  • WxWidgets custom events

    - by Klaus
    Hello, I'm trying to use a custom event in my WxWidgets C++ application, like described here. In the constructor of my wxApp: Connect(wxID_ANY, wxCommandEventHandler(APP::OnMyEvent)); Then the function that should catch the event: void APP::OnMyEvent(wxCommandEvent& event) { exit(0); //testing } Finally, to test it: wxCommandEvent MyEvent(wxEVT_COMMAND_BUTTON_CLICKED); wxPostEvent(this, MyEvent); I launch the thing...but it seems that the event is not posted or not caught. Does someone understand this behaviour ?

  • Database application using MVC paradigm

    - by Andrei K.
    In classic Delphi database application we have a form, a set of data-aware visual controls connected to TDataSets via TDataSources. If one wants to design database application using MVC model, where to place TDataSet components? Should they stay on form and therefore be a part of View? Or should they be encapsulated inside some Model object? If the latter how they could be bound to visual components?

  • How to handle Clean URIs in Classic ASP using PATH_INFO?

    - by Mario
    I'm trying to handle Clean URIs in a Classic ASP application. In PHP, I was able to use URIs like http://example.com/index.php/foo/bar/baz and have /foo/bar/baz available in the PATH_INFO environment variable. (I usually add a rewrite rule so I do not need the index.php segment) However, I don't seem to be able to mimic this in Classic ASP. If I try http://example.com/index.asp/foo/bar/baz, I get a 404 error. Is there a way to add a path after the index.asp segment and get the PHP like behaviour in ASP? Note: I'm currently using the workaround of rewriting URLs of the form: http://example.com/foo/bar/baz/ to index.asp?path=/foo/bar/baz since I can't seem to get index.asp/foo/bar/baz to work.

  • iPad javascript scrolling

    - by davids
    I'd like to get the same behaviour of the native javascript scrollTo function in iPad, just attaching a function to the swipe event and scrolling the content a specific number of pixels. That doesn't work in iPad using scrollTo or several different jquery plugins, like scrollTo or iScroll. I think I'm having problems because I'm working with an iframe, as I have another html document in it, with its body divided in columns, but I'm just showing the first one. The point of all this is that, after swiping, it should show the next/prev column, and I tried scrolling the iframe window or the inner's html body, which actually works in chrome, but it doesn't in iPad.

  • The whole site is blocked while one page is waiting for blocking operation (PHP, ASP.NET). Why?

    - by artvolk
    Good day! I've found interesting behaviour for both LAMP stack and ASP.NET. The scenario: There is page performing task in 2-3 minutes (making HttpWebRequest for ASP.NET and curl for PHP). While this page is processed all other requests to this virtual host from the same browser are not processed (even if I use different browsers from one machine). I use two pages written in PHP and C#. I've tested with Apache+PHP in both mod_php and fast_cgi modes on Windows and Debian. For ASP.NET I use IIS6 (with dedicated app pool for this site and with default app pool) and IIS7 in integrated mode. I know that it is better to use async calls for such things, but I'm just curious why single page blocks the entire site and not only the thread processing the request? Thanks in advance!

  • How to override inner class methods if the inner class is defined as a property of the top class

    - by Maddy
    I have a code snippet like this class A(object): class b: def print_hello(self): print "Hello world" b = property(b) And I want to override the inner class b (please dont worry about the lowercase name) behaviour. Say, I want to add a new method or I want to change an existing method, like: class C(A): class b(A.b): def print_hello(self): print "Inner Class: Hello world" b = property(b) Now if I create C's object as c = C(), and call c.b I get TypeError: 'property' object is not callable error. How would I get pass this and call print_hello of the extended inner class? Disclaimer: I dont want to change the code for A class.

  • asynchronous method executing

    - by alexeyndru
    I have a delegate method with the following tasks: get something from the internet (ex: some image from a web site); process that image in a certain way; display the result in a subview ; getting the image takes some time, depending on the network's speed so the result of its processing is displayed in the subview after that little while. my problem: during the time between getting the image and showing the result the device looks unresponsive. any attempt to put some spinner, or any other method which is called inside this main procedure has no effect until the result is processed. how should I change this behaviour? I would like to put a big spinner during that waiting time. thank you.

  • Which network protocol to use for lightweight notification of remote apps?

