  • PHP5.3 is not working with MySQL5.1 IIS7 Times out

    - by Thorn007
    I have set up PHP5.3, MySQL5.1, and IIS7 on Window 7 but php doesn't want to work with MySQL. I'm assuming it is a configuration error or an incomplete install on my part. MySQL5.1 is working PHP5.3 is working, phpinfo() shows info and that i have enabled MySQL IIS is setup and using fastCgiModule to run PHP IIS registers php.ini updates port 3306 is firewall free and open to the world php.ini is configured correctly I have added c:\php to the Windows systems PATH In the past I remember moving a file, libmysql.dll, to System32 but I doesn't look like that come with php5.3.1, as the driver comes built in now http://us3.php.net/manual/en/mysqlnd.install.php. (This has been giving me so much trouble I have been documenting my findings on my blog as http://inteldesigner.com/2010/code/having-problems-getting-php5-3-to-work-with-mysql5-1 ) NEED: I need to install PHP manually, don't want to use the quick installer or an older version I need to get PHP5.3 to work with MySQL5.1 so i can install Wordpress2.9 and Drupal7a Any links or suggestion would be great, I have already done everything on the iis web site, nothing is working. I'm guessing they have not updated for new software. BUGS/SOLUTION: The solution is here: http://bugs.php.net/bug.php?id=50172 thanks go to don.raman on the iis.net forums http://forums.iis.net/p/1164911/1933894.aspx SYMPTOMS: The php function mysql_connect() in conjunction with php5.3 locks up sever and returns error 500.

  • c# Properties.Settings.Default Doesn't work as expected

    - by Jack
    I've been working on a program to automate my backup checks with LogMeIn backup (a windows forms based program). I now need a way to store user settings, to save information easily. I've never worked with the Application/User settings that is somewhat "built-in" - and decided to try it, but ran into problems. I added four settings for now: IncludeCriteria (Specialized.StringCollection) ExcludeCriteria (Specialized.StringCollection) ReportPath (string) ReportType (int) But the behavior doesn't act as expected (go figure). After saving some values in my program, I go back into edit/view my settings values using the VS 2008 settings editor. None of my values are stored. While I think this may be because those values are just default values, wouldn't that be where they can be stored/read/changed? Here is my load form code (still very unrefined): private void setupForm() { txtPath.Text = BackupReport.Properties.Settings.Default.ReportPath == null ? "" : BackupReport.Properties.Settings.Default.ReportPath; if (BackupReport.Properties.Settings.Default.ReportType == 0) { radioHTML.Checked = true; } else radioExcel.Checked = true; if (BackupReport.Properties.Settings.Default.IncludeCriteria.Count > 0) { listIncludeCriteria.DataSource = Properties.Settings.Default.IncludeCriteria; //foreach (string s in Properties.Settings.Default.IncludeCriteria) // listIncludeCriteria.Items.Add(s); } if (BackupReport.Properties.Settings.Default.ExcludeCriteria.Count > 0) { listExcludeCriteria.DataSource = BackupReport.Properties.Settings.Default.ExcludeCriteria; //foreach (string s in Properties.Settings.Default.ExcludeCriteria) // listExcludeCriteria.Items.Add(s); } } listIncludeCriteria is just a listbox. When the user saves I call this method: private void saveSettings() { //var settings = BackupReport.Properties.Settings; if (txtPath.Text != "") { BackupReport.Properties.Settings.Default.ReportPath = txtPath.Text; } if (listIncludeCriteria.Items.Count > 0) { //BackupReport.Properties.Settings.Default.IncludeCriteria = (StringCollection)listIncludeCriteria.Items.AsQueryable(); foreach (var i in listIncludeCriteria.Items) { if (!isIncludeDuplicate(i.ToString())) BackupReport.Properties.Settings.Default.IncludeCriteria.Add(i.ToString()); } } if (listExcludeCriteria.Items.Count > 0) { //BackupReport.Properties.Settings.Default.ExcludeCriteria = (StringCollection)listExcludeCriteria.Items.AsQueryable(); foreach (var i in listExcludeCriteria.Items) { if (!isExcludeDuplicate(i.ToString())) Properties.Settings.Default.ExcludeCriteria.Add(i.ToString()); } } if (radioExcel.Checked == true) BackupReport.Properties.Settings.Default.ReportType = 1; else BackupReport.Properties.Settings.Default.ReportType = 0; BackupReport.Properties.Settings.Default.Save(); //Properties.Settings.Default.Save(); this.DialogResult = DialogResult.OK; this.Close(); } The wierd thing is when the form loads, the path I put in the first time seems to come up (ReportPath) - even the listBoxes are populated with a bunch of crap I put in - yet I cant find these values anywhere. Any help would be appreciated! Josh

  • Featureful commercial text editors?

    - by wrp
    I'm willing to buy tools if they add genuine value over a FOSS equivalent. One thing I wouldn't mind having is an editor with the power of Emacs, but made more user-friendly. There seem to be several commercial editors out there, but I can't find much discussion of them online. Maybe it's because the kind of people who use commercial software don't have time to do much blogging. ;-) If you have used any, what was your evaluation? I'd especially like to hear how you would compare them to Emacs. I'm thinking of editors like VEDIT, Boxer, Crisp, UltraEdit, SlickEdit, etc. To get things started, I tried EditPad Pro because I needed something on a Win98SE box. I was attracted by its powerful support for regexps, but I didn't use it for long. One annoyance was that find-in-files was only available in a separate product you had to buy. The main problem, though, was stability. It sometimes hung and I lost a few files because it corrupted them while editing. After a couple weeks, I found that I was avoiding using it, so I just uninstalled. Edit: Ah...I need to remove some ambiguity. With reference to Emacs, "power" often means its potential for customization. This malleability comes from having an architecture in which most of the functionality is written in a scripting language that runs on a compiled core. Emacs (with elisp) is by far the most widely known such system among home users, but there have been other heavily used editors such as Freemacs (MINT), JED (S-Lang), XEDIT (Rexx), ADAM (TPU), and SlickEdit (Slick-C). In this case, by "power" I'm not referring to extensibility but to realized features. There are three main areas which I think a commercial text editor might be an improvement over Emacs: Stability The only apps I regularly use on Linux that give me flaky behavior are Emacs, Gedit, and Geany. On Windows, I like the look and features of Notepad++, but I find it extremely unstable, especially if I try to use the plugins. Whatever I happen to be doing, I'm using some text editor practically all day long. If I could switch to an editor that never gave me problems, it would definitely lower my stress level. Tools When I started using Emacs, I searched the manual cover to cover to gleam ideas for clever, useful things I could do with it. I'd like to see lots of useful features for editing code, based on detailed knowledge of what the system can do and the accumulated feedback of users. Polish The rule of threes goes that if you develop something for yourself, it's three times harder to make it usable in-house, and three times harder again to make it a viable product for sale. It's understandable, but free software development doesn't seem to benefit from much usability testing. BTW, texteditors.org is a fantastic resource for researching text editors.

