  • Importing data from a text file using python

    - by Will
    I have a text file containing data in rows and columns (~17000 rows in total). Each column is a uniform number of characters long, with the 'unused' characters filled in by spaces. For example, the first column is 11 characters long, but the last four characters in that column are always spaces (so that it appears to be a nice column when viewed with a text editor). Sometimes it's more than four if the entry is less than 7 characters. The columns are not otherwise separated by commas, tabs, or spaces. They are also not all the same number of characters (the first two are 11, the next two are 8 and the last one is 5 - but again, some are spaces). What I want to do is import the entires (which are numbers) in the last two columns if the second column contains the string 'OW' somewhere in it. Any help would be greatly appreciated.

  • What's this UI pattern called?

    - by Bears will eat you
    I'm trying to figure out what this sort of thing is called, and eventually how I can create one in a web browser. It looks like this (screenshot of the first app that came to mind): The specific component/pattern I'm looking for is the two list boxes ("Included Gear" and "Excluded Gear") that represent inclusion/exclusion of items from a set. I'm not really looking for the WPF name (if there is one) but it might be helpful. I am looking for the name of this thingy, if there is one, and if you really want to make my day, you can point me toward a jQuery or YUI way of making one of these dealies in a browser. In case you were wondering, the screenshot is a World of Warcraft gear optimization program. Go figure why it was the first program that came to mind when I was trying to think of an example.

  • Class structure for the proposed data and its containers ?

    - by Prix
    First I would like to wish a happy new year to everyone that may read this :) I am having trouble on how to make a container for some data that I am importing into my application, and I am not sure on how to explain this very well and my english is not really a that good so I hope you can bear with my mistake and help me with some guidance. Currently with a foreach I am importing the follow fields from the data I receive: guid, itemid, name, owner(optional, can be null), zoneid, titleid, subid, heading, x, y, z, typeA, typeB, typeC From the above fields I need to store a Waypoint list of all coords a given item has moved to BUT for each guid I have a new list of waypoints. And from the waypoint list the first entry is also my initial item start location which would be my item initial position (if you notice i have a separate list for it which I was not sure would be better or not) not all items have a waypoint list but all items have the first position. So the first idea I came with to store this data was a list with a class with 2 inner classes with their list: public List<ItemList> myList = new List<ItemList>(); public class ItemList { public int guid { get; set; } public int itemid { get; set; } public string name { get; set; } public int titleid { get; set; } public itemType status { get; set; } public class Waypoint { public float posX { get; set; } public float posY { get; set; } public float posZ { get; set; } } public List<Waypoint> waypoint = new List<Waypoint>(); public class Location { public int zone { get; set; } public int subid { get; set; } public int heading { get; set; } public float posX { get; set; } public float posY { get; set; } public float posZ { get; set; } } public List<Location> position = new List<Location>(); } So here is an example of how I would add a new waypoint to a GUID that exists in the list bool itemExists = myList.Exists(item => item.guid == guid && item.itemid == itemid); if (itemExists) { int lastDistance = 3; ItemList.Waypoint nextWaypoint; ItemList myItem = myList.Find(item => item.guid == guid && item.itemid == itemid); if (myItem.waypoint.Count == 0) { nextWaypoint = new ItemList.Waypoint(); nextWaypoint.posX = PosX; nextWaypoint.posY = PosY; nextWaypoint.posZ = PosZ; } else { ItemList.Waypoint lastWaypoint = myItem.waypoint[myItem.waypoint.Count - 1]; if (lastWaypoint != null) { lastDistance = getDistance(x, y, z, lastWaypoint.posX, lastWaypoint.posY, lastWaypoint.posZ); } if (lastDistance > 2) { nextWaypoint = new ItemList.Waypoint(); nextWaypoint.posX = PosX; nextWaypoint.posY = PosY; nextWaypoint.posZ = PosZ; } } myItem.waypoint.Add(nextWaypoint); } Then to register a new item I would take advantage of the itemExist above so I won't register the same GUID again: ItemList newItem = new ItemList(); newItem.guid = guid; newItem.itemid = itemid; newItem.name = name; newItem.status = status; newItem.titleid = titleid; // Item location ItemList.Location itemLocation = new ItemList.Location(); itemLocation.subid = 0; itemLocation.zone= zone; itemLocation.heading = convertHeading(Heading); itemLocation.posX = PosX; itemLocation.posY = PosY; itemLocation.posZ = PosZ; newItem.position.Add(itemLocation); myList.Add(newItem); Could you help me with advices on how my class structure and lists should look like ? Are there better ways to interate with the lists to get lastWaypoint of a GUID or verify wether an item exist or not ? What else would you advise me in general ? PS: If you have any questions or if there is something I missed to post please let me know and I will update it.

