ASP.NET Send Image Attachment With Email Without Saving To Filesystem

- by KGO

I'm trying to create a form that will send an email with an attached image and am running into some problems. The form I am creating is rather large so I have created a small test form for the purpose of this question. The email will send and the attachment will exist on the email, but the image is corrupt or something as it is not viewable. Also.. I do not want to save the image to the filesystem. You may think it is convoluted to take the image file from the fileupload to a stream, but this is due to the fact that the real form I am working on will allow multiple files to be added through a single fileupload and will be saved in session, thus the images will not be coming from the fileupload control directly on submit.

Stored proc running 30% slower through Java versus running directly on database

- by James B

Hi All, I'm using Java 1.6, JTDS 1.2.2 (also just tried 1.2.4 to no avail) and SQL Server 2005 to create a CallableStatement to run a stored procedure (with no parameters). I am seeing the Java wrapper running the same stored procedure 30% slower than using SQL Server Management Studio. I've run the MS SQL profiler and there is little difference in I/O between the two processes, so I don't think it's related to query plan caching. The stored proc takes no arguments and returns no data. It uses a server-side cursor to calculate the values that are needed to populate a table. I can't see how the calling a stored proc from Java should add a 30% overhead, surely it's just a pipe to the database that SQL is sent down and then the database executes it....Could the database be giving the Java app a different query plan?? I've posted to both the MSDN forums, and the sourceforge JTDS forums (topic: "stored proc slower in JTDS than direct in DB") I was wondering if anyone has any suggestions as to why this might be happening? Thanks in advance, -James (N.B. Fear not, I will collate any answers I get in other forums together here once I find the solution) Java code snippet: sLogger.info("Preparing call..."); stmt = mCon.prepareCall("SP_WB200_POPULATE_TABLE_limited_rows"); sLogger.info("Call prepared. Executing procedure..."); stmt.executeQuery(); sLogger.info("Procedure complete."); I have run sql profiler, and found the following: Java app : CPU: 466,514 Reads: 142,478,387 Writes: 284,078 Duration: 983,796 SSMS : CPU: 466,973 Reads: 142,440,401 Writes: 280,244 Duration: 769,851 (Both with DBCC DROPCLEANBUFFERS run prior to profiling, and both produce the correct number of rows) So my conclusion is that they both execute the same reads and writes, it's just that the way they are doing it is different, what do you guys think? It turns out that the query plans are significantly different for the different clients (the Java client is updating an index during an insert that isn't in the faster SQL client, also, the way it is executing joins is different (nested loops Vs. gather streams, nested loops Vs index scans, argh!)). Quite why this is, I don't know yet (I'll re-post when I do get to the bottom of it) Epilogue I couldn't get this to work properly. I tried homogenising the connection properties (arithabort, ansi_nulls etc) between the Java and Mgmt studio clients. It ended up the two different clients had very similar query/execution plans (but still with different actual plan_ids). I posted a summary of what I found to the MSDN SQL Server forums as I found differing performance not just between a JDBC client and management studio, but also between Microsoft's own command line client, SQLCMD, I also checked some more radical things like network traffic too, or wrapping the stored proc inside another stored proc, just for grins. I have a feeling the problem lies somewhere in the way the cursor was being executed, and it was somehow giving rise to the Java process being suspended, but why a different client should give rise to this different locking/waiting behaviour when nothing else is running and the same execution plan is in operation is a little beyond my skills (I'm no DBA!). As a result, I have decided that 4 days is enough of anyone's time to waste on something like this, so I will grudgingly code around it (if I'm honest, the stored procedure needed re-coding to be more incremental instead of re-calculating all data each week anyway), and chalk this one down to experience. I'll leave the question open, big thanks to everyone who put their hat in the ring, it was all useful, and if anyone comes up with anything further, I'd love to hear some more options...and if anyone finds this post as a result of seeing this behaviour in their own environments, then hopefully there's some pointers here that you can try yourself, and hope fully see further than we did. I'm ready for my weekend now! -James

Postfix "warning: cannot get RSA private key from file"

- by phew

I just followed this tutorial to set up a postfix mailserver with dovecot and mysql as backend for virtual users. Now I got the most parts working, I can connect to pop3 pop3s imap and imaps. Using echo TEST-MAIL | mail [email protected] works fine, when I log into my hotmail account it shows the email. It also works in reverse hence my MX entry for mydomain.com finally has been propagated, so I am being able to receive emails sent from [email protected] to [email protected] and view them in Thunderbird using STARTTLS via IMAP. Doing a bit more research after I got the error message "5.7.1 : Relay access denied" when trying to send mails to [email protected] using Thunderbird being logged into [email protected], I figured out that my server was acting as an "Open Mail Relay", which - ofcourse - is a bad thing. Digging more into the optional parts of the tutorial like shown workaround.org/comment/2536 and workaround.org/ispmail/squeeze/postfix-smtp-auth I decided to complete these steps aswell to be able to send mails via [email protected] through Mozilla Thunderbird, not getting the error message "5.7.1 : Relay access denied" anymore (as common mailservers reject open relayed emails). But now I ran into an error trying to get postfix working with SMTPS, in /var/log/mail.log it reads Sep 28 17:29:34 domain postfix/smtpd[20251]: warning: cannot get RSA private key from file /etc/ssl/certs/postfix.pem: disabling TLS support Sep 28 17:29:34 domain postfix/smtpd[20251]: warning: TLS library problem: 20251:error:0906D06C:PEM routines:PEM_read_bio:no start line:pem_lib.c:650:Expecting: ANY PRIVATE KEY: Sep 28 17:29:34 domain postfix/smtpd[20251]: warning: TLS library problem: 20251:error:140B0009:SSL routines:SSL_CTX_use_PrivateKey_file:PEM lib:ssl_rsa.c:669: That error is logged right after I try to send a mail from my newly installed mailserver using SMTP SSL/TLS via port 465 in Thunderbird. Thunderbird then tells me a timeout occured. Google has a few results concerning that problem, yet I couldn't get it working with any of those. I would link some of them here but as a new user I am only allowed to use two hyperlinks. My /etc/postfix/master.cf looks like smtp inet n - - - - smtpd smtps inet n - - - - smtpd -o smtpd_tls_wrappermode=yes -o smtpd_sasl_auth_enable=yes and nmap tells me PORT STATE SERVICE [...] 465/tcp open smtps [...] my /etc/postfix/main.cf looks like smtpd_banner = $myhostname ESMTP $mail_name (Debian/GNU) biff = no append_dot_mydomain = no readme_directory = no #smtpd_tls_cert_file = /etc/ssl/certs/postfix.pem #default postfix generated #smtpd_tls_key_file = /etc/ssl/private/ssl-cert-snakeoil.key #default postfix generated smtpd_tls_cert_file = /etc/ssl/certs/postfix.pem smptd_tls_key_file = /etc/ssl/private/postfix.pem smtpd_use_tls = yes smtpd_tls_session_cache_database = btree:${data_directory}/smtpd_scache smtp_tls_session_cache_database = btree:${data_directory}/smtp_scache smtpd_sasl_type = dovecot smtpd_sasl_path = private/auth smptd_sasl_auth_enable = yes smtpd_recipient_restrictions = permit_mynetworks, permit_sasl_authenticated, reject_unauth_destination myhostname = mydomain.com alias_maps = hash:/etc/aliases alias_database = hash:/etc/aliases myorigin = /etc/mailname mydestination = localhost.com, localhost relayhost = mynetworks = 127.0.0.0/8 [::ffff:127.0.0.0]/104 [::1]/128 mailbox_size_limit = 0 recipient_delimiter = + inet_interfaces = all virtual_mailbox_domains = mysql:/etc/postfix/mysql-virtual-mailbox-domains.cf virtual_mailbox_maps = mysql:/etc/postfix/mysql-virtual-mailbox-maps.cf virtual_alias_maps = mysql:/etc/postfix/mysql-virtual-alias-maps.cf virtual_transport = dovecot dovecot_destination_recipient_limit = 1 mailbox_command = /usr/lib/dovecot/deliver The *.pem files were created like described in the tutorial above, using Postfix To create a certificate to be used by Postfix use: openssl req -new -x509 -days 3650 -nodes -out /etc/ssl/certs/postfix.pem -keyout /etc/ssl/private/postfix.pem Do not forget to set the permissions on the private key so that no unauthorized people can read it: chmod o= /etc/ssl/private/postfix.pem You will have to tell Postfix where to find your certificate and private key because by default it will look for a dummy certificate file called "ssl-cert-snakeoil": postconf -e smtpd_tls_cert_file=/etc/ssl/certs/postfix.pem postconf -e smtpd_tls_key_file=/etc/ssl/private/postfix.pem I think I don't have to include /etc/dovecot/dovecot.conf here, as login via imaps and pop3s works fine according to the logs. Only problem is making postfix properly use the self-generated, self-signed certificates. Any help appreciated! EDIT: I just tried this different tutorial on generating a self-signed certificate for postfix, still getting the same error. I really don't know what else to test. I also did check for the SSL libraries, but all seems to be fine: root@domain:~# ldd /usr/sbin/postfix linux-vdso.so.1 => (0x00007fff91b25000) libpostfix-global.so.1 => /usr/lib/libpostfix-global.so.1 (0x00007f6f8313d000) libpostfix-util.so.1 => /usr/lib/libpostfix-util.so.1 (0x00007f6f82f07000) libssl.so.0.9.8 => /usr/lib/libssl.so.0.9.8 (0x00007f6f82cb1000) libcrypto.so.0.9.8 => /usr/lib/libcrypto.so.0.9.8 (0x00007f6f82910000) libsasl2.so.2 => /usr/lib/libsasl2.so.2 (0x00007f6f826f7000) libdb-4.8.so => /usr/lib/libdb-4.8.so (0x00007f6f8237c000) libnsl.so.1 => /lib/libnsl.so.1 (0x00007f6f82164000) libresolv.so.2 => /lib/libresolv.so.2 (0x00007f6f81f4e000) libc.so.6 => /lib/libc.so.6 (0x00007f6f81beb000) libdl.so.2 => /lib/libdl.so.2 (0x00007f6f819e7000) libz.so.1 => /usr/lib/libz.so.1 (0x00007f6f817d0000) libpthread.so.0 => /lib/libpthread.so.0 (0x00007f6f815b3000) /lib64/ld-linux-x86-64.so.2 (0x00007f6f83581000) After following Ansgar Wiechers instructions its finally working. postconf -n contained the lines as it should. The certificate/key check via openssl did show that both files are valid. So it indeed has been a permissions problem! Didn't know that chown'ing the /etc/ssl/*/postfix.pem files to postfix:postfix is not enough for postfix to read the files.