  • Opinions on sensor / reading / alert database design

    - by Mark
    I've asked a few questions lately regarding database design, probably too many ;-) However I beleive I'm slowly getting to the heart of the matter with my design and am slowly boiling it down. I'm still wrestling with a couple of decisions regarding how "alerts" are stored in the database. In this system, an alert is an entity that must be acknowledged, acted upon, etc. Initially I related readings to alerts like this (very cut down) : - [Location] LocationId [Sensor] SensorId LocationId UpperLimitValue LowerLimitValue [SensorReading] SensorReadingId Value Status Timestamp [SensorAlert] SensorAlertId [SensorAlertReading] SensorAlertId SensorReadingId The last table is associating readings with the alert, because it is the reading that dictate that the sensor is in alert or not. The problem with this design is that it allows readings from many sensors to be associated with a single alert - whereas each alert is for a single sensor only and should only have readings for that sensor associated with it (should I be bothered that the DB allows this though?). I thought to simplify things, why even bother with the SensorAlertReading table? Instead I could do this: [Location] LocationId [Sensor] SensorId LocationId [SensorReading] SensorReadingId SensorId Value Status Timestamp [SensorAlert] SensorAlertId SensorId Timestamp [SensorAlertEnd] SensorAlertId Timestamp Basically I'm not associating readings with the alert now - instead I just know that an alert was active between a start and end time for a particular sensor, and if I want to look up the readings for that alert I can do. Obviously the downside is I no longer have any constraint stopping me deleting readings that occurred during the alert, but I'm not sure that the constraint is neccessary. Now looking in from the outside as a developer / DBA, would that make you want to be sick or does it seem reasonable? Is there perhaps another way of doing this that I may be missing? Thanks. EDIT: Here's another idea - it works in a different way. It stores each sensor state change, going from normal to alert in a table, and then readings are simply associated with a particular state. This seems to solve all the problems - what d'ya think? (the only thing I'm not sure about is calling the table "SensorState", I can't help think there's a better name (maybe SensorReadingGroup?) : - [Location] LocationId [Sensor] SensorId LocationId [SensorState] SensorStateId SensorId Timestamp Status IsInAlert [SensorReading] SensorReadingId SensorStateId Value Timestamp There must be an elegant solution to this!

  • MediaElement fails after several plays.

    - by basilkot
    Hi! I have a problem with MediaElement control. I've put six MediaElements on my form, then I start them and change played files by timer. After several times, these elements stop playing. Here is the sample XAML: <Grid> <Grid.RowDefinitions> <RowDefinition Height="*" /> <RowDefinition Height="*" /> </Grid.RowDefinitions> <Grid.ColumnDefinitions> <ColumnDefinition Width="*" /> <ColumnDefinition Width="*" /> <ColumnDefinition Width="*" /> </Grid.ColumnDefinitions> <MediaElement x:Name="element1" UnloadedBehavior="Close" LoadedBehavior="Manual" Grid.Column="0" Grid.Row="0" /> <MediaElement x:Name="element2" UnloadedBehavior="Close" LoadedBehavior="Manual" Grid.Column="1" Grid.Row="0" /> <MediaElement x:Name="element3" UnloadedBehavior="Close" LoadedBehavior="Manual" Grid.Column="2" Grid.Row="0" /> <MediaElement x:Name="element4" UnloadedBehavior="Close" LoadedBehavior="Manual" Grid.Column="0" Grid.Row="1" /> <MediaElement x:Name="element5" UnloadedBehavior="Close" LoadedBehavior="Manual" Grid.Column="1" Grid.Row="1" /> <MediaElement x:Name="element6" UnloadedBehavior="Close" LoadedBehavior="Manual" Grid.Column="2" Grid.Row="1" /> Here is the sample code: // The code below repeats for each MediaElement List<string> playlist1 = new List<string>() { @"file1.wmv", @"file2.wmv", @"file3.wmv", @"file4.wmv" }; DispatcherTimer timer1 = null; int index1 = 0; ... void Window1_Loaded(object sender, RoutedEventArgs e) { timer1 = new DispatcherTimer(); timer1.Tick += new EventHandler(timer1_Elapsed); timer1.Interval = TimeSpan.FromSeconds(10); element1.Source = new Uri(playlist1[index1]); timer1.Start(); element1.Play(); ... } void timer1_Elapsed(object sender, EventArgs e) { Dispatcher.BeginInvoke(DispatcherPriority.Normal, (System.Threading.ThreadStart)delegate() { element1.Stop(); element1.Close(); timer1.Stop(); index1++; if (index1 >= playlist1.Count) { index1 = 0; } element1.Source = new Uri(playlist1[index1]); timer1.Start(); element1.Play(); }); } ... Does anybody have similar problems?

  • How to construct a flowchart/storyboard in a Func Spec

    - by PeterQ
    Hey I'm a bit embarrassed to write a post on this topic, but I would appreciate the help. At my school, the CS kids (myself included) have created a nice, little program that is built for incoming Chem/Bio students. It consists of several modules that reviews topics they should have a firm grasp on before they start their classes. It's a nice tool since it cuts down on reviewing the material in class but also allows the students to do a quick diagnostic to fix any problems. Now, I'm in charge of constructing a simple interface that reports on the progress of the group and individual students. The interface is pretty simple. It's just a window that pops up, and it has three tabs: the first tab is a "cumulative" report of all of students. The secnod tab has a drop down box that lists the students and once a student is selected, a report for him/her comes up. And the third tab is simply a description of all of the terms used in the 1st and 2nd tabs. Now, I'm trying to be a good CS student and write a func. spec for my interface. My problem comes with the fact that I'd like to insert a little flowchart using Visio. Problem is, and I'm quite embarrassed to admit this, I don't know how to construct the flowchart/storyboard. For instance, I know I start with a "Start/Click Icon" in a rectangle. Then where do I go? Do I draw three arrrows (one going to each tab) and then describing what goes on? In tab one, the only thing that happens is that the user will select a "sort" method in the drop down box. This will sort the list. The End. Similarly, if the user selects the second tab, then he will go to a drop down box with the student names. Selecting a name will bring up student info. And the third tab is just a list of unfamiliar terms coming from the first or second tab. I wanted to storyboard/flowchart what I'm doing, but I'm unclear how to go about it. Any help would be appreciated! (Just to clarify, I'm not having trouble with using Visio, but I don't know how one goes about construct a storyboard or determining the procedure for constructing one)

  • Visitor pattern and compiler code generation, how to get children attributes?