    - by Chris Thornton
    I have this situation.... Client-initiated SOAP 1.1 communication between one server and let's say, tens of thousands of clients. Clients are external, coming in through our firewall, authenticated by certificate, https, etc.. They can be anywhere, and usually have their own firewalls, NAT routers, etc... They're truely external, not just remote corporate offices. They could be in a corporate/campus network, DSL/Cable, even Dialup. Client uses Delphi (2005 + SOAP fixes from 2007), and the server is C#, but from an architecture/design standpoint, that shouldn't matter. Currently, clients push new data to the server and pull new data from the server on 15-minute polling loop. The server currently does not push data - the client hits the "messagecount" method, to see if there is new data to pull. If 0, it sleeps for another 15 min and checks again. We're trying to get that down to 7 seconds. If this were an internal app, with one or just a few dozen clients, we'd write a cilent "listener" soap service, and would push data to it. But since they're external, sit behind their own firewalls, and sometimes private networks behind NAT routers, this is not practical. So we're left with polling on a much quicker loop. 10K clients, each checking their messagecount every 10 seconds, is going to be 1000/sec messages that will mostly just waste bandwidth, server, firewall, and authenticator resources. So I'm trying to design something better than what would amount to a self-inflicted DoS attack. I don't think it's practical to have the server send soap messages to the client (push) as this would require too much configuration at the client end. But I think there are alternatives that I don't know about. Such as: 1) Is there a way for the client to make a request for GetMessageCount() via Soap 1.1, and get the response, and then perhaps, "stay on the line" for perhaps 5-10 minutes to get additional responses in case new data arrives? i.e the server says "0", then a minute later in response to some SQL trigger (the server is C# on Sql Server, btw), knows that this client is still "on the line" and sends the updated message count of "5"? 2) Is there some other protocol that we could use to "ping" the client, using information gathered from their last GetMessageCount() request? 3) I don't even know. I guess I'm looking for some magic protocol where the client can send a GetMessageCount() request, which would include info for "oh by the way, in case the answer changes in the next hour, ping me at this address...". Also, I'm assuming that any of these "keep the line open" schemes would seriously impact the server sizing, as it would need to keep many thousands of connections open, simultaneously. That would likely impact the firewalls too, I think. Is there anything out there like that? Or am I pretty much stuck with polling? TIA, Chris

  • Will PHP Die In Web Page Development World?

    - by Morgan Cheng
    I know that PHP is still the most popular web programming language in the world. This question just want to bring some of my concerns about PHP. PHP is naturally bound to C10K problem. Since PHP (generally run in Apache) cannot be event-driven or asynchronous, each HTTP request will occupy at least one thread or process. This makes it resistant to be more scalable. Currently, a lot of web sites (like Facebook) with high performance and scalability still depends on PHP in their front end servers. I suppose it is due to legacy reason. Is it possible that PHP will be replaced by language more suitable for C10K?

  • Max number of web methods?

    - by Rippo
    Guys I have a web service in asp.net 2.0 that has 234 methods. It seems that when I add another method the site does not compile in VS2005 until I remove one first. I get a message saying that the new method I just added does not exist in a file that belongs in the Microsoft.Net/.../Temporary Files directory. I have restarted IIS, closed down VS2005, removed all files from this temp directory but to no avail. The only way to get the code to compile is to remove another one so as to keep 234 methods.... I can consistency replicate this behaviour so it cannot be my code. Now I know this seems strange but it is true! One other strange thing is that exactly 100 of the method names begin with the word GetXXXyyyZZZ Has anyone else experienced problems with the maximum number of methods that are allowed in a web service? Many Thanks

  • fluent nhibernate not caching queries in asp.net mvc

    - by AWC
    I'm using a fluent nhibernate with asp.net mvc and I not seeing anything been cached when making queries against the database. I'm not currently using an L2 cache implementation. Should I see queries being cached without configuring an out of process L2 cache? Mapping are like this: Table("ApplicationCategories"); Not.LazyLoad(); Cache.ReadWrite().IncludeAll(); Id(x => x.Id); Map(x => x.Name).Not.Nullable(); Map(x => x.Description).Nullable(); Example Criteria: return session .CreateCriteria<ApplicationCategory>() .Add(Restrictions.Eq("Name", _name)) .SetCacheable(true); Everytime I make a request for an application cateogry by name it is hitting the database is this expected behaviour?

  • Grading your programming ability?

