  • [Newbie] How to join mysql tables

    - by Ivan
    I've an old table like this: user> id | name | address | comments And now I've to create an "alias" table to allow some users to have an alias name for some reasons. I've created a new table 'user_alias' like this: user_alias> name | user But now I have a problem due my poor SQL level... How to join both tables to generate something like this: 1 | my_name | my_address | my_comments 1 | my_alias | my_address | my_comments 2 | other_name | other_address | other_comments I mean, I want to make a "SELECT..." query that returns in the same format as the "user" table ALL users and ALL alias.. Something like this: SELECT user.* FROM user LEFT JOIN user_alias ON `user`=`id` but it doesn't work for me..

  • Spring Weblfow 2 - Double Submit

    - by John W.
    Hello All, I am investigating a possible issue with double submits and I am looking at the possibilty of a double submit from a webflow execution. I have read many times that webflow will handle double submits, there are plenty references here. However I then came across I a forum response on the spring source forums contradicting what I read saying, SWF synchronizes on the conversation. Only one request will be processed at a time per conversation. Take note that if you're using snapshots, then it's possible repeatedly clicking on the submit button will generate a second request. I would recommend setting history to invalidate or discard in the transition from your view-state. We do have snapshots enabled but the book notes that using snapshots actually allows to solve the double submits. Does anyone have any insight on this? Thanks.

  • How to create multiple tables with the same schema using SQLite jdbc

    - by Space_C0wb0y
    I want to split a large table horizontally, and I would like to make sure that all three of them have the same schema. Currently I am using this piece of code to create the tables: statement .executeUpdate("CREATE TABLE AnnotationsMolecularFunction (Id INTEGER PRIMARY KEY ASC AUTOINCREMENT, " + "ProteinId NOT NULL, " + "GOId NOT NULL, " + "UNIQUE (ProteinId, GOId)" + "FOREIGN KEY(ProteinId) REFERENCES Protein(Id))"); There is one such statement for each table. This is bad, because if I decide to change the schema later (which will most certainly happen), I will have to change it three times, which begs for errors, so I would like a way to make sure that the other tables have the same schema without explicitly writing it again. I can use: statement .executeUpdate("CREATE TABLE AnnotationsBiologicalProcess AS SELECT * FROM AnnotationsMolecularFunction"); to create the other tables with the same columns, but the constraints are not aplied. I could of course just generate the same query-string three times with different table-names in Java, but I would like to know if there is an SQL-way of achieving this.

  • Is there a tool for generating a DSL parser that does not require a runtime for the resultant parser

    - by Chris
    I'm doing a lot of work with a DSLs at the moment and was wondering if anyone knew of a tool that could generate a parser for my bnf specification that does not require a run-time library (pure java source parser)? I'm committed to using XTEXT for a future Eclipse plug-in but I need a nice small version for my library itself and don't want to add another jar dependency. It seems that ANTLR requires a run-time to parse files and I performed a Google search with no avail. Can anyone help out? Thanks, Chris

  • Quickest and easiest way to implement speech to text conversion for a small speech subset.

    - by sgtpeppers
    Hi, I want to implement a system that receives speech through a microphone on my Mac OS x. I know arbitrary speech recognition is close to impossible without training the system so I'm willing to restrict it to 10 simple sentences. It must recognize with a high degree of accuracy which of these 10 sentences are being spoken, generate the text and add an entry to a remote MySQL database. With these being the architecture of the system I want to implement, could anyone give me an overview of what would be the best way to go about implementing this system? I'm looking for ideas like open source libraries to minimize the coding as this is just a prototype application for a demonstration. Basically I'm looking for a quick and easy solution. Thanks!

  • A tool or framework extension or code snippet for logging the internal state of objects?

