  • Resources for how to design graph/charts well

    - by wesgarrison
    One of my projects needs to show users where they rank in certain calculations. I inherited the graph structure from the previous programmer and had to leave it alone while I worked on other parts of the site. It's time to make the graphs more meaningful, so I'm looking for books/websites/etc about graphs. (Not graph theory!) Charts that convey comparisons at a glance. Everyone suggests The Visual Display of Quantitative Information by Edward Tufte and that's spot on for what I'm looking for, so anything related to that would be great. Naturally, personal experience about what to do or not would be helpful as well.

  • getting mysql_insert_id() while using ON DUPLICATE KEY UPDATE with PHP

    - by julio
    Hi-- I've found a few answers for this using mySQL alone, but I was hoping someone could show me a way to get the ID of the last inserted or updated row of a mysql DB when using PHP to handle the inserts/updates. Currently I have something like this, where column3 is a unique key, and there's also an id column that's an autoincremented primary key: $query ="INSERT INTO TABLE (column1, column2, column3) VALUES (value1, value2, value3) ON DUPLICATE KEY UPDATE SET column1=value1, column2=value2, column3=value3"; mysql_query($query); $my_id = mysql_insert_id(); $my_id is correct on INSERT, but incorrect when it's updating a row (ON DUPLICATE KEY UPDATE). I have seen several posts with people advising that you use something like INSERT INTO table (a) VALUES (0) ON DUPLICATE KEY UPDATE id=LAST_INSERT_ID(id) to get a valid ID value when the ON DUPLICATE KEY is invoked-- but will this return that valid ID to the PHP "mysql_insert_id()" function? Thanks for any advice.

  • How to organize Enterprise scale Composite Applications (CAG)

    - by David
    All QuickStarts and RI examples in the CAG documentation are good but I lack the more Enterprise scale examples. Let's say we have 40+ modules, each containing a Proxy,Facade,PresentationModel,Model and Views. Each module also makes calls to a Module-specific WCF service which is to be hosted in IIS or in a stand-alone console host. Our approach have been to include the UI-module, service-module and related tests into one solution so they can be developed and tested separately from other modules. My problem is how the hosting of the services should be done when the services are in separate modules and how to actually run the separate module together with the rest of the application-modules when I press F5. Is there a best practise for this? I guess it has been done before?

  • How can I download information from bank accounts?

    - by Eric Anastas
    There are a number of free finance tracking sites out there like mint.com, wesabe.com etc.. . I've tried all of them and all seem to miss the mark in one way or another. I'm interested in creating my own website, or possibly just a stand alone windows program for tracking my finances in ASP.NET or C#.NET. I'm assuming the answer is no, but is there any way that a personal developer can download transactions from financial websites like these? I know once you login to most financial sites you can download a CSV or Quicken file. Yet I really like how I can log-in to my Mint.com account and update all my accounts with one click.

  • NSData release is not reclaiming memory

    - by ctpenrose
    iPhoneOS 3.2 I use NSKeyedUnarchiver's unarchiveObjectWithFile: to load a custom object that contains a single large NSData and another much smaller object. The dealloc method in my custom object gets called, the NSData object is released, its retainCount == 1 just before. Physical memory does not decrement by any amount, let alone a fraction of the NSData size, and with repetition memory warnings are reliably generated: I have test until I actually received level 2 warnings. =( NSString *archivePath = [[[NSBundle mainBundle] pathForResource:@"lingering"] ofType:@"data"] retain]; lingeringDataContainer = [[NSKeyedUnarchiver unarchiveObjectWithFile:archivePath] retain]; [archivePath release]; [lingeringDataContainer release]; and now the dealloc.... - (void) dealloc { [releasingObject release]; [lingeringData release]; [super dealloc]; } Before release: (gdb) p (int) [(NSData *) lingeringData retainCount] $1 = 1 After: (gdb) p (int) [(NSData *) lingeringData retainCount] Target does not respond to this message selector.

  • Tools and ways to generate HTML help for built-in help system (QtHelp)?

