  • Get controller method caller (3rd party webservice)

    - by bastijn
    Is it possible to retrieve the URL of a 3rd party webservice calling my controller method? Things like Request.Current.Url refer to my own URL (/someController/someAction/). The 3rd party webservice is sending HTTP POST data to my /someController/someAction and I wish to send back a HTTP POST message to the caller of the method, the 3rd party webservice, without using return Content["some response"] which will force me to exit the method. Since the answer is plain text I would like to send it using HTTP Post. What I actually try to do is respond to the calling webservice without exiting my method (return Content() will exit) so I can call other methods to process the data send to me by the webservice. I want to first tell the webservice I received their stuff and than process, in this way when a processing error occurs the webservice at least will not resend old data. Is there another way to do this than building your own HTTP post?

  • What lessons have you learned about using a wiki as a development tool?

    - by Vivek Kodira
    I'd asked a question a while back about ways to encourage my team to collaborate. The tool we use is a wiki. Since this is the first time we are using the wiki (formally and as a team), we are learning by committing mistakes. One of the lessons has been that a wiki isn't suitable for tracking activities. It is better to use a tool built for-the-job (will elaborate if necessary). Are there other such anti-patterns? What development tasks would you NOT recommend using a wiki for (even though it may seem suitable at first glance)? Edit: Making this a community-wiki since it is probably unlikely that there will be 'one' right answer.

  • Digester: Extracting node name for a map<tagname, value>

    - by enguerran
    My question is close to this one: Digester: Extracting node name Even with the answer, I can't find out. Here is my xml file (from smartgwt RestDataSource POST): <data> <isc_OID_14> <attribute1>value1</attribute1> <attribute2>value2</attribute2> </isc_OID_14> </data> I would like to create, with Commons Digester, the following map : {attribute1=value1, attribute2=value2} I already have those lines: digester = new Digester(); digester.addObjectCreate("data", HashMap.class); // some "put" rules matching something like data/* return digester.parse(myFile); I do not know the list nor the name of tags in the <data><sourceId /></data>. isc_OID_14 or attribute1 can be named foobar or id or attribute335...

  • How do I use a Lambda expression to sort INTEGERS inside a object?

    - by punkouter
    I have a collection of objects and I know that I can sort by NAME (string type) by saying collEquipment.Sort((x, y) = string.Compare(x.ItemName, y.ItemName)); that WORKS. But I want to sort by a ID (integer type) and there is no such thing as Int32.Compare So how do I do this? This doesnt work collEquipment.Sort((x, y) = (x.ID < y.ID); //error I know the answer is going to be really simple. Lambda expressions confuse me.

  • books about Firewall development

    - by VP
    Hi, i was just asked today, but i couldn't answer precisely so that's why i'm asking here :-) There is any book about Firewall design and implementations (Unix environment and C)? For sure, i could recommend TCP/IP books, and what i did, but there is some design decisions, that are not related with TCP/IP. For sure, i said about the netfilter/iptables (RTFSC) but as well we cannot assume that the netfilter/iptables is the best approach since we don't have too many baselines (ok, we could compare it with PF, but again, read source code to understand design decisions is not always the best way). So if anybody knows a book about this theme, please shoot it!

  • Implementing a live voting system

    - by Will Eddins
    I'm looking at implementing a live voting system on my website. The website provides a live stream, and I'd like to be able to prompt viewers to select an answer during a vote initiated by the caster. I can understand how to store the data in a mySQL database, and how to process the answers. However: How would I initially start the vote on the client-side and display it? Should a script be running every few seconds on the page, checking another page to see if a question is available for the user? Are there any existing examples of a real-time polling system such as what I'm looking at implementing?

  • Math Mod Containing Numbers

    - by TheDarkIn1978
    i would like to write a simple line of code, without resorting to if statements, that would evaluate whether a number is within a certain range. i can evaluate from 0 - Max by using the modulus. 30 % 90 = 30 //great however, if the test number is greater than the maximum, using modulus will simply start it at 0 for the remaining, where as i would like to limit it to the maximum if it's past the maximum 94 % 90 = 4 //i would like answer to be 90 it becomes even more complicated, to me anyway, if i introduce a minimum for the range. for example: minimum = 10 maximum = 90 therefore, any number i evaluate should be either within range, or the minimum value if it's below range and the maximum value if it's above range -76 should be 10 2 should be 10 30 should be 30 89 should be 89 98 should be 90 23553 should be 90 is it possible to evaluate this with one line of code without using if statements?

