• Replacing whitespace with sed in a CSV (to use w/ postgres copy command)

  - by Wells

  I iterate through a collection of CSV files in bash, running: iconv --from-code=ISO-8859-1 --to-code=UTF-8 ${FILE} | \ sed -e 's/\"//g' | \ sed -e 's/, /,/g' \ > ${FILE}.utf8 Running iconv to fix UTF-8 characters, then the first sed call removes the double quote characters, and the final sed call is supposed to remove leading and trailing whitespace around the commas. HOWEVER, I still have a line like this in the saved file: FALSE,,,, 2.40,, The COPY command in postgres is kind of dumb, so it thinks " 2.40" is not valid syntax for a numeric value. Where am I going wrong w/ my processing of the CSV file? Thanks!

• FileNotFoundException when using FileInputStream

  - by user1672817

  I am trying to access a file I have contained in the jar. The beginning of my code is as follows: import java.io.*; import java.net.*; public class intro { public static void main(String[] args) throws IOException{ URL jarUrl = intro.class.getResource("myFile.jar"); File myJar = new File(jarUrl.toString()); FileInputStream fis = new FileInputStream(myjar); } I'm getting the following error: Exception in thread "main" java.io.FileNotFoundException: file:\...myFile.jar (The filename, directory name, or volume label syntax is incorrect) at java.io.FileInputStream.open(Native Method) at java.io.FileInputStream.<init>(Unknown Source) at intro.main(intro.java:10) It seems to have no problem finding the URL or initializing the file, but I can't get the FileInputStream to work. Does anybody know what I'm doing wrong? Help would be appreciated.

• Global Exception Handlers in Java

  - by Samuh

  I am thinking of setting up a global, default Exception handler for my (Android) Mobile application(which uses Java syntax) using Thread.setDefaultUncaughtExceptionHandler(...) call. I am thinking of just displaying an Alert Dialog with appropriate message to the user. Are there any gotchas, caveats and rules that one needs to follow when setting DefaultExceptionHandlers? Any best practices like making sure that the process is killed, full stack trace is written to logs etc. ? Links to documentation, tutorials etc. that can throw some light on this are welcome. Thanks.

• Evaluate a string-expression in XSL

  - by Jerzakie

  Is there any way to evaluate a string expression in XSL? example: <myItem id="1"> <validator expression="$someVariable = '3'" /> </myItem> ... <xsl:variable name="someVariable" select="3" /> <xsl:if test="@expression"> ... I realize this syntax does not work the way I want it to, but is there any way to store the test expression in a variable and then evaluate the expression?

• Can Spring understand @Inject replacing Weld as a JSR-299 implementation?

  - by Thorbjørn Ravn Andersen

  I have noticed from several web pages that apparently Spring 3.0 supports @Inject from JSR-330. As we would really like to use JSR-299 syntax for dependency injection in our libraries for both web apps and stand-alone applications, and have alternatives to Weld, it would be nice if Spring could do this. Being a novice to Spring, I tried downloading the Spring Framework distribution and put all jars on the Eclipse build path. No Inject annotation so my existing test project using Weld did not compile. Can this be done with Spring? What do I need to do to get it running? (I am aware that Guice eventually will support this too. It is only in SVN for now, and if there is an official Spring release which can, that would be better.)

• Pointer to another classs as a property

  - by arjacsoh

  Why I receive an error when I try to create a property to another class through a pointer like that: #ifndef SQUARE_H #define SQUARE_H #include <string> //using namespace std; #include "Player.h" class Square { public: Square(int); void process(); protected: int ID; Player* PlayerOn; <--- }; #endif and the Player class is : #ifndef PLAYER_H #define PLAYER_H #include <string> //using namespace std; #include "Square.h" class Player { public: Player(int,int); // ~Player(void); int playDice(); private: int ID; int money; }; #endif I receive: syntax error missing ; before * (on the declaration of Player* PlayerOn;) and missing type specifier (on the same line...)

