populate listview with drive contents. The print statements are just for debug. def populateList(self): print "populateList" sSource = self.txSource.Value sDest = self.txDest.Value # re-intialize listview and validated list self.listView1.DeleteAllItems() self.validatedMove = None self.validatedMove = [] #Create list of files listOfFiles = getList(sSource) #prompt if no files detected if listOfFiles == []: self.lvActions.Append([datetime.datetime.now(),"Parse Source for .MP3 files","No .MP3 files in source directory"]) #Populate list after both Source and Dest are chosen if len(sDest) > 1 and len(sDest) > 1: print "-iterate listOfFiles" for file in listOfFiles: sFilename = os.path.basename(file) sTitle = getTitle(file) sArtist = getArtist(file) sAlbum = getAblum(file) # Make path = sDest + Artist + Album sDestDir = os.path.join (sDest, sArtist) sDestDir = os.path.join (sDestDir, sAlbum) #If file exists change destination to *.copyX.mp3 sDestDir = self.defineDestFilename(os.path.join(sDestDir,sFilename)) # Populate listview with drive contents self.listView1.Append([sFilename,sTitle,sArtist,sAlbum,sDestDir]) #populate list to later use in move command self.validatedMove.append([file,sDestDir]) print "-item added to SourceDest list" else: print "-list not iterated"

  • JAVA-how to manually compose a MIME multipart message

    - by Augusto Picciani
    I need to compose manually a MIME multipart message. I don't need to use any library to doing it. I'm trying this without success: out.println("From:myemail@mydomain"); out.flush(); out.println("To:myemail@mydomain"); out.flush(); out.println("Date:Thu, 25 Nov 2011 01:00:50 +0100"); out.flush(); out.println("Subject:manual test 269"); out.flush(); out.println("MIME-version:1.0"); out.flush(); out.print("Content-Type: multipart/mixed; boundary=\"1234567\"\n\n"); out.println("--1234567"); out.flush(); out.println("Content-Type: text/plain; charset:utf-8"); out.flush(); out.print("Content-Transfer-Encoding: 7bit\n\n"); out.flush(); out.print("test message\n\n"); out.flush(); out.println("--1234567"); out.flush(); out.println("Content-Type: text/html; charset:utf-8"); out.flush(); out.print("Content-Transfer-Encoding: 7bit\n\n"); out.flush(); out.print("<p><strong>test message in html</strong></p>\n\n"); out.flush(); out.println("--1234567--"); out.flush(); out.print("\r\n.\r\n"); out.flush(); Problem is that my mail client see the headers (from,subject,date,ecc.) but it doesn't see the message body. If i try without multipart it works fine. Maybe problem is in whitespaces character.

  • Indent or comment several text lines with VI

    - by Werner
    Hi, can vim or vim be used to comment or indent at the same time a number of lines? For instance: for item in Lista: ind = int(floor(1.0*(item-lmin)/width)) if ind==nintervals: ind=ind-1 print item,ind comment it to: #for item in Lista: #ind = int(floor(1.0*(item-lmin)/width)) #if ind==nintervals: #ind=ind-1 #print item,ind or indent it to: for item in Lista: ind = int(floor(1.0*(item-lmin)/width)) if ind==nintervals: ind=ind-1 print item,ind Thanks P.D. Is relevant the difference between VI and VIM?

  • Condition checking vs. Exception handling

    - by Aidas Bendoraitis
    When is exception handling more preferable than condition checking? There are many situations where I can choose using one or the other. For example, this is a summing function which uses a custom exception: # module mylibrary class WrongSummand(Exception): pass def sum_(a, b): """ returns the sum of two summands of the same type """ if type(a) != type(b): raise WrongSummand("given arguments are not of the same type") return a + b # module application using mylibrary from mylibrary import sum_, WrongSummand try: print sum_("A", 5) except WrongSummand: print "wrong arguments" And this is the same function, which avoids using exceptions # module mylibrary def sum_(a, b): """ returns the sum of two summands if they are both of the same type """ if type(a) == type(b): return a + b # module application using mylibrary from mylibrary import sum_ c = sum_("A", 5) if c is not None: print c else: print "wrong arguments" I think that using conditions is always more readable and manageable. Or am I wrong? What are the proper cases for defining APIs which raise exceptions and why?

  • PHP Strange error "0:". Possible Object syntax problem?

    - by Michael Stone
    I'm trying to transfer a site from one hosting company to another. I was using 000webhost until the client had hosting and a domain. Now that the client has their domain and hosting, using FatCow.com, I can not for the life of me, debug my PHP code. I'm not getting any errors. I have a successful DB connection. If you procedurally display data, it works, but when I try to use my original objects, something is breaking and just returns "0:". I have all errors on. On old server where the site worked: PHP Version 5.2.11 MySQL Version: 5.0.81 On new server where I get the "0:": PHP Version 5.2.12 MySQL Version 5.0.32 I've setup a test page to test just the output of the variables with the DB connection. Below is my code: <?php error_reporting(E_ALL); ini_set('display_errors', '1'); try { $link = mysql_connect('connectionstring', 'username', 'password'); if (!$link) { die('Could not connect: ' . mysql_error()); } else{ $db = mysql_select_db('a8210422_lit'); } if($db){ include_once('admin/classes/clsPOW.php'); include_once('admin/classes/clsProviders.php'); $pow = new POW(); $prov = new Providers(); $new = $pow->getNew(); $newAr = $new->val(); $get = $prov->getAll($newAr['providerId']); $getAr = $get->val(); $img = $getAr['image']; $name = $getAr['provider']; $desc = $getAr['description']; $zip = $getAr['zip']; $web = $getAr['link']; if($zip==0){ $zip = "Unavailable"; } print $img; print $name; print $desc; print $zip; print $web; } else{ print 'fail!'; } } //catch exception catch(Exception $e) { echo 'Message: ' .$e->getMessage(); } ?>

  • Python's asyncore to periodically send data using a variable timeout. Is there a better way?

