• FileNotFoundException when running WiX CustomAction with COMAdmin interop

  - by dabcabc

  I am trying to create a WiX custom action which will allow me to shutdown and clear down a COM+ package as part of an upgrade installation, or create and configure a new COM+ package as part of the initial installation. I previously had this running as a CustomAction within a standard Visual Studio MSI but this only allows the custom action to be executed after the files have been copied - which will fail as the package will still be running. The COMAdmin.dll has been added as a reference to the CustomAction project and is set CopyLocal=true. In the bin folder for the custom action project the Interop.COMAdmin.dll is present. The answer to this question seems to suggest that it should work. I am getting the following exception within the MSI log when trying to install: MSI (s) (C4:04) [10:40:34:205]: Invoking remote custom action.

• [SOLVED] BitmapFactory.decodeStream returning null when options are set.

  - by Robert Foss

  Hi! I'm having issues with BitmapFactory.decodeStream(inputStream). When using it without options, it will return an image. But when I use it with options as in .decodeStream(inputStream, null, options) it never returns Bitmaps. What I'm trying to do is to downsample a Bitmap before I actually load it to save memory. I've read some good guides, but none using .decodeStream.

• How to edit the XSL for RSS Viewer Webpart

  - by Nagendra

  I am using a blog site as a source for my RSS Feed. As I see the RSS feed, its showing up as the following :: Blog: Posts Test Thursday, March 04, 2010 - Body: With 25 four's and 3 sixers Sachin crosses 200 (147 balls) runs in an single ODI innings. Creates another world record. Watch the final over where he got it double hundred with MSD on the other end. This is what he had to say after getting the MOM (man of the match): I dedicate this knock to all the people of India, who have supported me throughout over the last 20 years. I was timing the ball well, and I felt that anywhere between 340 to 350 was a good target. I thought Karthik, Yusuf and Dhoni supported me well. I thought that a 200 would be possible once I crossed 175 in the 42nd over. I am enjoying my cricket at the moment. There have been a few bad decisions I have made as a batsman, but as long as the passion is there I will carry on. It feels good that I lasted the 50 overs, it was a good test of my fitness and I would like to do this once again. Well!!! Wait for more. Published: 3/4/2010 3:18 PM More... I actually wanted to remove the Body, Published parameters. I just want my XSLT to be able to show only the Description of the blog. No need to have this meta data. Can anyone help me in specifying tthe XSL changes?

• Grails Mail port configuration

  - by bsreekanth

  Hello, I am trying to send mail through grails mail plugin. I configured according to the documentation, and also followed few blog posts (http://blog.lourish.com/2010/04/02/sending-asynchronous-html-email-in-grails-with-activemq-jms-and-gmail/). That post mention that the closure way of declaring the configuration overrides others, but not true. Anyway I tried both approach, but seems like the port is still use the smtp default one. I get the below exception. exception: org.springframework.mail.MailSendException: Mail server connection failed; nested exception is javax.mail.MessagingException: Could not connect to SMTP host: localhost, port: 25; nested exception is: java.net.ConnectException: Connection refused: connect Now, I wrote a small program directly using the java mail library, and I could send the mail with that. The configuration is shown below. tried additional config "mail.smtp.port":"465"", but no change.. used the parameters mentioned in the above blog post, result same grails { mail { host = "smtp.gmail.com" port = "465" username = "[email protected]" password = "mypwd" props = ["mail.smtp.auth":"true", // "mail.smtp.port":"465", "mail.smtp.socketFactory.port":"465", "mail.smtp.socketFactory.class":"javax.net.ssl.SSLSocketFactory", "mail.smtp.socketFactory.fallback":"false"] } } thanks in advance.. Update: It is not port or firewall config, as when I made a grails application from scratch, and tried with the same config, everything works. Also, asked in grails forum http://grails.1312388.n4.nabble.com/grails-mail-mailSender-does-not-have-config-values-td2237704.html#a2237704 . Hope get a lead to try.

