• Facebook Is it possible to grab a user's data and populate a form in an iframe?

  - by super9

  I am trying to create an iframe tab for a Facebook Page. On this page, I am loading in an iframe which consists of a form from another domain/site. Is it possible to use javascript to query the graph api to load the user's data into this iframe loaded form using javascript such that is appears pre-populated to the user? I am aware that there is a cross domain security issue. In that case, suppose that my iframe tab is now hosted on the same domain as the iframe loaded form, will this be doable now?

• Android back button does not restart activity?

  - by Chris

  My app intiates an activity. On the click of a button, the app opens up the browser with a webpage. When I hit the back button, it comes back to my initial activity screen, but does not resume or restart the activity. When I put all the layout code and activity code in onResume instead of onCreate, the activity gets restarted. My question is whether this is the right way to go about it? Can I use onResume to draw my layout and initiate the activity, or is this poor design? When the browser fires up, does the initial activity forget its layout? Please let me know what you suggest. Thanks Chris

• Using clojure.contrib functions in slime REPL

  - by Tyler

  I want to use the functions in the clojure.contrib.trace namespace in slime at the REPL. How can I get slime to load them automatically? A related question, how can I add a specific namespace into a running repl? On the clojure.contrib API it describes usage like this: (ns my-namespace (:require clojure.contrib.trace)) But adding this to my code results in the file being unable to load with an "Unable to resolve symbol" error for any function from the trace package. I use leiningen 'lein swank' to start the ServerSocket and the project.clj file looks like this (defproject test-project "0.1.0" :description "Connect 4 Agent written in Clojure" :dependencies [[org.clojure/clojure "1.2.0-master-SNAPSHOT"] [org.clojure/clojure-contrib "1.2.0-SNAPSHOT"]] :dev-dependencies [[leiningen/lein-swank "1.2.0-SNAPSHOT"] [swank-clojure "1.2.0"]]) Everything seems up to date, i.e. 'lein deps' doesn't produce any changes. So what's up?

• Windows disassembler: looking for a tool...

  - by SigTerm

  Hello. I'm looking for a (preferably free) tool that can produce "proper" disassembly listing from a (non-.NET) windows PE file (*.exe or *.dll). Important requirement: it should be possible to run the listing through a windows assembler (nasm, masm or whatever) and get working exe again (not necessarily identical to original one, but it should behave in the same way). Intended usage is adding new subroutines into existing code, when source is not available. Ideally, tool should be able to detect function/segment boundaries, API calls, and generate proper labels for jumps (I can live without labels for loops/jumps, though, but function boundary detection would be nice), and keep program resources/segments in place. I'm already aware of IdaPRO(not free), OllyDBG (useful for in-place hacking, doesn't generate disassembly listing, AFAIK), ndisasm (output isn't suitable for assembler), dumpbin (useful, but AFAIK, output isn't suitable for assembler) and "proxy dll" technique. Ideas? Or maybe there is a book/tutorial that explains some kind of alternative approach?

• FIPS-compliant encryption in .NET 2.0

  - by Odrade

  We have a .NET 2.0 application that uses the RijindaelManaged class to encrypt some sensitive data. This was fine until we ran into some machines that require the use of FIPS-compliant algorithms. We'd like to switch to AesCryptoServiceProvider, but most of our target machines haven't upgraded past .NET 2.0. Requiring an upgrade is out of the question. After all, upgrades are scary! Is there any way we could use AesCryptoServiceProvider in a .NET 2.0 application? Since 3.5 uses the 2.0 CLR, I was hoping there might be a way to build the needed libraries into the app. Failing that, could someone point me to a reference on the native API that's wrapped by AesCryptoServiceProvider?

• Example code of libssh2 being used for port forwarding

  - by flxkid

  I'm looking for an example of how to use libssh2 to setup ssh port forwarding. I've looked at the API, but there is very little in the way of documentation in the area of port forwarding. For instance, using PuTTY plink, There is the remote port to listen on, but also the local port that traffic should be sent to. Is it the developers responsibility to do this part? Can an example be developed of this? Also, for the opposite, where a remote port is brought to a local port, do I use libssh2_channel_direct_tcpip_ex? What about an example of this? I really need to do this exact thing on a project right now. How hard would it be to develop a couple of samples of this? I'm willing to put up a bounty if need be to get a couple of working examples of this.

