• Handling big user IDs returned by FQL in PHP

  - by ggambett

  I'm using FQL to retrieve a list of users from Facebook. For consistency I get the result as JSON. This causes a problem - since the returned JSON encodes the user IDs as numbers, json_decode() converts these numbers to floating point values, because some are too big to fit in an int; of course, I need these IDs as strings. Since json_decode() does its own thing without accepting any behavior flags, I'm at a loss. Any suggestions on how to resolve this?

• BULK INSERT with inconsitant number of columns

  - by aceinthehole

  I am trying to load a large amount data in SQL server from a flat file using BULK INSERT. However, my file has varying number of column, for instance the first row contains 14 and the second contains 4. That is OK, I just want to make a table with the max number of columns and load the file into it with nulls for the missing columns. I can play with it from that point. But it seems that SQL Server when reaching the end of the line and having more columns to fill for that same row in the destination table, just moves on to the next line and attempts to put the data on that line to the wrong column of the table. Is there a way to get the behavior that I am looking for? Is there a table hint that I can use the specify this? Has anyone run into this before? Here is the code BULK INSERT #t FROM '<path to file>' WITH ( DATAFILETYPE = 'char', KEEPNULLS, FIELDTERMINATOR = '#' )

• Regex: absolute url to relative url (C#)

  - by splatto

  I need a regex to run against strings like the one below that will convert absolute paths to relative paths under certain conditions. <p>This website is <strong>really great</strong> and people love it <img alt="" src="http://localhost:1379/Content/js/fckeditor/editor/images/smiley/msn/teeth_smile.gif" /></p> Rules: - If the url contains "/Content/" I would like to get the relative path - If the url does not contain "/Content/", it is an external file, and the absolute path should remain Regex unfortunatley is not my forte, and this is too advanced for me at this point. If anyone can offer some tips I'd appreciate it. Thanks in advance.

• Static struct in C++

  - by pingvinus

  Hi, I want to define an structure, where some math constants would be stored. Here what I've got now: struct consts { //salt density kg/m3 static const double gamma; }; const double consts::gamma = 2350; It works fine, but there would be more than 10 floating point constants, so I doesn't want to wrote 'static const' before each of them. And define something like that: static const struct consts { //salt density kg/m3 double gamma; }; const double consts::gamma = 2350; It look fine, but I got these errors: 1. member function redeclaration not allowed 2. a nonstatic data member may not be defined outside its class I wondering if there any C++ way to do it?

• Mapping Hilbert values to 3D points

  - by Alexander Gladysh

  I have a set of Hilbert values (length from the start of the Hilbert curve to the given point). What is the best way to convert these values to 3D points? Original Hilbert curve was not in 3D, so I guess I have to pick by myself the Hilbert curve rank I need. I do have total curve length though (that is, the maximum value in the set). Perhaps there is an existing implementation? Some library that would allow me to work with Hilbert curve / values? Language does not matter much.

• Can't type after "ruby script/server" in InstantRails

  - by mathee

  I'm a newb to RoR. I'm using the book "Agile Web Development with Rails" to get started on Windows 7. In the command window, I run the following. >rails demo >cd demo >ruby script/server At this point, it boots the Mongrel server: => Booting Mongrel => Rails 2.3.5 application starting on http://0.0.0.0:3000 => Call with -d to detach => Ctrl-C to shutdown server The book goes on to tell me to run ruby script/generate controller Say but, I cannot Ctrl-C -- or type anything for that matter -- after booting the Mongrel server. Am I supposed to create the new controller in another instance of the InstantRails command window? Right now, the only way I can stop the server is closing the window in which I started the server! Please let me know if you need any other details. tia.

• Mercurial How To Merge 2 Repositories that share a common ancestor but are not clones of the same re

  - by sylvanaar

  I am using hg-subversion, and I have 2 different hg repositories one from our svn trunk, and one from a branch of the trunk. I would like to link them somehow. At some point in the history both Hg repositories will be identical is there some way to join them? In other words is there a way to relate the repositories from within Hg? The technique I am currently using is to just export the second repository over top of the working copy of the revision they share, and then commit that working copy as a branch in Hg, but I lose the history this way. Any advice would be great