    - by George Mauer
    When spiking on how something works or when my unit test behave in an unpredictable manner I usually have to drop into debug mode. 99% of my time in debug mode is spent checking the values of fields on objects to verify its state. I already have log4net set up, it would seem that if I could easily add a line of code to log out the state of objects I could remove most of my need to start up the bulky debugger. The problem is of course that to expose object state implicitly you need to manually override each object's ToString() method. What I would like to be able to do is the ability to do logger.LogState(someObject) and have logged out the object state including at least a formatted list of all the private variables, references (to some arbitrary depth), and collections. Does anyone know a tool/framework/code snippet that can be used to generate a string of the internal state of any object? I could of course write one myself but its a non-trivial problem and I'd prefer something someone has put some thought into.

  • Using boost unordered map

    - by Amrish
    Guys, I am using dynamic programming approach to solve a problem. Here is a brief overview of the approach Each value generated is identified using 25 unique keys. I use the boost::hash_combine to generate the seed for the hash table using these 25 keys. I store the values in a hash table declared as boost::unordered_map<Key_Object, Data_Object, HashFunction> hashState; I did a time profiling on my algorithm and found that nearly 95% of the run time is spent towards retrieving/inserting data into the hash table. These were the details of my hash table hashState.size() 1880 hashState.load_factor() 0.610588 hashState.bucket_count() 3079 hashState.max_size() 805306456 hashState.max_load_factor() 1 hashState.max_bucket_count() 805306457 I have the following two questions Is there anything which I can do to improve the performance of the Hash Table's insert/retrieve operations? C++ STL has hash_multimap which would also suit my requirement. How does boost libraries unordered_map compare with hash_multimap in terms of insert/retrieve performance.

  • Thumbnails from HTML pages created and used automatically in web application

    - by Jesper Rønn-Jensen
    I am working on a Ruby on Rails app that visualizes product trees. The tree is built of nodes an everything is rendered in HTML/CSS3. Some of the products make several hundred SQL queries as the tree builds up (up to 800 queries on the biggest tree). I'd like to have small thumbnails of each tree to present it on an index page. So rendering each tree once again and modifying CSS to make a tiny representation is an option. But i think it's probably easier to generate thumbnails, crop, cache, and show these on the index page. Any ideas on how to do this? Any links/articles/blog posts that could help me?

  • Is there a standard Java utility to parse XSD files at runtime?

    - by Andrew
    I've been looking around for a way to programmatically parse XSD files to generate an XML mapping so that I can take any XSD file and create a parser that will parse any XML file that conforms to it, and my google-fu has been coming up short. XSOM looks promising, as it will parse an XSD file and make all its attributes available in a straight forward way. Are there any other options or standard libraries available that will produce an XML file parser from an XSD file? [Conclusion] Thanks everyone for your responses, they were a real help. I was able to write implementations using JAXP, Eclipses EMF and in XSOM that all worked as desired. JAXP was very straight forward and easy to learn and do. EMF was actually a pain to get going properly, there were so many jars that had to be included for it to work standalone that I would not recommend it. XSOM was even simpler than the JAXP implementation, so I went with it in the end.

  • Preserve images in Excel headers using Apache POI

    - by ddm
    I am trying to generate Excel reports using Apache POI 3.6 (latest). Since POI has limited support for header and footer generation (text only), I decided to start from a blank excel file with the header already prepared and fill the Excel cells using POI (cf. question 714172). Unfortunately, when opening the workbook with POI and writing it immediately to disk (without any cell manpulation), the header seems to be lost. Here is the code I used to test this behavior: public final class ExcelWorkbookCreator { public static void main(String[] args) { FileOutputStream outputStream = null; try { outputStream = new FileOutputStream(new File("dump.xls")); InputStream inputStream = ExcelWorkbookCreator.class.getResourceAsStream("report_template.xls"); HSSFWorkbook workbook = new HSSFWorkbook(inputStream, true); workbook.write(outputStream); } catch (Exception exception) { throw new RuntimeException(exception); } finally { if (outputStream != null) { try { outputStream.close(); } catch (IOException exception) { // Nothing much to do } } } } }

  • Is my approach correct to replicate this form with Reportlab?