    - by Farstucker
    I understand this is a subjective question and very likely could be closed, and although there is no right or wrong answer I do believe its a legitimate question. At what point do you no longer consider someone a beginner (ie knowledge of loops, encapsulation, instantiation), an intermediate (design patterns, reflection, delegates, interfaces) or an expert (architecture, multi-threadding). My rational for asking such a question is two-fold, first, when do I stop labeling my questions as beginner and during a job interview how should I categorize myself?

  • Pro's and Con's of unit testing after the fact.

    - by scope-creep
    I have a largish complex app around 27k lines. Its essentially a rule drive multithreaded processing engine, without giving too much away Its been partially tested as it's been built, certain components. Question I have, is what is the pro's and con's of doing unit testing on after the fact, so to speak, after its been implemented. It is clear that traditional testing is going to take 2-3+ months to test every facet, and it all needs to work, and that time is not available really. I've done a fair bit of unit testing in the past, but generally it's been on desktop automation or LOB apps, which are fairly simple. The app is itself is highly componentized internally, interface driven really. I've not decided on what particular framework to use. Any advice would be appreciated. What say you.

  • How to define colors in XCodes' Interface Builder?

    - by favo
    Hi, I would like to copy colors between elements in the interface builder or define them using RGB values. I.e. copy the background color of a button to another button without duplicating the button. Or: Enter an exact RGB code using the interface builder. Currently I can do this only programmatically but the interface builder is meant to design the GUI, so there must be such possibilities. Thank you all in advance for your answers.

  • Morfik - suitability for medium-scale web enterprise applications

    - by MaikB
    I'm investigating technologies with which to develop a medium-scale (up to 100 or 200 simultaneous users) database-driven web application, and someone suggested Morfik. However, outside of the Morfik company I can find practically zero community support - no active blogs, no tutorials, no videos, no books - and this is of some concern (especially when compared to C# / ASP.NET / nHibernate etc support). Deciding between Morfik (untried and not used widely AFAIK) and the other technologies I mentioned (tried, tested, used widely) is becoming a critical issue for my company. Has anyone had success using Morfik in these kind of circumstances? What kind of performance did you achieve?

  • The use of Javascript - stats?

    - by Luke
    I am looking at redesigning my website and was wondering if I could get some opinions. I know that the rule is usually to design with users without JS first and foremost, but having looked at the stats, it appears 95% of the users online have JS enabled. Would you recommend designing the website using JS and not bothering about people without it?

  • Hibernate: how to maintain insertion order

    - by jwaddell
    I have a list of entities where creation order is important, but they do not contain a timestamp to use for sorting. Entities are added to the end of the list as they are created so they will be ordered correctly in the list itself. After persisting the list using Hibernate the entities appear in the database table in the order that they were created. However when retrieving the list using a new Hibernate session the list is now in reverse order of insertion/creation. Is this expected behaviour? Is there any way to retrieve the list in the same order as it appears in the table? The primary key is a UUID, and the list of entities should always have been created on the same IP address and JVM. This mean sorting by UUID is a possibility but I'd rather not make assumptions. Another possibility is if the list is guaranteed to always come out in reverse order I could always just work through it backwards.

  • What is the best method for implementing mouse wheel activity in Delph1 VCL forms?

    - by Brian Frost
    As a long time user of Delphi 7, I've rolled my own mouse wheel handling in a few controls but lately I've noticed that some recent applications only need the mouse cursor to be placed over a control (e.g a list box or tree view) for the mouse wheel activity to cause that control to scroll. This feels nice (as opposed to having to click focus a control before it responds to the wheel. Now I've moved to Delphi 2010 I'm wondering what is the 'correct' behaviour? And what can I use in Delphi that avoids me having to bodge this with my own solutions now? Thanks.

  • jQuery Ajax: Copy - Paste thingy

    - by tsiger
    Hi everyone, I have a form where a check an input field for its value and then i do an Ajax call using the typewatch plugin ( a small little thing which detects that the user has stopped typing after a predefined interval ). It works great. As this field is a "coupon discount" in an order form, the value could be entered by copy pasting the "coupon code" from an email or something. It also works with Ctrl+C - Ctrl+V for Copy and paste but not when a user selects the text with the mouse, clicks copy from the context menu and then paste from this menu. Is there a way in jQuery to check for this kind of behaviour in jQuery somehow?
