• Migrating from CPython to Jython

  - by itsadok

  I'm considering moving my code (around 30K LOC) from CPython to Jython, so that I could have better integration with my java code. Is there a checklist or a guide I should look at, to help my with the migration? Does anyone have experience with doing something similar? From reading the Jython site, most of the problems seem too obscure to bother me. I did notice that: thread safety is an issue Unicode support seems to be quite different, which may be a problem for me mysqldb doesn't work and needs to be replaced with zxJDBC Anything else? Related question: What are some strategies to write python code that works in CPython, Jython and IronPython

• Win32 API Question

  - by Lalit_M

  We have developed a ASP.NET web application and has implemented a custom authentication solution using active directory as the credentials store. Our front end application uses a normal login form to capture the user name and password and leverages the Win32 LogonUser method to authenticate the user’s credentials. When we are calling the LogonUser method, we are using the LOGON32_LOGON_NETWORK as the logon type. The issue we have found is that user profile folders are being created under the C:\Users folder of the web server. The folder seems to be created when a new user who has never logged on before is logging in for the first time. As the number of new users logging into the application grows, disk space is shrinking due to the large number of new user folders getting created. Has anyone seen this behavior with the Win32 LogonUser method? Does anyone know how to disable this behavior?

• Unable to launch the ASP.NET Development server because port '1900' is in use.

  - by Shaul

  I don't know what has got into my computer today. I was developing just fine in VS 2008 and testing my ASP.NET web site on my development server. Then suddenly, out of the blue, I can't run my web site any more! As soon as I hit F5, the message appears: Unable to launch the ASP.NET Development server because port '1900' is in use. And it doesn't matter what port I change to, it's always in use! AAARRRGGGHH!!! I have tried: Changing the port number Restarting Visual Studio Rebooting my machine Installing IIS Clue: My IIS refuses to start. But I didn't have IIS installed when I was happily working earlier, so that is probably not the issue; it might just be highlighting something else... Thanks in advance... Update: after rebooting, IIS does start, but the problem here persists.

• Google Appengine and Python exceptions

  - by Jim

  In my Google Appengine application I have defined a custom exception InvalidUrlException(Exception) in the module 'gvu'. Somewhere in my code I do: try: results = gvu.article_parser.parse(source_url) except gvu.InvalidUrlException as e: self.redirect('/home?message='+str(e)) ... which works fine in the local GAE development server, but raises <type 'exceptions.SyntaxError'>: invalid syntax (translator.py, line 18) when I upload it. (line 18 is the line starting with 'except') The problem seems to come from the 'as e' part: if I remove it I don't get this exception anymore. However I would like to be able to access the raised exception. Have you ever encountered this issue? Is there an alternative syntax?

• Cucumber response object -- PHP environment

  - by trisignia

  Hi, I'm using Cucumber to test a PHP application, and while most everything works without issue, I haven't yet figured out how to retrieve a response object for a request -- I'm looking to test whether a response is successful (code 200) and also to perform some Hpricot parsings of the response body. Right now my env.rb file is pretty simple: require 'webrat' include Webrat::Methods include Webrat::Matchers Webrat.configure do |config| config.mode = :mechanize end And if I put something like this in my step definitions: Given /Debug/ do puts response.to_yaml end I get this error: undefined method `response' for nil:NilClass (NoMethodError) ./features/step_definitions/webrat_steps.rb:11:in `/Debug/' features/versions.feature:4:in `Given Debug' Is anyone familiar with this type of situation? best, Jacob

• Dumping views with mysqldump in the right order.

  - by Bushibytes

  I have a script that backs up our database, which contains multiple tables and views constructed from tables. The command used is: mysqldump -u UserName -ppassword -h hostname DatabaseName dump.sql; I have noticed however that some view definitions are backed up before the definitions of the tables. This causes an issue when restoring using the classic mysql -u UserName -p < dump.sql As when it tries to create the view, the table it needs does not exist yet. It is possible to edit the dump files to be restored, but I was wondering: Is there a way to either make sure that mysqldump backs up the tables and views in the right order? Or is there a way to restore from a dump that will find the right tables to create first (or create sane temporary tables)? Edit for version: mysqldump Ver 10.11 Distrib 5.0.51b, for redhat-linux-gnu (x86_64)

