• How to ignore the .classpath for Eclipse projects using Mercurial?

  - by Feanor

  I'm trying to share a repository between my Mac (laptop) and PC (desktop). There are some external dependencies for the project that are stored on different places on each machine, and noted in the .classpath file in the Eclipse project. When the project changes are shared, the dependencies break. I'm trying to figure out how to keep this from happening. I've tried using .hgignore with the following settings, among others, without success: syntax: glob *.classpath Based on this question, it appears that the .hgignore file will not allow Mercurial to ignore files that are also committed to the repository. Is there another way around this? Other ways to configure the project to make it work?

• HASHREF in Perl

  - by Uri

  I'm trying to decrypt a Perl code which I'm not familiar with, somehow related to HashRef. I'm using Amazon::S3, but my question is a general Perl question. See the code below: use Amazon::S3; my $s3 = Amazon::S3-new( ... ); my $response = $s3-buckets; Documentation (here) sais, about s3-buckets: Returns undef on error, else HASHREF of results The following line is working for me, but I don't understand why: for $b in ( @ { $response-{buckets} } ) { print "bucket: " . $b-bucket . "\n"; } I'm buzzled by each operator on the first line. What type exactly are $response, $respone-{bucket}. Looks like the expression within the 'for' is an array, but I don't understand this syntax: @{ ... }?

• ASP.NET 4.0 Route expression builder inside Listview control

  - by Carlos Lone

  One of the features of ASP.NET 4.0 is Route Expression builder which allows you to set up hyperlinks like this: <asp:HyperLink runat="server" NavigateUrl="<%$ RouteUrl:RouteName=productos,categoria=Cereales,id=2 %>" >Productos</asp:HyperLink> Now I'm wondering if I can use this sort of syntax inside a ListView Control, I know is possible, but the tricky thing is that I want to genereate de route key value dynamically. So instead to write id=2 I would like to write id=<%# Eval("CategoryID") % . Can I do that?, if so, how should I write it. Thanks for your help!

• Setting button width with fx:Style

  - by Kamo

  I have 4 buttons, all of them have the same width. <s:Button id="btn1" width="{btnWidth}" /> <s:Button id="btn2" width="{btnWidth}" /> <s:Button id="btn3" width="{btnWidth}" /> <s:Button id="btn4" width="{btnWidth}" /> Is it possible to set their width with Style, something like this: s|Button{ width: btnWidth; } I tried it, but auto-complete isn't working, which leads me to think that there's something wrong with the syntax. Basically my goal is to not have the width property set specifically for all 4.

• Applying a function with multiple inputs using Map? (Haskell)

  - by Schroedinger

  G'day guys, Trying currently to finish up a bit of homework I'm working on, and having an issue where I'm trying to apply map across a function that accepts multiple inputs. so in the case I'm using processList f (x:xs) = map accelerateList f xs x xs processList is given a floating value (f) and a List that it sorts into another List Accelerate List takes a floating value (f) a List and a List Object through which it returns another List Object I know my Accelerate List code is correct, but I cannot for the life of me get the syntax for this code working: processList :: Float -> [Object] -> [Object] accelerate f [] = [] accelerate f [x] = [(accelerateForce f x x)] accelerate f (x:xs) = map accelerateList f xs x xs Any ideas? I've been scratching my head for about 3 hours now. I know it's something really simple.

• Copying a mysql database from localhost to remote server using mysqldump.exe

  - by Ankur

  I want to copy a mysql database from my local computer to a remote server. I am trying to use the mysql dump command. All the examples on the internet suggest doing something like The initial mysql> is just the prompt I get after logging in. mysql> mysqldump -u user -p pass myDBName | NewDBName.out; But when I do this I get You have an error in your SQL syntax; check the manual that corresponds ... to use near 'mysqldump -u user -p pass myDBName | NewDBName.out' Since I have already logged in do I need to use -u and -p? Not doing so gives me the same error. Can you see what is wrong?

• String Functions in IIS Url Rewritting Module

  - by Nariman

  The IIS URL Rewrite Module ships with 3 built-in functions: * ToLower - returns the input string converted to lower case. * UrlEncode - returns the input string converted to URL-encoded format. This function can be used if the substitution URL in rewrite rule contains special characters (for example non-ASCII or URI-unsafe characters). * UrlDecode - decodes the URL-encoded input string. This function can be used to decode a condition input before matching it against a pattern. The functions can be invoked by using the following syntax: {function_name:any_string} The question is: can this list be extended by introducing a Replace function that's available for changing values within a rewrite rule action or condition?

