• How to setup Main class in manifest file in jar produced by NetBeans project

  - by Leni Kirilov

  I have the following problem. I have a Java project in my NetBeans IDE 6.8. When I compile it and it produces a .jar file containing everything possible, the META-INF is not right. It doesn't contain the class to be executed - with main() method. When I click the Run button inside the IDE, everything works. The settings of the project are also set the right way - pointing to a class in my project. I tried adding a folder META-INF with manifest file but I didn't manage. Is there a way to do this manually in NetBeans, because I found that if I add the missing Main class in the manifest, everything works.

• Rails migrations: Undo default setting for a column

  - by wulfovitch

  Hi Stack Overflow Community! I have the problem, that I have an migration in Rails that sets up a default setting for a column, like this example: def self.up add_column :column_name, :bought_at, :datetime, :default => Time.now end Suppose, I like to drop that default settings in a later migration, how do I do that with using rails migrations? My current workaround is the execution of a custom sql command in the rails migration, like this: def self.up execute 'alter table column_name alter bought_at drop default' end But I don't like this approach, because I am now dependent on how the underlying database is interpreting this command. In case of a change of the database this query perhaps might not work anymore and the migration would be broken. So, is there a way to express the undo of a default setting for a column in rails? Thanks in advance!

• MediaElement seems to disable lock screen when playing a video

  - by CrossProduct

  I am working on an application that plays a video using the MediaElement component. Now, I would like that if the user is idle, the lock screen appears, as configured by the user in the Settings of the device. If I don't play a video, the lock screen indeed appears. But, when a video is playing no lock screen appears. I cannot find any information on this. Currently I set the idle detection modes like this: PhoneApplicationService.Current.ApplicationIdleDetectionMode = IdleDetectionMode.Enabled; PhoneApplicationService.Current.UserIdleDetectionMode = IdleDetectionMode.Enabled; I am a bit lost now. The only solution I can think of is running a timer myself and stop the video playback after a certain time. (but there seems to be no API calls to receive the configured lock timeout.) Any suggestions are welcome, thanks.

• Can I assign a maven dependency to a specific repo?

  - by mds

  So I have several large projects that use up to 8 different external repos, all specified in settings.xml rather than in poms. A lot of our internal dependencies are snapshots, so this obviously causes a lot of checking for updates across several external repos, when they are all in our internal repo. So my question is, is there a way to setup a profile/filter or anything similar where I can ensure that an update will only be checked for in a specific repo(s)? This is all in the spirit of better/quicker builds. Thanks!

• How to use application config file in C#?

  - by badpanda

  I am trying to use a config file in my C# console application. I created the file within the project by going New -- Application Configuration File, and naming it myProjectName.config. My config file looks like this: <?xml version="1.0" encoding="utf-8" ?> <configuration> <appSettings> <add key="SSDirectory" value="D:\Documents and Settings\****\MyDocuments\****" /> </appSettings> </configuration> The code to access it looks like this: private FileValidateUtil() { sSDirFilePath = ConfigurationSettings.AppSettings["SSDirectory"]; if (sSDirFilePath == null) Console.WriteLine("config file not reading in."); } Can anyone lend a hint as to why this is not working? (I am getting the error message.) Thanks!! badPanda

• How can I debug or set a break statement inside an expression tree?

  - by Abel

  When an external library contains a LINQ provider, and it throws an exception when executing a dynamic expression tree, how can I break when that expression is thrown? For example, I use a third party LINQ2CRM provider, which allows me to call the Max<TSource, TResult>() method of IQueryable, but when it throws an InvalidCastException, I fail to break on the spot when the exception is thrown, making it hard to review the stack-trace because it's already unwinded when the debugger breaks it in my code. I've set "break on throw" for the mentioned exception. My debug settings are: Clarification on where exactly I'd want to break. I do not want to break in side the LINQ Expression, but instead, I want to break when the expression tree is executed, or, put in other words, when the IQueryable extension method Max() calls the override provided by the LINQ provider. The top of the stacktrace looks like this, which is where I would like to break inside (or step through, or whatever): at XrmLinq.QueryProviderBase.Execute[T](Expression expression) at System.Linq.Queryable.Max[TSource,TResult](IQueryable`1 source, Expression`1 selector)

• Cannot save model due to bad transaction? Django

  - by Kenneth Love

  Trying to save a model in Django admin and I keep getting the error: Transaction managed block ended with pending COMMIT/ROLLBACK I tried restarting both the Django (1.2) and PostgreSQL (8.4) processes but nothing changed. I added "autocommit": True to my database settings but that didn't change anything either. Everything that Google has turned up has either not been answered or the answer involved not having records in the users table, which I definitely have. The model does not have a custom save method and there are no pre/post save signals tied to it. Any ideas or anything else I can provide to make answering this easier?

