NHibernate - get List<long> representing primary keys?

- by Nathan

I have a situation where I definitely don't want to get the whole domain object. Basically, the entity has a primary key of long (.NET)/bigint(sql server 2005). I simply need to pass the primary key to an external system which will access the database directly - and since the list of ids could be large, I don't want to rehydrate the entire domain object just to get the Id. In linq2sql, I could accomplish this with a projection, but I am restricted to NHibernate 1.2.1.4000, which doesn't support Linq. Is there a way to accomplish this using NHibernate 1.2.1.4000? (I am open to using a named-query if that will work)

But how to put it all together? Regards!

Convert XML to .plist

- by Dror Sabbag

Hey, I have an XML exported from Oracle DB, which will be downloaded into my application main bundle. i would like to convert this XML file into .plist file so i can assign the values into NSDictionary and NSArrays.. Is there a way to get this to work? or is there a better way to work with an external XML file? note that one of the fields in the XML is a full HTML content example: <main> <DATA_RECORD> <ID>ID1</ID> <NO>1234512</NO> <TYPE>NEW</TYPE> <TYPE_NO>0</TYPE_NO> <TEXT_ID>TEXT1</TEXT_ID> <TEXT><HTML>some html goes here</HTML></TEXT> </DATA_RECORD> </main>

Create a triangle out of stars using only recursion

- by Ramblingwood

I need to to write a method that is called like printTriangle(5);. We need to create an iterative method and a recursive method (without ANY iteration). The output needs to look like this: * ** *** **** ***** This code works with the iterative but I can't adapt it to be recursive. public void printTriangle (int count) { int line = 1; while(line <= count) { for(int x = 1; x <= line; x++) { System.out.print("*"); } System.out.print("\n"); line++; } } I should not that you cannot use any class level variables or any external methods. Thanks.

import existing source code as referenced library in eclipse

- by user555174

I have some source codes from a friend that I would like to use as referenced library in my BlackBerry project. I'm not sure about how to package the source codes into a .jar file. I tried exporting the source to a JAR file and import it as external JAR in my project, it's giving me missing stack map error. I tried to preverify the .jar file generated from the source using the provided preverification tool from BlackBerry JDE, it didn't give me any output folder. In fact, I'm not sure if the way I export the source is correct. Can anyone provide step-by-step instructions on how to package existing source code into a valid JAR file that can be imported into my project as a referenced library? Again, I'm using eclipse. Thanks very much in advance.

preventing window blur/focusOut when selecting copy/paste menu

- by jedierikb

I am trying to determine when the user has moved focus out of the browser to: select copy/paste (but not to the google search box). Ffox handles this nicely. selecting another window/tab/external widget (e.g., the google search box). focusOut and blur listeners on window and document cannot seem to disambiguate between these two types of focus changes. Can IE do this? I want this distinction so that I can better support usability in my web app without losing focus.

How to test the XML sent to a web service in Ruby/Rails

- by Jason Langenauer

I'm looking for the best way to write unit test for code that POSTs to an external web service. The body of the POST request is an XML document which describes the actions and data for the web service to perform. Now, I've wrapped the webservice in its own class (similar to ActiveResource), and I can't see any way to test the exact XML being generated by the class without breaking encapsulation by exposing some of the internal XML generation as public methods on the class. This seems to be a code smell - from the point-of-view of the users of the class, they should not know, nor care, how the class actually implements the web service call, be it with XML, JSON or carrier pigeons. For an example of the class: class Resource def new #initialize the class end def save! Http.post("http://webservice.com", self.to_xml) end private def to_xml # returns an XML representation of self end end I want to be able to test the XML generated to ensure it conforms to what the specs for the web service are expecting. So can I best do this, without making to_xml a public method?

Exception while trying to deserialize JSON into EntityFramework using JavaScriptSerializer

- by Barak

I'm trying to deserialize JSON which I'm getting from an external source into an Entity Framework entity class using the following code: var serializer = new JavaScriptSerializer(); IList<Feature> obj = serializer.Deserialize<IList<Feature>>(json); The following exception is thrown: Object of type 'System.Collections.Generic.List1[JustTime.Task]' cannot be converted to type 'System.Data.Objects.DataClasses.EntityCollection1[JustTime.Task]'. My model is simple: The Feature class has a one-to-many relation to the Tasks class. The problem appears to be the deserializer is trying to create a generic List to hold the collection of tasks instead of an EntityCollection. I've tried implementing a JavaScriptConverted which would handle System.Collections.Generic.List but it didn't get called by the deserializer.

How to Embed Image in Outlook Signature?

