  • Flex DataGrid not Displaying Data

    - by asawilliams
    I have a custom dataGrid that acts more like a 2D list (if that makes sense at all). I am dynamically creating the columns and recreating the dataProvider to suit my needs. While debugging I can see that I am creating the columns and setting them to the dataGrid and creating and setting the dataProvider, but for some reason I am able to see the dataGrid and the columns but not the data. [Bindable] private var mockData:ArrayCollection = new ArrayCollection([ {value: "425341*"}, {value: "425341*"}, {value: "425341*"}, {value: "425341*"}, {value: "425341*"}, {value: "425341*"}, {value: "425341*"}, {value: "425341*"}, {value: "425341*"}]); ... <TwoDimensionalList width="100%" height="100%" numColumns="7" numRows="7" dataField="value" dataProvider="{mockData}"/> The snippet of code from the object only contains the important functions, everything else is not important (getters, setters, etc ...). While debugging I checked all the variables in the functions to make sure they were assigned and a value that I was expecting. [Snippet] public class TwoDimensionalList extends DataGrid { ... /** * Creates and sets properties of columns */ private function createColumns():void { var column:DataGridColumn; var cols:Array = this.columns; for(var i:uint=0; i < numColumns; i++) { column = new DataGridColumn("column"+i.toString()); column.dataField = "column"+i.toString(); cols[i]=column; } this.columns = cols; // go to the current gotoPage(this._currentPageNum); } /** * Sets the data for the dataprovider based on the * number of columns, rows, and page number. * * @param pageNum the page number of the data to be viewed in the DataGrids. */ private function gotoPage(pageNum:uint):void { _currentPageNum = pageNum; var startIndex:uint = (pageNum-1)*numColumns*numRows; var data:ArrayCollection = new ArrayCollection(); for(var i:uint=0; i < numRows; i++) { var obj:Object = new Object(); for(var j:uint=0; j < numColumns; j++) { if((i+(j*numRows)+startIndex) < _dataProvider.length) obj["column"+j.toString()] = String(_dataProvider.getItemAt(i+(j*numRows)+startIndex)["value"]); } data.addItem(obj); } this.dataProvider = data; } }

  • How should open source libraries be used on Windows?

    - by Jason Owen
    There are many open-source libraries that can be compiled with Visual Studio. I'm porting a program from Linux to Windows, but it depends on a number of libraries. I don't know what the best practices regarding libraries are on Windows. On Linux, these libraries are typically part of the distribution. To use sqlite on Debian, for example, you need only to install libsqlite3-dev and the include files and libraries (both static and dynamic) are automatically installed and available to your program. If you need a different version than your distribution supplies, you can compile it in your home directory, install it to ~/include and ~/lib, and set the appropriate environment variables so that your compiler includes those directories in its search path. What is the best way to use libraries that are distributed as source on Windows? If I link dynamically rather than statically, is there an easy way to copy required DLLs into the output directory to ease redistribution (assuming license requirements are met)?

  • Unable to save data in database manually and get latest auto increment id, cakePHP

    - by shabby
    I have checked this question as well and this one as well. I am trying to implement the model described in this question. What I want to do is, on the add function of message controller, create a record in thread table(this table only has 1 field which is primary key and auto increment), then take its id and insert it in the message table along with the user id which i already have, and then save it in message_read_state and thread_participant table. This is what I am trying to do in Thread Model: function saveThreadAndGetId(){ //$data= array('Thread' => array()); $data= array('id' => ' '); //Debugger::dump(print_r($data)); $this->save($data); debug('id: '.$this->id); $threadId = $this->getInsertID(); debug($threadId); $threadId = $this->getLastInsertId(); debug($threadId); die(); return $threadId; } $data= array('id' => ' '); This line from the above function adds a row in the thread table, but i am unable to retrieve the id. Is there any way I can get the id, or am I saving it wrongly? Initially I was doing the query thing in the message controller: $this->Thread->query('INSERT INTO threads VALUES();'); but then i found out that lastId function doesnt work on manual queries so i reverted.

  • 3D touch "Minority Report" style interface - what platform gets me there the fastest?

    - by Ross Braden
    I'm working on a project that requires touch interface, though the use case is desktop more than mobile. Want to start out platform agnostic, not a mobile app. There will be gridwork type of 3D objects and diagraming being represented - think AutoCAD or Minority Report. Want to build a prototype that will have hooks into a database to represent the data. Any advice on what tools to use both for the design and the development of the functionality is greatly appreciated. Thanks!

