Is start (Dart server side framework) auto-refresh when one of our source code changed (just like PHP)?
Is bulls_eye, bloodless and express too?
or if they are not, is there any Dart server side framework that able to do that (edit code, then test on the browser, without needing to restart the dart/server program)?
Currently this is not yet possible in Dart. If you change the code you have to restart the app.
I wouldn't expect this to work anytime soon.
A main feature to make this possible is to manipulate the code at runtime. This is planned but as far as I know not yet started.
EDIT
The above mentioned feature is necessary when you want code to be updated without loosing the current state of the application but that is usually not so important on the server because it should be (mostly) stateless anyway.
In Dart there's no need to restart the server app when only the client part changes.
If you really just want to restart the entire server when the code changes you should be able to do that by yourself. Create a console app that loads the server app into an isolate (spawnUri) and watch the source directory for file changes. In the case of a file change shutdown the server-app-isolate and create a new one.

Today I started to write my first web application and I can't pass one step.
Everything works almost fine... I can connect to the server and open website. Problem is when I open browser and type the same address on the second pc, then I get te same data as on the first one.
Detailed...
Application has two forms, first is for login, and second one is for receiving data.
When I login on the first pc and second form shows up, and then I open browser and put the address of the server on the second pc, I see the second form after login from first pc.
What I should do in this case? I tried to find the solution in the net, but I couldn't :(
If you are using any Delphi IDE after XE3 (including) and using the IntraWeb edition that comes with Delphi you must upgrade in order to have it working correctly. It is free, and more information can be obtained here:
http://atozed.com/IntraWeb/Download/FreeKeyRequest.EN.aspx|
After upgrading (if this is your case) I suggest you to take a look at one of the IntraWeb demos, here:
https://iwdemos.codeplex.com/SourceControl/latest
There is a demo named Features that shows you exactly how to create a multi form application. To be honest, I work with IntraWeb for a long time and I've never seen that. Unless you are using some global var to hold your "current" active form. Have in mind that IntraWeb is a fully multithreaded application and global vars should not be used, unless you have some mechanism protecting concurrent access (but you should get rid of them and use ServerController properties instead).
Thnks for your quick reply.
I work with Delphi from some time, but I never used Intraweb, I worked with ComPort and IP works for I/O devices. I have XE7 and I upgraded Intraweb to 14.0.52.
I can't find a good file exchange server to put my application for sharing with you. If I find somethin I will post it below.
You can check the code and other settings of my simply project. I put the web application inside the link below, it is without the .exe file.

I'm using Microsoft's Web Deploy Remote Agent service to allow me to easily publish code to the server from within Visual Studio.
The web site I am deploying is using log4net to log messages to log files, and every time I try to deploy a new version of the code, I get this error in Visual Studio stating that the current log4net log file is in use:
An error occurred when the request was processed on the remote
computer. The file 'Web.log' is in use.
The process cannot access 'C:\inetpub\wwwroot\Logs\Web.log' because it
is being used by another process.
I can solve this by going onto the server and doing an iisreset before publishing... but that is kind of defeating the point of 'easy' publishing from Visual Studio :)
Is there some way I can get the publish task to issue an iisreset automatically, or some other way I can work round this?
I kept poking around and found some tidbits around the file being locked in a few other forums. Have you tried adding
<lockingModel type="log4net.Appender.FileAppender+MinimalLock" />
To your <appender> element in the web.config file? From the Apache docs
Opens the file once for each AcquireLock/ReleaseLock cycle,
thus holding the lock for the minimal amount of time. This method of
locking is considerably slower than FileAppender.ExclusiveLock but
allows other processes to move/delete the log file whilst logging
continues.
As far as the performance considerations, I suppose you would need to test if this will affect you or not as I am assuming it really depends on how often you are writing to the log file as to how much this will impact performance. I can't believe that getting/releasing a lock could take all that much time though.
There is a MSDEPLOY provider called recycleApp which is used exactly for this. You can include this in your deployment manifest.
