  • Facebook API returning wrong unread thread count

    - by houbysoft
    I'm trying to query the thread FQL table to get all unread messages, and also the count of unread items in the thread. This is how I query the table: SELECT thread_id,updated_time,snippet,snippet_author,unread FROM thread WHERE folder_id=0 AND unread!=0 From reading the doc to which I linked above, it seems to me that unread should include the count of unread messages in the thread. However, I just tested the above call and Facebook gives me back a value of unread=1, despite the thread in question having 4 unread items. This is how the thread looks on facebook.com (notice the (4), showing that unread should be 4): This is what the API returns to me, which is wrong (notice the "unread":1): { "data":[ { "name":"messages", "fql_result_set":[ { "thread_id":"BLAH BLAH BLAH", "updated_time":1333317140, "snippet":"BLAH BLAH BLAH", "snippet_author":BLAH, "unread":1 } ] } ] } Am I doing something wrong, or is this a bug?

  • What are some C++ Standard Library usage best practices?

    - by apphacker
    I'm learning C++ and the book I'm reading (The C++ Programming Language) says to not reinvent the wheel, to rely on the standard libraries. In C, I often end up creating a linked list, and link list iteration over and over again (maybe I'm doing that wrong not sure), so the ideas of containers available in C++, and strings, and algorithms really appeal to me. However I have read a little online, and heard some criticisms from my friends and coworkers about STL, so I thought I maybe I'd pick some brains here. What are some best practices for using STL, and what lessons have you learned about STL?

  • Problem understanding treesort in Haskell

    - by Jerry
    I am trying to figure out how exactly does treesort from here work (I understand flatten, insert and foldr). I suppose what's being done in treesort is applying insert for each element on the list thus generating a tree and then flattening it. The only problem I can't overcome here is where the list (that is the argument of the function) is hiding (because it is not written anywhere as an argument except for the function type declaration). One more thing: since dot operator is function composition, why is it an error when I change: treesort = flatten . foldr insert Leaf to treesort = flatten( foldr insert Leaf )?

  • want to change background of table td on hover

    - by Brad
    I have a webpage that displays a calendar, and I want to change the background-color of any td that has their day number linked, so when I hover over that day, it changes the background-color. I thought this would work: .main-calendar td { width:14%; height:100px; text-align:center; border:1px solid #000; font-size:20px; vertical-align:middle; display:block; } table.main-calendar td a:hover, table.main-calendar td a:visited { display:block; text-decoration:none; background-color:red; color:#fff; } table.main-calendar td a:link { display:block; text-decoration:none; background-color:green; color:#fff; } Any help is appreciated.

  • Is java.util.Scanner that slow?

    - by Cristian Vrabie
    Hi guys, In a Android application I want to use Scanner class to read a list of floats from a text file (it's a list of vertex coordinates for OpenGL). Exact code is: Scanner in = new Scanner(new BufferedInputStream(getAssets().open("vertexes.off"))); final float[] vertexes = new float[nrVertexes]; for(int i=0;i<nrVertexFloats;i++){ vertexes[i] = in.nextFloat(); } It seems however that this is incredibly slow (it took 30 minutes to read 10,000 floats!) - as tested on the 2.1 emulator. What's going on? I don't remember Scanner to be that slow when I used it on the PC (truth be told I never read more than 100 values before). Or is it something else, like reading from an asset input stream? Thanks for the help!

  • Refresh a control on the master page after postback

    - by Andreas
    Hi all! What i am trying to do here is to show a couple of validation messages in form of a bulletlist, so i have a Div on my master page containing a asp:bulletlist. Like this: <div> <asp:BulletedList ID="blstValidationErrorMessage" runat="server" BulletStyle="Disc"> </asp:BulletedList> </div> When i then click the Save button from any of my pages (inside the main contentPlaceHolder) i create a list of messages and give this list as datasouce like this: blstValidationErrorMessage.DataSource = validationMessageCollection; blstValidationErrorMessage.DataBind(); The save button is located inside an updatepanel: asp:UpdatePanel runat="server" ID="UpdatePanel" ChildrenAsTriggers="true" UpdateMode="Conditional" Nothing happens, i can see that the datasource of the bulletlist contains X items, the problems must arise because the Save button is inside an update panel and the elements outside this updatepanel (master page controls for example) is not refreshed. So my question is, how do i make the bulletlist refresh after the postback? Thanks in advance.

