• Howto - Running Redmine on mongrel as a service on windows

  - by Achilles

  I use Redmine on Mongrel as a project manager and I use a batch file (start-redmine.bat) to start the redmine in mongrel. There are 2 issues with my setup: 1. I have a running IIS on the server that occupies the HTTP port (80) 2. The start-redmine.bat must be periodically checked to see if it's stopped after a restart that is caused by windows update service. for the first issue, I have no choice but running mongrel on a port like 3000 and for the second issue I have to create a windows service that runs automatically in the background when the windows starts; and here comes the trouble! There are at least 3 ways to run redmine as a service that I'm aware of; none of them can satisfy a performance view on this subject. you may read about them on http://stackoverflow.com/questions/877943/how-to-configure-a-rails-app-redmine-to-run-as-a-service-on-windows I tried them all. The easiest way to setup such a service is using mongrel_service approach; in 3 lines of command you're done. but the performance is significantly lower than running that batch file... Now, I wanna show you my approach: First suppose we have ruby installed into c:\ruby and we have issued the command gem install mongrel to get the mongrel gem installed into c:\ruby\bin Also, suppose we have installed the Redmine into a folder like c:\redmine; and we have ruby's path (i.e. c:\ruby\bin) in our PATH environment variable. Now Download and install the Windows NT Resource Kit Tools from microsoft website. Open the command-line tool that comes with the Resource Kit (from start menu). Use instsrv to install a dummy service called Redmine using the following command: "[path-to-instsrv.exe]\instsrv" Redmine "[path-to-srvany.exe]\srvany.exe" in my case (which is the default case) it was something like this: "C:\Program Files\Windows Resource Kits\Tools\instsrv" Redmine "C:\Program Files\Windows Resource Kits\Tools\srvany.exe" Now create the batch file. Open a notepad and paste these instructions into it and then save it as "c:\redmine\start-redmine.bat" @echo off cd c:\redmine\ mongrel_rails start -a 0.0.0.0 -p 3000 -e production Now we need to configure that dummy service we had created before. WATCH OUT WHAT YOU'RE DOING FROM HERE ON, OR YOU MAY CORRUPT YOUR WINDOWS. To configure that service, open windows registry editor (Start - Run - regedit) and navigate to this node: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Redmine Right-Click on "Redmine" node and using the context menu, create a new key called Parameters (New - Key) Right-Click on "Parameters" and create a String Value property called Application. Do this again and create another String Value called AppParameters. Now Double-click on "Application" and put cmd.exe into "Value data" section. Then Double-click on "AppParameters" and put /C "C:\redmine\start-redmine.bat" into Value data section. We're done! issue this command to run the redmine on mongrel as a service: net start Redmine

• heroku mongohq and mongoid Mongo::ConnectionFailure

  - by Ole Morten Amundsen

  I have added the mongoHQ addon for mongodb at heroku. It crashes with something like this. connect_to_master': failed to connect to any given host:port (Mongo::ConnectionFailure) The descriptions online (heroku mongohq) are more directed towards mongomapper, as I see it. I'm running ruby 1.9.1 and rails 3-beta with mongoid. My feeling says that there's something with ENV['MONGOHQ_URL'], which it says the MongoHQ addon sets, but I haven't set MONGOHQ_URL anywhere in my app. I guess the problem is in my mongoid.yml ? defaults: &defaults host: localhost development: <<: *defaults database: aliado_development test: <<: *defaults database: aliado_test # set these environment variables on your prod server production: <<: *defaults host: <%= ENV['MONGOID_HOST'] %> port: <%= ENV['MONGOID_PORT'] %> username: <%= ENV['MONGOID_USERNAME'] %> password: <%= ENV['MONGOID_PASSWORD'] %> database: <%= ENV['MONGOID_DATABASE'] %> It works fine locally, but fails at heroku, more stack trace: ==> crashlog.log <== Cannot write to outdated .bundle/environment.rb to update it /disk1/home/slugs/176479_b14df52_b875/mnt/.bundle/gems/gems/rack-1.1.0/lib/rack.rb:14: warning: already initialized constant VERSION /disk1/home/slugs/176479_b14df52_b875/mnt/.bundle/gems/gems/mongo-0.20.1/lib/mongo/connection.rb:435:in `connect_to_master': failed to connect to any given host:port (Mongo::ConnectionFailure) from /disk1/home/slugs/176479_b14df52_b875/mnt/.bundle/gems/gems/mongo-0.20.1/lib/mongo/connection.rb:112:in `initialize' from /disk1/home/slugs/176479_b14df52_b875/mnt/.bundle/gems/gems/mongoid-2.0.0.beta4 /lib/mongoid/railtie.rb:32:in `new' from /disk1/home/slugs/176479_b14df52_b875/mnt/.bundle/gems/gems/mongoid-2.0.0.beta4/lib/mongoid/railtie.rb:32:in `block (2 levels) in <class:Railtie>' from /disk1/home/slugs/176479_b14df52_b875/mnt/.bundle/gems/gems/mongoid-2.0.0.beta4/lib/mongoid.rb:110:in `configure' from /disk1/home/slugs/176479_b14df52_b875/mnt/.bundle/gems/gems/mongoid-2.0.0.beta4/lib/mongoid/railtie.rb:21:in `block in <class:Railtie>' from /disk1/home/slugs/176479_b14df52_b875/mnt/.bundle/gems/gems/railties-3.0.0.beta3/lib/rails/initializable.rb:25:in `instance_exec' .....

