  • How can I use offline access with the Facebook javascript SDK?

    - by Tony
    In the Facebook javascript api there is a login function in which you specify extended permissions: http://developers.facebook.com/docs/reference/javascript/FB.login One of these permissions is offline access. So I can save the facebook user's session key and assume it will not expire for a long time. The question I have is simple - how do I use the session key? I understand that the session key will last longer, but I don't understand how to use it in the Facebook API. For one of my products, a user must restart his/her browser and I would like to recognize them when they restart. The problem is that they are logged out of facebook, so they must login on my site again where I would rather just use offline access. Sample code would be great! Thanks

  • Can I get a PTypeInfo from a string?

    - by Mason Wheeler
    This is probably going to be a "no", but is there any way I can use Delphi's RTTI, either old-school or the 2010 extended RTTI, to pass in a string containing the name of a type, specifically the name of an enumerated type, and have it give me the PTypeInfo for that type? I've looked through RTTI.pas and TypInfo.pas and I don't see any function that would do that, but I might have missed something. What I'm looking for: var info: PTypeInfo; begin info := GetTypeInfoFromName('TComponentStyle'); end; Or something like that. Thing is, the name of the enumerated type would be passed in; it wouldn't be known at compile time.

  • itemdoubleclick event in ExtJS Charts

    - by Abdel Olakara
    Hi all, I got a strange issue today while working on ExtJS charts. I am trying to use some of the events for the chart when user clicks on the chart items. I found the following events are available: itemclick, itemdoubleclick, itemdrag, itemdragstart, itemdragend, itemmouseover, itemmouseout Here is my test chart where I have implemented all these events. Each event just create a list tag in my debuging console. The issue is, no matter what, itemdoubleclick do not get fired! what is the issue? Why is it not getting fired? xtype:'columnchart', width:600, height:350, id:'myChart', store: store, xField: 'month', yField: 'sales', listeners: { itemdoubleclick: function(o) { var dh = Ext.DomHelper; dh.append('consoleList', {tag: 'li', html: 'itemdoubleclick'}); } } In firebug console, I see that this event is registered. PS: In my code above, I have put only the event that is not working. Thanks in advance for your ideas and suggestions.

  • Validate Unicode String and Escape if Unicode is Invalid (C/C++)

    - by vy32
    I have a program that reads arbitrary data from a file system and outputs results in Unicode. The problem I am having is that sometimes filenames are valid Unicode and sometimes they aren't. So I want a function that can validate a string (in C or C++) and tell me if it is a valid UTF-8 encoding. If it is not, I want to have the invalid characters escaped so that it will be a valid UTF-8 encoding. This is different than escaping for XML --- I need to do that also. But first I need to be sure that the Unicode is right. I've seen some code from which I could hack this, but I would rather use some working code if it exists.

  • Why Is my json-object from AJAX not understood by javascript, even with 'json' dataType?

    - by pete
    My js code simply gets a json object from my server, but I think it should be automatically parsed and turned into an object with properties, yet it's not allowing access properly. $.ajax({ type: 'POST', url: '/misc/json-sample.js', data: {href: path}, // THIS IS THE POST DATA THAT IS PASSED IN TO THE DRUPAL MENU CALL TO GET THE MENU... dataType: 'json', success: function (datax) { if (datax.debug) { alert('Debug data: ' + datax.debug); } else { alert('No debug data: ' + datax.toSource() ) ; } The /misc/json-sample.js file is: [ { "path": "examplemodule/parent1/child1/grandchild1", "title": "First grandchild option", "children": false } ] (I have also been trying to return that object from drupal as follows, and the same results.) Drupal version of misc/json-sample.js: $items[] = array( 'path' = 'examplemodule/parent1/child1/grandchild1', 'title' = t('First grandchild option'), 'debug' = t('debug me!'), 'children' = FALSE ); print drupal_to_js($items); What happens (in FF, which has the toSource() capability) is the alert with 'No debug data: [ { "path": "examplemodule/parent1/child1/grandchild1", "title": "First grandchild option", "children": false } ] Thanks

  • How to return radio checked object with jQuery ?

