• How to rename the original file before sending it to user

  - by Manish Jangir

  Actually I have some download link on my website something like "http://www.example.com/somesong.mp3". Now when user click on this link they get somesong.mp3 but I want to change it before they download. I found many scripts that made it possible but didn't get exact right script. Because I want that when the user clicks on download link the file downloading should be started just after the click with the new file name as I want to use. But in all the scripts which I downloaded, first the php processing starts for a few minute (I think it depends on the file size) and then rename it. Is there a way to direct force the file in header with new file name. Thanks.

• How to specify a password on the command line of an SSIS package run

  - by Vaccano

  I am having an issue where I need to be able to specify the password when I run my packages. This article http://support.microsoft.com/kb/918760 says: Method 3: Set the SSIS Package ProtectionLevel property to EncryptSensitiveWithPassword Change the SSIS Package ProtectionLevel property to EncryptSensitiveWithPassword. This setting uses a password for encryption. You can then modify the SQL Server Agent job step command line to include this password. That all sounds well and good. But where and how to you specify the password? Here is an example of my current command line: /FILE "C:\Program Files\Microsoft SQL Server\100\DTS\Packages \MainSSISPackage.dtsx" /CONFIGFILE "C:\Program Files \Microsoft SQL Server\100\DTS\Packages\DataConfig.dtsConfig" /CHECKPOINTING OFF /REPORTING E

• Use of WebDAV to access OWA (exchange 2003) mails with Basic authentication and SSL

  - by Mayuresh

  I have got a working C# code for accessing OWA mails using WebDAV against a FBA enabled exchange 2003 (http://support.microsoft.com/kb/891748/en-us/) But my client's OWA (exchange 2003) has Basic authentication and SSL (i-e when I try to access the web mail link through browser I get a grey login box instead of a web page I can log into the mail box once I enter the correct details) But my same fails with a 401 error against this mailbox. I got the simple request working for the Basic authentication using – String usernamePassword = strUserName + ":" + strPassword; WebReq.Headers.Add("Authorization", "Basic " + Convert.ToBase64String(new ASCIIEncoding().GetBytes(usernamePassword))); But the subsequent WebDAV SEARCH request fails with 404 (resource not found) error. Can we use WebDAV against an exchange 2k3 with SSL and Basic authentication?

• Windsor + NHibernate + ISession + MVC

  - by dbones

  Hi I am trying to get Windsor to give me an instance ISession for each request, which should be injected into all the repositories Here is my container setup container.AddFacility<FactorySupportFacility>().Register( Component.For<ISessionFactory>().Instance(NHibernateHelper.GetSessionFactory()).LifeStyle.Singleton, Component.For<ISession>().LifeStyle.Transient .UsingFactoryMethod(kernel => kernel.Resolve<ISessionFactory>().OpenSession()) ); //add to the container container.Register( Component.For<IActionInvoker>().ImplementedBy<WindsorActionInvoker>(), Component.For(typeof(IRepository<>)).ImplementedBy(typeof(NHibernateRepository<>)) ); Its based upon a StructureMap post here http://www.kevinwilliampang.com/2010/04/06/setting-up-asp-net-mvc-with-fluent-nhibernate-and-structuremap/ however, when this is run, a new Session is created for every object it is injected too. what am I missing? thanks in advanced (FYI the NHibernateHelper, sets up the config for Nhib)

• Howto plot two cumulative frequency graph together

  - by neversaint

  I have data that looks like this: #val Freq1 Freq2 0.000 178 202 0.001 4611 5300 0.002 99 112 0.003 26 30 0.004 17 20 0.005 15 20 0.006 11 14 0.007 11 13 0.008 13 13 ...many more lines.. Full data can be found here: http://dpaste.com/173536/plain/ What I intend to do is to have a cumulative graph with "val" as x-axis with "Freq1" & "Freq2" as y-axis, plot together in 1 graph. I have this code. But it creates two plots instead of 1. dat <- read.table("stat.txt",header=F); val<-dat$V1 freq1<-dat$V2 freq2<-dat$V3 valf1<-rep(val,freq1) valf2<-rep(val,freq2) valfreq1table<- table(valf1) valfreq2table<- table(valf2) cumfreq1=c(0,cumsum(valfreq1table)) cumfreq2=c(0,cumsum(valfreq2table)) plot(cumfreq1, ylab="CumFreq",xlab="Loglik Ratio") lines(cumfreq1) plot(cumfreq2, ylab="CumFreq",xlab="Loglik Ratio") lines(cumfreq2) What's the right way to approach this?

