  • iOS Facebook Access Token To Get User Wall Feed (status)

    - by Felix
    [DISCLAIMER : None of the access token or ID below here are real] I've done research for three solid days and no result on how to get user wall feed(post). I have used https://graph.facebook.com/oauth/access_token?client_id=YOUR_APP_ID&client_secret=YOUR_APP_SECRET&grant_type=client_credentials and get the access token which is something like this access_token=454345994651138|bAMGfuW-ueNXGCahley7ga125HN and then https://graph.facebook.com/100005939123542/feed?access_token=454345994651138|bAMGfuW-ueNXGCahley7ga125HN It gives me general information such as user's likes, name, id, current city... but NOT user's wall posts. I've learned that there are three types of access token, which is App Token, User Token, and Page Token. In order to get user/feed by using graphAPI, I need to request to get User Token, but there's NO information in the lousy Facebook Doc! (Which frustrated me the most!) In order to generate the user access token, we need to set some permission, generate the access token, and GET the user's wall feed, which is in JSON format. My question is : How do I get the User Access Token in order to get user wall post in iOS Xcode?

  • Drawing graphs in MS Excel somehow got complicated

    - by Ivan
    I want to draw several graphs and combine them into one figure. I will explain the problem in an example. Let's say that I want to draw two graphs with these points: Graph #1 (X and Y are defining a coordinate). X - Y _____ 1 - 5 2 - 5 5 - 7 9 - 10 Graph #2 X - Y _____ 6 - 8 8 - 12 9 - 7 12 - 8 15 - 11 21 - 11 What I do is that I create a chart and click on "Select Data". There I create two series and choose X and Y values. However, this doesn't work since it doesn't allow me to choose different X values for different graphs. Although I choose different for these two series, the second one is chosen for both. This is how it looks like in the end: Do you know how to fix this? I'm using Excel 2008 for Mac.

  • Which C++ graphics library should I use?

    - by mspoerr
    Hello, I found the following graphics libraries, but I am not sure which one I should use. Maybe there are some more... Graphviz (http://www.graphviz.org/) Boost Graph Library (http://www.boost.org/doc/libs/1_42_0/libs/graph/doc/index.html) Lemon (http://lemon.cs.elte.hu/trac/lemon) igraph (http://igraph.sourceforge.net/introduction.html) What it should do: draw a undirected network map come as header only or static lib for Windows the output format should be user editable Graphviz is the only one I tried so far, but I found no static lib for it, I failed to build it by my own and the documentation could be better. Therefore I looked around and found these other three libs. I would be glad to get some recommendations which lib to choose. Thanks, /mspoerr

  • Set Facebook status using iphone app

    - by gmcalab
    I have just started with the new graph api for facebook. I have gotten a few items to work like logging in and getting the user name and displaying this to the screen. I am having trouble figuring out how to set my status with the graph api... I have tried a couple things but I always receive and error response back. Any ideas? NSMutableDictionary *params = [NSMutableDictionary dictionaryWithObjectsAndKeys: @"test2", @"test", nil]; [_facebook requestWithMethodName:@"status.set" andParams:params andHttpMethod:@"POST" andDelegate:self];

  • Finding contained bordered regions from Excel imports.

    - by dmaruca
    I am importing massive amounts of data from Excel that have various table layouts. I have good enough table detection routines and merge cell handling, but I am running into a problem when it comes to dealing with borders. Namely performance. The bordered regions in some of these files have meaning. Data Setup: I am importing directly from Office Open XML using VB6 and MSXML. The data is parsed from the XML into a dictionary of cell data. This wonks wonderfully and is just as fast as using docmd.transferspreadsheet in Access, but returns much better results. Each cell contains a pointer to a style element which contains a pointer to a border element that defines the visibility and weight of each border (this is how the data is structured inside OpenXML, also). Challenge: What I'm trying to do is find every region that is enclosed inside borders, and create a list of cells that are inside that region. What I have done: I initially created a BFS(breadth first search) fill routine to find these areas. This works wonderfully and fast for "normal" sized spreadsheets, but gets way too slow for imports into the thousands of rows. One problem is that a border in Excel could be stored in the cell you are checking or the opposing border in the adjacent cell. That's ok, I can consolidate that data on import to reduce the number of checks needed. One thing I thought about doing is to create a separate graph that outlines the cells using the borders as my edges and using a graph algorithm to find regions that way, but I'm having trouble figuring out how to implement the algorithm. I've used Dijkstra in the past and thought I could do similar with this. So I can span out using no endpoint to search the entire graph, and if I encounter a closed node I know that I just found an enclosed region, but how can I know if the route I've found is the optimal one? I guess I could flag that to run a separate check for the found closed node to the previous node ignoring that one edge. This could work, but wouldn't be much better performance wise on dense graphs. Can anyone else suggest a better method? Thanks for taking the time to read this.