• Using sphinx to create context sensitive html help

  - by bluebill

  Hi all, I am currently using AsciiDoc (http://www.methods.co.nz/asciidoc/) for documenting my software projects because it supports pdf and html help generation. I am currently running it through cygwin so that the a2x tool chain functions properly. This works well for me but is a pain to setup on other windows computers. I have been looking for alternative methods and recently revisited Sphinx. Noticing that it now produces html help files I gave it a try and it seems to work well in the small tests I performed. My question is, is there a way to specify map id's for context sensitive help in the text so that my windows programs can call the proper help api and the file is launched and opened to the desired location? In AsciiDoc I am using "pass::[]". By using these constructs a context.h and alias.h are generated along with the other html help files (context sensitive help information).

• UITextFields losing values after UINavigationController activity

  - by Dan Ray

  This is going to be hard to demonstrate in code, but maybe you can picture it with me. I have a view that contains two UITextFields, "title" and "descr". That same view contains two UIButtons that push another controller onto the navController to get more detail from the user about the object we're assembling and ultimately uploading to my server. It appears that pushing another view on, doing something, and popping it back off results in the two UITextFields keeping their content VISUALLY, but the .text property of those fields becomes NULL. I've confirmed that if I do my two push-pop fields before filling in those UITextFields, I get my data when I upload, and if I do them in the opposite order, I don't. It LOOKS like there's data there, but I get nothing when I NSLog their .text properties. Is this normal? Do I need to just design around this? Or is this as weird as it seems, and I should be looking deeper at causes of this?

• What is the correct way to specify dimensions in DIP from Java code ?

  - by Pavel Lahoda

  Trying to digest docs about design Multiple resolutions (http://d.android.com/guide/practices/screens_support.html#dips-pels) I found that it is possible to set dimensions of my interface elements in XML layouts using DIPs as in following fragment : "android:layout_width="10dip" But all Java interface takes integer as arguments and there is no way to specify dimensions in DIPs. What is the correct way to calculate this ? I figured that I have to use property density of DisplayMetrics class but is this a correct way ? May I relly that formula : pixels * DisplayMetrics.density = dip is always correct ? Will there be API in DIPs for Java ?

• iPhone -- initialization partly by NSKeyedUnarchiver and partly by other means

  - by William Jockusch

  I have an object myObj, which is an instance of a class MyClass. Some of its instance variables always have their initial values passed in by the calling code. Other instance variables will be initialized in one of two ways. For an instanceArray of type NSMutableArray, the possibilities are either instanceArray = [[NSMutableArray alloc]init]; or instanceArray = [someKeyedUnarchiver decodeObjectForKey: kInstanceArrayKey]; The calling code should determine which of the above will be used. Any particular design pattern I should prefer?

• Not-quite-JSON string deserialization in Python

  - by cpharmston

  I get the following text as a string from an XML-based REST API 'd':4 'ca':5 'sen':1 'diann':2,6,8 'feinstein':3,7,9 that I'm looking to deserialize into a pretty little Python dictionary: { 'd': [4], 'ca': [5], 'sen': [1], 'diann': [2, 6, 8], 'feinstein': [3, 7, 9] } I'm hoping to avoid using regular expressions or heavy string manipulation, as this format isn't documented and may change. The best I've been able to come up with: members = {} for m in elem.text.split(' '): m = m.split(':') members[m[0].replace("'", '')] = map(int, m[1].split(',')) return members Obviously a terrible approach, but it works, and that's better than anything else I've got right now. Any suggestions on better approaches?

• file path of a MenuItem target with cmdOpen action

  - by maranas

  I am trying to acquire the file path of an item within the NSMenuItem object. Using [objectname action] i am able to properly acquire the action (cmdOpen). But [objectname target] returns a null value. According to the documentation in the apple developer website, if the value is null, the action is sent to the first-responder. I want to be able to dynamically access the file path of the target file. Is there a way to do this without changing the program design?