  • Browser back button broken between hidden div's

    - by Linda
    First of all, these pages will never be on the web but will be in internal memory. They are a group of linked documents---an ebook. http://www.anmldr.com/testdivs When I click on the link in the first div, the second div becomes visible and the first div is hidden. The problem is with the browser's back button. If you then click on the back button, the URL updates but the first div does not show again. How can I correct the back button so that the first div shows? The link from the second div to the first div works fine but it is the browser back button that I do not know how to work with. Thanks, Linda P.S. These are using CSS3 so it is better to use a WebKit based browser.

  • How can one put together multiple arrays into one string?

    - by Noor
    I'm having a hard time describing what I'm looking for. If we pretend that we're pulling an array (I've used the .split to get user input data) where each line represents a link. How can I then add an anchor tagg to that link that I'm pulling? I need to be able to put < a href=" + thearray + "anything< /a. The reason for this is that I'm dynamically creating a list. I think that if I create two variables, one with this part < a href=" one with the closing and then call some sort of function that puts those two and the pulled array in between them until the list is complete. Does this make any sense?

  • Django filter with two constraints on related model

    - by BJ Homer
    I have a django app with models as follows: A Question model An Answer model, with a ForeignKey back to the Question. (A question can have multiple answers.) A Flag model, with a ForeignKey to the Answer. (An answer can be flagged as inappropriate.) All of the above also have a user field, defining the user that created that object. I'm trying to get a list of all Questions with answers from the current user which have been flagged. I tried this: Question.objects.filter(answer__user=user).\ filter(answer__flag__isnull=True).distinct() … but I believe that will return a list of Questions with answers from the current user and with answers which have been flagged, but will not necessarily guarantee that it is the user's answer that has been flagged. Is there an easy way to do this? Basically, I want to make the answer part of the filter refer to the same answer on both of them. Please let me know if something is unclear.

  • .NET values lookup

    - by Maciej
    Hi, I have a feeling of missing something obvious. UDP receiver application. It holds a collection of valid UDP sender IPs - only guys with IP on that list will be considered. Since that list must be looked at on every packet and UDPs are so volatile, that operation must be maximum fast. Good choice is Dictionary but it is a key-value structure and what I actually need here is a dictionary-like (hash lookup) key only structure. Is there something like that? Small annoyance rather than a bug but still. I can still use Dictionary Thanks, M.

  • is there a way to get a "subtree" from hclust ? (R)

    - by Tal Galili
    Hello all, I wish to create a "subtree" from an hclust object. For example, let's say I have the following object: a <- list() # initialize empty object a$merge <- matrix(c(-1, -2, -3, -4, 1, 2, -5,-6, 3,4), nc=2, byrow=TRUE ) a$height <- c(1, 1.5, 3,4,4.5) # define merge heights a$order <- 1:6 # order of leaves(trivial if hand-entered) a$labels <- 1:6# LETTERS[1:4] # labels of leaves class(a) <- "hclust" # make it an hclust object plot(a) # look at the result Now I wish the extract from it the following subtree: a <- list() # initialize empty object a$merge <- matrix(c(-1, -2, -3, -4, 1, 2 ), nc=2, byrow=TRUE ) a$height <- c(1, 1.5, 3) # define merge heights a$order <- 1:4 # order of leaves(trivial if hand-entered) a$labels <- 1:4# LETTERS[1:4] # labels of leaves class(a) <- "hclust" # make it an hclust object plot(a) # look at the result How could I access it? (I know that cutree could get me the objects of the sub tree, but not create an actual hclust object) Thanks for any help, Tal

