  • Best canvas for drawing in wxPython?

    - by Pablo Rodriguez
    I have to draw a graph of elements composing a topological model of a physical network. There would be nodes and arches, and the latter could be unidirectional or bidirectional. I would like to capture the clicking events for the nodes and the arches (to select the element and show its properties somewhere), and the dragging events for the nodes (to move them around) and arches (to connect or disconnect elements). I've done some research and I've narrowed the alternatives down to OGL (Object Graphics Library) and FloatCanvas. I would not like to go down to the DrawingContext, but it is not discarded if necessary. Which canvas option would you choose?

  • Registry key editing vb6 startup

    - by Francesco D.
    Is it possible that someone here could explain how to use this code. Please keep in mind i am a complete amateur, so simplifications may be needed. Private Const cPGM = "C:\VB Forum\startup\Example.exe" Dim oShell As IWshShell_Class Set oShell = New IWshShell_Class oShell.RegWrite "HKLM\Software\Microsoft\Windows\CurrentVersion\Run\MyVBApp", _ cPGM, "REG_SZ" How exactly is this code used? Is it saved as an .exe file and ran or what? Thanks for your prompt reply and informational feedback.

  • Logging out of Facebook invalidates offline_access token

    - by Mike Pateras
    I'm getting an offline access token like this: https://graph.facebook.com/oauth/access_token?scope=offline_access&client_id=MYCLIENTID&redirect_uri=MYREDIRECTURI&client_secret=MYSECRET&code=MYCODE obviously the MYCLIENTID and stuff have been changed for the sake of this post. Anyway, as soon as the user logs out of facebook, the key seems to no longer be valid. Am I not requesting offline_access properly (there's still an "expires" value on it, should there be if it is actually getting offline access), or is that just how it works? If it's the latter, how can I get a key that will persist, regardless of if the user logs out of facebook? I'm sure this is possible, because Tweetdeck can still write to Facebook, even though I'm currently logged out.

  • C Question: How to store data inside the executable file

    - by michael
    Hello all, complete newbie here, I need to find a way to store 250 KB of plain text numbers inside my program's executable file. Usually, I would put the data in a separate file and let the program read it while it is running, but that's not an option here. Instead, the program and the data need to be in one executable file. I have absolutely no idea how to do it (except writing 250.000 #defines :-) and I'd appreciate any suggestions. Thank you very much!

  • JQuery Animate.

    - by Oliver
    Hi Really easy, I'm sure... I have a div which is the full screen and I want it to slide down from the top to the bottom. I have this: $('#full-screen').animate({ "bottom":0, height: 'toggle' }, 1000, function() { // Animation complete. }); But this is the wrong way round as the bottom moves up; how do I get the bottom to stay where is is and the top to slide down to meet it? Thanks

  • How to manually build mysql cache

    - by hamstar
    I have a table of over 150,000 rows of which most would be updated daily. I have mysql caching turned on so the pages load faster however everytime the database is updated the pages load slow again, which I assume is the cache building itself again. So at the moment I have resorted to doing a wget -m --delete-after http://localhost/ on the server however this takes about 4 hours to complete and moves something like 13 gig. Is there a better way to do this?

  • aacplus frame alignment problems

    - by Daniel Mošmondor
    I have an application that rips aac+ audio streams, cutting them at every regular interval (i.e. 10 minutes). Sometimes files are playable OK, but sometimes, Windows Media Player just closes when trying to build DirectShow graph. I am using Orban aacplus plugin, and it works under directshow. When I play this file with winamp or vlc, that have it's own aacplus decoding engine, it works fine. However, I need it to work under directshow. Anyway, problematic file is here: http://www.videophill.com/files/00272-20100418100002.aac I know that there is frame alignment error and I confirmed my theory by filling first 256 bytes with 0x00, tried to play it again, and it worked. Is there any info on aacplus frames available on the web, so I can try to find the beginning of the frame manually and cut the rest off?

  • Breaking change October: Status waiting when create custom audience with add user data file?

    - by THACH LN
    In my system, I create a custom audience - data file - mobile advertiser ids with 10k user. After I created it, I refreshed API link to get information about the audience which I've just created: https://graph.facebook.com/act_xxx/customaudiences?fields=id,account_id,name,lookalike_spec,retention_days,subtype,approximate_count,rule,delivery_status,operation_status,data_source,permission_for_actions&limit=500&access_token=xxx. (After breaking change in October 2014, status field not return. So I see operation_status) I see that: "operation_status": { "code": 410, "description": "No file has been uploaded for this audience, or the previous upload has failed due to system error. Please try uploading the file again." } But after about 10s, I refresh again, and operation_status change to: "operation_status": { "code": 200, "description": "Normal" } My quetions is: how to check this audience's status is waiting ( uploading file) , like when I create on facebook not my our system. Thanks for all anwser.

  • How can I run an external program from C and parse its output?

    - by Josh Matthews
    I've got a utility that outputs a list of files required by a game. How can I run that utility within a C program and grab its output so I can act on it within the same program? UPDATE: Good call on the lack of information. The utility spits out a series of strings, and this is supposed to be complete portable across Mac/Windows/Linux. Please note, I'm looking for a programmatic way to execute the utility and retain its output (which goes to stdout).