• Google Maps: How to prevent InfoWindow from shifting the map

  - by TeddyN

  Using Google Maps API v3. I noticed that if I have a map marker near the edge of my map border ... that if I click the marker icon so that the InfoWindow will display, my entire map shifts so that the markers InfoWindow is centered. I don't want my map to shift. Question: How do I prevent the map from shifting when InfoWindows are near the end of the map border (which causes the InfoWindow by default to center & shift the map)?

• Blackberry - How to get Field Labels from PIMItem

  - by Taha

  How can we get Field Labels from PIMItem. The following code is with PIMList String label = pimList.getAttributeLabel( blackBerryContact.getAttributes(Contact.TEL, i)); But i have PIMItem. There is a method PIMItem.getPIMList() which returns null for me in the code below. THE API at http://www.blackberry.com/developers/docs/5.0.0api/index.html says "getPIMList() Gets the PIMList associated with this item." Below is sample code that i am trying to achive - // Load the address Book and allow the user to select a contact BlackBerryContactList contactList = (BlackBerryContactList) PIM.getInstance().openPIMList(PIM.CONTACT_LIST,PIM.READ_ONLY); PIMItem userSelectedContact = contactList.choose(); // Now get the Field labels for contact numbers for userSelectedContact

• Markup filter wanted for a public website

  - by sibidiba

  Developing a community site where everyone can post text, I'm looking for a markup filter: What is not part of the markup must be escaped (htmlspecialchars()) as it is. Should turn URL-s automatically into links Should support some form of basic markups (bold, image, url, pre, list) Should have a simple parser, that turns user input text into HTML Content on the site is public to everyone, XSS must not allowed to happen. What do you suggest? What markup language in the first place? BBCode? Wiki? Markdown? Are there any complete API-s with good examples? PHP is available on the server side. If there is a WYSIWYG-like texarea in addition (like here on SO) that would be a fantastic bonus!

• Graphical Programming Language

  - by prosseek

  In control engineering or instrumentation, I see Simulink or LabVIEW(G) is pretty popular. In ESL design, I see that Agilent SystemVue is gaining some popularity. If you see the well established compiler theroy, almost 100% is about the textual language. But how about the graphical language? Is there any noticable research or discussion about the graphical programming language? In terms of Theory about Graphical Language - syntactic/semantic analysis and whatever relevant expressiveness (Actually, I asked a question about it at SO - http://stackoverflow.com/questions/2427496/what-do-you-mean-by-the-expressiveness-in-programming-lanuguage) Possibility of the Graphical language ... Or what do you think about the Graphical Programming Language?

• Sync Services With AddressBook

  - by Marcus

  Hi, I've developed an application to sync the Mac address book with another application. I was using an NSNotification (kABDatabaseChangedExternallyNotification) which are sent every time the address book is edited to do the syncing. However I found that if I 'overloaded' the address book (by adding 20 records really quickly or something) I didn't get all of the notifications. I have since found the Sync Services framework which seems to be aimed at my kind of application and it seems to work fine. The problem is that the changes are not 'pushed' to me in the same was as an NSNotification - I have to sync every 5 minutes or so. And, from what I can understand, I shouldn't use the AddressBook API directly but push changes back through sync services. This means that changes are not instant but lagged by how often address book/my app syncs. Is there any way to make it instant? or to use the NSNotifications reliably? Thanks for your time, Marc

• android: customized text selector

  I wanted to design a customized text selector that changed the text color when user clicks the TextView.

• Windows secure pinned website tile

  - by Stijn de Voogd

  I'm currently working on a pinned website tile for my website and instead of using a static XML file i'm linking the tile to a web api that returns user specific XML. My question is: Is it possible to secure this tile so that a user needs to be logged in before the data loads? The pinned website livetile doesn't send any security request headers/ cookies: - Http: Request, GET /v1/livetile/firsttile Command: GET + URI: /v1/livetile/firsttile ProtocolVersion: HTTP/1.1 UserAgent: Microsoft-WNS/6.3 Host: 192.168.14.109:2089 Cache-Control: no-cache HeaderEnd: CRLF Sidenote: Notice how it's not even sending an accept header even though it only wants xml.