  • Plugin architecture in .net: unloading

    - by henchman
    Hello everybody, I need to implement a plugin architecture within c#/.net in order to load custom user defined actions data type handling code for a custom data grid / conversion / ... from non-static linked assembly files. Because the application has to handle many custom user defined actions, Iam in need for unloading them once executed in order to reduce memory usage. I found several good articles about plugin architectures, eg: ExtensionManager PluginArchitecture ... but none of them gave me enough sausage for properly unloading an assembly. As the program is to be distributed and the user defined actions are (as the name states) user defined: how to i prevent the assembly from executing malicious code (eg. closing my progra, deleting files)? Are there any other pitfalls one of you has encountered?

  • Why does C# not implement GetHashCode for Collections?

    - by Peterdk
    I am porting something from Java to C#. In Java the hashcode of a ArrayList depends on the items in it. In C# I always get the same hashcode from a List... Why is this? For some of my objects the hashcode needs to be different because the objects in their list property make the objects non-equal. I would expect that a hashcode is always unique for the object's state and only equals another hashcode when the object is equal. Am I wrong?

  • Why this doesn't work: [MySQL][ODBC 5.1 Driver]Access denied for user

    - by bvandrunen
    So I know that there is a very similar question to this all over the web as well as stack overflow: http://stackoverflow.com/questions/2539961/error-access-denied-for-user-mysql-server but my question I think is different. So I have set up a linked server and it works...I have the correct permissions set up for my IP's that I am using. However the problem arises when our user "webuser@correctIP" tries to access it. Therefore, any user using window authentication is allowed to access it and works great...but any that are not using windows authentication are blocked. However, I have tried all the common solutions such as setting up a strict password, changing security settings in Microsoft SQL Server etc. Nothing is working. Any help is appreciated. Thanks. FYI: I am using this from Microsoft SQL Server 2008 - mysql (through myphpadmin)

  • Rails - Ability to Enable/Disable Links on a View?

    - by AnApprentice
    Hello, I have a UserMailer View that has several link_to's like so: <%= link_to('XXXXXXXX Link Title', item_url(@item, :only_path => false), :style => 'color:#5196E3;text-decoration:underline;') %> The page has several different links. I'd like to know if there is a way to globally set in the view to enable or disable the links. If enabled, the above would run like normal, if not the block above would just show the text (XXXXXXXX Link Title) and not be linked? Any ideas other than wrapping every link_to inside a IF statement? Thanks

  • What are Android different screens dimensions in dp for different screens (e.g. xlarge = 960dp x 720dp)?

    - by Zizo
    in this link: Range of screens supported, Android team mentioned that: As you design your UI for different screen sizes, you'll discover that each design requires a minimum amount of space. So, each generalized screen size above has an associated minimum resolution that's defined by the system. These minimum sizes are in "dp" units—the same units you should use when defining your layouts—which allows the system to avoid worrying about changes in screen density. xlarge screens are at least 960dp x 720dp large screens are at least 640dp x 480dp normal screens are at least 470dp x 320dp small screens are at least 426dp x 320dp So, If I want to support all Android screens, can I create images, for full screen view, in those dimensions and that will be sufficient condition to support all available screens? or they are just the minimum sizes, and I need other dimensions? If other dimensions are needed, Please list them as in the list above. Thanks in Advance.

  • Why does addSubview load the view asynchronously

    - by moshe
    I have a UIView that I want to load when the user clicks a button. There happens to be some data processing that happens as well after I call addSubview that involves parsing an XML file retrieved from the web. The problem is the view doesn't show up until after the data processing even if addSuview is called first. I think I'm missing something here, can anyone help? Code: I have a "Loading..." view I'm adding as a custom modal (meaning I'm not using the modalViewController). This action is linked to a button in the navigationController. - (IBAction)parseXml:(id)sender { LoadingModalViewController *loadingModal = [[LoadingModalViewController alloc] initWithNibName:@"LoadingModalViewController" bundle:nil]; [navigationController.view addSubview:loadingModal.view]; [xmlParser parse]; }

  • [Django] How to find out whether a model's column is a foreign key?