  • How do you make an installer for your python program

    - by Malcolm2608
    Im new to python, but I was thinking about making a program with python to give to my friends. They don't know much about computers so if I asked them to install python by them selves they couldn't do it, but what if I could make an installer that downloads some version of python that only has what is needed for my file to run and make an exe file that would run the .py file in its own python interpreter . I also did a Google search and saw the freezing applications I could use to make the code into exe files to distribute (cx_freeze I use python 3.2), but not all of my friends have Windows computers and I rather Have my program so in each new version it auto updates by making a patch to .py file and not completely re-installing it .

  • How do I compile on linux to share with all distributions?

    - by Andrew M
    I compiled a PHP extension on Fedora Core 12, but when I send it to someone using CentOS they get the error: "ELF file OS ABI invalid" I'm not sure what causes this running file provides the following info: ELF 64-bit LSB shared object, AMD x86-64, version 1 (GNU/Linux), not stripped An extension that loads fine provides the following from file: ELF 64-bit LSB shared object, AMD x86-64, version 1 (SYSV), not stripped So it seems I need to generate a SYSV type file for some distributions, instead of a GNU/LINUX file, no idea how though. Any pointers? Also should I be statically linking?

    - by Bob Rhubart
    Updated Business Activity Monitoring (BAM) Class | @OracleSOA Oracle SOA Team blogger Gary Barg has news for those interested in a skills upgrade. This updated Oracle University course "explains how to use Oracle BAM to monitor enterprise business activities across an enterprise in real time. You can measure your key performance indicators (KPIs), determine whether you are meeting service-level agreements (SLAs), and take corrective action in real time." Oracle Solaris 11.1 update focuses on database integration, cloud | @markfontecchio TechTarget editor Mark Fontecchio reports on the recent Oracle Solaris 11.1 release, with comments from IDC's Al Gillen. Thought for the Day "Why is composing symphonies tough? I don't know. It's just very few people in the world can do it well. And I think that's the case with upfront design.

  • Where is Win7's jump list data stored?

    - by DigiMarco
    As per Jumplist Extender, I'm trying to prevent other apps from refreshing their jump lists (it's assumed that the user WANTS to do this, seeing as this is a JL editor.) One idea is to look for file or registry changes, where the data may be stored, and prevent the data from being written to. The question is, where is the jump list data stored? It has to be somewhere! I know there's a folder location for pinned items, but I forgot what it is. It'd be great if I can get the "task" data, as well. Here's the original report.

  • Load different views depending on the category of data on tap of tableview cell iPhone sdk

    - by neha
    Hi all, In my aplication, I want a tableview with different cell structure depending upon the category of data that's getting loaded in it [I have different categories like video, editorial etc with different structure of data like video has a single label, editorial has 3 labels etc]. I can load different nib files based on the data coming from xml parser. Now when the cell is tapped, I want to show its detailed view on a new viewController. So my question is is it possible to use only 1 viewController show different fields depending upon the category of data in the cell. Or do I need to create different viewControllers for each of the categories?

  • Parent-Child relation while using object data source

    - by Saba
    Hello guys I am experiencing with a class generator I've written, which generates a class for each table in database with each table field as a property and such. Before that, I used to add a typed dataset to the project and add some tables to it. It automatically detected the relationship between tables and when I added a parent table as data source of a datagrid, I could add another datagrid and use the foreing key data member of it's bindingsource to fill it, and when someone moved the focus on parent datagrid, the data in child datagrid would change accordingly. Now that I have my classes, I add an object as data source for my 2 datagrids, but obviously it doesn't detect a parent child relation. But It'd really help if I could have that foreign key relation in my object datasources. Is there any way to have that relation in object datasource?

  • Saving ntext data from SQL Server to file directory using asp

    - by April
    A variety of files (pdf, images, etc.) are stored in a ntext field on a MS SQL Server. I am not sure what type is in this field, other than it shows question marks and undefined characters, I am assuming they are binary type. The script is supposed to iterate through the rows and extract and save these files to a temp directory. "filename" and "contenttype" are given, and "data" is whatever is in the ntext field. I have tried several solutions: 1) data.SaveToFile "/temp/"&filename, 2 Error: Object required: '????????????????????' ??? 2) File.WriteAllBytes "/temp/"&filename, data Error: Object required: 'File' I have no idea how to import this, or the Server for MapPath. (Cue: what a noob!) 3) Const adTypeBinary = 1 Const adSaveCreateOverWrite = 2 Dim BinaryStream Set BinaryStream = CreateObject("ADODB.Stream") BinaryStream.Type = adTypeBinary BinaryStream.Open BinaryStream.Write data BinaryStream.SaveToFile "C:\temp\" & filename, adSaveCreateOverWrite Error: Arguments are of the wrong type, are out of acceptable range, or are in conflict with one another. 4) Response.ContentType = contenttype Response.AddHeader "content-disposition","attachment;" & filename Response.BinaryWrite data response.end This works, but the file should be saving to the server instead of popping up save-as dialog. I am not sure if there is a way to save the response to file. Thanks for shedding light on any of these problems!