• Eventlet or gevent or Stackless + Twisted, Pylons, Django and SQL Alchemy

  - by Khorkrak

  We're using Twisted extensively for apps requiring a great deal of asynchronous io. There are some cases where stuff is cpu bound instead and for that we spawn a pool of processes to do the work and have a system for managing these across multiple servers as well - all done in Twisted. Works great. The problem is that it's hard to bring new team members up to speed. Writing asynchronous code in Twisted requires a near vertical learning curve. It's as if humans just don't think that way naturally. We're considering a mixed approach perhaps. Maybe do the xmlrpc server part and process management in Twisted still but the other stuff in code that at least looks synchronous while not being as such. Then again I like explicit over implicit so hmmm. Anyway onto greenlets - how well does that stuff work? So there's Stackless and as you can see from my Gallentean avatar I'm well aware of the tremendous success in it's use for CCP's flagship EVE Online game first hand. What about Eventlet or gevent? Well for now only Eventlet works with Twisted. However gevent claims to be faster since it's not a pure python implementation it instead uses libevent. It also has fewer idiosyncrasies and defects supposedly. The documentation there is minimal in comparison to Eventlet and it's maintained by 1 guy as far as I can tell. This makes me leery but all great projects start this way so... Then there's PyPy - I haven't even finished reading about that one yet - just saw it in this thread: Drawbacks of Stackless. So confusing - I'm wondering what the heck to do - sounds like Eventlet is probably the best bet but is it really stable enough? Anyone out there have any experience with it? Should we go with Stackless instead as it's been around and is proven technology - just like Twisted is as well - and they do work together nicely. But still I hate having to have a separate version of Python to do this. what to do.... This somewhat obnoxious blog entry hit the nail on the head for me though: Asynchronous IO for Grownups We're stuck using MySQL as well - I never knew how great PostgreSQL was until having had to work on a production OLTP system in MySQL instead - but that's another story. But if that monkey patch thing really works then wow. Just wow.

• sharepoint search is not working

  - by Nikkho

  Hi all, I have an issue with SharePoint search. The situation The server is installed with SharePoint on a farm with 2 servers. A new app pool is created and that app pool is using a domain account called moss_service. moss_service is set to be in the administrator group in both server. moss_service is also set to be the db_creator in the content database. When I checked it initially, the search's default content access account is using another different account, I changed that to be using moss_service account. I didn't do IIS reset because this is a production server, they dont want frequent iis reset. Strangely, checking the services.msc under "office sharepoint server search" the account is still using an old one. (and apparently it's only running on 1 server, the other server is not running) I then change that to the following: domain\moss_service with the password. and then I rerun the crawl. How do I diagnose the issue Basically everytime I change something I restart the crawl and then check the event viewer. Multiple things come out but the following is the major ones: The start address cannot be crawled. The password for the content access account cannot be decrypted because it was stored with different credentials. Re-type the password for the account used to crawl this content. (0x80042406) Performance monitoring cannot be initialized for the gatherer object, because the counters are not loaded or the shared memory object cannot be opened. This only affects availability of the perfmon counters. Restart the computer. Access is denied. Check that the Default Content Access Account has access to this content, or add a crawl rule to crawl this content. (0x80041205) Crawl Logs Result The crawl log is showing this: The password for the content access account cannot be decrypted because it was stored with different credentials. Re-type the password for the account used to crawl this content. I tried changing it again at service.mstsc and the rerun the full crawl again but then it doesn't work. I have tried entering it using the following way: [email protected] and domain\moss_service My Questions are: How do I fix this? Is this the right way to setup the search? Does the search account has to be using a different domain account? Seemed like one fix complicates the other, how do I set this right? Is it worth it to upgrade to sp2?

• How can I do something ~after~ an event has fired in C#?

  - by Siracuse

  I'm using the following project to handle global keyboard and mouse hooking in my C# application. This project is basically a wrapper around the Win API call SetWindowsHookEx using either the WH_MOUSE_LL or WH_KEYBOARD_LL constants. It also manages certain state and generally makes this kind of hooking pretty pain free. I'm using this for a mouse gesture recognition software I'm working on. Basically, I have it setup so it detects when a global hotkey is pressed down (say CTRL), then the user moves the mouse in the shape of a pre-defined gesture and then releases global hotkey. The event for the KeyDown is processed and tells my program to start recording the mouse locations until it receives the KeyUp event. This is working fine and it allows an easy way for users to enter a mouse-gesture mode. Once the KeyUp event fires and it detects the appropriate gesture, it is suppose to send certain keystrokes to the active window that the user has defined for that particular gesture they just drew. I'm using the SendKeys.Send/SendWait methods to send output to the current window. My problem is this: When the user releases their global hotkey (say CTRL), it fires the KeyUp event. My program takes its recorded mouse points and detects the relevant gesture and attempts to send the correct input via SendKeys. However, because all of this is in the KeyUp event, that global hotkey hasn't finished being processed. So, for example if I defined a gesture to send the key "A" when it is detected, and my global hotkey is CTRL, when it is detected SendKeys will send "A" but while CTRL is still "down". So, instead of just sending A, I'm getting CTRL-A. So, in this example, instead of physically sending the single character "A" it is selecting-all via the CTRL-A shortcut. Even though the user has released the CTRL (global hotkey), it is still being considered down by the system. Once my KeyUp event fires, how can I have my program wait some period of time or for some event so I can be sure that the global hotkey is truly no longer being registered by the system, and only then sending the correct input via SendKeys?

