• Play .WAV under Mono on Mac OS X (Snow Leopard)?

  - by Bob Denny

  The Mono 2.6 distribution contains System.Media.SoundPlayer, but attempts to play result in no sound (and no errors) on Mac OS X. All I can find with Google search is obscure references to ALSA. I posted to the Mono-OSX list, but there have been on replies there. I hope someone here has an answer. I think I need to tap into CoreAudio, but don't know how from Mono/C#.

• not getting a page reload when submitting a form on a page

  - by Bob Walsh

  When showing a project, the user can add a decision via a form_for and its partial. Is there some way of avoiding reloading the page and just creating the record silently? In the controller method (adddecision) I have: respond_to do |format| if @decision.save format.html { redirect_to(@project) } format.xml { head :ok } else format.html { render :action => "show" } format.xml { render :xml => decision.errors, :status => :unprocessable_entity } end I've tried redirect_to(:back) etc - still getting a page reload.

• TFS Solution build cascading to several other builds even when common components were not modified

  - by Bob Palmer

  Hey all, here is the issue I am currently trying to work through. We are using Team Foundation Server 2008, and utilizing the automated build support out of the box. We have one very large project that encompasses a number of interrelated components and web sites, each of which is set up as a Visual Studio solution file. Many of these solutions are highly interrelated since they may contain applications, or contain common libraries or shared components. We have roughly 20 or so applications, three large web sites, and about 20 components. Each solution may include projects from other solutions. For example, a solution for a console app would also include the project files for all of the components it utilizes, since we need to ensure that when someone changes a component and rebuilds it, it is reflected in all of the projects that consume that component, and we can make sure nothing was broken. We have build projects for each solution, whether that's an application, component, or web site. For this example, we will call them solutions 01, 02, and 03. These reference multiple projects (both their own core project and test projects, plus the projects relating to various components). Solution 01 has projects A, B, and C. Solution 02 has projects C, D, and E. Solution 03 has projects E, F, and G. Now, for the problem. If I modify project A, the system will end up rebuilding all three solutions. Worse, all thirty solutions reference common projects used for data access (let's call it project H). Because they all share one project in common, if I modify any solution in my stack, even if it does not touch project H, I still end up kicking off every single build script. Any thoughts on how to address this? Ideally I would only want to kick off builds where their constituant projects were directly modified - i.e in the example below, if I modified project C, I would only rebuild solutions 01 and 02. Thanks!

• NSOutlineView with Drag and Drop

  - by bob

  I read the other post here on Outlineviews and DND, but I can't get my program to work. At the bottom of this post is a link to a zip of my project. Its very basic with only an outlineview and button. I want it to receive text files being dropped on it, but something is wrong with my code or connections. I tried following Apple's example code of their NSOutline Drag and Drop, but I'm missing something. 1 difference is my program is a document based program and their example isn't. I set the File's Owner to receive delegate actions, since that's where my code to handle drag and drop is, as well as a button action. Its probably a simple mistake, so could someone please look at it and tell me what I'm doing wrong? Here is a link to the file: http://www.4shared.com/file/or1A7aHk/OutlineDragDrop.html

• jQuery style Constructors in PHP

  - by McB

  Is there a way to instantiate a new PHP object in a similar manner to those in jQuery? I'm talking about assigning a variable number of arguments when creating the object. For example, I know I could do something like: ... //in my Class __contruct($name, $height, $eye_colour, $car, $password) { ... } $p1 = new person("bob", "5'9", "Blue", "toyota", "password"); But I'd like to set only some of them maybe. So something like: $p1 = new person({ name: "bob", eyes: "blue"}); Which is more along the lines of how it is done in jQuery and other frameworks. Is this built in to PHP? Is there a way to do it? Or a reason I should avoid it?

• Aggregate Functions on subsets of data based on current row values with SQL

  - by aasukisuki

  Hopefully that title makes sense... Let's say I have an employee table: ID | Name | Title | Salary ---------------------------- 1 | Bob | Manager | 15285 2 | Joe | Worker | 10250 3 | Al | Worker | 11050 4 | Paul | Manager | 16025 5 | John | Worker | 10450 What I'd like to do is write a query that will give me the above table, along with an averaged salary column, based on the employee title: ID | Name | Title | Salary | Pos Avg -------------------------------------- 1 | Bob | Manager | 15285 | 15655 2 | Joe | Worker | 10250 | 10583 3 | Al | Worker | 11050 | 10583 4 | Paul | Manager | 16025 | 15655 5 | John | Worker | 10450 | 10583 I've tried doing this with a sub-query along the lines of: Select *, (select Avg(e2.salary) from employee e2 where e2.title = e.title) from employee e But I've come to realize that the sub-query is executed first, and has no knowledge of the table alias'd e I'm sure I'm missing something REALLY obvious here, can anyone point me in the right diretion?