- by BlackMael

Is it possible to create an HTML email signature for Outlook 2003 or above that doesn't reference external images? That is, using those special "cid" reference but embed the image itself in the signature and not on the file system or network. This is for an web application that generates a "standard" email signature based on various input from a user. It has worked fine so far with a single "embedded" image. But a new feature is going to require the possible addition of multiple tiny images. Getting to user to save one email signature template and one image to the user's machine is about the limit of what I'd like to require of the user. But forcing the user to save multiple images seem to be pushing things a little to far in my opinion. So my problem is trying to embed the images into without having to inconvenience the user with multiple downloads first.

Best way to style GWT widgets in a library

- by helios

I'm developing some widgets into a library for internal use at the company I work for. I don't know what's the recommended way to style the widgets. There are at least these ways: use Widget.setPrimaryStyleName and let the user provide an external css. We use maven archetypes to build applications so we can provide default styles. Anyway I don't like it very much. use the GWT 2.0 CssResourceBundle. So we can compile the CSS into the module and it will be optimized (and it can be browser-dependant too). provide a module with the styling. Something like the default GWT themes. But I don't know how exactly this works. I want to: make the components as cohesive as I can (don't depend on externally included css's) leave open the door to modify styles (if I want to change the way some widget looks in a concrete application). What's your experience in this subject?

Poster image on embedded youtube video

- by Srijan Deshpande

Hi, I want to embed a youtube video on my website and I need to replace the default poster image that shows up on the video with a jpg of my own. The default image that shows up is a scaled-up thumbnail and is therefore very blurry and pixelated and I need to use a hi-res jpg in place of it. I'm aware that youtube only allows us to pick one of three auto-generated thumbnails, but does that restriction also apply to youtube videos embedded on an external website? If so, is there an alternate way to do this? Thanks!

Is git suitable for one developer without server

- by Shawn Mclean

I am a single developer without another computer to backup my projects on. I'm looking into source controls and I came across git but all the setup tutorials are targeted to an external server. I used to use SourceGear Vault, but seeing that git is getting alot of attention, I might as well familiarize myself with it. I do not always have internet access. Is Git suitable for me? Can I be pointed in the right direction to set it up? Visual Studio 2008. Windows 7.

PHP e-commerce site talking to internal database for stock / ordering?

- by CitrusTree

Hi. I'm working on an e-commerce site (either bespoke with PHP, or using Drupal/Ubercart), and I'd like to investigate the site interacting with an internal (filemaker) database we use to manage stock and orders. Currently we manually transfer orders from the web site to our own database, and the site does not check or record changes in stock. My plan to allow the 2 to interact is as follows: Make the internal database available externaly on a machine with a fixed IP Allow external access from the site only Connect to the internal database using ODBC (or similar) Use simple queries to check stock / record stock changes / record order details Am I missing something here as this sounds quite straight forward? Is there another solution I should be taking a look at? Thanks in advance for any help or comments.

Want procmail to run a custom python script, everytime a new mail shows up

- by Maddy

I have a pretty usual requirement with procmail but I am unable to get the results somehow. I have procmailrc file with this content: :0 * ^To.*@myhost | /usr/bin/python /work/scripts/privilege_emails_forward.py Wherein my custom python script(privilege_emails_forward.py) will be scanning through the email currently received and do some operations on the mail content. But I am unable to get the script getting executed at the first shot(let alone scanning through the mail content). Is this a correct way of invoking an external program(python) as soon as new mail arrives? And how does my python program(privilege_emails_forward.py) will receive the mail as input? I mean as sys.argv or stdin????

The difference between the 'Local System' account and the 'Network Service' account?

- by jmatthias

I have written a Windows service that spawns a separate process. This process creates a COM object. If the service runs under the 'Local System' account everything works fine, but if the service runs under the 'Network Service' account, the external process starts up but it fails to create the COM object. The error returned from the COM object creation is not a standard COM error (I think it's specific to the COM object being created). So, how do I determine how the two accounts, 'Local System' and 'Network Service' differ? These built-in accounts seem very mysterious and nobody seems to know much about them.

ASP.NET MVC How to call a secured page from a windows app?

- by Malcolm

Hi, I have a MVC app that has forms authentication enabled. The app allows printing of invoices. I have an external app that converts html to pdf. How can I call the secured page from this pdf converter app so that some security remains? The PDF converter app just requires a URL. One thought was to create a HttpHandler for an extenion of say .print and pass a public key in the URL qureystring that can be validated by the MVC app. Any ideas on this? Malcolm

Why is distributed source control considered harder?

