  • how to return multiple array items using json/jquery

    - by Scarface
    Hey guys, quick question, I have a query that will usually return multiple results from a database, while I know how to return one result, I am not sure how to return multiple in jquery. I just want to take each of the returned results and run them through my prepare function. I have been trying to use 'for' to handle the array of data but I don't think it can work since I am returning different array values. If anyone has any suggestions, I would really appreciate it. JQUERY RETRIEVAL for(i=0; i < json.rows; i++) { $('#users_online').append(online_users(json[i])); $('#online_list-' + count2).fadeIn(1500); } PHP PROCESSING $qryuserscount1="SELECT active_users.username,COUNT(scrusersonline.id) AS rows FROM scrusersonline LEFT JOIN active_users ON scrusersonline.id=active_users.id WHERE topic_id='$topic_id'"; $userscount1=mysql_query($qryuserscount1); while ($row = mysql_fetch_array($userscount1)) { $onlineuser= $row['username']; $rows=$row['rows']; if ($username==$onlineuser){ $str2= "<a href=\"statistics.php?user=$onlineuser\"><div class=\"me\">$onlineuser</div></a>"; } else { $str2= "<b><a href=\"statistics.php?user=$onlineuser\"><div class=\"others\">$onlineuser</div></a></b>"; } $data['rows']=$rows; $data['entry']=$str1.$str2; }

  • Subsonic 3, SimpleRepository, SQL Server: How to find rows with a null field?

    - by desautelsj
    How ca I use Subsonic's Find<T> method to search for rows with a field containing the "null" value. For the sake of the discussion, let's assume I have a c# class called "Visit" which contains a nullable DateTime field called "SynchronizedOn" and also let's assume that the Subsonic migration has created the corresponding "Visits" table and the "SynchronizedOn" field. If I was to write the SQL query myself, I would write something like: SELECT * FROM Visits WHERE SynchronizedOn IS NULL When I use the following code: var visits = myRepository.Find<Visit>(x => x.SynchronizedOn == null); Subsonic turns it into the following SQL query: SELECT * FROM Visits WHERE SynchronizedOn == null which never returns any rows. I tried the following code but it throws an error: visits = repository.Find<Visit>(x => x.SynchronizedOn.HasValue); I was able to use the following syntax: var query = from v in repository.All<Visit>() where v.SynchronizedOn == null orderby v.CreatedOn select v; visits = query.ToList<Visit>(); but it's not as nice an short as using the Find<T> method. Anyone knows how I can specify the "SynchronizedOn IS NULL" condition in the Find<T> method?

  • managed beans as managed properties

    - by Sean
    I am using JSF 1.1 on WebSphere 6.1. I am building search functionality within an application and am having some issues. I've stripped out the extras, and have left myself with the following: 4 managed beans: SearchController - Controller bean, session scope SearchResults - session scope (store the results) ProductSearch - session scope (store the search conditions) ResultsBacking - Backing bean for DataTable, used to determine which row was clicked, request scope The SearchController bean has, as managed properties, the other 3. All except ResultsBacking are session scoped. If there is only 1 item in the search results, I want to bring up that record directly. I call setFirst(0) for the data table in the ResultsBacking method (I want to use the existing method that handle which item was clicked, so this is called right after the setFirst). When I go to do another search, I get an IllegalArgumentException when calling getRowData in the data table. According to the api, this is thrown 'if now(sic) row data is available at the currently specified row index'. I'm confused as to why this happens. It works the first time but not the second. Do I need to remove the ResultsBacking on a new search to get rid of the old state?

  • REST application, Transactions, Cache drop

    - by Julian Davchev
    Hi, I am building REST API in php with memcache layer on top for caching all resources. After some reading experience it turns out it's best when documents are as simple as posible...mainly due to dropping cache sequences. So if there is 'building','room' entities for the 'room' document I would only place the id of the 'building' and not the whole data of it. Then on api client side I would merge data as needed. Problem becomes when I need to update/insert (most cases more than one table). I update one resource but on second update system fails or whatever and there becomes database inconsistancies. I see several solutions: 1. Implement rest transactions which I find wrong and complex as idea is to be stateless and easy. 2. On update/insert actions I pass more complex data (not single entities) so I can force transactions on API level. But this will make it weird that your GET document structure is same as PUT document structure. And again somehow make drop sequences complex. Any pointers are more than welcome. Cheers,