• Custom Build Step Paths Between x86 and x64 in Visual Studio

  - by Bob Somers

  For reference, I'm using Visual Studio 2010. I have a custom build step defined as follows: if exist "$(TargetDir)"server.dll copy "$(TargetDir)"server.dll "c:\program files (x86)\myapp\server.dll" This works great on my desktop, which is running 64-bit Windows. However, when I build on my laptop, c:\Program Files (x86)\ doesn't exist because it's running 32-bit Windows. I'd like to put in something that will work between both editions of Windows, since the project files are under version control and it's a real pain to change the paths every time I work on my laptop. If this were a *nix environment I'd just create a symlink and be done with it. Any ideas?

• Odd DOM Problem with Firefox

  - by Bob

  Hello. I'm experiencing an odd problem when trying to navigate through a table's rows and cells in a while loop using javascript. I'm using Firefox 3.5.7 on Win7 with Firebug enabled. I have this markup: <table> <tbody> <tr id='firstRow'><td>a</td><td>b</td><td>c</td></tr> <tr><td>a</td><td>b</td><td>c</td></tr> <tr><td>a</td><td>b</td><td>c</td></tr> </tbody> </table> And this javascript: var row = document.getElementById('firstRow'); console.log(row); // Row call 1 while (row) { console.log(row); // Row call 2 row = row.nextSibling; } The problem I'm having is that on the line commented "Row call 1", Firebug is outputting <tr id='firstRow'> as expected. However, in the while loop, Firebug is giving me <tr id='firstRow'> <TextNode textContent="\n"> It is giving me different output for the exact same row, even immediately after the while loop begins executing and nothing else touched the row. For subsequent rows, it of course does not have id='firstRow' as an attribute. The bigger problem this is giving me is that if I'm in the while loop, and I want to access a particular cell of the current row using row.cells[0], Firebug will give me an error that row.cells is undefined. I want to know if someone could shed some light on this situation I am experiencing.

• Cross Domain Post - Losing POST Data

  - by Tomas Beblar

  I have 2 servers, both running R2 / IIS7 / ASP Classic sites (can't get around any of that) Server A is making the follow calls: Dim objXMLHTTP, xml Set xml = Server.CreateObject("Msxml2.ServerXmlHTTP.6.0") xml.Open "POST", templateName, false xml.setRequestHeader "Content-Type", "application/xml" xml.Send variables Where the templateName is the URL of Server B (It's an email template) ... and variables are a name value pair string like a query string password=myPassword&customerEmail=Dear+Bob,.... Server B receives the POST but all the POST data (password=myPassword&customerEmail=Dear+Bob,....) is missing from the POST password = Request.Form("templatePassword") customerEmail = Request.Form("RackAttackCustomerEmail") The above values are all empty. Here's the kicker. This all worked on our old servers (Windows Server 2003, IIS 6) But when we migrated over, this stopped working correctly. My question is: What would cause the POST data to be dropped in IIS 7 when it all worked in IIS 6? I've done about 3 days of research into this trying many different things and nothing has worked. The POST data is just gone.

• How large a role does subjectiveness play in programming?

  - by Bob

  I often read about the importance of readability and maintainability. Or, I read very strong opinions about which syntax features are bad or good. Or discussions about the values of certain paradigms, like OOP. Aside from that, this same question floats about in my mind whenever I read debates on SO or Meta about subjective questions. Or read questions about best practices and sometimes find myself or others disagreeing. What role does subjectiveness play within the programming realm? Sometimes I think it plays a large role. Software developers are engineers in a way, but also people. A large part of programming is dealing with code that's human readable. This is very different from Math or Physics or other disciplines with very exact and structured rules. Here the exact structure and rules are largely up in the air, changeable on a whim, and hence the amount of languages in existence. And one person may find one language very readable, and another person may find their own language the most comforting. The same with practices. One person may not like certain accepted practices. I myself find splitting classes into different files very unreadable, for instance. But, I can't say rules haven't helped in general. Certain practices have and do make life easier. And new languages have given rise to syntax and structure that make life easier. There's certainly been a progression towards code that is easier to read and maintain even given a largely diverse group of people. So maybe these things aren't as subjective as I thought. It reminds me, in a way, of UI design. Certainly it's subjective, but then there's an entire discipline involved in crafting good UI and it tends to work. Is there something non-subjective about the ideas behind maintainability, readability, and other best practices? Is there something tangible to grasp when one develops a new language or thinks of new practices?