• jQuery way to handle select lists, radio buttons and checkboxes

  - by Álvaro G. Vicario

  When I handle HTML form elements with jQuery, I always end up with an ugly mix of jQuery syntax and plain JavaScript like, e.g.: function doStuff($combo){ if( $combo.get(0).options[$combo.get(0).selectedIndex].value=="" ){ var txt = ""; }else{ var txt = $combo.get(0).options[$combo.get(0).selectedIndex].text; } var $description = $combo.closest("div.item").find("input[name$=\[description\]]"); $description.val(txt); } Are there standard jQuery methods to handle typical operations on elements like <select>, <input type="radio"> and <input type="checkbox">? With typical, I mean stuff like reading the value of the selected radio button in a group or replacing elements in a selection list. I haven't found them in the documentation but I admit that method overloading can make doc browser kind of tricky.

• Why can't I pass in a uniqueidentifier/GUID to a stored procedure

  - by chobo2

  Hi I have this SP USE [TestDB] GO /****** Object: StoredProcedure [dbo].[sp_test] Script Date: 06/12/2010 11:47:27 ******/ SET ANSI_NULLS ON GO SET QUOTED_IDENTIFIER ON GO CREATE PROCEDURE [dbo].[sp_test] @id uniqueidentifier AS BEGIN select * from TestTbl where ProductId= @id END I then went to the SP with ms sql 2005 and clicked execute. It comes up with a box where I entered in the GUID. I copied and pasted it straight from my test database. I get this error. Msg 102, Level 15, State 1, Line 5 Incorrect syntax near 'cac671b'. So why can't I sent in GUIDs? even ones that are copied right from the database and must be valid as they where allowed into the db.

• MSBuild conditionals depending on task parameters

  - by jalf

  In MSBuild it's straightforward to define, say, a PropertyGroup which depends on the value of a property Foo: <PropertyGroup Conditional="'$(Foo)'=='Bar'" /> Is it also possible for the conditional to depend on a task parameter? For example, I'd like to use the value of the Link task's SubSystemparameter roughly like this: <PropertyGroup Conditional="'$(Link/SubSystem)'=='Console'" /> but don't know if it is possible, and if it is, what the correct syntax is. I'm pretty new to MSBuild though, so it's perfectly possible that I've missed something.

• How to get an ordered list parsed by XML parser?

  - by Matthias Doringer

  I am using a xsd schema file; there I specified an ordered list. When parsing an XML node of the kind... <myOrderedList> "element_1" "element_2" "element_3" </myOrderedList> (which is valid XML syntax) ...all XML parsers I know parse this as a single node element. Is there a way to get the XML parser parse this list for me (return it as a list or an array or whatever) or do I always have to parse it myself?

• Javascript How do I force a string + variable to be evaluated as a variable

  - by Craig Rinde

  Im not even sure how to word this and is probably why I am having trouble finding an answer in google. When the code is run currentCardRow will equal 1 therefore it should be cardSelected1 which is what is shown in the console.log. I need it to go a step further because cardSelected1 is a variable and I need it to evaluate show in the console log as Invitation. Invitation is an example of a variable for cardSelected1. I am not sure on what the correct syntax is to make this happen. var currentCardSelected = "cardSelected" + currentCardRow; Thanks for your help!

• IF/ELSE makes stored procedure not return a result set

  - by Brendan Long

  I have a stored procedure that needs to return something from one of two databases: IF @x = 1 SELECT @y FROM Table_A ELSE IF @x = 2 SELECT @y FROM Table_B Either SELECT alone will return what I want, but adding the IF/ELSE makes it stop returning anything. I tried: IF @x = 1 RETURN SELECT @y FROM Table_A ELSE IF @x = 2 RETURN SELECT @y FROM Table_B But that causes a syntax error. The two options I see are both horrible: Do a UNION and make sure that only one side has any results: SELECT @y FROM Table_A WHERE @x = 1 UNION SELECT @y FROM Table_B WHERE @x = 2 Create a temporary table to store one row in, and create and delete it every time I run this procedure (lots). Neither solution is elegant, and I assume they would both be horrible for performance (unless MS SQL is smart enough not to search the tables when the WHERE class is always false). Is there anything else I can do? Is option 1 not as bad as I think?