- by Will Robertson

It seems rather common (around here, at least) for people to recommend SVN to newcomers to source control because it's "easier" than one of the distributed options. As a very casual user of SVN before switching to Git for many of my projects, I found this to be not the case at all. It is conceptually easier to set up a DCVS repository with git init (or whichever), without the problem of having to set up an external repository in the case of SVN. And the base functionality between SVN, Git, Mercurial, Bazaar all use essentially identical commands to commit, view diffs, and so on. Which is all a newcomer is really going to be doing. The small difference in the way Git requires changes to be explicitly added before they're committed, as opposed to SVN's "commit everything" policy, is conceptually simple and, unless I'm mistaken, not even an issue when using Mercurial or Bazaar. So why is SVN considered easier? I would argue that this is simply not true.

.htaccess rewrite subdomains

- by Cyclone

Here is my current code: RewriteCond %{HTTP_HOST} !^example\.com [NC] #RewriteCond %{REQUEST_URI}!^something RewriteCond %{HTTP_HOST} ^([^.]+)\.example\.com RewriteRule (.*) something/%1/$1 [QSA,L] My goal is to rewrite http://*.example.com/whatever to http://example.com/something/*/whatever, assuming * is the same for both and whatever is the same for both. However, I believe this is causing an infinite loop somehow, so I added that commented out line (RewriteBase is / btw), but if I uncomment then the entire site is a 500 response code. Without that line, only the subdomains error. What am I doing wrong, and how can I fix this? I have already configured the server so anything gets redirected to my public_html folder. EDIT: For clarification, I am trying to do an internal redirect, not external. EDIT: There is not a flag for internal redirect it seems. Is there any place I can see the actual error message for the broken rewriterule? If I knew what was wrong I would be able to stand a better chance of fixing it.

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)

How do I run JUnit tests from inside my java application?

- by corgrath

Is it possible to run JUnit tests from inside my java application? Are there test frameworks I can use (such as JUnit.jar?), or am I force to find the test files, invoke the methods and track the exceptions myself? The reason why I am asking is my application requires a lot of work to start launch (lots of dependencies and configurations, etc) and using an external testing tool (like JUnit Ant task) would require a lot of work to set up. It is easier to start the application and then inside the application run my tests. Is there an easy test framework that runs tests and output results from inside a java application or am I forced to write my own framework?

Emacs: adding 1 to every number made of 2 digits inside a marked region

- by WizardOfOdds

Imagine I've got the following in a text file opened under Emacs: some 34 word 30 another 38 thing 59 to 39 say 10 here 47 and I want to turn into this, adding 1 to every number made of 2 digits: some 35 word 31 another 39 thing 60 to 40 say 11 here 48 (this is a short example, my actual need is on a much bigger list, not my call) How can I do this from Emacs? I don't mind calling some external Perl/sed/whatever magic as long as the call is made directly from Emacs and operates only on the marked region I want. How would you automate this from Emacs? I think the answer I'm thinking of consist in calling shell-command-on-region and replace the region by the output... But I'm not sure as to how to concretely do this.

Test Jboss JMS externally - outside of the application server

- by bmatsliah

Hi All, I'm pretty new to the JMS functionality. I need to test a remote JMS which is on Jboss 4.2.1. I want to develop an external test (e.g from a main class) which sends and receives messages to/from the app. server. (I do have full access to the remote server.) My questions are: 1) How do I send messages to the Jboss JMS? 2) Where is the information needed to send a message located on the Jboss? ip, port, queue, user, pw, ect. to set up the local messaging test. 3) Is there a way to config/ develop a mechanism on the remote JMS Jboss server that sends back acknowledgments to the sender (in this case)? I greatly appreciate your help. Thanks, Ben

getResourceAsStream not loading resource

- by Michal Gorecki

The project that I am currently working on utilizes an old application contained within a .jar file. One of the responsibilities of this application is that it updates the database when changes to the configuration files are made. Every time I try to run this file (which is a simple Ant Task extension), I get an exception thrown early in the process. I decompiled the Java file responsible, and found that the exception being thrown happens here. I do not know what the issue is, as "hibernate.cfg.xml" is contained within the same .jar file as the .class throwing the exception. ClassLoader loader = Thread.currentThread().getContextClassLoader(); InputStream in = loader.getResourceAsStream("hibernate.cfg.xml"); if (in == null) { throw new RuntimeException("Couldn't find built in hibernate config"); } If anyone has any ideas, even pointing me in the right direction, I would be grateful. Of course, any solution will have to be external, as the client already has this build of the program in production use.