  • python / sqlite - database locked despite large timeouts

    - by Chris Phillips
    Hi, I'm sure I'm missing something pretty obvious, but I can't for the life of me stop my pysqlite scripts crashing out with a database is locked error. I have two scripts, one to load data into the database, and one to read data out, but both will frequently, and instantly, crash depending on what the other is doing with the database at any given time. I've got the timeout on both scripts set to 30 seconds: cx = sqlite.connect("database.sql", timeout=30.0) and think I can see some evidence of the timeouts in that i get what appears to be a timing stamp (e.g 0.12343827e-06 0.1 - and how do I stop that being printed?) dumped occasionally in the middle of my curses formatted output screen, but no delay that ever gets remotely near the 30 second timeout, but still one of the other keeps crashing again and again from this. I'm running RHEL5.4 on a 64 bit 4 cpu HS21 IBM blade, and have heard some mention about issues about multi-threading and am not sure if this might be relevant. Packages in use are sqlite-3.3.6-5 and python-sqlite-1.1.7-1.2.1, and upgrading to newer versions outside of RedHat's official provisions is not a great option for me. Possible, but not desirable due to the environment in general. I have had autocommit=1 on previously on both scripts, but have since disabled on both, and am now cx.commit()ing on the inserting script and not committing on the select script. Ultimately as I only ever have one script actually making any modifications, I don't really see why this locking should ever ever happen. I have noticed that this is significantly worse over time when the database has gotten larger. It was recently at 13mb with 3 equal sized tables, which was about 1 day's worth of data. creating a new file has significantly improved this, which seems understandable, but the timeout ultimately just doesn't seem to be being obeyed. Any pointers very much appreciated. Thanks Chris

  • How to get all active parameters in ASP.NET MVC (2)

    - by SztupY
    Hi! I was wondering whether there is a way to create an ActionLink or similar, that changes only a few parameters of the actual query, and keeps all the other parameters intact. For example if I'm on an URL like http://example.com/Posts/Index?Page=5&OrderBy=Name&OrderDesc=True I want to change only the Page, or OrderBy parameter and keep all other parameters the same, even those I don't yet know of (like when I want to add a Search parameter or something similar too). The header of my current action looks like this: public ActionResult Index(int? Page, string OrderBy, bool? Desc) and I'm only interested in the values that this controller "eats". I want however that when I extend this action (for example with a string Search parameter) the links should work the same way as before. Here is what I did already: Create a new RouteValueDictionary and fill it with everything from RouteData.Values Problem: This only fills the parameters that are used in the Routing, so all other optional parameters (like Page) to the controller are lost Add everything from HttpContext.Request.QueryString to the previous dictionary This is what I am currently using Problem: It might have some junk stuff, that the Controller didn`t ask for, and it doesn't work if the page was loaded using POST. You also don't have any ModelBindings (but this isn't much of a problem, because we are re-sending everything anyway) Use HttpContext.Request.Params Problem: this has too much junk data which imho one shouldn't add to a RouteValueDictionary that is passed to an ActionLink So the questions: Is there an RVD that has all the data that was passed to the Controller and was used by it? Is this solution good, or are there any caveats I didn't think about (mainly in the context of changing a few query parameters while keeping the others intact)? Is there a way to filter out the "junk" data from the Params object?

  • How to pass multiple parameter in DomainService - WCF

    - by S.Amani
    Hi, Let's say I have a window which should submit 3 model in client side (Silverlight Client Application). My problem is each time I submit the form, data on the server side which I passed them from client are empty. I've used nested class which contains my models, instead of passing multiple object as parameter, but it didn't work again. My Personnel Data Transfer Object Code is something like this : [DataContract] public class PersonnelDTO : EntityObject { [Key] [DataMember] public int PersonnelId { get; set; } [Include] [DataMember] [Association("Personnel_ID", "PersonnelId", "Personnel_ID")] public Personnel Personnel { get; set; } [Include] [DataMember] [Association("Personnel_Info_ID", "PersonnelId", "Personnel_Info_ID")] public Personnel_Info PersonnelInfo { get; set; } } I fill up this model to pass data from client to server (DomainService). and also my domain service code is : [Invoke] public void AddPersonnel(PersonnelDTO personnelDTO) { // Model are EMPTY in DTO ObjectContext.AddToPersonnels(personnelDTO.Personnel); ObjectContext.AddToPersonnel_Info(personnelDTO.PersonnelInfo); ObjectContext.SaveChanges(); } I don't know if there is a way to pass multiple parameter in WCF Service method include Generic List. Any advice will be graceful. Thanks.

