  • Where can I get a machine readable representation of world currencies and their symbols?

    - by Khanzor
    I'm using ASP.Net and would like to display currencies based on a country. I've had a look at http://www.xe.com/symbols.ph, http://www.xe.com/iso4217.php and http://www.iso.org/iso/support/faqs/faqs_widely_used_standards/widely_used_standards_other/currency_codes/currency_codes_list-1.htm Is there anywhere I can get something that I can load into a database? Or is there something built in to SQL Server 2005/ASP.Net to help with this?

  • Can a System Analyst come outside of programming?

    - by WeNeedAnswers
    Back in the day, if you wanted to be a Systems Analyst you had to work up the ranks from humble programmer. But these days there are University Courses/Programmes based on this topic alone. Is it thus valid for a graduate or post graduate to come into the world and just do systems analyst without doing the graft of being a programmer first, getting to know the nuances of what code is all about.

  • Is there a good in-browser code editor?

    - by levik
    We've all seen in-browser rich text editors, which allow you to edit colored/styled text in a WYSIWYG manner. But what about code editors, which automatically highlight code based on language rules as you type? Think Eclipse in a textarea (but without the refactoring support). Do such things exist? I imagine scaling would be a problem - larger files would be difficult to edit efficiently.

  • Dynamicall Rendering in a Scrollable Area

    - by James
    What is the generic algorithm or process that is commonly used to dynamically render portions of a scrolling area? For example, in Google Maps, when the user scrolls past the bounds of the currently rendered area, a grey checkerboard pattern is displayed within the not-yet-rendered portions while the application loads and renders those areas. I'm looking specifically for the approach, or the mathematics, related to filling a graphics area in chunks based on what has just come into view. If possible, I'm looking for anything relevant to the GDI+ process of doing so.

  • Node.js A Good authentication module ? or whats the proper way to authenticate users?

    - by Mohamed Ahmed
    I'm learning Node.js and looking forward to create a simple web application which will be based on Express and I was thinking of something like creating user groups and each group has its own users and each group has its own permissions (Just like ACL in Cakephp) So can anyone recommend a good module or whatever to do so ? Also I'm a little curious about security and how these passwords are going to be saved and what type of encryption the passwords will be encrypted in. Thanks :)

  • mySQL query: How to insert with UNION?

    - by Industrial
    Hi everybody, I am kind of new to mySQL:s union functions, at least when doing inserts with them. I have gotten the following to work based upon a example found on the net: INSERT INTO tableOne(a, b) SELECT a, $var FROM tableOne WHERE b = $var2 UNION ALL SELECT $var,$var Ok, nothing strange about that. But what happens when I want to insert a third value into the database that has nothing to do with the logic of the Select being done? Like : INSERT INTO tableOne(a, b, c ) How could that be done?

  • Application Engineering and Number of Users

    - by Kramii
    Apart from performance concerns, should web-based applications be built differently according to the number of (concurrent) users? If so, what are the main differences for (say) 4, 40, 400 and 4000 users? I'm particularly interested in how logging, error handling, design patterns etc. would be be used according to the number of concurrent users.

  • C preprocessor: using #if inside #define?

    - by Wxy
    I want to write a macro that spits out code based on the boolean value of its parameter. So say DEF_CONST(true) should be expanded into "const", and DEF_CONST(false) should be expanded into nothing. Clearly the following doesn't work because we can't use another preprocessor inside #defines: #define DEF_CONST(b_const) \ #if (b_const) \ const \ #endif Any idea about how to do it?

  • Generate table schema inspecting Excel(CSV) and import data

    - by Frank Malina
    How would I go around creating a MYSQL table schema inspecting an Excel(or CSV) file. Are there any ready Python libraries for the task? Column headers would be sanitized to column names. Datatype would be estimated based on the contents of the spreadsheet column. When done, data would be loaded to the table. I have an Excel file of ~200 columns that I want to start normalizing.

  • Show NSSegmentedControl menu when segment clicked, despite having set action

    - by enchilada
    My question is based on another question. Instead of repeating a bunch of stuff, I hope it's okay that I refer you to that other question instead: http://stackoverflow.com/questions/1203698/show-nssegmentedcontrol-menu-when-segment-clicked-despite-having-set-action/ My question is: How would the code within [self showGearMenu] look like, i.e. how would one actually use the popUpContextMenu:withEvent:forView method to accomplish what the poster of the other question wants? I ask because it seems that the question was resolved for the poster, but he never shared with us how he actually popped up the menu :)

  • iPhone XML SOAP requests or .NET Web Services

    - by CocoaNewBee
    I've been trying to to consume SOAP requests (.NET web services) and have found some pretty good tools that I wanted to share: 1) http://grabalife.com/2009/10/19/using-net-web-services-and-dataset-objects-in-your-iphone-app/ Really easy clean way to perform all the call needed for consuming the services. 2) http://code.google.com/p/mac-soapclient/ SOAP Client uses WSDL files you provide to dynamically create a graphical user interface for any given SOAP-based web service Hopefully that will help someone as much as me!!! Happy coding !

  • Response, Result, Reply, which is best?

    - by Robert Gould
    I'm refactoring some client-server code and it uses the terms Response, Result & Reply for the same thing (an answer from the server). And although its not really that important it's become hard to guess which word to use while writing new code, so I'd like to unify the three terms into one and do the appropriate refactoring, but I'm not sure which word is the "best", if there is such a thing. Any suggestions based on precedence and standards towards naming for this case?

  • How to effectively measure difference in a run-time.

    - by Knowing me knowing you
    Guys, in one of the excersises in TC++PL B.S. asks to: "Write a function that either returns a value or that throws that value based on an argument. Measure the difference in run-time between the two ways." Great pity he never explaines how to measure such things. I'm not sure if I'm suppose to write simple "time start, time end" counter or maybe there are more effective and practical ways to do it? Thanks in advance.

  • Memory leak when application loads in iPhone

    - by iPhoneDev
    I have a navigation based template, when I run my application using Instruments, the very first memory leak comes under: Leak Object: Malloc 128 bytes Responsible Library: CoreGraphics Responsible Frame: open_handle_to_dylib_path I don't know where this leak is coming from and how remove this. If it's a default leak, then I think I don't need to worry about it. But if it's not then I have to find a way to remove the leak.

  • How to capture the event if a new process (application!) is started?

    - by Marcus
    I would like to have some eventhandler which raise if a new application is started. I've heard that this is possible by using a hook but the only examples I can find are based on mouse/keyboard events. What is an example link of how I can create such a hook in C#? Oh and btw: Nope, I don't want to use WMI which could be a solution as well but it's not an option in my case.