    - by LeleDumbo
    I'd like to modify my compiler's code generator to use visitor pattern since the current approach must use multiple conditional statement to check the real type of a child before generating the corresponding code. However, I have problems to get children attributes after they're visited. For instance, in binary expression I use this: LHSCode := GenerateExpressionCode(LHSNode); RHSCode := GenerateExpressionCode(RHSNode); CreateBinaryExpression(Self,LHS,RHS); In visitor pattern the visit method is usually void, so I can't get the expression code from LHS and RHS. Keeping shared global variables isn't an option since expression code generation is recursive thus could erase previous values kept in the variables. I'll just show the binary expression as this is the most complicated part (for now): function TLLVMCodeGenerator.GenerateExpressionCode( Expr: TASTExpression): TLLVMValue; var BinExpr: TASTBinaryExpression; UnExpr: TASTUnaryExpression; LHSCode, RHSCode, ExprCode: TLLVMValue; VarExpr: TASTVariableExpression; begin if Expr is TASTBinaryExpression then begin BinExpr := Expr as TASTBinaryExpression; LHSCode := GenerateExpressionCode(BinExpr.LHS); RHSCode := GenerateExpressionCode(BinExpr.RHS); case BinExpr.Op of '<': Result := FBuilder.CreateICmp(ccSLT, LHSCode, RHSCode); '<=': Result := FBuilder.CreateICmp(ccSLE, LHSCode, RHSCode); '>': Result := FBuilder.CreateICmp(ccSGT, LHSCode, RHSCode); '>=': Result := FBuilder.CreateICmp(ccSGE, LHSCode, RHSCode); '==': Result := FBuilder.CreateICmp(ccEQ, LHSCode, RHSCode); '<>': Result := FBuilder.CreateICmp(ccNE, LHSCode, RHSCode); '/\': Result := FBuilder.CreateAnd(LHSCode, RHSCode); '\/': Result := FBuilder.CreateOr(LHSCode, RHSCode); '+': Result := FBuilder.CreateAdd(LHSCode, RHSCode); '-': Result := FBuilder.CreateSub(LHSCode, RHSCode); '*': Result := FBuilder.CreateMul(LHSCode, RHSCode); '/': Result := FBuilder.CreateSDiv(LHSCode, RHSCode); end; end else if Expr is TASTPrimaryExpression then if Expr is TASTBooleanConstant then with Expr as TASTBooleanConstant do Result := FBuilder.CreateConstant(Ord(Value), ltI1) else if Expr is TASTIntegerConstant then with Expr as TASTIntegerConstant do Result := FBuilder.CreateConstant(Value, ltI32) else if Expr is TASTUnaryExpression then begin UnExpr := Expr as TASTUnaryExpression; ExprCode := GenerateExpressionCode(UnExpr.Expr); case UnExpr.Op of '~': Result := FBuilder.CreateXor( FBuilder.CreateConstant(1, ltI1), ExprCode); '-': Result := FBuilder.CreateSub( FBuilder.CreateConstant(0, ltI32), ExprCode); end; end else if Expr is TASTVariableExpression then begin VarExpr := Expr as TASTVariableExpression; with VarExpr.VarDecl do Result := FBuilder.CreateVar(Ident, BaseTypeLLVMTypeMap[BaseType]); end; end; Hope you understand it :)

  • Jruby Gems-in-a-jar issue

    - by antonio
    Hi all, I am trying to write some code in ruby (using jruby) to be compiled to java bytecode with jrubyc and deployed to a remote machine where it will be run on the JVM (no ruby available there). Everything works fine as long as I am happy to stick with the standard jruby library. As explained on the jruby website, I simply copy the jruby-complete.jar library to the remote machine and include it in the classpath at runtime. I fire my compiled script and it works: cool! The problems start when I need some other libraries (typically rubygems) to run my script. I am aware of cool stuff like rawr, -which I successfully tested- to put together all you need in a single package. However that is not the solution I am looking for: I will have many small scripts to run independently and I don't want each of them to grow to at least 10 MB just because I insanely include the jruby-complete.jar in each of them. What I would like is to compile a .jar for each of the libraries that I will need to use, put all of them in a common folder on the remote machine and include them at runtime in the classpath when I run my compiled jruby scripts on the JVM. This said, I tried to follow the instructions here: http://blog.nicksieger.com/articles/2009/01/10/jruby-1-1-6-gems-in-a-jar I tried exactly the example shown there, with the "chronic" gem. Going step by step: Install the gem locally: java -jar jruby-complete-1.1.6.jar -S gem install -i ./chronic chronic --no-rdoc --no-ri Package it into a jar: jar cf chronic.jar -C chronic . Write a two lines test script, saving it as testt.rb: require 'chronic' Chronic.parse('tomorrow') Compile with: jrubyc testt.rb Run the resulting java class testt.class with the following (having both jruby-complete.jar and chronic.jar in the same folder as the java class): java -cp .:/jruby-complete.jar:./chronic.jar testt I get the following error: Exception in thread "main" file:/Users/ave2/NetBeansProjects/jrubywatir/lib/jruby-complete.jar!/METAINF/jruby.home/lib/ruby/site_ruby/shared/builtin/core_ext/symbol.rb:1:in `const_missing': uninitialized constant Chronic (NameError) from testt.rb:2 ...internal jruby stack elided... from Module.const_missing(testt.rb:2) from (unknown).(unknown)(:1) I really don't understand what I am doing wrong, and I am totally stuck on this. I am a noob in Ruby, much more used to Python: don't miss a chance to convert an infidel! :-) Thanks.