  • SQL Server 2008 - Query takes forever to finish even though work is actually done

    - by Brian
    Running the following simple query in SSMS: UPDATE tblEntityAddress SET strPostCode= REPLACE(strPostCode,' ','') The update to the data (at least in memory) is complete in under a minute. I verified this by performing another query with transaction isolation level read uncommitted. The update query, however, continues to run for another 30 minutes. What is the issue here? Is this caused by a delay to write to disk? TIA

    - by Sjuul Janssen
    I was reading Code Complete 2 and it mentions this: Many version-control tools wil insert version information into a file.

  • How to implement a C# interface in F#?

    - by Anton Andreev
    I would like to implement the following C# interface in F#: using System; using System.Collections.Generic; using System.Linq; using System.Text; using Mono.Addins; [TypeExtensionPoint] public interface ISparqlCommand { string Name { get; } object Run(Dictionary<string, string> NamespacesDictionary, org.openrdf.repository.Repository repository, params object[] argsRest); } This is what I have tried, but it gives me: "Incomplete structured construct at or before this point in expression" #light module Module1 open System open System.Collections.Generic; type MyClass() = interface ISparqlCommand with member this.Name = "Finding the path between two tops in the Graph" member this.Run(NamespacesDictionary, repository, argsRest) = new System.Object What am I doing wrong? Maybe indentation is wrong?

  • Global variables in hadoop.

    - by Deepak Konidena
    Hi, My program follows a iterative map/reduce approach. And it needs to stop if certain conditions are met. Is there anyway i can set a global variable that can be distributed across all map/reduce tasks and check if the global variable reaches the condition for completion. Something like this. While(Condition != true){ Configuration conf = getConf(); Job job = new Job(conf, "Dijkstra Graph Search"); job.setJarByClass(GraphSearch.class); job.setMapperClass(DijkstraMap.class); job.setReducerClass(DijkstraReduce.class); job.setOutputKeyClass(IntWritable.class); job.setOutputValueClass(Text.class); } Where condition is a global variable that is modified during/after each map/reduce execution.

  • emacs setup for web development

    - by fig-gnuton
    What should a complete emacs setup have if you want to use it for web development? This SO question is about using emacs for Rails, however it mostly leaves out things like HTML, CSS, and JavaScript. This emacs wiki page has suggestions for emulating aspects of TextMate, but isn't specific to web development.

  • Issuing multiple requests using HTTP/1.1 Pipelining

    - by Robert S. Barnes
    When using HTTP/1.1 Pipelining what does the standard say about issuing multiple requests without waiting for each request to complete? What do servers do in practice? I ask because I once tried writing a client which would issue a batch of GET requests for multiple files and remember getting errors. I wasn't sure if it was due to me incorrectly issuing the GET's or needing to wait for each individual request to finish before issuing the next GET.

  • parsing through html with php

    - by salmane
    while working on facebook connect I have to retrieve an access token from a url ( it is not in the url itself but in the file lined to that url) so this is what I do $url = "https://graph.facebook.com/oauth/access_token?client_id=".$facebook_app_id."&redirect_uri=http://www.example.com/facebook/oauth/&client_secret=".$facebook_secret."&code=".$code;" function get_string_between($string, $start, $end){ $string = " ".$string; $ini = strpos($string,$start); if ($ini == 0) return ""; $ini += strlen($start); $len = strpos($string,$end,$ini) - $ini; return substr($string,$ini,$len); } $access_token = get_string_between(file_get_contents($url), "access_token=", "&expires="); it looks ugly and clumsy is there a better way to do it ? thank you .

  • Obtain all keys of a Neo4j index

    - by MattiSG
    I have a Neo4j database whose content is generated dynamically from a big dataset. All “entry points” nodes are indexed on a named index (IndexManager.forNodes(…)). I can therefore look up a particular “entry point” node. However, I would now like to enumerate all those specific nodes, but I can't know on which key they were indexed. Is there any way to enumerate all keys of a Neo4j Index? If not, what would be the best way to store those keys, a data type that is eminently non-graph-oriented? UPDATE (thanks for asking details :) ): the list would be more than 2 million entries. The main use case would be to never update it after an initialization step, but other use cases might need it, so it has to be somewhat scalable. Also, I would really prefer avoiding killing my current resilience abilities, so storing all keys at once, as opposed to adding them incrementally, would be a last-resort solution.

  • How do I get an Iterator over a vector of objects from a Template?

    - by nieldw
    I'm busy implementing a Graph ADT in C++. I have templates for the Edges and the Vertices. At each Vertex I have a vector containing pointers to the Edges that are incident to it. Now I'm trying to get an iterator over those edges. These are the lines of code: vector<Edge<edgeDecor, vertexDecor, dir>*> edges = this->incidentEdges(); vector<Edge<edgeDecor, vertexDecor, dir>*>::const_iterator i; for (i = edges.begin(); i != edges.end(); ++i) { However, the compiler won't accept the middle line. I'm pretty new to C++. Am I missing something? Why can't I declare an iterator over objects from the Edge template? The compiler isn't giving any useful feedback. Much thanks niel

  • android spectrum analysis of streaming input

    - by TheBeeKeeper
    for a school project I am trying to make an android application that, once started, will perform a spectrum analysis of live audio received from the microphone or a bluetooth headset. I know I should be using FFT, and have been looking at moonblink's open source audio analyzer ( http://code.google.com/p/moonblink/wiki/Audalyzer ) but am not familiar with android development, and his code is turning out to be too difficult for me to work with. So I suppose my questions are, are there any easier java based, or open source android apps that do spectrum analysis I can reference? Or is there any helpful information that can be given, such as; steps that need be taken to get the microphone input, put it into an fft algorithm, then display a graph of frequency and pitch over time from its output? Any help would be appreciated, thanks.