• Reading a POP3 server with only TcpClient and StreamWriter/StreamReader[SOLVED]

  - by WebDevHobo

  I'm trying to read mails from my live.com account, via the POP3 protocol. I've found the the server is pop3.live.com and the port if 995. I'm not planning on using a pre-made library, I'm using NetworkStream and StreamReader/StreamWriter for the job. I need to figure this out. So, any of the answers given here: http://stackoverflow.com/questions/44383/reading-email-using-pop3-in-c are not usefull. It's part of a larger program, but I made a small test to see if it works. Eitherway, i'm not getting anything. Here's the code I'm using, which I think should be correct. EDIT: this code is old, please refer to the second block problem solved. public Program() { string temp = ""; using(TcpClient tc = new TcpClient(new IPEndPoint(IPAddress.Parse("127.0.0.1"),8000))) { tc.Connect("pop3.live.com",995); using(NetworkStream nws = tc.GetStream()) { using(StreamReader sr = new StreamReader(nws)) { using(StreamWriter sw = new StreamWriter(nws)) { sw.WriteLine("USER " + user); sw.Flush(); sw.WriteLine("PASS " + pass); sw.Flush(); sw.WriteLine("LIST"); sw.Flush(); while(temp != ".") { temp += sr.ReadLine(); } } } } } Console.WriteLine(temp); } Visual Studio debugger constantly falls over tc.Connect("pop3.live.com",995); Which throws an "A socket operation was attempted to an unreachable network 65.55.172.253:995" error. So, I'm sending from port 8000 on my machine to port 995, the hotmail pop3 port. And I'm getting nothing, and I'm out of ideas. Second block: Problem was apparently that I didn't write the quit command. The Code: public Program() { string str = string.Empty; string strTemp = string.Empty; using(TcpClient tc = new TcpClient()) { tc.Connect("pop3.live.com",995); using(SslStream sl = new SslStream(tc.GetStream())) { sl.AuthenticateAsClient("pop3.live.com"); using(StreamReader sr = new StreamReader(sl)) { using(StreamWriter sw = new StreamWriter(sl)) { sw.WriteLine("USER " + user); sw.Flush(); sw.WriteLine("PASS " + pass); sw.Flush(); sw.WriteLine("LIST"); sw.Flush(); sw.WriteLine("QUIT "); sw.Flush(); while((strTemp = sr.ReadLine()) != null) { if(strTemp == "." || strTemp.IndexOf("-ERR") != -1) { break; } str += strTemp; } } } } } Console.WriteLine(str); }

• Adding delegate with calendar access using Exchange Web Services?

  - by BryanG

  I have a set up where I need to add a delegate to various user calendars programmatically. Using a sample from MDSN, I've gotten as far as trying to add the delegate, but after the call to the service binding, I get nothing back...no success or fail....nothing. How I create the service binidng: // Initialize the service binding serviceBinding = new ExchangeServiceBinding(); serviceBinding.Credentials = new NetworkCredential(Properties.Settings.Default.UserName, Properties.Settings.Default.Password, Properties.Settings.Default.Domain); // A production application should call the autodiscover service to locate the service binding url serviceBinding.Url = Properties.Settings.Default.EWSUrlEndPoint; serviceBinding.RequestServerVersionValue = new RequestServerVersion(); serviceBinding.RequestServerVersionValue.Version = ExchangeVersionType.Exchange2007_SP1; serviceBinding.AllowAutoRedirect = true; and the delegate addition: static void AddDelegate(string email) { // Create the request. AddDelegateType request = new AddDelegateType(); // Identify the agent's mailbox. request.Mailbox = new EmailAddressType(); request.Mailbox.EmailAddress = email; // add the exch_integration user as a delegate request.DelegateUsers = new DelegateUserType[1]; request.DelegateUsers[0] = new DelegateUserType(); request.DelegateUsers[0].UserId = new UserIdType(); request.DelegateUsers[0].UserId.PrimarySmtpAddress = "[email protected]"; // Specify the permissions that are granted to exch_integration request.DelegateUsers[0].DelegatePermissions = new DelegatePermissionsType(); request.DelegateUsers[0].DelegatePermissions.CalendarFolderPermissionLevel = DelegateFolderPermissionLevelType.Author; request.DelegateUsers[0].DelegatePermissions.CalendarFolderPermissionLevelSpecified = true; // Specify whether the agent recieves meeting requests. request.DeliverMeetingRequests = DeliverMeetingRequestsType.DelegatesAndSendInformationToMe; request.DeliverMeetingRequestsSpecified = true; try { // Send the request and get the response. AddDelegateResponseMessageType response = serviceBinding.AddDelegate(request); DelegateUserResponseMessageType[] responseMessages = response.ResponseMessages; // One DelegateUserResponseMessageType exists for each attempt to add a delegate user to an account. foreach (DelegateUserResponseMessageType user in responseMessages) { Console.WriteLine("Results of adding user: " + user.ResponseClass.ToString()); Console.WriteLine(user.DelegateUser.UserId.DisplayName); Console.WriteLine(user.DelegateUser.UserId.PrimarySmtpAddress); Console.WriteLine(user.DelegateUser.UserId.SID); } Console.ReadLine(); } catch (Exception e) { Console.WriteLine(e.Message); Console.ReadLine(); } } The response nothing which must mean that the AddDelegate call isn't hitting the server properly, but I'm not sure. Thanks.

  I have the following query, now the strange thing is if I run this query on my development and pre-prod server it runs fine. If I run it on production it fails.