  • ASP.Net Web Farm Monitoring

    - by cisellis
    I am looking for suggestions on doing some simple monitoring of an ASP.Net web farm as close to real-time as possible. The objectives of this question are to: Identify the best way to monitor several Windows Server production boxes during short (minutes long) period of ridiculous load Receive near-real-time feedback on a few key metrics about each box. These are simple metrics available via WMI such as CPU, Memory and Disk Paging. I am defining my time constraints as soon as possible with 120 seconds delayed being the absolute upper limit. Monitor whether any given box is up (with "up" being defined as responding web requests in a reasonable amount of time) Here are more details, things I've tried, etc. I am not interested in logging. We have logging solutions in place. I have looked at solutions such as ELMAH which don't provide much in the way of hardware monitoring and are not visible across an entire web farm. ASP.Net Health Monitoring is too broad, focuses too much on logging and is not acceptable for deep analysis. We are on Amazon Web Services and we have looked into CloudWatch. It looks great but messages in the forum indicate that the metrics are often a few minutes behind, with one thread citing 2 minutes as the absolute soonest you could expect to receive the feedback. This would be good to have for later analysis but does not help us real-time Stuff like JetBrains profiler is good for testing but again, not helpful during real-time monitoring. The closest out-of-box solution I've seen is Nagios which is free and appears to measure key indicators on any kind of box, including Windows. However, it appears to require a Linux box to run itself on and a good deal of manual configuration. I'd prefer to not spend my time mining config files and then be up a creek when it fails in production since Linux is not my main (or even secondary) environment. Are there any out-of-box solutions that I am missing? Obviously a windows-based solution that is easy to setup is ideal. I don't require many bells and whistles. In the absence of an out-of-box solution, it seems easy for me to write something simple to handle what I need. I've been thinking a simple client-server setup where the server requests a few WMI metrics from each client over http and sticks them in a database. We could then monitor the metrics via a query or a dashboard or something. If the client doesn't respond, it's effectively down. Any problems with this, best practices, or other ideas? Thanks for any help/feedback.

  • Streaming Video with Blackberry Simulator

    - by Jenny
    So, I wrote a quick little app for the iphone that takes in an http URL, and plays the .mp4 video located at that URL (it does more than that, of course, but that's the meat of it). Naturally, I wanted to have it on more than just a single mobile platform, so I decided to target Blackberry next. However, I'm running into a lot of problems with the Blackberry Environment. First of all, I learn that I can only download 256k files! I learn how to set that variable in my MDS simulator (and learn that this is NOT a production solution, because any end users will have to have their BES or MDS admin change the setting there). Then, I find a video less than 2 MB I can practice with. Going to the browser prompts me to save the video (rather than it playing in the browser like I expected). After saving the video, it refuses to play, saying it's the wrong format. So. I can't find a reference to IF Blackberry can stream with HTTP (i"ve heard it CAN use RTSP, though, and heard some rumors that it can't use HTTP, which would really suck). I also can't find a reference to what format blackberry uses (although I can find a million programs that will convert one file to the 'blackberry' format). Surely SOMEONE must have tried to stream video with the blackberry before. How did they go about doing so? Is it just a hopeless pipedream? Will I have to go with RTSP? Sorry for the lack of a concrete question...I'm just really lost, and I hate how so many tutorials or forum posts seem to assume I know the capabilities of the Blackberry... Edit: I finally found out that the .3gp (which I'd never heard of ) format is what Blackberry uses. Still have no idea how to stream videos off the web, though. I found a tutorial: http://www.blackberry.com/knowledgecenterpublic/livelink.exe/fetch/2000/348583/800332/1089414/How%5FTo%5F-%5FPlay%5Fvideo%5Fwithin%5Fa%5FBlackBerry%5Fsmartphone%5Fapplication.html?nodeid=1383173&vernum=0 That seemed to be useful, but the code doesn't work if you give it a URL (even though it claims it does).

  • Using sem_t in a Qt Project

    - by thauburger
    Hi everyone, I'm working on a simulation in Qt (C++), and would like to make use of a Semaphore wrapper class I made for the sem_t type. Although I am including semaphore.h in my wrapper class, running qmake provides the following error: 'sem_t does not name a type' I believe this is a library/linking error, since I can compile the class without problems from the command line. I've read that you can specify external libraries to include during compilation. However, I'm a) not sure how to do this in the project file, and b) not sure which library to include in order to access semaphore.h. Any help would be greatly appreciated. Thanks, Tom Here's the wrapper class for reference: Semaphore.h #ifndef SEMAPHORE_H #define SEMAPHORE_H #include <semaphore.h> class Semaphore { public: Semaphore(int initialValue = 1); int getValue(); void wait(); void post(); private: sem_t mSemaphore; }; #endif Semaphore.cpp #include "Semaphore.h" Semaphore::Semaphore(int initialValue) { sem_init(&mSemaphore, 0, initialValue); } int Semaphore::getValue() { int value; sem_getvalue(&mSemaphore, &value); return value; } void Semaphore::wait() { sem_wait(&mSemaphore); } void Semaphore::post() { sem_post(&mSemaphore); } And, the QT Project File: TARGET = RestaurantSimulation TEMPLATE = app QT += SOURCES += main.cpp \ RestaurantGUI.cpp \ RestaurantSetup.cpp \ WidgetManager.cpp \ RestaurantView.cpp \ Table.cpp \ GUIFood.cpp \ GUIItem.cpp \ GUICustomer.cpp \ GUIWaiter.cpp \ Semaphore.cpp HEADERS += RestaurantGUI.h \ RestaurantSetup.h \ WidgetManager.h \ RestaurantView.h \ Table.h \ GUIFood.h \ GUIItem.h \ GUICustomer.h \ GUIWaiter.h \ Semaphore.h FORMS += RestaurantSetup.ui LIBS += Full Compiler Output: g++ -c -pipe -g -gdwarf-2 -arch i386 -Wall -W -DQT_GUI_LIB -DQT_CORE_LIB -DQT_SHARED - I/usr/local/Qt4.6/mkspecs/macx-g++ -I. - I/Library/Frameworks/QtCore.framework/Versions/4/Headers -I/usr/include/QtCore - I/Library/Frameworks/QtGui.framework/Versions/4/Headers -I/usr/include/QtGui - I/usr/include -I. -I. -F/Library/Frameworks -o main.o main.cpp In file included from RestaurantGUI.h:10, from main.cpp:2: Semaphore.h:14: error: 'sem_t' does not name a type make: *** [main.o] Error 1 make: Leaving directory `/Users/thauburger/Desktop/RestaurantSimulation' Exited with code 2.

