  • Web-app currency input/manipulation/calculation with javascript .. there has got to be a better (fra

    - by dreftymac
    BACKGROUND: I am of the "user-input-lockdown" school of thought. Whenever possible, I try to mistrust and sanitize user input, both client side and server side; and I try to take multiple opportunities to restrict possible inputs to a known subset of possibilities, usually this means providing a lot of checkboxes and select lists. (This is from the usability side of things, I know security-wise that malicious users can easily bypass fixed user input GUI controls). PROBLEM: Anyway, the problem always arises with non-fixed input of currency. Whenever I have to accept a freely-specified dollar amount as user input, I always have to confront these problems/annoyances and it is always painful: 1) Make sure to give the user two input boxes for each currency_datapoint, one for the whole_dollar_part and another for the fractional_pennies_part 2) Whenever the user changes a currency_datapoint, provide keystroke-by-keystroke GUI feedback to let them know whether the currency_datapoint is well-formed, with context-appropriate validation rules (e.g., no negatives?, nonzero only?, numeric only!, no non-numeric punctuation! no symbols!) 3) For display purposes, every user-provided currency_datapoint should be translated to human-readable currency formatting (dollar sign, period, commas provided by the app, where appropriate) 4) For calculation purposes, every user-provided currency_datapoint has to be converted to integer (all pennies, to avoid floating point errors) and summed into a grand total with zero or more subtotals. 5) Every user-provided currency_datapoint should be displayed or displayable in a nice "tabular" format, which auto-updates as the user enters each currency_datapoint, including a baloon that warns when one or more currency_datapoints is not well-formed. I seem to be re-inventing this wheel every time I have to work with currency in Javascript on the client side (server side is a bit more flexible since most programming languages have higher-level currency formatting logic). QUESTION: Has anyone out there solved the problem of dealing with the above issues, client side, in a way that is server-side-technology-stack agnostic, (preferrably plain javascript or jquery)? This is getting old, there has to be a better way.

  • How can I have a web link perform an action in a specific desktop application?

    - by John
    The specific situation is I have a .zip file that I want to open with a certain application. However, I don't want all ZIP files associated with that application. I think the answer is that instead of saying, "download this zip file, and open it with application X" I could have the browser basically go well my desktop application to go fetch it on its own (the same way directives like itunes: mailto: or aim: do things like launch the itunes store, add buddies, etc). Thoughts?

  • Create and Call an ASP.NET Asynchronous Web Service and call it from JavaScript

    - by nickyt
    Environment: ASP.NET web applicaition jQuery, ASP.NET AJAX Currently using ASP.NET Web Services The title says it all. One, how do i create an ASP.NET web service that is asynchronous? I've seen many articles, that show example with IAsyncResult and BeginMyWebServiceMethod and EndMyWebServiceMethod, some using ThreadPool etc. I would just like to know what is the simplest way to make an asynchronous web service method call (ideally without having to implement other classes, if possible). To me it should be as simple as adding an attribute to the method (but I think that is wishful thinking), e.g. public SomeWebService : WebService { [Asynchronous] public static bool SomeCheck() { // code } } I'm open to using WCF if that makes it easier (we converted to ASP.NET 3.5 around Christmas time). Once I have the asynchronous web service created, what is the best way to call it from client-side script? Via jQuery's $ajax or ASP.NET's auto generated class for a web service that is script method?

  • Java JAX-WS web-service client: how log request & response xml ?

    - by EugeneP
    I created an implementation of LoggingHandler that implements SOAPHandler It should log whenever handleMessage triggers. [ And it is never called in my case ] then : MyService service = new MyService(); MyServicePort port = service.getPortType(); now I try this: BindingProvider bindingProvider = (BindingProvider)port; bindingProvider.getBinding().getHandlerChain().add(new LoggingHandler()); I do not see any request / response xml though. Can you suggest any solution? Maybe there's other way to see output and request xml s ?

  • ASP.NET: Unable to validate data.

  • Whats a good API for generating reports for a java web application?

    - by Ahmad
    I have a J2EE application that has a lot of reports, the situation now is the following: Report filters' values are sent to the application over DWR mainly, the data are retrieved from Oracle DB throw DB procedures and returned back to the client. However, some customization is required every now and then (new data filters, columns, ordering, ...), and these changes are painful to implement since we need to modify the JSPs, DB Procedures, the application itself, ... What API do you recommend to use for such reports?