WPF: Updating visibility of controls not updating the screen

- by Brad McBride

I will preface this by stating that I am new to WPF programming and may be making multiple errors. Any insight that can be provided to help me improve in my skills are greatly appreciated. I am working with a WPF application and am looping through a list of objects that contain properties that describe a document that should be built on the fly and automatically printed. I am attempting to display a small grid in the interface that shows the document being built before it is printed. This serves two purposes: one, it allows the user to see work being done by the application. Two, it renders the items on the screen so that I can then have something to actually print since WPF appears to not be able to load an image for printing dynamicaly without displaying it on the screen. In my code, I am setting the various elements in the grid and setting the visibility to visible. However, the UI is not updating and the printed document doesn't look as intended since the image never shows up on the screen. Here is the XAML that I have set up <Grid x:Name="LayoutRoot" Background="Black"> <Grid Name="previewGrid" Grid.Row="1" Grid.Column="1" Background="White" Visibility="Hidden"> <Canvas Name="pageCanvas" HorizontalAlignment="Center" VerticalAlignment="Center"> <Grid Name="pageGrid" Width="163" Height="211"> <Grid.ColumnDefinitions> <ColumnDefinition Width="81.5"></ColumnDefinition> <ColumnDefinition Width="81.5"></ColumnDefinition> </Grid.ColumnDefinitions> <TextBlock Grid.Column="0" Name="copyright" TextAlignment="Center" HorizontalAlignment="Center" VerticalAlignment="Bottom"></TextBlock> <Image Name="pageImage" Grid.Column="1" HorizontalAlignment="Center" VerticalAlignment="Center"></Image> </Grid> </Canvas> .....canvas for pages 2-4 not shown but structure is the same as for pageGrid..... </Grid> </Grid> </Window> Here is the code behind that is supposed to set the elements. previewGrid.Visibility = Windows.Visibility.Visible pageURI = New Uri(pageCollection(i).iamgeURL, UriKind.Absolute) pageGrid.Visibility = Windows.Visibility.Visible bmp.BeginInit() bmp.StreamSource = getCachedURLStream(cardURI) bmp.EndInit() pageImage.Source = bmp copyright.Text = copyrightText cardPreviewGrid.UpdateLayout() ' More code that prints the visual element pageGrid previewGrid.Visibility = Windows.Visibility.Hidden The code in codebehind loops through a number of times depending on how many different documents the user prints. Basically it builds a visual element for a page, prints an XPS version of it and then builds the next page and prints it, etc. Once all pages have been processed, the job is actually sent to the printer. The only purpose of this application is to let the user print these documents so there is not other task that they can do in the application while the documents print. I thought that putting this task in a background thread would help to update the UI but since I am trying to manipulate items directly on the UI thread it would appear that this option won't work for me. What am I doing wrong here and how can I improve the code so that I can get the behavior that I am trying to achieve?

Mobile App Data Syncronization

- by Matt Rogish

Let's say I have a mobile app that uses HTML5 SQLite DB (and/or the HTML5 key-value store). Assets (media files, PDFs, etc.) are stored locally on the mobile device. Luckily enough, the mobile device is a read-only copy of the "centralized" storage, so the mobile device won't have to propagate changes upstream. However, as the server changes assets (creates new ones, modifies existing, deletes old ones) I need to propagate those changes back to the mobile app. Assume that server changes are grouped into changesets (version number n) that contain some information (added element XYZ, deleted id = 45, etc.) and that the mobile device has limited CPU/bandwidth, so most of the processing has to take place on the server. I can think of a couple of methods to do this. All have trade-offs and at this point, I'm unsure which is the right course of action... Method 1: For change set n, store the "diff" of the current n and previous n-1. When a client with version y asks if there have been any changes, send the change sets from version y up to the current version. e.g. added item 334, contents: xxx. Deleted picture 44. Deleted PDF 11. Changed 33. added picture 99. Characteristics: Diffs take up space, although in theory would be kept small. However, all diffs must be kept around indefinitely (should a v1 app have not been updated for a year, must apply v2..v100). High latency devices (mobile apps) will incur a penalty to send lots of small files (assume cannot be zipped or tarr'd up into one file) Very few server CPU resources required, as all it does is send the client a list of files "Dumb" - if I change an item in change set 3, and change it to something else in 4, the client is going to perform both actions, even though #3 is rendered moot by #4. Or, if an asset is added in #4 and removed in #5 - the client will download a file just to delete it later. Method 2: Very similar to method 1 except on the server, do some sort of a diff between the change sets represented by the app version and server version. Package that up and send that single change set to the client. Characteristics: Client-efficient: The client only has to process one file, duplicate or irrelevant changes are stripped out. Server CPU/space intensive. The change sets must be diff'd and then written out to a file that is then sent to the client. Makes diff server scalability an issue. Possibly ways to cache the results and re-use them, but in the wild there's likely to be a lot of different versions so the diff re-use has a limit Diff algorithm is complicated. The change sets must be structured in such a way that an efficient and effective diff can be performed. Method 3: Instead of keeping diffs, write out the entire versioned asset collection to a mobile-database import file. When client requests an update, send the entire database to client and have them update their assets appropriately. Characteristics: Conceptually simple -- easy to develop and deploy Very inefficient as the client database is restored every update. If only one new thing was added, the whole database is refreshed. Server space and CPU efficient. Only the latest version DB needs kept around and the server just throws the file to the client. Others?? Thoughts? Thanks!!