  • XML String into a DataGridView (C#)

    I am currently working with a webservice to pull a report about users in a remote support system.

  • How to Verify Signature, Loading PUBLIC KEY From PEM file?

    - by bbirtle
    I'm posting this in the hope it saves somebody else the hours I lost on this really stupid problem involving converting formats of public keys. If anybody sees a simpler solution or a problem, please let me know! The eCommerce system I'm using sends me some data along with a signature. They also give me their public key in .pem format. The .pem file looks like this: -----BEGIN PUBLIC KEY----- MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQDe+hkicNP7ROHUssGNtHwiT2Ew HFrSk/qwrcq8v5metRtTTFPE/nmzSkRnTs3GMpi57rBdxBBJW5W9cpNyGUh0jNXc VrOSClpD5Ri2hER/GcNrxVRP7RlWOqB1C03q4QYmwjHZ+zlM4OUhCCAtSWflB4wC Ka1g88CjFwRw/PB9kwIDAQAB -----END PUBLIC KEY----- Here's the magic code to turn the above into an "RSACryptoServiceProvider" which is capable of verifying the signature. Uses the BouncyCastle library, since .NET apparently (and appallingly cannot do it without some major headaches involving certificate files): RSACryptoServiceProvider thingee; using (var reader = File.OpenText(@"c:\pemfile.pem")) { var x = new PemReader(reader); var y = (RsaKeyParameters)x.ReadObject(); thingee = (RSACryptoServiceProvider)RSACryptoServiceProvider.Create(); var pa = new RSAParameters(); pa.Modulus = y.Modulus.ToByteArray(); pa.Exponent = y.Exponent.ToByteArray(); thingee.ImportParameters(pa); } And then the code to actually verify the signature: var signature = ... //reads from the packet sent by the eCommerce system var data = ... //reads from the packet sent by the eCommerce system var sha = new SHA1CryptoServiceProvider(); byte[] hash = sha.ComputeHash(Encoding.ASCII.GetBytes(data)); byte[] bSignature = Convert.FromBase64String(signature); ///Verify signature, FINALLY: var hasValidSig = thingee.VerifyHash(hash, CryptoConfig.MapNameToOID("SHA1"), bSignature);

  • Access to multiple ItemRenderers within an AdvancedDataGrid

    - by user310340
    I've create an AdvancedDataGrid where most of the cell are based on an ItemRenderer. The custom ItemRenderer (SoundBox) extends VBox. This custom component allow for simple changes in the background color based on user clicking on a cell. Here is the snippet of the AdvancedDataGrid (nothing too advanced): <mx:AdvancedDataGrid id="fsfw" dataProvider="{fsfWordList}" sortableColumns="false" > <mx:groupedColumns> <mx:AdvancedDataGridColumn width="35" dataField="wordcount" headerText=" "/> <mx:AdvancedDataGridColumn id="myWord" width="150" headerText="TEST ITEMS"> <mx:itemRenderer> <mx:Component> <components:SoundBox width="100%" letterSound="{data.word}" /> </mx:Component> </mx:itemRenderer> </mx:AdvancedDataGridColumn> <mx:AdvancedDataGridColumn width="200" headerText="Correct / 2 points" dataField="sound1"> <mx:itemRenderer> <mx:Component> <components:SoundBox width="100%" letterSound="{data.sound1}" pointColumn="2"/> </mx:Component> </mx:itemRenderer> </mx:AdvancedDataGridColumn> </mx:groupedColumns> </AdvancedDataGrid> What I'm trying to do is change the background color of (let's just say I have one row of data) row1, cell1 to green when the user clicks on cell3 of row1. I'm unsure as to how I get access to those items (ItemRenderer/SoundBox) within the Grid. Any Ideas? THX!