  • How to prevent GUI blocking?

    - by Kovu
    Hi, I have a timer that ticks every 3 seconds. If the timer found something a messagebox will show. Then the timer should wait 30 seconds, before he show again the messagebox (the user of course must have time to react). How can I handle this? I tried a Thread.Sleep(30000), but the GUI blocks of course. My other Idea is a second timer that will be activated after the first ticks and reactivate the first timer in the tick-method. So: t1 tick - msg box - after click - t2 enable (30 sec tick) - t2 tick, enable t1 But I think thats not a good idea, is there a better way?

  • POST request is returning response success but is not posting the data

    - by Vineeth
    I am making a POST request to the MOXTRA API and it should return me the following response : { "data": { "id": user_id, //some user id "revision": 5, "name": "My First Binder", "created_time": 1402384947587, "updated_time": 1402384947587 }, "code": "RESPONSE_SUCCESS" } And I am making this POST request using Java Script var d = { 'name': 'My First Binder' }; var bind = JSON.stringify(d); $.post('https://api.moxtra.com/user_id/binders?access_token=' + access_token+ '&callback=?', bind, function(response) { alert( response.data.id); },'json'); }) But the alert that i get for alert(response.data.id) is "undefined" and the alert if i write alert(response.code) is "RESPONSE_SUCCESS" What is wrong with the above code , how am i getting a response success and getting undefined at the same time

  • Rails botches the SQL on a complex save

    - by Dan B
    Hi, I am doing something seemingly pretty easy, but Rails is messing up the SQL. I could just execute my own SQL, but the framework should be able to handle this. Here is the save I am trying to perform: w = WhipSenVote.find(:first, :conditions => ["whip_bill_id = ? AND whip_sen_id = ?", bill_id, k]) w.votes_no = w.votes_no - 1 w.save My generated SQL looks like this: SELECT * FROM "whip_sen_votes" WHERE (whip_bill_id = E'1' AND whip_sen_id = 7) LIMIT 1 And then: UPDATE "whip_sen_votes" SET "votes_yes" = 14, "updated_at" = '2009-11-13 19:55:54.807000' WHERE "id" = 15 The first select statement is correct, but as you can see, the Update SQL statement is pretty wrong, though the votes_yes value is correct. Any ideas? Thanks!

  • Generating Fibonacci series in F#

    - by photo_tom
    I'm just starting to learn F# using VS2010 and below is my first attempt at generating the Fibonacci series. What I'm trying to do is to build a list of all numbers less than 400. let fabList = let l = [1;2;] let mutable a = 1 let mutable b = 2 while l.Tail < 400 do let c = a + b l.Add(c) let a = b let b = c My first problem is that on the last statement, I'm getting an error message "Incomplete structured construct at or before this point in expression" on the last line. I don't understand what I'm doing wrong here. While this seems to be an obvious way to build the list in a fairly efficient way (from a c++/C# programmer), from what little I know of f#, this doesn't seem to feel to be the right way to do the program. Am I correct in this feeling?