• WCF - Multiple schema HTTP and HTTPS in the same service

  - by Ender

  I am trying to set up WCF service in production. The service has two bindings with two different interfaces. One endpoint (basicHttpBinding) is set up at HTTP and the other endpoint (wsHttpBinding) is set up securely over SSL. I can't get this scenario to work. Everything works with no problem if both endpoints are set up over HTTP. Before I even get into the specifics of errors I get, is is possible to run secure and insecure endpoint over the same service ? Here is a brief description of my configuration: <serviceBehaviors> <behavior name="MyServiceBehavior"> <serviceMetadata httpGetEnabled="true" httpsGetEnabled="true" /> <serviceCredentials> <serviceCertificate findValue="123312123123123123123399451b178" storeLocation="LocalMachine" storeName="My" x509FindType="FindByThumbprint" /> <issuedTokenAuthentication allowUntrustedRsaIssuers="true"/> </serviceCredentials> </behavior> </serviceBehaviors> <bindings> <basicHttpBinding> <binding name="basicHttpBinding" maxReceivedMessageSize="2147483647"> </binding> </basicHttpBinding> <wsHttpBinding> <binding name="wsHttpBinding" maxReceivedMessageSize="2147483647"> <security mode="TransportWithMessageCredential"> <message clientCredentialType="UserName" establishSecurityContext="False"/> </security> </binding> </wsHttpBinding> </bindings> <services> <service behaviorConfiguration="MyServiceBehavior" name="MyService"> <endpoint binding="wsHttpBinding" bindingConfiguration="wsHttpBinding" contract="IMyService1"> </endpoint> <endpoint address="mms" binding="basicHttpBinding" bindingConfiguration="basicHttpBinding" contract="IMyService2"> </endpoint> <endpoint address="mex" listenUri="" binding="mexHttpBinding" contract="IMetadataExchange" /> </service> </services> Thanks !

• Sentiment analysis with NLTK python for sentences using sample data or webservice?

  - by Ke

  I am embarking upon a NLP project for sentiment analysis. I have successfully installed NLTK for python (seems like a great piece of software for this). However,I am having trouble understanding how it can be used to accomplish my task. Here is my task: I start with one long piece of data (lets say several hundred tweets on the subject of the UK election from their webservice) I would like to break this up into sentences (or info no longer than 100 or so chars) (I guess i can just do this in python??) Then to search through all the sentences for specific instances within that sentence e.g. "David Cameron" Then I would like to check for positive/negative sentiment in each sentence and count them accordingly NB: I am not really worried too much about accuracy because my data sets are large and also not worried too much about sarcasm. Here are the troubles I am having: All the data sets I can find e.g. the corpus movie review data that comes with NLTK arent in webservice format. It looks like this has had some processing done already. As far as I can see the processing (by stanford) was done with WEKA. Is it not possible for NLTK to do all this on its own? Here all the data sets have already been organised into positive/negative already e.g. polarity dataset http://www.cs.cornell.edu/People/pabo/movie-review-data/ How is this done? (to organise the sentences by sentiment, is it definitely WEKA? or something else?) I am not sure I understand why WEKA and NLTK would be used together. Seems like they do much the same thing. If im processing the data with WEKA first to find sentiment why would I need NLTK? Is it possible to explain why this might be necessary? I have found a few scripts that get somewhat near this task, but all are using the same pre-processed data. Is it not possible to process this data myself to find sentiment in sentences rather than using the data samples given in the link? Any help is much appreciated and will save me much hair! Cheers Ke

• Are PackageMaker installations with preinstall scripts broken on Snow Leopard?

  - by Stu Thompson

  Everything worked on 10.5, but now my PackageMaker installation project is broken. I've been fighting a problem for a few days now, and either Snow Leopard (OS X 10.6.1) has broken PackageMaker installations I am lacking a very, very basic tidbit of knowledge To narrow down the problem, I've gotten to this point: Create a new PackageMaker installation Have it install a jpeg image into my home directoy Define a preinstall script that does nothing #/bin/sh exit 0 Run the above...and watch it fail with the below error message like clock work Sep 14 15:09:45 manoa installd[5620]: PackageKit: ----- Begin install ----- Sep 14 15:09:45 manoa installd[5620]: PackageKit: request=PKInstallRequest <1 packages, destination=/> Sep 14 15:09:45 manoa installd[5620]: PackageKit: packages=(\n "PKLeopardPackage <file://localhost/Users/stu/Desktop/asdf.pkg>"\n) Sep 14 15:09:46 manoa installd[5620]: PackageKit: Extracting /Users/stu/Desktop/asdf.pkg (destination=/var/folders/Hb/HbXJFyEpFaupt5QyLN-pTk+++TI/-Tmp-/PKInstallSandbox-tmp/Root/~, uid=501) Sep 14 15:09:46 manoa installd[5620]: PackageKit: Executing script "./preinstall" in /private/tmp/PKInstallSandbox.cmlS2H/Scripts/test.test.5year_header.pkg.PFrHNB Sep 14 15:09:46 manoa installd[5620]: PackageKit: *** launch path not accessible Sep 14 15:09:46 manoa installd[5620]: PackageKit: Install Failed: PKG: pre-install scripts for "test.test.5year_header.pkg"\nError Domain=PKInstallErrorDomain Code=112 UserInfo=0x100149430 "An error occurred while running scripts from the package “asdf”." {\n NSFilePath = "./preinstall";\n NSLocalizedDescription = "An error occurred while running scripts from the package \U201casdf\U201d.";\n NSURL = "file://localhost/Users/stu/Desktop/asdf.pkg";\n PKInstallPackageIdentifier = "test.test.5year_header.pkg";\n} Sep 14 15:09:46 manoa Installer[5614]: install:didFailWithError:Error Domain=PKInstallErrorDomain Code=112 UserInfo=0x1195917c0 "An error occurred while running scripts from the package “asdf”."

There is no file in /private/tmp/PKInstallSandbox.cmlS2H/Scripts/test.test.5year_header.pkg.PFrHNB/, which makes me think the problem is with PackageMaker, and not me. But I'm new to the world of OS X software installation, so doubts remain. So, the question: Is PackageMaker with a preinstall script broken on OS X 10.6? Or is there some requirement regarding preinstall scripts that I do not understand?

