• PDF form submission

  - by Jeff

  I have a PDF form (made in Acrobat) that has button to submit via HTTP. What I want to do it have a PHP script that will take the PDF form and e-mail it to me via attachment. What I don't want: --PDF Submit via e-mail button. This requires webmail users to save the pdf and attach it, and is just too confusing for most users. I want one-click and done. --Submit via mailto:[email protected]. Does the same thing as above. If there's a pdf on the server, I know how to use PHP's mail() function to e-mail it to someone. What I don't know how to do is process the PDF once someone hits Submit within the PDF. Does that make sense? Thanks, Jeff

• How to "chain" modal dialogs in YUI 2 ?

  - by giulio

  I have a modal dialog box presented in Yahoo UI. The user selects a value from dialog "A", and then I want to present another modal dialog box to collect some more data in dialog "B". I have been using the YAHOO.widget.Dialog successfully. The problem seems to be that you can't initiate dialog window "B" from the handler function of dialog "A". So, how can you programmatically launch a second dialog window after the user hits the "OK" button on the first ? (I had tried to create an additional Listener for a field that is updated in dialog "A" to trigger dialog "B" but this doesn't work either.) Thanks..

• Weak linking on iPhone refuses to work

  - by Jonathan Grynspan

  I've got an iPhone app that's mainly targetting 3.0, but which takes advantage of newer APIs when they're available. Code goes something like this: if (UIApplicationDidEnterBackgroundNotification != NULL) [nc addObserver: self selector: @selector(irrelelvantCallbackName:) name: UIApplicationDidEnterBackgroundNotification object: nil]; Now, according to everything Apple's ever said, if the relevant APIs are weakly linked, that will work fine because the dynamic linker will evaluate UIApplicationDidEnterBackgroundNotification to NULL. Except that it doesn't. The application compiles, but as soon as it hits "if (UIApplicationDidEnterBackgroundNotification != NULL)" it crashes with EXC_BAD_ACCESS. Is this simply a matter of a compiler flag I need to set? Or am I going about this the wrong way?

• StreamReader ReadToEnd() after HttpWebRequest EndGetResponse() - most scalable?

  - by frankadelic

  I am calling a RESTful web service in the back-end of some ASP.NET pages. I am using ASP.NET asynchronous pages, so under the hood I am using the methods: HttpWebRequest BeginGetResponse() and HttpWebRequest EndGetResponse() The response string in my case is always a JSON string. I use the following code to read the entire string: using (StreamReader sr = new StreamReader(myHttpWebResponse.GetResponseStream())) { myObject.JSONData = sr.ReadToEnd(); } Is this method OK in terms of scalability? I have seen other code samples that instead retrieve the response data in blocks using Read(). My primary goal is scalability, so this back-end call can be made across many concurrent page hits. Thanks, Frank

• linq Except and custom IEqualityComparer

  - by Joe

  I'm trying to implement a custom comparer on two lists of strings and use the .Except() linq method to get those that aren't one one of the lists. The reason I'm doing a custom comparer is because I need to do a "fuzzy" compare, i.e. one string on one list could be embedded inside a string on the other list. I've made the following comparer ` public class ItemFuzzyMatchComparer : IEqualityComparer { bool IEqualityComparer<string>.Equals(string x, string y) { return (x.Contains(y) || y.Contains(x)); } int IEqualityComparer<string>.GetHashCode(string obj) { if (Object.ReferenceEquals(obj, null)) return 0; return obj.GetHashCode(); } } ` When I debug, the only breakpoint that hits is in the GetHashCode() method. The Equals() never gets touched. Any ideas?

• how to bind to the results of a query in WPF

  - by randyc

  I have a query that hits a service and returns the results back to me as an indexed collection static void QueryActivities() { QueryClient qc = new QueryClient("BasicHttpBinding_IQuery"); QueryFilter filter = new QueryFilter(); filter.CallForService = false; var result = qc.GetFilteredActivityIndex(filter); result.Clone(); //inserted this just to test return in debug mode } WHen this is executed I get a return of 5 records ( actually five rows of data with multiple values per each row. id, type, date, address etc). I would like to bind this return to a gridview within a WPF application. Is there a way to refernce and bind to result variable or do I need to create a new collection and then add the return of result to the new collection? thank you

• Mercurial Pull Error

  - by Tyler

  I am new to the dvcs world. My company uses perforce and I'm not a fan so I thought I'd try to use mercurial as a front end. I set it up on a windows machine with TortiseHG, enabled the Perfarce extension, did a small checkout (limiting the target revision) and pulled for the rest. This seemed to be more robust than clone alone. This seems to be working fairly well as I've been able to get up to change 8700 or so. My problem is with an error in the perforce repo. During the hg pull command it hits an error abort: file path/to/file.pl missing in p4 workspace and rolls back the transaction. Is there anyway to bypass or skip that file and force it to continue since this is not a file I care about.

• How do I obtain a new stateful session bean in a servlet thread?