• Android Live Wallpaper: waitForCondition(ReallocateCondition)

  - by jstatz

  I've been developing a live wallpaper using GLWallpaperService, and have gotten good results overall. It runs rock-solid in the emulator and looks good. I've dealt with OpenGL many times before so have a solid command of how to do things... unfortunately I'm having a hell of a time getting this to actually be stable on the actual hardware. The basic symption occurs when you slide the physical keyboard on a Motorola Droid in and out a few times. This causes the wallpaper to get destroyed/recreated several times in quick succession -- which would be fine, as I have my assets clearing in onDestroy and reloading in onSurfaceChanged. The problem is after a few iterations of this, (four or five, maybe) the calls to onSurfaceChanged completely stop, and i get an endless string of this printed to the log: 04-02 00:53:18.088: WARN/SharedBufferStack(1032): waitForCondition(ReallocateCondition) timed out (identity=337, status=0). CPU may be pegged. trying again. Is there something I should be implementing here aside from the Android-typical onSurfaceCreated/onSurfaceChanged/onSurfaceDestroyed triumvirate? Browsing through the WallpaperService and WallpaperRenderer classes doesn't pop up anything obvious to me.

• Creating a (ClickOnce) setup for VSTO Outlook Add-in

  - by Ward Werbrouck

  So I created an Outlook Add-in and used the click-once setup to deploy it. The setup runs fine when the user is administrator, but otherwise: no go. Running the setup with "run as..." and logging in as admin works, but than the add-in is installed under the admin, not the current user. The addin doesn't show up in outlook. I tried following this guide: http://blogs.msdn.com/mshneer/archive/2008/04/24/deploying-your-vsto-add-in-to-all-users-part-iii.aspx But I get stuck at part I: http://blogs.msdn.com/mshneer/archive/2007/09/04/deploying-your-vsto-add-in-to-all-users-part-i.aspx I follow the examples and start excel as described: Now start Excel application. Examine the registry keys in HKCU hive e.g. you will find two interesting registry keys that appear under your HKCU hive: HKCU\Software\Microsoft\Office\TestKey registry key containing registry value TestValue You now also have HKCU\Software\Microsoft\Office\12.0\User Settings\TestPropagation registry key with Count value set to 1 But on my machine, the keys are not created...

• using wget against protected site with NTLM

  Trying to mirror a local intranet site and have found previous questions using 'wget'.

• Parsing third-party XML

  - by mare

  What path would you took to parse a large XML file (2MB - 20 MB or more), that does not have a schema (I cannot infer one with XSD.exe because the file structure is odd, check the snippet below)? Options 1) XML Deserialization (but as said, I don't have a schema and XSD tool complains about the file contents), 2) Linq to XML, 3) loading into XmlDocument, 4) Manual parsing with XmlReader & stuff. This is XML file snippet: <?xml version="1.0" encoding="utf-8"?> <xmlData date="29.04.2010 12:09:13"> <Table> <ident>079186</ident> <stock>0</stock> <pricewotax>33.94000000</pricewotax> <discountpercent>0.00000000</discountpercent> </Table> <Table> <ident>079190</ident> <stock>1</stock> <pricewotax>10.50000000</pricewotax> <discountpercent>0.00000000</discountpercent> <pricebyquantity> <Table> <quantity>5</quantity> <pricewotax>10.00000000</pricewotax> <discountpercent>0.00000000</discountpercent> </Table> <Table> <quantity>8</quantity> <pricewotax>9.00000000</pricewotax> <discountpercent>0.00000000</discountpercent> </Table> </pricebyquantity> </Table> </xmlData>

• How to use SSL3 instead of TLS in a particular HttpWebRequest?

