  • Where are the really high quality and complex Swing components?

    - by jouhni
    Looking at Swing, I have the feeling that it comes with many useful and reasonable atomic components in its core. And when I look at the Web there are hundrets of quickly plugged together components (among them many date/time pickers, pimped lists and tables), which have in common that I could easily write them on my own, if I needed them. When I build big software and come to the point where I need a domain-specific component which is really big, I mostly come to the point where I have to write it on my own, which, due to the point that they are not just plugged together lists and tables, isn't done qickly. So, the question is, why are there no Swing component galleries which contain more than just customized date/time pickers or lists with added tree support. Where are the components which really raise the level of abstraction, or are in best case domain-specific?

  • Automate download of BusinessObjecs Web Intelligence reports

    - by Daren Thomas
    I'm tasked with automating the retrieval of a couple of BusinessObjects Web Intelligence reports and further processing thereof. I have no other means of access to this data (this was the first avenue I followed), so I will have to do some screen scraping. Alas, the interface seems user-only. Grr! Has anyone done this before? Like to share? Also, does anyone know of a good library for automating the web browser? I know there is a python thingy out there that can be used for testing web applications - I need something in .NET though... What is your favorite? PS: I have also checked this thread (automate getting report from webpage), but am hoping for a Web Intelligence specific sollution.

  • CSS/HTML: Highlighting the "full width avaialble" to a list item

    - by JoshuaD
    I'm working on a website for a small law office. In the side-menu, I'm trying to highlight the "current page". I have tried changing the background of the LI, but this doesn't quite do the trick; the list item doesn't spread to the full width of the menu, so it looks bad. Here's a jfiddle. I would like the yellow section to highlight like the pink section is highlighted: filling up the full vertical and horizontal space, not just highlighting the text. Any suggestions on how to do this? I've included the style tag in the html just for example, obviously, and my real solution will be a little different when it's done. But I can't move forward until I figure out how to somehow highlight the entire line.

  • How to use error provider at run time along with associating any control to validate

    - by Shantanu Gupta
    I am trying to create a Validation in a reusable fashion. Purpose: Make the validation control reusable. Error Provider should associate with control passed dynamically and can be set or cleared at run time. When user press OnClick event then all the controls gets validated with their own Error Providers. public bool IsFieldEmpty(ref TextBox txtControl, Boolean SetErrorProvider,string msgToShowOnError) { ErrorProvider EP = new ErrorProvider(); if (txtControl.Text == string.Empty) { if(SetErrorProvider==true) EP.SetError(txtControl, msgToShowOnError); return true; } else { if(SetErrorProvider==true) EP.Clear(); return false; } } Issue: Every time the function is called new errorprovider object gets created which i dont want. Every control should not have more than 1 error provider and i should be able to search it just like as done in asp.net to search for some control on a Page. How can I do this

  • iphone instance / class method issue

    - by user290031
    Hey All, Okay, so I have a viewController method that has some elements created with interface builder and some I coded myself. I created a view in the IB...lets call it viewOne. I created a loop that creates buttons (through code) and places them on a separate view (viewTwo). This is done in a class method. However, I want the view I made to be opened everytime one of the buttons is clicked. So I did: [button addTarget:self action:@selector(woogoo:) forControlEvents:UIControlEventTouchUpInside]; The woogoo class does the following: +(void) woogoo:(id)sender { //back button [self.view addSubview:viewOne] } However, the program crashes when a button is clicked. I did try making woogoo an instance method but it also crashes in this case too. All I want to do is show viewOne when a button is clicked. Any ideas what I can do?

  • How different protocols interact with eachother in Twisted

    - by stsupermouse
    The scenario I want two different protocols interact with each other is as below: A and B is two different protocols. First A will interact with the server and retrieve some values. Only after A finishes retrieving the values , B will start to interact with the server. Now my problem is that is there an elegant way to initial B when A retrieves the values. Currently I just initial B in A's data process function. But i don't think that this is an elegant way. What I mean an elegant way is that the initialization of B is done by a flow controller or something like that, but not another protocol. Is there an elegant way? such using defered or any other things. I'm just new to twisted, not knowing very much about defered.... Thank you very much!

  • Is there any kind of standard for 8086 multiprocessing?