• Problem with UTF-8

  - by Pablo Fernandez

  I'm using castor as an OXM mapper, and I'm having a problem with UTF-8 encoding. The code here shows the issue: //Marshaller configuration ByteArrayOutputStream baos = new ByteArrayOutputStream(); OutputStreamWriter os = new OutputStreamWriter(baos, UTF_8); Marshaller marshaller = new Marshaller(os); marshaller.setSuppressXSIType(true); //Mappings configuration Mapping map = new Mapping(); map.loadMapping(MarshallingService.class.getResource(MAPPINGS_PATH)); marshaller.setMapping(map); //Example //BEFORE MARSHALLING: This prints correctly the UTF-8 Chars object.getName() ; marshaller.marshal(object); //AFTER MARSHALLING: This returns the characters like \435\235\654\345 return baos.toString(UTF_8);

• ExceptionPolicy.HandleException does not install Event Source for Logging in Registry if XBAP run ou

  - by Neo

  I am using the Logging Application Block (of Microsoft Enterprise Library) to log exceptions in the Event Viewer that occur in my WPF XBAP application. If I run the XBAP in the debugger from Visual Studio, an Event Source entry for my application is automatically created in the Registry at: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Eventlog\Application\MyApp This occurs at the point ExceptionPolicy.HandleException() is called. However, if I run the XBAP outside of the IDE directly from the file system or from its published location, the Registry entry isn't added. Therefore, no logging takes place. I can only assume this is a security issue with running XBAP applications and they do not have access to write to the Registry. Is this a setting within my project? Any idea on why this might be happening? Any help much appreciated.

• Winforms ComboBox autocomplete search multiple parts of string

  - by studiothat

  Very similar question to this one... http://stackoverflow.com/questions/522521/autocomplete-for-combobox-in-wpf-anywhere-in-text-not-just-beginning but my issue is for windows-forms rather than WPF. I have a winforms databound combox working great with autocomplete list coming from the data items in the combobox. Of course the client wants it to work "better", and that means that they want the autocomplete to work by searching and showing autocomplete options for any matching (contains()) string not just the starting string (startswith()) I know it's probably not just a property that can be set in the combobox, but can anyone point me in the right direction?

• WebBrowser control not submitting form, IE 7 works

  - by Joel Cunningham

  We are using a WebBrowser control in our win forms application which is running in terminal services. IE 7 is the browser that is installed for the session. We are using WebForms to generate the web pages. If we try and submit a web page in the WebBrowser control it does not work. The submit button does not push down. If we try and submit a web page in IE 7 that is installed on the same machine it works as expected. This is only an issue for one person. The WebBrowser control is working for other users. Any thoughts on how I can debug why the submit button is not submitting for the WebBrowser control? Thanks in advance.

• Modifying SQL Server Schema Collection

  - by Mevdiven

  SQL Server XML Schema Collection is an interesting concept and I find it very useful when designing dynamic data content. However as I work my way through implementing Schema Collections, I find it very difficult to maintain them. Schema Collection DDL allows only CREATE and ALTER/ADD nodes to existing schemes. CREATE XML SCHEMA COLLECTION [ <relational_schema>. ]sql_identifier AS 'XSD Content' ALTER XML SCHEMA COLLECTION [ <relational_schema>. ]sql_identifier ADD 'Schema Component' When you want to remove any node from a schema you have to issue following DDL's. If that schema collection assigned to a table column, you have to alter table to remove schema collection association from that column Drop the schema collection object Re-Create schema collection Alter table column to re-associate schema collection to that column. This is pain when it comes to 100+ of schemes in a collection. Also you have to re-create XML indexes all over again, if any. Any solutions, suggestions, tricks to make this schema collection object editing process easier?

• Opening a local file in Eclipse from the web

  - by Victor Nicollet

  Right now, when I notice a problem on a page on my PHP web site, I have to look at the URL, mentally deduce what file is responsible for displaying that page, then navigate the Eclipse PDT file tree to open that file. This is annoying and uses brain power that could have been applied to solving the issue instead. I would like my PHP web site to display on every page a link that I could click to automatically open the correct file in Eclipse. I can easily compute the complete absolute path for the file I need to open (for example, open C:/xampp/htdocs/controllers/Foo/Bar.php when visiting /foo/bar), and I can make sure that Eclipse is currently open with the correct project loaded, but I'm stuck on how I can have Firefox/Chrome/IE tell Eclipse to open that specific file.