    - by codethief
    I'm dynamically storing information in the database depending on the request: // table, id and column are provided by the request table_obj = getattr(models, table) record = table_obj.objects.get(pk=id) setattr(record, column, request.POST['value']) The problem is that request.POST['value'] sometimes contains a foreign record's primary key (i.e. an integer) whereas Django expects the column's value to be an object of type ForeignModel: Cannot assign "u'122'": "ModelA.b" must be a "ModelB" instance. Now, is there an elegant way to dynamically check whether b is a column containing foreign keys and what model these keys are linked to? (So that I can load the foreign record by it's primary key and assign it to ModelA?) Or doesn't Django provide information like this to the programmer so I really have to get my hands dirty and use isinstance() on the foreign-key column?

  • Enumerating all combinations of lists of different types

    - by jball
    Given two IEnumberables of different types, what is the best practice (considering readability and maintainability) for iterating over both lists to perform an action on all possible combinations? My initial solution was to use nested foreach loops, iterating over the first IEnumerable, and then within that loop, iterating over the second IEnumerable and passing the value from the outer and the current loop into the target method. Eg.: enum ParamOne { First, Second, Etc } List<int> paramTwo = new List<int>() { 1, 2, 3 }; void LoopExample() { foreach (ParamOne alpha in Enum.GetValues(typeof(ParamOne))) { foreach (int beta in paramTwo) { DoSomething(alpha, beta); } } } I tried to restructure it with LINQ, but ended up with something that had no obvious advantages and seemed less intuitive. A search here shows lots of questions about nesting foreachs to iterate over child properties, but I couldn't find anything about iterating over two distinct lists.

  • Calculating probability that a string has been randomized? - Python

    - by RadiantHex
    Hi folks, this is correlated to a question I asked earlier (question) I have a list of manually created strings such as: lucy87 gordan_king fancy_unicorn77 joplucky_kanga90 base_belong_to_narwhals and a list of randomized strings: johnkdf pancake90kgjd fancy_jagookfk manhattanljg What gives away that the last set of strings are randomized is that sequences such as 'kjg', 'jgf', 'lkd', ... . Any clever way I could separate strings that contain these apparently randomized strings from the crowd? I guess that this plays a lot on the fact that certain characters are more likely to be placed next to others (e.g. 'co', 'ka', 'ja', ...). Any ideas on this one? Kylotan mentioned Reverend, but I am not sure if it can be used fr such purpose. Help would be much appreciated!

  • Excel VBA: can delete validation but not add new one

    - by user1882965
    My code is as follows If Cells(Target.Row, 2) = "" And (Cells(Target.Row, 3) = "" Or Cells(Target.Row, 3) = "") Then Sheets("MySheet").Activate Cells(Target.Row, 3).Activate ActiveCell.Validation.Delete If (Cells(Target.Row, 2) = "Type A") Then ActiveCell.Validation.Add Type:=xlValidateList, AlertStyle:=xlValidAlertStop, Operator:=xlBetween, Formula1:="=AvailableVersions" ElseIf (Cells(Target.Row, 2) = "Type B") Then ActiveCell.Validation.Delete Else ActiveCell.Validation.Add Type:=xlValidateWholeNumber, AlertStyle:=xlValidAlertInformation, Formula1:="0", Formula2:="9999999" End If End If So the issue I am having comes whenever I reach ActiveCell.Validation.Add Run Time Error '1004': Application-defined or object-defined error Not a very helpful error, and also this occurs with both number and list validation type, so I am sure it is not an issue with the list itself which has workbook level scope anyway. It never occurs on ActiveCell.Validation.Delete which I find weird? I have been all over google trying to find a solution, and most suggest that it is caused by running dynamic validation code from a button which hogs focus despite the Activate call, but I am running on sheet change event rather than on button press so I don't think this is my issue - any ideas? I've wasted basically a whole day on this! :(
