  • Why am I getting this warning about my app delegate and CLLocationManageDelegate?

    - by Dan Ray
    Observe this perfectly simple UIViewController subclass method: -(IBAction)launchSearch { OffersSearchController *search = [[OffersSearchController alloc] initWithNibName:@"OffersSearchView" bundle:nil]; EverWondrAppDelegate *del = [UIApplication sharedApplication].delegate; [del.navigationController pushViewController:search animated:YES]; [search release]; } On the line where I get *del, I am getting a compiler warning that reads, Type 'id <UIApplicationDelegate>' does not conform to the 'CLLocationManagerDelegate' protocol. In fact, my app delegate DOES conform to that protocol, AND what I'm doing here has nothing at all to do with that. So what's up with that message? Secondary question: sometimes I can get to my navigationController via self.navigationController, and sometimes I can't, and have to go to my app delegate's property to get it like I'm doing here. Any hint about why that is would be very useful.

  • django + xmppy: send a message to two recipients

    - by Agrajag
    I'm trying to use xmpppy for sending jabber-messages from a django-website. This works entirely fine. However, the message only gets sent to the -first- of the recipients in the list. This happens when I run the following function from django, and also if I run it from an interactive python-shell. The weird part though, is that if I extract the -body- of the function and run that interactively, then all the recipients (there's just 2 at the moment) get the message. Also, I do know that the inner for-loop gets run the correct count times (2), because the print-statement does run twice, and return two different message-ids. The function looks like this: def hello_jabber(request, text): jid=xmpp.protocol.JID(settings.JABBER_ID) cl=xmpp.Client(jid.getDomain(),debug=[]) con=cl.connect() auth=cl.auth(jid.getNode(),settings.JABBER_PW,resource=jid.getResource()) for friend in settings.JABBER_FRIENDS: id=cl.send(xmpp.protocol.Message(friend,friend + ' is awesome:' + text)) print 'sent message with id ' + str(id) cl.disconnect() return render_to_response('jabber/sent.htm', locals())

  • does a switch idiom make sense in this case?

    - by the ungoverned
    I'm writing a parser/handler for a network protocol; the protocol is predefined and I am writing an adapter, in python. In the process of decoding the incoming messages, I've been considering using the idiom I've seen suggested elsewhere for "switch" in python: use a hash table whose keys are the field you want to match on (a string in this case) and whose values are callable expressions: self.switchTab = { 'N': self.handleN, 'M': self.handleM, ... } Where self.handleN, etc., are methods on the current class. The actual switch looks like this: self.switchTab[selector]() According to some profiling I've done with cProfile (and Python 2.5.2) this is actually a little bit faster than a chain of if..elif... statements. My question is, do folks think this is a reasonable choice? I can't imagine that re-framing this in terms of objects and polymorphism would be as fast, and I think the code looks reasonably clear to a reader.

  • Perl ftp question, like the previous ones ...

    - by Jerry Scott
    I need to move or copy a simple text file from one web site to another web site. I have administrator rights to both web sites. The first web site has a large data file (again, just a text file), certain records are selected and written to a team file (for entry into a tournament). Next I go through paypal and pay for the entries. The second site is for the the club running the tournament and I use IPN to return to a script on their site and if it verified, I add the team memebers into the master file for the tournament. I am limited to the ONE IPN script on the tournament site because I have a ton of other entries that come in from all over. The first site has the rosters for the state and no need to type all that data from each club, use the rosters like I use for all the non-paypal tounamenmts. I can ftp the team file to the second server and place it in the folder just like it was created from scratch from that server originally and everything should go fine but I took the examples and tried them and nothing. Here's the code section: my $custom = $in->param('custom'); my $filename = "$ENV{DOCUMENT_ROOT}/database/$custom"; my $usjochost = '208.109.14.105'; my $okserieshost = '208.109.181.196'; my $usjocuser = 'teamentry'; my $okseriesuser = 'okwaentry'; my $usjocpw = 'Password1'; my $okseriespw = 'Password1'; my $file = $custom; my $usjocpath ='/home/content/u/s/j/usjoc/html/database/'; my $okseriespath ='/home/content/o/k/s/okseries/html/database/'; $ftp = Net::FTP->new($okserieshost, Debug => 0) or die "Could not connect to '$okserieshost': $@"; $ftp->login($okseriesuser, $okseriespw) or die sprintf "Could not login: %s", $ftp->message; #$ftp->cwd(/database) or die sprintf "Could not login: %s", $ftp->message; $ftp->get($filename); #$ftp = Net::FTP->new($usjochost, Debug => 0) or die "Could not connect to '$usjochost': $@"; $ftp->quit; I NEED to READ the file on the first web site (okseries.com) and write the file on the second web site (usjoc.com). I have no problem reading and writing the file on the server, is sending the file to the second server. HELP! I'm not a genius at PERL.