  • Link Maven OSGi to Maven NetBeans Platform Project

    - by mxro
    I am using NetBeans 6.9 Beta and I would like to accomplish the following: Set up a project representing the main application using Maven (for instance "Maven Project", "Maven NetBeans Application") Ideally, the project should only contain the necessary libraries to run in Apache Felix (I would like to be able to right-click the project and select "Run in Felix") I do not want that the project contains all the NetBean Platform APIs I would prefer to implement the modules using OSGi. For instance "Maven OSGi Bundle", "Maven NetBeans Module" + OSGi These are the problems, which I have at the moment: The standard Maven archetype ("Maven NetBeans Application") seems always to select all APIs and I have not found a way to deselect APIs - in normal NetBeans Platform Applications that can be accomplished by going to the project properties and deselected the platform modules) - I guess it has something to do with the NetBeans repository (http://bits.netbeans.org/maven2)? Do I have to create another repository? When creating normal "NetBeans Module" with OSGi support, the modules contain both NetBeans Module and OSGi meta data, which is nice. But the "Maven NetBeans Modules" have only NetBeans meta data and the Maven OSGi Bundles have only OSGi meta data). I figured out how to add modules to the project by using project / new and then placing the modules in the Maven project folder. However, I do not quite know yet how I could link to modules from other locations (NetBeans uses Maven modules, which have to be in the same directory as the project?). Below some useful links for Maven + OSGi in NetBeans wiki.netbeans.org/STS_69_Maven_OSGI NetBeans Maven OSGi Test Specification platform.netbeans.org/tutorials/nbm-maven-quickstart.html NetBeans Platform Quick Start Using Maven (6.9) wiki.netbeans.org/MavenBestPractices NetBeans Maven BestPractices maven.apache.org/pom.html#Aggregation Maven Documentation Multi-Module Projects (sorry about the missing protocol but couldn't post the message otherwise)

  • Securely store a password in program code?

    - by Nick
    My application makes use of the RijndaelManaged class to encrypt data. As a part of this encryption, I use a SecureString object loaded with a password which get's get converted to a byte array and loaded into the RajindaelManaged object's Key at runtime. The question I have is the storage of this SecureString. A user entered password can be entered at run-time, and that can be "securely" loaded into a SecureString object, but if no user entered password is given, then I need to default to something. So ultimately the quesiton comes down to: If I have to have some known string or byte array to load into a SecureString object each time my application runs, how do I do that? The "encrypted" data ultimately gets decrypted by another application, so even if no user entered password is specified, I still need the data to be encrypted while it goes from one app to another. This means I can't have the default password be random, because the other app wouldn't be able to properly decrypt it. One possible solution I'm thinking is to create a dll which only spits out a single passphrase, then I use that passphrase and run it through a couple of different hashing/reorganizing functions at runtime before I ultimately feed it into the secureString object. Would this be secure enough?

  • Call to CFC via Ajax-POST does not work

    - by Philipp
    We have the following problem: A CFC-method that is called from AJAX suddenly redirects the request to cfcexplorer instead of executing the request. The strange thing is, that the problem only occurs when we make the ajax call via "POST" method, like this: // This will return the HTTP Status header: // Location: http://url.to:80/CFIDE/componentutils/cfcexplorer.cfc?method=getcfcinhtml&name=web.ajax&path=/web/ajax.cfc $.post( "http://url.to/ajax.cfc", {method: "test"}, function(res) { alert("ajax.cfc POST return:" + res); } ); Making the same request as "GET" request works perfectly: // This will call the method "test" of web/ajax.cfc $.get( "http://url.to/ajax.cfc", {method: "test"}, function(res) { alert("ajax.cfc GET return:" + res); } ); This is the ajax.cfc file (dummy file): <cfcomponent> <cffunction name="test" access="remote" returntype="Any" returnformat="JSON"> <cfset j = {}> <cfset j.data = "this is the data"> <cfreturn serializeJson(j)> </cffunction> </cfcomponent> What really puzzles us is that the request did work in the past (we have a lot of code all making ajax calls via POST and CF-code that expects FORM-data to be present, so we cannot simply change the method to GET) Maybe there was some setting that has changed or similar...