Flushing a queue using AMQP, Rabbit, and Ruby

- by jeffshantz

I'm developing a system in Ruby that is going to make use of RabbitMQ to send messages to a queue as it does some work. I am using: Ruby 1.9.1 Stable RabbitMQ 1.7.2 AMQP gem v0.6.7 (http://github.com/tmm1/amqp) Most of the examples I have seen on this gem have their publish calls in an EM.add_periodic_timer block. This doesn't work for what I suspect is a vast majority of use cases, and certainly not for mine. I need to publish a message as I complete some work, so putting a publish statement in an add_periodic_timer block doesn't suffice. So, I'm trying to figure out how to publish a few messages to a queue, and then "flush" it, so that any messages I've published are then delivered to my subscribers. To give you an idea of what I mean, consider the following publisher code: #!/usr/bin/ruby require 'rubygems' require 'mq' MESSAGES = ["hello","goodbye","test"] AMQP.start do queue = MQ.queue('testq') messages_published = 0 while (messages_published < 50) if (rand() < 0.4) message = MESSAGES[rand(MESSAGES.size)] puts "#{Time.now.to_s}: Publishing: #{message}" queue.publish(message) messages_published += 1 end sleep(0.1) end AMQP.stop do EM.stop end end So, this code simply loops, publishing a message with 40% probability on each iteration of the loop, and then sleeps for 0.1 seconds. It does this until 50 messages have been published, and then stops AMQP. Of course, this is just a proof of concept. Now, my subscriber code: #!/usr/bin/ruby require 'rubygems' require 'mq' AMQP.start do queue = MQ.queue('testq') queue.subscribe do |header, msg| puts "#{Time.now.to_s}: Received #{msg}" end end So, we just subscribe to the queue, and for each message received, we print it out. Great, except that the subscriber only receives all 50 messages when the publisher calls AMQP.stop. Here's the output from my publisher. It has been truncated in the middle for brevity: $ ruby publisher.rb 2010-04-14 21:45:42 -0400: Publishing: test 2010-04-14 21:45:42 -0400: Publishing: hello 2010-04-14 21:45:42 -0400: Publishing: test 2010-04-14 21:45:43 -0400: Publishing: test 2010-04-14 21:45:44 -0400: Publishing: test 2010-04-14 21:45:44 -0400: Publishing: goodbye 2010-04-14 21:45:45 -0400: Publishing: goodbye 2010-04-14 21:45:45 -0400: Publishing: test 2010-04-14 21:45:45 -0400: Publishing: test . . . 2010-04-14 21:45:55 -0400: Publishing: test 2010-04-14 21:45:55 -0400: Publishing: test 2010-04-14 21:45:55 -0400: Publishing: test 2010-04-14 21:45:55 -0400: Publishing: goodbye Next, the output from my subscriber: $ ruby consumer.rb 2010-04-14 21:45:56 -0400: Received test 2010-04-14 21:45:56 -0400: Received hello 2010-04-14 21:45:56 -0400: Received test 2010-04-14 21:45:56 -0400: Received test 2010-04-14 21:45:56 -0400: Received test 2010-04-14 21:45:56 -0400: Received goodbye 2010-04-14 21:45:56 -0400: Received goodbye 2010-04-14 21:45:56 -0400: Received test 2010-04-14 21:45:56 -0400: Received test . . . 2010-04-14 21:45:56 -0400: Received test 2010-04-14 21:45:56 -0400: Received test 2010-04-14 21:45:56 -0400: Received test 2010-04-14 21:45:56 -0400: Received goodbye If you note the timestamps in the output, the subscriber only receives all of the messages once the publisher has stopped AMQP and exited. So, being an AMQP newb, how can I get my messages to deliver immediately? I tried putting AMQP.start and AMQP.stop in the body of the while loop of the publisher, but then only the first message gets delivered -- though strangely, if I turn on logging, there are no error messages reported by the server and the messages do get sent to the queue, but never get received by the subscriber. Suggestions would be much appreciated. Thanks for reading.

Google App Engine - Secure Cookies

- by tponthieux

I'd been searching for a way to do cookie based authentication/sessions in Google App Engine because I don't like the idea of memcache based sessions, and I also don't like the idea of forcing users to create google accounts just to use a website. I stumbled across someone's posting that mentioned some signed cookie functions from the Tornado framework and it looks like what I need. What I have in mind is storing a user's id in a tamper proof cookie, and maybe using a decorator for the request handlers to test the authentication status of the user, and as a side benefit the user id will be available to the request handler for datastore work and such. The concept would be similar to forms authentication in ASP.NET. This code comes from the web.py module of the Tornado framework. According to the docstrings, it "Signs and timestamps a cookie so it cannot be forged" and "Returns the given signed cookie if it validates, or None."