  - by Anton Tykhyy

  My application has to talk to different hosts over https, and the default setting of ServicePointManager.SecurityProtocol = TLS served me well up to this day. Now I have some hosts which (as System.Net trace log shows) don't answer the initial TLS handshake message but keep the underlying connection open until it times out, throwing a timeout exception. I tried setting HttpWebRequest's timeout to as much as 5mins, with the same result. Presumably these hosts are waiting for an SSL3 handshake since both IE and Firefox are able to connect to these hosts after a 30-40 seconds' delay. There seems to be some fallback mechanism in .NET which degrades TLS to SSL3, but it doesn't kick in for some reason. FWIW, here's the handshake message my request is sending: 00000000 : 16 03 01 00 57 01 00 00-53 03 01 4C 12 39 B4 F9 : ....W...S..L.9.. 00000010 : A3 2C 3D EE E1 2A 7A 3E-D2 D6 0D 2E A9 A8 6C 03 : .,=..*z>......l. 00000020 : E7 8F A3 43 0A 73 9C CE-D7 EE CF 00 00 18 00 2F : ...C.s........./ 00000030 : 00 35 00 05 00 0A C0 09-C0 0A C0 13 C0 14 00 32 : .5.............2 00000040 : 00 38 00 13 00 04 01 00-00 12 00 0A 00 08 00 06 : .8.............. 00000050 : 00 17 00 18 00 19 00 0B-00 02 01 00 : ............ Is there a way to use SSL3 instead of TLS in a particular HttpWebRequest, or force a fallback? It seems that ServicePointManager's setting is global, and I'd really hate to have to degrade the security protocol setting to SSL3 for the whole application.

• toggling proximity sensor on iPhone loses an event

  - by slugolicious

  I'm using setProximitySensingEnabled and implemented proximityStateChanged in my UIApplication subclass. It looks like if sensing is toggled, that the first "off" event is being lost. My UIApplication class is pretty basic... -(void)proximityStateChanged:(BOOL)state { NSLog(state ? @"ON" : @"OFF"); } In my application delegate, I have a UISwitch that enables/disables the proximity sensor. -(IBAction)toggleProxy:(id)sender { [UIApplication sharedApplication].proximitySensingEnabled = prox.on; } "prox" is my UISwitch. The test works fine when it first starts. I tap the switch to turn it on and then put my hand over the sensor for a second then move it away and get: 2009-03-11 12:43:00.465 Proximity[324:20b] ON 2009-03-11 12:43:02.514 Proximity[324:20b] OFF 2009-03-11 12:43:04.046 Proximity[324:20b] ON 2009-03-11 12:43:05.621 Proximity[324:20b] OFF I then tap the switch to turn it off then tap again to turn it on. Now I get: 2009-03-11 12:43:12.005 Proximity[324:20b] ON 2009-03-11 12:43:14.789 Proximity[324:20b] ON 2009-03-11 12:43:16.467 Proximity[324:20b] OFF 2009-03-11 12:43:17.516 Proximity[324:20b] ON 2009-03-11 12:43:19.077 Proximity[324:20b] OFF Notice I get two ON's before an OFF. The OFF is lost somewhere. I can't replicate this behavior using Google's mobile app so I'm wondering if they're resetting something in between proximity enabling. They don't have the proximity sensor on all the time because if you cover the sensor, the screen doesn't go blank. You have to tilt the phone up and angle it back (to simulate the position it would be in at your ear) and then covering the sensor works. Anyone else playing with the sensor? In my particular app, I'm recording a voice message and when you move the phone away from your ear, I want to pause the recording (when I get an OFF). The first time I move the phone away from my ear, the recording is not paused. However, if I put it to my ear and move it away again, it is paused.

• Django select distinct sum

  - by yoshi

  I have the following (greatly simplified) table structure: Order: order_number = CharField order_invoice_number = CharField order_invoice_value = CharField An invoice number can be identical on more than one order (order O1 has invoice number I1, order O2 has invoice number I1, etc.). All the orders with the same invoice number have the same invoice value. For example: Order no. Invoice no. Value O1 I1 200 O2 I1 200 O3 I1 200 04 I2 50 05 I2 100 What I am trying to do is do a sum over all the invoice values, but don't add the invoices with the same number more than once. The sum for the above items would be: 200+50+100. I tried doing this using s = orders.values('order_invoice_id').annotate(total=Sum('order_invoice_value')).order_by() and s = orders.values('order_invoice_id').order_by().annotate(total=Sum('order_invoice_value')) but I didn't get the desired result. I tried a few different solutions from similar questions around here but I couldn't get the desired result. I can't figure out what I'm doing wrong and what I actually should do to get a sum that uses each invoice value just once.