• mysql never releases memory

  - by Ishu

  I have a production server clocking about 4 million page views per month. The server has got 8GB of RAM and mysql acts as a database. I am facing problems in handling mysql to take this load. I need to restart mysql twice a day to handle this thing. The problem with mysql is that it starts with some particular occupation, the memory consumed by mysql keeps on increasing untill it reaches the maximum it can consume and then mysql stops responding slowly or does not respond at all, which freezes the server. All my tables are indexed properly and there are no long queries. I need some one to help on how to go about debugging what to do here. All my tables are myisam. I have tried configuring the parameters key_buffer etc but to no rescue. Any sort of help is greatly appreciated. Here are some parameters which may help. mysql --version mysql Ver 14.12 Distrib 5.0.77, for redhat-linux-gnu (i686) using readline 5.1 mysql> show variables;

• Browser connects to WCF service but not my WCF client. What can be the reason?

  - by Slauma

  On a production server (Windows Server 2003 SP2) I can connect to a remote WCF service with Internet Explorer 8: When I browse to the URL http://www.domain.com/Service.svc (where my service listens) I get the expected info page of the service displayed. Connection settings in Internet Explorer only specify "auto detect", proxy settings are disabled. If I start a console application (built with WCF in .NET 4.0) on the same server which also tries to connect to the same WCF service it fails telling me that no endpoint was available listening on http://www.domain.com/Service.svc. Configuration of the WCF client: <configuration> <system.serviceModel> <bindings> <wsHttpBinding> <binding name="WSHttpBinding_IMyService" closeTimeout="00:01:00" openTimeout="00:01:00" receiveTimeout="00:10:00" sendTimeout="00:01:00" bypassProxyOnLocal="false" transactionFlow="false" hostNameComparisonMode="StrongWildcard" maxBufferPoolSize="524288" maxReceivedMessageSize="65536" messageEncoding="Text" textEncoding="utf-8" useDefaultWebProxy="true" allowCookies="false"> <readerQuotas maxDepth="32" maxStringContentLength="8192" maxArrayLength="16384" maxBytesPerRead="4096" maxNameTableCharCount="16384" /> <reliableSession ordered="true" inactivityTimeout="00:10:00" enabled="false" /> <security mode="None"> <transport clientCredentialType="Windows" proxyCredentialType="None" realm="" /> <message clientCredentialType="Windows" negotiateServiceCredential="true"/> </security> </binding> </wsHttpBinding> </bindings> <client> <endpoint address="http://www.domain.com/Service.scv" binding="wsHttpBinding" bindingConfiguration="WSHttpBinding_IMyService" contract="Service.IMyService" name="WSHttpBinding_IMyService" /> </client> </system.serviceModel> <configuration> With these settings I can communicate successfully with the remote service from my development machine. Looking around for other options I found that I can specify to use the Internet Explorer proxy settings with: <system.net> <defaultProxy> <proxy usesystemdefault="true" /> </defaultProxy> </system.net> It didn't work and I am not sure if I understood this setting really correctly. (My hope was that the WCF client will adopt the "autodetect" setting of Internet Explorer and then connect the same way to the service like the installed IE.) I also had toggled the useDefaultWebProxy setting in the binding configuration between true and false with no success. Now I am asking for help what I can do? Which settings might be wrong or missing? What could I test and how can I get more detailed error messages to better identify the problem? Thank you in advance!

• Problems with office automation in asp.net. I can use alternatives such as open-office, if I knew ho

  - by Vinicius Melquiades

  I have a ASP.NET 2.0 web application that should upload a ppt file and then extract its slides to images. For that I have imported office.dll and Microsoft.Office.Interop.PowerPoint.dll assemblies and wrote the following code public static int ExtractImages(string ppt, string targetPath, int width, int height) { var pptApplication = new ApplicationClass(); var pptPresentation = pptApplication.Presentations.Open(ppt, MsoTriState.msoTrue, MsoTriState.msoFalse, MsoTriState.msoFalse); var slides = new List<string>(); for (var i = 1; i <= pptPresentation.Slides.Count; i++) { var target = string.Format(targetPath, i); pptPresentation.Slides[i].Export(target, "jpg", width, height); slides.Add(new FileInfo(target).Name); } pptPresentation.Close(); return slides.Count; } If I run this code in my local machine, in asp.net or a executable, it runs perfectly. But If I try running it in the production server, I get the following error: System.Runtime.InteropServices.COMException (0x80004005): PowerPoint could not open the file. at Microsoft.Office.Interop.PowerPoint.Presentations.Open(String FileName, MsoTriState ReadOnly, MsoTriState Untitled, MsoTriState WithWindow) at PPTImageExtractor.PptConversor.ExtractImages(String caminhoPpt, String caminhoDestino, Int32 largura, Int32 altura, String caminhoThumbs, Int32 larguraThumb, Int32 alturaThumb, Boolean geraXml) at Upload.ProcessRequest(HttpContext context) The process is running with the user NT AUTHORITY\NETWORK SERVICE. IIS is configured to use anonymous authentication. The anonymous user is an administrator, I set it like this to allow the application to run without having to worry about permissions. In my development machine I have office 2010 beta1. I have tested with the executable in a pc with office 2007 as well. And if I run the code from the executable in the server, with office 2003 installed, it runs perfectly. To ensure that there wouldn't be any problems with permissions, everyone in the server has full access to the web site. The website is running in IIS7 and Classic Mode. I also heard that Open-office has an API that should be able to do this, but I couldn't find anything about it. I don't mind using DLLImport to do what I have to do and I can install open-office on the web server. Don't worry about rewriting this method, as long as the parameters are the same, everything will work. I appreciate your help. ps: Sorry for bad English.