• rails Creating a model instance automatically when another is created

  - by bob

  Hello I have a user model and a ratings model. Whenever a new user is created I want to create a new feedback model with it automatically. Each user model has one feedback model and each feedback model has many ratings. My Classes class User < ActiveRecord::Base end class Feedback < ActiveRecord::Base belongs_to :user has_many :ratings end class Rating < ActiveRecord::Base belongs_to :feedback end My database tables -user doesn't have anything special -feedback has user_id. This user_id should be the same as the user that has just been created. For example, user_id of 1 is created, then a feedback model should be created that belongs to user_id of 1. So the user_id column in the feedback database will also be 1. - Rating has a feedback_id and a user_id the user_id in this case is the id of the person who submitted the rating. I am having it assigned through the build command. I believe my process is correct here. The Goal The goal is to have each user have a feedback table that has many ratings from other users. So if someone goes to the feedback page, they will see all the ratings given and by who. Is there a better way to approach this? How do you create a model of feedback with the same id as the user being created right when a new user is created. The idea is that when a user is created a feedback is created associated with that user so people can then go to http://localhost:3000/users/1/feedback/ and submit new ratings. I'm trying to bypass having a user rate another user with just a ratings model because I'm not sure how to do it.

• Clipping the caret in a C# program

  - by Bob Sammers

  I'm creating a WinForms control in C# (using VS2008, .net 3.5) which allows text input. I've imported the necessary Win32 API functions from User32.dll for displaying the normal Windows caret and these are all working fine, but it's not displaying exactly how I'd like it. Text is displayed on the control with a blank border and I use Graphics.SetClip() to leave this margin clear. I want the caret to be clipped to the same region, but since I don't paint it and there's no obvious API function to set a clipping region, I can't see any way of doing this. Have I missed anything obvious? The caret is clipped inside the control in which it is drawn. I'm therefore aware that one solution could be to place the text in a separate sub-control with no border. However, if there's a simpler way than redesigning this part of the control, I'd like to look for that first. Thanks in advance for any help!

• Generating MySQL UPDATE statements containing BLOB image data

  - by Bob

  I'm trying to write an SQL statement that will generate an SQL script that will update a BLOB field with an IMAGE being selected from the database. This is what I have: select concat( 'UPDATE `IMAGE` SET THUMBNAIL = ', QUOTE( THUMBNAIL ), ' WHERE ID = ', ID, ';' ) as UPDATE_STATEMENT from IMAGE; In the above, THUMBNAIL is a BLOB field containing raw image data. When I run the resulting script I get the following error: ERROR at line 2: Unknown command '\\'. I first tried this without the QUOTE() function, like so: select concat( 'UPDATE `IMAGE` SET THUMBNAIL = \'', THUMBNAIL, '\' WHERE ID = ', ID, ';' ) as UPDATE_STATEMENT from IMAGE; Running the resulting script produces this error: ERROR at line 2: Unknown command '\0'. What is the proper function to apply to this BLOB field in the select, so the UPDATE statements will work? If context is required, I'm looking to migrate thumbnails generated on one server to another server for certain image IDs only. I would use mysqldump, but I don't want to clobber the entire table. Any help is greatly appreciated!

• How can I set the line style of a specific cell in a QTableView?

  - by Bob Nelson

  I am working with a QT GUI. I am implementing a simple hex edit control using a QTableView. My initial idea is to use a table with seventeen columns. Each row of the table will have 16 hex bytes and then an ASCII representation of that data in the seventeenth column. Ideally, I would like to edit/set the style of the seventeenth column to have no lines on the top and bottom of each cell to give the text a free flowing appearance. What is the best way to approach this using the QTableView?