• what's the purpose of fcntl with parameter F_DUPFD

  - by Daniel

  I traced an oracle process, and find it first open a file /etc/netconfig as file handle 11, and then duplicate it as 256 by calling fcntl with parameter F_DUPFD, and then close the original file handle 11. Later it read using file handle 256. So what's the point to duplicate the file handle? Why not just work on the original file handle? 12931: 0.0006 open("/etc/netconfig", O_RDONLY|O_LARGEFILE) = 11 12931: 0.0002 fcntl(11, F_DUPFD, 0x00000100) = 256 12931: 0.0001 close(11) = 0 12931: 0.0002 read(256, " # p r a g m a i d e n".., 1024) = 1024 12931: 0.0003 read(256, " t s t p i _ c".., 1024) = 215 12931: 0.0002 read(256, 0x106957054, 1024) = 0 12931: 0.0001 lseek(256, 0, SEEK_SET) = 0 12931: 0.0002 read(256, " # p r a g m a i d e n".., 1024) = 1024 12931: 0.0003 read(256, " t s t p i _ c".., 1024) = 215 12931: 0.0003 read(256, 0x106957054, 1024) = 0 12931: 0.0001 close(256) = 0

• Single SignOn - Best practice

  - by halfdan

  Hi Guys, I need to build a scalable single sign-on mechanism for multiple sites. Scenario: Central web application to register/manage account (Server in Europe) Several web applications that need to authenticate against my user database (Servers in US/Europe/Pacific region) I am using MySQL as database backend. The options I came up with are either replicating the user database across all servers (data security?) or allowing the servers to directly connect to my MySQL instance by explicitly allowing connections from their IPs in my.cnf (high load? single point of failure?). What would be the best way to provide a scalable and low-latency single sign-on for all web applications? In terms of data security would it be a good idea to replicate the user database across all web applications? Note: All web applications provide an API which users can use to embed widgets into their own websites. These widgets work through a token auth mechanism which will again need to authenticate against my user database.

• Strange beep when using cout

  - by Unknown

  Hello everyone, today when I was working on some code of mine I came across a beeping sound when printing a buffer to the screen. Here's the mysterious character that produces the beep: '' I don't know if you can see it, but my computer beeps when I try to print it like this: cout<<(char)7<<endl; Another point of interest is that the 'beep' doesn't originate from my on board beeper, but from my headphone/speaker Is this just my computer or there something wrong with the cout function? EDIT: But then why does printing this character produce the beep sound? does that mean that I could send other such characters through the cout function to produce different effects?

• Prepend 'www' to an HTTPS url using .htaccess & mod_rewrite

  - by webfac

  I have a dilemma with this one. With the following code I am able to force SSL on any non SSL url, however when the user (and results from Google) take the user to http://mysite.co.za then we hit an issue as the url is then rewritten to https://mysite.co.za Due to the fact that my certificate is bound to www.mysite.co.za it immediately throws a security error because of the missing 'www' in the url. Can someone point out a way to add the www to the domain when the domain starts with HTTPS and not HTTP? Much appreciated. And the current code to add the https:// is as follows: RewriteCond %{HTTP_HOST} !^www\. RewriteCond %{HTTPS}s ^on(s)| RewriteRule ^ http%1://www.%{HTTP_HOST}%{REQUEST_URI} [L,R=301]

• Exporting Eclipse project with a reference to native library

  - by TacB0sS

  I have an Eclipse project, that uses JMF, I found out I could skip the JMF installation process and still to use the CaptureDeviceManager of the JMF, and to receive the list of devices if I could point my project to the native lib of the JMF. I've managed to add the native lib to the IDE run/debug, but once I export the application to an external runnable Jar, the application cannot find the native lib. the files are located in c:\JMF*.dll I tried to add the folder path to the environment variable in windows - didn't work. I tried to add them into another Jar and add it to the project - didn't work. I tried to add the files into the project - didn't work. I tried to add the path to the class path - didn't work. I tried to add the path to the library path - didn't work. does someone have any sort of a solution? Thanks in advance, Adam Zehavi.

• PHP auto refresh page without losing user input

  - by Tony

  I'm working on a PHP collaboration software project. I have a page that shows the latest updates from other users who are adding content to the database, but also has a form input to allow the user to enter text. I am currently using this code to refresh the page automatically every 30 seconds: header('Refresh: 30'); The problem is that the header code refreshes the entire page, and not just what is pulled from the database. Is there any PHP code that will just pull any new data from the database without refreshing the entire page? If someone could point me in the right direction I'd appreciate it.

• Is it actually possible to connect to ActiveMQ via XMPP and query/browse queues using "AciveMQ.Agen

  - by Oleg Kiorsak

  I tried what I think are 4 most popular XMPP (aka "Jabber") clients (Spark, Pidgin, Psi, Pandion) to connect to ActiveMQ instance (Apache ActiveMQ ver. 5.3.0) on XMMP connector with an idea to use the "AciveMQ.Agent chatroom" for querying queues/etc and no success at all Some of them fail with 'Unknown error', some don't fail but kind of "hang"... interestingly, some communication does indeed reach the ActiveMQ side, because when I close a client it spits an exception "could not close" or something to that effect... and if I try "register new user" option (present on most clients" the ActiveMQ also spits some most cryptic warning message But I was never able to get to the point when I could see or specify "ActiveMQ.Agent" as chatroom and issue any commands... Before I waste any more time on this curious feature, I would like to hear whether anyone had any success with it? Thank you! PS: BTW, the book "ActiveMQ in Action book" http://www.manning.com/snyder/ shows that it is apparently works and is very easy using some Mac client (AdiumX), but I wanted it on a Windows PC ;)

• How do you update the server name in source indexed symbol file?