    - by Kim
    HTML <input type="radio" name="rdName" id="uniqueID1" value="1" checked="checked"> <input type="radio" name="rdName" id="uniqueID2" value="2"> <input type="radio" name="rdName" id="uniqueID3" value="3"> jQuery #1 $('input:radio[name=rdName]:checked').val(); jQuery #2 $('input[name=rdName]:checked'); jQuery #1 gets the value of checked radio, but I need to get the whole object to get the ID. jQuery #2 get this (from Chrome Dev console). Object "0" is the actual object I need, but I am unable to just that. 0: HTMLInputElement constructor: function Object() context: HTMLDocument length: 1 prevObject: Object selector: input[name=rdName]:checked __proto__: Object Any ideas how to isolate the needed object ?

  • How do I display a field's hidden characters in the result of a query in Oracle?

    - by Chris Williams
    I have two rows that have a varchar column that are different according to a Java .equals(). I can't easily change or debug the Java code that's running against this particular database but I do have access to do queries directly against the database using SQLDeveloper. The fields look the same to me (they are street addresses with two lines separated by some new line or carriage feed/new line combo). Is there a way to see all of the hidden characters as the result of a query?I'd like to avoid having to use the ascii() function with substr() on each of the rows to figure out which hidden character is different. I'd also accept some query that shows me which character is the first difference between the two fields.

  • What is the scope of require_once in PHP?

    - by TMG
    Simple question: Is the scope of require_once global? For example: <?PHP require_once('baz.php'); // do some stuff foo ($bar); function foo($bar) { require_once('baz.php'); // do different stuff } ?> When foo is called, does it re-parse baz.php? Or does it rely on the already required file from the main php file (analagous to calling require_once twice consecutively for the same include file)? I saw this thread before, but it didn't quite answer the question: http://stackoverflow.com/questions/1669707/should-require-once-some-file-php-appear-anywhere-but-the-top-of-the-file Thanks for your help!

  • Flex - How do I use a variable to define the name of an instantiated object

    - by flexfanatic
    Essentially this is what I want to accomplish, however it doesn't work like this. Is there any solution: - The problem is I can't dynamically name a new object... ??? pulling my hair out. import views.printingView; public function initComponent(o:Array):void{ SomeObject::Array = o; for(i=0; i <=SomeObject.length-1; i++){ 'invoice'+{SomeObject[i].namedID}:printingView = new printingView(); someDisplayContainer.addChild('invoice'+{SomeObject[i].namedID}); 'invoice'+{SomeObject.namedID}.publicInitFunction(SomeObject[i]); } }

  • Deferring signal handling in Linux

    - by EpsilonVector
    I'm trying to figure out how to block a signal in Linux kernel 2.4 (user space) from invoking its handler, but keep it available to be handled later, preferably as soon as I re activate the handling of said signal. The function sigprocmask seem to come up in all my search results, but I can't find a good, clear description that explains whether the blocked signal gets "saved" to be handled later, and if so where and how do I handle it when I'm ready for it. Can someone please clarify what's going on, preferably with a code example? Thanks in advance.

  • Garbage collection when compiling to C

    - by Jules
    What are the techniques of garbage collection when compiling a garbage collected language to C? I know of two: maintain a shadow stack that saves all roots explicitly in a data structure use a conservative garbage collector like Boehm's The first technique is slow, because you have to maintain the shadow stack. Potentially every time a function is called, you need to save the local variables in a data structure. The second technique is also slow, and inherently does not reclaim all garbage because of using a conservative garbage collector. My question is: what is the state of the art of garbage collection when compiling to C. Note that I do not mean a convenient way to do garbage collection when programming in C (this is the goal of Boehm's garbage collector), just a way to do garbage collection when compiling to C.

  • What is your favourite JavaScript reference manual?

    - by daniel.sedlacek
    Hi, I come from strong typed unambiguous OOP background and I struggle to find JavaScript reference manual that would fit my needs. The ideal one should be: compendious and handy, I'm not looking for ECMA standart reference. type specific, even if JS is not strong typed function arguments and returns have a type. browser specific, no matter the standards every browser is different and this ambiguity is killing me. examples, they are always handy. off line, this would be fine but it's not a condition. What is your favourite one? Help me, Obi-Wan Kenobi; you're my only hope!