Another option is to use ignoreOnErrors flag which will skip the file in use and continue with the deployment.
Whenever a specific Windows service fails I want to run a program I've created myself. However, I simply can't find a way to make it fail on purpose, so that I can actually test that everything works correctly.
Note that the service in question is not something I've written myself, so I can't make it fail programmatically from inside the code. I wouldn't, however, mind writing a program that can make a service fail.
Of course I would prefer just having a "Make service fail" button somewhere in services.msc ... ;)
The server I'm doing this on is running Windows Server 2012.
If you don't want to use command line :
As an admin open the Windows Task Manager, in the Services tab find the service you want to test. Right click the service and click on Go to process. The selected process (if any) is the one corresponding to your service. Kill this process to simulate a service failure.
Be aware that killing a process this way can lead to problems.
Define "fail". If you want the process to end, just use pskill or a similar tool that can terminate a process elevated (as an admin).
I'm currently developing three workflows that are supposed to handle the status of items in different lists.
Each Workflow is attached to a separate list.
When I'm deploying and debugging in my development Environment, everything works fine.
Except for the case, when an item is created via an incoming mail.
I already figured out, that I have to restart some services and then it'll work, but I'm still not sure wich of the services is caching the workflow.
Afterwards I build a .wsp file which I deploy on a server.
Each time I deploy the solution, I do a retract and delete solution first.
After deployment I'll recreate the workflows on the lists
It seems to me that this has no effect. An older version of the workflow is still triggered, if I create a new instance in the list.
I already restarted the whole server and still no result.
Has anyone an idea what else I could try in order to get this working?
Thanks in advance.
If Timer Service is the one that calls your code, then restart Windows SharePoint Services Timer (OWSTIMER.EXE).
When workflow waits on something, it gets serialized (hydrated). When event happens, OWSTIMER.EXE deserializes (dehydrates) and continues workflow execution.
So timer is the one that wakes workflow up.
So this problem kind of resolved itself.
I was reading an article on Kirk Evanns Blog on an issue with the development of workflows in VS2008 for WSS.
I had not realized that I still had an illeagle reference in my Project properties.
I removed the reference. The second thing I tried was deploying with -upgradesolution rather than doing a retract-delete-add-deploy...
I don't know which of both did the trick, but I can finally see the new workflows kicking in.
Thanks for your help.
I'm developing a card-game in Ruby on Rails, and trying to work out how best to test it.
When a player joins a game, their Player object is stored in the session. Obviously, in order for the game to work, I need more than one Player in a game at once. Since sessions are the same for different tabs in one browser, I'm currently testing a 2-player game by having the app open in FireFox and Internet Explorer at the same time.
Before I go off and download Chrome in order to test a third player... is there an easier way of doing this?
Edit: To clarify, I'm not yet at the stage where I want to run automated tests to see if it breaks. I'm at the stage where I want to be able to hack the back-end db, then refresh the page and see how it looks now, or click a button to see the (usually) failure response, or whether the behaviour is looking right.
You can run Firefox with multiple profiles. From a command line go to the directory Firefox is installed in and run firefox -P. Create a profile for every instance that you want to run. Close the profile manager, then for each profile run firefox -no-remote -P "profile name". You can run as many instances of Firefox as you want, and each one runs with an independent profile and thus independent session.
Automate it!
You really don't want to be manually testing this. You could use a Ruby script with the curl libs to generate the 'moves' and manage the response including the session cookie.
As a teaser, see this snippet from the API docs, sounds like it would help you..
easy.cookiejar = "cookiejar.file" => "pwd string"
Set a cookiejar file to use for this Curl::Easy instance.
This file will be used to persist cookies.
Use http://watir.com/ to create ruby scripts exercising your game.
Use multiple Watir::Browser instances to run multiple browsers.
Use firefox' profiles and -no-remote switch to keep them separated. See also this question.
Rather than opening a new tab, create a new window in your Web browser. The new window will have its own session. This works for Internet Explorer, but not for Firefox. I haven't tested it in the WebKit based browsers.
