  - by Haxed

  In the code below, I've added two lines that print output. The first line prints junk as usual, but surprisingly the second one gives me a compilation error. Why? class Student { private String name; public Student(String name){ this.name = name; } public String getName(){ return name; } } class StudentServer { public StudentServer(){ Student[] s = new Student[30]; s[0] = new Student("Nick"); // LINE 01: This compiles, although prints junk System.out.println(s[0]); // LINE 02: I get a error called cannot find symbol System.out.println(s[0].getName()); } public static void main(){ new StudentServer(); } } Many Thanks

• Contacts activity doesn't return data

  - by Mike

  In my app I simply open the list of activities and when a contact is clicked I attempt to retrieve the name of the contact selected and put it into a string. The app crashes in the onActivityResult() function. I do have the READ_CONTACTS permission set. /** * Opens the contacts activity */ public void openContacts() { Intent intent = new Intent(Intent.ACTION_PICK, People.CONTENT_URI); startActivityForResult(intent, PICK_CONTACT); } @Override public void onActivityResult(int reqCode, int resultCode, Intent data) { super.onActivityResult(reqCode, resultCode, data); switch (reqCode) { case (PICK_CONTACT) : if (resultCode == Activity.RESULT_OK) { Uri contactData = data.getData(); Cursor c = managedQuery(contactData, null, null, null, null); //NullPointerException thrown here, line 102 if (c.moveToFirst()) { String name = c.getString(c.getColumnIndexOrThrow(People.NAME)); FRIEND_NAME = name; showConfirmDialog(name); } } break; } } The following logcat error logs are returned: Any help is appreciated.

• Sorting related objects in the Django Admin form interface

  - by Carver

  I am looking to sort the related objects that show up when editing an object using the admin form. So for example, I would like to take the following object: class Person(models.Model): first_name = models.CharField( ... ) last_name = models.CharField( ... ) hero = models.ForeignKey( 'self', null=True, blank=True ) and edit the first name, last name and hero using the admin interface. I want to sort the objects as they show up in the drop down by last name, first name (ascending). How do I do that? Context I'm using Django v1.1. I started by looking for help in the django admin docs, but didn't find the solution As you can see in the example, the foreign key is pointing to itself, but I expect it would be the same as pointing to a different model object. Bonus points for being able to filter the related objects, too (eg~ only allow selecting a hero with the same first name)

• Adding anchors to h2 in text using python and regexp

  - by Oli

  I'm trying to add anchors to all h2's in my html, using python. This code will add those anchors, but I need to fill the name of the anchors too. Any idea if the name can be the number of the match in the loop or a slugified version of the text between the h2 tags? Here's the code so far: regex = '(?P<name><h2>.*?</h2>)' text = re.sub(regex, "<a name=''/>"+r"\g<name>", text)

• Why Solr admin query page interprets UTF-8 as ISO-8859-1

  - by Scott Chu

  I deploy a war to my Tomcat 6.0.35 on Win7 64bit and when I use full-interface query page (I mean form.jsp) in Solr Admin to query 2 Chinese character (say it's C1C2) , the debug info shows: <lst name="debug"> <str name="rawquerystring">æ°è</str> <str name="querystring">æ°è</str> <str name="parsedquery">NEWSID:æ°è</str> <str name="parsedquery_toString">NEWSID:æ°è</str> ... You can see C1C2 becomes æ°è. I deploy same war file to Tomcat on Linux or on another Win7 64bit of my colleagues' computer, the encoding acts well. Does anyone know why and how can I avoid this problem? Thanks in advance!

• Programmatically scroll to an Anchor Tag

  - by Anders

  Consider the following code: <a href="#label2">GoTo Label2</a> ... [content here] ... <a name="label0"></a>More content <a name="label1"></a>More content <a name="label2"></a>More content <a name="label3"></a>More content <a name="label4"></a>More content Is there a way to emulate clicking on the "GoTo Label2" link to scroll to the appropriate region on the page through code? EDIT: An acceptable alternative would be to scroll to an element with a unique-id, which already exists on my page. I would be adding the anchor tags if this is a viable solution.

• Which technologies will most affect Financial Services over the next decade? [on hold]

  - by opposite of you

  I couldn't quite think of a proper description, so as Wikipedia puts it so beautifully: Financial services are the economic services provided by the finance industry, which encompasses a broad range of organizations that manage money, including credit unions, banks, credit card companies, insurance companies, consumer finance companies, stock brokerages, investment funds and some government sponsored enterprises. These are quite a range of industries. I've already thought about how banks specifically have gotten involved with app markets allowing users to make transfers on the go, and this goes with cloud computing, but what else could there be apart from mobile technologies and cloud computing? Or how else could they be used? I feel like I'm thinking about this wrong.. Apart from mobile computing and cloud computing, what other examples will influence the sector either positively or negatively?

• Different RegisterWindowMessage() names appear the same

  - by Mike Trader

  Using the C/C++ Windows API RegisterWindowMessage() I am using the name of the application as the message name. Next I call CreatMutex() using the same name so that I can tell if it already exists. If it does, I know this application is already running and not to launch a second instance of it. THis is the operation of my function Running() My confusion is over the message name. It seems that "AutoConvert.exe" and "AutoAppend.exe" are interpreted as the same name. Why?

• Is this the best way to get the size of a Paper via CUPS?

  - by Lawrence Johnston

  I've got a CUPS job control file. I need to get the actual dimensions of the print that was made. This is the way I've figure out to do it: Get the paper name using the media attribute. (e.g. Letter) Get the printer uri from the printer-uri attribute. (e.g. ipp://localhost/printers/MyPrinter) Get the printer name by passing the printer uri to the IPP_GET_PRINTER_ATTRIBUTES operation and getting the printer-name attribute. (e.g. MyPrinter) Get the path to the PPD passing the printer name to the the cupsGetPPD method. Open the PPD passing the path to the PPD to the ppdOpenFile method. Get the paper size by passing the PPD and paper name to the ppdPageSize method. This will work, but it seems a bit roundabout. Is there a more efficient way of getting what I need?

• ASP.NET MVC Model Binders, html id

  - by Stacey

  Using the Model Binders in ASP.NET MVC 2.0, you can do something like this... [DisplayName("User Name")] public string Name { get; set; } <%: Html.TextBoxFor( m => m.Name ) :%> and then in your HTML, you get a result like this.. <label for="UserName">User Name</label> <input type="text" id="UserName" name="UserName" /> That works fine, but I want to have better control over the HTML ID. Is there any way to do this through the model binding method?

• Is it possible to select data with max value for a column using Criteria in Hibernate?

  - by Palo

  Lets say I have the following mapping: <hibernate-mapping package="mypackage"> <class name="User" table="user"> <id name="id" column="id"> <generator class="native"></generator> </id> <property name="name" /> <property name="age" /> </class> </hibernate-mapping> Is it possible to select the oldest user (that is age is maximal) using Criteria in Hibernate? I can imagine that i could do this with 2 selects. (first select total number of users and then order the entries descending by age and select the first entry). But is it possible with a single select? Thank you Palo