  • detecting pauses in a spoken word audio file using pymad, pcm, vad, etc

    - by james
    First I am going to broadly state what I'm trying to do and ask for advice. Then I will explain my current approach and ask for answers to my current problems. Problem I have an MP3 file of a person speaking. I'd like to split it up into segments roughly corresponding to a sentence or phrase. (I'd do it manually, but we are talking hours of data.) If you have advice on how to do this programatically or for some existing utilities, I'd love to hear it. (I'm aware of voice activity detection and I've looked into it a bit, but I didn't see any freely available utilities.) Current Approach I thought the simplest thing would be to scan the MP3 at certain intervals and identify places where the average volume was below some threshold. Then I would use some existing utility to cut up the mp3 at those locations. I've been playing around with pymad and I believe that I've successfully extracted the PCM (pulse code modulation) data for each frame of the mp3. Now I am stuck because I can't really seem to wrap my head around how the PCM data translates to relative volume. I'm also aware of other complicating factors like multiple channels, big endian vs little, etc. Advice on how to map a group of pcm samples to relative volume would be key. Thanks!

  • get column names from a table where one of the column name is a key word.

    - by syedsaleemss
    Im using c# .net windows form application. I have created a database which has many tables. In one of the tables I have entered data. In this table I have 4 columns named key, name,age,value. Here the name "key" of the first column is a key word. Now I am trying to get these column names into a combo box. I am unable to get the name "key". It works for "key" when I use this code: private void comboseccolumn_SelectedIndexChanged(object sender, EventArgs e) { string dbname = combodatabase.SelectedItem.ToString(); string path = @"Data Source=" + textBox1.Text + ";Initial Catalog=" + dbname + ";Integrated Security=SSPI"; //string path=@"Data Source=SYED-PC\SQLEXPRESS;Initial Catalog=resources;Integrated Security=SSPI"; SqlConnection con = new SqlConnection(path); string tablename = comboBox2.SelectedItem.ToString(); //string query= "Select * from" +tablename+; //SqlDataAdapter adp = new SqlDataAdapter(" Select [Key] ,value from " + tablename, con); SqlDataAdapter adp = new SqlDataAdapter(" Select [" + combofirstcolumn.SelectedItem.ToString() + "]," + comboseccolumn.SelectedItem.ToString() + "\t from " + tablename, con); DataTable dt = new DataTable(); adp.Fill(dt); dataGridView1.DataSource = dt; } This is beacuse I am using "[" in the select query. But it wont work for non keys. Or if I remove the "[" it is not working for key . Please suggest me so that I can get both key as well as nonkey column names.

  • GAE python database object design for simple list of values

    - by Joey
    I'm really new to database object design so please forgive any weirdness in my question. Basically, I am use Google AppEngine (Python) and contructing an object to track user info. One of these pieces of data is 40 Achievement scores. Do I make a list of ints in the User object for this? Or do I make a separate entity with my user id, the achievement index (0-39) and the score and then do a query to grab these 40 items every time I want to get the user data in total? The latter approach seems more object oriented to me, and certainly better if I extend it to have more than just scores for these 40 achievements. However, considering that I might not extend it, should I even consider just doing a simple list of 40 ints in my user data? I would then forgo doing a query, getting the sorted list of achievements, reading the score from each one just to process a response etc. Is doing this latter approach just such a common practice and hand-waved as not even worth batting an eyelash at in terms of thinking it might be more costly or complex processing wise?

  • Sybase: how can I remove non-printable characters from CHAR or VARCHAR fields with SQL?

    - by Kenny Drobnack
    I'm working with a Sybase database that seems to have non-printable characters in some of the string fields and this is throwing off some of our processing code. At first glance, it seemed to only be newlines and carriage returns, but we also have an ASCII code 27 in there - an ESC character, some accented characters, and some other oddities in there. I have no direct access to change the database, so changing the bad data isn't an option, yet. For now I have to make do with just filtering it out. We're trying to export the table data from one database and load it into a database used by another application in a nightly batch process. Ideally, I'd like to have a function that I can pass a list of characters and just have Sybase return the data with those characters removed. I'd like to keep it something we could do in plain SQL if possible. Something like this to remove characters that are ASCII 0 - 31. select str_replace(FIELD1, (0-31), NULL) as FIELD1, str_replace(FIELD2, (0-31), NULL) as FIELD2 from TABLE So far, str_replace is the nearest I can find, but it only allows replacing one string with another. No support for character ranges and won't let me do the above. We're running on Sybase ASE 12.5 on Unix servers.

