• Facebook javascript in address bar, possible to replicate?

  - by DoMx

  This is my first experience with stackoverflow and I'm afraid my question asks of a lot for a first. I was looking at this thread: http://stackoverflow.com/questions/2634159/javascrypt-in-the-adress-bar-is-this-malicious and as you will see SLaks has very kindly deobfuscated the javascript and left us with what appears as the Javascript behind the automatic facebook invite code. As I'm fairly new to javascript, I was wondering, what other components were needed to get this code to work? You of course have the functions there and they are called by the obfuscated javascript but how exactly? Would it be possible to replicate this on a page of my own using the information available or is there more to this script I am missing? I am willing to financially assist somebody who could compile a solution for me. Thank you in advance.

• Node.js and wss://

  - by CNelson

  I'm looking to start using javascript on the server, most likely with node.js, as well as use websockets to communicate with clients. However, there doesn't seem to be a lot of information about encrypted websocket communication using TLS and the wss:// handler. In fact the only server that I've seen explicitly support wss:// is Kaazing. This TODO is the only reference I've been able to find in the various node implementations. Am I missing something or are the websocket js servers not ready for encrypted communication yet? Another option could be using something like lighttpd or apache to proxy to a node listener, has anyone had success there?

• ASP.NET and IsNew on the page level

  - by tyndall

  Never seen this before in ASP.NET development. I'm trying to refactor out 40 single-page ASP.NET pages to code-behind style. What does this code do? // Validate required parameters (if "new", then nothing is required) if (!this.IsNew()) { if (string.IsNullOrEmpty(_billId)) { responseErrorNo = 4; Utils.SendError(respErrNum); } } Its on a single-page design ASP.NET page in the block in the Page_Load method. On a code-behind page this code ( .IsNew) is not recognized. What am I missing here? Is there an MSDN page on IsNew of the "page"?

• Connecting Ingres from C

  - by avesus

  I need to connect to an Ingres supplied demodb through OpenAPI, both Ingres and C application running on windows. What i have done: Created a "node" in the Ingres Network Utility named "usernode". created user accounts in the Ingres installation (named "user" password "user") and in the Windows user management (the same creds.) Granted necessary privileges to the user in the database. In C code i have called IIapi_connect() function with an IIAPI_CONNPARM structure. Used members: co_target = "usernode::demodb", co_username = "user", co_password = "user" But IIapi_connect() call returns an error: "User provided a vnode as part of the database name (vnode::dbname), but connection information for that vnode is missing. Enter connection information for the vnode using NETUTIL." Anybody knows something that is a weird concept "node"? What are the minimum steps (in the database administration and the function parameters passing) necessary for the successful connect?

• How can I make my tableview enter editing mode?

  - by Jake

  Hi, for some reason I can't get my tableview to enter editing mode. It's a little harder than it might seem because I'm using some open source code to make a calendar (iCal esque) with a tableview under it, and it's not quite as straightforward as just using a regular tableview. Basically, I have two classes. One (let's say Class A) is a UIViewController and the other (Class B) is that viewController's datasource and tableview delegate. In Class B, I've implemented -(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath; which works fine, but if I put an edit nav bar item in Class A (the view controller), nothing happens. Am I forgetting certain protocols, or certain special methods that I need to write? Thanks for any help, and apologies if I'm missing something, I'm just learning to work with other people's code.

• DataGridView and checkboxes re-selecting automatically

  - by SuperFurryToad

  I have a strange problem with a DataGridView I'm using which is bound to a table in VB.net I've added a checkbox column to allow a user to tick a bunch of rows that I can then loop through and save off to a different table. All the checkboxes are enabled by default. So it's really a case of unchecking the rows which aren't required. However, the DataGridView re-enables any checkbox that I click after I click on a checkbox in another row. So in effect, only one row can be unchecked at a time. I'm sure I'm probably missing something obvious here?

• Rails ActiveRecord- has_many through and belongs_to a related model

  - by Nick

  I have 3 models sites, user_favorites and users. Relevant relationships: class Site < ActiveRecord::Base has_many :users, :through => :user_favorites class UserFavorite < ActiveRecord::Base belongs_to :user, :counter_cache => true belongs_to :site end class User < ActiveRecord:Base has_many :user_favorites has_many :sites, :through => :user_favorites All of that works just fine. I'd like to add a new attribute to the Site model to indicate which user created it. I don't believe this constitutes a has_and_belongs_to_many scenario. A site has many users through user_favorites but I want it to belong to a single user reflecting the owner/creator. I'm wondering what the ORM best practice is for this. SQL wise I'd just use different joins depending on what I was trying to query with a created_by FK in Site. Sorry if I'm missing something basic here. Thanks