• powerpoint macro timer

  - by mustafabattal

  Hi, I have to complete a timer on powerpoint, it countsdown for a specificed amount of time when a shape on particular slide is clicked. I heard macros could be a way to do this, but I have very little knowledge about them. With my research I was able to add a macro and pop out a message box when a shape is clicked*. How can I implement a timer with this? VB syntax is pretty unfamiliar to me. What happens after timer finishes is another question though. *with macro in module: sub hello_world() MsgBox( 'hello world!') end sub

• Optional URL fragment in Codeigniter?

  - by DA

  This is maybe a simple syntax question or possibly a best-practices question in terms of codeigniter. I should start by saying I'm not a PHP or Codeigniter person so trying to get up to speed on helping on a project. I've found the CI documentation fairly good. The one question I can't find an answer to is how to make part of a URL optional. An example the CI documentation uses is this: example.com/index.php/products/shoes/sandals/123 and then the function used to parse the URI: function shoes($sandals, $id) For my example, I'd like to be able to modify the URL as such: example.com/index.php/products/shoes/all So, if no ID is passed, it's just ignored. Can that be done? Should that be done? A second question unrelated to my problem but pertaining to the example above, why would the variable $sandals be used as in the example, the value is 'sandals'? Shouldn't that variable be something like $shoetype?

• Test/expand my email regex

  - by Ross

  I'm really not confident with Regex, I know some basic syntax but not enough to keep me happy. I'm trying to build a regular expression to check if an email is valid. So far here's what I've got: [A-Za-z0-9._-]+@[A-Za-z0-9]+.[A-Za-z.]+ It needs to take account of periods in the username/domain and I think it works with multiple TLDs (e.g. co.uk). I'm working with the preg engine in PHP so it needs to work with that. Thanks if you can help!

• Reusing an anonymous parameter in a prepared statement

  - by Chris Lieb

  I am customizing the insert SQL generated by hibernate and have hit an issue. When Hibernate generates the query by itself, it inserts data into the first two columns of the table, but this causes a database error since all four columns of the table are non-nullable. For the insert to be performed properly, it must insert the same data into two columns of the new record. This means that I need Hibernate to bind the same data to two different parameters in the query (prepared statement) that I am writing. Is there some SQL syntax that allows me to refer to anonymous parameters bound to a prepared statement in an order different from which they are bound? Details REF_USER_PAGE_XREF ---------------------------------------- PK FK1 | NETWORK_ID | VARCHAR2(100) PK FK1 | PAGE_PATH | VARCHAR2(1000) | USER_LAST_UPDT | VARCHAR2(100) | TMSP_LAST_UPDT | DATE insert into REF_USER_ROLE_XREF( NETWORK_ID, PAGE_PATH, TMSP_LAST_UPDT, USER_LAST_UPDT) values ( ?, /* want to insert the same data here */ ?, ?, /* and here */ (select to_char(sysdate, 'DD-MON-YY') from dual) I want to insert the same data into the first and third anonymous parameters.

• Trying to create fields based on a case statement

  - by dido

  I'm having some trouble with the query below. I am trying to determine if the "category" field is A, B or C and then creating a field based on the category. That field would sum up payments field. But I'm running into error saying "incorrect syntax near keyword As". I am creating this in a SQL View. Using SQL Server 2008 SELECT r.id, r.category CASE WHEN r.category = 'A' then SUM(r.payment) As A_payments WHEN r.category = 'B' then SUM(r.payment) As B_payments WHEN r.category = 'C' then SUM(r.payment) As C_payments END FROM r_invoiceTable As r GROUP BY r.id, r.category I have data where all of the above cases should be executed because the data that I have has A,B and C Sample Data- r_invoiceTable Id --- Category ---- Payment 222 A ---- 50 444 A ---- 30 111 B ---- 90 777 C ---- 20 555 C ---- 40 Desired Output A_payments = 80, B_payments = 90, C_payments = 60

• Set The Progress Bar Over 100% C#

  - by PhaDaPhunk

  its my first time using a ProgressBar in c#. The idea is to use the ProgressBar as an health bar in a simple game. The thing is I think the bar's maximum value is 100% but i would like to give it a higher value like let's say 1000% or, not sure if it's possible, give the bar an integer value instead of a percentage. progressBar1.Increment(100); This is where I initialize the health to 100points. Even if I use this syntax: progressBar1.Increment(1000); And I subtract : progressBar1.Increment(-25); The player is loosing 1/4 of is life as if he only had 100 Health Points. Any idea how I could change the maximum Bar value? Thanks in advance.