• Override .Net Resource file in Calling Application

  - by Blatfrig

  I have an asp.net 2.0 web application that is calling class library. A fairly common scenario to be sure. The class library is making use of a number of resource files and a ResourceManager object to set localised strings. This works absolutely fine in most circumstances based on the user's browser settings. However there are some circumstances under which I wish to overrride the resource string in the class library from within the web application. Is this possible? if so how?

• Using Tortoise SVN with C++ in Visual Studio 2008

  - by Dr. Monkey

  I have an online repository with some .h and .cpp files that make up part of a project. I'm trying to check these out and use them in a new project, but am getting errors (C4627 and C1010). All the files have been added to the project (with AddExisting Item...), and the subdirectories that contain these files have been added to the "Additional include directories" of the project. Would I be better off having the entire project tree in the repository? My reason for not doing so is that my colleague and I are working on different parts of the code and so want to use different main methods to test things as we go, and I didn't see any need to be passing around any compiled code etc. since I assumed that given the .h and .cpp files (with the correct settings), visual studio would be able to compile the project. What's the best way to make Visual Studio 2008 and TortoiseSVN work well together (without spending any money)?

• How to remove proxy from WebRequest and leave DefaultWebProxy untouched

  - by Elephantik

  I use FtpWebRequest to do some FTP stuff and I need to connect directly (no proxy). However WebRequest.DefaultWebProxy contains IE proxy settings (I reckon). WebRequest request = WebRequest.Create("ftp://someftpserver/"); // request.Proxy is null here so setting it to null does not have any effect WebResponse response = request.GetResponse(); // connects using WebRequest.DefaultWebProxy My code is a piece in a huge application and I don't want to change WebRequest.DefaultWebProxy because it is global static property and it can have adverse impact on the other parts of the application. Any idea how to do it?

• Connect Infopath form To Outlook - shows as xml

  - by gab

  In Sharepoint, i have a Forms Library. I would like to connect it to oulook. The problem is that once I do that, Outlook will display the forms in a .XML rendering...a bunch of text, not very user friendly. (I am using Sharepoint 2010, InfoPath 2010, Outlook 2010) Am I missing some kind of settings? How can I display the forms in Outlook in a rendered type of view. (I have tried this with Forms that open in Browser, as well as with Forms that open in Client application, with the same results for both.)

• Writing a custom auth system (like the default django auth system), use it to generate tables in DB

  - by dotty

  Hay all, I've been reading up on middleware and how to use it with a context object. I want to write a simple middleware class which i can use on my own applications, it will essentially be a cut down version of the django one. The problem i seem to have is that if i have INSTALLED_APPS = ('django.contrib.my_auth') in the settings file, all is well. I've also added MIDDLEWARE_CLASSES = ('django.contrib.my_auth.middleware.MyAuthMiddleware') in it and everything is fine. My question is, how would i make my middleware automatically generate tables from a models.py module, much like how the django auth does when i run manage.py syncdb? thanks

• Feature activate via UI but does not show in the Libraries and Lists

  - by Justin Cullen

  I am really hating SharePoint as there are hardly any good/concrete documentation. I developed custom List "MainCatalog" with few columns (not site columns). Create features and elements with MOSS feature builder at Site collection level so scope="site" installed via stsadm activated via UI "went to site collection website", Site Setting Site collection Feature (and saw my custom list "MainCatalog") and was able to activate. then went to "mySiteCollection Site Settings Site Libraries and Lists " My list is showing But it shows in the "mySiteCollection Create Custom Lists "MainCatalog" I guess it's showing there as a template... But my intention is to deploy this list from development to test environment. EXTREMELY STRESSED. I AM ON THIS FOR LAST 8 DAYS.....

• Django 1.5 custom User model error. "Manager isn't available; User has been swapped"

  - by bpetit

  I extend the django user model as described in the dev doc. I wan't to keep most of the original User model features so I extend the AbstractUser class. I've defined in settings.py: AUTH_USER_MODEL = 'myapp.CustomUser' My user class: class CustomUser(AbstractUser): custom_field = models.ForeignKey('OtherModel') objects = UserManager() Everything seems to work fine but when I try to make it managed by the admin site: admin.site.register(CustomUser, UserAdmin) I get this error on the admin CustomUser creation page (after validation of the password confirmation form): AttributeError: Manager isn't available; User has been swapped for 'myapp.CustomUser' The point is that I need this model managed by the admin site in order to have the same creation process as with the original User model (two step process with password validation). Thanks for any reply

• deploying a simple html website with eclipse EE & tomcat 7 & router for pc not in LAN