  • Is there a way to change the maximum width of a window without using the WM_GETMINMAXINFO message?

    - by David
    I want to change the imposed Windows maximum width that a window can be resized to, for an external application's window (not my C#/WinForms program's window). The documentation of GetSystemMetrics for SM_CXMAXTRACK says: "The default maximum width of a window that has a caption and sizing borders, in pixels. This metric refers to the entire desktop. The user cannot drag the window frame to a size larger than these dimensions. A window can override this value by processing the WM_GETMINMAXINFO message." Is there a way to modify this SM_CXMAXTRACK value (either system wide or for one particular window), without processing the WM_GETMINMAXINFO message? Maybe an undocumented function, a registry setting, etc.? (Or: The documentation for MINMAXINFO.ptMaxTrackSize says: "This value is based on the size of the virtual screen and can be obtained programmatically from the system metrics SM_CXMAXTRACK and SM_CYMAXTRACK." Maybe there is a way to change the size of the virtual screen?) Thank you

  • JQuery .submit() changes post data

    - by ajbeaven
    I'm posting a form with javascript and it seems to be changing a value that I've entered in. Html: <% using (Html.BeginForm("ChangeTime", "Cart", new { cartItemId = cartItem.CartItemID }, FormMethod.Post, null)) { %> <%= Html.TextBox("startTime")%> <input type="submit" value="Update" /> <% } %> JQuery: <script type="text/javascript"> $('#startTime').change(function() { $(this).parent('form').submit(); }); </script> When I put a time in the textbox (05/05/2010 06:08 am), the form is submitted, however the string as it comes through, is 05/05/2010 - with the time part removed. I see this in fiddler. If get rid of the javascript and click the button above, it goes through how it should. Why is JQuery changing my text?

  • Bulkloading schema less entities on Google App Engine

    - by Rahul
    The new bulkloader added into SDK 1.3.4 works great for models that have a schema. For models inheriting db.Expando (or loosely defined schemas) i would like to understand what i would have to do to bulk upload them. I defined a custom connector, that implemented the ConnectorInterface and converted my data to the python dict required. How can i use this dict to define entities that get uploaded to the data store ? In the documentation there seems to be a post_import_function that can be used to return the entities that get uploaded. Is there an example on how this function is used ?

  • Linux, how to capture screen, and simulate mouse movements.

    - by 2di
    Hi All I need to capture screen (as print screen) in the way so I can access pixel color data, to do some image recognition, after that I will need to generate mouse events on the screen such as left click, drag and drop (moving mouse while button is pressed, and then release it). Once its done, image will be deleted. Note: I need to capture whole screen everything that user can see, and I need to simulate clicks outside window of my program (if it makes any difference) Spec: Linux ubuntu Language: C++ Performance is not very important,"print screen" function will be executed once every ~10 sec. Duration of the process can be up to 24 hours so method needs to be stable and memory leaks free (as usuall :) I was able to do in windows with win GDI and some windows events, but I'ev no idea how to do it in Linux. Thanks a lot

  • sampling integers uniformly efficiently in python using numpy/scipy

    - by user248237
    I have a problem where depending on the result of a random coin flip, I have to sample a random starting position from a string. If the sampling of this random position is uniform over the string, I thought of two approaches to do it: one using multinomial from numpy.random, the other using the simple randint function of Python standard lib. I tested this as follows: from numpy import * from numpy.random import multinomial from random import randint import time def use_multinomial(length, num_points): probs = ones(length)/float(length) for n in range(num_points): result = multinomial(1, probs) def use_rand(length, num_points): for n in range(num_points): rand(1, length) def main(): length = 1700 num_points = 50000 t1 = time.time() use_multinomial(length, num_points) t2 = time.time() print "Multinomial took: %s seconds" %(t2 - t1) t1 = time.time() use_rand(length, num_points) t2 = time.time() print "Rand took: %s seconds" %(t2 - t1) if __name__ == '__main__': main() The output is: Multinomial took: 6.58072400093 seconds Rand took: 2.35189199448 seconds it seems like randint is faster, but it still seems very slow to me. Is there a vectorized way to get this to be much faster, using numpy or scipy? thanks.