  • render json data returned from mvc controller

    - by user1765862
    I'm having js function which calls mvc controller action method which return list of data as json. function FillCountryCities(countryId) { $.ajax({ type: 'GET', url: '/User/FillCityCombo', data: { countryId: countryId }, contentType: 'application/json', success: function (data) { alert(data[0].Name); } error: function () { alert('something bad happened'); } .... format of data which sent back from controller is Name (string) and Id (Guid) Now I just want to alert Name on success first item from collection. Double checked controller sends 20 records, so it should alert first from collection but I'm getting error something bad happened update: public JsonResult FillCityCombo(Guid countryId) { var cities = repository.GetData() .Where(x = x.Country.Id == countryId).ToList(); if (Request.IsAjaxRequest()) { return new JsonResult { Data = cities, JsonRequestBehavior = JsonRequestBehavior.AllowGet }; } else { return new JsonResult { Data = "Not Valid Request", JsonRequestBehavior = JsonRequestBehavior.AllowGet }; } }

  • Trying to use json to populate areas of my website using mysql, php, and jquery.

    - by RyanPitts
    Ok, so this is my first attempt at doing anything with JSON. I have done a lot with PHP and MySql as well as jQuery and JavaScript...but nothing with JSON. I have some data in a MySql database. In the codes below i am using a PHP file to retrieve the data from the MySql database and using json_encode to format it to JSON. This file is being called by the JavaScript that runs when the page loads (well, it runs on document.ready actually). I then use jQuery to access the JSON keys and values to fill in areas of the page "dynamically". Here is the code snippets i am using (excuse my "noobness" on writing these snippets, still learning all this). This is my script that is on my HTML page test.php: <script type="text/javascript"> $(document).ready(function(){ $.getJSON("json_events.php",function(data){ $.each(data.events, function(i,events){ var tblRow = "<tr>" +"<td>" + events.id + "</td>" +"<td>" + events.customerId + "</td>" +"<td>" + events.filingName + "</td>" +"<td>" + events.title + "</td>" +"<td>" + events.details + "</td>" +"<td>" + events.dateEvent + "</td>" +"<td><a href='assets/customers/testchurch/events/" + events.image + "'>" + events.image + "</a></td>" +"<td>" + events.dateStart + "</td>" +"<td>" + events.dateEnd + "</td>" +"</tr>" $(tblRow).appendTo("#eventsdata tbody"); }); }); $.getJSON("json_events.php",function(data){ $.each(data.events, function(i,events){ $("#title").html("First event title: " + events.title + " ..."); }); }); }); </script> This is the code for the php file being called by the above JS: json_events.php <?php require_once('includes/configread.php'); $arrayEvents = array(); $resultsEvents = mysql_query("SELECT * FROM events"); while($objectEvents = mysql_fetch_object($resultsEvents)) { $arrayEvents[] = $objectEvents; } $json_object_events = json_encode($arrayEvents); $json_events = "{\"events\": " . $json_object_events . " }"; echo $json_events; require_once('includes/closeconnread.php'); ?> This is my JSON that is held in the variable $json_events from my php file json_events.php: { "events": [ { "id": "2", "customerId": "1004", "filingName": "testchurch", "title": "Kenya 2011 Training Meeting", "details": "This meeting will be taking place on Sunday, February 10th @ 6pm. Get ready for our annual Kenya trip in 2011. We have been blessed to be able to take this trip for the past 3 years. Now, it's your turn to bless others! Come to this training meeting to learn how to minister to the people in Kenya and also learn what we'll be doing there.", "dateEvent": "2011-02-10", "image": "kenya2011.jpg", "dateStart": "2010-09-04", "dateEnd": "2011-02-10" }, { "id": "6", "customerId": "1004", "filingName": "testchurch", "title": "New Series: The Journey", "details": "We will be starting our new series titled "The Journey". Come worship with us as we walk with Paul on his 2nd missionary journey.", "dateEvent": "2011-01-02", "image": "", "dateStart": "2010-09-06", "dateEnd": "2011-01-02" } ] } This is my HTML on test.php: <table id="eventsdata" border="1"> <thead> <tr> <th>id</th> <th>customerId</th> <th>filingName</th> <th>title</th> <th>details</th> <th>dateEvent</th> <th>image</th> <th>dateStart</th> <th>dateEnd</th> </tr> </thead> <tbody></tbody> </table> <div id="title"></div> I have two questions really... Question 1: Does this code look like it is written correctly at first glance? Question 2: I want to be able to select only the title from the first event in the JSON array. The code i am using now is selecting the second events' title by default it seems. How can i accomplish this?