• MD5 hash differences between Python and other file hashers

  - by Sam

  I have been doing a bit of programming in Python (still a n00b at it) and came across something odd. I made a small program to find the MD5 hash of a filename passed to it on the command line. I used a function I found here on SO. When I ran it against a file, I got a hash "58a...113". But when I ran Microsoft's FCIV or the md5sum.py in \Python26\Tools\Scripts\, I get a different hash, "591...ae6". The actual hashing part of the md5sum.py in Scripts is m = md5.new() while 1: data = fp.read(bufsize) if not data: break m.update(data) out.write('%s %s\n' % (m.hexdigest(), filename)) This looks functionally identical to the code in the function given in the other answer... What am I missing? (This is my first time posting to stackoverflow, please let me know if I am doing it wrong.)

• Printer Communication Capture

  - by D-S

  If I need to post this elsewhere let me know. We have some old software thats being re-written, that uses a printerdriver to a propriatery printer. I need to rewrite the software bypassing the print driver and go directly to the printer. I do have the specs for the printer communication, thats fine, but what Id like to do is monitor the communications to the printer to view its contents (from the existing software that Im re-writing) and compare it to the specs, and what I will be sending it for validation. I have to make sure Im not missing anything. Any ideas on how I might be able to accomplish this? Thanks

• Taking web page screen shot in Windows 8 Metro app

  - by Megan

  I'm trying to take screen shot of web page in Windows 8 Metro app. So far the only helpful control is the WebView. Unfortunately it does not contain any method like DrawToBitmap (known from Forms WebBrowser control). Am I missing something? Different approach would focus on injecting some JS (e.g. html2canvas) to page rendered in WebView but I don't think it is possible due to security reasons. I would greatly appreciate any help.

• Sometimes, scaling down a bitmap generates a bigger file. Why?

  - by Matías

  Hello, I'm trying to write a method to reduce the size of any image 50% each time is called but I've found a problem. Sometimes, I end up with a bigger filesize while the image is really just half of what it was. I'm taking care of DPI and PixelFormat. What else am I missing? Thank you for your time. public Bitmap ResizeBitmap(Bitmap origBitmap, int nWidth, int nHeight) { Bitmap newBitmap = new Bitmap(nWidth, nHeight, origBitmap.PixelFormat); newBitmap.SetResolution(origBitmap.HorizontalResolution, origBitmap.VerticalResolution); using (Graphics g = Graphics.FromImage((Image)newBitmap)) { g.InterpolationMode = InterpolationMode.HighQualityBicubic; g.DrawImage(origBitmap, 0, 0, nWidth, nHeight); } return newBitmap; }

• Resharper 5 - enable/disable on the fly

  - by Cristi Diaconescu

  I want to disable ReSharper 5 when debugging - it slows things down more than I'm willing to take. Is there an automatic way to do this? The next best thing would be a toolbar button to manually enable/disable it. On the Tools - Options - ReSharper page there's a comment that the VS command Resharper_ToggleSuspended would do just this. The problem is, I can't find the command when I right-click a toolbar - Customize... - 'Commands' tab - Choose 'Resharper' category. Am I missing something?

• Defining tokens at runtime

  - by Peter Crenshaw

  I want to write a parser for EDIFACT messages with JavaCC. My problem is that I cannot define all terminal symbols before parsing a message because at the begining of each message there is a so called "Advice Segment" ("UNA" Segment) which defines things like element seperator symbol, escape symbol, segment terminator symbol and decimal notation (e.g. '.' or ','). So I think/guess the production rules need some kind of variables which must be set at runtime during parsing. Can this be done with JavaCC and if so how? Or is there another way I am missing?

• How to find date ranges in records with consecutive dates and duplicate data

  - by alan s

  There's probably any easy solution for this, but I can't see it. I have a table with consecutive dates and often duplicate associated data for several of these consecutive dates: Date Col1 Col2 5/13/2010 1 A 5/14/2010 1 A 5/15/2010 2 B 5/16/2010 1 A 5/17/2010 1 A 5/18/2010 3 C 5/19/2010 3 C 5/20/2010 3 C Using MS T-SQL, I wish to find the start and end dates for each run of distinct Col1 and Col2 values: StartDate EndDate Col1 Col2 5/13/2010 5/14/2010 1 A 5/15/2010 5/15/2010 2 B 5/16/2010 5/17/2010 1 A 5/18/2010 5/20/2010 3 C Assumptions: There are never any missing dates. Col1 and Col2 are not null. Any ideas - preferably that don't use cursors? Many thanks, -alan

• Upgrading PEAR in command prompt: "Error:Failed to mkdir C:\..."