  • Custom http service responds fine to local IP address but NOT to localhost or 127.0.0.1

    - by Scrappydog
    I'm trying to connect to a custom http service written by another developer. The service responds fine on a local IP address and port number. Such as: http://10.1.1.1:1234 but it does NOT respond to http://localhost:1234 or http://127.0.0.1:1234 The service is a simple single function application written in VC++ that takes an http post string and returns another string. I'm trying to all it from C# using HttpWebRequest.GetResponse, but I can reproduce the same problem manually from a web browser... Test environment is Windows 2008 Server. Bottom line I'm looking for some troubleshooting tips to help the other developer fix his code.

  • Can't resolve CalledFromWrongThreadException with Handler

    - by michel
    I will try to keep it simple: In my main activity I make a handler: public class ARViewer extends ARDisplayActivity { public final MHandler mHandler = new MHandler(this); public void onCreate(Bundle savedInstanceState) { ... The class MHandler: public final class MHandler extends Handler{ //main activity private ARViewer arnv; public MHandler(ARViewer arnv){ this.arnv = arnv; } @Override public void handleMessage(Message msg) { ... case H_RR : arnv.setContentView(R.layout.routeplanner); break; ... super.handleMessage(msg); } } But if I call the handleMessage method from a callback function in a other Class, definitely from a other thread, I still get the exception message: CalledFromWrongThreadException (Only the original thread that created a view hierarchy can touch its views) : public void rFound(Route route) { Message msg = new Message(); msg.what = MHandler.H_RR; ARViewer.arnv.mHandler.handleMessage(msg); }

  • Good coding style to do case-select in XSLT

    - by Scud
    I want to have a page display A,B,C,D depending on the return value from XML value (1,2,3,4). My approaches are by javascript or XSLT:choose. I want to know which way is better, and why? Can I do this case-select in .cs code (good or bad)? Should I javascript code in XSLT? Can the community please advise? Thanks. Below are the code.

  • How to add multiple files to py2app?

    - by Niek de Klein
    I have a python script which makes a GUI. When a button 'Run' is pressed in this GUI it runs a function from an imported package (which I made) like this from predictmiP import predictor class MiPFrame(wx.Frame): [...] def runmiP(self, event): predictor.runPrediction(self.uploadProtInterestField.GetValue(), self.uploadAllProteinsField.GetValue(), self.uploadPfamTextField.GetValue(), \ self.edit_eval_all.Value, self.edit_eval_small.Value, self.saveOutputField) When I run the GUI directly from python it all works well and the program writes an output file. However, when I make it into an app, the GUI starts but when I press the button nothing happens. predictmiP does get included in build/bdist.macosx-10.3-fat/python2.7-standalone/app/collect/, like all the other imports I'm using (although it is empty, but that's the same as all the other imports I have). How can I get multiple python files, or an imported package to work with py2app?

  • Maximum Possible File Name Length in Windows Kernel

    - by Lambert
    I was wondering, what is the longest possible name length allowed by the Windows kernel? E.g.: I know the kernel uses UNICODE_STRING structures to hold all object paths, and since the byte length of a wide-character string is stored inside a USHORT, that allows for a maximum path length of 2^15 - 1 characters. Is there a similar, hard restriction on a file name (rather than path)? (I don't care if NTFS or FAT32 imposes a particular restriction; I'm looking for the longest possible theoretically allowed name in the kernel, assuming no additional file system or shell restrictions.) (Edit: For those wondering why this even matters, consider that normally, traversing a directory is achieved by FindFirstFile/FindNextFile calls, one call per file. Given the function named NtQueryDirectoryFile, which is the underlying system call and which returns multiple file names per call, it's actually possible to take advantage of this maximum-length restriction on the path to make an extremely-fast directory traverser that uses solely the stack as a buffer. Now I'm trying to extend that concept, and I need to know the maximum size of a file name.)