• FileNotFoundException when cropping a photo

  - by James G

  I'm trying to crop a photo to use in a Live Wallpaper but I'm getting a FileNotFoundException when the crop activity tries to save my new cropped image. This is the code I'm using: File file = new File(getFilesDir(), "wallpaper.jpg"); Intent intent = new Intent("com.android.camera.action.CROP"); intent.setData(uri); DisplayMetrics metrics = new DisplayMetrics(); getWindowManager().getDefaultDisplay().getMetrics(metrics); intent.putExtra("outputX", metrics.widthPixels * 2); intent.putExtra("outputY", metrics.heightPixels); intent.putExtra("aspectX", metrics.widthPixels * 2); intent.putExtra("aspectY", metrics.heightPixels); intent.putExtra("scale", true); intent.putExtra("noFaceDetection", true); intent.putExtra("output", Uri.parse("file:/" + file.getAbsolutePath())); startActivityForResult(intent, REQUEST_CROP_IMAGE); The wallpaper.jpg file seems to exist on DDMS file explorer so I'm not sure what I'm doing wrong. Any advice is greatly appreciated.

• Why do Java and C# not have implicit conversions to boolean?

  - by Shaun

  Since I started Java it's been very aggravating for me that it doesn't support implicit conversions from numeric types to booleans, so you can't do things like: if (flags & 0x80) { ... } instead you have to go through this lunacy: if ((flags & 0x80) != 0) { ... } It's the same with null and objects. Every other C-like language I know including JavaScript allows it, so I thought Java was just moronic, but I've just discovered that C# is the same (at least for numbers, don't know about null/objects): http://msdn.microsoft.com/en-us/library/c8f5xwh7(VS.71).aspx Microsoft changed it on purpose from C++, so why? Clearly I'm missing something. Why change (what I thought was) the most natural thing in the world to make it longer to type? What on Earth is wrong with it?

• Android: Alignment of four squares

  - by metter

  Hello There I am trying to align four equally sized squares on an Android Screen & I have now tried what feels like a million different approaches, yet none of them seem to work :(. What I've got at the moment is the following: <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/MasterLayout" android:layout_width="wrap_content" android:layout_height="fill_parent" android:background="#FFFFFF" <TableRow android:layout_weight="1" android:background="#BBBBBB" android:padding="0dip"> <TableRow android:layout_weight="1" android:padding="0dip"> This basically does the job. However, every one of those four Images has a huge padding above and under it. How do I get rid of that? Or do I need to use a different Layout type alltogether? To help illustrate my problem, here's a picture. On the left is what I got, on the right is what I need. Image Thank you very much! Cheers, Markus!

• Bash script to (more or less) reliably check if the internet is up

  - by João Portela

  I need a bash script to put in a cron job that every minute checks if the internet is up. This is how I did it: #! /bin/sh host1=google.com host2=wikipedia.org curr_date=`date +"%Y%m%d%H%M"` echo -n "${curr_date};" ((ping -w5 -c3 $host1 || ping -w5 -c3 $host2) > /dev/null 2>&1) && echo "up" || (echo "down" && exit 1) How would you do it? Which hosts would you ping? Thanks in advance.

• [solved] What's wrong with this jQuery example?

  The following jQuery example should put some text into the div, but it doesn't.

• Are volatile data members trivially copyable?

  - by Lightness Races in Orbit

  Whilst writing this answer I realised that I'm not as confident about my conclusions as I usually would ensure before hitting Post Your Answer. I can find a couple of reasonably convincing citations for the argument that the trivial-copyability of volatile data members is either implementation defined or flat-out false: https://groups.google.com/forum/?fromgroups=#!topic/comp.std.c++/5cWxmw71ktI http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48118 http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2010/n3159.html#496 But I haven't been able to back this up in the standard1 itself. Particularly "worrying" is that there's no sign of the proposed wording change from that n3159 issues list in the actual standard's final wording. So, what gives? Are volatile data members trivially copyable, or not? 1   C++11

  - by M.ES

  I've got the following layout with one ImageView and 2 TextView, I would like them all to have the same height. However, the ImageView is always taking more than half of the screen. Any help is highly apreciated. Here is the layout: <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent" android:background="#FFFFFF" android:orientation="vertical" > <ImageView android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_weight="0.4" android:src="@drawable/sprint" /> <TextView android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_weight="0.3" android:background="#555555" android:text="@string/hello" /> <TextView android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_weight="0.3" android:text="@string/hello" /> </LinearLayout>

• "Easiest" way to track unique visitors to a page, in real time?