If both of them happen at the same time, sort by C1.so in 1&3 it should fetch 3. 3 ahmad 2.3.2010 14:09:59 1 9 19 4 Jim 23.3.2010 16:35:14 4 5 99 I have got a new problem in this. If i filter the records based on conditions the last record is missing. I tried many ways but still it is failing. Here update_log is my table. SELECT * FROM update_log t1 WHERE (t1.c3) = ( SELECT MAX(t2.c3) FROM update_log t2 WHERE DATEDIFF(dd,t2.c3, t1.c3) = 0 ) and t1.c3 > '02.03.2010' and t1.modified_at <= '22.03.2010' ORDER BY t1.c3 ASC. But i am not able to retrieve the record 4 Jim 23.3.2010 16:35:14 4 5 99 I dont know this query results in only 3 ahmad 2.3.2010 14:09:59 1 9 19 The format of the column c3 is datetime. I am pumping the data into the column as using $date = date("d.m.Y H:i",time()); -- simple date fetch of today. Another query that i tried for the same purpose. select * from (select convert(varchar(10), c3,104) as date, max(c3) as max_date, max(c1) as Nr from update_log group by convert(varchar(10), c3,104)) as t2 inner join update_log as t1 on (t2.max_date = t1.c3 and convert(varchar(10), c3,104) = date and t1.[c1]= Nr) WHERE t1.c3 >= '02.03.2010' and t1.c3 <= '16.04.2010' . I even tried this way..the same error last record is not coming..

• Can't connect to local MySQL server through socket

  - by Martin

  I was trying to tune the performance of a running mysql-server by running this command: mysqld_safe --key_buffer_size=64M --table_cache=256 --sort_buffer_size=4M --read_buffer_size=1M & After this i'm unable to connect mysql from the server where mysql is running. I get this error: ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (111) However, luckily i can still connect to mysql remotely. So all my webservers still have access to mysql and are running without any problems. Because of this though i don't want to try to restart the mysql server since that will probably fuck everything up. Now i know that mysqld_safe is starting the mysql-server, and since the mysql server was already running i guess it's some kind of problem with two mysql servers running and listening to the same port. Is there some way to solve this problem without restarting the initial mysql server? UPDATE: This is what ps xa | grep "mysql" says: 11672 ? S 0:00 /bin/sh /usr/bin/mysqld_safe 11780 ? Sl 175:04 /usr/sbin/mysqld --basedir=/usr --datadir=/var/lib/mysql --user=mysql --pid-file=/var/run/mysqld/mysqld.pid --socket=/var/run/mysqld/mysqld.sock --port=3306 11781 ?

• How yo play rington/alarm sound in Android

  - by Federico

  I have been looking everywhere how to play a $#@&! rington/alarm sound in android. I press a button and I want to play a rington/alarm sound. I could not find a easy, strsight forward sample... YES! I already looked at Alarm clock source code... but it is not straight forward and I cannot compile it neither. I cannot make this work: Uri alert = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_ALARM); mMediaPlayer = new MediaPlayer(); mMediaPlayer.setDataSource(this, alert); final AudioManager audioManager = (AudioManager)getSystemService(Context.AUDIO_SERVICE); if (audioManager.getStreamVolume(AudioManager.STREAM_ALARM) != 0) { player.setAudioStreamType(AudioManager.STREAM_ALARM); player.setLooping(true); player.prepare(); player.start(); } I get this error 04-11 17:15:27.638: ERROR/MediaPlayerService(30): Couldn't open fd for content://settings/system/ringtone So.. please if somebody knows how to play a default rington/alarm let me know. I prefer not to upload any file. Just play a default rington. Thanks, Federico

• Dojo DnD: how to access newly copied node on onDndDrop event?

  - by toshinao

  Hi. I am working on code like the following. 01: var c1 = new dojo.dnd.Source('container1', {copyOnly:true}); // container1 is a div 02: var c2 = new dojo.dnd.Source('container2'); // container2 is a div 03: var list = []; 04: for (var i = 0; i < 3; i++) { list.push( dojo.create('div') ); } 05: c1.insertNodes(false, list); 06: 07: function checkDndCopy(nodes, target){ 08: dojo.forEach(nodes, function(node){ alert(node.id); } ); 09: } 10: dojo.subscribe("/dnd/drop", function(){ 11: var mgr = dojo.dnd.manager(); 12: checkDndCopy(mgr.nodes, mgr.target); 13: }); The nodes inserted to the c1 at line 05 have id of "dojoUnique1, donoUnique2, dojoUnique3". On a event of drag and drop a node from c1 to c2, a onDndDrop event is fired and the subscribe method defined in line10-13 is invoked. I expected that newly copied node appears in the nodes (for example) at line 08. But this is not true. When dojoUnique1 is target of drag and drop, nodes at line 08 contains only dojoUnique1. I want to modify some attributes of newly copied nodes on the event of onDndDrop. Please let me know how such a thing is realized.

