• What is the proper location for a sqlite3 database file?

  - by Elliot Chen

  Hi, Everyone: I'm using a sqlite3 database to store app's data. Instead of building a database within program, I introduced an existing db file: 'abc.sqlite' into my project and put it under my 'Resources' folder. So, I think this db file should be inside of 'bundle', so at my init function, I used following statement to read it out: NSString *path = [[NSBundle mainBundle] pathForResource:@"abc" ofType:"sqlite"]; if(sqlite3_open([path UTF8String], &database) != SQLITE_OK) ... It's ok that this db can be opened and data can be retrieved from it. BUT, someone told me that it's better to copy this db file into user folder: such as 'Document'. So, my question is: is it ok to use this db from main bundle directly or copy it to user folder then use that copy. Which is better? Thank you very much!

• R.java file not updating with UI element's id

  - by Mohit Deshpande

  I added some UI elements to the main.xml file in the res\layout folder and when I try to access them through the call, R.layout.my_uielement, the UI element that I created is not there. Even when I add a new xml file with UI elements, it still doesn't show up in the R.layout class. I have made checked the ids on them and they have the correct format (I think): android:id="@+id/my_button". What could be the problem? Do I need to compile the code first?

• I've created a database table using Visual Studio for my C# program. Now what?

  - by Kevin

  Hi! I'm very new to C#, so please forgive me if I've overlooked something here. I've created a database using Visual Studio (add new item service-based database) called LoadForecast.mdf. I then created a table called ForecastsDB and added some fields. My main question is this: I've created a console application with the intention of writing some data to the newly created database. I've added LoadForecast.mdf as a data source for my program, but is there anything else I should do? I saw an example where the next step was adding a "data diagram", but this was for a visual application, not a console application. Do I still need to diagram the database for my console app? I just want to be able to write new records out to my database table and wasn't sure if there were any other things I needed to do for the VS environment to be "aware" of my database. Thanks for any advise!

• IWebBrowser2: how to force links to open in new window?

  - by Rob McAfee

  The MSDN documentation on WebBrowser Customization explains how to prevent new windows from being opened and how to cancel navigation. In my case, my application is hosting an IWebBrowser2 but I don't want the user to navigate to new pages within my app. Instead, I'd like to open all links in a new IE window. The desired behavior is: user clicks a link, and a new window opens with that URL. A similar question was asked and answered here and rather than pollute that answered post, it was suggested I open a new discussion. The members on the related post suggested I should be able to do this by trapping DISPID_BEFORENAVIGATE2, setting the cancel flag, and writing code to open a new window, but I've found out that the browser control gets lots of BeforeNavigate2 events that seem to be initiated by scripts on the main page. For example, amazon.com fires BeforeNavigate2 events like crazy, and they are not a result of link invocation. Replies appreciated!

• Unittest and mock

  - by user1410756

  I'm testing with unittest in python and it's ok. Now, I have introduced mock and I need to resolve a question. This is my code: from mock import Mock import unittest class Matematica(object): def __init__(self, op1, op2): self.op1 = op1 self.op2 = op2 def adder(self): return self.op1 + self.op2 def subs(self): return abs(self.op1 - self.op2) def molt(self): return self.op1 * self.op2 def divid(self): return self.op1 / self.op2 class TestMatematica(unittest.TestCase): """Test della classe Matematica""" def testing(self): """Somma""" mat = Matematica(10,20) self.assertEqual(mat.adder(),30) """Sottrazione""" self.assertEqual(mat.subs(),10) class test_mock(object): def __init__(self, matematica): self.matematica = matematica def execute(self): self.matematica.adder() self.matematica.adder() self.matematica.subs() if __name__ == "__main__": result = unittest.TextTestRunner(verbosity=2).run(TestMatematica('testing')) a = Matematica(10,20) b = test_mock(a) b.execute() mock_foo = Mock(b.execute)#return_value = 'rafa') mock_foo() print mock_foo.called print mock_foo.call_count print mock_foo.method_calls This code is functionally and result of print is: True, 1, [] . Now, I need to count how many times are called self.matematica.adder() and self.matematica.subs() . THANKS

• How to signal a buffer full state between posix threads

  - by mikip

  Hi I have two threads, the main thread 'A' is responsible for message handling between a number of processes. When thread A gets a buffer full message, it should inform thread B and pass a pointer to the buffer which thread B will then process. When thread B has finished it should inform thread A that it has finished. How do I go about implementing this using posix threads using C on linux. I have looked at conditional variables, is this the way to go? . I'm not experienced in multi threaded programming and would like some advice on the best avenue to take. Thanks

• Implementing callback functions in C

  - by robertjohn123

  Hi, I am a newbie to C.I am trying to implement callback function using function pointers. I am getting an error :test_callback.c:10: error: expected identifier or ‘(’ before ‘void’ when I try to compile the following program: #include<stdio.h> void (*callback) (void); void callback_proc () { printf ("Inside callback funtion\n"); } void register ((void (*callback) (void))) { printf ("Inside registration \n"); callback (); /* Calling an initial callback with function pointer */ } int main () { callback = callback_proc;/* Assigning function to the function pointer */ register (callback);/* Passing the function pointer */ return 0; } What is this error?Can anyone help?