Apple push Notification Feedback service Not working

- by Yassmeen

Hi, I am developing an iPhone App that uses Apple Push Notifications. On the iPhone side everything is fine, on the server side I have a problem. Notifications are sent correctly however when I try to query the feedback service to obtain a list of devices from which the App has been uninstalled, I always get zero results. I know that I should obtain one result as the App has been uninstalled from one of my test devices. After 24 hours and more I still have no results from the feedback service.. Any ideas? Does anybody know how long it takes for the feedback service to recognize that my App has been uninstalled from my test device? Note: I have another push notification applications on the device so I know that my app is not the only app. The code - C#: public static string CheckFeedbackService(string certaName, string hostName) { SYLogger.Log("Check Feedback Service Started"); ServicePointManager.ServerCertificateValidationCallback = new RemoteCertificateValidationCallback(ValidateServerCertificate); // Create a TCP socket connection to the Apple server on port 2196 TcpClient tcpClientF = null; SslStream sslStreamF = null; string result = string.Empty; //Contect to APNS& Add the Apple cert to our collection X509Certificate2Collection certs = new X509Certificate2Collection { GetServerCert(certaName) }; //Set up byte[] buffer = new byte[38]; int recd = 0; DateTime minTimestamp = DateTime.Now.AddYears(-1); // Create a TCP socket connection to the Apple server on port 2196 try { using (tcpClientF = new TcpClient(hostName, 2196)) { SYLogger.Log("Client Connected ::" + tcpClientF.Connected); // Create a new SSL stream over the connection sslStreamF = new SslStream(tcpClientF.GetStream(), true,ValidateServerCertificate); // Authenticate using the Apple cert sslStreamF.AuthenticateAsClient(hostName, certs, SslProtocols.Default, false); SYLogger.Log("Stream Readable ::" + sslStreamF.CanRead); SYLogger.Log("Host Name ::"+hostName); SYLogger.Log("Cert Name ::" + certs[0].FriendlyName); if (sslStreamF != null) { SYLogger.Log("Connection Started"); //Get the first feedback recd = sslStreamF.Read(buffer, 0, buffer.Length); SYLogger.Log("Buffer length ::" + recd); //Continue while we have results and are not disposing while (recd > 0) { SYLogger.Log("Reading Started"); //Get our seconds since 1970 ? byte[] bSeconds = new byte[4]; byte[] bDeviceToken = new byte[32]; Array.Copy(buffer, 0, bSeconds, 0, 4); //Check endianness if (BitConverter.IsLittleEndian) Array.Reverse(bSeconds); int tSeconds = BitConverter.ToInt32(bSeconds, 0); //Add seconds since 1970 to that date, in UTC and then get it locally var Timestamp = new DateTime(1970, 1, 1, 0, 0, 0, DateTimeKind.Utc).AddSeconds(tSeconds).ToLocalTime(); //Now copy out the device token Array.Copy(buffer, 6, bDeviceToken, 0, 32); string deviceToken = BitConverter.ToString(bDeviceToken).Replace("-", "").ToLower().Trim(); //Make sure we have a good feedback tuple if (deviceToken.Length == 64 && Timestamp > minTimestamp) { SYLogger.Log("Feedback " + deviceToken); result = deviceToken; } //Clear array to reuse it Array.Clear(buffer, 0, buffer.Length); //Read the next feedback recd = sslStreamF.Read(buffer, 0, buffer.Length); } SYLogger.Log("Reading Ended"); } } } catch (Exception e) { SYLogger.Log("Authentication failed - closing the connection::" + e); return "NOAUTH"; } finally { // The client stream will be closed with the sslStream // because we specified this behavior when creating the sslStream. if (sslStreamF != null) sslStreamF.Close(); if (tcpClientF != null) tcpClientF.Close(); //Clear array on error Array.Clear(buffer, 0, buffer.Length); } SYLogger.Log("Feedback ended "); return result; }

How to solve a deallocated connection in iPhone SDK 3.1.3? - Streams - CFSockets

- by Christian

Hi everyone, Debugging my implementation I found a memory leak issue. I know where is the issue, I tried to solve it but sadly without success. I will try to explain you, maybe someone of you can help with this. First I have two classes involved in the issue, the publish class (where publishing the service and socket configuration is done) and the connection (where the socket binding and the streams configuration is done). The main issue is in the connection via native socket. In the 'publish' class the "server" accepts a connection with a callback. The callback has the native-socket information. Then, a connection with native-socket information is created. Next, the socket binding and the streams configuration is done. When those actions are successful the instance of the connection is saved in a mutable array. Thus, the connection is established. static void AcceptCallback(CFSocketRef socket, CFSocketCallBackType type, CFDataRef address, const void *data, void *info) { Publish *rePoint = (Publish *)info; if ( type != kCFSocketAcceptCallBack) { return; } CFSocketNativeHandle nativeSocketHandle = *((CFSocketNativeHandle *)data); NSLog(@"The AcceptCallback was called, a connection request arrived to the server"); [rePoint handleNewNativeSocket:nativeSocketHandle]; } - (void)handleNewNativeSocket:(CFSocketNativeHandle)nativeSocketHandle{ Connection *connection = [[[Connection alloc] initWithNativeSocketHandle:nativeSocketHandle] autorelease]; // Create the connection if (connection == nil) { close(nativeSocketHandle); return; } NSLog(@"The connection from the server was created now try to connect"); if ( ! [connection connect]) { [connection close]; return; } [clients addObject:connection]; //save the connection trying to avoid the deallocation } The next step is receive the information from the client, thus a read-stream callback is triggered with the information of the established connection. But when the callback-handler tries to use this connection the error occurs, it says that such connection is deallocated. The issue here is that I don't know where/when the connection is deallocated and how to know it. I am using the debugger, but after some trials, I don't see more info. void myReadStreamCallBack (CFReadStreamRef stream, CFStreamEventType eventType, void *info) { NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init]; Connection *handlerEv = [[(Connection *)info retain] autorelease]; // The error -[Connection retain]: message sent to deallocated instance 0x1f5ef0 (Where 0x1f5ef0 is the reference to the established connection) [handlerEv readStreamHandleEvent:stream andEvent:eventType]; [pool drain]; } void myWriteStreamCallBack (CFWriteStreamRef stream, CFStreamEventType eventType, void *info){ NSAutoreleasePool *p = [[NSAutoreleasePool alloc] init]; Connection *handlerEv = [[(Connection *)info retain] autorelease]; //Sometimes the error also happens here, I tried without the pool, but it doesn't help neither. [handlerEv writeStreamHandleEvent:eventType]; [p drain]; } Something strange is that when I run the debugger(with breakpoints) everything goes well, the connection is not deallocated and the callbacks work fine and the server is able to receive the message. I will appreciate any hint!

Issue with Silverlight interop with JBoss WebService

- by Hadi Eskandari

I have a simple JAXWS webservice deployed in JBoss. It runs fine with a java client but I'm trying to connect using a Silverlight 3.0 application. I've changed the webservice to use Soap 1.1: @BindingType(value = "http://schemas.xmlsoap.org/wsdl/soap/http") public class UserSessionBean implements UserSessionRemote { ... } I'm using BasicHttpBinding on the Silverlight client. There are two issues: 1- When I connect from VisualStudio (2008 and 2010) to create the webservice proxies, the following exception is thrown, but the proxy is generated successfully. This also happens when I try to update the existing web service reference (but it also updates fine). com.sun.xml.ws.server.UnsupportedMediaException: Unsupported Content-Type: application/soap+xml; charset=utf-8 Supported ones are: [text/xml] at com.sun.xml.ws.encoding.StreamSOAPCodec.decode(StreamSOAPCodec.java:291) at com.sun.xml.ws.encoding.StreamSOAPCodec.decode(StreamSOAPCodec.java:128) at com.sun.xml.ws.encoding.SOAPBindingCodec.decode(SOAPBindingCodec.java:287) at com.sun.xml.ws.transport.http.HttpAdapter.decodePacket(HttpAdapter.java:276) at com.sun.xml.ws.transport.http.HttpAdapter.access$500(HttpAdapter.java:93) at com.sun.xml.ws.transport.http.HttpAdapter$HttpToolkit.handle(HttpAdapter.java:432) at com.sun.xml.ws.transport.http.HttpAdapter.handle(HttpAdapter.java:244) at com.sun.xml.ws.transport.http.servlet.ServletAdapter.handle(ServletAdapter.java:135) at org.jboss.wsf.stack.metro.RequestHandlerImpl.doPost(RequestHandlerImpl.java:225) at org.jboss.wsf.stack.metro.RequestHandlerImpl.handleHttpRequest(RequestHandlerImpl.java:82) at org.jboss.wsf.common.servlet.AbstractEndpointServlet.service(AbstractEndpointServlet.java:85) at javax.servlet.http.HttpServlet.service(HttpServlet.java:803) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:290) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:206) at org.jboss.web.tomcat.filters.ReplyHeaderFilter.doFilter(ReplyHeaderFilter.java:96) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:235) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:206) at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:230) at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:175) at org.jboss.web.tomcat.security.SecurityAssociationValve.invoke(SecurityAssociationValve.java:182) at org.jboss.web.tomcat.security.JaccContextValve.invoke(JaccContextValve.java:84) at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:127) at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:102) at org.jboss.web.tomcat.service.jca.CachedConnectionValve.invoke(CachedConnectionValve.java:157) at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:109) at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:262) at org.apache.coyote.http11.Http11Processor.process(Http11Processor.java:844) at org.apache.coyote.http11.Http11Protocol$Http11ConnectionHandler.process(Http11Protocol.java:583) at org.apache.tomcat.util.net.JIoEndpoint$Worker.run(JIoEndpoint.java:446) at java.lang.Thread.run(Thread.java:619) 2- When I use the proxy to fetch some data from the webservice (even methods with primitive types), I get the following error on Silverlight client: "An error occurred while trying to make a request to URI 'http://localhost:9090/admintool/UserSessionEJB'. This could be due to attempting to access a service in a cross-domain way without a proper cross-domain policy in place, or a policy that is unsuitable for SOAP services. You may need to contact the owner of the service to publish a cross-domain policy file and to ensure it allows SOAP-related HTTP headers to be sent. This error may also be caused by using internal types in the web service proxy without using the InternalsVisibleToAttribute attribute. Please see the inner exception for more details." Setting a breakpoint on my java code, I can see that it is not hit when I run the silverlight client, so it is probably a cross domain issue, but I'm not sure how to handle it (I've already created a crossdomain.xml file and put it beside my HTML page hosting the silverlight client). I appreciate any help!

