• Get user-inputed file name from JFileChooser Save dialog box

  - by Anya

  This answer to this question may seem obvious, but I'm actually struggling with it quite a bit. I've searched through JFileChooser methods in the API, and I've looked at some of the questions already asked and answered here on stackoverflow. My question is this. In my program, I am to allow the user to type in a file name which I will then use to create a brand new file that I will write on. How do you get the text the user has entered in the textfield next to the label "Save As:" on the Save dialog box provided by JFileChooser? Is there a JFileChooser method that would allow me to get that user-inputed text? Or would I have to go through another class, or do something else to get that text? Thank you so much, to anyone who answers. It's very late for me now, and this program is due in a few hours (meaning I'll be having another sleepless night). Desperate may be too strong a word, but I'm something close enough.

• DrawString with character wrapping

  - by Roy

  Hi all, I'm creating a fatal error dialog for a Windows Mobile Application using C#. The problem is when I try to draw the stacktrace using DrawString, half of my stacktrace is getting clipped off because DrawString uses word wrapping instead of character wrapping. For those who don't understand the explanation: When i draw the stacktrace, it comes out as this: at company.application.name.space.Funct at company.application.name.Function(St at etc. etc. And i want it to print like this: at company.application.name.space.Funct ion(String sometext, Int32 somenumbe r) at company.application.name.Function(St ring sometext, Int32 somenumber, Int 32 anothernumber) at etc. etc. Is this possible in Csharp?

• Why doesn't my CreateRibbonExtensibilityObject method get called?

  - by DGGenuine

  Hi I've been tinkering around with the two techniques to modify the ribbon with an MS Word addin (Visual Studio 2010, .NET 3.5), a Microsoft.Office.Tools.Ribbon.OfficeRibbon and Microsoft.Office.Core.IRibbonExtensibility. I was hoping to switch between the two in my addin's CreateRibbonExtensibilityObject, but for some reason it is not called now. The documentation says that if an addin implements CreateRibbonExtensibilityObject that it will be called. When I create a fresh project to test doing this very thing, it works. I'd prefer not to abandon my project as-is. Any ideas? Thank you.

• Bibtex with no references title

  - by Bryan Ward

  I am working on writing a scientific poster in LaTeX, and I want to include a few references for my work. Because this is a poster, I have my own customized headers for different sections, and don't want my related works to have a separate title. Essentially I have something like this: \begin{textblock}{5.5}(19.5,11) \CHead{Related Work} %a newcommand header I wrote \bibliographystyle{acm} \bibliography{mybib} \end{textblock} And it comes out with a header called "Related Work" like I want, but it also under that says "References", which I don't want. I found a few websites that said that I could override this with something like \renewcommand\refname{} But all this does is take the word "References" out, but the space allotted for the title is still there. Is there a way to completely eliminate the title and any space it may take up?

• Algorithm for matching partially filled words

  - by adnanhb

  Hello All, I am writing a game which when given a partially filled word, searches a dictionary and returns all the matching words. To that effect, I am trying to find an algorithm that can be used for the said purpose. For example, given - - a -, the algorithm will search a dictionary for all the words which have length 4 and have 'a' as the third letter. Is there such an algorithm already? If not, can somebody given a rough idea of how to design such an algorithm? Thanks in Advance.

• How to access the theming Fonts and Colors on GTK/Gnome

  - by Lothar

  Lets say i want to write a special text editor widget. How can i get the default themed colors for texts, selected text and background and which are the users default fonts? I see that GNOME does define 5 special system fonts and default sizes for this purpose in the GNOME Appearance Configuration dialog, but i haven't found a single word in the GTK documentation how to access them (and the GTK mailing list is a joke:-( ). Windows and Cocoa both give me dozens of system values. I found the GtkStyle class but this doesn't seem to be what i need.

• How to use MySql date_add in Nhibernate?