• boolean type for while loop in bash?

  - by user151841

  I have a cron script on a shared web host that occasionally gets killed. I'd like to make a loop in bash that tries again if it gets killed, because most of the time it will make it. I'm having trouble with the syntax for storing a boolean value :P #!/bin/bash VAR=0; while [ $VAR ]; do if nice -19 mysqldump -uuser -ppassword -h database.hostname.com --skip-opt --all --complete-insert --add-drop-table database_name > ~/file/system/path/filename.sql; then VAR=1; fi done So the script recovers from a killed process okay, but once it's run properly, the new VAR value doesn't kill the while loop. What am I doing wrong?

• Cocoa Screensaver Framework error message

  - by Veljko Skarich

  Hi, I'm trying to make a screen saver using the cocoa screensaver framework. The project builds fine and generates the .saver file, but when I try to run it in the preferences test window, it displays the error message: "You cannot use the screen saver with this version of Mac OSX. Please contact the vendor to get a newer version of the screen saver" I have the xcode settings to Release | x86_64, and I am running OSX 10.6.6 on a 2.4 GHz Intel Core i5 Macbook Pro. I've searched around online, and most of the solutions to this error message seem addressed to making sure the build is 64-bit, which the x86_64 setting should indeed take care of. I am trying to play a QT movie in the screensaver, if that makes any difference. I am at a loss, any help would be appreciated. Thank you.

• Javascript appending onload to a popup window

  - by Hypnotic Meat

  I'm trying to append an onload event to a popup window in the following manner: var explorerWindow = window.open(PARAMS...); explorerWindow.onload = function() {window.opener.unlockObj(id);} The idea is to make the button that generates the popup window readonly, making it usable again once the popup window has loaded all of its contents. However, the event doesn't seem to be firing at all. I even changed it to the following and got nothing: explorerWindow.onload = function() {alert("bloop");} Is there something terribly wrong with my syntax or am I missing something else entirely? Also, I'm using JQuery if there are any appropriate gems there that will help in this situation. I tried the following with similar results, but I'm not so sure I got the call right: $(explorerWindow).load(function() {alert("bloop");}); Any help is greatly appreciated.

• Anonymous functions in C#

  - by Maxim Gershkovich

  The following syntax is valid VB.NET code Dim myCollection As New List(Of Stock) myCollection.Add(New Stock(Guid.NewGuid, "Item1")) myCollection.Add(New Stock(Guid.NewGuid, "Item2")) Dim res As List(Of Stock) = myCollection.FindAll(Function(stock As Stock) As Boolean If stock.Description = "Item2" Then Return True End If Return False End Function) How can I accomplish the same thing in C#? I have tried... myCollection.FindAll(bool delegate(Stock stock) { if (blah blah) { } }); But it appears I have somehow structured it incorrectly as I get the following error. "Error 1 Invalid expression term 'bool'"

• OpenGL - lighting of vertices outside clip range

  - by hmp

  I have a problem with lighting in my OpenGL application. When one of the vertices of a drawn polygon goes outside the front clip plane (or has z<0, I'm not sure which), the polygon stops being lighted properly. This however happens on only one machine I tested, with Intel GMA950 card. On nVidia and ATI cards everything looks fine. I guess I am breaking some OpenGL rule here? How should I deal with it? I'd try dividing the scene into smaller polygons, but I'm not sure if it guarantees the case is eliminated (all polygons stepping outside the clipping range are offscreen).

• Declaring a prototype of type "struct" - C

  - by Jamie Keeling

  I've been racking my brains on this for a while, I'm simply trying to create a method that returns a struct as I wish to return two int's. My prototype for the method is as follows: typedef struct RollDice(); Also the method itself: typedef struct RollDice() { diceData diceRoll; diceRoll.dice1 = 0; diceRoll.dice2 = 0; return diceRoll; } The compiler shows the error: "Syntax error: ')'" for both the prototype and actual method. The struct itself: typedef struct { int dice1; int dice2; }diceData; Is it obvious where I'm going wrong? I've tried everything I can think of. Thanks

• Delphi JavaDoc Parser

  - by Christian Sciberras

  I need to parse JavaDoc (documentation) comment syntax with Delphi 7. It is well known in the java world as "JavaDoc", but I'm actually doing this for PHP, ie, parsing JavaDoc in some PHP code. Call it PHPDoc if you want to. To see how these comments work, you can see RAD IDEs like NetBeans etc. Example of JavaDoc for addition function: /** * Adds to numbers together. * @param integer $a The first number. * @param integer $b The second number. * @return integer The resulting number. */ function add($a,$b){ return $a+$b; } Please note that the parser need not be full, ie, parsing all of the PHP code. I mean, it's perfectly fine if it accepted the comment text only as input. Cheers, Chris.