WinQual: Why would WER not accept code-signing certificates?

- by Ian Boyd

In 2005 i tried to establish a WinQual account with Microsoft, so i could pick up our (if any) crash dump files submitted automatically through Windows Error Reporting (WER). i was not allowed to have my crash dumps, because i don't have a Verisign certificate. Instead i have a cheaper one, generated by a Verisign subsidiary: Thawte. The method in which you join is: you digitally sign a sample exe they provide. This proves that you are the same signer that signed apps that they got crash dumps from in the wild. Cryptographically, the private key is needed to generate a digital signature on an executable. Only the holder of that private key can create a signature with for the matching public key. It doesn't matter who generated that private key. That includes certificates that are generated from: self-signing Wells Fargo DigiCert SecureTrust Trustware QuoVadis GoDaddy Entrust Cybertrust GeoTrust GlobalSign Comodo Thawte Verisign Yet Microsof's WinQual only accepts digital certificates generated by Verisign. Not even Verisign's subsidiaries are good enough (Thawte). Can anyone think of any technical, legal or ethical reason why Microsoft doesn't want to accept code-signing certificates? The WinQual site says: Why Is a Digital Certificate Required for Winqual Membership? A digital certificate helps protect your company from individuals who seek to impersonate members of your staff or who would otherwise commit acts of fraud against your company. Using a digital certificate enables proof of an identity for a user or an organization. Is somehow a Thawte digital certificate not secure? Two years later, i sent a reminder notice to WinQual that i've been waiting to be able to get at my crash dumps. The response from WinQual team was: Hello, Thanks for the reminder. We have notified the appropriate people that this is still a request. In 2008 i asked this question in a Microsoft support forum, and the response was: We are only setup to accept VeriSign Certificates at this point. We have not had an overwhelming demand to support other types of certificates. What can it possibly mean to not be "setup" to accept other kinds of certificates? If the thumbprint of the key that signed the WinQual.exe test app is the same as the thumbprint that signed the executable who's crash dump you got in the wild: it is proven - they are my crash dumps, give them to me. And it's not like there's a special API to check if a Verisign digital signature is valid, as opposed to all other digital signatures. A valid signature is valid no matter who generated the key. Microsoft is free to not trust the signer, but that's not the same as identity. So that is my question, can anyone think of any practical reason why WinQual isn't setup to support digital signatures? One person theorized that the answer is that they're just lazy: Not that I know but I would assume that the team running the winQual system is a live team and not a dev team - as in, personality and skillset geared towards maintenance of existing systems. I could be wrong though. They don't want to do work to change it. But can anyone think of anything that would need to be changed? It's the same logic no matter what generated the key: "does the thumbprint match". What am i missing?

postfix 5.7.1 Relay access denied when sending mail with cron

- by zensys

Reluctant to ask because there is so much here about 'postfix relay access denied' but I cannot find my case: I use php (Zend Framework) to send emails outside my network using the Google mail server because I could not send mail outside my server (user: web). However when I sent out an email via cron (user: root, I believe), still using ZF, using the same mail config/credentials, I get the message: '5.7.1 Relay access denied' I guess I need to know one of two things: 1. How can I use the google smtp server from cron 2. What do I need to change in my config to send mail using my own server instead of google Though the answer to 2. is the more structural solution I assume, I am quite happy with an answer to 1. as well because I think Google is better at server maintaince (security/spam) than I am. Below my ZF application.ini mail section, main.cf and master.cf: application.ini: resources.mail.transport.type = smtp resources.mail.transport.auth = login resources.mail.transport.host = "smtp.gmail.com" resources.mail.transport.ssl = tls resources.mail.transport.port = 587 resources.mail.transport.username = [email protected] resources.mail.transport.password = xxxxxxx resources.mail.defaultFrom.email = [email protected] resources.mail.defaultFrom.name = "my company" main.cf: # Debian specific: Specifying a file name will cause the first # line of that file to be used as the name.

500 Internal Server Error with PHP application

- by James

I have written a PHP application using Windows and XAMPP. I've been trying to run it on Ubuntu 10.10 with Lighttpd 1.4.26. Parts of the application work fine, but whenever I try to log in, I get a 500 - Internal Server Error page. The only thing that shows up in /var/log/lighttpd/error.log is 2011-02-25 13:43:13: (mod_fastcgi.c.2582) unexpected end-of-file (perhaps the fastcgi process died): pid: 1169 socket: unix:/tmp/php.socket-0 2011-02-25 13:43:13: (mod_fastcgi.c.3367) response not received, request sent: 1596 on socket: unix:/tmp/php.socket-0 for /~denton/customer-facing-portal/index.php?, closing connection If I had any output whatsoever from PHP, this would be a lot easier to debug.