  - by FarmBoy

  I'm experimenting with EJB3 I would like to inject a stateful session bean into a servlet, so that each user that hits the servlet would obtain a new bean. Obviously, I can't let the bean be an instance variable for the servlet, as that will be shared. And apparantly injecting local variables isn't allowed. I can use the new operator to create a bean, but that doesn't seem the right approach. Is there a right way to do this? It seems like what I'm trying to do is fairly straightforward, after all, we would want each new customer to find an empty shopping cart.

• How does MTOM work + sample code

  - by zengr

  I am trying to make a very simple web-service which does the following: The client hits the web service requesting a file. The web service's service class queries a hashtable which has the key (search query) and the value as the base64encoded value of a file (say a pdf) Now,I need to use MTOM to return the base64encoded value stored in the hashtable to the client. It's upto the client to decode it and convert it to pdf. So, here are my questions: I understand we encode files to base64 for transmission via web service, but where and how does MTOM come into the picture there? Can some one provide me a simple method which uses MTOM and sends the data back. Do we need to specify something in the WSDL too? or a simple String return type would suffice? Why/Why not? Thanks I have seen this code. It uses a lot of annotations, I just need a simple java code using MTOM. New to J2EE HERE :)

• capture flash key event "escape"

  - by P..

  I have a flash site that users can view full Screen video. the trouble is, I am making only the video player full screen (hiding the rest of the site behind it). my "toggle full screen" button works in that it reduces the video player back to normal size when the user toggles out of full screen back. but when the user hits the escape key, my flash script doesn't know that the video player should be reduced in size. it seems there's no way to capture the ESCAPE key as a key event. any ideas?

• SqlServer2008 - Can I Alter a Scalar Function while it is referenced in many places

  - by Casey C.

  We have a scalar function that returns a DateTime. It performs a couple of quick table selects to get its return value. This function is already in use throughout the database - in default constraints, stored procs, etc. I would like to change the implementation of the function (to remove the table hits and make it more efficient) but apparently I can't do that while it is referenced by other objects in the database. Will I actually need to update every object in the database that references it to remove the reference, update the function and then update all those objects to restore the reference to the function? Thanks for any insight you can give.

• Removing http301 redirect from client's cache

  - by ChessWhiz

  Hi, I have a server/client architecture where the client hits the ASP.NET server's service at a certain host name, IP address, and port. Without thinking, I logged on to the server and set up permanent HTTP301 redirection through IIS from that service to another URL that the machine handles via IIS (same IP and port), mistakenly thinking it was another site that is hosted there. When the client hit the server at the old host name, it cached the permanent redirect. Now, even though I have removed the redirection, the client no longer uses the old address. How can I clear the client's cache so that it no longer stores the redirect? I have read about how permanent HTTP301 can be, but in this case, it should be possible to reset a single client's knowledge of the incorrectly-learned host name. Any ideas?

• Tuning OS X Virtual Memory

  I've noticed some really odd results form vm_stat on OSX 10.6. According to this, its barely hitting the cache.

• Displaying desired properties from search results with grails compass

  - by ombud

  Hi, I've been stumped with the problem of displaying a selected set of properties returned as a result via a Compass query in grails. I have 300 columns in my domain class and what I'd like to do is to return ONLY THOSE values I specify (around 10 - 15 properties/fields/columns). All the 300 columns have been indexed, btw. I know I can do this using Lucene by cycling through returned hits and selectively calling a=getField(column_name), et c. My qiuestion is, how do I do the same thing using thee Compass Grails plugin ? Any help will gratefully be appreciated. Thanks in anticipation, Ombud

• Connect rails application to MsSQL 2005 from Windows

  - by Enrico Carlesso

  Hi guys. I (sadly) have to deploy a rails application on Windows XP which has to connect to Microsoft SQL Server 2005. Surfing in the web there are a lot of hits for connect from Linux to MsSQL, but cannot find out how to do it from Windows. Basically I followed these steps: Install dbi gem Install activerecord-sql-server-adapter gem My database.yml now looks like this: development: adapter: sqlserver mode: odbc dsn: test_dj host: HOSTNAME\SQLEXPRESS database: test_dj username: guest password: guest But I'm unable to connect it. When I run rake db:migrate I get IM002 (0) [Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified I'm not a Windows user, so cannot understand really well the meaning of dsn element or so. Does someone have an idea how to solve this? Thanks in advance

• JPA Cascading Delete: Setting child FK to NULL on a NOT NULL column

  - by JBristow

  I have two tables: t_promo_program and t_promo_program_param. They are represented by the following JPA entities: @Entity @Table(name = "t_promo_program") public class PromoProgram { @Id @Column(name = "promo_program_id") private Long id; @OneToMany(cascade = {CascadeType.REMOVE}) @JoinColumn(name = "promo_program_id") private List<PromoProgramParam> params; } @Entity @Table(name = "t_promo_program_param") public class PromoProgramParam { @Id @Column(name = "promo_program_param_id") private Long id; //@NotNull // This is a Hibernate annotation so that my test db gets created with the NOT NULL attribute, I'm not married to this annotation. @ManyToOne @JoinColumn(name = "PROMO_PROGRAM_ID", referencedColumnName = "promo_program_id") private PromoProgram promoProgram; } When I delete a PromoProgram, Hibernate hits my database with: update T_PROMO_PROGRAM_PARAM set promo_program_id=null where promo_program_id=? delete from t_promo_program where promo_program_id=? and last_change=? I'm at a loss for where to start looking for the source of the problem.