• ASP.NET Web Service Throws 401 (unauthorized) Error

  - by user268611

  Hi Experts, I have this .NET application to be run in an intranet environment. It is configured so that it requires Windows Authentication before you can access the website (Anonymous access is disabled). This website calls a web service (enable anonymous access) and the web service calls the DB. We do have a token-based authentication between the web application and the web service to secure the communication between them. The issue I'm facing is that when I deploy this to production, I'm having an intermittent issue whereby the communication between the web application and the web service failed. The 401 issue was thrown. This is actually working fine in our QA environment. Is this an issue with Active Directory? Or could it be an isssue with FQDN as mentioned here: http://support.microsoft.com/default.aspx?scid=kb;en-us;896861? The weirdest thing is that this is happening intermittently when tested in both on the server itself and a remote workstation in my client's environment.

• WebClient security error when accessing the world of warcraft armoury

  - by user348446

  Hello World, I am trying to piece together a solution to a problem. Basically I am using Silverlight 4 with C# 4.0 to access the world of warcraft armoury. If anyone has done this - please oh please provide the working .net 4.0 code. The code I am attempting to run is (e.Error contains a securtiy error): private void button10_Click(object sender, RoutedEventArgs e) { string url = @"http://eu.wowarmory.com/guild-info.xml?r=Eonar&n=Gifted and Talented"; WebClient wc = new WebClient(); // HOW DO I ADD A USER AGENT STRING (RESPONSE MAY VARY (I.E. HTML VS XML) IF PAGE THINKS CALL IS NOT CAPABABLE OF SUPPORTING XML TRANSFORMATIONS) //wc.ResponseHeaders["User-Agent"] = "Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 6.0)"; wc.DownloadStringCompleted += new DownloadStringCompletedEventHandler(wc_DownloadStringCompleted); wc.DownloadStringAsync(new Uri(url)); } void wc_DownloadStringCompleted(object sender, DownloadStringCompletedEventArgs e) { if (e.Error == null) { string result = e.Result; XDocument ArmouryXML = XDocument.Parse(result); ShowGuildies(ArmouryXML); } else { MessageBox.Show("Something is complaining about security but not sure what!"); } } Notes: C# 4.0 The armoury is an XML file - but i believe it reverts to html should the request not be from a browser that supports XML transformation. But i don't think I am getting this far. The armoury has a cross domain policy file on it - this may be the cause of the error (not sure! I have uploaded to a production server I am testing it locally using IIS website I am going insane! Websites have made the suggestion that this problem can be overcome by creating a WebProxy - but I haven't the first clue how to do this. It would be great if someone could take on this challenge and show us all that it is possible. I'd prefer a non-proxy solution first, then try a proxy. The error details: e.Error = {System.Security.SecurityException --- System.Security.SecurityException: Security error. at System.Net.Browser.BrowserHttpWebRequest.InternalEndGetResponse(IAsyncResult asyncResult) at System.Net.Browser.BrowserHttpWebRequest.<c__DisplayClass5. Any intelligent master coders out there who can solve this in their sleep? Thanks if you can! Pass this on to someone who can if you can't. If you know someone who can't, don't pass it to them, but if you know someone can't then presumedly you know how to solve it and would encourage you to give it a go! Cheers! Dan.

• ASP.NET web forms as ASP.NET MVC

  - by lopkiju

  I am sorry for possible misleading about the title, but I have no idea for a proper title. Feel free to edit. Anyway, I am using ASP.NET Web Forms, and maybe this isn't how web forms is intended to be used, but I like to construct and populate HTML elements manually. It gives me more control. I don't use DataBinding and that kind of stuff. I use SqlConnection, SqlCommand and SqlDataReader, set SQL string etc. and read the data from the DataReader. Old school if you like. :) I do create WebControls so that I don't have to copy-paste every time I need some control, but mostly, I need WebControls to render as HTML so I can append that HTML into some other function that renders the final output with the control inside. I know I can render a control with control.RenderControl(writer), but this can only be done in (pre)Render or RenderContents overrides. For example. I have a dal.cs file where is stored all static functions and voids that communicate with the database. Functions mostly return string so that it can be appended into some other function to render the final result. The reason I am doing like this is that I want to separate the coding from the HTML as much as I can so that I don't do <% while (dataReader.Read()) % in HTML and display the data. I moved this into a CodeBehind. I also use this functions to render in the HttpHandler for AJAX response. That works perfectly, but when I want to add a control (ASP.NET Server control (.cs extension, not .ascx)) I don't know how to do that, so I see my self writing the same control as function that returns string or another function inside that control that returns string and replaces a job that would RenderContents do, so that I can call that function when I need control to be appended into a another string. I know this may not be a very good practice. As I see all the tutorials/videos about the ASP.NET MVC, I think it suite my needs as with the MVC you have to construct everything (or most of it) by your self, which I am already doing right now with web forms. After this long intro, I want to ask how can I build my controls so I can use them as I mentioned (return string) or I have to forget about server controls and build the controls as functions and used them that way? Is that even possible with ASP.NET Server Controls (.cs extension) or am I right when I said that I am not using it right. To be clear, I am talking about how to properly use a web forms, but to avoid data binders because I want to construct everything by my self (render HTML in Code Behind). Someone might think that I am appending strings like "some " + "string", which I am not. I am using StringBuilder for that so there's no slowness. Every opinion is welcome.