  • Can't get Facebook's user photos with php

    - by Liso22
    I'm trying to get the user photos, but I cannot get the user's photos data. I'm trying this: $photos = $facebook->api('https://graph.facebook.com/'.$profileFID.'/photos?access_token='.$access_token); print_r($photos); I'm sure the URL is correct since pasting it in the browser shows the photos array. However when I try to print the array to check if I got it I get only this: ( [id] => https://graph.facebook.com/1409006586/photos ) How can I get the full array with the user photos?

  • facebook api getting full posts with > 2 comments or > 4 likes

    - by ejang
    when I make the user/feed request on the Facebook Open Graph API, I get a feed object where posts with 2 comments or 4 likes don't reveal the detailed information for those specific comments. I am using https://github.com/Thuzi/facebook-node-sdk to make requests but it is very similar to the 'request' NodeJS library. I can get the full posts individually by making a separate request for that post's Open Graph ID, but this doesn't lend itself to fun code because requests are asynchronous and nesting more asynchronous calls within asynchronous calls doesn't lend itself to fun code. Any way I can obtain the full posts?

  • How to hash and check for equality of objects with circular references

    - by mfya
    I have a cyclic graph-like structure that is represented by Node objects. A Node is either a scalar value (leaf) or a list of n=1 Nodes (inner node). Because of the possible circular references, I cannot simply use a recursive HashCode() function, that combines the HashCode() of all child nodes: It would end up in an infinite recursion. While the HashCode() part seems at least to be doable by flagging and ignoring already visited nodes, I'm having some troubles to think of a working and efficient algorithm for Equals(). To my surprise I did not find any useful information about this, but I'm sure many smart people have thought about good ways to solve these problems...right? Example (python): A = [ 1, 2, None ]; A[2] = A B = [ 1, 2, None ]; B[2] = B A is equal to B, because it represents exactly the same graph. BTW. This question is not targeted to any specific language, but implementing hashCode() and equals() for the described Node object in Java would be a good practical example.

  • Facebook access token: server-side vs client-side flows

    - by alexey
    Facebook docs: Facebook Platform supports two different OAuth 2.0 flows for user login: server-side (known as the authentication code flow in the specification) and client-side (known as the implicit flow). The server-side flow is used whenever you need to call the Graph API from your web server. The client-side flow is used when you need to make calls to the Graph API from a client, such as JavaScript running in a Web browser or from a native mobile or desktop app. What is the difference between access tokens taken by these flows? It seems like they length differ. Can we use server-side flow token on a client? And otherwise, can we use client-side flow token on a server?

  • How to executing the following command in Android?

    - by Aung Pyae
    I would like to create a new App Linking object for the sharing posts of my android application to facebook sdk. I look around and I found this. My App is "Mobile-Only". So, it seems I supposed to send this command to facebook. How can I send this ? FYI; I have set-up Facebook App and successfully integrated "Sharing Post on Facebook via Android App". Seems I am quite new on Graph API of Facebook SDK. Thanks. curl https://graph.facebook.com/app/app_link_hosts \ -F access_token="APP_ACCESS_TOKEN" \ -F name="Android App Link Object Example" \ -F android=' [ { "url" : "sharesample://story/1234", "package" : "com.facebook.samples.sharesample", "app_name" : "ShareSample", }, ]' \ -F web=' { "should_fallback" : false, }'

  • pchart pie chart legend and graph not correlating

    - by madphp
    Hi, I have ten values in the dataset, numbers 1 - 10 and corresponding values. Some of the values are coming back as zero, so they are not added to the chart, BUT, the legend is still listing 1 - 10. Because theres values missing in the chart, the colour coding is knocked off. ie Item 1, has a value of zero, its passed over in the chart, the colour in the legend is red, Item 2, has a value of 4, the percentage is calculated, and the chart gives it the colour red which is the colour for item 1 in the legend. Hope that makes sense. How can I print the legend just for the values that are displayed in the chart? --Mark