    - by Earlz
    Back when I made an 8086 emulator I noticed that there was the LOCK prefix intended for synchonization in a multiprocessor environment. Yet the only multitasking I know of for the x86 arch. involves use of the APIC which didn't come around until either the Pentiums or 486s. Was there any kind of standard for 8086 multitasking or was it done by some manufacturer specific extensions to the instruction set and/or special ports? By standard, I mean things like: How do you separate the 2 processors if they both use the same memory? This is impossible without some kind of way to make each processor execute a different piece of code. (or cause an interrupt on only one processor)

  • ignore certain buffers using iswitchb

    - by robUK
    Hello, GNU Emacs 23.1 I am using iswitchb. However, when I press c-x b I get a list of buffers. However, I don't want to display one like scratch, Messages, GNU Emacs, etc. Just the buffers I have opened myself. So I am looking for a way to ignore these buffers. This is what I have in my configuration. However, it doesn't ignore the buffers I don't want. Have I done anything wrong? ;; Setup iswitchb to select different buffers, ignore buffers to reduce list (iswitchb-mode 1) (setq iswitchb-buffer-ignore '("*scratch*")) (setq iswitchb-buffer-ignore '("*Messages*")) (setq iswitchb-buffer-ignore '("*GNU Emacs*")) (setq iswitchb-buffer-ignore '("*compilation*")) Many thanks for any suggestions,

  • Documenting a policy based design

    - by academicRobot
    I'm re-working some prototype code into a policy based design in C++, and I'm wondering what the best practice is for documenting the design. My current plan is to document: Policy hierarchy Overview of each policy Description of each type/value/function in each policy I was thinking of putting this into a doxygen module, but this looks like it will be a bit awkward since formatting will have to be done by hand without code to base the doc on (that is, documenting the policies rather than the implementation of the policies). So my questions are: Are there other aspects of the design that should be documented? Are there any tricks to doing this efficiently in doxygen? Is there a tool other than doxygen thats better suited to this? What are some examples of well documented policy based design? This is my first serious attempt at policy based design. I think I have a working grasp of the principles, but whatever naivety I expose in this question is fair game for an answer too.

  • E4X in ActionScript

    - by Brian Genisio
    Hey all, Looking at the E4X implementation in ActionScript, it occurs to me that they had to figure out how to do three things that I am not sure can be done within ActionScript regularly: Properties/Getters prefixed with @: var myAttribute = xmlPerson.@name; Nameless functions for filtering: xmlData.person.(/* predicate */) lambda syntax for predicates: xmlData.person.(@name == "Brian") So here is my question: Are these just one-off capabilities (much like Vector.<>) they put in just for E4X, therefore keeping out of reach for us? Or do we, as ActionScript developers, have access to these features? More specifically, I'd love to get access to the expression tree of that lambda predicate for my own code (not tied to the XML classes in any way). I figured out that this is called the "filter operator"... but I am not sure how to harness it. Not sure I can... since ActionScript does not allow for operator overloading :(

    - by shake
    Well, i need to make simulator for non-deterministic Push-Down Automaton. Everything is okey, i know i need to do recursion or something similar. But i do not know how to make that function which would simulate automaton. I got everything else under control, automaton generator, stack ... I am doing it in java, so this is maybe only issue that man can bump on, and i did it. So if anyone have done something similar, i could use advices. This is my current organisation of code: C lasses: class transit: list -contains non deterministic transitions state input sign stack sign class generator it generate automaton from file clas NPA public boolean start() - this function i am having trouble with Of course problem of separate stacks, and input for every branch. I tried to solve it with collection of objects NPA and try to start every object, but it doesn work :((..

  • jQuery - want to get input value for submit but it gets one and repeats

    - by jquery n00b
    I'm trying to replace all submit buttons with a span so cufon will work. The input still needs to be there so have done some css to hide it and overlay to span on top. My issue is getting the value from the input tag is proving quite diffcult. The code below gets the first input value (being 'search' from the search box at the top of the page, and then puts that value into all the spans, even for buttons that have different values (eg: send). This is a .NET page so the whole page is wrapped in one form tag. Any help is greatly appreciated. jQUERY: jQuery(document).ready( function() { jQuery(".button-wrap input.button").each(function() { var values = jQuery(".button-wrap input").attr('value'); jQuery(this).before("<span class='input-replacer'>" +values+ "</span>"); });

  • openGL ES retina support

    - by Bryan
    I'm trying to get the avTouch sample code app to run on the retina display. Has anyone done this? In the CALevelMeter class, I've tried the following: - (id)initWithCoder:(NSCoder *)coder { if (self = [super initWithCoder:coder]) { CGFloat f = self.contentScaleFactor; if ([self respondsToSelector:@selector(contentScaleFactor)]) { self.contentScaleFactor = [[UIScreen mainScreen] scale]; } f = self.contentScaleFactor; _showsPeaks = YES; _channelNumbers = [[NSArray alloc] initWithObjects:[NSNumber numberWithInt:0], nil]; _vertical = NO; _useGL = YES; _meterTable = new MeterTable(kMinDBvalue); [self layoutSubLevelMeters]; [self registerForBackgroundNotifications]; } return self; } and it sets the contentScaleFactor to "2". Great, that was expected. But then in the layoutSubviews, CALevelMeter frame is still 1/2 of what it should be. Any ideas?

  • Is GAE Really GZipping My Content? Slow Response Times with GAE as CDN

    - by viatropos
    I am testing out Google App Engine as a free Content Delivery Network and it feels like it's taking a long time to serve up my content. Why does this gae page take a say a half a second to download, while your typical stack overflow page downloads much faster even with a ton more content? What am I missing here? All I have done is create an app and uploaded an image according to that tutorial, but content is being served very slowly it seems. Any suggestions? (Not considering Amazon or other CDNs right now, just looking for help with GAE). Note: I am using Safari when I visit those links, maybe safari is causing problems?

