• Deploying service from development server to iis7 server

  - by MindWorX

  I have a service which works perfectly on the local development server, but once moved to the remote iis7 server, it fails. I've been browsing the service in a browser manually. Here's the steps I've been taking: Open up Service.svc Open up Service.svc?wsdl Open up Service.svc?wsdl0 Open up Service.svc?xsd=xsd0 Step 4. is where it fails. If i browse on the development server it works. If i browse on the iis7 server, I get a connection reset error. Any help appreciated.

• Alternative for PHPlivedocx?

  - by Derek

  Hello, Is there any other free alternatives to PHPliveDocx? I would like to create a Word document based on templates and user inputted data. The template will resides on the server and the client(online or c# windows application) will be used to collect user input. Once data has been collected, server-side script(PHP) will be used to generate a Word document. So far I have only found phplivedocx. However I'm not very comfortable at consuming web services from a server that I have no control over with (am I worrying too much?). I have also thought about using client to do the work (c# windows application, Open Office XML). But I'm not sure that's the right way of doing things. Any guidance/help will be really appreciated! Thanks!

• Extract page from PDF using iText and clojure

  - by KobbyPemson

  I am trying to extract a single page from a pdf with clojure by translating the splitPDF method I found here http://viralpatel.net/blogs/itext-tutorial-merge-split-pdf-files-using-itext-jar/ I keep getting this error IOException Stream Closed java.io.FileOutputStream.writeBytes (:-2) This prevents me from opening the document while the repl is still open. Once I close the repl I'm able to access the document. Why do I get the error? How do I fix it ? How can I make it more clojurey? (import '(com.itextpdf.text Document) '(com.itextpdf.text.pdf PdfReader PdfWriter PdfContentByte PdfImportedPage BaseFont) '(java.io File FileInputStream FileOutputStream InputStream OutputStream)) (defn extract-page [src dest pagenum] (with-open [ d (Document.) os (FileOutputStream. dest)] (let [ srcpdf (->> src FileInputStream. PdfReader.) destpdf (PdfWriter/getInstance d os)] (doto d (.open ) (.newPage )) (.addTemplate (.getDirectContent destpdf) (.getImportedPage destpdf srcpdf pagenum) 0 0))))

• Authenticate sites with different domain names using the Facebook API

  - by Onema

  We have a CMS that supports multiple sites, one of our features allows our users (The site admin) to connect to the site facebook account to allow status updates, create events and upload pictures to FB from with in the CMS. The authentication needs to occur once since each site may have multiple site admins that do not have access to the site FB user name and password. We use iframe and authenticate using $facebook-require_login() which redirects the user to the FB login and authentication pages. All this works just fine but when the user hits "Allow" the authentication will break as it will only redirect to whatever is in the "Post-Authorize Redirect URL" field making the app obsolete for any other domain except the one in the "Post-Authorize Redirect URL" I know other API's authentication methods like in Vimeo and YouTube will allow you to specify a NEXT parameter which is the equivalent of the "Post-Authorize Redirect URL" and it can be set at run time. How can I make this work for multiple domain names? Any hints on this issue will be of great help

• copy or clone a HSSFWorkbook

  - by Fortega

  Hi, Currently I am doing the following in a loop (at least 300 times): - create a HSSFWorkbook from a template file - add some values to specific cells in the workbook - save the workbook as a new excel file The first line takes about 70% of the time (reading excel file). What I would like to do is to take this out of the loop, and read the file only once. In the loop, I would like to copy or clone the template HSSFWorkbook. However, I can't find anything about copying/cloning a HSSFWorkbook. Did some of you do this before? Any tips?

• Recovering the deleted data from Android SD Card ?

  - by Nish

  I am trying to make an Android application which would try to recover deleted content from the SD Card. How feasible it is ? I have following method in mind: 1) Since, the files are not actually deleted, can I access the file system to see files which has been marked to be overwritten. 2) Or will I have do header/footer file carving ? Is it possible from the application layer of android ? I am concerned about files stored on contiguous sectors and not the fragmented once. I want to do a basic file retrieval. Please let me know some resources which I can use to make this application ?

• Graphics.FromHwnd(IntPtr.Zero) returns null, why?

  - by Martin Moser

  I'm currently investigating a problem with a 3rd party component (DevExpress) in my application. My issue is quite similar to this one DevExpress KB article. I get the same exception with more less the same stacktrace. So I used .NET Reflector to find out, what may be null in this scenario, and the only object which is a candiate to be null is Graphics. This is created with Graphics.FromHwnd(IntPtr.Zero). Because I don't have a broad knowledge about GDI, I would like to know if somebody can tell me possible scenarios when this may return null... I tried to reproduce it in a scenario where windows is out of GDI handle's, but then I'm getting a "out of handles" - exception at least once, which is not the case in the issue I'm investigating tia, Martin

• How to write async background workers that work on WPF flowdocument

  - by iBe

  I'm trying to write a background worker that processes a flowdocument. I can't access the properties of flowdocument objects because of the thread verification. I tried to serialize the document and loaded it on the worker thread which actually solved the thread verfication issue. However, once the processing is complete I also need to use things like TextPointer objects. Those objects now point to a objects in the copy not the original. Can anyone suggest the best way to approach such background processing in WPF?

