• C# method contents regex validation

  - by user258651

  I need to validate the contents of a C# method. I do not care about syntax errors. I do care about characters that will invalidate parsing of the rest of the code. For example: method() { /* valid comment */ /* <-- bad for (i..) { } for (i..) { <-- bad } I need to validate/fix any non-paired characters. This includeds /* */, { }, and maybe others. How should I go about this?

• Articles about replication schemes/algorithms?

  - by jkff

  I'm designing an hierarchical distributed system (every node has zero or more "master" nodes to which it propagates its current data). The data gets continuously updated and I'd like to guarantee that at least N nodes have almost-current data at any given time. I do not need complete consistency, only eventual consistency (t.i. for any time instant, the current snapshot of data should eventually appear on at least N nodes. It is tricky to define the term "current" here, but still). Nodes may fail and go back up at any moment, and there is no single "central" node. O overflowers! Point me to some good papers describing replication schemes. I've so far found one: Consistency Management in Optimistic Replication Algorithms

• Grouping a generic list via LINQ in VB.NET

  - by CD Smith

  I need to take a collection and group it via Linq but all the examples I've seen fail in some manner or other with some syntax difference that I can't quite lick. My collection: Dim a As New List(Of ProcessAlert) a.Add(New ProcessAlert("0000112367", "[email protected]", "Alert", 2)) a.Add(New ProcessAlert("0000112367", "[email protected]", "Document", 2)) a.Add(New ProcessAlert("0000112367", "[email protected]", "Note", 2)) a.Add(New ProcessAlert("0000112367", "[email protected]", "Alert", 1)) a.Add(New ProcessAlert("0000112367", "[email protected]", "Document", 1)) a.Add(New ProcessAlert("0000112367", "[email protected]", "Note", 1)) Return a I need to turn this collection into a simple way to give this final outcome: "[email protected]", "Alert, Document, Note" "[email protected]", "Alert, Document, Note" Here's the definition of the ProcessAlert class: Public Class ProcessAlert Public LoanNumber As String Public EmailAddress As String Public AlertType As String Public AlertMethodID As Byte End Class Thanks in advance, CD

• jquery get the index of a row?

  - by KnockKnockWhosThere

  I'm trying to write a function that will do something if the the row index is 0, and then something else if the row index is greater than 0. The zero part is working, but I can't figure out the syntax for rows that have an index greater than 0. For the tr[0] row, I'm doing this: if($("#mytable > tbody > tr ").index(0)) { ... I tried: if($("#mytable > tbody > tr ").index() > 0 ) { But, that didn't work?

• Error including image in Latex

  - by euphoria83

  I am getting the following error while compiling my Latex File : ! LaTeX Error: Cannot determine size of graphic in tree.jpg (no BoundingBox). Why do I get this error ? What has this to do with an .eps file ? Infact, I could compile it fine with MacTex on my machine. But when I submit it online to a scientific journal for publication, it compiles it on the server and sends me the resultant PDF which as all these error that prevent it from compiling. I am using the following syntax for including the images : \begin{figure}[!h] \begin{center} \scalebox{0.45}{ \includegraphics{tree.jpg}} \end{center} \caption{\small A sample} \label{tree} \end{figure} What should I do ? Could it be that their server is using an old compiler ? UPDATE : It finally worked. I converted the first image to PDF and the compilation happened perfectly. I guess it used the bounding box value from that PDF and applied it to all images.

• Powershell and some simple string manipulation

  - by Pat

  need some help with building a powershell script to help with some basic string manipulation. I know just enough powershell to get in trouble, but can't figure out the syntax or coding to make this work. I have a text file that looks like this - Here is your list of servers: server1 server2.domain.local server3 Total number of servers: 3 I need to take that text file and drop the first and last lines (Always first and last.) Then I need to take every other line and basically turn it into a CSV file. The final output should be a text file that looks like this - server1,server2.domain.local,server3 Any suggestions on where to start? Thanks!

• Why doesn't a LinkButton work with a table as it's content?

