• Are Inherited Forms And/Or Inherited Controls possible in Managed C++

  - by Ali Akdurak

  Hello everyone The question is actually pretty self explanatory but I will further clarify it. I am building a simple application to show a load [file] for 5 different types of [files]. So all these 5 forms will have similar GUI elements such as a listbox and a load button with a small textbox/label to show the summary of the [file]'s information. My desired effect is something like visual studio's C# template for Inherited User controls or Inherited forms. I already heavily googled the concept to look for a C++ visual studio template to the trick but I couldn't find it. The word [file] is in brackets because open file dialogue will not the trick as this list of files to select form comes form an SQL server. Thanks a lot!

• 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.

• 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.

• user table with javaDB and Hibernate 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, Hibernate 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 reserved word for javaDB). So a statement like create table user ... will result in an error message. create table "user" ... works, but Hibernate seems not put put the table name in quotes. How can I configure Hibernate 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... :-)

• 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>

• 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?

• 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

• scrabble algorithm....

  - by teddy

  I'm making algorithm like crossword, but I dont know how to design the algorithm. For example: there are words like 'car', 'apple' in the dictionary. the word 'app' is given on the board. there are letters like 'l' 'e' 'c' 'r'....for making words. So the algorithm's task is to make correct words which are stored in dictionary. app - lapp - leapp - lecapp - .... - lappe - eappc - ... - appl - apple (correct answer) What is the best solution for this algorithm?

• 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?

  - 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.

• IntelliJ IDEA non standard caret behaviour

  - by Vaat666

  I have an issue with IntelliJ IDEA when selecting a big amount of text, and I cannot find the parameter to set to change that. Here is an example of the situation: My caret is on line 3 I scroll with the mouse wheel towards line 300 I press ctrl + shift I press the left button of the mouse Such an action would result in the text from line 3 to 300 being selected in all common editors (even in MS-Word I think), but not in IntelliJ. Do you know how to set this right? Thanks!

• Is there a way to make vim display "virtual characters" before/after regular patterns in the buffer?

  - by Laurence Gonsalves

  Vim has list and listchars options that make vim display "virtual characters" (by which I mean characters that aren't actually in the buffer) in certain situations. For example, you can make trailing spaces look like something else, or add a visible character to represent the newline character. I'd like to be able to enable the display of certain characters either before or after certain regular patterns ((perhaps syntax items). Sort of like syntax highlighting, but instead of just changing the color/styling of characters that are in the buffer, I'd like to display extra characters that aren't in the buffer. For example, I'd like to display a virtual : (colon) after all occurrences of the word "where" that appear at the end of a line. Is this possible, and if so, what is the necessary vimscript to do it?

• How can I extract the nth occurrence of a match in a Perl regex?

• 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 do I dynamically instantiate a class in javascript?

  - by Adam

  I'm starting out with classes in Javascript and have hit a wall. I've looked all over for a tutorial that goes a little further than simply how to construct a class (usually Animal) then extend the class and have a Method do something (Dog alert('Bark');). I have created a class that I want a user to be able to instantiate (is that the right word)? For example the first stage in my program is for the user to give the class a name, and then start to populate the various variables in the class. When they've done that they may do it again many times. So if: var className = new MyObject(); How do I dynamically create the name of the new object className and then refer to it later in the code?

• 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?

• php POST and non-english language chars passes empty

  - by haim evgi

  I'm trying to program a Hebrew site with a search option. (old site and the charset of this site is windows-1255) I am using php 5.2 with Apache 2.2, on a Debian 5 (Lenny) with appropriate code pages enabled. I am using _POST to pass arguments to a script. If I pass English word to the script everything works, but when I use Hebrew nothing is passed through the POST function. When I use ECHO to show _POST, the variable is empty. What might be the problem? P.S. this is old site that worked fine on PHP 4 with debian 4, and the problem arised only after we upgrade to PHP5+debian5.

• How to write a virtual conditional breakpoint in java

  - by Phuong Nguyen de ManCity fan

  I'm sorry if the question title may mis-inform you, but I cannot find a proper word to explain that. If you ever working with .NET, you would know that there is Assert class that will automatically wake up and attach debugger if necessary and then have debugger (Visual Studio) pausing at the Assert command, given the Assert command failed. Given I'm running a java program and having debugger connected, then how can I have debugger to break on certain condition without manually setup a break point? I'm expecting something like that: void doSomeThing(String x){ if (x==null) breakDebuggerNow(); }

• 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!

• 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

• 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!

If same item is repeated in more than one place with subitems all the subitems should be merged under a single item and also subitems should be sorted

• Perl TDS character sets

  - by skiphoppy

  I'm using the FreeTDS driver with DBD::Sybase, connecting to an MS SQL Server. When I query certain values of certain records, I get this error: DBD::Sybase::st fetchrow_arrayref failed: OpenClient message: LAYER = (0) ORIGIN = (0) SEVERITY = (9) NUMBER = (99) Server , database Message String: WARNING! Some character(s) could not be converted into client's character set. Unconverted bytes were changed to question marks ('?'). This seems to happen for records that contain special Windows character-set characters, such as curly quotes, copied and pasted from people's Outlook and Word messages. Unfortunately, I do not have any control of this database; sanitizing the input on the way in is obviously the way to go, but is not available to me. What FreeTDS settings do I need to change to be able to successfully query these records?