• Gaining information from nodes of tree

  - by jainp

  I am working with the tree data structure and trying to come up with a way to calculate information I can gain from the nodes of the tree. I am wondering if there are any existing techniques which can assign higher numerical importance to a node which appears less frequently at lower level (Distance from the root of the tree) than the same nodes appearance at higher level and high frequency. To give an example, I want to give more significance to node Book, at level 2 appearing once, then at level 3 appearing thrice. Will appreciate any suggestions/pointers to techniques which achieve something similar. Thanks, Prateek

• Building a complete online payment gateway like Paypal

  - by John Stewart

  So this question isn't about integrating an existing payment gateway into my site. This is more of a architectural question. I want to build a system similar to Paypal. Now I understand that Paypal offers a lot of features under the roof and I can't implement all of them at once. I want to implement the core functionality of Paypal and other such services. So my question is (rather discussion is) around how would one go about building such a system. Some points to discuss: Handle payments through existing banks. I am guessing that I would need access to local bank protocols to get this. Allow users to securely store and process their payments How does Paypal handle the transactions? Thoughts?

• Quick backup system for large projects

  - by kamziro

  I've always backed up all my source codes into .zip files and put it in my usb drive and uploaded to my server somewhere else in the world.. however I only do this once every two weeks, because my project is a little big. Right now my project directories (I have a few of them) contains a hierarchy of c++ files in it, and interspersed with them are .o files which would make backing up take a while if not ignored. What tools exist out there that will let me just back things up efficiently, conveniently and lets me specify which file types to back up (lots of .png, .jpg and some text types in there), and which directories to be ignored (esp. the build dirs)? Or is there any ingenious methods out there that people use?

• Memory footprint of a parsed XML file in Classic ASP?

  - by Pete Duncanson

  Anyone know of a way to find out the amount of memory/size of a XMLDocument once it has parsed a XML file? I've been doing "beer mat" calculations so far but have been asked to come up with some more legit numbers through monitoring some how. I need to create about 1500 XML files (via FreeThreadedXMl-DOM object), which verge between 3-9K in size and store them in Application vars but our SysAdmin is worried about us gobbling up too much memory. Other than the crude method of booting up a fresh IIS instance and then loading everything in and monitoring before and after memory usage in Task Manager I can't think of a way of doing it with a bit more accuracy.

• TileMap in Sprite kit tile size issue

  - by TazmanNZL

  I am loading a TMX tile map into sprite kit using JSTileMap and the issue I am having is that if I use a tileSet.png the tiles appear too big when displayed. If I use a [email protected] the tiles appear the correct size but my tmx map does not show correctly instead all I see is the tileSet in a grid. I have tried renaming the [email protected] to tileSet.png but once again the tiles appear too big. Can I use a [email protected] with JSTileMap? The tiles in both png files are 128x128 Any help is appreciated.

• Development deployment: how to achive edit-and-reload with JSP pages?

  - by doublep

  Out project uses WebLogic as web-server and uses mostly JSP for user interface. With standard setup it is possible to copy edited JSP files into the exploded deployment directory and WebLogic will automatically pick them up, recompile and serve new content through HTTP. However, is it possible to avoid copying at all, so that I just save a file in my editor and it is immediately (well, after a couple of seconds for recompilation) visible? The project uses Apache Ant as building tool. I would imagine what I want would be possible with symlinks (since this is for deployment only I don't care about cross-platformity), but then I don't see how it is possible to symlink lots of files at once with Ant. So, how do I achieve save-JSP-hit-F5-in-browser functionality either with some setting in WebLogic; or with symlinking JSPs using Apache Ant (instead of copying them as is done now); or something else completely?

• Custom certificate as proof of transaction

  - by Andy

  I'm developing a site where a user conducts a given transaction and once completed, the user is issued with a 'secure certificate'. The certificate serves as proof of the transaction and the user is able to upload the certificate at a later stage, to view the details of the transaction. At the moment I'm using a custom XML document with encrypted fields. It works perfect, but I would like a standardized approach, such as an X.509 certificate. I'm no encryption expert, but from what I gather, X.509 is more geared towards SSL issued by a CA. Is it possible to create your own valid valid CRT file? As a test, I created a CRT file with the example provided on WikiPedia. However, when I open the file in Windows I get this warning: Invalid Public Key Security Object File - This file is invalid as the following: Security Certificate. Not having much luck here, so time to ask the experts. What direction should I be heading in? Any guidance would be greatly appreciated.