  - by Telos

  Using ASP.NET 3.5, you can create a LinkButton then define content inside of it. It works fine if I have div tags or any kind of text or anything, but if I use a table the click doesn't actually post back for some reason. This should take you to google (you'll get an error there but it should still go) for instance: <asp:LinkButton ID="lbTest" PostBackUrl="http://www.google.com" runat="server"> <table> <tr> <td>Test</td> <td>col2</td> <td>col3</td> </tr> </table> </asp:LinkButton> I could work around it by building a "table" with divs I guess, but I hate formatting with divs.

• INSERT INTO ... SELECT FROM ... ON DUPLICATE KEY UPDATE

  - by dnagirl

  I'm doing an insert query where most of many columns would need to be updated to the new values if a unique key already existed. It goes something like this: INSERT INTO lee(exp_id, created_by, location, animal, starttime, endtime, entct, inact, inadur, inadist, smlct, smldur, smldist, larct, lardur, lardist, emptyct, emptydur) SELECT id, uid, t.location, t.animal, t.starttime, t.endtime, t.entct, t.inact, t.inadur, t.inadist, t.smlct, t.smldur, t.smldist, t.larct, t.lardur, t.lardist, t.emptyct, t.emptydur FROM tmp t WHERE uid=x ON DUPLICATE KEY UPDATE ...; //update all fields to values from SELECT, except for exp_id, created_by, location, animal, starttime, endtime I'm not sure what the syntax for the UPDATE clause should be. How do I refer to the current row from the SELECT clause?

• Identifying PHP unused variables (in Emacs)?

  - by Roberto Aloi

  Is it somehow possible to identify unused variables in a PHP file in Emacs? With other languages, this is possible by using tools such as flymake. I've already enabled Flymake to show syntax errors for my PHP files on the fly, but still it's frustrating that PHP logic errors are sometimes due to situations like: <?php $foo = whatever(); $bar = something($fo); ... Note the typo on $foo that will contribute to the developer's headache and to his exorbitant use of coffee.

• nhibernate : mapping to column other than primary key

  - by frosty

  I have the following map. My intention is for the order.BasketId to map to orderItem.BasketId. Tho when i look at the sql i see that it's mapping order.Id to orderItem.BasketId. How do i define in my order map which order property to map against basketId. It seems to default to the primary key. <property name="BasketId" column="Basket_ID" type="Int32"/> <set name="OrderItems" table="item_basket_contents" generic="true" inverse="true" > <key column="Basket_ID" /> <one-to-many class="EStore.Domain.Model.OrderItem, EStore.Domain"/> </set>

• Python del() built-in can't be used in assignment?

  - by emcee

  I noticed a problem when I was trying to use del in a lambda to thin out a list of threads to just those running: map(lambda x: del(x) if not x.isAlive() else x, self.threads) Ignore for a second that this doesn't do anything, I'm just fooling around with map, reduce, and lambda. This fails with a syntax error at del(x). With some messing around, I think the problem is del() doesn't return a value. For example, this fails with the same error: b = 5 x = del(b) This doesn't, however: def rmThis(x): del(x) Which means I'm using this workaround: map(lambda x: rmThis(x) if not x.isAlive() else x, self.threads) So is the limitation just because del() doesn't return a value? Why not? I'm using python 2.6.2

• Core Data table record count

  - by user339633

  I have an entity called Person and it has a relationship called participatingGames, to another entity called GameParticipant. I (apparently) can retrieve the number of matches in the GameParticipant entity using this simple code in the Person object I created from the entity in the model: [self.participatingGames count]; However, I'd just like to retrieve the number of Person records and one might guess the syntax for this is just as simple. I have lots of books including those by Jeff LaMarche, but those sources and what I find around here make me wonder if I need to set up a fetchedResultsController just to know the count of some entity. My background is in SQL, so of course it seems odd that what would take 15 seconds to code in any other environment seems like such a well-guarded secret in Core Data. I'm using iPhone SDK 3.1.4 under OSX 10.5.8 Suggestions?