• firefox, jQuery ajax calls firing twice and never triggering success or error functions

  - by Adrian Adkison

  Hi, I am developing with the .NET framework, using jQuery 1.4.2 client side. When developing in Firefox version 3.6, every so often an one of the many ajax calls I make on the page will fire twice, the second will return successfully but will not trigger the success handler of the ajax call and the first never returns anything. So basically the data is all sent to the server and response is sent down but nothing happens with the response. Here is an example of the call I am making. It happens to any of the ajax calls, so there is not one particular that is causing the problem: $.ajax({ type:"POST", contentType : "application/json; charset=utf-8", data:"{}", dataType:"json", success:function(){ alert('success'); }, error:function(){ alert('error'); }, url:'/services.aspx/somemethod' }); }) From firebug, here are the headers of the first call which in firebug shows as never completely responding, meaning i see no response code and the loader gif in the firebug never goes away. Note:In firebug it usually says Response Header but for the first call this space is blank Server ASP.NET Development Server/9.0.0.0 X-AspNet-Version 2.0.50727 Content-Type application/json; charset=utf-8 Connection Close Request Headers Host mydomain.com User-Agent Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US; rv:1.9.2.3) Gecko/20100401Firefox/3.6.3 ( .NET CLR 3.5.30729) Accept application/json, text/javascript, */* Accept-Language en-us,en;q=0.5 Accept-Encoding gzip,deflate Accept-Charset ISO-8859-1,utf-8;q=0.7,*;q=0.7 Keep-Alive 115 Connection keep-alive Content-Type application/json; charset=utf-8 X-Requested-With XMLHttpRequest Referer http://mydomain.com/mypage.aspx Here is the header from the second request which just appear to complete in firebug (i.e response is 200): Response Header Server ASP.NET Development Server/9.0.0.0 X-AspNet-Version 2.0.50727 Content-Type application/json; charset=utf-8 Connection Close Request Headers Host mydomain.com User-Agent Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US; rv:1.9.2.3) Gecko/20100401 Firefox/3.6.3 ( .NET CLR 3.5.30729) Accept text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8 Accept-Language en-us,en;q=0.5 Accept-Encoding gzip,deflate Accept-Charset ISO-8859-1,utf-8;q=0.7,*;q=0.7 Keep-Alive 115 Connection keep-alive Content-Type application/json; charset=utf-8 Referer http://mydomain.com/mypage.aspx To summarize my question, why are two requests being made and why are neither of them triggering a success or error handler in the ajax call. I have seen this article about firefox 3.5+ and preflighted requests https://developer.mozilla.org/En/HTTP_access_control#Preflighted_requests In the article is says if a "POST" is made with any other content type than "application/x-www-form-urlencoded, multipart/form-data, or text/plain" than the request is pre-flighted. If this is the case, this should happen to all of my calls. Thanks

• Crawling engine architecture - Java/ Perl integration

  - by Bigtwinz

  Hi all, I am looking to develop a management and administration solution around our webcrawling perl scripts. Basically, right now our scripts are saved in SVN and are manually kicked off by SysAdmin/devs etc. Everytime we need to retrieve data from new sources we have to create a ticket with business instructions and goals. As you can imagine, not an optimal solution. There are 3 consistent themes with this system: the retrieval of data has a "conceptual structure" for lack of a better phrase i.e. the retrieval of information follows a particular path we are only looking for very specific information so we dont have to really worry about extensive crawling for awhile (think thousands-tens of thousands of pages vs millions) crawls are url-based instead of site-based. As I enhance this alpha version to a more production-level beta I am looking to add automation and management of the retrieval of data. Additionally our other systems are Java (which I'm more proficient in) and I'd like to compartmentalize the perl aspects so we dont have to lean heavily on outside help. I've evaluated the usual suspects Nutch, Droid etc but the time spent on modifying those frameworks to suit our specific information retrieval cant be justified. So I'd like your thoughts regarding the following architecture. I want to create a solution which use Java as the interface for managing and execution of the perl scripts use Java for configuration and data access stick with perl for retrieval An example use case would be a data analyst delivers us a requirement for crawling perl developer creates the required script and uses this webapp to submit the script (which gets saved to the filesystem) the script gets kicked off from the webapp with specific parameters .... Webapp should be able to create multiple threads of the perl script to initiate multiple crawlers. So questions are what do you think how solid is integration between Java and Perl specifically from calling perl from java has someone used such a system which actually is part perl repository The goal really is to not have a whole bunch of unorganized perl scripts and put some management and organization on our information retrieval. Also, I know I can use perl do do the web part of what we want - but as I mentioned before - trying to keep perl focused. But it seems assbackwards I'm not adverse to making it an all perl solution. Open to any all suggestions and opinions. Thanks

• Adding OutputCache to a WebForm crashes my site :(

  Hi folks, When I add either ... <%@ OutputCache Duration="600" Location="Any" VaryByParam="*" %> or <%@ OutputCache CacheProfile="CmsArticlesListOrItem" %> (.. and this into the web.config file...) <caching> <outputCacheSettings> <outputCacheProfiles> <add name="CmsArticlesListOrItem" duration="600" varyByParam="*" /> </outputCacheProfiles> </outputCacheSettings> <sqlCacheDependency ........ ></sqlCacheDependency </caching> my page/site crashes with the following error:- Source: System.Web ---------------------------------------------------------------------------- TargetSite: System.Web.DirectoryMonitor FindDirectoryMonitor(System.String, Boolean, Boolean) ---------------------------------------------------------------------------- Message:System.Web.HttpException: Directory 'C:\Web Sites\My Site Foo - Main Site\Controls\InfoAdvice' does not exist.

Well, i've had this site live for around 3 years and i'm pretty sure that the folders \Controls and \Controls\InfoAdvice doesn't exist on my production server. On my localhost, it sure does .. and contains a large list of ascx controls. But they don't exist on my live server. So ... what is going on here? Can anyone please help? Oh :) Before someone suggests I create those two folders and even stick a random file in those folders .. and have some random text in those random files .. i've done that and it doesn't seem to work, still :( Please Help !