TableViewCell autorelease error

- by iAm

OK, for two days now i have been trying to solve an error i have inside the cellForRowAtIndex method, let start by saying that i have tracked down the bug to this method, the error is [CFDictionary image] or [Not a Type image] message sent to deallocated instance. I know about the debug flags, NSZombie, MallocStack, and others, they helped me narrow it down to this method and why, but I do not know how to solve besides a redesign of the app UI. SO what am i trying to do, well for this block of code, displays a purchase detail, which contains items, the items are in there own section, now when in edit mode, there appears a cell at the bottom of the items section with a label of "Add new Item", and this button will present a modal view of the add item controller, item is added and the view returns to the purchase detail screen, with the just added item in the section just above the "add new Item" cell, the problem happens when i scroll the item section off screen and back into view the app crashes with EXC_BAD_ACCESS, or even if i don't scroll and instead hit the back button on the navBar, still the same error. - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { UITableViewCell *cell = nil; switch (indexPath.section) { case PURCHASE_SECTION: { static NSString *cellID = @"GenericCell"; cell = [tableView dequeueReusableCellWithIdentifier:cellID]; if (cell == nil) { cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleValue2 reuseIdentifier:cellID] autorelease]; cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator; } switch (indexPath.row) { case CATEGORY_ROW: cell.textLabel.text = @"Category:"; cell.detailTextLabel.text = [self.purchase.category valueForKey:@"name"]; cell.accessoryType = UITableViewCellAccessoryNone; cell.editingAccessoryType = UITableViewCellAccessoryDisclosureIndicator; break; case TYPE_ROW: cell.textLabel.text = @"Type:"; cell.detailTextLabel.text = [self.purchase.type valueForKey:@"name"]; cell.accessoryType = UITableViewCellAccessoryNone; cell.editingAccessoryType = UITableViewCellAccessoryDisclosureIndicator; break; case VENDOR_ROW: cell.textLabel.text = @"Payment:"; cell.detailTextLabel.text = [self.purchase.vendor valueForKey:@"name"]; cell.accessoryType = UITableViewCellAccessoryNone; cell.editingAccessoryType = UITableViewCellAccessoryDisclosureIndicator; break; case NOTES_ROW: cell.textLabel.text = @"Notes"; cell.editingAccessoryType = UITableViewCellAccessoryNone; break; default: break; } break; } case ITEMS_SECTION: { NSUInteger itemsCount = [items count]; if (indexPath.row < itemsCount) { static NSString *itemsCellID = @"ItemsCell"; cell = [tableView dequeueReusableCellWithIdentifier:itemsCellID]; if (cell == nil) { cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:itemsCellID] autorelease]; cell.accessoryType = UITableViewCellAccessoryNone; } singleItem = [self.items objectAtIndex:indexPath.row]; cell.textLabel.text = singleItem.name; cell.detailTextLabel.text = [singleItem.amount formattedDataDisplay]; cell.imageView.image = [singleItem.image image]; } else { static NSString *AddItemCellID = @"AddItemCell"; cell = [tableView dequeueReusableCellWithIdentifier:AddItemCellID]; if (cell == nil) { cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:AddItemCellID] autorelease]; cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator; } cell.textLabel.text = @"Add Item"; } break; } case LOCATION_SECTION: { static NSString *localID = @"LocationCell"; cell = [tableView dequeueReusableCellWithIdentifier:localID]; if (cell == nil) { cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:localID] autorelease]; cell.accessoryType = UITableViewCellAccessoryNone; } cell.textLabel.text = @"Purchase Location"; cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator; cell.editingAccessoryType = UITableViewCellAccessoryNone; break; } default: break; } return cell; } the singleItem is of Modal Type PurchaseItem for core data now that i know what is causing the error, how do i solve it, I have tried everything that i know and some of what i dont know but still, no progress, please any suggestions as to how to solve this without redesign is my goal, perhaps there is an error i am doing that I cannot see, but if it's the nature of autorelease, than i will redesign.

Case 1 If I run below command i.e iperf in UL only, then i am able to capture the o/p in txt file @output = readpipe("iperf.exe -u -c 127.0.0.1 -p 5001 -b 3600k -t 10 -i 1"); open FILE, ">Misplay_DL.txt" or die $!; print FILE @output; close FILE; Case 2 When I run iperf in DL mode , as we know server will start listening in cont. mode like below even after getting data from client (Here i am using server and client on LAN) @output = system("iperf.exe -u -s -p 5001 -i 1"); on server side: D:\_IOT_SESSION_RELATED\SEEM_ELEMESNTS_AT_COMM_PORT_CONF\Tput_Related_Tools\AUTO MATION_APP_\AUTOMATION_UTILITYiperf.exe -u -s -p 5001 ------------------------------------------------------------ Server listening on UDP port 5001 Receiving 1470 byte datagrams UDP buffer size: 8.00 KByte (default) ------------------------------------------------------------ [1896] local 192.168.5.101 port 5001 connected with 192.168.5.101 port 4878 [ ID] Interval Transfer Bandwidth Jitter Lost/Total Datagrams [1896] 0.0- 2.0 sec 881 KBytes 3.58 Mbits/sec 0.000 ms 0/ 614 (0%) command prompt does not appear , process is contd... on client side: D:\_IOT_SESSION_RELATED\SEEM_ELEMESNTS_AT_COMM_PORT_CONF\Tput_Related_Tools\AUTO MATION_APP_\AUTOMATION_UTILITYiperf.exe -u -c 192.168.5.101 -p 5001 -b 3600k -t 2 -i 1 ------------------------------------------------------------ Client connecting to 192.168.5.101, UDP port 5001 Sending 1470 byte datagrams UDP buffer size: 8.00 KByte (default) ------------------------------------------------------------ [1880] local 192.168.5.101 port 4878 connected with 192.168.5.101 port 5001 [ ID] Interval Transfer Bandwidth [1880] 0.0- 1.0 sec 441 KBytes 3.61 Mbits/sec [1880] 1.0- 2.0 sec 439 KBytes 3.60 Mbits/sec [1880] 0.0- 2.0 sec 881 KBytes 3.58 Mbits/sec [1880] Server Report: [1880] 0.0- 2.0 sec 881 KBytes 3.58 Mbits/sec 0.000 ms 0/ 614 (0%) [1880] Sent 614 datagrams D:\_IOT_SESSION_RELATED\SEEM_ELEMESNTS_AT_COMM_PORT_CONF\Tput_Related_Tools\AUTO MATION_APP_\AUTOMATION_UTILITY so with this as server is cont. listening and never terminates so can't take output of server side to a txt file as it is going to the next command itself to create a txt file so i adopted the alarm() function to terminate the server side (iperf.exe -u -s -p 5001) commands after it received all data from the client. could anybody suggest me the way.. Here is my code: #! /usr/bin/perl -w my $command = "iperf.exe -u -s -p 5001"; my @output; eval { local $SIG{ALRM} = sub { die "Timeout\n" }; alarm 20; #@output = `$command`; #my @output = readpipe("iperf.exe -u -s -p 5001"); #my @output = exec("iperf.exe -u -s -p 5001"); my @output = system("iperf.exe -u -s -p 5001"); alarm 0; }; if ($@) { warn "$command timed out.\n"; } else { print "$command successful. Output was:\n", @output; } open FILE, ">display.txt" or die $!; print FILE @output_1; close FILE; i know that with system command i cannot capture the o/p to a txt file but i tried with readpipe() and exec() calls also but in vain... could some one please take a look and let me know why the iperf.exe -u -s -p 5001 is not terminating even after the alarm call and to take the out put to a txt file

Outlook Plug-In for custom CRM

- by Optimal Solutions

I would like to write a plug-in that will allow a custom written CRM to read and write to their local Outlook client. I know that this poses a security concern. But, my clients are asking that their CRM "be connected" to Outlook. They would like to be able to do the following: A) When a contact sends them an email (reply or free standing email), they'd like the details of this email to go INTO the CRM. Yep. They would like me to save the body, time and date it was sent, etc. B) They want to be able to send new emails (or replies to existing emails) from within the CRM itself. Basically, "a form that looks like Outlook's send/reply email form". C) Want the ability to search for contacts and the related emails with a search for tags/keywords facility. (i.e. if a product name or code appears in an email then they want the email returned in the search). D) Having performed a search of many contacts, they will want to prepare a mailer and shoot out some sort of email announcement to their qualified leads. This could be 50, 100, or more persons. So its got to be able to allow bulk mailing. E) Given a list of new prospects, that arent currently contacts in the CRM, they will want to do the same and if they get replies from this mailer to the prospects, the will want the replies to be saved in the DB and contacts be inserted into the DB. F) They would like to be able to utilize the calendar and task list facilities of Outlook from the CRM, as well. More or less, they want this pretty basic (as it is today) CRM that I created to integrate with Outlook and have it do so seamlessly as if it was an add-on to the CRM. A plug-in is what I am thinking... But, I dont know where to begin. My environment is Windows XP/Vista and is going to be ASP.NET and I am going to use the VB.NET language to accomplish this. What do I need? Are there resources out there that can describe how to build a plug-in to Outlook as I have been asked to? This is not Exchange, none of the clients use exchange (not so far). They all run Outlook. Mostly 2003. Most clients are XP right now but some are upgrading to Vista. For some reason I cant seem to wrap my head around this. I think the whole security issue is thwarting my ability to see past what is probably a simple thing. The client doesnt want to be prompted by any security messages asking them if they are sure they want to send 382 emails to their contacts. Not once and certainly not 382 times. Where do I begin? I've searched the internet for similar but mainly what I found are already-written products and I've got to write this from scratch.