  • Coalesce and Case-When with To_Date not working as expected (Postgres bug?)

    - by ADTC
    I'm using Postgres 9.1. The following query does not work as expected. Coalesce should return the first non-null value. However, this query returns null (1?) instead of the date (2). select COALESCE( TO_DATE('','yyyymmdd'), --(1) TO_DATE('20130201','yyyymmdd') --(2) ); --(1) this evaluates independently to null --(2) this evaluates independently to the date, and therefore is the first non-null value What am I doing wrong? Any workaround? Edit: This may have nothing to do with Coalesce at all. I tried some experiments with Case When constructs; it turns out, Postgres has this big ugly bug where it treats TO_DATE('','yyyymmdd') as not null, even though selecting it returns null.

  • How do I split the output from mysqldump into smaller files?

    - by lindelof
    I need to move entire tables from one MySQL database to another. I don't have full access to the second one, only phpMyAdmin access. I can only upload (compressed) sql files smaller than 2MB. But the compressed output from a mysqldump of the first database's tables is larger than 10MB. Is there a way to split the output from mysqldump into smaller files? I cannot use split(1) since I cannot cat(1) the files back on the remote server. Or is there another solution I have missed? Edit The --extended-insert=FALSE option to mysqldump suggested by the first poster yields a .sql file that can then be split into importable files, provided that split(1) is called with a suitable --lines option. By trial and error I found that bzip2 compresses the .sql files by a factor of 20, so I needed to figure out how many lines of sql code correspond roughly to 40MB.

  • When iterating over values, why does typeof(value) return "string" when value is a number? Javascrip

    - by Mark
    I'm using Google Chrome for this test: Contrary to intuition, the first loop alerts "string" 3 times, while the second loop alerts "number" 3 times. numarray = [1, 2, 3]; //for-each loop for(num in numarray) alert(typeof(num)); //standard loop for(i=0; i<numarray.length; i++) alert(typeof(numarray[i])); I was expecting both loops to alert "number" 3 times. How is the first loop implemented in Javascript? In other words, if the for-each is syntactic sugar, what is its equivalent using a standard loop? Also, is there some way to iterate over an object's namespace using a standard loop? I'm looking to touch every one of some object's methods and attributes using a loop of the second kind. I'm new to Javascript and any help is highly appreciated, thanks.

Right now I'm displaying data from a dataset and the selection mode is FullRowSelect. Any way to set this? There are two scenarios to deal with: 1) Everytime the timer ticks the selected row always go to the first row of datagridview. 2) Once a row is clicked, it is selected but after the timer ticks the selected row goes to the first one. Thanks for your help! A newbie programmer

  • Add Words to Android's UserDictionary

    - by SaulBack
    I want to add an entire medical dictionary to my android (Moto Droid). I would like to be able to send text messages and have the medical words be in the predictable text. I've been trying to write a small app that would accomplish this, but everything I try the app crashes on startup. I've never written an app for a mobile platform so that is a first for me. Here is what is not working properly. public class WordAdd extends Activity { /** Called when the activity is first created. */ public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); UserDictionary.Words.addWord( this , "newMedicalWord", 1, UserDictionary.Words.LOCALE_TYPE_CURRENT); } } It seems so simple to do, yet I am so stuck. Thanks for any help you can provide.

  • Possible to exclude or reorder a column from `*` ?

    - by Earlz
    Is it possible to exclude a column from a select * from table statement with SQL Server? I have a need for this and this is my only option other than parsing a raw SQL string to get out the required field names (I really don't want to do that). Just to be bold. When the query is made I do not have access to the list of fields needed from the table but I do know which field I do not need. This is part of a complex multi-part query. Surely there must be some way even if it's "hackish" such as using table variables or views My other option is to reorder the columns. My problem is with ExecuteScalar SQL functions which get the first row and first column.