    - by BastiBense
    Hello, I'm in the progress of implementing a built-in help system based on QtHelp into my application. Since QtHelp is based on Qt's help collection files, I need to produce a set of HTML pages. Since I won't be writing the documentation alone (a few of my colleagues will write, too), I am looking for the best way to produce these files. We are internally using a Wiki, and I know that the documentation should be written in some kind of markup language instead of giving all authors a WYSIWYG HTML editor. So my question is, are there tools out there which help with the process of generating documentation that can be exported as a set of HTML files, and possibly, as PDFs, too?. Thanks in advance! Update: I'm already using Doxygen for C++ documentation generation. But I'm not exactly looking for an API-Documentation generator, but something like LaTeX, which allows you to format the documentation contents like a markup document (much like a Wiki).

  • Using SQL Server for WSS 3.0 instead of Windows Internal database

    - by val
    Hi Folks, There are actually two related questions: is it possible or advisable to use a full blown stand-alone SQL server for SharePoint Services WSS3.0 instead of the supplied windows internal database it comes with? The client I am working for is asking to utilize their existent SQL server for all WSS content databases to possibly minimize admin effort and improve performance. As well, would you advise to install WSS on one physical server and the content database on another server? Any gain in performace? Practicality? ect. The default is WSS and all of its databases are installed on the same single server. We don't really need a farm setup of MOSS, because the WSS capabilities are enough for our needs. Thanks, Val

  • Conditionally execute a task after building a solution with MSBuild + TFS

    - by SoMoS
    Hello, I'm using MSBuild with TFS and I have to build 4 solutions. When the compilation is done I should launch upon to 4 different Exec tasks depending on wherever the compilation was successful or not. I know how to do that with MSBuild alone using targets with conditions using the var $(BuildBreak) because I can do build solution - check result - exec task - build ... but I don't know how to do that with the TFS extensions ... any help will be very appreciated. Thanks mates.

  • Can a .csv file be used as a data source in Visual Studio 2008?

    - by Kevin
    I'm pretty new to C# and Visual Studio. I'm writing a small program that will read a .csv file and then write the records read to a SQL Server database table. I can manually parse the .csv file, but I was wondering if it is possible to somehow "describe" the .csv file to Visual Studio so that I can use it as a data source? I should mention that the first two lines in the .csv file contain header information and the following lines are the actual comma-delimited data. Also, I should mention that this program is a stand-alone console program with no user interface.

  • How to leverage Spring Integration in a real-world JMS distributed architecture?

    - by ngeek
    For the following scenario I am looking for your advices and tips on best practices: In a distributed (mainly Java-based) system with: many (different) client applications (web-app, command-line tools, REST API) a central JMS message broker (currently in favor of using ActiveMQ) multiple stand-alone processing nodes (running on multiple remote machines, computing expensive operations of different types as specified by the JMS message payload) How would one best apply the JMS support provided by the Spring Integration framework to decouple the clients from the worker nodes? When reading through the reference documentation and some very first experiments it looks like the configuration of an JMS inbound adapter inherently require to use a subscriber, which in a decoupled scenario does not exist. Small side note: communication should happen via JMS text messages (using a JSON data structure for future extensibility).

  • What's the topmost iframe in the same domain?

    - by Jakob Stoeck
    How can I get the topmost iframe which is in the same domain, i.e. iframe level 1 example.org iframe level 2 example.org iframe level 2 example.org iframe level 3 example.org <-- would give me iframe level 1 iframe level 1 other-example.org iframe level 2 example.org iframe level 2 example.org iframe level 3 example.org <-- would give me iframe level 2 iframe level 1 other-example.org iframe level 2 example.org iframe level 2 example.org <-- would give me iframe level 2 (this) I need it because I have a website which should work in an iframe of another domain and stand-alone. In this website there are scripts which depend on window.top which shouldn't be top but the topmost iframe in the same domain.

  • What are the lesser known but cool data structures ?