  - by jalchr

  This really puzzled for hours, I searched all over the internet, but got no working solution. Can someone point where the problem is ... thanks ! I created my own dialect class public class MySQLDialectExtended : MySQLDialect { public MySQLDialectExtended() { RegisterFunction("date_add_interval", new SQLFunctionTemplate(NHibernateUtil.Date, "date_add(?1, INTERVAL ?2 ?3)")); } } Then I try to use it as follows: query.Append( " ( date_add_interval(D.ApprovalDate, 1, YEAR) < current_timestamp() < date_add_interval(D.RenewalDate, -1, YEAR) )"); It fails with following exception: NHibernate.Hql.Ast.ANTLR.QuerySyntaxException : Exception of type 'Antlr.Runtime.NoViableAltException' was thrown. near line 1, column 677 where the column number is at the end of the first 'YEAR' word. Edit: here is my configuration <property name="dialect">MyCompanyName.MySQLDialectExtended, MyCompanyName</property> <property name="hbm2ddl.keywords">none</property>

• Screenshot of the Nexus One from adb?

  - by Marcus

  My goal is to be able to type a one word command and get a screenshot from a rooted Nexus One attached by USB. So far, I can get the framebuffer which I believe is a 32bit xRGB888 raw image by pulling it like this: adb pull /dev/graphics/fb0 fb0 From there though, I'm having a hard time getting it converted to a png. I'm trying with ffmpeg like this: ffmpeg -vframes 1 -vcodec rawvideo -f rawvideo -pix_fmt rgb8888 -s 480x800 -i fb0 -f image2 -vcodec png image.png That creates a lovely purple image that has parts that vaguely resemble the screen, but it's by no means a clean screenshot.

• Emacs: ac-slime for auto complete

  - by Boris

  I am trying to add auto complete for *.lisp files. My slime setting is: (add-to-list 'load-path "~/.emacs.d/plugins/slime/") (setq slime-lisp-implementations '((sbcl ("/opt/sbcl/bin/sbcl" "--core" "/opt/sbcl/lib/sbcl/sbcl.core") :coding-system utf-8-unix :env ("SBCL_HOME=/opt/sbcl/lib/sbcl")) (ccl ("/opt/ccl/lx86cl64") :coding-system utf-8-unix))) (require 'slime-autoloads) (slime-setup '(slime-fancy)) And ac-slime setting is: (require 'ac-slime) (add-hook 'slime-mode-hook 'set-up-slime-ac) (add-hook 'slime-repl-mode-hook 'set-up-slime-ac) (eval-after-load "auto-complete" '(add-to-list 'ac-modes 'slime-repl-mode)) Each time I type a word in *.lisp file, auto complete popups some candidates but after a second minibuffer outputs error in process filter: Reply to canceled synchronous eval request tag=slime-result-6-19579 sexp=(swank:simple-completions "de" (quote "COMMON-LISP-USER")) and the popup stuck for a while. After that I can continue my selection. My question is how to remove this error and stuck? Any help is appreciated.

• How to pre-process CSV data for FasterCSV?

  - by Katherine Chalmers

  We're having a significant number of problems creating a bulk upload function for our little app. We're using the FasterCSV gem to upload data to a MySQL database but he Faster CSV is so twitchy and precise in its requirements that it constantly breaks with malformed CSV errors and time out errors. The csv files are generally created by users' pasting text from their web sites or from Microsoft Word docs so it is not reasonable to expect that there will never be odd characters like smart quotes or accents in the data. Also users aren't going to be readily able to identify whether their data is perfect enough for FasterCSV or not. We need to find a way to fix it for them automatically. Is there a good way or a reliable tool for pre-processing CSV data to fix any nits in the data before having the FasterCSV gem process it?

• documentBuilder: The process cannot access the file because it is being used by another process

  - by st mnmn

  I am using DocumentBuilder (of openXML api), to those who doesn't know the documentBuilder I'll give a short explanation: it has a function 'BuildDocument' which gets list of sources (each source contains wmldocument), and string of fileName to save to. public static void BuildDocument(List<Source> sources, string fileName) the purpose of this function is to build one word docx which contains all the sources. it merges some docs to one. at the end of its functionality it saves the doc using: File.WriteAllBytes(...) but when I run my project on the server I keep getting the error: "The process cannot access the file because it is being used by another process." few times it works ok. and in the visualStudio it also works without errors. what can be the problem?