    I have some values on my tableview coming from database. I simply tap one of them, navigate to detailsView then I can see the title and description of that value on my navigation controller. (title on navigation bar, description on text view in detailsView) but when I wanted to search, I click search bar, keyboard comes up from the bottom, tableview minimizes a bit then find what I want from table. I tap again but titles and descriptions show very first value of my table view .. It does not show the correct title and description. Whenever I searched, it shows the title and description of very first value on my table view..

  • Conditional Counting in Mathematica

    - by 500
    Considering the following list : dalist = {{1, a, 1}, {2, s, 0}, {1, d, 0}, {2, f, 0}, {1, g, 1}} I would like to count the number of times a certain value in the first column takes a certain value in column 3. So in this example my desired output would be: {{1,1,2}, {1,0,1}, {2,1,0}, {2,0,2}} Where the latest sublist {2,0,2} being read as: When the value is 2 in the first column, a corresponding value (same row in matrices world) in column 3 of 0 is present twice. I hope this is not to confusing. I added the second Column to convey the fact that the columns are distant to each other. If possible, no reordering should happen. EDIT : {1,2,3,4,5} {1,0} are the exact values taken by the columns I am actually dealing with in my data. I know I am missing the correct description. Please edit if you can and know it. Thank you

  • Do I have to hash twice in C#?

    - by Joe H
    I have code like the following: class MyClass { string Name; int NewInfo; } List<MyClass> newInfo = .... // initialize list with some values Dictionary<string, int> myDict = .... // initialize dictionary with some values foreach(var item in newInfo) { if(myDict.ContainsKey(item.Name)) // 'A' I hash the first time here myDict[item.Name] += item.NewInfo // 'B' I hash the second (and third?) time here else myDict.Add(item.Name, item.NewInfo); } Is there any way to avoid doing two lookups in the Dictionary -- the first time to see if contains an entry, and the second time to update the value? There may even be two hash lookups on line 'B' -- one to get the int value and another to update it.

  • Thread Jobs in Java

    - by Bragaadeesh
    Hi, I want to spawn 200 threads simultaneously in Java. What I'm doing right now is running into a loop and creating 200 threads and starting them. After these 200 gets completed, I want to spawn another 200 set of threads and so on. The gist here is that the first 200 threads I spawned need to be FINISHED before spawning the next set. I tried the code below, but its not working for(int i=0;i<200;i++){ Thread myThread = new Thread(runnableInstance); myThread.start(); } for(int i=0;i<200;i++){ Thread myThread = new Thread(runnableInstance); myThread.start(); } Note: I have intentionally put the for loop Twice, but the desired effect I intend is not happening simply because the second for loop is executed before the first set of threads end their execution. Please advise

  • Making commercial Java software

    - by roddik
    Hi. I intend to make some software to be sold over internet. I've only created open-source before, so I have really no idea of how to protect it from being cracked and distributed as warez. Bearing in mind that I know like two programms that aren't either cracked or not really useful I decided that the only more or less reliable way may look like this: Connect to a server and provide licensing info and some sort of hardware summary info If everything is fine, the server returns some crucial missing parts of the program bound to that certain pc along with the usage limit of say 2 days That crucial stuff is not saved to hard drive, so it is downloaded every time the program starts, if the programm runs more than 2 days, data is downloaded again If the same info is used from different computers, suspend the customer account What do you think about this? It may seem a bit to restrictive, but I'd better make less sales at first then eventually see my precious killer app downloaded for free. Anyways, first I need some basic theory/tutorials/guides about how to ensure that user only uses a certain Java app if he has paid for it, so please suggest some. Thanks

  • Preinitialize BackgroundAudioPlayer in WP7?

    - by kgrevehagen
    When I am using the BackgroundAudioPlayer in my Windows Phone 7 application, it takes a lot of time to load the first time I want to play a song. Is there any way of preinitializing the BackgroundAudioPlayer before playing the first track, so that when I start playing, it starts right along? I have googled it, but no luck. I am just using BackgroundAudioPlayer.Instance when I e.g. want to play, pause, stop etc an audiotrack. Is there something other i could do to fix this? Thanks in advance!