BasicAuthProvider in ServiceStack

- by Per

I've got an issue with the BasicAuthProvider in ServiceStack. POST-ing to the CredentialsAuthProvider (/auth/credentials) is working fine. The problem is that when GET-ing (in Chrome): http://foo:pwd@localhost:81/tag/string/list the following is the result Handler for Request not found: Request.HttpMethod: GET Request.HttpMethod: GET Request.PathInfo: /login Request.QueryString: System.Collections.Specialized.NameValueCollection Request.RawUrl: /login?redirect=http%3a%2f%2flocalhost%3a81%2ftag%2fstring%2flist which tells me that it redirected me to /login instead of serving the /tag/... request. Here's the entire code for my AppHost: public class AppHost : AppHostHttpListenerBase, IMessageSubscriber { private ITagProvider myTagProvider; private IMessageSender mySender; private const string UserName = "foo"; private const string Password = "pwd"; public AppHost( TagConfig config, IMessageSender sender ) : base( "BM App Host", typeof( AppHost ).Assembly ) { myTagProvider = new TagProvider( config ); mySender = sender; } public class CustomUserSession : AuthUserSession { public override void OnAuthenticated( IServiceBase authService, IAuthSession session, IOAuthTokens tokens, System.Collections.Generic.Dictionary<string, string> authInfo ) { authService.RequestContext.Get<IHttpRequest>().SaveSession( session ); } } public override void Configure( Funq.Container container ) { Plugins.Add( new MetadataFeature() ); container.Register<BeyondMeasure.WebAPI.Services.Tags.ITagProvider>( myTagProvider ); container.Register<IMessageSender>( mySender ); Plugins.Add( new AuthFeature( () => new CustomUserSession(), new AuthProvider[] { new CredentialsAuthProvider(), //HTML Form post of UserName/Password credentials new BasicAuthProvider(), //Sign-in with Basic Auth } ) ); container.Register<ICacheClient>( new MemoryCacheClient() ); var userRep = new InMemoryAuthRepository(); container.Register<IUserAuthRepository>( userRep ); string hash; string salt; new SaltedHash().GetHashAndSaltString( Password, out hash, out salt ); // Create test user userRep.CreateUserAuth( new UserAuth { Id = 1, DisplayName = "DisplayName", Email = "[email protected]", UserName = UserName, FirstName = "FirstName", LastName = "LastName", PasswordHash = hash, Salt = salt, }, Password ); } } Could someone please tell me what I'm doing wrong with either the SS configuration or how I am calling the service, i.e. why does it not accept the supplied user/pwd?

How do I send an email with embedded images AND regular attachments in JavaMail?

- by Chris

Hi, I'd like to know how to build an SMTP multipart message in the correct order so that it will render correctly on the iPhone mail client (rendering correctly in GMail). I'm using Javamail to build up an email containing the following parts: A body part with content type "text/html; UTF-8" An embedded image attachment. A file attachment I am sending the mail via GMail SMTP (via SSL) and the mail is sent and rendered correctly using a GMail account, however, the mail does not render correctly on the iPhone mail client. On the iPhone mail client, the image is rendered before the "Before Image" text when it should be rendered afterwards. After the "Before Image" text there is an icon with a question mark (I assume it means it couldn't find the referenced CID). I'm not sure if this is a limitation of the iPhone mail client or a bug in my mail sending code (I strongly assume the latter). I think that perhaps the headers on my parts might by incorrect or perhaps I am providing the multiparts in the wrong order. I include the text of the received mail as output by gmail (which renders the file correc Message-ID: <[email protected]> Subject: =?UTF-8?Q?Test_from_=E3=82=AF=E3=83=AA=E3=82=B9?= MIME-Version: 1.0 Content-Type: multipart/mixed; boundary="----=_Part_0_20870565.1274154021755" ------=_Part_0_20870565.1274154021755 Content-Type: application/octet-stream Content-Transfer-Encoding: base64 Content-ID: <20100518124021763_368238_0> iVBORw0K ----- TRIMMED FOR CONCISENESS 6p1VVy4alAAAAABJRU5ErkJggg== ------=_Part_0_20870565.1274154021755 Content-Type: text/html; charset=UTF-8 Content-Transfer-Encoding: 7bit <html><head><title>Employees Favourite Foods</title> <style> body { font: normal 8pt arial; } th { font: bold 8pt arial; white-space: nowrap; } td { font: normal 8pt arial; white-space: nowrap; } </style></head><body> Before Image<br><img src="cid:20100518124021763_368238_0"> After Image<br><table border="0"> <tr> <th colspan="4">Employees Favourite Foods</th> </tr> <tr> <th align="left">Name</th><th align="left">Age</th><th align="left">Tel.No</th><th align="left">Fav.Food</th> </tr> <tr style="background-color:#e0e0e0"> <td>Chris</td><td>34</td><td>555-123-4567</td><td>Pancakes</td> </tr> </table></body></html> ------=_Part_0_20870565.1274154021755 Content-Type: text/plain; charset=us-ascii; name=textfile.txt Content-Transfer-Encoding: 7bit Content-Disposition: attachment; filename=textfile.txt This is a textfile with numbers counting from one to ten beneath this line: one two three four five six seven eight nine ten(no trailing carriage return) ------=_Part_0_20870565.1274154021755-- Even if you can't assist me with this, I would appreciate it if any members of the forum could forward me a (non-personal) mail that includes inline images (not external hyperlinked images though).

How to load and pass a Xforms form in Orbeon (How to Send instance to XForms) ?

