  • Java Imaging Framework

    - by Prabhakar
    Is there any Open source or Commercial Java frameworks for doing image operations such as converting the images from one format to other and scaling the images etc. There should be no installation.Set of jars that are in classpath that will do the job. I have looked into the java-image-scaling library but it is having issues. Thanks in advance.

  • Looking to display a text RSS feed as Windows 7 desktop/background

    - by Matt
    I'd like to display an RSS feed (updating dynamically of course) on my Windows 7 desktop. The posts I've read about Windows 7 RSS backgrounds are all about displaying various background images delivered via RSS. What I'm looking for would be similar to the Windows XP/95 Active Desktop feature which allowed for web pages to be presented on the desktop background.

  • How to impelement messaging services in a website?

    - by Alex
    There's a website which currently has only web interfaces for all the users. However, new requirement has emerged which says that there is a need in providing an alternative interface for a certain group of website users who want to regularly receive pushed notifications(messages) that would inform them about new events(news) in their field of interest. What sort of interface would it be?Is it all about using a MOM(message-oriented middleware) like JMS and deploying it withing an application server on a website using publish/subscribe model?Is it the correct way how to meet these sort of requirements?And if it's not a web-based interface,would kind of interface would it be then for the users? Thanks

  • Text overflowing floated div

    - by James Hatton
    I have a problem with a fluid layout I am attempting to create. I was wondering why I am not able to get overflow:hidden to work on the left menu text on this site. As you can see here, I have labelled in blue, the text which I would like contained within the left menu div, although it overflows and pushes the rest of the site down with it. Please see here for a JS Bin: http://jsbin.com/OcoJEpe/2/edit?html,css,output Thanks for your help. James.

  • iPhone Text entry with completion and DONE button (not search)

    - by Adam Jack
    Using iPhone SDK 3.0, I wish to allow text entry with (optional) completion options that appear as typing is occurring, i.e. also allowing freeformat entry. As such I am using a UISearchBar (which has the text change events) and a UISearchDisplayController to present options. The problems is I want the DONE button to say DONE and not SEARCH, however I cannot find a way to set that. Clearly I feel I am missing something, or Interface Builder of the SDK API would have some property to set. I have seen other apps (in the store) that have achieved the result I want (free format entry, completion, DONE button) so maybe there is an alternative approach I am missing. Thanks in advance for any pointers.

  • Dropdownlist post in ASP.NET MVC3 and Entity Framework Model

    - by Josh Blade
    I have 3 tables: RateProfile RateProfileID ProfileName Rate RateID RateProfileID PanelID Other stuff to update Panel PanelID PanelName I have models for each of these. I have an edit page using the RateProfile model. I display the information for RateProfile and also all of the Rates associated with it. This works fine and I can update it fine. However, I also added a dropdown so that I can filter Rates by PanelID. I need it to post back on change so that it can display the filtered rates. I'm using @Html.DropDownList("PanelID", (SelectList)ViewData["PanelDropDown"], new { onchange = "$('#RateForm').submit()" }) for my dropdownlist. Whenever it posts back to my HttpPost Edit method though, it seems to be missing all information about the Rates navigation property. It's weird because I thought it would do exactly what the input/submit button that I have in the form does (which actually passes the entire model back to my HttpPost Edit action and does what I want it to do). The panelID is properly being passed to my HttpPost Edit method and on to the next view, but when I try to query the Model.Rates navigation property is null (only when the post comes from the dropdown. Everything works fine when the post comes from my submit input). Get Edit: public ActionResult Edit(int id, int panelID = 1) { RateProfile rateprofile = db.RateProfiles.Single(r => r.RateProfileID == id); var panels = db.Panels; ViewData["PanelDropDown"] = new SelectList(panels, "PanelID", "PanelName", panelID); ViewBag.PanelID = panelID; return View(rateprofile); } HttpPost Edit: [HttpPost] public ActionResult Edit(RateProfile rateprofile, int panelID) { var panels = db.Panels; ViewData["PanelDropDown"] = new SelectList(panels, "PanelID", "PanelName", panelID); ViewBag.PanelID = panelID; if (ModelState.IsValid) { db.Entry(rateprofile).State = EntityState.Modified; foreach (Rate dimerate in rateprofile.Rates) { db.Entry(dimerate).State = EntityState.Modified; } db.SaveChanges(); return View(rateprofile); } return View(rateprofile); } View: @model PDR.Models.RateProfile @using (Html.BeginForm(null,null,FormMethod.Post, new {id="RateForm"})) { <div> @Html.Label("Panel") @Html.DropDownList("PanelID", (SelectList)ViewData["PanelDropDown"], new { onchange = "$('#RateForm').submit()" }) </div> @{var rates= Model.Rates.Where(a => a.PanelID == ViewBag.PanelID).OrderBy(a => a.minCount).ToList();} @for (int i = 0; i < rates.Count; i++) { <tr> <td> @Html.HiddenFor(modelItem => rates[i].RateProfileID) @Html.HiddenFor(modelItem => rates[i].RateID) @Html.HiddenFor(modelItem => rates[i].PanelID) @Html.EditorFor(modelItem => rates[i].minCount) @Html.ValidationMessageFor(model => rates[i].minCount) </td> <td> @Html.EditorFor(modelItem => rates[i].maxCount) @Html.ValidationMessageFor(model => rates[i].maxCount) </td> <td> @Html.EditorFor(modelItem => rates[i].Amount) @Html.ValidationMessageFor(model => rates[i].Amount) </td> </tr> } <input type="submit" value="Save" /> } To summarize my problem, the below query in my view only works when the post comes from the submit button and not when it comes from my dropdownlist. @{var rates= Model.Rates.Where(a => a.PanelID == ViewBag.PanelID).OrderBy(a => a.minCount).ToList();}