  • XAML ContextMenu gets bound to wrong row in a DataGrid

    - by Simon_Weaver
    I have a XAML based ContextMenu bound to the rows in a datagrid. It works just fine - until the grid is scrolled! This is the context menu for one of the controls in the visual tree or a DataGrid row. <data:DataGridTemplateColumn Header="Customer Details" Width="*"> <data:DataGridTemplateColumn.CellTemplate> <DataTemplate> <Grid Background="Transparent"> <!-- allows click in entire cell --> <controlsInputToolkit:ContextMenuService.ContextMenu> <controlsInputToolkit:ContextMenu> <controlsInputToolkit:MenuItem Header="{Binding CompletedOrderId,StringFormat='Create Reminder for order #\{0\}'}" CommandParameter="{Binding}"> <controlsInputToolkit:MenuItem.Command> <command:CreateReminderCommand/> </controlsInputToolkit:MenuItem.Command> <controlsInputToolkit:MenuItem.Icon> <Viewbox> <Image Width="19" Height="18" Source="../images/reminders.png" VerticalAlignment="Center"/> </Viewbox> </controlsInputToolkit:MenuItem.Icon> </controlsInputToolkit:MenuItem> <controlsInputToolkit:ContextMenu> <controlsInputToolkit:ContextMenuService.ContextMenu> ...... The ICommand is CreateReminderCommand and the CommandParameter is bound to the data item for the row itself. This works just fine - I can right click on a row and it will show me the correct text in the menu item 'Create Reminder for order 12345'. Then I scroll the datagrid down a page. If I keep right clicking on items then suddenly I'll see the wrong order number for a row. I think what must be happening is this : The DataGrid is reusing instances of MenuItem that it has previously created. How can I force a refresh of the ContextMenu when it is displayed for an item that changes? There's no 'Update method on the ContextMenu or ContextMenuService.

  • Problems with jQuery load and getJSON only when using Chrome

    - by leftend
    I'm having an issue with two jQuery calls. The first is a "load" that retrieves HTML and displays it on the page (it does include some Javascript and CSS in the code that is returned). The second is a "getJSON" that returns JSON - the JSON returned is valid. Everything works fine in every other browser I've tried - except Chrome for either Windows or Mac. The page in question is here: http://urbanistguide.com/category/Contemporary.aspx When you click on a Restaurant name in IE/FF, you should see that item expand with more info - and a map displayed to the right. However, if you do this in Chrome all you get is the JSON data printed to the screen. The first problem spot is when the "load" function is called here: var fulllisting = top.find(".listingfull"); fulllisting.load(href2, function() { fulllisting.append("<div style=\"width:99%;margin-top:10px;text-align:right;\"><a href=\"#\" class=\"" + obj.attr("id") + "\">X</a>"); itemId = fulllisting.find("a.listinglink").attr("id"); ... In the above code, the callback function doesn't seem to get invoked. The second problem spot is when the "getJSON" function is called: $.getJSON(href, function(data) { if (data.error.length > 0) { //display error message } else { ... } In this case - it just seems to follow the link instead of performing the callback... and yes, I am doing a "return false;" at the end of all of this to prevent the link from executing. All of the rest of the code is inline on that page if you want to view the source code. Any ideas?? Thanks