  • TabRenderer with no visual styles enabled?

    - by DxCK
    I want to draw a custom TabControl with custom functionality. To do this, i inherited the Panel class and overrided OnPaint method to draw with TabRenderer class. The problem is that TabRenderer working only when visual styles enabled (can be checked with TabRenderer.IsSupported), but what should i do if visual styles disabled? In this case, I thought using the ControlPaint class to draw tabs without visual styles, but it has no draw method related to Tabs. I want it basically to behave visually like the regular TabControl.

  • Catching error caused by InitialContext.lookup

    - by Martin Schröder
    I'm developing a command line client (Java SE6) that now needs to talk to a Glassfish 2.1 server. The code for setting up this connection is try { final InitialContext context = new InitialContext(); final String ejbName = GeneratorCancelledRemote.class.getName(); generatorCancelled = (GeneratorCancelledRemote) context.lookup(ejbName); } catch (Throwable t) { System.err.println("--> Could not call server:"); t.printStackTrace(System.err); runWithOutEJB = true; } I'm now testing it without a running server and the client (when run from Eclipse 4.2) just bombs with 31.10.2012 10:40:09 com.sun.corba.ee.impl.transport.SocketOrChannelConnectionImpl WARNUNG: "IOP00410201: (COMM_FAILURE) Connection failure: socketType: IIOP_CLEAR_TEXT; hostname: localhost; port: 3700" org.omg.CORBA.COMM_FAILURE: vmcid: SUN minor code: 201 completed: No at com.sun.corba.ee.impl.logging.ORBUtilSystemException.connectFailure(ORBUtilSystemException.java:2783) at com.sun.corba.ee.impl.logging.ORBUtilSystemException.connectFailure(ORBUtilSystemException.java:2804) at com.sun.corba.ee.impl.transport.SocketOrChannelConnectionImpl.(SocketOrChannelConnectionImpl.java:261) at com.sun.corba.ee.impl.transport.SocketOrChannelConnectionImpl.(SocketOrChannelConnectionImpl.java:274) at com.sun.corba.ee.impl.transport.SocketOrChannelContactInfoImpl.createConnection(SocketOrChannelContactInfoImpl.java:130) at com.sun.corba.ee.impl.protocol.CorbaClientRequestDispatcherImpl.beginRequest(CorbaClientRequestDispatcherImpl.java:192) at com.sun.corba.ee.impl.protocol.CorbaClientDelegateImpl.request(CorbaClientDelegateImpl.java:184) at com.sun.corba.ee.impl.protocol.CorbaClientDelegateImpl.is_a(CorbaClientDelegateImpl.java:328) at org.omg.CORBA.portable.ObjectImpl._is_a(ObjectImpl.java:112) at org.omg.CosNaming.NamingContextHelper.narrow(NamingContextHelper.java:69) at com.sun.enterprise.naming.SerialContext.narrowProvider(SerialContext.java:134) at com.sun.enterprise.naming.SerialContext.getCachedProvider(SerialContext.java:259) at com.sun.enterprise.naming.SerialContext.getRemoteProvider(SerialContext.java:204) at com.sun.enterprise.naming.SerialContext.getProvider(SerialContext.java:159) at com.sun.enterprise.naming.SerialContext.lookup(SerialContext.java:409) at javax.naming.InitialContext.lookup(InitialContext.java:392) at com.werkii.latex.generator.Generator.main(Generator.java:344) Caused by: java.lang.RuntimeException: java.net.ConnectException: Connection refused: connect at com.sun.enterprise.iiop.IIOPSSLSocketFactory.createSocket(IIOPSSLSocketFactory.java:347) at com.sun.corba.ee.impl.transport.SocketOrChannelConnectionImpl.(SocketOrChannelConnectionImpl.java:244) ... 14 more Caused by: java.net.ConnectException: Connection refused: connect at sun.nio.ch.Net.connect(Native Method) at sun.nio.ch.SocketChannelImpl.connect(SocketChannelImpl.java:532) at com.sun.corba.ee.impl.orbutil.ORBUtility.openSocketChannel(ORBUtility.java:105) at com.sun.enterprise.iiop.IIOPSSLSocketFactory.createSocket(IIOPSSLSocketFactory.java:332) ... 15 more It's o.k. for now (while I'm still in development) that it bombs, but it does this repeatedly and the catch clause is never reached (even though I'm catching Throwable) - the message is not printed.