  • Running a Java daemon with a GWT front-end served by embedded Jetty

    - by BinaryMuse
    Greetings, coders, Background Info and Code I am trying to create a daemon-type program (e.g., it runs constantly, polling for things to do) that is managed by a GWT application (servlets in a WAR) which is in turn served by an embedded Jetty server (using a WebAppContext). I'm having problems making the GWT application aware of the daemon object. For testing things, I currently have two projects: The daemon and embedded Jetty server in one (EmbJetTest), and the GWT application in another (DefaultApp). This is the current state of the code: First, EmbJetTest creates an embedded Jetty server like so, using a ServletContextListener to inject the daemon object into the web application context: EmbJetTest.server = new Server(8080); // Create and start the daemon Daemon daemon = new Daemon(); Thread thread = new Thread(daemon); thread.start(); // war handler WebAppContext waContext = new WebAppContext(); waContext.setContextPath("/webapp"); waContext.setWar("./apps/DefaultApp.war"); waContext.addEventListener(new DaemonLoader(daemon)); // Add it to the server EmbJetTest.server.setHandler(waContext); EmbJetTest.server.setThreadPool(new QueuedThreadPool(10)); // Start the server; join() blocks until we shut down EmbJetTest.server.start(); EmbJetTest.server.join(); // Stop the daemon thread daemon.stopLoop(); Daemon is a very simple object with a couple properties, at the moment. DaemonLoader is the following ServletContextListener implementation: private Daemon daemon; public DaemonLoader(Daemon daemon) { this.daemon = daemon; } @Override public void contextDestroyed(ServletContextEvent arg0) { } @Override public void contextInitialized(ServletContextEvent arg0) { arg0.getServletContext().setAttribute("daemon", this.daemon); } Then, in one of my servlets in the GWT application, I have the following code: Daemon daemon = (Daemon) this.getServletContext().getAttribute("daemon"); However, when I visit localhost:8080/webapp/* and invoke the servlet, this code throws a ClassCastException, even though the classes are of the same type. This StackOverflow answer indicates that this is because the two classes are loaded with different classloaders. Question My question is twofold. Am I even on the right track here? Am I going about this completely the wrong way? Something tells me I am, but I can't think of another way to make the daemon available to both applications. Is there a better way to communicate with the daemon from the GWT application? Should the GWT app own the daemon and somehow start the daemon itself? The daemon needs to run even if no one visits the one of the GWT app's servlets--how could I do this? If I am on the right track, how can I get around the classloader issue? Thanks in advance.

  • Filter chain halted as [:login_required] rendered_or_redirected

    - by Magicked
    Hopefully I can explain this well enough, but please let me know if more information is needed! I'm building a form where a user can create an "incident". This incident has the following relationships: belongs_to: customer (customer has_many incidents) belongs_to: user (user has_many incidents) has_one: incident_status (incident_status belongs to incident) The form allows the user to assign the incident to a user (select form) and then select an incident status. The incident is nested in customer. However, I'm getting the following in the server logs: Processing IncidentsController#create (for 127.0.0.1 at 2010-04-26 10:41:33) [POST] Parameters: {"commit"=>"Create", "action"=>"create", "authenticity_token"=>"YhW++vd/dnLoNV/DSl1DULcaWq/RwP7jvLOVx9jQblA=", "customer_id"=>"4", "controller"=>"incidents", "incident"=>{"title"=>"Some Bad Incident", "incident_status_id"=>"1", "user_id"=>"2", "other_name"=>"SS01-042310-001"}} User Load (0.3ms) SELECT * FROM "users" WHERE ("users"."id" = 2) LIMIT 1 Redirected to http://localhost:3000/session/new Filter chain halted as [:login_required] rendered_or_redirected. Completed in 55ms (DB: 0) | 302 Found [http://localhost/customers/4/incidents] It looks to me like it's trying to gather information about the user, even though it already has the id (which is all it needs to create the incident), and the user may not have permission to do a select statement like that? I'm rather confused. Here is the relevant (I think) information in the Incident controller. before_filter :login_required, :get_customer def new @incident = @customer.incidents.build @users = @customer.users @statuses = IncidentStatus.find(:all) respond_to do |format| format.html # new.html.erb format.xml { render :xml => @incident } end end def create @incident = @customer.incidents.build(params[:incident]) respond_to do |format| if @incident.save flash[:notice] = 'Incident was successfully created.' format.html { redirect_to(@incident) } format.xml { render :xml => @incident, :status => :created, :location => @incident } else format.html { render :action => "new" } format.xml { render :xml => @incident.errors, :status => :unprocessable_entity } end end end Just as an FYI, I am using the restful_authentication plugin. So in summary, when I submit the incident creation form, it does not save the incident because it halts. I'm still very new to rails, so my skill at diagnosing problems like this is still very bad. I'm going in circles. :) Thanks in advance for any help. Please let me know if more information is needed and I'll edit it in!

  • Nested Sortable JQuery list doesn't work in IE while it does in FF

    - by Ben Fransen
    Hello everybody, While I'm using this site quite often as a resource for jQuery related problems I can't seem to find an answer this time. So here is my first post. During daytime at work I'm developing an informationsystem for generating MS Word documents. One of the modules I'm developing is for defining a default chapterselection for the table of contents and selecting texts by the given chapters. A user can submit new chapters and if necessary, add them as childchapter to a parent, flag them as 'adopt in TOC' and link a default text (from another module) to the chapter. My chapterlist is retreived recursively from a MySQL table and could look something like this: <ul class="sortableChapterlist"> <li>1</li> <li>2 <ul class="sortableChapterlist"> <li>2.1</li> <li>2.2</li> <li>2.3 <ul class="sortableChapterlist"> <li>2.3.1</li> <li>2.3.2</li> </ul> </li> </ul> </li> </ul> In FireFox the code works like a charm but IE (7) doesn't seem to like it that much. I'm only able to correctly drag arround the mainchapters. When attempting to drag a subchapter, no matter it's level, the correspondending mainchapter lifts up with some child, never all. This is the jQuery code I'm using to accomplish the task: $(function(){ $(".sortableChapterlist").sortable({ opacity: 0.7, helper: 'clone', cursor: 'move' }); $(".sortableChapterlist").selectable(); $(".sortableChapterlist").disableSelection(); }); Does anybody have some ideas about this? I'm guessing IE kinda falls over the multiple class reference "chapter_list" in combination with jQuery trying to handle the draggable/sortable. Kinds regards from Holland, Ben Fransen

  • Can't interact with children of an itemRenderer in Flex 4 Gumbo

    - by BlueDude
    I thought this would be pretty easy but I'm running into all sorts of problems with this. I have an ItemRenderer with a an image and two labels. I want to assign separate mouse events to the image and two labels. It seems like the item renderer is treated like a single interactive piece and I haven't found a way to override that.