• scripting subtlties [closed]

  - by jpmyob

  Possible Duplicates: When to use anonymous JavaScript functions? Is there any difference between var name = function() {} & function name() {} in Javascript? in javascript (and other scripting languages) what is the 'real' difference between these two syntax: a) function myFun(x) { yadda yadda } b) myFun(x) = function { yadda yadda } to a casual observer - no 'real' difference - you still call either as myFun()...and they still return the same thing, so if reference and return are identical - is it a preference or is there some difference in the code parsing engine that treats these two differently - and if so - when would you use one over the other???

• Storing pointers in multi-dimensional array

  - by sdfqwerqaz1

  My intention is to create a dynamic 3D array in C++ using pointers. MyType*** myArray; myArray = new MyType**[GRID_SIZE]; for (int i = 0; i < GRID_SIZE; ++i) { myArray[i] = new MyType*[GRID_SIZE]; for (int j = 0; j < GRID_SIZE; ++j) { myArray[i][j] = new MyType[GRID_SIZE]; } } Now this 3D array is ready to store MyType instances. What is the correct syntax needed when declaring this array if I want to store pointers to MyType instead of just MyType objects in this array?

• SQL CREATE TABLE Error

  - by Adam M-W

  Hi, I've been stuck on this one simple(ish) thing for the last 1/2 hour so I thought I might try to get a quick answer here. What exactly is incorrect about my SQL syntax, assuming I'm using mysql 5.1 CREATE TABLE 'users' ( 'id' MEDIUMINT(8) UNSIGNED NOT NULL AUTO_INCREMENT PRIMARY KEY, 'username' VARCHAR(20) NOT NULL, 'password' VARCHAR(40) NOT NULL, 'salt' VARCHAR(40) DEFAULT NULL, 'email' VARCHAR(80) NOT NULL, 'created_on' INT(11) UNSIGNED NOT NULL, 'last_login' INT(11) UNSIGNED DEFAULT NULL, 'active' TINYINT(1) UNSIGNED DEFAULT NULL, ) ENGINE InnoDB; Also, does anyone have any good tutorials about how to use Zend_Auth for complete noobs? Thanks.

• Using module include in OCaml

  - by Geoff

  In OCaml 3.11, I want to "extend" an existing module using the include directive, like so: module MyString = struct include String let trim s = ... end No problem. But now I want to expose this module's type explicitly (i.e. in a .mli file). I want something like this: module MyString : sig include String val trim : string -> string end But the include syntax is not correct because String refers to a module, not a module type (and the compiler does indeed barf). How can I refer to the module type for String here (without having write it out explicitly in a sig expression)? Thanks!

• Compiling C Source with Makefile in Windows

  - by humoeba

  I'm trying to compile a downloaded program in Windows. The program is usually run in Linux, but is programmed to also run in Windows (the code has #if defined(_WIN32)'s in it, and claims to work with borland free tools). When I try to use make from the command line, it tells me "Incorrect command line argument: -C". In the makefile, there are many lines that say "make -C" followed by a directory name. Does this syntax not work in Windows? What is a correct way to do this? Is there any way to compile this for native use in Windows with this makefile?

• Storing expression template functors

  - by UncaughtException

  Hello guys, at the moment I'm really interested in expression templates and want to code a library for writing and differentiating mathematical functions with a lambda-style syntax. At the moment, I'm able to write (_x * _x)(2); and get the correct result 4. But I would really like to do something like MathFunction f = _x * _x; f(2);, but I don't have any ideas on how to cope with the recursive expression templates on the right side. Is it possible to achieve this without using the 'auto'-Keyword instead of MathFunction or having to make the operator() virtual? Thanks for your help!