  • How do URL shortening services make money?

    - by Rakesh Juyal
    Yesterday i got to know about one more URL shortening service Saf.li. I think there are hundreds of websites offering such service. I always wonder how do such sites make money? After all they need money to host their data and code. Also, i really don't understand why techcrunch said this:- http://techcrunch.com/2009/03/30/if-bitly-is-worth-8-million-tinyurl-is-worth-at-least-46-million/ Is there any one who can explain me this?

  • How strict to be when using Qt framework?

    - by toffeehoops
    I'm building a Qt application that needs to use libssh, a SSH client library. libssh (understandably) performs its own network connections, however Qt has its own infrastructure for network connections (QTcpSocket etc). Should I worry about these differences? Should I be trying to make libssh make network connections via QTcpSocket... Or if it works fine on the platforms I'm targeting, is that good enough?

  • translate by replacing words inside existing text

    - by Berry Tsakala
    What are common approaches for translating certain words (or expressions) inside a given text, when the text must be reconstructed (with punctuations and everythin.) ? The translation comes from a lookup table, and covers words, collocations, and emoticons like L33t, CUL8R, :-), etc. Simple string search-and-replace is not enough since it can replace part of longer words (cat dog ? caterpillar dogerpillar). Assume the following input: s = "dogbert, started a dilbert dilbertion proces cat-bert :-)" after translation, i should receive something like: result = "anna, started a george dilbertion process cat-bert smiley" I can't simply tokenize, since i loose punctuations and word positions. Regular expressions, works for normal words, but don't catch special expressions like the smiley :-) but it does . re.sub(r'\bword\b','translation',s) ==> translation re.sub(r'\b:-\)\b','smiley',s) ==> :-) for now i'm using the above mentioned regex, and simple replace for the non-alphanumeric words, but it's far from being bulletproof. (p.s. i'm using python)

  • vectorization of a text file

    - by Fox
    I am trying to implement vectorization of a text file...I have created a dictionary (Unique words in all the documents) ... Which is the best way to implement this in java? For example - My dictionary has the following words - {w1, w2, w3, w4} And I have 2 documents each having subset of the words in the vocabulary. I need to write to a text file the matrix in the form -- 1,3,4,0 0,0,2,1 Here each row represents a document and the values represent the occurrence of each word in the document. Can you suggest me the most efficient way to implement this in Java?

  • Entity Framework 4 / POCO - Where to start?

    - by Basiclife
    Hi, I've been programming for a while and have used LINQ-To-SQL and LINQ-To-Entities before (although when using entities it has been on a Entity/Table 1-1 relationship - ie not much different than L2SQL) I've been doing a lot of reading about Inversion of Control, Unit of Work, POCO and repository patterns and would like to use this methodology in my new applications. Where I'm struggling is finding a clear, concise beginners guide for EF4 which doesn't assume knowledge of EF1. The specific questions I need answered are: Code first / model first? Pros/cons in regards to EF4 (ie what happens if I do code first, change the code at a later date and need to regenerate my DB model - Does the data get preserved and transformed or dropped?) Assuming I'm going code-first (I'd like to see how EF4 converts that to a DB schema) how do I actually get started? Quite often I've seen articles with entity diagrams stating "So this is my entity model, now I'm going to ..." - Unfortunately, I'm unclear if they're created the model in the designer, saved it to generate code then stopped any further auto-code generation -or- They've coded (POCO)? classes and the somehow imported them into the deisgner view? I suppose what I really need is an understanding of where the "magic" comes from and how to add it myself if I'm not just generating an EF model directly from a DB. I'm aware the question is a little vague but I don't know what I don't know - So any input / correction / clarification appreciated. Needless to say, I don't expect anyone to sit here and teach me EF - I'd just like some good tutorials/forums/blogs/etc. for complete entity newbies Many thanks in advance

  • WCF REST based services authentication schemes

    - by FlySwat
    I have a simple authentication scheme for a set of semi-public REST API's we are building: /-----------------------\ | Client POST's ID/Pass | | to an Auth Service | \-----------------------/ [Client] ------------POST----------------------> [Service/Authenticate] | /-------------------------------\ | Service checks credentials | [Client] <---------Session Cookie------- | and generates a session token | | | in a cookie. | | \-------------------------------/ | [Client] -----------GET /w Cookie -------------> [Service/Something] | /----------------------------------\ | Client must pass session cookie | | with each API request | | or will get a 401. | \----------------------------------/ This works well, because the client never needs to do anything except receive a cookie, and then pass it along. For browser applications, this happens automatically by the browser, for non browser applications, it is pretty trivial to save the cookie and send it with each request. However, I have not figured out a good approach for doing the initial handshake from browser applications. For example, if this is all happening using a AJAX technique, what prevents the user from being able to access the ID/Pass the client is using to handshake with the service? It seem's like this is the only stumbling block to this approach and I'm stumped.