  • VBA - Access 03 - Iterating through a list box, with an if statement to evaluate

    - by Justin
    So I have a one list box with values like DeptA, DeptB, DeptC & DeptD. I have a method that causes these to automatically populate in this list box if they are applicable. So in other words, if they populate in this list box, I want the resulting logic to say they are "Yes" in a boolean field in the table. So to accomplish this I am trying to use this example of iteration to cycle through the list box first of all, and it works great: dim i as integer dim myval as string For i = o to me.lstResults.listcount - 1 myVal = lstResults.itemdata(i) Next i if i debug.print myval, i get the list of data items that i want from the list box. so now i am trying to evaluate that list so that I can have an UPDATE SQL statement to update the table as i need it to be done. so, i know this is a mistake, but this is what i tried to do (giving it as an example so that you can see what i am trying to get to here) dim sql as string dim i as integer dim myval as string dim db as database sql = "UPDATE tblMain SET " for i = 0 to me.lstResults.listcount - 1 myval = lstResults.itemdata(i) If MyVal = "DeptA" Then sql = sql & "DeptA = Yes" ElseIF myval = "DeptB" Then sql = sql & "DeptB = Yes" ElseIf MyVal = "DeptC" Then sql = sql & "DeptC = Yes" ElseIf MyVal = "DeptD" Then sql = sql & "DeptD = Yes" End If Next i debug.print (sql) sql = sql & ";" set db= currentdb db.execute(sql) msgbox "Good Luck!" So you can see why this is going to cause problems because the listbox that these values (DeptA, DeptB, etc) automatically populate in are dynamic....there is rarely one value in the listbox, and the list of values changes per OrderID (what the form I am using this on populates information for in the first place; unique instance). I am looking for something that will evaluate this list one at a time (i.e. iterate through the list of values, and look for "DeptA", and if it is found add yes to the SQL string, and if it not add no to the SQL string, then march on to the next iteration). Even though the listbox populates values dynamically, they are set values, meaning i know what could end up in it. Thanks for any help, Justin

  • Delphi native Web Service applications not working. IIS 7 seems to be stripping the pathinfo

    - by Cary Jensen
    I've run into an interesting problem that I never encountered with XP or IIS 6. Basically, I can't get a native Delphi (WebBroker) Web service server to work with a native Web service client in Windows 7 64-bit. Here's the most basic breakdown. If I create a new Web service application in Delphi 2010 (or any version, back to Delphi 7), and access it using IE 8, I can see the HTML that the WSDLHTMLPublish component creates, but I can never get to the SOAP. In the same way, the WSDL Importer cannot get to the SOAP either. (I have IIS 7 configured to use a 32-bit application pool, and I have created a working Script Map to the Handler Mappings. In short, the 32-bit ISAPI Web service is running). For example, I have a simple Web service server named TestService (created using the default sample interface generated when you create a new Web service server). I installed it in a virtual directory named scripts. If I enter http://localhost/scripts/TestService.dll/wsdl, IIS 7 displays the page http://localhost/scripts/TestService.dll. If I put my mouse over the WSDL link for the ITestService, I see http://localhost/scripts/TestService.dll/wsdl/ITestService in the status bar. However, when I click this link, the address bar shows http://localhost/scripts/TestService.dll/wsdl/ITestService, but I see only the HTML from http://localhost/scripts/TestService.dll. There seems no way to get to the SOAP definition. IIS 7 seems to be ignoring everything after the script name (it is ignoring the pathinfo). Additional evidence that IIS7 is stripping off the pathinfo is that if I pause my mouse over the ITestService link, the statusbar shows http://localhost/scripts/TestService.dll?intf=ITestService. Clicking that link takes me to another HTML page, the one associated with http://localhost/scripts/TestService.dll?intf=ITestService. However, any link that includes a pathinfo following the script name, takes me simply to http://localhost/scripts/TestService.dll. I have tested this in Delphi 7, Delphi 2010, and Delphi XE, with the same results. I am guessing that IIS7 is stripping off the pathinfo, since even the WSDL Importer cannot get to the SOAP definition. Tried creating a new Web service using the CGI option, and got the same result. Have any idea what is going on? Added: Bob Swart reports he has had no problems under Windows 7 32-bit. Downloading the 32-bit OS and will try that (in a new VM).

  • Using Linq to filter a ComboBox.DataSource ?

    - by Pesche Helfer
    Hi board, in another topic, I've stumbled over this very elegant solution by Darin Dimitrov to filter the DataSource of one ComboBox with the selection of another ComboBox: how to filter combobox in combobox using c# combo2.DataSource = ((IEnumerable<string>)c.DataSource) .Where(x => x == (string)combo1.SelectedValue); I would like to do a similar thing, but intead of filtering by a second combobox, I would like to filter by the text of a TextBox. (Basically, instead of choosing from a second ComboBox, the user simply enters his filter in to a TextBox). However, it turned out to be not as straight forward as I had hoped it would be. I tried stuff as the following, but failed miserably: cbWohndresse.DataSource = ((IEnumerable<DataSet>)ds) .Where(x => x.Tables["Adresse"].Select("AdrLabel LIKE '%TEST%'")); cbWohndresse.DisplayMember = "Adresse.AdrLabel"; cbWohndresse.ValueMember = "Adresse.adress_id"; ds is the DataSet which I would like to use as filtered DataSource. "Adresse" is one DataTable in this DataSet. It contains a DataColumn "AdrLabel". Now I would like to display only those "AdrLabel", which contain the string from the user input. (Currently, %TEST% replaces the textbox.text.) The above code fails because the lambda expression does not return Bool. But I am sure, there are also other problems (which type should I use for IEnumerable? Now it's DataSet, but Darin used String. But how could I convert a DataSet to a string? Yes, I am as much newbyish as it gets, my experience is "void", and publicly so. So please forgive me my rather stupid questions. Your help is greatly appreciated, because I can't solve this on my own (tried hard already). Thank you very much! Pesche P.S. I am only using Linq to achieve an uncomplicated filter for the ComboBox (avoiding a View). The rest is not based on Linq, but on oldstyle Ado.NET (ds is filled by an SqlDataAdapter), if that's of any importance.