  - by noscript

  I've just installed PEAR into WAMP attempting to follow this article. It all seems to have gone okay but when I type "pear upgrade" into the command prompt I get this error: ERROR: failed to mkdir c:\php\pear\docs\Archive_Tar\docs It is looking on the wrong drive (and missing a subdirectory in that path by the looks of it). It should be looking for D:\php\php5.3.13\pear\docs\Archive_Tar\docs When specifying installation directories I chose ones on the D:\ and thats where the folder structure is, the include_path in both php.ini locations have also been updated. I've also reset the WAMP server after making the changes. How do I set it to look / install the package in the right place?

• functions in F# .. why is it not compiling

  - by Tanmoy

  Hi, I have written two versions of code. The first one works as expected and print "Hi". the second one gives me error that "block following this let is unfinished" 1st version #light let samplefn() = let z = 2 let z = z * 2 printfn "hi" samplefn() 2nd version #light let samplefn() = let z = 2 let z = z * 2 samplefn() Only difference is the printfn is absent in the second version. I am using Visual Studio 2010 as my IDE. I am very new to F# but this error seems very strange to me. I guess I am missing some very important concept. Please explain. Edit: Also if I do it outside the function I get error even with the first version of code. #light let z = 2 let z = z * 2 printfn "Error: Duplicate definition of value z"

• iPhone post-processing with a single FBO with Opengl ES 2.0?

  - by Jing

  I am trying to implement post-processing (blur, bloom, etc.) on the iPhone using OpenGL ES 2.0. I am running into some issues. When rendering during my second rendering step, I end up drawing a completely black quad to the screen instead of the scene (it appears that the texture data is missing) so I am wondering if the cause is using a single FBO. Is it incorrect to use a single FBO in the following fashion? For the first pass (regular scene rendering), I attach a texture as COLOR_ATTACHMENT_0 and render to a texture. glFramebufferTexture2D(GL_FRAMEBUFFER, GL_COLOR_ATTACHMENT0, GL_TEXTURE_2D, texturebuffer, 0) For the second pass (post-processing), I attach the color renderbuffer to COLOR_ATTACHMENT_0 glFramebufferRenderbuffer(GL_FRAMEBUFFER, GL_COLOR_ATTACHMENT0, GL_RENDERBUFFER, colorRenderbuffer) Then use the texture from the first pass for rendering as a quad on the screen.

• PHP getting blank pages after submit a form + signal Segmentation fault (11)

  - by Ole Media

  I few days ago I update my macbook pro to snow leopard, and since then some php files are not showing. This is what happens: I created a php form, when going to 'http://localhost/webform.php' I can see the form just fine. Then, once I submit the form, I just get a blank page. I enable error and warnings reporting under php.ini to make sure I'm not missing something, but still I'm not getting anything, just the blank page. Then I checked under apache log files, and what I notice is that every time I submit the form I see the following line coming up under the apache logs: [Wed Apr 07 21:40:28 2010] [notice] child pid 70223 exit signal Segmentation fault (11) I'm clueless on this one. Any ideas on how to fix it?

But why is that icon missing? Thanks in advance :)

• Backbone.js - Getting JSON back from url

  - by Brian

  While trying to learn Backbone.js, I've been trying to grab the content of a JSON file using the following code: (function($){ var MyModel = Backbone.Model.extend(); var MyCollection = Backbone.Collection.extend({ model : MyModel, url: '/backbone/data.json', parse: function(response) { console.log(response); return response; } }); var stuff = new MyCollection; console.log(stuff.fetch()); console.log(stuff.toJSON()); })(jQuery) 'stuff.fetch()' returns the entire object (with the data I'm after in responseText), 'stuff.toJSON' returns nothing ([]), but the console in the parse method is returning exactly what I want (the json object of my data). I feel like I'm missing something obvious here, but I just can't seem to figure it out why I can't get the right data out. Could someone point me in the right direction or show me what I'm doing wrong here? Am I using a model for the wrong thing?

• How to implement User routing like that in StackOverflow ?

  - by rockinthesixstring

  I've looked at the routing on StackOverflow and I've got a very noobie question, but something I'd like clarification none the less. I'm looking specifically at the Users controller http://stackoverflow.com/Users http://stackoverflow.com/Users/Login http://stackoverflow.com/Users/124069/rockinthesixstring What I'm noticing is that there is a "Users" controller probably with a default "Index" action, and a "Login" action. The problem I am facing is that the login action can be ignored and a "UrlParameter.Optional [ID]" can also be used. How exactly does this look in the RegisterRoutes collection? Or am I missing something totally obvious? EDIT: Here's the route I have currently.. but it's definitely far from right. routes.MapRoute( _ "Default", _ "{controller}/{id}/{slug}", _ New With {.controller = "Events", .action = "Index", .id = UrlParameter.Optional, .slug = UrlParameter.Optional} _ )
