• Promoting letters in a string to the next letter in java

  - by CSD1988

  I'm having issues figuring out how to get my code to increment the string that is given by user input so that when a user chooses to replace a letter like z it would go to a, b to c ect. The catch is I have to do this without using boolean. I am supposed to get this by using arithmetics to get the promotion from z to a from the users input. Plus must be only lower case letters from a-z. Any help would be appreciated thanks.

• Regex for Date DD-MM-YYYY

  - by Josh M

  I have the following expression which will be used as date validation in the HTML5 "pattern" attribute. ?:0[1-9]|1[0-9]|2[0-9])|(?:(?!02)(?:0[1-9]|1[0-2])-(?:30))|(?:(?:0[13578]|1[02])-31))-(?:(?:0[1-9]|1[0-2])-(?:19|20)[0-9]{2} I want it to allow only valid dates, using "-" as a separator. This means up to 29th in February if it's a leap year, and 30/31 for other months respectively. Currently, it only allows years starting with 2 (2012) and months up to 12 (December). But it limits the day to 29 regardless of which month. Can anybody help me fix it?

• PHP PDO - bindValue PARAM_BOOL as string

  - by PHP_guy

  I'm freaking out here and can't figure out what's wrong. I'm pretty new to PDO, but everything works in my code except for booleans which are sent as strings. My code (simplified): $sql = 'SELECT * FROM pages WHERE clean_url_slo = :clean_url_slo AND published = :published LIMIT 1'; $clean_url_slo = 'home'; $published = true; Then I prepare stuff and execute it like this (simplified): $stmt = $db->prepare($sql); $stmt->bindValue(':clean_url_slo',$clean_url_slo,PDO::PARAM_STR); $stmt->bindValue(':published',$published,PDO::PARAM_BOOL); $stmt->execute(); And then here is what comes to mysql (from the mysql log - the query mysql received): 91 Query SELECT * FROM pages WHERE 1=1 AND clean_url_slo='domov' AND published='1' ORDER BY id desc LIMIT 1 As you can see, published is an integer - so always true, which is not OK. Why is that if I'm declaring it as a boolean? using: WAMP SERVER PHP version: 5.3.9 Mysql: 5.5.20 Many thanks for your help..

• Generating Fibonacci series in F#

  - by photo_tom

  I'm just starting to learn F# using VS2010 and below is my first attempt at generating the Fibonacci series. What I'm trying to do is to build a list of all numbers less than 400. let fabList = let l = [1;2;] let mutable a = 1 let mutable b = 2 while l.Tail < 400 do let c = a + b l.Add(c) let a = b let b = c My first problem is that on the last statement, I'm getting an error message "Incomplete structured construct at or before this point in expression" on the last line. I don't understand what I'm doing wrong here. While this seems to be an obvious way to build the list in a fairly efficient way (from a c++/C# programmer), from what little I know of f#, this doesn't seem to feel to be the right way to do the program. Am I correct in this feeling?

• Regex whitespace and special characters

  - by Sam R.

  I have this regular expression: [^\\s\"']+|\"([^\"]*)\"|'([^']*)' which works for splitting a string by white spaces, and anything within a quotation is not delimited. However, I notice that if I put in a string that starts with "" no matches are found. How would I correct this? For example, if I enter " test 2". I want it to match to [, test, 2] Note: using java to compile the regex, here is some code Pattern pattern = Pattern.compile("[^\\s\"']+|\"([^\"]*)\"|'([^']*)'"); Matcher matcher = pattern.matcher(SomeString); while (matcher.find()){ String temp = matcher.group(); //... Do something ... } Thanks.

• Allow alphanumeric, punctuation, and spaces

  - by bccarlso

  I'm pretty new to regular expressions, and MAN do they give me a headache. They are so intimidating! For an email campaign I'm doing, a user will click a link out of the email with a few URL parameters filled in for them, to make filling out a form easier. I want to prevent any injection hacks or whatever it's called, but need to allow the $_GET parameters to be alphanumeric, have punctuation, and have spaces. If someone has a good method for this, I'd appreciate it, but right now I have: foreach($_GET as $m=>$n) { $get[$m] = preg_replace('(^[a-z0-9 \-\_\.]+)i',' ',$n); } I would like to be able to replace all characters NOT found with this regular expression, which I believe I use ?!, but I can't get that to work either. Any help in getting this to work would be appreciated!

• Is possible to set generic type by another class?

  - by Soul_Master

  I use ASP.NET MVC for serving web application and I want to create something like the following code. <% using(HTML.Form(Model)) { %> <% HTML.CreateTextBox('txt1', x => x.Property1); <% } From the above code, Form extension method will receive object that represent type of current Model object in current View page. Next, CreateTextBox method will receive type from Form method and I can bind textbox to some property of this model. Update 1 The following code is code of CreateTextBox method that will create instance of TextBox class. public static CreateTextBox(string value, Expression<Func<object>> bindedProperty) { // T should be receive from HTML.Form method or class return new TextBox<T>(value); } Is it possible to creating some code that doing something like the above code?