    - by f3lix
    There a some data structures around that are really cool but are unknown to most programmers. Which are they? Everybody knows linked lists, binary trees, and hashes, but what about Skip lists, Bloom filters for example. I would like to know more data structures that are not so common, but are worth knowing because they rely on great ideas and enrich a programmer's tool box. PS: I am also interested on techniques like Dancing links which make interesting use of the properties of a common data structure. EDIT: Please try to include links to pages describing the data structures in more detail. Also, try to add a couple of words on why a data structures is cool (as Jonas Kölker already pointed out). Also, try to provide one data-structure per answer. This will allow the better data structures to float to the top based on their votes alone.

  • Query joining in sql server 2005

I need that 5 records to display after join..... How can I do it?

  • Many to Many DataSet Insert to Database using Stored Procedures

    - by Jonn
    I'm trying to do a many-to-many bulk insert to the database using a list of three different types of models. The only tools I can use are stored procedures and datasets. (But I can't use DataSet fills or DataAdapters, just plain ol' Stored Procedures). Is there an easy way to pass multiple values, let alone, pass three different lists and bulk insert them to a table in the database using stored procedures? (As specified in the title, the three tables are actually two tables and a third table to establish the many-to-many relationship between the two.)

  • How can I override an HTML "rules" attribute using CSS?

    - by ajoten
    The DITA Open Toolkit automatically inflicts some inline table attributes when one publishes to HTML, including frame="border" and rules="all". I need to override this "rules" attribute using CSS styles for cells, and while I can get the desired result in IE and Chrome, Firefox puts solid black gridlines in the table and refuses to budge on the matter. Obviously I can't edit the HTML, company policy is to not edit the XSLT, so how can I remove these gridlines using CSS alone? I've tried various cunning combinations of border-xxxxxx styles and given them !important declarations to no effect. Thanks, Andrew

  • Visual Studio Debugger Voodoo

    - by LoveMeSomeCode
    Ok, maybe this isn't so amazing considering I don't really understand how the debugger works in the first place, let alone Edit and Continue, which is totally amazing. But I was wondering if anyone knew what the debugger is doing with variable declarations in this scenario. I can be debugging through my code, move the line of execution ahead - past a variables initial declaration and assignment, and the code still runs ok. If it's a value type it will have it's default value, for a ref type, null. So if I create a function that uses a variable before it's declared it won't compile, but if I use the debugger to run it that way it will still run without error. Why is this? And is this related to the fact that you can't put a breakpoint on a declaration?

  • using ruby test and selenium grid how can I keep the same browser window for multiple tests?

    - by George Horlacher
    Each of my tests start a new selenium client browser and tear it down so they can run stand alone with this code: def setup if $selenium @selenium = $selenium else @selenium = Selenium::SeleniumDriver.new("#$sell_server", 4444, "#$browser", "http://#$network.#$host:2086", 10000); @selenium.start end @selenium.set_context("test_login") end def teardown @selenium.stop unless $selenium assert_equal [], @verification_errors end What I'd like is to run a suite of tests that all use the same browser and don't keep opening and closing new browsers for every test. I've tried using $selenium as a global object / browser but each test still opens up a new browser and closes it. How should this be done?

  • SQL Server Agent 2005 job runs but no output

    - by alimack
    Essentially I have a job which runs in BIDS and as as a stand lone package and while it runs under the SQL Server Agent it doesn't complete properly (no error messages though). The job steps are: 1) Delete all rows from table; 2) Use For each loop to fill up table from Excel spreasheets; 3) Clean up table. I've tried this [MS page][1] (steps 1 & 2), didn't see any need to start changing from Server side security. Also SQLServerCentral.com for [this page][2], no resolution. How can I get error logging or a fix? Note I've reposted this from Server Fault as it's one of those questions that's not pure admin or programming. I have logged in as the proxy account I'm running this under, and the job runs stand alone but complains that the Excel tables are empty?

  • How small is *too small* for an opensource project?

    - by Adam Lewis
    I have a fair number of smaller projects / libraries that I have been using over the past 2 years. I am thinking about moving them to Google Code to make it easier to share with co-workers and easier to import them into new projects on my own environments. The are things like a simple FSMs, CAN (Controller Area Network) drivers, and GPIB drivers. Most of them are small (less than 500 lines), so it makes me wonder are these types of things too small for a stand alone open-source project? Note that I would like to make it opensource because it does not give me, or my company, any real advantage.