• Null object that is not null

  - by Guillaume

  Hello, I use 2 threads to act like a produce/consumer using double queue (http://www.codeproject.com/KB/threads/DoubleQueue.aspx). Sometimes in my 2nd thread, I get an object that is NULL but it should not be as I filled it in the first thread. I tried this: if(myObject.Data == null) { Console.WriteLine("Null Object") // <-- Breakpoint here } When I my break point hits, I can watch myObject.Data and indeed it's NULL, but when I hit F10 and then go to the next line (which is } ) myObject.Data is not NULL. I also added a lock on myObject before if .... to be sure that no one whould use this object. How is that possible and what can I do ?

• RockBand-like voice app for PC/OSX / Real time pitch display software

  - by Sai Emrys

  I played Rock Band 2 for the first time a little while ago (at Notacon). One thing I enjoyed about it was getting real-time feedback about my singing. I think it'd be neat to have something like that to run alongside my usual music, so that I can sing to random stuff in my music collection and know when I'm hitting the notes. Is there something like this for PC - ideally for OSX, and ideally that can just operate on arbitrary songs? I don't really care if it's game-like (though that's neat too); I just want it for the singing feedback. And I have no need for pitch correction - ideally what I'd see is just the pitches of the notes in the music and (on the same scale, differently displayed) of the live microphone. I tried to STFW but got no salient hits. :-/ Thanks!

• Lucene search taking TOOO long.

  - by Josh Handel

  I;m using Lucene.net (2.9.2.2) on a (currently) 70Gig index.. I can do a fairly complicated search and get all the document IDs back in 1 ~ 2 seconds.. But to actually load up all the hits (about 700 thousand in my test queries) takes 5+ minutes. We aren't using lucene for UI, this is a datastore between processes where we have hundreds of millions of pre-cached data elements, and the part I am working on exports a few specific fields from each found document. (ergo, pagination doesn't make since as this is an export between processes). My question is what is the best way to get all of the documents in a search result? currently I am using a custom collector that does a get on the document (with a MapFieldSelector) as its collecting.. I've also tried iterating through the list after the collector has finished.. but that was even worse. I'm open to ideas :-). Thanks in advance.

• Best way to optimize queries like this in Django

  - by chris

  I am trying to lower the amount of queries that my django app is using, but I am a little confused on how to do it. I would like to get a query set with one hit to the database and then filter items from that set. I have tried a couple of things, but I always get queries for each set. let's say I want to get all names from my DB, but also separate out the people just named Ted. Both the names and the ted set will be used in the template. This will give me two sets, one with all names and one with Ted.. but also hits the database twice: namelist = People.objects.all() tedList = namelist.filter(name='ted') Is there a way to filter the first set without hitting the data base again?

• Creating a notification system using a firefox extension

  - by user303052

  I am creating a firefox extension that should give a notification when the user hits specific sites. I do not want the same kind of notification that firefox gives for pop-ups. I don't want the user to have to go through the hassle of clicking the X in order to close the notification. Instead, I would like it to look like what happens when a normal firefox download is completed - a notification comes up, and automatically goes after a few seconds. On a mac, it looks like a growl notification, and I love the way it looks. Is there an easy way to implement this feature? Thanks

• Millions of anonymous ASP.Net profiles!?

  - by Mantorok

  Hi all, some advice needed! Our website receives approximately 50,000 hits a day, and we use anonymous ASP.Net membership profiles/users, this is resulting in millions (4.5m currently) of "active" profiles and the database is 'crawling', we have a nightly task that cleans up all the inactive ones. There is no way that we have 4.5m unique visitors (our county population is only 1/2 million), could this be caused by crawlers and spiders? Also, if we have to live with this huge number of profiles is there anyway of optimising the DB? Thanks Kev

• 2D Gaming - How to reflect a ball off the bat?

  - by sid

  Hi there I am pretty new to XNA & game dev and am stuck at ball reflection. My ball is reflecting once it hits the bat, but only in one angle, no matter which angle the bat is at. Here's the code: if (BallRect.Intersects(BatRect)) { Vector2 NormBallVelocity = Ball.velocity; NormBallVelocity.Normalize(); NormBallVelocity = Vector2.Reflect(Ball.velocity, NormBallVelocity); Ball.velocity = NormBallVelocity; } The ball is retracting its way back. How do I make it look like the ball is reflecting off the bat? I have seen other posts but they are on 3D front I am too new to translate it to 2D terms... Thanks Sid