- by Clem

Hi, I am using the Orbeon Forms solution to generate messages from filled-in web forms. I read different code snippetse in Orbeon's wiki on XForms submission from a pipeline, and I tried different solutions but it doesn't work, and there is no example with a POST from a pipeline, caught by a PFC and sent to an XForms view that receives the posted data (all examples are done in the same page). I have the following pipeline which is received on his instance input: pipelineWrite.xpl <p:config ...> <p:param name="instance" type="input"/>  <p:param name="data" type="output"/> <p:processor name="oxf:java">  <p:input name="config"> <config sourcepath="." class="ProcessorWriteCUSDECCD001B"/> </p:input> <p:input name="input" href="#instance"/> <p:output name="output" id="file"/>  </p:processor> <p:processor name="oxf:xforms-submission">  <p:input name="submission"> <xforms:submission method="post" action="/CUSDECCD001B/success" /> </p:input> <p:input name="request" href="#file"/> <p:output name="response" ref="data"/> </p:processor> </p:config> Then there is the PFC which catch the actions : page-flow.xml <config xmlns="http://www.orbeon.com/oxf/controller"> <page path-info="/CUSDECCD001B/" view="View/ViewForm.xhtml"/>  <page path-info="/CUSDECCD001B/write" model="Controller/PipelineWrite.xpl"/>  <page path-info="/CUSDECCD001B/success" view="View/ViewSuccess.xhtml"/>  <epilogue url="oxf:/config/epilogue.xpl"/> </config> Then there is the success view, which is very simple : ViewSuccess.xhtml <html ... > <head> <title>Generation OK</title> <xforms:model> <xforms:instance id="FILE" src="input:instance"> <files xmlns=""> <file mediaType="" filename="" size="" /> </files> </xforms:instance> </xforms:model> </head> <body> Click here to download : <xforms:output ref="//file" appearance="xxforms:download"> <xforms:filename ref="@filename"/> <xforms:mediatype ref="@mediatype"/> <xforms:label>Download</xforms:label> </xforms:output> </body> </html> The problem is that the post is done well, the PFC catches the action well, load the correct view, but the view is loaded with no data (the view doesn't find the data on his instance input). I tried with a GET in the view to retrieve the POST data, and that's the same thing. No data is retrieved. So the download button doesn't work. I hope I'm clear enough to find a solution. Thanks in advance.

Reading email address from contacts fails with weird memory issue - Solved

- by CapsicumDreams

Hi all, I'm stumped. I'm trying to get a list of all the email address a person has. I'm using the ABPeoplePickerNavigationController to select the person, which all seems fine. I'm setting my ABRecordRef personDealingWith; from the person argument to - (BOOL)peoplePickerNavigationController:(ABPeoplePickerNavigationController *)peoplePicker shouldContinueAfterSelectingPerson:(ABRecordRef)person property:(ABPropertyID)property identifier:(ABMultiValueIdentifier)identifier { and everything seems fine up till this point. The first time the following code executes, all is well. When subsequently run, I can get issues. First, the code: // following line seems to make the difference (issue 1) // NSLog(@"%d", ABMultiValueGetCount(ABRecordCopyValue(personDealingWith, kABPersonEmailProperty))); // construct array of emails ABMultiValueRef multi = ABRecordCopyValue(personDealingWith, kABPersonEmailProperty); CFIndex emailCount = ABMultiValueGetCount(multi); if (emailCount > 0) { // collect all emails in array for (CFIndex i = 0; i < emailCount; i++) { CFStringRef emailRef = ABMultiValueCopyValueAtIndex(multi, i); [emailArray addObject:(NSString *)emailRef]; CFRelease(emailRef); } } // following line also matters (issue 2) CFRelease(multi); If compiled as written, the are no errors or static analysis problems. This crashes with a *** -[Not A Type retain]: message sent to deallocated instance 0x4e9dc60 error. But wait, there's more! I can fix it in either of two ways. Firstly, I can uncomment the NSLog at the top of the function. I get a leak from the NSLog's ABRecordCopyValue every time through, but the code seems to run fine. Also, I can comment out the CFRelease(multi); at the end, which does exactly the same thing. Static compilation errors, but running code. So without a leak, this function crashes. To prevent a crash, I need to haemorrhage memory. Neither is a great solution. Can anyone point out what's going on? Solution: It turned out that I wasn't storing the ABRecordRef personDealingWith var correctly. I'm still not sure how to do that properly, but instead of having the functionality in another routine (performed later), I'm now doing the grunt-work in the delegate method, and using the derived results at my leisure. The new (working) routine: - (BOOL)peoplePickerNavigationController:(ABPeoplePickerNavigationController *)peoplePicker shouldContinueAfterSelectingPerson:(ABRecordRef)person { // as soon as they select someone, return personDealingWithFullName = (NSString *)ABRecordCopyCompositeName(person); personDealingWithFirstName = (NSString *)ABRecordCopyValue(person, kABPersonFirstNameProperty); // construct array of emails [personDealingWithEmails removeAllObjects]; ABMutableMultiValueRef multi = ABRecordCopyValue(person, kABPersonEmailProperty); if (ABMultiValueGetCount(multi) > 0) { // collect all emails in array for (CFIndex i = 0; i < ABMultiValueGetCount(multi); i++) { CFStringRef emailRef = ABMultiValueCopyValueAtIndex(multi, i); [personDealingWithEmails addObject:(NSString *)emailRef]; CFRelease(emailRef); } } CFRelease(multi); return NO; }

How to create Large resumable download from a secured location .NET

- by Kelvin H

I need to preface I'm not a .NET coder at all, but to get partial functionality, I modified a technet chunkedfilefetch.aspx script that uses chunked Data Reading and writing Streamed method of doing file transfer, to get me half-way. iStream = New System.IO.FileStream(path, System.IO.FileMode.Open, _ IO.FileAccess.Read, IO.FileShare.Read) dataToRead = iStream.Length Response.ContentType = "application/octet-stream" Response.AddHeader("Content-Length", file.Length.ToString()) Response.AddHeader("Content-Disposition", "attachment; filename=" & filedownload) ' Read and send the file 16,000 bytes at a time. ' While dataToRead 0 If Response.IsClientConnected Then length = iStream.Read(buffer, 0, 16000) Response.OutputStream.Write(buffer, 0, length) Response.Flush() ReDim buffer(16000) ' Clear the buffer ' dataToRead = dataToRead - length Else ' Prevent infinite loop if user disconnects ' dataToRead = -1 End If End While This works great on files up to 2GB and is fully functioning now.. But only one problem it doesn't allow for resume. I took the original code called it fetch.aspx and pass an orderNUM through the URL. fetch.aspx&ordernum=xxxxxxx It then reads the filename/location from the database occording to the ordernumber, and chunks it out from a secured location NOT under the webroot. I need a way to make this resumable, by the nature of the internet and large files people always get disconnected and would like to resume where they left off. But any resumable articles i've read, assume the file is within the webroot.. ie. http://www.devx.com/dotnet/Article/22533/1954 Great article and works well, but I need to stream from a secured location. I'm not a .NET coder at all, at best i can do a bit of coldfusion, if anyone could help me modify a handler to do this, i would really appreciate it. Requirements: I Have a working fetch.aspx script that functions well and uses the above code snippet as a base for the streamed downloading. Download files are large 600MB and are stored in a secured location outside of the webroot. Users click on the fetch.aspx to start the download, and would therefore be clicking it again if it was to fail. If the ext is a .ASPX and the file being sent is a AVI, clicking on it would completely bypass an IHTTP handler mapped to .AVI ext, so this confuses me From what I understand the browser will read and match etag value and file modified date to determine they are talking about the same file, then a subsequent accept-range is exchanged between the browser and IIS. Since this dialog happens with IIS, we need to use a handler to intercept and respond accordingly, but clicking on the link would send it to an ASPX file which the handeler needs to be on an AVI fiel.. Also confusing me. If there is a way to request the initial HTTP request header containing etag, accept-range into the normal .ASPX file, i could read those values and if the accept-range and etag exist, start chunking at that byte value somehow? but I couldn't find a way to transfer the http request headers since they seem to get lost at the IIS level. OrderNum which is passed in the URL string is unique and could be used as the ETag Response.AddHeader("ETag", request("ordernum")) Files need to be resumable and chunked out due to size. File extensions are .AVI so a handler could be written around it. IIS 6.0 Web Server Any help would really be appreciated, i've been reading and reading and downloading code, but none of the examples given meet my situation with the original file being streamed from outside of the webroot. Please help me get a handle on these httphandlers :)