  • Using ASP.NET MVC, Linq To SQL, and StructureMap causing DataContext to cache data

    - by Dragn1821
    I'll start by telling my project setup: ASP.NET MVC 1.0 StructureMap 2.6.1 VB I've created a bootstrapper class shown here: Imports StructureMap Imports DCS.Data Imports DCS.Services Public Class BootStrapper Public Shared Sub ConfigureStructureMap() ObjectFactory.Initialize(AddressOf StructureMapRegistry) End Sub Private Shared Sub StructureMapRegistry(ByVal x As IInitializationExpression) x.AddRegistry(New MainRegistry()) x.AddRegistry(New DataRegistry()) x.AddRegistry(New ServiceRegistry()) x.Scan(AddressOf StructureMapScanner) End Sub Private Shared Sub StructureMapScanner(ByVal scanner As StructureMap.Graph.IAssemblyScanner) scanner.Assembly("DCS") scanner.Assembly("DCS.Data") scanner.Assembly("DCS.Services") scanner.WithDefaultConventions() End Sub End Class I've created a controller factory shown here: Imports System.Web.Mvc Imports StructureMap Public Class StructureMapControllerFactory Inherits DefaultControllerFactory Protected Overrides Function GetControllerInstance(ByVal controllerType As System.Type) As System.Web.Mvc.IController Return ObjectFactory.GetInstance(controllerType) End Function End Class I've modified the Global.asax.vb as shown here: ... Sub Application_Start() RegisterRoutes(RouteTable.Routes) 'StructureMap BootStrapper.ConfigureStructureMap() ControllerBuilder.Current.SetControllerFactory(New StructureMapControllerFactory()) End Sub ... I've added a Structure Map registry file to each of my three projects: DCS, DCS.Data, and DCS.Services. Here is the DCS.Data registry: Imports StructureMap.Configuration.DSL Public Class DataRegistry Inherits Registry Public Sub New() 'Data Connections. [For](Of DCSDataContext)() _ .HybridHttpOrThreadLocalScoped _ .Use(New DCSDataContext()) 'Repositories.

I have a form that posts to a details page (/Summary/Details), which loads in some data from SQL. I then have a button that opens a dialog box in JQuery, which populates the dialog from a request to (/Operator/Modify). On the dialog box, the form has a combo box and an OK button that lets the user change the operator's name. Upon clicking OK, the form is posted to (/Operator/Modify) and sent through the service and repository layers of my program and updates the record in the database. Then, the RedirectToAction is called to send the user back to the details page (/Summary/Details) where there is a call to pull the data from SQL again, updating the details view. Everything works great, except the details view does not show the new operator that was selected. I can step through the code and see the DCSDataContext class being accessed to update the operator (which does actually change the database record), but when the DCSDataContext is accessed to reload the details objects, it pulls in the old value. I'm guessing that StructureMap is causing not only the DCSDataContext class but also the data to be cached? I have also tried adding the following to the Global.asax, but it just ends up crashing the program telling me the DCSDataContext has been disposed... Private Sub MvcApplication_EndRequest(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.EndRequest StructureMap.ObjectFactory.ReleaseAndDisposeAllHttpScopedObjects() End Sub Can someone please help?

  • In Protobuf-net how can I pass an array of type object with objects of different types inside, knowi

    - by cloudraven
    I am trying to migrate existing code that uses XmlSerializer to protobuf-net due to the increased performance it offers, however I am having problems with this specific case. I have an object[] that includes parameters that are going to be sent to a remote host (sort of a custom mini rpc facility). I know the set of types from which these parameters can be, but I cannot tell in advance in which order they are going to be sent. I have three constraints. The first is that I am running in Compact Framework, so I need something that works there. Second, as I mentioned performance is a big concern (on the serializing side) so I would rather avoid using a lot of reflection there if possible. And the most important is that I care about the order in which this parameters were sent. Using XmlSerializer it was easy just adding XmlInclude, but for fields there is nothing equivalent as far as I know in Protobuf-net. So, is there a way to do this? Here is a simplified example. [Serializable] [XmlInclude(typeof(MyType1)), XmlInclude(typeof(MyType2)), XmlInclude(typeof(MyType3)) public class Message() { public object[] parameters; public Message(object[] parms) { parameters = parms; } } Message m = new Message(new object[] {MyType1(), 33, "test", new MyType3(), new MyType3()}); MemoryStream ms = new MemoryStream(); XmlSerializer xml = new XmlSerializer(typeof(Message)); xml.Serialize(ms,xml); That will just work with XmlSerializer, but if I try to convert it to protobuf-net I will get a "No default encoding for Object" message. The best I came up with is to use generics and [ProtoInclude] as seen in this example. Since I can have different object types within the array this doesn't quite make it. I added a generic List for each potential type and a property with [ProtoIgnore] with type object[] to add them and get them. I have to use reflection when adding them (to know in which array to put each item) which is not desirable and I still can't preserve the ordering as I just extract all the items on each list one by one and put them into a new object[] array on the property get. I wonder if there is a way to accomplish this?

  • Time complexity of a sorting algorithm

    - by Passonate Learner
    The two programs below get n integers from file and calculates the sum of ath to bth integers q(number of question) times. I think the upper program has worse time complexity than the lower, but I'm having problems calculating the time complexity of these two algorithms. [input sample] 5 3 5 4 3 2 1 2 3 3 4 2 4 [output sample] 7 5 9 Program 1: #include <stdio.h> FILE *in=fopen("input.txt","r"); FILE *out=fopen("output.txt","w"); int n,q,a,b,sum; int data[1000]; int main() int i,j; fscanf(in,"%d%d",&n,&q); for(i=1;i<=n;i++) fscanf(in,"%d",&data[i]); for i=0;i<q;i++) { fscanf(in,"%d%d",&a,&b); sum=0; for(j=a;j<=b;j++) sum+=data[j]; fprintf(out,"%d\n",sum); } return 0; } Program 2: #include <stdio.h> FILE *in=fopen("input.txt","r"); FILE *out=fopen("output.txt","w"); int n,q,a,b; int data[1000]; int sum[1000]; int main() { int i,j; fscanf(in,"%d%d",&n,&q); for(i=1;i<=n;i++) fscanf(in,"%d",&data[i]); for(i=1;i<=n;i++) sum[i]=sum[i-1]+data[i]; for(i=0;i<q;i++) { fscanf(in,"%d%d",&a,&b); fprintf(out,"%d\n",sum[b]-sum[a-1]); } return 0; } The programs below gets n integers from 1 to m and sorts them. Again, I cannot calculate the time complexity. [input sample] 5 5 2 1 3 4 5 [output sample] 1 2 3 4 5 Program: #include <stdio.h> FILE *in=fopen("input.txt","r") FILE *out=fopen("output.txt","w") int n,m; int data[1000]; int count[1000]; int main() { int i,j; fscanf(in,"%d%d",&n,&m); for(i=0;i<n;i++) { fscanf(in,"%d",&data[i]); count[data[i]]++ } for(i=1;i<=m;i++) { for(j=0;j<count[i];j++) fprintf(out,"%d ",i); } return 0; } It's ironic(or not) that I cannot calculate the time complexity of my own algorithms, but I have passions to learn, so please programming gurus, help me!