  • How to convert JavaScript dictionary into Python syntax

    - by Sputnix
    Writing out javascript dictionary from inside of JavaScript- enabled application (such as Adobe) into external .jsx file (or any other .txt file) the context of resulted file dictionary looks like: ({one:"1", two:"2"}) (Please note that each dictionary keys are written as they are the variables name (which is not true). A next step is to read this .jsx file with Python. I need to find a way to convert ({one:"1", two:"2"}) into Python dictionary syntax such as: {'one':"1", 'two':"2"} It has been already suggested that instead of using JavaScript's built-in dict.toSource() it would make more sense to use JSON which would write a dictionary content in similar to Python syntax. But unfortunately using JSON is not an option for me. I need to find a way to convert ({one:"1", two:"2"}) into {'one':"1", 'two':"2"} using Python alone. Any suggestions on how to achieve it? Once again, the problem mostly in dictionary keys syntax which inside of Python look like variable names instead of strings-like dictionary keys names: one vs "one"

  • How to instantly termainate an un-supervised script on demand?

    - by errr
    I have a GUI which resembles an interpreter. It allows the user to write a script in Jython (implementation of Python in Java) and run it whenever he wants. Apart from that, I also wish to allow the user to instantly terminate the run whenever he wants. Thing is, I don't really know how to do it. The script is being run on a different Thread, but I don't know of any secure way to stop/interrupt/terminate a thread in the middle of its run, let alone not knowing what is being run by the thread/script (it could be a simple task or maybe some sort of a heavy SQL query against a DB, and a DB is something which requires careful resource handling). How can I instantly terminate such run on demand?

  • Determining Long Tap (Long Press, Tap Hold) on Android with jQuery

    - by Volomike
    I've been able to successfully play with the touchstart, touchmove, and touchend events on Android using jQuery and an HTML page. Now I'm trying to see what the trick is to determine a long tap event, where one taps and holds for 3 seconds. I can't seem to figure this out yet. I'm wanting to this purely in jQuery without Sencha Touch, JQTouch, jQMobile, etc. I like the concept of jQTouch, although it doesn't provide me a whole lot and some of my code breaks with it. With Sencha Touch, I'm not a fan of moving away from jQuery into Ext.js and some new way of doing Javascript abstraction, especially when jQuery is so capable. So, I want to figure this out with jQuery alone. I've been able to do many jQTouch and Sencha Touch things on my own using jQuery. And jQMobile is still too beta and not directed enough to the Android yet.

  • Merge changes when a file on a branch has split into two files on the master

    - by carleeto
    This is basically the result of a massive class C on the master having been refactored down the line into two smaller classes, C1 and C2. C was then made a subclass of C2 and cut down to a skeletal version for backward compatibility. So from that point on, master contained C, C1 and C2. On that master commit git said C was renamed to C1. The branch was last updated before this happened. (All C++ code, if it helps to visualize the files involved) Obviously, when I tried a rebase of the branch onto master, there were conflicts that needed to be resolved. As usual, I used mergetool. So now the mergetool comes up with the following: On Local, I have the skeletal version of C. Base and Remote have a bunch of changes to C. Because the skeletal version of C exists on Local, I conclude that the changes from Base and Remote should actually go into C1, leaving C alone. My question is, how do I do this?

  • Android Template Application?

    - by stormin986
    I have built an application that I want to use as the foundation for a few other variants. The variants will come from assets / resource files and a unique AndroidManifest.xml. However, I want to be able to leave all the application code alone (modifying the package of all my classes, etc). I'm having a hard time figuring out how to do so. My first thought was to simply have my main application in its own package, and then specify the specific application package in the manifest. However, this gives me issues with the generated R.java class, since it is generated to be in the main application's package. Anyone have any thoughts on how to accomplish this? To have a code baseline, and the application variants happen in resources/assets and the manifest?