    - by Wes
    I need to generate the form seen here using Python/reportlab. http://www.flickr.com/photos/49740282@N06/4563137758/sizes/o/ I am attempting to do this by creating a custom flowable for the header at the top (with the boxes drawn) and then having a table flowable for the jewelry table below. What shows as the JEWELRY table for this example could potentially be multiple tables. I am having trouble getting my drawn header to "flow". It gets drawn, but then my table data overlays it instead of appearing below it. This is my first project with reportlab. Before I really get into debugging this, I would like to know from someone with reportlab experience if my approach is correct here. Thanks!

  • How to stop nant exec task putting ( ) around command line

    - by Sam
    I have looked through the nant documentation and sourceforge faq and can't find the answer to this question. The exec task in nant puts ( ) around the command line parameters it generates, so for example this task below would generate: mallow ( -1 ) <exec program="${build.tools.wix}\mallow.exe" workingdir="${build.out.xxx}"> <arg value="-1" /> </exec> The other open source tool I'm using - mallow - cannot handle this. Does anyone know of a way to stop nant putting the ( ) around the arguments? Thanks.

  • Dealing with XML in ASP.NET MVC

    - by Matt W
    I have a block of XML in a database which is easy enough to pull out using ASP.NET MVC, however I would like to access and modify the XML in an way more consistent with class instances. Is there a way to get the MVC (or any other model) to generate a data access (or perhaps Entity) class set from the DB-stored XML? If the above is rather obtuse, the question could be summarised as; What method would you use to best access and modify XML stored in a database from an ASP.NET MVC application? Thanks, Matt.

  • In OpenGL vertex shader, gl_Position doesn't get homogenized..

    - by KJ
    Hi everyone, I was expecting gl_Position to automatically get homogenized (divided by w), but it seems not working.. Why do the followings make different results? 1) void main() { vec4 p; ... omitted ... gl_Position = projectionMatrix * p; } 2) ... same as above ... p = projectionMatrix * p; gl_Position = p / p.w; I think the two are supposed to generate the same results, but it seems it's not the case. 1 doesn't work while 2 is working as expected.. Could it possibly be a precision problem? Am I missing something? This is driving me almost crazy.. helps needed. Many thanks in advance!

    - by okhalid
    Hi, I have a installation setup with works like this: /exec.exe /some-command This whole setup is located on a shared disk to which my target machine have access to. All i want is to create a small MSI wrapper that basically executes the above command. I don't need to any other fancy things? I looked up on the web; there are tools that create MSI for you but they generate huge amount of other things with them as well. My need is very simple and straight forward. It would be great if some could help me with this issue. Thanks, Omer

  • Using java classes in Grails

    - by RN
    I have a Java\Spring\Hibernate application - complete with domain classes which are basically Hibernate POJOs There is a piece of functionality that I think can be written well in Grails. I wish to reuse the domain classes that I have created in the main Java app What is the best way to do so ? Should I write new domain classes extending the Java classes ? this sounds tacky Or Can I 'generate' controllers off the Java domain classes ? What are the best practices around reusing Java domain objects in Grails\Groovy I am sure there must be others writing some pieces in grails\groovy If you know about a tutorial which talks about such an integration- that would be awesome !!! PS: I am quite a newbie in grails-groovy so may be missing the obvious. Thanks !!!

  • Rub, regex, sentences

    - by Perello
    I'm currently building a code generator, which aim to generate boiler plate for me once i wrote the templates and/or translations, whatever the language i have to work with, and it has an educationnal part :p. So i have a problem with a regex in ruby. The regex aim to select whatever is between {{{ and }}}, so i can generae functions according to my needs. My regex is currently : /\{\{\{(([a-zA-Z]|\s)+)\}\}\}/m My test data set {{{Demande aaa}}} = {{{tagadatsouintsouin tutu}}} The results are : [["Demande aaa", "a"], ["tagadatsouintsouin tutu", "u"]] So the regex pick each time the last character twice. But, that's not exactly what i want, my need is more about this : /\{\{\{((\w|\W)+)\}\}\}/m But this as a flaw too, the results : [["Demande aaa}}} = {{{tagadatsouintsouin tutu", "u"]] Whereas, i wish to get [["Demande aaa"],["tagadatsouintsouin tutu"]] Any ideas to correct theses regex ? I could use 2 sets of delimiters, but it won't learn me anything.