• php question regarding arrays

  - by Martin

  Hi there, I'm a (complete) php noob and need a little help with something. I'm working on a project whereby a user can select up to 6 categories via a form (I'm using ExpressionEngine). The output is like this: "Cat1","Cat2","Cat3" ...and so on. The user can select up to 6 categories on that form. What I need: even if my result is 3 categories I need to have 6 'cells' - for want of a better word - even if they're empty: "Cat1","Cat2","Cat3","","","" I've tried this: <?php $str = '(output goes here)'; print_r(explode(',', $str, 6)); ?> ...but the output give me: Array ( [0] => Cat1 [1] => Cat2 [2] => Cat3 [3] => [4] => [5] => ) How do I get from that to this: "Cat1","Cat2","Cat3","","","" Does this make sense? Thanks Martin

• How do I sort in solr by term frequency in multiple fields?

  - by user1488380

  I have been assigned a task that I should change our solr search to sort a list returned by solr by using the term frequency. Well, I´ve found a way to do so simply by using omitNorms="true". The problem is, that this won´t work when I am doing a field - search, say by name: q=name:jones Following this example I get a list of document whose term frequency is the highest for the "name" field. But What I wanted to achieve is to have a query that is giving my a list of documents whose term frequency is the highest for ALL fields. Example: If a User named Jones also has the word "Jones" in his biography 10 times I want that document ranked higher. Is that possible ?

• Is there any project estimation tool to give estimate for web design/ development work?

  - by jitendra

  Is there any project estimation tool which gives estimates for web design/ development work? I don't have to calculate Price just want to calculate estimated time. Just for example, for things like: Page creation (layout in XHTML) CSS creation Content creation (Word to HTML, including images in some pages) Bulk PDF upload PHP Script for Form Testing all pages I need like Items Quantity Time for each task(min) Estimated total (in hour) PDF upload x 30 = 2 min = 60 Min pages with images x 30 = 15 min for each = 60 Min Is there any simple JQuery calculator power with JQuery? Where we can add add/remove custom thing to calculate time? Or any other free online/offline tool ?

• Query not returning rows in a table that don't have corresponding values in another [associative] ta

  - by Obay

  I have Table: ARTICLES ID | CONTENT --------------- 1 | the quick 2 | brown fox 3 | jumps over 4 | the lazy Table: WRITERS ID | NAME ---------- 1 | paul 2 | mike 3 | andy Table: ARTICLES_TO_WRITERS ARTICLE_ID | WRITER_ID ----------------------- 1 | 1 2 | 2 3 | 3 To summarize, article 4 has no writer. So when I do a "search" for articles with the word "the": SELECT a.id, a.content, w.name FROM articles a, writers w, articles_to_writers atw WHERE a.id=atw.article_id AND w.id=atw.writer_id AND content LIKE '%the%' article 4 does not show up in the result: ID | CONTENT | NAME ----------------------- 1 | the quick | paul How do I make article 4 still appear in the results even though it has no writers?

• Corporate Wiki Organization - Technical Documentation

  - by Dave Jarvis

  Corporations have documents describing various aspects of their technical systems, including: Custom Applications Custom Development Frameworks Third Party Applications Accounting Bug Tracking Network Management How To Guides User Manuals Software Tools Web Browsers Development IDEs Graphics GIMP xv Text Editing File Transfer ncFTP WinSCP Hardware Servers Web Database Exchange File Network Devices Printers What other items are missing from the list, and how would you organize it? (For example, would Software Tools make more sense under Third Party Applications?) Try to think about where you, a software developer, would expect to find the information by browsing (not searching). A few constraints: The structure should not go beyond three levels deep. Avoid the word "and" in favour of two different categories. Keep the structure general: it should appy as broadly as possible. Target audience is primarily technical.