• SHAddToRecentDocs without a file?

  - by Chris Becke

  I was toying with an IRC client, integrating it with the windows 7 app bar. To get a "Frequent" or "Recent" items list one has to call SHAddToRecentDocs API. I want to add recent IRC channels visited to the Windows 7 Jumplist for the IRC application. Now, my problem is, IRC channels don't exist in the file system. And SHAddToRecentDocs seems to insist on getting some sort of file system object. Ive tried to work around it by creating a IShellItem pointing to my application, and giving it a command line to launch the channel. The shell is rebelling however, and thus far has not visibly added any of my "recent document" attempts to the Jumplist. Is there no way to do this without creating some kind of entirely unwanted filesystem object?

• How can I enable Vista/Win 7 theming/style for a ToolTip control?

  - by Joakim Hårsman

  In Windows Vista and Windows 7, ToolTips have a new visual style or theme, they are shiny grey metallic. How can I enable the new style for a ToolTip control? Some controls, like ListViews and ToolBars, use the new tooltips automatically, but other tooltips are rendered with the old yellow XP style. I've tried sending an TTM_SETWINDOWTHEME message but nothing happens and I'm not sure what string I am supposed to use for the visual style name. SetWindowTheme doesn't work either, I've used it successfully on ListViews and TreeViews to set the "Explorer" style (see http://www.danielmoth.com/Blog/TreeViewVista.aspx), but that doesn't seem to work on ToolTips. I'm using the plain win32 C API.

• Measuring Programmers' Productivity. Bad, good or invasive?

  - by Fraga

  A client needs my company to develop an app that will be able to measure the programmer productivity, by getting information from VS, IE, SSMS, profiler and VMware. For example: Lines, Methods, Classes (Added, Deleted, Modified) How many time spent in certain file, class, method, specific task, etc. How many time in different stages of the development cycle (Design, Coding, Debugging, Compiling, Testing) Real lines of code. Etc They told me they want to implement PSP. Would you resign if a company wants to measure this way? OR Would you install this kind of software for self improvement?

• Component properties working at designtime but not runtime

  - by delphi-rulez-2010

  I am creating a component that uses a collection and collection items of panels. I can't seem to get the colors to work at runtime, but yet they seem to work just fine at design time. You can download the component source code here: http://www.shaneholmes.net/pasfiles/ There is a Consoles (Tcollection) property, status colors property, and a Edit mode property Each console (TCollectionItem) has a status property when changed, the consoles property is changed based on the components StatusColors property. When the components EditMode property is set to true, you can move the panels around at runtime. Question: Why does the colors only work at designtime and not runtime. thanks

• Very long strings as primary keys in a database for caching

  - by Bill Zimmerman

  Hi, I am working on a web app that allows users to create dynamic PDF files based on what they enter into a form (it is not very structured data). The idea is that User 1 enters several words (arbitrary # of words, practically capped of course), for example: A B C D E There is no such string in the database, so I was thinking: Store this string as a primary key in a MySQL database (it could be maybe around 50-100k of text, but usually probably less than 200 words) Generate the PDF file, and create a link to it in the database When the next user requests A B C D E, then I can just serve the file instead of recreating it each time. (simple cache) The PDF is cpu intensive to generate, so I am trying to cache as much as I can... My questions are: Does anyone have any alternative ideas to my approach What will the database performance be like? Is there a better way to design the schema than using the input string as the primary key?

• Sending message from working non-gui thread to the main window

  - by bartek

  I'm using WinApi. Is SendMessage/PostMessage a good, thread safe method of communicating with the main window? Suppose, the working thread is creating a bitmap, that must be displayed on the screen. The working thread allocates a bitmap, sends a message with a pointer to this bitmap and waits until GUI thread processes it (for example using SendMessage). The working thread shares no data with other threads. Am I running into troubles with such design? Are there any other possibilities that do not introduce thread synchronizing, locking etc. ?