  • Sharepoint: How to obtain the current site/web/list properly

    - by driAn
    Hi all What is the best way to obtain the current site/web/list ? Option 1 - Reusing existing objects SPSite site = SPContext.Current.Site; SPweb web = SPContext.Current.Web; SPList list = SPContext.Current.List; Option 2 - Creating new objects SPSite site = new SPSite(SPContext.Current.Site.ID); // dispose me SPweb web = site.OpenWeb(SPContext.Current.Web.ID); // dispose me SPList list = web.Lists[SPContext.Current.List.ID]; I experienced problems when using option 1 in some situations. Since then I chose the 2nd option and it worked fine so far. What is your opinion on this? I is generally better to go with option 2? Other suggestions?

  • Host ::1 resolves to remote IP

    - by thebuckst0p
    /etc/hosts files usually have this line, ::1 localhost. I thought ::1 was the equivalent of 127.0.0.1/localhost, and from my reading it seems to be the IPv6 version. So I was using it in Apache for firewalling, "Allow from ::1" and it only allowed local. Then suddenly that stopped working, so I pinged ::1 and got a remote IP address. I tracerouted it and it went through my ISP, through some Microsoft server, then another half dozen steps of asterisks... I'm not sure why this would be (the remote IP), but it doesn't seem good. I grep'd my hard drive for the remote IP and it doesn't appear anywhere. Is this some indicator that I'm being hacked, or normal behavior? Maybe my IPv6 settings are wrong? (This is a brand new MacBookPro with Snow Leopard.) Any ideas about this would be great - what is ::1 supposed to be, why would it be remote, should I be worried, how do I get it back to localhost? Thank you!

  • Computer won't reboot without waiting for a while

    - by Benjamin
    I've got an unusual problem with my computer. When ever I reboot my computer it won't boot, I get a few beeps from the BIOS and nothing else, however if I wait for a few minuets the computer will boot perfectly. I tried to count the beeps and I get around 7-9 of them; the first two are noticeably closer together than the rest. [Edit: I'm now reasonably confident it's 1 long followed by 8 short beeps.

  • Are there any web application frameworks usable with .NET 2.0?

    - by adhocgeek
    Apologies if this has been asked many, many times before - I'm afraid I couldn't find any satisfactory answers. I'm stuck in an environment (a bank) where, although we have VS 2008 on the development machines, production machines are locked down to the .Net framework 2.0 and SQL Server 2005. Are there any modern application frameworks that I could employ? I've looked at things like Spring.NET, PureMVC and ASP.NET MVC (S#arp Arch?), but I don't really have the luxury of time to investigate in depth. I don't want to initiate a war over which framework might be best, I just want to know if there are any I can actually use.

  • What are the most active Ruby forums/blogs on the web?

    I have just spent 2 days with Ruby, and my observation in last two days is that it is very difficult (as compared to say .NET/Java) to find an active forum/blogs which are helpful for Ruby (or maybe I don't know them since I am new). Which are the most common forums/blogs developers visit when they need help with Ruby (other than Stack Overflow)?

  • How to specify a web service URL within a Drupal module's simpletest?

    - by Matt V.
    I have a Drupal module that talks to a REST API on a separate server for user registration and authentication. The module runs on multiple sites which point to different servers which may run different versions of the REST API. Ideally, I'd like to be able to run each site against its own end-point, in case changes on the back end break things. Is there a way to dynamically specify a different end-point URL when running a test? Or do I have to edit the .test file for each site? I'm trying to keep the module's files as generic and flexible as possible. I guess I could have the .test file look for a .inc file that could override the URL, if needed for a particular site. Is there a better way though?

My question is "How can I paste an image from the clipboard into a field (what field is not that big issue as long as it works)", and then sent to the server. Jira has this functionality, so it should be possible! Any ideas on how to do this? Just to explain the complete workflow; I would like to have a plave to multi upload images, where the paste from clipboard also is an option. The upload will be some ajax of some sort, bt is not important in this context! Thanks

  • How to host 50 domains/sites with common Django code base

    - by Off Rhoden
    I have 50 different websites that use the same layout and code base, but mostly non-overlapping data (regional support sites, not link farm). Is there a way to have a single installation of the code and run all 50 at the same time? When I have a bug to fix (or deploy new feature), I want to deploy ONE time + 1 restart and be done with it. Also: Code needs to know what domain the request is coming to so the appropriate data is displayed.