    - by Nick Sonneveld
    I wanted to write a server that a client could connect to and receive periodic updates without having to poll. The problem I have experienced with asyncore is that if you do not return true when dispatcher.writable() is called, you have to wait until after the asyncore.loop has timed out (default is 30s). The two ways I have tried to work around this is 1) reduce timeout to a low value or 2) query connections for when they will next update and generate an adequate timeout value. However if you refer to 'Select Law' in 'man 2 select_tut', it states, "You should always try to use select() without a timeout." Is there a better way to do this? Twisted maybe? I wanted to try and avoid extra threads. I'll include the variable timeout example here: #!/usr/bin/python import time import socket import asyncore # in seconds UPDATE_PERIOD = 4.0 class Channel(asyncore.dispatcher): def __init__(self, sock, sck_map): asyncore.dispatcher.__init__(self, sock=sock, map=sck_map) self.last_update = 0.0 # should update immediately self.send_buf = '' self.recv_buf = '' def writable(self): return len(self.send_buf) > 0 def handle_write(self): nbytes = self.send(self.send_buf) self.send_buf = self.send_buf[nbytes:] def handle_read(self): print 'read' print 'recv:', self.recv(4096) def handle_close(self): print 'close' self.close() # added for variable timeout def update(self): if time.time() >= self.next_update(): self.send_buf += 'hello %f\n'%(time.time()) self.last_update = time.time() def next_update(self): return self.last_update + UPDATE_PERIOD class Server(asyncore.dispatcher): def __init__(self, port, sck_map): asyncore.dispatcher.__init__(self, map=sck_map) self.port = port self.sck_map = sck_map self.create_socket(socket.AF_INET, socket.SOCK_STREAM) self.bind( ("", port)) self.listen(16) print "listening on port", self.port def handle_accept(self): (conn, addr) = self.accept() Channel(sock=conn, sck_map=self.sck_map) # added for variable timeout def update(self): pass def next_update(self): return None sck_map = {} server = Server(9090, sck_map) while True: next_update = time.time() + 30.0 for c in sck_map.values(): c.update() # <-- fill write buffers n = c.next_update() #print 'n:',n if n is not None: next_update = min(next_update, n) _timeout = max(0.1, next_update - time.time()) asyncore.loop(timeout=_timeout, count=1, map=sck_map)

  • Calculating the pixel size of a string with Python

    - by Aristide
    I have a Python script which needs to calculate the exact size of arbitrary strings displayed in arbitrary fonts in order to generate simple diagrams. I can easily do it with Tkinter. The problem is the results seem to depend on the version of Python and/or the system. import Tkinter as tk import tkFont root = tk.Tk() times12 = tkFont.Font(family="times",size=12) print times12.metrics("linespace"), print times12.measure("Hello world") times24 = tkFont.Font(family="times",size=24) print times24.metrics("linespace"), print times24.measure("Hello world") Python 2.5 on Mac OS X gives the actual pixel measurements: 12 57 24 116 Python 2.6.1 on Mac OS X gives: 14 58 27 115 Python 2.6.3 on Windows XP gives: 19 71 36 154 Such a need being quite common, I suspect I did something wrong. Any idea?

  • Display numbers from 1 to 100 without loops or conditions

    - by Harsha
    Is there a way to print numbers from 1 to 100 without using any loops or conditions like "if"? We can easily do using recursion but that again has an if condition. Is there a way to do without using "if" as well? Also no repetitive print statements,or a single print statement containing all the numbers from 1 to 100. A solution in Java is preferable.

  • How to replace the nth column/field in a comma-separated string using sed/awk?

    - by Peter Meier
    assume I have a string "1,2,3,4" Now I want to replace, e.g. the 3rd field of the string by some different value. "1,2,NEW,4" I managed to do this with the following command: echo "1,2,3,4" | awk -F, -v OFS=, '{$3="NEW"; print }' Now the index for the column to be replaced should be passed as a variable. So in this case index=3 How can I pass this to awk? Because this won't work: echo "1,2,3,4" | awk -F, -v OFS=, '{$index="NEW"; print }' echo "1,2,3,4" | awk -F, -v OFS=, '{$($index)="NEW"; print }' echo "1,2,3,4" | awk -F, -v OFS=, '{\$$index="NEW"; print }' Thanks for your help!

    I need files ending with ".pdf" or ".png"; here's my attempt: find /Users/robottinosino/Desktop/_PublishMe_ -type f -regex '.*[pdf|png]' this incorrectly includes files ending with "Apdf", "Zpdf", etc. (missing literal dot before file extension) I tried adjusting the pattern to: find /Users/robottinosino/Desktop/_PublishMe_ -type f -regex '.*\.[pdf|png]' but then no results are returned. Escaping the . with a backslash does not work. Why?

However, that prints them like this (let's say x is 5): x= 5 How can I make them print on the same line?