  • ModalPopupExtender doesn't work on IE6 frame layout

    - by Joe
    I'm using a "frame" layout similar to the one in this excellent answer: a div #top at the top of the page, a div#left on the left, and a div #main with the main content. The #top and #left divs contain navigation menus. Now I want to use a popup div using the AjaxControlToolkit ModalPopupExtender inside the content (#main) div. This works fine on IE8 (where #top, #left, #main all have position:fixed), but when I run it on IE6, the modal background only covers the #main div - I need it to cover the whole of the page including the #top and #left navigation divs. Looking at the script for ModalPopupExtender, it appears to be searching up the parent hierarchy until it finds a parent with position relative or absolute. And in the IE6 rendering, the #main div has position:absolute because position:fixed is not supported, which I guess explains what is happening. Any suggestions for the best/easiest way to get this working properly on IE6? Ideally without modifying the ModalPopupExtender code, but I'll do this if I have to and it's the best solution.

  • Get the identity value from an insert via a .net dataset update call

    - by DeveloperMCT
    Here is some sample code that inserts a record into a db table: Dim ds As DataSet = New DataSet() da.Fill(ds, "Shippers") Dim RowDatos As DataRow RowDatos = ds.Tables("Shippers").NewRow RowDatos.Item("CompanyName") = "Serpost Peru" RowDatos.Item("Phone") = "(511) 555-5555" ds.Tables("Shippers").Rows.Add(RowDatos) Dim custCB As SqlCommandBuilder = New SqlCommandBuilder(da) da.Update(ds, "Shippers") It inserts a row in the Shippers Table, the ShippersID is a Indentity value. My question is how can i retrieve the Identity value generated when the new row is inserted in the Shippers table. I have done several web searches and the sources I've seen on the net don't answer it speccifically or go on to talk about stored procedures. Any help would be appreciated. Thanks!

    im working on a Windows Phone 7 Application that communicates with a Azure hosted WCF service. Everything works fine in communication and so on. But i want to handle the situation when the Service is not online. Now the WP7 App has a main screen with a login. After clicking the "Login" button the Application sends the credentials to the WCF Service which communicates with a Database. And now my question is, is there a way to get the online/offline state of the WCF Service? So i could give feedback to the user and the application wouldnt crash (: Thx alot for any answer!

  • Dynamically load a type from an external assembly

    - by Water Cooler v2
    From managed code, how do I load a managed type from another assembly at runtime, assuming the calling code does not have a static reference to the assembly? To clarify, let's say I have class Lib in Lib.cs compiled into Lib.dll. I want to write a class Foo in a separate assembly called Foo.dll, that does not have a reference to Lib.dll statically, but instead loads Lib.dll and then reflects on for the presence of the class Lib and then calls a method on it. Sorry for such an obvious question on Reflection. I figure it'll take much lesser time to get the answer on a forum that to read a few articles.

  • Is there a Java unit-test framework that auto-tests getters and setters?

    - by Michael Easter
    There is a well-known debate in Java (and other communities, I'm sure) whether or not trivial getter/setter methods should be tested. Usually, this is with respect to code coverage. Let's agree that this is an open debate, and not try to answer it here. There have been several blog posts on using Java reflection to auto-test such methods. Does any framework (e.g. jUnit) provide such a feature? e.g. An annotation that says "this test T should auto-test all the getters/setters on class C, because I assert that they are standard". It seems to me that it would add value, and if it were configurable, the 'debate' would be left as an option to the user.

  • Calling consecutive java tasks in a shell script

    - by Bigtwinz
    Hi all, This may be a rudimentary question but the answer was not readily available. I'd like to create a shell script that calls 3 tasks consecutively, but wait till the previous task is complete. Like so: a. call first Java program via ant b. call third party Java application c. call third Java program via ant I'm wondering if there is a way to check and ensure a. is done before b. is called and same for b. and c. thanks

  • How many databases to support eCommerce?

    - by Terry Lorber
    I have a system with two databases, one that the customer-facing website uses, the second that is used by the "backroom" order-fulfillment system. I've been asked to run queries from the website to the backroom system. I'd rather not, it seems risky to allow web-based request to run unheeded on the internal system. Additionally, this means opening up routing in the firewall to allow external connections to the internal server. What's the best practice for eCommerce? Run the entire company off of one database? Or individual databases for each system, and middleware to connect them? Sometimes it might be necessary for the web application to pull date from the internal system, but not based on an HTTP request from the internet. I'm sure the best answer is "it depends!" So, if people have a rule of thumb for when to use middleware and when not to, I'd like to here it.