  • High density Silverlight charting control

    - by ahosie
    I've been looking into Silverlight charting controls to display a large number of samples, (~10,000 data points in five separate series - ~50k points all up). I have found the existing options produced by Dundas, Visifire, Microsoft etc to be extremely poor performers when displaying more than a few hundred data points. I believe the performance issues with existing chart controls is caused by the heavy use of vector graphics. Ergo one solution would be a client-side chart control that uses the WritableBitmap class to generate a raster chart. Before I fall too far down the wheel re-invention rabbit hole - has anyone found a third party or OSS control that will manage large numbers of data points on a sparkline?

  • Code Golf: Beehive

    - by LiraNuna
    The challenge The shortest code by character count that will generate a beehive from user input. A beehive is defined a a grid of hexagons in a size inputted by the user as two positive numbers greater than zero (no need to validate input). The first number (W) represents the width of the beehive - or - how many hexagons are on each row. The second number (H) represents the height of the beehive - or - how many hexagons are on each column. A Single hexagon is made from three ASCII characters: _, / and \, and three lines: __ / \ \__/ Hexagons complete each other: the first column of the beehive will be 'low', and the second will be high - alternating and repeating in the same pattern forming W hexagons. This will be repeated H times to form a total of WxH hexagons. Test cases: Input: 1 1 Output: __ / \ \__/ Input: 4 2 Output: __ __ __/ \__/ \ / \__/ \__/ \__/ \__/ \ / \__/ \__/ \__/ \__/ Input: 2 5 Output: __ __/ \ / \__/ \__/ \ / \__/ \__/ \ / \__/ \__/ \ / \__/ \__/ \ / \__/ \__/ Input: 11 3 Output: __ __ __ __ __ __/ \__/ \__/ \__/ \__/ \__ / \__/ \__/ \__/ \__/ \__/ \ \__/ \__/ \__/ \__/ \__/ \__/ / \__/ \__/ \__/ \__/ \__/ \ \__/ \__/ \__/ \__/ \__/ \__/ / \__/ \__/ \__/ \__/ \__/ \ \__/ \__/ \__/ \__/ \__/ \__/ Code count includes input/output (i.e full program).

  • Java applet - access denied to file on same web server

    - by me_here
    I've written a simple Java applet to generate a technical image based upon some data in a CSV file. I'm passing in the CSV file as a parameter to the applet: <applet code = "assaymap.AssayMapApplet" archive = "http://localhost/applet_test/AssayMap.jar" height="600px" width="800px"> <param name="csvFile" value="http://localhost/applet_test/test.csv"> </applet> As far as I understood applet security restrictions, an applet should be able to read data from the host they're on. These applets here http://www.jalview.org/examples/applets.html are using the same approach of passing in a text data file as a parameter. So I'm not sure why my own applet isn't working. The error message I get thrown is: Error with processing the CSV data. java.security.AccessControlException: access denied (java.io.FilePermission http:\localhost\applet_test\test.csv read)

  • Internet Explorer discards cookie when printing?

    - by Gareth Saul
    I have an unusual issue with this page: http://reports.liftlogger.com/FleetReport/Status/ (username stackoverflow / password stackoverflow). The page loads and renders correctly in IE7/8. However, the graph does NOT print correctly. When printing or print previewing, the graph fails to load. I've identified that when printing, the browser attempts to reload the image, but does not send the ASPXAUTH authentication cookie along with it. This is required to generate the image (due to permission enforcement in the back-end). Can anyone help me identify why IE decides not to send this cookie, and is there a fix? Regards Gareth