• Get name and value from the input tag

  - by DroidIn.net

  Before you say "oh no, not again" here I'm stating my case. I'm parsing part of HTML output and the only thing I'm interested in is name and value attributes of each <input/ tag. HTML is actually HTML fragment, may not be well-formed. I don't have DOM or HTML parser and I don't try to parse nested elements anyway. The problem is that I don't know the order or number of attributes so it could be <input name="foo" value="boo"/> or <input type="hidden" name=foo> or <input id=blah value='boo' src="image.png" name="foo" type="img"/>. Is there a single regular expression that would get me values of name and value attribute in predictable order? I wouldn't have asked the question if I could assume that name attribute always precedes value but unfortunately this is not the case

• Validation controls error message from Resource file and parameterized

  - by BigBoss

  Hi, I would like to get validation messages for validation controls from resource files. I know I can do that easily by following code snippet. <%$ Resources:[filename prefix,]resource-key %> or <asp:Label ID="Label1" runat="server" meta:resourcekey="resource-key-prefix" /> But I would also like to parameterized it. e.g. Above Resource Expression will give me message like "Fill Information.". What I have in resource file is "Fill {0} Information." which should show end user message like "Fill Address Information.".

• Scheduling a visual studio load test using powershell giving me BSOD

  - by user952342

  I have a visual studio load test which I want to run every hour so that I can start to collect some data. To do this, I thought it would be best to make a little powershell script and put a command like this inside: Invoke-Expression -command "& '$env:VS100COMNTOOLS..\IDE\mstest.exe' /testcontainer:"C:\Users\benb\Documents\Visual Studio 2010\Projects\BBPerformanceTest\bin\Debug\HomePageOnly.loadtest"" That command works fine, but sometimes when its run I get a blue screen of death. However, when I run my load test through the visual studio GUI, I never get a BSOD. two questions: is it possible to avoid this BSOD? Is there another way I can schedule my load test? Thanks

• Multiple LIKE, OR MySql Queries Match

  - by Codex73

  Search for: 'chemist' Problem: query which will match a string like 'onechemist' but not 'chemist'. SELECT id,name FROM `records` WHERE name LIKE '%". mysql_real_escape_string($q) ."%' This alternate try won't work: SELECT id,name FROM `records` WHERE name LIKE '%". mysql_real_escape_string($q) ."%' OR name LIKE '". mysql_real_escape_string($q) ."%' OR name LIKE '%". mysql_real_escape_string($q) ."' How could I compile the above into one single query that will match any field which has the string or optimize the query into a better expression?

• JAVA: How do I accept input during a certain period of time only

  - by sebrock

  Im trying to do a simple game where I continually need input from players. This needs to happen during a certain time period only. Everything that is sent after that will be discarded. After the time period a new game starts. So: Start game Wait for input from all players during 10 seconds 10 secs no more input Calculate the winner and do some stuff Goto 1. I was thinking using a timer and timertask to keep track of time and maybe use a boolean variable that changes from "open" to "closed" after 10 seconds? Please give me some advise on this.

• it is possible to "group by" without losing the original rows?

  - by toPeerOrNotToPeer

  i have a query like this: ID | name | commentsCount 1 | mysql for dummies | 33 2 | mysql beginners guide | 22 SELECT ..., commentsCount // will return 33 for first row, 22 for second one FROM mycontents WHERE name LIKE "%mysql%" also i want to know the total of comments, of all rows: SELECT ..., SUM(commentsCount) AS commentsCountAggregate // should return 55 FROM mycontents WHERE name LIKE "%mysql%" but this one obviously returns a single row with the total. now i want to merge these two queries in one single only, because my actual query is very heavy to execute (it uses boolean full text search, substring offset search, and sadly lot more), then i don't want to execute it twice is there a way to get the total of comments without making the SELECT twice? !! custom functions are welcome !! also variable usage is welcome, i never used them...

• Jquery Match() IP Address?

  - by user1635970

  I'm using a jquery script to validate form fields. This works well, but I'd like to change the validation of one field to check for IP Addresses. The regex I want to use is : \b(25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)\.(25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)\.(25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)\.(25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)\b How do I amend the below to work with this ? (This is how the validation works for email address) jQuery("#Email").validate({ expression: "if (VAL.match(/^[^\\W][a-zA-Z0-9\\_\\-\\.]+([a-zA-Z0-9\\_\\-\\.]+)*\\@[a-zA-Z0-9_]+(\\.[a-zA-Z0-9_]+)*\\.[a-zA-Z]{2,4}$/)) return true; else return false;", message: "Should be a valid Email id" });