    I have this data frame: structure(list(month_num = 1:24, founded_month = c(4L, 5L, 6L, 7L, 8L, 9L, 10L, 11L, 12L, 1L, 2L, 3L, 4L, 5L, 6L, 7L, 8L, 9L, 10L, 11L, 12L, 1L, 2L, 3L), founded_year = c(2008L, 2008L, 2008L, 2008L, 2008L, 2008L, 2008L, 2008L, 2008L, 2009L, 2009L, 2009L, 2009L, 2009L, 2009L, 2009L, 2009L, 2009L, 2009L, 2009L, 2009L, 2010L, 2010L, 2010L), count = c(270L, 222L, 256L, 250L, 277L, 268L, 246L, 214L, 167L, 408L, 201L, 225L, 203L, 220L, 230L, 225L, 177L, 207L, 166L, 135L, 116L, 122L, 69L, 42L), month_abb = c("Apr", "May", "Jun", "Jul", "Aug", "Sep", "Oct", "Nov", "Dec", "Jan", "Feb", "Mar", "Apr", "May", "Jun", "Jul", "Aug", "Sep", "Oct", "Nov", "Dec", "Jan", "Feb", "Mar"), short_year = c("08", "08", "08", "08", "08", "08", "08", "08", "08", "09", "09", "09", "09", "09", "09", "09", "09", "09", "09", "09", "09", "10", "10", "10" ), proj = c(282, 246, 292, 298, 337, 340, 330, 310, 275, 528, 333, 369, 359, 388, 410, 417, 381, 423, 394, 375, 368, 386, 345, 330), label = c("Apr", "May", "Jun", "Jul", "Aug", "Sep", "Oct", "Nov", "Dec", "Jan\n09", "Feb", "Mar", "Apr", "May", "Jun", "Jul", "Aug", "Sep", "Oct", "Nov", "Dec", "Jan\n10", "Feb", "Mar")), .Names = c("month_num", "founded_month", "founded_year", "count", "month_abb", "short_year", "proj", "label"), row.names = c(NA, -24L), class = "data.frame") and i've got all of this done (I know the code's a bit ugly looking, pointers appreciated): p <- ggplot(m_summary2, aes(x = month_num, y = count)) p + geom_line(colour = rgb(0/255, 172/255, 0/255)) + geom_point(colour = rgb(0/255, 172/255, 0/255)) + geom_line(aes(x = m_summary2$month_num, y = m_summary2$proj), colour = rgb(18/255, 111/255, 150/255)) + geom_point(aes(x = m_summary2$month_num, y = m_summary2$proj), colour = rgb(18/255, 111/255, 150/255)) + scale_x_continuous("Month", breaks = m_summary2$month_num, labels = m_summary2$label) + scale_y_continuous("# Startups Founded") + opts(title = paste("# Startups Founded:", m_summary2$month_abb[1], m_summary2$short_year[1], "-", m_summary2$month_abb[nrow(m_summary2)], m_summary2$short_year[nrow(m_summary2)])) Now I would like to add a legend to clarify that the blue line is a projection and the green line is the current data. Thanks in advance!

  • python: how to design a container with elements that must reference their container

    - by Luke404
    (the title is admittedly not that great. Please forgive my English, this is the best I could think of) I'm writing a python script that will manage email domains and their accounts, and I'm also a newby at OOP design. My two (related?) issues are: the Domain class must do special work to add and remove accounts, like adding/removing them to the underlying implementation how to manage operations on accounts that must go through their container To solve the former issue I'd add a factory method to the Domain class that'll build an Account instance in that domain, and a 'remove' (anti-factory?) method to handle deletions. For the latter this seems to me "anti-oop" since what would logically be an operation on an Account (eg, change password) must always reference the containing Domain. Seems to me that I must add to the Account a reference back to the Domain and use that to get data (like the domain name) or call methods on the Domain class. Code example (element uses data from the container) that manages an underlying Vpopmail system: class Account: def __init__(self, name, password, domain): self.name = name self.password = password self.domain = domain def set_password(self, password): os.system('vpasswd %s@%s %s' % (self.name, self.domain.name, password) self.password = password class Domain: def __init__(self, domain_name): self.name = domain_name self.accounts = {} def create_account(self, name, password): os.system('vadduser %s@%s %s' % (name, self.name, password)) account = Account(name, password, self) self.accounts[name] = account def delete_account(self, name): os.system('vdeluser %s@%s' % (name, self.name)) del self.accounts[name] another option would be for Account.set_password to call a Domain method that would do the actual work - sounds equally ugly to me. Also note the duplication of data (account name also as dict key), it sounds logical (account names are "primary key" inside a domain) but accounts need to know their own name.