  • Understanding character encoding in typical Java web app

    - by Marcus
    Some pseudocode from a typical web app: String a = "A bunch of text"; //UTF-16 saveTextInDb(a); //Write to Oracle VARCHAR(15) column String b = readTextFromDb(); //UTF-16 out.write(b); //Write to http response In the first line we create a Java String which uses UTF-16. When you save to Oracle VARCHAR(15) does Oracle also store this as UTF-16? Does the length of an Oracle VARCHAR refer to number of Unicode characters (and not number of bytes)? And then when we write b to the ServletResponse is this being written as UTF-16 or are we by default converting to another encoding like UTF-8?

  • Getting plane slices from array data

    - by umanga
    Greetings all, I read 3d grid data (from multiple TIF images) into a structure as follows : typedef struct VolumeData{ int nx; int ny; int nz; unsigned char *data; // size is nx*ny*nz } Now I want to get the plane slices from this 1-D grid data: eg: unsigned char* getXYPlaneStack(VolumeData *vol,int z); I could implement above function because the *data array stores image stack. But i am having difficult time implement along the other axes: unsigned char* getYZPlaneStack(VolumeData *vol,int x); and unsigned char* getXZPlaneStack(VolumeData *vol,int y); any easy algorithm for this? thanks in advance.

  • Do private collaboration platform really need private file access?

    - by apasajja
    I need to make private collaboration platform, where the website is not open to public registration, and all the posts is only accessible by the members. The members is management team of a company. Along with many features, it has Announcement. When posting Announcement, it has option to upload images. I personally like it public, because the file transfer faster and can be easily integrated with CDN. I just wonder whether I need to make the image public, or only accessible by the members.

  • Challege: merging csv files intelligently!

    - by Evenz495
    We are in the middle of changing web store platform and we need to import products' data from different sources. We currently have several different csv files from different it systems/databases because each system is missing some information. Fortunatly the product ids are the same so it's possible to relate the data using ids. We need to merge this data into one big csv file so we can import in into our new e-commerce site. My question: is there a general approach when you need to merge csv files with related data into one csv file? Are there any applications or tools that helps you out?

  • Dynamically create PHPUnit tests from data-file

    - by DeletedAccount
    I have a data file with input and expected outputs. An example could be: input: output: 2 3 3 5 4 Exception 5 8 ... ... Currently I have a custom solution to read from the data file and perform a test for each {input,output} pair. I would like to convert this into a PHPUnit based solution and I would like to have one test per input using the test name forXassertY. So the first three tests would be called for2assert3(), for3assert5() and for4assertException(). I do not want to convert my existing data to tests if it's possible to create the test methods dynamically and keep the data file as the basis of these tests. I want to convert it to PHPUnit as I want to add some other tests later on and also process and view the output using Hudson. Suggestions?

  • Preferred data-format for user-data in java applications?

    - by Frederik Wordenskjold
    I'm currently developing a desktop application in java, which stores user data such as bookmarks for ftp-servers. When deciding how to save these informations, I ended up using xml, simply because I like the way xpath works. I was thinking about json too, which seems more lightweight. What is your preferred way to store data in java desktop applications (in general) and why? What about java-persistence, does that have any advantages worth noting? And how much does the size of user data matter? Its not always possible to store data in a database (or preferable), and in my experience xml does not scale well. Let me know what you think!

  • Hybrid Columnar Compression

    - by user12620172
    You heard me in the past talk about the HCC feature for Oracle databases. Hybrid Columnar Compression is a fantastic, built-in, free feature of Oracle 11Gr2. One used to need an Exadata to make use of it. However, last October, Oracle opened it up and now allows it to work on ANY Oracle DB server running 11Gr2, as long as the storage behind it is a ZFSSA for DNFS, or an Axiom for FC. If you're not sure why this is so cool or what HCC can do for your Oracle database, please check out this presentation. In it, Art will explain HCC, show you what it does, and give you a great idea why it's such a game-changer for those holding lots of historical DB data. Did I mention it's free?