  - by hawkeye

  Hello everyone and thanks for your time, first of all - I want to make a note - I can see the website from my own pc which is the only one connected to the (netgear dgn1000) router, and I can do so with several browsers on my pc, but - when I try and do a port forwarding so that I could access this simple html file (which in the way would use a simple servlet class) I can't seem to view it I have configured my router (both the "services" and the "firewall" sections), and I have also changed my LAN properties according to my ISP's explanation (via phone) : instead of choosing the "obtain an IP address automatically" I have chosen the "use the following IP address, with IP address of 10.0.0.1 (this was also set in the router's port forwarding), Subnet mask of 255.255.255.0, default gateway by checking the same value as seen in the cmd when executing the command ipconfig /all after doing so I've changed the DNS to use the address (just the preferred and not the alternate one) given with the ipconfig /all and still - nothing :/ is it something in my network settings or in my deployment of the eclipse/tomcat ? any help would be greatly appreciated, thanks :)

• How to test for secure SMTP mail service on a mail server

  - by Vinay S Shenoy

  I'm working on a project to auto-configure a user's email server settings in Java. I am extracting the mail server from his email address and looking up the MX records of that mail server using the DirContext class with com.sun.jndi.dns.DnsContextFactory. Then I'm opening a Socket to each server and testing them using a HELO command and checking the responses. My problem is that this works only when I test it with the unsecure SMTP port 25. How can I use it with the secure port 465? I tried using Secure Sockets by using SSLSocketFactory sslsocketfactory = (SSLSocketFactory)SSLSocketFactory.getDefault(); SSLSocket socket = (SSLSocket)sslsocketfactory.createSocket(mailserver, STANDARD_SMTP_PORT); But all connections get a timeout exception as follows alt1.gmail-smtp-in.l.google.com. java.net.ConnectException: Operation timed out Please help.

• Change MS Patch custom language

  - by nelusan

  How can I change the default UI language when installing a patch/update? The problem is that the patch takes the initial language in which the setup to be patched was installed and not the current system language (defined in Reginal Settings/Advanced Options). I wonder if there is a property or switch that I can pass to a msp file to change its UI language. Example: I created 'setup_v00.exe' (english and french) and a patch 'update_v00_v01.exe' (english and french); with system language = english, 'setup_v00.exe' installs in english; change system language in french; with system language = french, 'update_v00_v01.exe' still installs in english but I want it to install with a french interface;

• What information about me and my system do compilers add to executeables?

  - by I can't tell you my name.

  I'm currently using Microsoft Visual Studio 2010. If we say that we give 10 different people a copy of MSVC 10 and a short C++ Hello, World listing. They all create a new project using exactly the same settings, add a new cpp file with the Hello, World program and compile it. Do they all get the exactly same binary? If not, what are the exact differences? What information about my system does MSVC add to my executeable? Paranoia!

• Reading web-service information from assembly app.config file

  - by Benjamin Ortuzar

  I have a plugin architecture solution written in .NET C# 3.5, where each plug-in is an assembly loaded by the main project. Each plug-in connects to a different web-service, so I would like to have the configuration of that plugin in its own plugin.dll.config file instead of having it in the app.config of the main project. I have been looking around and I saw that i could load from each class its own config file: // Get the application configuration file. System.Configuration.Configuration config = ConfigurationManager.OpenMappedExeConfiguration(fileMap,userLevel) I see how that would help me get the basic settings from the appSettings section, but I cant see a way to read the web-service information stored in the plugin.dll.config file. Any help on how to approach this situation is very welcome.

• Help: My SSL Certificate expired but I can't renew it until Monday, is there any way I can disable SSL through IIS?

  - by Ryan

  Or perhaps force redirect to HTTP when they request HTTPS? I tried removing the SSL port settings under 'Advanced' but it broke the login page. I don't want to do a deploy/recompile right now but I am able to edit the VIEWS. However I am thinking there may be a way for IIS to do this, but then again I think the .NET code tries to force SSL. And yes, the key is that more support tickets will be caused by the browser giving a security error than if SSL was removed entirely for one day. Becaues they wouldn't very very likely not notice it being gone.

• How to convert an Info.plist file from mac os project to iphone project?

  - by Tom Pace

  I am developing an app for the iPhone OS devices, and am using a third-party engine which is not well documented but I've made great progress with it anyway. The problem: The engine's developer strongly urges extending from the existing template projects bundled with the engine, but the engine's Info.plist files are Mac OSX project Info.plist files. This is an iPhone engine, and so I cannot understand why the Info.plist file is structured to take keys for Mac OS apps, but that's how it is. I did a FileMerge comparison to ensure there was nothing within the file itself that defined its use for one OS or the other, so I guess it's defined somewhere in the project settings. Edit - Opening the plist file in Xcode or Property List Editor and then trying to add a key such as "Icon already includes gloss and bevel effects" will not work in this iPhone project because it is not in the list. However, "Cocoa Java Application" and others are available!