  - by Keith Hill

  With the Debugging Tools for Windows you can run SSIndex.cmd against your symbol files and it will embed the command to retrieve each source code file from the TF server. We have a bunch of indexed files and recently our IT migrated our TFS 2008 installation to TFS 2010 and in the process changed the server name. Question is, how can I update all these symbol files to point to the new server? I thought SSindex used an alternate data stream named 'srcsrv' but SysInternals' streams.exe shows nothing on these symbol files even though srctool.exe shows the data.

• Reading what is in the vsdiagnostics blob in Azure (1.7)

  - by tomasmcguinness

  I've enabled Diagnostics in one of my Worker roles and published it to Azure. There was a new blob container created called "vsdiagnostics" and contained within in are two binary files. I'm assuming that these files contain the output of my Trace statements, but I'm unable to open these files as I have no idea what format they are in. I've not found anything on www.windowsazure.com about it and most of the tools they recommend are very outdated. I have installed Cerebrata's Azure Diagnostics Manager, but that isn't able to load the Trace Logs. If anyone could point me in the right direction I'd be grateful!

• How to check whether the form has any ShowDialog() forms open?

  - by kornelijepetak

  I have a form MainForm with several properties/methods that are accessed from another thread. At some point I might open a form AuxForm with ShowDialog() and then while that modal form is open, the other thread still modifies the MainForm's properties. This is all desired. In one of the methods accessed from another thread I need to execute some code, but only if the modal AuxForm is not open. Is there any way to check this (by using .NET WF Form properties) or I need to use a flag variable? NOTE: None of these properties/methods modify the controls (so no Invoke is required).

• onclick event not working after ie7 reload

  - by Charles

  I am using Javascript to dynamically create part of my page content. A routine that generates a set of img tags is called from the window.onload event. Those img tags are assigned attributes, including an onclick event. The img tags host thumbnail images that, when clicked, change the src property of the image in the main view div. Everything works properly in FF 3.5. I can reload the page and the dynamically generated onclick events continue to fire as expected. In IE7 everything works normally until I reload the page. At that point events that were hard coded into the xhtml section continue to work as expected, and the dynamically generated img tags are shown on the page, but their onclick events fail to work. How can I get IE7 to implement the dynamically generated click events on reload?

• Custom dropdown for CComboBox

  - by WalderFrey

  I'm trying to create a custom dropdown for a derivative of CComboBox. The dropdown will be a calendar control plus some 'hotspots', e.g. So I figure the best way to achieve this is to have a simple CWnd-derived class which acts as the parent to the calendar control, and have it paint the hotspots itself. The window needs to be a popup window - I think - rather than a child window so that it isn't clipped. But doing this causes the dialog (on which the combobox control is placed) to stop being the topmost (foreground?) window, leading to its frame being drawn differently: This spoils the illusion that the dropdown is part of the combobox since its acting more like a modal dialog at this point. Any suggestions on how I make the custom dropdown behave like the regular dropdown? Are there any other pitfalls I need to watch out for, e.g. focus and mouse capture issues?

• Can I programatically determine if a PNG is animated?

  - by alex

  I have PNG (as well as JPEG) images uploaded to my site. They should be static (i.e. one frame). There is such thing as APNG. (it will be animated in Firefox). According to the Wikipedia article... APNG hides the subsequent frames in PNG ancillary chunks in such a way that APNG-unaware applications would ignore them, but there are otherwise no changes to the format to allow software to distinguish between animated and non-animated images. Does this mean it is impossible to determine if a PNG is animated with code? If it is possible, can you please point me in the right direction PHP wise (GD, ImageMagick)?

• Visual Studio Add-in - How do I create an Installer?

  - by Morgeh

  I have made a Visual Studio Add-in as part of a project I'm working on using web services. When I created the new Add-in project in visual studio it generated all the code required and installed the blank add-in on my pc (I assume). Since this is a large project we are using svn to manage the code base and once I had done some of the work on the Add-in I commited it, then checked it out on a different pc and attempted to run it. However on the other pc when I run the add-in in debug mode, the tools entry for the add-in is not present and I can't run the add-in. Am I right in assuming that when I created the project on the other pc it installed the plugin aswell?? and does that mean that I will need to create an installer for any other pcs I wish to use? Obviously at some point I intend on making an installer anyway but not untill after the development of the addin is complete.