  • SQLiteDataAdapter Update method returning 0 C#

    - by Lirik
    I loaded 83 rows from my CSV file, but when I try to update the SQLite database I get 0 rows... I can't figure out what I'm doing wrong. The program outputs: Num rows loaded is 83 Num rows updated is 0 The source code is: public void InsertData(String csvFileName, String tableName) { String dir = Path.GetDirectoryName(csvFileName); String name = Path.GetFileName(csvFileName); using (OleDbConnection conn = new OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + dir + @";Extended Properties=""Text;HDR=Yes;FMT=Delimited\""")) { conn.Open(); using (OleDbDataAdapter adapter = new OleDbDataAdapter("SELECT * FROM " + name, conn)) { QuoteDataSet ds = new QuoteDataSet(); adapter.Fill(ds, tableName); Console.WriteLine("Num rows loaded is " + ds.Tags.Rows.Count); InsertData(ds, tableName); } } } public void InsertData(QuoteDataSet data, String tableName) { using (SQLiteConnection conn = new SQLiteConnection(_connectionString)) { using (SQLiteDataAdapter sqliteAdapter = new SQLiteDataAdapter("SELECT * FROM " + tableName, conn)) { using (new SQLiteCommandBuilder(sqliteAdapter)) { conn.Open(); Console.WriteLine("Num rows updated is " + sqliteAdapter.Update(data, tableName)); } } } } Any hints on why it's not updating the correct number of rows?

  • What is the Best way to databind an ASP.NET TreeView for table with many to many parent child relati

    - by Matt W
    I've got a table which has the usual ParentID, ChildID as it's first two columns in a self-referencing tree data structure. My issue is that when I pull this out and use the following code: DataSet set = DA.GetNewCategories(); set.Relations.Add( new DataRelation("parentChildCategories", set.Tables[0].Columns["CategoryParentID"], set.Tables[0].Columns["CategoryID"]) ); StringBuilder buildXml = new StringBuilder(); StringWriter writer = new StringWriter(buildXml); set.WriteXml(writer); TreeView2.DataSource = new HierarchicalDataSet(set, "CategoryID", "CategoryParentID"); TreeView2.DataBind(); I get the error: These columns don't currently have unique values I believe this is because my data has children with multiple parent nodes. This is fine for my application - I don't mind if one row of data is rendered in multiple nodes of my TreeView. Could someone shed light on this please? It doesn't seem unreasonable to have a DataSet render XML which has nodes appearing in multiple places, but I can't figure out how to do it. Thanks, Matt.

  • AudioFileWriteBytes fails with error code -40

    - by alexbw
    I'm trying to write raw audio bytes to a file using AudioFileWriteBytes(). Here's what I'm doing: void writeSingleChannelRingBufferDataToFileAsSInt16(AudioFileID audioFileID, AudioConverterRef audioConverter, ringBuffer *rb, SInt16 *holdingBuffer) { // First, figure out which bits of audio we'll be // writing to file from the ring buffer UInt32 lastFreshSample = rb->lastWrittenIndex; OSStatus status; int numSamplesToWrite; UInt32 numBytesToWrite; if (lastFreshSample < rb->lastReadIndex) { numSamplesToWrite = kNumPointsInWave + lastFreshSample - rb->lastReadIndex - 1; } else { numSamplesToWrite = lastFreshSample - rb->lastReadIndex; } numBytesToWrite = numSamplesToWrite*sizeof(SInt16); Then we copy the audio data (stored as floats) to a holding buffer (SInt16) that will be written directly to the file. The copying looks funky because it's from a ring buffer. UInt32 buffLen = rb->sizeOfBuffer - 1; for (int i=0; i < numSamplesToWrite; ++i) { holdingBuffer[i] = rb->data[(i + rb->lastReadIndex) & buffLen]; } Okay, now we actually try to write the audio from the SInt16 buffer "holdingBuffer" to the audio file. The NSLog will spit out an error -40, but also claims that it's writing bytes. No data is written to file. status = AudioFileWriteBytes(audioFileID, NO, 0, &numBytesToWrite, &holdingBuffer); rb->lastReadIndex = lastFreshSample; NSLog(@"Error = %d, wrote %d bytes", status, numBytesToWrite); return;