  • Sending message from one server to another in Twisted

    - by Casey Patton
    I've implemented my servers in the following way: def makeServer(application, port): factory = protocol.ServerFactory() factory.protocol = MyChat factory.clients = [] internet.TCPServer(port, factory).setServiceParent(application) application = service.Application("chatserver") server1 = makeServer(application, port=1025) server2 = makeServer(application, port=1026) server3 = makeServer(application, port=1027) Note that MyChat is an event handling class that has a "receiveMessage" action: def lineReceived(self, line): print "received", repr(line) for c in self.factory.clients: c.transport.write(message + '\n') I want server1 to be able to pass messages to server2. Rather, I want server1 to be treated as a client of server2. If server1 receives the message "hi" then I want it to send that same exact message to server2. How can I accomplish this?

  • Windows7 Installer takes priority how to move it back during installation using C#?

    I've a custom Action on Deployment project of .NET Applicaiton, which contains custom dialogbox to enter certain parameters, on invalid parameters I've shown MessageBox.Show - but its being hide by installer window, I tried windows forms too with Activate, TopMost, Focus,bring2front, etc serveral options but it comes by default behind the windows installer window and due to this user is not able to identify why installing process is not finishing - because actually its waiting for user to read the MessageBox and press OK. I've tried to implement IWin32Window with the handler of MsiExec Process, and shown the Messagebox but still its not working, anyone has idea ??? Here is my installer.cs function defination, public override void Install(IDictionary stateSaver)

  • How to use another type of EditingControl in a single C# 3.5 DataGridView column ?

    - by too
    Is this possible to have two (or more) different kinds of cells to be displayed interchangeably in single column of C# .Net 3.5 DataGridView? I know one column has specified single EditingControl type, yet I think grid is flexible enough to do some tricks, I may think of only: Adding as many invisible columns to grid as required types of cells and on CellBeginEdit somehow exchange current cell with other column's cell Create custom column and custom cell with possibility of changing EditingControl for single cell Which approach is better, are there any examples ?

  • Wireshark Plugin: Dissecting Payloads With Multiple Packets Per UDP Frame

    - by John Dibling
    I am writing a Wireshark plugin to dissect a protocol that places multiple application-level packets in a single UDP frame. There is no enclosing protocol that indicates how many packets there are in the frame. So essentially, the payload coming down the wire will look like this: uint64 sequence1 uint64 data1 uint8 flags1 uint64 sequence2 uint64 data2 uint8 flags2 : : : uint64 sequence_n uint64 data_n uint8 flags_n In my server code that actually processes this information, I simply loop through the frame until I reach the end. In looking through the plugins included with the wireshark source code, I didn't see any protocols that did any looping like this. I know other protocols pack multiple payloads per frame. What is the cannonical or standard way to handle protocols like this in a Wireshark dissector?

  • getResourceAsStream returns HttpInputStream not of the entire file

    - by khue
    Hi, I am having a web application with an applet which will copy a file packed witht the applet to the client machine. When I deploy it to webserver and use: InputStream in = getClass().getResourceAsStream("filename") ; The in.available() always return a size of 8192 bytes for every file I tried, which means the file is corrupted when it is copied to the client computer. The InputStream is of type HttpInputStream (sun.net.protocol.http.HttpUrlConnection$httpInputStream). But while I test applet in applet viewer, the files are copied fine, with the InputStream returned is of type BufferedInputStream, which has the file's byte sizes. I guess that when getResourceStream in file system the BufferedInputStream will be used and when at http protocol, HttpInputStream will be used. How will I copy the file completely, is there a size limited for HttpInputStream? Thanks a lot.