  • place and show pixel in the Cartesian plane graph in JavaFX

    - by user3671803
    I have this method to draw the Cartesian plane in JavaFX, using canvas and would like to know if it is possible to place or show the pixel: public class Grafics extends StackPane { private Canvas canvas; public void Grafics(){ GridPane grid = new GridPane(); grid.setPadding(new Insets(5)); grid.setHgap(10); grid.setVgap(10); canvas = new Canvas(); canvas.setHeight(500); canvas.setWidth(700); GridPane.setHalignment(canvas, HPos.CENTER); grid.add(canvas, 0, 2); GraphicsContext gc = canvas.getGraphicsContext2D(); gc.setFill(Color.BLACK); gc.fillRect(0, 0, canvas.getWidth(), canvas.getHeight()); gc.setFill(Color.WHITE); gc.fillRect(1, 1, canvas.getWidth() - 2, canvas.getHeight() - 2); drawAxesXY(gc); //call the method drawAxes getChildren().addAll(grid);// add an gridpane in stackpane } private void drawAxesXY(GraphicsContext gc1) { PixelWriter pixelWriter = canvas.getGraphicsContext2D().getPixelWriter(); gc1.setFill(Color.WHITE); gc1.setStroke(Color.BLACK); gc1.setLineWidth(1.5); gc1.strokeText("Y", 350, 30); gc1.scale(1, 1); gc1.translate((canvas.getHeight() / 50) - (canvas.getWidth() / 10), canvas.getHeight() / 50); gc1.strokeLine(canvas.getWidth() - 300, canvas.getWidth() - 300, canvas.getHeight() - 100, canvas.getHeight() / 30); pixelWriter.setColor(300, 300, Color.RED); gc1.strokeText("X", 620, 220); gc1.translate(canvas.getWidth() - (canvas.getHeight() / 10), -220); gc1.rotate(90.0); gc1.setFill(Color.WHITE); gc1.setStroke(Color.RED); gc1.setLineWidth(1.5); gc1.strokeLine(canvas.getWidth() - 250, canvas.getWidth() - 250, canvas.getHeight() - 50, canvas.getHeight() / 30); pixelWriter.setColor(620, 220, Color.RED); } } I put a line black and the other red http://postimg.org/image/tewjhco4z/ and I wanna know if is possible to place or show the pixel in Figure like this http://postimg.org/image/98k9mvnb3/

  • RIA Services for transmitting non DB object-graph

    - by Mike Gates
    I have been getting into RIA services because I thought it would simplify dealing with the services layer of web applications I wish to build. I see lots of examples out there showing how to create DomainService classes which expose and consume entities that have some kind of relational database backing, and therefore have foreign-key relationships. However, I would like to know how to expose and consume normal object graphs...objects that contain references to eachother but don't have foreign keys. For example, say I want a service operation called "GetFolderInformation(string pathToFolder)". I want this to return a custom object called "FolderInformation" structured with: - string Name - IEnumerable<FileInformation> Files I cannot get this to work because it seems that RIA wants to deal with entities that have foreign key relationships. Why? Why can't the serializer just see my object references and recreate that in the proxy on the other side? Data exists behind service layers that doesn't necessarily have foreign key relationships...like folder/file for example. EDIT: I realized I hadn't asked my question! My question is, is there a way to do what I am trying to do?

  • Y-value on bar graph in gnuplot?

    Can I get gnuplot to display the exact y-value or height of a data point (plotted using "with boxes") over its bar? I would like the plot to be easy to read so nobody has to line up the top of a bar with the y-axis and guess what the value is.

  • Uploading a picture to a album using the graph api

    - by kielie
    Hi guys, I am trying to upload an image to a album, but it's not working, here is the code I am using, $uid = $facebook->getUser(); $args = array('message' => $uid); $file_path = "http://www.site.com/path/to/file.jpg"; $album_id = '1234'; $args['name'] = '@' . realpath($file_path); $data = $facebook->api('/'. $album_id . '/photos', 'post', $args); print_r($data); This code is in a function.php file that gets called when a user clicks on a button inside of a flash file that is embedded on my canvas, so basically what I want it to do is, when the flash takes a screen shot and passes the variable "image" to the function, it should upload $_GET['image'] to the album. How could I go about doing this? Thanx in advance!

  • Data Flow Object Graph and An Execution Engine for it

    - by M Dotnet
    I would like to build a custom workflow engine from scratch. The input to this workflow is a data flow diagram which is composed of a series of activities connected together through lines where each each represent the data flow. Each activity can export multiple outputs. Activities are complex math functions but the logic is hidden from the user. My workflow engine job is to execute the given data flow diagram. Each activity within the data flow diagram is a custom activity and each activity can output different outputs. How do you suggest to model the data flow diagram object? I need to be able to construct the data flow diagram problematically (no need for drag and drop) but I need to display the final result graphically (for display and debugging purposes). Are there any libraries out there that I could use? Should I keep the workflow presentable as an xml? I know that there are many projects out there trying to essentially doing similar thing by building such workflow engines but I need something light weight and open source. I do not need any state machine execution engine and mine is primarily sequential workflow with fork and join capabilities. My activities are wrappable as basic C# classes and I do NOT want to use anything as heavy as .NET workflow foundation.