  • How to use a variable to specify filegroup in SQL Server

    - by gt
    I want to alter a table to add a constraint during upgrade on a SQL Server database. This table is normally indexed on a filegroup called 'MY_INDEX' - but may also be on a database without this filegroup. In this case I want the indexing to be done on the 'PRIMARY' filegroup. I tried the following code to achieve this: DECLARE @fgName AS VARCHAR(10) SET @fgName = CASE WHEN EXISTS(SELECT groupname FROM sysfilegroups WHERE groupname = 'MY_INDEX') THEN QUOTENAME('MY_INDEX') ELSE QUOTENAME('PRIMARY') END ALTER TABLE [dbo].[mytable] ADD CONSTRAINT [PK_mytable] PRIMARY KEY ( [myGuid] ASC ) ON @fgName -- fails: 'incorrect syntax' However, the last line fails as it appears a filegroup cannot be specified by variable. Is this possible?

  • Examples of mobile frameworks that support AdSense for mobile content ads?

    - by David Sky
    I’ve tried, I really have, to find examples of serving up AdSense for mobile content ads in any of the popular mobile frameworks, but can’t find running webpages with ads, nor tutorials, etc.... I’ve done some iUI work, but would consider jQueryMobile, iWebKit, even sencha-touch if I could find an example that actually displays ads within the framework on an iPhone, iPod touch,etc... I realize there are issues with the HTML adSense generates, but hasn’t anyone found a work-around? Surely some mobile HTML sites must be serving up ads? Links to tutorials would be much appreciated!

  • Having all Views in the Shared folder - works but is throwing "caught exceptions". Performance conc

    - by Scott
    Hi everyone, I have a simple but heavily used app done in VS2010/MVC2. I didn't like having separate folders for each view/controller and so have all the views in the Shared folder. It's working fine but while debugging in VS, I noticed that it's throwing IO "caught exceptions" since it seems to be looking in the [FolderName]/[ViewName] folder before going down to the Shared folder. Again, the app runs fine but I'm concerned that all these "caught exceptions" will have a minor performance impact since they do have a cost in via the CLR. Is there any way I can configure the Routing so that it will only look in the Shared folder? Thanks.

  • How to upload a directory via Grails or Java ?

I would like to define my directory, and upload all files directly. Any ideas ?

  • Adding a red5 app in a multiuser website

    - by Zakaria
    hi everybody, I have an mvc php website where users can publish their public information: http://www.example.com/foobar/profile. Beside this project, based on some red5 samples, I have an application (done with Flex) that sends audio: rtmp://server/sendAudio (very basic but works). I want to create for each subscribed on my website an admin part where can send an audio stream: http://admin.example.com/foobar. And, when someone goes on their public profile, they can listen to the streamed audio: http://www.example.com/foobar/profile). How can I use my red5/flash app dynamically with my php website so that my users can broadcast their proper canal? Do you have some experience to share ? Thank you, Regards.

  • How to configure XMPP to allow all logged in user to see each other and chat with each other?

    - by Nachiket
    Hello guys, I am new to XMPP. I am using Openfire server, and created a console client using Smack library. My usecase: All users anonymous, logged in (In future, website visitors) will be able to see other anonymous, logged-in users. And they can initiate a private chat (one-to-one) with any of them. So, I am able to logged in as Anonymous user, but I am not able to see other Anon / Logged in users (using Roster), because they are not in anon user's roster. So, What should be configuration OR custom=component/code to to achieve this usecase? Do I need to create server component? Any hint? OR It can be done using proper configuration? Cheers

  • animate() not working for opacity in IE

    - by Karthik
    I'm trying to animate a div from 100% opacity to 40% opacity WITHOUT using fadeTo(). I need to use animate(). It works fine in chrome/FF/safari, but in IE, the opacity doesn't animate, it simply changes to that after the animation is done. Happens in IE 7 and 8. I'm doing this: .animate({ width: new_width, top: new_top, left: new_left, padding: new_padding, opacity: 0.4, filter: "alpha(opacity=40)" }, ... it's just not animating the opacity. Any ideas?

  • Pomodoro technique & other ways to increase personal productivity

    - by Jayson
    I recently came across the Pomodoro Technique as a way to increase productivity, get in the zone, and in general feel a sense of accomplishment at setting some short programming goals and achieving them. So far I have enjoyed it and the sense of accomplishment I get after seeing a bunch of short goals add up at the end of the day to a lot of work done on a programming project. What other ideas, similar or not, add a little variety to achieving goals, personal productivity, get in the programming zone, and so forth? What ideas or techniques are expressed formally, such as those in the Pomodoro paper, rather than trite maxims?