• Wrong Ruby Float and BigDecimal subtraction result

  - by SamChandra

  I am running: [~/ruby/rails/sas]$ ruby --version ruby 1.8.7 (2009-06-08 patchlevel 173) [universal-darwin10.0] on Mac Snow Leopard 10.6.3 Can anyone help to explain why the Float and BigDecimal subtraction can be this wrong. [~/ruby/rails/sas]$ console Loading development environment (Rails 2.1.1) >> num = 30.0 => 30.0 >> num.class => Float >> ex = 28.04.to_d => #<BigDecimal:105367e40,'0.284E2',8(8)> >> ex.class => BigDecimal >> num - ex => 1.6 >> _.class => Float >> I was hoping that the result should be 1.96, I know that perhaps doing an arithmetic operation using 2 different data types are not recommended, but this behavior is so strange. It seems to be wise that from now on, I have to check the variables data type before doing any arithmetic operation. Hopefully somebody can give me an insight on what was happening.

• How do I debug a HTTP 502 error?

  - by Bialecki

  I have a Python Tornado server sitting behind a nginx frontend. Every now and then, but not every time, I get a 502 error. I look in the nginx access log and I see this: 127.0.0.1 - - [02/Jun/2010:18:04:02 -0400] "POST /a/question/updates HTTP/1.1" 502 173 "http://localhost/tagged/python" "Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9.2.3) Gecko/20100401 Firefox/3.6.3" and in the error log: 2010/06/02 18:04:02 [error] 14033#0: *1700 connect() failed (111: Connection refused) while connecting to upstream, client: 127.0.0.1, server: _, request: "POST /a/question/updates HTTP/1.1", upstream: "http://127.0.0.1:8888/a/question/updates", host: "localhost", referrer: "http://localhost/tagged/python" I don't think any errors show up in the Tornado log. How would you go about debugging this? Is there something I can put in the Tornado or nginx configuration to help debug this? EDIT: In addition, I get a fair number of 504, gateway timeout errors. Is it possible that the Tornado instance is just busy or something?

• Issues with Rails, Amazon S3, and protected URLs

  - by Shpigford

  So I followed this little tutorial about protecting downloads of files that are uploaded to Amazon S3 with Paperclip. When I've developed locally, it's worked fine, but since pushing the exact same code to a production server...I now get this error from Amazon when I try to access the files: <Error> <Code>InvalidArgument</Code> <Message>Either the Signature query string parameter or the Authorization header should be specified, not both</Message> <ArgumentValue>Basic dGVjaHVrdWxlbGU6ZWxlbHVrdWhjZXQ=</ArgumentValue> <ArgumentName>Authorization</ArgumentName> <RequestId>F6E455857C54F95A</RequestId> <HostId>X4QA2pw9wpHtJtJ2T8qxCyINjq4PLHQVF4VrlYjpX7Ayh694BgQprh5p8H7NRCAt</HostId> </Error> Example URL: http://s3.amazonaws.com/media.example.com/assets/videos/1/original.mov?AWSAccessKeyId=MY_ACCESS_KEY&Expires=1271972624&Signature=7wWH2WYHPO0o9szwPJbimUMqAig%3D That URL is generated using AWS::S3::S3Object.url_for using the aws-s3 gem. So...not even sure where to start. The fact that it works fine when the app is running locally but not when in production really doesn't make sense. The production server is running Ubuntu 8.04.4 LTS (Hardy).

  - by mamcx

  I download the Application Verifier 4.0 to test my App for check if could have problems on Vista/7. I run from Delphi 2010 debugger, and stop in CPU view. Obviously, I don't understand anything about assembler!. So, I try running directly from the windows explorer, and the App die. (In fact, I don't understand well what exactly will do App Verifier: I expect some kind of friendly message).