• Pick Return Values of Stored Procedure

  - by Juergen

  Hi, I have a stored procedure that returns a result with 250!!! columns. But I only need 3 out of the 250. I want to call the SP and put only the 3 column values in a temp table. I don't want to define a temp table with 250 columns! This is how I would like to do it, but this doesn't work of course: create #myTempTable (id int, value1 int, value2 int) insert into #myTempTable exec myBigFatStoredProc Can it be done anyhow?

• Refer to te current directory in a shell script

  - by One Two Three

  How do I refer to the current directory in a shell script So I have this script which calls another script in the same directory #! /bin/sh #Call the other script ./foo.sh # do something ... For this I got ./foo.sh: No such file or directory So I changed it to: #! /bin/sh #Call the other script foo.sh # do something ... But this would call the foo script which is, by default, in the PATH. This is not what I want. So the question is, what's the syntax of doing './` in a shell script?

• How do I get a right outer join in L2E?

  - by Dan

  I have two tables that I set up through the VS Entity Data Model Diagram tool. I'm trying to do a right outer join and it doesn't return results from the 2nd table. I have set up a 0..1 to MANY relationship from the diagram tool. When I run a Linq-To-Entities query, it still defaults to an INNER JOIN. From my understanding of entities, if I set up the relationship using VS, when I join the tables, it should automagically figure out the join syntax based on the relationship I supply. It doesn't seem to be doing that. I am using EF v1 (not Linq-to-Sql). Query I'm running: from s in SomeTable join t in SomeOtherTable on s.ID equals t.ID select new { s.MyFieldName, t.MyOtherFieldName }

• MySQL or SQL Server

  - by user203708

  I'm creating an application that I want to run on either MySQL or SQL Server (not both at the same time) I've created two PHP classes DatabaseMySQL and DatabaseSQLSVR and I'd like my application to know which database class to use based on a constant set up at install. define(DB_TYPE, "mysql"); // or "sqlsrv" I'm trying to think of the best way to handle this. My thought is to do an "if else" wherever I instantiate the database: $db = (DB_TYPE == "mysql") ? new DatabaseMySQL : new DatabaseSQLSVR; I know there has to be a better way of doing this though. Suppose I want to add a third database type later; I'll have to go and redo all my code. Yuk!! Any help would be much appreciated. Thank

• Problem with mysql query to replace a string

  I've used mysql's update replace function before, but even though I think I'm following the same syntax, I can't get this to work. Here's what I'm trying to do: UPDATE contained_widgets SET preference_values = REPLACE(preference_values, '<li><a_href="/enewsletter"><span class="not-tc">eNewsletter</span></a></li>', '<li><a_href="/enewsletter"><span class="not-tc">eNewsletter</span></a></li> <li> <a_href="/projects"><span class="not-tc">Projects</span></a></li>'); Query OK, 0 rows affected (0.00 sec) Rows matched: 77 Changed: 0 Warnings: 0 I don't see what I'm missing. Any help is appreciated. I edited "a " to "a_" because the site thinks I'm posting spam links otherwise.

• Ruby on Rails: attr_accessor for submodels

  - by williamjones

  I'm working with some models where a lot of a given model's key attributes are actually stored in a submodel. Example: class WikiArticle has_many :revisions has_one :current_revision, :class_name => "Revision", :order => "created_at DESC" end class Revision has_one :wiki_article end The Revision class has a ton of database fields, and the WikiArticle has very few. However, I often have to access a Revision's fields from the context of a WikiArticle. The most important case of this is probably on creating an article. I've been doing that with lots of methods that look like this, one for each field: def description if @description @description elsif current_revision current_revision.description else "" end end def description=(string) @description = string end And then on my save, I save @description into a new revision. This whole thing reminds me a lot of attr_accessor, only it doesn't seem like I can get attr_accessor to do what I need. How can I define an attr_submodel_accessor such that I could just give field names and have it automatically create all those methods the way attr_accessor does?