  • What do you tell people your profession is? [closed]

    - by user110296
    My technical title is Member of the Technical Staff, and like you most of you, I design/write code for a living. I can never decide what to answer when someone asks what I do for a living? Software Developer? Software Engineer? [Kernel] Programmer? Computer Scientist? These all seem to have various bad connotations. I guess I like Software Engineer the best, but unfortunately this term has been coopted by people who don't actually code. I made the mistake of taking a 'Software Engineering' class, and realized that I definitely don't want to be associated with people who major in this. Probably this is too subjective, so feel free to community wiki it or whatever, but I think it is a valid question and I would like to hear what others have decided on and their reasoning.

  • Can you pass _POST variables from 1 server to another?

    - by Dr. DOT
    I have a web form on an IIS server (has no PHP). I have a PHP script on a LAMP server. My _POST var array is coming up empty on the LAMP server. My suspicion is I cannot pass POST vars from 1 server to another but I would like to have that confirmed. Does anyone know the answer to this? If that's the case then I know I need to with use _GET vars in the URL's Query String or set a cookie (which I can do because both servers are config'd with the domain name). Thanks for your help.

  • Differences between Ruby on Rails versions? Which should I use?

    - by Stephen Kellett
    I first used Rails when it was not so well known about, in 2005. I did some experimental work with it but it has languished due to lack of time. I'm now thinking of persuing the original idea again (with a new implementation) and when researching the latest Ruby and Ruby-on_Rails versions I see Ruby 1.9.2 and a Rails 3.0 beta. I haven't managed to find a concise description of the differences between any of the Rails major versions. I have looked on the official Rails site and a few others as well. No joy. Maybe i'm looking in the wrong places or for the wrong thing? My project isn't commercial in nature (it's a hobby thing) so the beta nature of Rails 3.0 doesn't put me off. I'd just like to know what the differences are. Can anyone explain please? If it makes any odds to the answer, I'll be working on a Linux box and/or a Windows box.

  • Define a class dynamically?

    - by Pekka
    Is there a way to dynamically and conditionally create a class definition in PHP, i.e. if (condition matches) include file containing class definition else class myclass extends ancestor_class { .................... } without eval()? My background is the accepted answer to this question. I am looking for the best way to build a untouchable core library, with user-defined empty classes extending the core library if necessary. I want to create the final class definition "on the fly" if there is no user-defined empty class for a certain ancestor class.

  • Converting code to perl sub, but not sure I'm doing it right

  • Adding on touch event to images inside gridview

    - by Steve
    I have a gridview where each item has a image and a textview (an app), i added the onItemClick to the gridview in order to launch the app, i also removed the orange selection and made selector in xml so when pressed the text would change to grey and on release it would return to white. My problem is that i need the image to apply an alpha value when pressed and restore the previous alpha on release i tested a lot of ways and none did worked correctly. I came close with the updated answer from the autor of the question: How to set alpha value for drawable in a StateListDrawable?, but some how the state pressed never gets called, i don´t know if this is because i am using the onitemClick to launch the app or not. Also i since i can´t define the alpha on imageview xml i don´t know what else to do Any help will be appreciated

  • How do I attach an event handler to the document or window in GWT?

    - by Raph Levien
    In a GWT app centered around a canvas, I'm having trouble keeping focus directed in the right place - particularly for keyboard shortcuts. For now, I've wrapped the canvas in a FocusPanel, but that causes the canvas to not respond to the RequiresResize protocol, because FocusPanel does not plumb that. A second (related, I think) problem is that the FocusPanel is not getting Ctrl-A keypress events at all (tested on Mac Chrome). I can get Ctrl-Z and other keys (such as arrows) just fine. In a pure JavaScript world, I think the best answer to this would be to attach mouse and key handlers to the document or window object (I'm not positive which is better). However, I don't see an obvious way to do this in GWT - in particular, the Document and Window classes lack methods for attaching these kind of event handlers? Anyone know how to do it, or, perhaps, to solve the more general problem of keeping focus on an appropriate widget able to handle keyboard shortcuts?