• Cygwin bash syntax error - but script run perfectly well in Ubuntu

  - by Michael Mao

  #!/bin/bash if test "$#" == "4"; then echo "$*"; else echo "args-error" >&2; fi; This little code snippet troubles me a lot when I tried to run it on both Ubuntu and Cygwin. Ubuntu runs bash version 4.0+ whereas Cygwin runs 3.2.49; But I reckon version collision shall not be the cause of this, this code runs well under fedora 10 which is also using bash version 3.+ So basically I am wondering if there is a way to code my script once and for all so there are not to have this awful issue later on. Many thanks in advance.

• python appengine form-posted utf8 file issue

  - by khany

  hi, i am trying to form-post a sql file that consists on many INSERTS, eg. INSERT INTO `TABLE` VALUES ('abcdé', 2759); then i use re.search to parse it and extract the fields to put into my own datastore. The problem is that, although the file contains accented characters (see the e is a é), once uploaded it loses it and either errors or stores a bytestring representation of it. Heres what i am currently using (and I have tried loads of alternatives): form = cgi.FieldStorage() uFile = form['sql'] uSql = uFile.file.read() lineX = uSql.split("\n") # to get each line and so on. has anyone got a robust way of making this work? remember i am on appengine so access to some libraries is restricted/forbidden

• Processing file uploads before object is saved

  - by Dominic Rodger

  I've got a model like this: class Talk(BaseModel): title = models.CharField(max_length=200) mp3 = models.FileField(upload_to = u'talks/', max_length=200) seconds = models.IntegerField(blank = True, null = True) I want to validate before saving that the uploaded file is an MP3, like this: def is_mp3(path_to_file): from mutagen.mp3 import MP3 audio = MP3(path_to_file) return not audio.info.sketchy Once I'm sure I've got an MP3, I want to save the length of the talk in the seconds attribute, like this: audio = MP3(path_to_file) self.seconds = audio.info.length The problem is, before saving, the uploaded file doesn't have a path (see this ticket, closed as wontfix), so I can't process the MP3. I'd like to raise a nice validation error so that ModelForms can display a helpful error ("You idiot, you didn't upload an MP3" or something). Any idea how I can go about accessing the file before it's saved? p.s. If anyone knows a better way of validating files are MP3s I'm all ears - I also want to be able to mess around with ID3 data (set the artist, album, title and probably album art, so I need it to be processable by mutagen).

• What's the (hidden) cost of lazy val? (Scala)

  - by Jesper

  One handy feature of Scala is lazy val, where the evaluation of a val is delayed until it's necessary (at first access). Ofcourse a lazy val must have some overhead - somewhere Scala must keep track of whether the value has already been evaluated and the evaluation must be synchronized, because multiple threads might try to access the value for the first time at the same time. What exactly is the cost of a lazy val - is there a hidden boolean flag associated with a lazy val to keep track if it has been evaluated or not, what exactly is synchronized and are there any more costs? And a follow-up question: Suppose I do this: class Something { lazy val (x, y) = { ... } } Is this the same as having two separate lazy vals x and y or do I get the overhead only once, for the pair (x, y)?

• Oauth callback problem

  - by yogsma

  I am using OAuth with google data api. We have a portal only for authorized users. So when users are logged in and if they are accessing calendar page, they will be asked if they want to sync their calendars with google calendar. If yes, they will be redirected for authentication. Once user has granted access, google appends OAuth_Token to the callback URL. the callback URL was that of the page of calendar in portal. This url has its query string options encrypted. But when the redirection happens , it takes back to login page of url. url is like http://aaa.xyz.com/(encrypted part of query string) and after oauth_token is authorized, this url becomes http://aaa.xyz.com/(encrypted part of query string)&oauth_token. So the user sees the login page after redirection instead of original page. How should I handle this in code.

• Default taglibs used within included JSPs for editing

  - by lostiniceland

  Hello everyone Within Eclipse's jsp-editor, as you all know, I get code-assistance for external taglibs once I defined them. In the project I am working on now a lot of jsps are just included and have no taglib definition in the top which gives me a lot of editor warnings. In the deployment this doesnt matter because the taglibs are defined in the head-jsp. Is there a way that I can define default taglibs within a project so the eclipse editor will give me code-assist even though I dont include the taglib in each file again?

• SharePoint Permissions

  - by Greg

  I have a custom workflow. This workflow removes permissions to items when an item is added (example an item is added by a service account and once added those permissions need to be removed from that item). This works as I have the service account 'hard coded' in the custom workflow. Now I would like to remove this hard coding and when a item is added to a list I would like to iterate through all users that have access to the list item. If a user matches some algorithm then remove that user from the item permissions which will be 0 to many. The piece I'm stuggling with is how to iterage all users with permission to a SPListItem. Any thoughts on how to accomplish this? Thanks in advance!