• How to center text around point using xaml

  - by Pete d'Oronzio

  I would like to be able to place the word "hello" centered on a specific point. I need to do this completely in XAML without extra code. Best I can tell, all the text alignment properties/styles in XAML act on text within some bouding canvas or other element. Since I don't know the length of the text I want to center, I can't center it using my own code. The reason I need to solve the problem entirely in XAML is that I'm not using WPF to create the XAML, I'm writing it directly to an XML DOM. It will then be loaded into a Silverlight or WPF control for display. In most graphic languages, including SVG, which is where my code originated, text can be aligned against a "stationary point" without a bounding box. Any suggestions appreciated

• 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?

• emacs & icicles: auto-completion from a dictionary?

  - by Mica

  I just installed icicles with emacs, and so far I am liking it a lot. I'm not entirely sure if this is possible, but I would like to implement (or use, if it already exists) a feature in icicles that would auto-complete words from an English dictionary. So, if I'm writing something and need a word that rhymes with floor, I can type in *or, or even better, for alliteration, type in flo* and have it return all the words from the dictionary that start with flo Questions: Does something like this exist? If it does not exist, what would be the best way to go about this? Should I somehow hook into aspell? Or just index a long file of words?

• display of umlauts in firefox

  - by Mike D

  I was doing some web searching and found some strange things involving umlauts. For example if you do a google or yahoo search for the word "nther" you are likely to find things like G&#xfc;nther which I take to be Gunther with an umlaut over the u. Now my question is what if anything can I do to cause these characters to be properly displayed by Firefox under windows XP? An amazing thing is that I had to introduce spaces in the G & # etc string otherwise it was properly displayed here as u with umlaut!

• user table with javaDB and hybernate from within grails

  - by Ralf

  let's see if I can ask this in an understandable way... I started with grails and created a domain class called user. As far as I understand, hybernate is used to map this domain class to the database. This works pretty fine with hsqldb. Now I tried to switch to javaDB and get an error message because the table is called "user" (which seems to be a reserverd word for javaDB). So a statement like create table user ... will result in an error message. create table "user" ... works, but hybernate seems not put put the table name in quotes. How can I configure hybernate to use quotes in order to make it work with my table name? PS: yes, I know, I could map the domain class to another table name... :-)

• Text editing best practices (with tags, etc.)

  - by Ron

  Hi there, I want to create a text field with some text, that is styled with tags. Think of MS Word, some ext is bold, some is a headline, etc. The tags that style the text are not visible to the user, he just sees the text in bold. How do I preserve these tags? I mean when I backspace over the closing bold-tag, for example, how do I preserve that and prevent that the rest of the text is now bold until the end? I guess this is a pretty basic question for experiences programmers. Are there any algorithms or best practices? This problem surely has been solved before, any pointers? (If this is of any concern, I develop for the iPhone OS and the text field will be a UITextView, but my question is more general I guess.) Thanks in advance!

• Skype a-like PlugIn

  This is not really a programming question but please bear with me as I just need some push to the right road. What is and what should I search for to create a Skype A-Like plugin? I want to be able to capture the Phone Number (Web Browser, Word and Outlook for starts) and change it to present a link that the user can click to search that Phone Number in the CRM Application, given him the ability to open that client profile or make a call (we have a PBX Dial software). But I have no idea what this technology is called in order to start looking for some ideas on how to accomplish this. Thank you

• Adding barcodes to pdfs

  - by calccrypto

  is there any way to do something like a mail merge, where the data (9-15 chars long) is converted to a barcode? im using trying to use openoffice's code128 for calc, but for some reason, every 10 strings, the barcode goes crazy, and the ascii tells me to register at the site where the extension came from, which i dont want to do i also found one for oodraw, but that requires the values to be inputted manually. since im not familiar with the macros, i can't write something that will do it automatically what im trying to do is: take an old pdf (only 1 page) covert it to word or picture or something add a function/macro/whatever to show a barcode (whether or not the barcode shows in this file, i dont care), given a string from excel data reconvert to separate pdfs or some other way that adds barcodes to pdfs all other free programs i have found do not do this nicely, and since im not really a pdf person, im not going to buy random programs. i just need this done for one large batch of data