  - by Cooper

  I need to record in "real time" (perhaps no more than 5 minute delay?) how many unique visitors a given page on my website has had in a given time period. I seek an "easy" way to do this. Preferably the results would be available via a database query. Two things I've tried that failed (so far): Google Analytics: Does the tracking/reporting, but not in real time - results are delayed by hours. Mint Analytics ( http://www.haveamint.com/ ): Tracks in real time, but seems to aggregate data in a way that prevents reporting of unique visitors to a single page over an arbitrary time frame. So, does anyone know how to make Mint Analytics do what I want, or can anyone recommend an analytics package or programmed approach that will do what I need?

• How to create a repository workspace which contains all of the components of a stream using scm tool?

  - by user470184

  I'm attempting to automate the updating of a file in a stream using 'scm' Here is how I think it should work : Login to the repository as current user (me) Create a new repository workspace which contains all of the components of a given Stream Load the components of the newly created workspace Update the file I'm on point 2. Reading about the 'create workspace' doc on http://pic.dhe.ibm.com/infocenter/rtc/v1r0m0/index.jsp?topic=%2Fcom.ibm.team.scm.doc%2Ftopics%2Fc_scm_cli.html it does'nt mention how to create a new workspace which contains all of the components of a given stream. So how can I implement point 2 ? Any comments on my methodolgy if can be improved upon also appreciated.

• CSS not displayed depending on page

  - by Kanjiroushi

  I have a friend that has a really strange issue with my website. When he clicks on http://www.copeo.fr/ the page displays fine but when he clicks on a link like www.copeo.fr/user/ the CSS is not applied even after a refresh. The raw html does display. I asked him to display the CSS that is hosted on amazon S3 hcopeoressources.s3.amazonaws.com/style/futurvert/style.css and it displays fine. The code validates on W3C validator so does the CSS. I am lost what could be the origin of the issue. Could it be its enterprise cache? configuration of IE7 on his machine? If it happens to someone else who could explain the issue to me, I am all hears. Thanks

• jquery ui dialog - live not working?

  - by ile

  I'm using this dialog: http://docs.jquery.com/UI/Dialog To open dialog I do it this way: $('a.openModal').live("click", function() { var idArr = $(this).attr('id').split("OpenNote"); var id = idArr[1]; alert($(".modalNote#dialog-modal" + id).html()); $(".modalNote#dialog-modal" + id).dialog('open'); return false; }); This dialog is used to display content of note when title is clicked. When I generated html on pageload, then this works fine, but if I add html dynamically then dialog won't open. It is also not hidden when it's appended to div. Is it possible to open it "on-fly"?

• Persisting non-entity class that extends an entity (jpa) - example?

  - by Michal Minicki

  The JPA tutorial states that one can have a non-entity that extends entity class: Entities may extend both entity and non-entity classes, and non-entity classes may extend entity classes. - http://java.sun.com/javaee/5/docs/tutorial/doc/bnbqa.html Is it possible to persist such structure? I want to do this: @Entity abstract class Test { ... } class FirstConcreteTest extends Test { ... } // Non-ntity class SecondConcreteTest extends Test { ... } // Non-entity Test test = new FirstConcreteTest(); em.persist(test); What I would like it to do is to persist all fields mapped on abstract Test to a common database table for all concrete classes (first and second), leaving all fields of first and second test class unpersisted (these can contain stuff like EJBs, jdbc pools, etc). And a bonus question. Is it possible to persist abstract property too? @Entity abstract class Test { @Column @Access(AccessType.PROPERTY) abstract public String getName(); } class SecondConcreteTest extends Test { public String getName() { return "Second Concrete Test"; } }

• filter lists that are split by easylistsplitter.js?

  - by Jason

  Hi Everyone, At my site - jasondaydesign.com. I'm using easylistsplitter.js. I designed it this way, because I actually wanted a masonry.js style layout but I couldn't find a way to filter divs. So I made the switch to lists, and found a plugin that allowed me to have a masonry style layout. Unfortunately, I have tried several list filters including: filterprojects.js and a netuts tutorial on a filterable portfolio. Unfortunately, both work, but only on the first column. I can't seem to figure out a way to have a filter plugin work on all list items that have been split by easylistsplitter.js Thoughts?