  • Using Apple’s Bonjour service from .NET?

    - by Martín Marconcini
    I have an iPhone app that publishes through Bonjour. The Mac counterpart works, they sync and exchange data. Now I have to port that little Mac app to Windows. I’ve decided to go with .NET (because that’s what I know). The app is not complex, but I’m in the early stages. I need to browse/discover Bonjour services. For this task, I’ve downloaded Mono.Zeroconf and Apple’s latest SDK (which includes a couple of C# Samples). I’m not really pasting code because I’m really copy/pasting the samples. In fact, Mono.Zeroconf has a MZClient.exe that can be used to test “all the API”. My 1st test was -on the same box- open two cmd.exe and launch a MZclient registering a service and on the other, launch it and “discover it”. It doesn’t work. Here’s the server: C:\MZ>MZClient -v -p "_http._tcp 80 mysimpleweb” *** Registering name = 'mysimpleweb', type = '_http._tcp', domain = 'local.' *** Registered name = ‘mysimpleweb’ On the other terminal: c:\MZ>MZClient -v -t "_http._tcp" Creating a ServiceBrowser with the following settings: Interface = 0 (All) Address Protocol = Any Domain = local Registration Type = _http._tcp Resolve Shares = False Hit ^C when you're bored waiting for responses. And that’s it. Nothing happens. I’ve of course tried with different services to no avail. Even played a little bit with that domain thing. Remember this is the same box. I tried on another computer, because this was a VM inside OSX, so I went ahead and tried on a “pure” win XP. Nothing. note: I have Apple Bonjour Service (up and running) and also the Apple SDK (installed later). Given that this didn’t work, I went ahead and decided to try the Apple SDK which has an Interop and a few pre-compiled samples (and its source code). Short story, neither the mDSNBrowser.exe nor the SimpleChat.exe work/see/discover anything. My box is a Win7 under Parallels, but that doesn’t seem to be affecting anything, given that the native XP exhibits the same problems. What am I doing so awfully wrong?

  • Problem adding subviews (UIButtons) to subclass of UIImageView

    - by samfu_1
    I'm adding a custom button/keypad to my application. Thus far, I have a UIImageView subclass that contains an animation that slides it from the bottom of the screen, and then back down when the user no longer needs it. I'm having trouble adding UIButtons to this UIImageView, however. Since this is a subclass of UIView, I'm attempting to add buttons to my view via the initWithFrame: method. (slideDown method is the added animation) in my UIImageView Subclass, I have a UIButton ivar object added: -(id)initWithFrame:(CGRect)frame { if (self = [super initWithFrame: frame]) { UIButton *button = [UIButton buttonWithType: UIButtonTypeRoundedRect]; button.frame = CGRectMake(16.0, 20.0, 50.0, 50.0); [button setTitle: @"Go" forState: UIControlStateNormal]; [button addTarget: self action: @selector(slideDown) forControlEvents: UIControlEventTouchUpInside]; self.button1 = button; [self addSubview: button1]; NSLog(@"Button added"); } return self; } In my view controller, I instantiate my UIIMageView Subclass in the -(void)viewDidLoad: method as follows: -(void)viewDidLoad { //other objects init'ed ButtonPad *customPad = [[ButtonPad alloc] initWithImage: [UIImage imageNamed: @"ButtonPad.png"]]; customPad.frame = CGRectMake(0.0, 480.0, 320.0, 300.0); self.buttonPad = customPad; [self.view addSubview: buttonPad]; [customPad release]; [super viewDidLoad]; } My current app allows the view to slide up and down off of the screen without any problems. However, the button never appears. I have also tried adding the button to my buttonPad object by instantiating & adding it as a subView to the buttonPad in my view controller file. This worked... but it didn't allow the button to function. I am wondering: A.) Is it appropriate to add buttons or any subview for that matter to the UIView initWithFrame: method or should I be adding these subviews as a subview to my buttonPad in the view Controller file? B.) Since I am creating a custom button/keypad, am i following a valid approach by using a normal UIViewController or should I be using something like a modal view Controller? ( I have little knowledge about these.)

  • Project References DLL version hell

    - by Mr Shoubs
    We're having problems getting visual studio to pick up the latest version of a DLL from one of our projects. We have multiple class library projects (e.g. BusinessLogic, ReportData) and a number of web services, each has a reference to a Connectivity DLL we've written (this ref to the connectivity DLL is the problem). We always point references to the DLL in the bin/debug folder, (which is where we always build to for any given project) and all custom DLL references have CopyLocal = True and SpecificVersion = False ReportData has a reference to business logic (which also has a reference to connectivity - I don't see why this should cause a problem, but thought it is worth mentioning) The weird thing is, when you click "Add Reference" and browse to Connectivity/bin/debug - you hover the mouse over the DLL file, the correct (latest) version is shown (version and file version are always incremented together), but when you click ok, a previous version number is pulled though. Even when I look in the current projects debug folder (where copy local would put the DLL after compiling) that shows the latest version number. - NO WHERE does can I find the previous version of the DLL outside of visual studio, but in that project references it has the old version - even though the path is correct. I'm at a loss as to where it might be getting the old versions from. Or even why it wants that one. This is possibly the most frustraighting problem I have ever come across. Does anyone know how to ensure the latest version is pulled through (preferably automatically or on compile). EDIT: Although not exactly the scenario I'm dealing with I was reading this article and somewhere it mentions about CLR ignoring revision numbers. Understandable (even though this hasn't been a problem before - we're on revision 39), so I thought I would update the build number, still didn't work. In a vain attempt I though I would update the minor version number and see if that made any difference. I'm not saying this is the answer as I have to check quite a few things first, but on the face of it, this seems to have solved my problem... Further edit: In other class libraries this seems to have solved the problem, however in a test windows application it still pulls a previous version through :( If I increment the minor version number again, the same problem come back and I am left with the wrong version being pulled though. Further Edit - I created an entirly new project, added a reference and still had the exact same problem. This suggests the problem is restriced to the project I am referencing. Wish I knew why! Anyone had this problem before and know how to get around it? HELP!