• Hide buttons when making a screenshot UIGraphicsBeginImageContextWithOptions

  - by Jan

  is there a way to hide specific buttons (IBAction) when making a screenshot with UIGraphicsBeginImageContextWithOptions ? I'm using the code below: // Define the dimensions of the screenshot you want to take (the entire screen in this case) UIGraphicsBeginImageContextWithOptions(self.view.bounds.size, self.view.opaque, 0.0); [self.view.layer renderInContext:UIGraphicsGetCurrentContext()]; UIImage *sourceImage = UIGraphicsGetImageFromCurrentImageContext(); UIGraphicsEndImageContext(); //now we will position the image, X/Y away from top left corner to get the portion we want UIGraphicsBeginImageContextWithOptions(self.view.bounds.size, self.view.opaque, 0.0); [sourceImage drawAtPoint:CGPointMake(0, -20)]; UIImage *croppedImage = UIGraphicsGetImageFromCurrentImageContext(); UIGraphicsEndImageContext(); UIImageWriteToSavedPhotosAlbum(croppedImage,nil, nil, nil); Thank you for your answer!

• Java multiline string

  - by skiphoppy

  Coming from Perl, I sure am missing the "here-document" means of creating a multi-line string in source code: $string = <<"EOF" # create a three line string text text text EOF In Java I have to have cumbersome quotes and plus signs on every line as I concatenate my multiline string from scratch. What are some better alternatives? Define my string in a properties file? Edit: Two answers say StringBuilder.append() is preferable to the plus notation. Could anyone elaborate as to why they think so? It doesn't look more preferable to me at all. I'm looking for away around the fact that multiline strings are not a first-class language construct, which means I definitely don't want to replace a first-class language construct (string concatenation with plus) with method calls. Edit: To clarify my question further, I'm not concerned about performance at all. I'm concerned about maintainability and design issues.

• javascript. is it posible for one member of an object to access another member of that object withou

  - by joox

  For example: var myObj={ myValue="hola", asMember=function(){ alert( this.myValue ); } }; myObj.asMember(); // will work fine var asGlobal=myObj.asMember; // global alias for that member function asGlobal(); // won't work in javascript (will work in AS3, but i need js now) So the question is, can I rewrite asMember so that it could be called by global alias and without mentioning myObj at all? It's understood that if I define it: asMember=function(){ alert( myObj.myValue ); } it will work, but in my case, mentioning myObj is not acceptable even inside the function itself (because myObj may be reassigned later, but asGlobal won't change and should keep working)

• How to auto create a JMS topic/queue on JBoss in a portable and per-application way?

  It's simple: I have an MDB and an EJB that sends messages to a topic (or queue). JBoss complains that the topic is not bound to the JNDI context. I want to have the topic/queue to be automatically created at best, or at least to have a standard way to define it, per application (say, in ejb-jar/META-INF) this question and this blogpost show us how to do it in an application server specific way. This surely works, but: I want to use the @MessageDriven annotation I want the setting not to be global for the application server I want the setting to be portable

• Why does it work

  - by A-ha

  Guys I've asked few days ago a question and didn't have really time to check it and think about it, but now I've tried one of the solutions and I can't understand why does it work? I mean why destructor is called at the end of line like this: #include "stdafx.h" #include "coutn.h" #define coutn coutn() int _tmain(int argc, _TCHAR* argv[]) { coutn << "Line one " << 1;//WHY DTOR IS CALLED HERE coutn << "Line two " << " and some text."; return 0; } I assume that it has something to do with lifetime of an object but I'm not sure what and how. As I think of it there are two unnamed objects created but they do not go out of scope so I can't understand for what reason is dtor called. Thank you.

• Java array assignment (multiple values)

  - by Danny King

  Hello, I have a Java array defined already e.g. float[] values = new float[3]; I would like to do something like this further on in the code: values = {0.1f, 0.2f, 0.3f}; But that gives me a compile error. Is there a nicer way to define multiple values at once, rather than doing this?: values[0] = 0.1f; values[1] = 0.2f; values[2] = 0.3f; Thanks!