• log4j performance

  - by Bob

  Hi, I'm developing a web app, and I'd like to log some information to help me improve and observe the app. (I'm using Tomcat6) First I thought I would use StringBuilders, append the logs to them and a task would persist them into the database like every 2 minutes. Because I was worried about the out-of-the-box logging system's performance. Then I made some test. Especially with log4j. Here is my code: Main.java public static void main(String[] args) { Thread[] threads = new Thread[LoggerThread.threadsNumber]; for(int i = 0; i < LoggerThread.threadsNumber; ++i){ threads[i] = new Thread(new LoggerThread("name - " + i)); } LoggerThread.startTimestamp = System.currentTimeMillis(); for(int i = 0; i < LoggerThread.threadsNumber; ++i){ threads[i].start(); } LoggerThread.java public class LoggerThread implements Runnable{ public static int threadsNumber = 10; public static long startTimestamp; private static int counter = 0; private String name; public LoggerThread(String name) { this.name = name; } private Logger log = Logger.getLogger(this.getClass()); @Override public void run() { for(int i=0; i<10000; ++i){ log.info(name + ": " + i); if(i == 9999){ int c = increaseCounter(); if(c == threadsNumber){ System.out.println("Elapsed time: " + (System.currentTimeMillis() - startTimestamp)); } } } } private synchronized int increaseCounter(){ return ++counter; } } } log4j.properties log4j.logger.main.LoggerThread=debug, f log4j.appender.f=org.apache.log4j.RollingFileAppender log4j.appender.f.layout=org.apache.log4j.PatternLayout log4j.appender.f.layout.ConversionPattern=%d{ABSOLUTE} %5p %c{1}:%L - %m%n log4j.appender.f.File=c:/logs/logging.log log4j.appender.f.MaxFileSize=15000KB log4j.appender.f.MaxBackupIndex=50 I think this is a very common configuration for log4j. First I used log4j 1.2.14 then I realized there was a newer version, so I switched to 1.2.16 Here are the figures (all in millisec) LoggerThread.threadsNumber = 10 1.2.14: 4235, 4267, 4328, 4282 1.2.16: 2780, 2781, 2797, 2781 LoggerThread.threadsNumber = 100 1.2.14: 41312, 41014, 42251 1.2.16: 25606, 25729, 25922 I think this is very fast. Don't forget that: in every cycle the run method not just log into the file, it has to concatenate strings (name + ": " + i), and check an if test (i == 9999). When threadsNumber is 10, there are 100.000 loggings and if tests and concatenations. When it is 100, there are 1.000.000 loggings and if tests and concatenations. (I've read somewhere JVM uses StringBuilder's append for concatenation, not simple concatenation). Did I missed something? Am I doing something wrong? Did I forget any factor that could decrease the performance? If these figures are correct I think, I don't have to worry about log4j's performance even if I heavily log, do I?

• MinGW and "declaration does not declare anything"

  - by Bob Somers

  I'm working on converting a Linux project of mine to compile on Windows using MinGW. It compiles and runs just fine on Linux, but when I attempt to compile it with MinGW it bombs out with the following error message: camera.h:11: error: declaration does not declare anything camera.h:12: error: declaration does not declare anything I'm kind of baffled why this is happening, because I'm using the same version of g++ (4.4) on both Linux and Windows (via MinGW). The contents of camera.h is absurdly simple. Here's the code. It's choking on lines 11 and 12 where float near; and float far; are defined. #include "Vector.h" #ifndef _CAMERA_H_ #define _CAMERA_H_ class Camera{ public: Vector eye; Vector lookAt; float fov; float near; float far; }; #endif Thanks for your help.

• Does Java 6 open a default port for JMX remote connections?

  - by Bob Cross

  My specific question has to do with JMX as used in JDK 1.6: if I am running a Java process using JRE 1.6 with com.sun.management.jmxremote in the command line, does Java pick a default port for remote JMX connections? Backstory: I am currently trying to develop a procedure to give to a customer that will enable them to connect to one of our processes via JMX from a remote machine. The goal is to facillitate their remote debugging of a situation occurring on a real-time display console. Because of their service level agreement, they are strongly motivated to capture as much data as possible and, if the situation looks too complicated to fix quickly, to restart the display console and allow it to reconnect to the server-side. I am aware the I could run jconsole on JDK 1.6 processes and jvisualvm on post-JDK 1.6.7 processes given physical access to the console. However, because of the operational requirements and people problems involved, we are strongly motivated to grab the data that we need remotely and get them up and running again. EDIT: I am aware of the command line port property com.sun.management.jmxremote.port=portNum The question that I am trying to answer is, if you do not set that property at the command line, does Java pick another port for remote monitoring? If so, how could you determine what it might be?

• DOM and Javascript

  - by Bob Smith

  I let a user reconfigure the location of a set of rows in a table by giving them ability to move them up and down. The changes are done by swapping nodes in the DOM. After the user has moved rows around, when I do a view source, I see the HTML in the original state (before the user made any changes). Can someone explain why that is? My understanding was when we do any DOM operations, the underlying HTML will be changed as well. EDIT: Does that mean on the server side, when attempt to get the state after user's changes, I will be able to get what I need? I am using C#/ASP.NET. Could it be because this is a HTML table (not ASP.NET Server control), that it's not maintaining the state of the changes?