• Method with throws Exception: Where is it actually handled?

  - by Esq

  Here is an example code, I am throwing an exception here, it works perfectly fine without the try/catch block of code for some reason. Do I have to handle this inside this method "EntryDelete" or Do I have to handle this where the method is called from? If so can I see an example, what do I have to import in there? What is the acceptable syntax or method to do this? public boolean EntryDelete(int entryId) throws SQLException{ this.open(); kDatabase.delete(kENTRY_TABLE, kENTRY_ENTRY_ID + "=" + entryId, null); this.close(); return true; } Thanks

• Regular expressions in python unicode

  - by Remy

  I need to remove all the html tags from a given webpage data. I tried this using regular expressions: import urllib2 import re page = urllib2.urlopen("http://www.frugalrules.com") from bs4 import BeautifulSoup, NavigableString, Comment soup = BeautifulSoup(page) link = soup.find('link', type='application/rss+xml') print link['href'] rss = urllib2.urlopen(link['href']).read() souprss = BeautifulSoup(rss) description_tag = souprss.find_all('description') content_tag = souprss.find_all('content:encoded') print re.sub('<[^>]*>', '', content_tag) But the syntax of the re.sub is: re.sub(pattern, repl, string, count=0) So, I modified the code as (instead of the print statement above): for row in content_tag: print re.sub(ur"<[^>]*>",'',row,re.UNICODE But it gives the following error: Traceback (most recent call last): File "C:\beautifulsoup4-4.3.2\collocation.py", line 20, in <module> print re.sub(ur"<[^>]*>",'',row,re.UNICODE) File "C:\Python27\lib\re.py", line 151, in sub return _compile(pattern, flags).sub(repl, string, count) TypeError: expected string or buffer What am I doing wrong?

  I'm trying to insert a php excerpt with SQL (I understand this is outdated, but am trying to grasp the syntax first) into my HTML page, and I've got the following table: ID Name Element1 Element2 0 John John's 1st John's 2nd 1 Bill Bill's 1st Bill's 2nd 2 Steve Steven's 1st Steve's 2nd I'm trying to get the for loop that will essentially print out the following in my html page Name: Name where ID=0 Element1: Element1 where ID=0 Element2: Element2 where ID=0 Name: Name where ID=1 Element1: Element1 where ID=1 Element2: Element2 where ID=1 and so forth. Basically, I am trying to make this process automated so that whenever a new record is added into the table, the HTML page will automatically update with a new "profile". Thank you for your help!

• SQL query: how to translate IN() into a JOIN?

  - by tangens

  I have a lot of SQL queries like this: SELECT o.Id, o.attrib1, o.attrib2 FROM table1 o WHERE o.Id IN ( SELECT DISTINCT Id FROM table1, table2, table3 WHERE ... ) These queries have to run on different database engines (MySql, Oracle, DB2, MS-Sql, Hypersonic), so I can only use common SQL syntax. Here I read, that with MySql the IN statement isn't optimized and it's really slow, so I want to switch this into a JOIN. I tried: SELECT o.Id, o.attrib1, o.attrib2 FROM table1 o, table2, table3 WHERE ... But this does not take into account the DISTINCT keyword. Question: How do I get rid of the duplicate rows using the JOIN approach?

• Need help with a LINQ ArgumentOutOfRangeException in C#

  - by Christopher Klein

  Hi there, Hoping this is a nice softball of a question for a friday but I have the following line of code: //System.ArgumentOutOfRangeException generated if there is no matching data currentAnswers = new CurrentAnswersCollection().Where("PARTICIPANT_ID", 10000).Load()[0]; CurrentAnswersCollection is a strongly-typed collection populated by a view going back to my database. The problem of course is that if there is not a corresponding PARTICIPANT_ID = 10000 I get the error message. Is there a better way to write this so that I wouldn't get the error message at all? I just dont know enough about LINQ syntax to know if I can test for the existance first? thanks.