  • Access Services and SharePoint 2010 - Need Info

    - by Mayo
    I've been asked to research the ability to publish Access solutions directly to SharePoint as demonstrated in the demo below. http://channel9.msdn.com/shows/Access/Microsoft-Access-2010-Demo/ I'm going to keep searching via Google / Bing - but I thought I'd check here to see if anyone has any good links to information on this feature. At first glance it seems like I'm getting alot of brief blog entries with links to the SP2009 conference or to the above video.

  • How to improve long text readability in Chrome?

    - by amiregelz
    I need to start reading The TCP/IP Guide. I have to admit that compared to other informative guides/tutorials/articles out there, this guide isn't so cluttered. However, I still find it a little bit hard to read, especially when reading for several hours. I don't know if it's the font, the contrast or the spacing, but this is why I've always preferred learning from books rather than from the internet. What can I do to make this guide more readable? I am reading it on Google Chrome.

  • Vlookup to retrieve an ID from table using text match

    - by Federico Giust
    I've got an excel spreadsheet where I would normally use a VLOOKUP. In this case I need to find the ID of the record when comparing email addresses, so the email address is the unique id here. For example on sheet 1 A B C D Person Id | Family Name | First Name | Email #N/A | Doe | John | [email protected] On Sheet 2 A B C D Person Id | Family Name | First Name | Email 12345 | Doe | John | [email protected] Basically on sheet 1 I've got 800 records, on sheet 2 450. I know the 450 are in Sheet 1, so I need to find the ids of those, and put them on sheet 1 where I've got lots more data for each person. What I've tried so far is a VLOOKUP, but I keep getting an error. I'd like to do it with some sort of formula and not using any copy paste and remove duplicates. Any ideas?

  • Where I can download the REAL Full .Net Framework 4 Standalone Installer?

    - by Click Ok
    I found that links: Microsoft .NET Framework 4 (Web Installer) Microsoft .NET Framework 4 (Standalone Installer) Microsoft .NET Framework 4 Client Profile (Standalone Installer) Note that (2) the size is 48.0 MB and the (3) the size is 41.0 MB. It's not the REAL .Net 4 Full Standalone. :( I want that installer in a usb pen drive because my app need of features of .Net 4 Full Framework (like MSBuild) and I will install in a enviroment without Internet access. PS: I tested the (2) and really is the Client Profile with another name... :(

  • Use Excel Color Scale Formatting with Text

    - by stumpylog
    I use Excel sheets to track the status of tasks through a set of discrete statuses. I'd like to be able to format these automatically, with the start being red, the end being green and progressing through the combination colors in the middle. Status1 (Red) Status2 (More Red than Green) Status3 (More Green than Red) Status4 (Green) The "Color Scales" option under Conditional Formatting seems like it could be made to work, but it wants numbers. So, my question, can it be done? Using conditional formatting or other formulas to achieve the desired affect?

  • Make input field background image disappear after text is inputted

    - by aslum
    I'd like to make the background image for my input field disappear once the user has typed any amount of text in it. Is there a simple way to do that in javascript? I can get it so the bg disappears while the field is focused, but then it returns once they move on to the next field. HTML: Call me at <input name="phone" type="text" class="phone-field" id="phone"> CSS: .form input { background-color:transparent; } .form input:focus { background-color:#edc; background-image:none; } input.phone-field { background-image: (url/images/phonebg.png); background-repeat: no-repeat; background-position: left 1px; }

  • Ajax Rich Internet Application framework for Linux + Firefox _AND_ iPhone consumption

    - by Maroloccio
    For a zero-budget (e.g. University) project we need to build a rich web UI for Firefox and iPhone clients. Firm requirement: all technologies to be free and open-source. Nice-to-have: all development to be done in Java/Eclipse. I generally like the Google's AppEngine + GWT combo but this project will require much more interactivity than what's in GWT 2.0. Something along the lines of: http://www.smartclient.com/smartgwt/showcase/. I know trusty plain ol' GWT won't cut it this time. Straight question: is there something that does the sort of thing that SmartGWT does and works really well on Safari/iPhone? I would say the mobile experience is even more important for this project than the desktop one. Optional question: perhaps this is not the best route to go at all? How could we otherwise render a rich UI with such capabilities and interactivity on both screen sizes? Windows, drag-and-drop, advanced tabs, dynamic grids... We don't need to support any other mobile devices. Yet. ;-)