• Emacs auto-minor-mode based on extension

  - by vermiculus

  I found this question somewhat on the topic, but is there a way [in emacs] to set a minor mode (or a list thereof) based on extension? For example, it's pretty easy to find out that major modes can be manipulated like so (setq auto-mode-alist (cons '("\\.notes$" . text-mode) auto-mode-alist)) and what I'd ideally like to be able to do is (setq auto-minor-mode-alist (cons '("\\.notes$" . auto-fill-mode) auto-minor-mode-alist)) The accept answer of the linked question mentions hooks, specifically temp-buffer-setup-hook. To use this, you have to add a function to the hook like so (add-hook 'temp-buffer-setup-hook 'my-func-to-set-minor-mode) My question is two-fold: Is there an easier way to do this, similar to major modes? If not, how would one write the function for the hook? It needs to check the file path against a regular expression. If it matches, activate the desired mode (e.g. auto-fill-mode).

• mod_rewrite rule for all urls except ones with some words

  - by zlog

  How do I write a mod_rewrite regulare expression rule that is the opposite of this: ^(.+)/path/(page1|page2)+$ ie, I want all pages except blah/path/page1 and blah/path/page2 to redirect to another path, where the x in blah/path/x is used in the new path. For example, I'd like write a rewrite rule like: RewriteRule some_regex /index.php?path/show/$1 [L] where some_regex would pull out the last component of a url in the format: /something/path/some_param to redirect to /index.php/path/show/some_param I'm trying to use ! and [^] syntax, but I don't quite understand how these work, especially when they involve words not single characters.

• How do I write a regex that ignores strings starting with a particular prefix, and captures everythi

  - by Mark Rogers

  Background: I'm trying to come up with a regex for a rewrite rule that will take anything that does not start with a particular prefix, and add that prefix to it. But urls that already have the prefix should be rejected by the regular expression (because they already have the url). Example: If the prefix is s1 a string like home will capture the home part. But a string like s1/home, will not capture anything. This way I can add the capture group onto the prefix, so that 'home' will become 's1/home'. I've tried (^s1/), but I'm missing something here, because that rejected 'home' for some reason.

• How can I use "IF statements" in a postgres trigger

  - by Dan B

  I have a trigger function that I only want to fire on certain instances of INSERTS, in this case, if do_backup = true. If it fires in all instances, I get an infinite loop. The logic seems pretty simple to me, and the rest of the function works. But the trigger function does not seem to register my conditional and always runs, even when backup = true. CREATE OR REPLACE FUNCTION table_styles_backup() RETURNS TRIGGER AS $table_styles_backup$ DECLARE ... do_backup boolean; BEGIN SELECT backup INTO do_backup FROM table_details WHERE id=NEW.table_meta_id; IF (do_backup = true) THEN ... INSERT INTO table_styles_versions ( ... ) VALUES ( ... ); END IF; RETURN NULL; END; $table_styles_backup$ LANGUAGE plpgsql; CREATE TRIGGER table_styles_backup AFTER INSERT ON table_styles FOR EACH ROW EXECUTE PROCEDURE table_styles_backup();

• DB fields not showing up in association custom queries?

  - by Kevin

  I have a notification list that the user can select different show options for different kinds of notifications along with how many results are returned. I'm keeping them in the user model because I want the custom sort to stay with the user between sessions. Here is the association in my user model: has_many :notifications, :class_name => "Notification", :foreign_key => "user_id", :conditions => ["won = ? and lost = ? and paid = ?", self.prefs_won, self.prefs_lost, self.prefs_paid], :limit => self.prefs_results.to_s But when I use the above code, Rails throws me an "unknown method" error for self.prefs_won. It is definitely a field in my database and set as a boolean value, but Rails can't find it... what's the problem?

• @ExceptionHandler doesn't handle the thrown exceptions

  - by Javi

  Hello, I have a method in my controller which will handle the exceptions thrown by the application. So I have a method like this one. @Controller public class ExceptionController { @RequestMapping(value="/error") @ExceptionHandler(value={Exception.class, NullPointerException.class}) public String showError(Exception e, Model model){ return "tiles:error"; } } And to try I if it works I throw a NullPointerException in another method in other method controller: boolean a = true; if(a){ throw new NullPointerException(); } After the exception is thrown it is printed in the JSP, but it doesn't go throw my showError() method (I've set a breakpoint there and it never enters). showError() method will catch the exception and will show different error pages depending on the exception type (though now it always shows the same error page). If I go to the url /error it shows the error page so the showError() method is OK. I'm using Spring 3. What can be the problem? Thanks.

• Which is the 'correct' way to do this (if statement)

  - by frinkz

  I've got plenty of these lying around, and I'm wondering if I'm going to face any trouble - or performance problems. I have method A: MyClass monkey; ... if(monkey != null) { ... } Or method B: boolean hasMonkey; //This is set to TRUE when monkey is not null MyClass monkey; ... if(hasMonkey) { ... } On a functional level, they both do the same thing. Right now, I'm using method A. Is that a bad way of doing things? Which is going to perform better?