• java.lang.Error: "Not enough storage is available to process this command" when generating images

  - by jhericks

  I am running a web application on BEA Weblogic 9.2. Until recently, we were using JDK 1.5.0_04, with JAI 1.1.2_01 and Image IO 1.1. In some circumstances (we never figured out exactly why), when we were processing large images (but not that large - a few MB), the JVM would crash without any error message or stack trace or anything. This didn't happen much in production, but enough to be a nuisance and eventually we were able to reproduce it. We decided to switch to JRockit90 1.5.0_04 and we were no longer able to reproduce the problem in our test environment, so we thought we had it licked. Now, however, after the application server has been up for a while, we start getting the error message, "Not enough storage is available to process this command" during image operations. For example: java.lang.Error: Error starting thread: Not enough storage is available to process this command. at java.lang.Thread.start()V(Unknown Source) at sun.awt.image.ImageFetcher$1.run(ImageFetcher.java:279) at sun.awt.image.ImageFetcher.createFetchers(ImageFetcher.java:272) at sun.awt.image.ImageFetcher.add(ImageFetcher.java:55) at sun.awt.image.InputStreamImageSource.startProduction(InputStreamImageSource.java:149) at sun.awt.image.InputStreamImageSource.addConsumer(InputStreamImageSource.java:106) at sun.awt.image.InputStreamImageSource.startProduction(InputStreamImageSource.java:144) at sun.awt.image.ImageRepresentation.startProduction(ImageRepresentation.java:647) at sun.awt.image.ImageRepresentation.prepare(ImageRepresentation.java:684) at sun.awt.SunToolkit.prepareImage(SunToolkit.java:734) at java.awt.Component.prepareImage(Component.java:3073) at java.awt.ImageMediaEntry.startLoad(MediaTracker.java:906) at java.awt.MediaEntry.getStatus(MediaTracker.java:851) at java.awt.ImageMediaEntry.getStatus(MediaTracker.java:902) at java.awt.MediaTracker.statusAll(MediaTracker.java:454) at java.awt.MediaTracker.waitForAll(MediaTracker.java:405) at java.awt.MediaTracker.waitForAll(MediaTracker.java:375) at SfxNET.System.Drawing.ImageLoader.loadImage(Ljava.awt.Image;)Ljava.awt.image.BufferedImage;(Unknown Source) at SfxNET.System.Drawing.ImageLoader.loadImage(Ljava.net.URL;)Ljava.awt.image.BufferedImage;(Unknown Source) at Resources.Tools.Commands.W$zw(Ljava.lang.ClassLoader;)V(Unknown Source) at Resources.Tools.Commands.getContents()[[Ljava.lang.Object;(Unknown Source) at SfxNET.sfxUtils.SfxResourceBundle.handleGetObject(Ljava.lang.String;)Ljava.lang.Object;(Unknown Source) at java.util.ResourceBundle.getObject(ResourceBundle.java:320) at SoftwareFX.internal.ChartFX.wxvw.yxWW(Ljava.lang.String;Z)Ljava.lang.Object;(Unknown Source) at SoftwareFX.internal.ChartFX.wxvw.vxWW(Ljava.lang.String;)Ljava.lang.Object;(Unknown Source) at SoftwareFX.internal.ChartFX.CommandBar.YWww(LSoftwareFX.internal.ChartFX.wxvw;IIII)V(Unknown Source) at SoftwareFX.internal.ChartFX.Internet.Server.xxvw.YzzW(LSoftwareFX.internal.ChartFX.Internet.Server.ChartCore;Z)LSoftwareFX.internal.ChartFX.CommandBar;(Unknown Source) at SoftwareFX.internal.ChartFX.Internet.Server.xxvw.XzzW(LSoftwareFX.internal.ChartFX.Internet.Server.ChartCore;)V(Unknown Source) at SoftwareFX.internal.ChartFX.Internet.Server.ChartCore.OnDeserialization(Ljava.lang.Object;)V(Unknown Source) at SoftwareFX.internal.ChartFX.Internet.Server.ChartCore.Zvvz(LSoftwareFX.internal.ChartFX.Base.wzzy;)V(Unknown Source) Has anyone seen something like this before?

• Doubt about adopting CI (Hudson) into an existing automated Build Process (phing, svn)

  - by maraspin

  OUR CURRENT BUILD PROCESS We're a small team of developers (2 to 4 people depending on project) who currently use Phing to deploy code to a staging environment, before going live. We keep our code in a SVN repo, where the trunk holds current active development and, at certain times, we do make branches that we test and then (if successful), tag and export to the staging env. If everything goes well there too, we finally deploy'em in production servers. Actions are highly automated, but always triggered by human intervention. THE DOUBT We'd now like to introduce Continuous Integration (with Hudson) in the process; unfortunately we have a few doubts about activity syncing, since we're afraid that CI could somewhat interfere with our build process and cause certain problems. Considering that an automated CI cycle has a certain frequency of automatically executed actions, we in fact only see 2 possible cases for "integration", each with its own problems: Case A: each CI cycle produces a new branch with its own name; we do use such a name to manually (through phing as it happens now) export the code from the SVN to the staging env. The problem I see here is that (unless specific countermeasures are taken) the number of branches we have can grow out of control (let's suppose we commit often, so that we have a fresh new build/branch every N minutes). Case B: each CI cycle creates a new branch named 'current', for instance, which is tagged with a unique name only when we manually decide to export it to staging; the current branch, at any case is then deleted, as soon as the next CI cycle starts up. The problem we see here is that a new cycle could kick in while someone is tagging/exporting the 'current' branch to staging thus creating an inconsistent build (but maybe here I'm just too pessimist, since I confess I don't know whether SVN offers some built-in protection against this). With all this being said, I was wondering if anyone with similar experiences could be so kind to give us some hints on the subject, since none of the approaches depicted above looks completely satisfing to us. Is there something important we just completely left off in the overall picture? Thanks for your attention &, in advance, for your help!