• How to preserve object identity across different VMs

  - by wheleph

  To be specific let me illustrate the question with Spring http-remoting example. Suppose we have such implementation of a simple interface: public SearchServiceImpl implements SearchService { public SearchJdo processSearch(SearchJdo search) { search.name = "a funky name"; return search; } } SearchJdo is itself a simple POJO. Now when we call the method from a client through http-remoting we'll get: public class HTTPClient { public static void main(final String[] arguments) { final ApplicationContext context = new ClassPathXmlApplicationContext( "spring-http-client-config.xml"); final SearchService searchService = (SearchService) context.getBean("searchService"); SearchJdo search = new SearchJdo(); search.name = "myName"; // this method actually returns the same object it gets as an argument SearchJdo search2 = searchService.processSearch(search); System.out.println(search == search2); // prints "false" } } The problem is that the search objects are different because of serializaton although from logical prospective they are the same. The question is whether there are some technique that allows to support or emulate object identity across VMs.

• An Actor "queue" ?

  - by synic

  In Java, to write a library that makes requests to a server, I usually implement some sort of dispatcher (not unlike the one found here in the Twitter4J library: http://github.com/yusuke/twitter4j/blob/master/twitter4j-core/src/main/java/twitter4j/internal/async/DispatcherImpl.java) to limit the number of connections, to perform asynchronous tasks, etc. The idea is that N number of threads are created. A "Task" is queued and all threads are notified, and one of the threads, when it's ready, will pop an item from the queue, do the work, and then return to a waiting state. If all the threads are busy working on a Task, then the Task is just queued, and the next available thread will take it. This keeps the max number of connections to N, and allows at most N Tasks to be operating at the same time. I'm wondering what kind of system I can create with Actors that will accomplish the same thing? Is there a way to have N number of Actors, and when a new message is ready, pass it off to an Actor to handle it - and if all Actors are busy, just queue the message?

• Adding a imageview to child elements in a expandable list query

  - by Thomas Millin

  I am looking to find out how to assign an image to a imageview in each child of an expandable list. If anyone has any information or links to find out how to do this I would be most appreciative. expListAdapter = new SimpleExpandableListAdapter( main.this, createGroupList(), R.layout.parentnode, new String[] { "day", "number" }, new int[] { R.id.TextView01, R.id.TextView02 }, createChildList(), R.layout.child_row, new String[] { "image", "childName", "date"}, new int[] { R.id.ImageView01, R.id.childname, R.id.date } ); setListAdapter( expListAdapter ); is what my adapter looks like at the moment, I have very little experience in customising adapters so I do not know where to start. Any help would be great :D

• Sorting data by relevance, from multiple tables

  - by Oden

  Hey, How is it possible to sort data from multiple tables by relevance? My table structure is following: I have 3 tables in my database, one table contains the name of solar systems, the second for e.g. of planets. There is one more table, witch is a connection between solar systems and planets. If I want to get data of a planet, witch is in the Milky Way, i post this data to the server, and it gives me a multi-dimensional array witch contains: The Milky Way, with every planet in it Every planet, witch name contains the string Milky Way (maybe thats a bat example because i don't think that theres but one planet with this name, but the main concept is on file) But, i want to set the most relevant restaurants to the top of the array. (for the relevance i would check the description of the restaurants or something like that) So, how would you do that kind of data sorting?

• Remove all references to a DLL across all application domains

  - by ck

  I have a web application that dynamically loads assemblies based on database configuration entries to perform certain actions (dynamic plugin style architecture). The calls to the objects are in a Factory Pattern implementation, and the object is cached (in a static dictionary< within the Factory) as the calls can be made many thousands of times in a minute. The calls to this factory are made from both the main web application and a number of webservices, some in different assemblies/projects. When I need to update one of these DLLs, I have to recycle IIS to get the DLL released. As this has an impact on another application on the server, I wanted to know if there was a way I could release the DLL without restarting IIS?

• Abstract classes in shared library

  - by JTom

  Hi, I have an ordinary abstract class that has couple of pure virtual methods. The class itself is a part of the shared library. The compilation of the shared library itself is OK. But when the library is linked to another program that has another class deriving from the abstract one in the shared library and defining the pure virtual methods, I get the following linker error: I compile like this..: g++ -I../path/to/the/library main.cpp derived.cpp -L../path/to/the/library -lsomename -o shared ...and the linker error is: libsomename.so: undefined reference to `AbstractClass::method()' It's like the abstract class cannot access its pure virtual methods but I do not try to make any instance of the abstract class anywhere in the library. What could be the problem?