• windows 2008 task scheduled batch file runs forever

  - by phill

  I currently have the following batch running in windows 2008 task scheduler. mysql --user=bobdb --password=letmein --force --named-commands --local-infile=1 --execute="insert into bobdb.attendees (name) values ('bob');insert into bobdb.attendees (name) values ('rick');" It executes nicely when I run it from a command prompt and it executes when I force it to run and it executes when it is scheduled to run. My issue is when it does run, the task scheduler seems to keep it running until it hits a timeout. Is there a command to tell it when it is finished running in the batch file so it doesn't throw a timeout error? thanks in advance

• In Django, what's the best way to handle optional url parameters from the template?

  - by Thierry Lam

  I have the following type of urls which are both valid: hello/ hello/1234/ My urls.py has the following: urlpatterns = patterns('hello.views', url(r'^$', 'index', name='index'), url(r'^(?P<user_id>\d+)/$', 'index', name='index'), ) In my views.py, when I pass user_id to the template, it defaults to 0 if not specified. My template looks like the following, I'm using namespace hello for my hello app: {% url hello:index user_id %} If user_id is not specified, the url defaults to hello/0/. The only way I can think of preventing the default 0 from showing in the url is by an if stmt: {% if user_id %} {% url hello:index user_id %} {% else %} {% url hello:index %} {% endif %} The above will give me hello/ if there are no user_id and hello/1234/ if it's present. Is the above solution the best way to solve this issue?

• Why is my CalendarExtender getting overlapped when rendered?

  - by Dillie-O

  I'm working on a .NET web application and I'm using a CalendarExtender control within it to have the user specify a date. For some reason, when I click the icon to display the calendar, the background seems to be transparent, shown below: I'm using the extender on other pages and do not run into this issue. I'm not sure if it is worth mentioning, but the calendar is nested within a panel that has a rounded corner extender attached to it, as well as the panel below it (where the "From" is overlapping). Within that panel, I do have a div layout setup to create two columns. EDIT: The other thing to note here is that the section that has the name and "placeholders" for nickname are all ASP.NET label controls, if that matters.

• aspnet membeship logon page and https redirect

  - by DefSol

  Hello, I have a gridview control that has on onclick event bound to every cell. Once a user clicks on a cell it directs them to a booking confirmation page and passes 3 url variables. This booking page is behind a aspnet membership and thus if the user is not logged in they are served the login page. The login page has a redirect to https connection in the onload event using the IsSecure property. The issue is once the user logs in, then is returned to the booking confirmation page I lose 2 of the url vars. If I remove the https redirect, everything works fine, but the user logs on on a http connection, which is not cool. Appreciate and help thanks Reuben

• ListView FocusedItem Becomes NULL

  - by Andy and Tyler

  When the program runs, there is a series of ListView forms. We populated one of them with items (as strings) and we check whether the state of selection has changed. Once it's changed, we grab the text of the selected item using FocusedItem.Text. The first time works just fine but when another selection is made, the selected item returns as null. The only way we can temporarily get around this issue is to clear and repopulate the form. The disadvantage is that we lose the highlighted item. There got to be another way around this. Maybe we're not clear on how ListView really works? Any ideas?

• Netbeans not Deploying/Debugging

  - by Triztian

  Hello all, I have this problem, it's the second time it happens to me, I'm using the NB IDE 6.9.1 and after a while I was working fine, but then It stopped deploying my webapp when debugging or running the application, I don't recall messing with the ant build scripts or any strange configurations, it successfully builds the dist folder and *.war file and I am able to deploy it manually, but when I run it through the IDE it deletes the webapp folder webapps/myapp,so I cannot debug it or run it, all I get is ClassNotFoundException for my servlets. I am unsure of what extra information would help to solve this issue Its pretty annoying, I don't know how it got solved the last time, it just "went away" any help is truly appreciated.

• Update to php5.3 breaks connecting to mysql db

  - by bobbyb

  I just updated php to 5.3 and can no longer connect to my remote mysql server. I get the following errors: mysqli_connect(): OK packet 6 bytes shorter than expected mysqli_connect(): (HY000/2000): mysqlnd cannot connect to MySQL 4.1+ using old authentication It seems this has to do with the new mysqlnd driver. Is there a way to force it to use the old libmysql driver. Also, reverting to php5.2.11 doesn't seem to fix the issue which seems to work for most people. Anyone have any suggestions? thanks!