• Git Submodule or fork

  - by Eric

  I have a private repo in github that is the complete source code to my cms. Now I have a few local customers that I want to use the same code base on but with different themes. Is it better to fork the original project out into a repo for each one. Or use a submodule and create a new repo for each customer? After each site is complete I would imagine the theme files wouldn't change much but would need to pull in changes from the main repo when bugs are discovered.

• Tabcompletion and docview while editing rc.lua

  - by Berxue

  I saw that there is a lua plugin for eclipse and there is a docpage on the awesome main page api_doc and all the .lua files in /usr/share/awesome/lib. So I thought it must be possible to create a Library or Execution Environment so that one has tabcompletion and docview. So I tried making my own Execution Environment: wrote the standard .rockspec file downloaded the documentation made an ofline version of it and put it in docs/ folder ziped the files and folders in /usr/share/awesome/lib ziped all up tried it out ... and it failed. When I try to view a documentaion for a .lua file I get "Note: This element has no attached documentation." Questions: Am I totaly wrong in my doing (because I have the feeling I am)? Is there any way to edit the rc.lua with tabcompletion and docview?

• Is there a more efficient way to retrieve tables from websites using wpf + webclient

  - by Jordan Brooker

  new to the community, but here is my first question that I am stuck on. I am new to WPF and WebClient using c# and I am attempting to make a program that access www.nba.com to populate a combobox I have with team names, and then when a user selects a team from the combobox, I wanted to populate a portion of the main window with the roster from the teams home site, same style and eveything. I was able to populate the combobox using the WebClient.OpenRead and reading in the markup to extract the team names. Now I am on the more difficult part. I was planning on using the same method to grab all the markup and then somehow display the table in a content panel, but I feel that this is a very tedious thing to do. Can anyone give me any tips for completing this action or is there a method in the webclient class that allows me to search a webpage for a table or object other than text? Thanks.

• How do I define an implicit typecast from my class to a scalar?

  - by Delan Azabani

  I have the following code, which uses a Unicode string class from a library that I'm writing: #include <cstdio> #include "ucpp" main() { ustring a = "test"; ustring b = "ing"; ustring c = "- -"; ustring d; d = "cafe\xcc\x81"; printf("%s\n", (a + b + c[1] + d).encode()); } The encode method of the ustring class instances converts the internal Unicode into a UTF-8 char *. However, because I don't have access to the char class definition, I am unsure on how I can define an implicit typecast (so that I don't have to manually call encode when using with printf, etc).

• How can I access and change elements in this private readonly property?

  - by CrimsonX

  I'm trying to figure out how I am able to successfully change a "readonly" array. I have this: namespace ConsoleApplication1 { class Program { static void Main(string[] args) { MyClass myClass = new MyClass(); myClass.Time[5] = 5; // How is this legal? } } public class MyClass { private readonly uint[] time; public IList<uint> Time { get { return time; } } public MyClass() { time = new uint[7]; } } } As I Note above, I would expect that Time[5] would be illegal due to the fact that public IList Time does not have a setter. Additionally, how can I create an array in the constructor which is read-only and unchangeable outside of this class?

• WinForms / .Net interactive world map - how?

  - by FerretallicA

  In a CD collection program, I have each artist's country of origin stored in the main database and want to display a map of the world which: Colour-codes each country depending on the number of CDs by artists in that country Allows clicking on each country to filter a list of CDs to only ones by artists in that country This is a heavily simplified version of what I'm trying to do, but if I can at least get this far the rest should be easy enough to figure out. So far the closest thing I've found to what I'm trying to do is here: http://www.synergetechsolutions.com/blog/analytics-world-map-control Ideally I don't want to be embedding Flash in my program though, and the only other solutions I've found all involve SVG which I haven't managed to get working in practice outside of a web browser control (and I DEFINITELY don't want to be embedding a browser in the forms). Something in pure managed code and either GDI+ or WPF would be preferable. Are there any existing components that would get me started, or can anyone suggest how to approach it from scratch?

• Eclipse debugging "source not found"

  - by James

  I just started using Eclipse so go easy on me ;). But when trying to debug a JUnit test case I get a dialog that states the the source is not found when I get to this line in the code in my test method: Assert.assertEquals(1, contents.size()); I know I should probably go and try and download the source from somewhere, but I really don't want to because I have no interest in stepping into the JUnit code. I have the JUnit runtime jar so Why does Eclipse expect me to have all the referenced tools source code in order to debug my own code (seems somewhat silly)? My main question is though, how can I tell Eclipse to skip this dialog when the source is not available and allow me to continue to debug my own code? [Edit] I've isolated the cause of this. It seems that Eclipse seems to think it needs the source when an exception is thrown by the internal JUnit code. In general is there anyway to tell it that it doesn't and just have it throw up an error dialog of some kind instead?
