  • Return pointer to nested inner class from generic outer class

    - by helixed
    I'm new to C++, so bear with me. I have a generic class called A. A has a nested class called B. A contains a method called getB(), which is supposed to return a new instance of B. However, I can't get my code to compile. Here's what it looks like:#include A.h template <class E> class A { public: class B { public: int data; }; B * getB(); }; A.cpp #include "A.h" template <class E> A<E>::B * A::getB() { return new B(); } When I try to compile this, I get the following error: error: expected constructor, destructor, or type conversion before '*' token Does anybody know what I'm doing wrong? Thanks, helixed

  • Powerbuilder Dynamic Array Manipulation

    - by TomatoSandwich
    string array[] long lBound, uBound lBound = LowerBound(array[]) // = 1, empty array value uBound = UpperBound(array[]) // = 0, empty array value array[1] = 'Item 1' array[2] = 'Item 2' array[3] = 'Item 3' lBound = LowerBound(array[]) // = 1 uBound = UpperBound(array[]) // = 3 array[3] = '' //removing item 3 lBound = LowerBound(array[]) // = 1, still uBound = UpperBound(array[]) // = 3, still (but array[3] is nulled? I think the line 'array[3]' is wrong, but I think I've read that this should remove the array cell. What would be the right way to remove an array cell? Does it depend on object type? (String vs Number vs Object) Or Can one manipulate the UpperBound value to make it work? i.e. after removing Item 3, I want the UpperBound, or arraylength, to be 2, since this is logically correct.

  • Does OpenRasta support Mono?

    - by Earlz
    Although Mono support is not a big deal for us, I figured OpenRasta supported it cause it has some commit messages about it.. Well, I tried to build it on Mono and got Ambiguous type references(after manually creating like 10 obj directories.) So I tried just using the prebuilt assemblies I had on hand and that gave me an Object Reference Not Set To Instance of an Object (the usual error I have with mono.. ) at OpenRasta.Diagnostics.DebuggerLoggingTraceListener.WriteAll (using xsp2) Is there official support for Mono or am I missing some sorta extra step for deployment?

  • html hyperlinks show URL in brackets in Entourage

    - by Rafe
    I have an email script written in .Net that sends html emails. The email uses normal html hyperlinks to insert a link in the email, like this: <a href="http://www.stackoverflow.com/">StackOverflow</a> The problem is that in Entourage, a hyperlink like this always shows up for me like this: StackOverflow < http://www.stackoverflow.com/ > How can I format the hyperlink in my email so that in Entourage the text "StackOverflow" is the actual hyperlink, and the URL is not displayed after the text? Is there an html meta tag that needs to be set? Do I have to set the content-type somewhere? Or is there a different html syntax on the hyperlink itself that I should use?

  • Using memcache to store obj's in google app engine.

    - by fredrik
    Hi, I'm trying to use memcache to cache data retrevied from the datastore. Storing stings works fine. But can't one store an object? I get an error "TypeError: 'str' object is not callable" when trying to store with this: pageData = PageType(page) memcache.add(memcacheid, pageData, 60) I've read in the documentation that it requires "The value type can be any value supported by the Python pickle module for serializing values." But don't really understand what that is. Or how to convert pageData to it. Any ideas? ..fredrik

It looks like this: How do I get rid of it?

  • Are document-oriented databases meant to replace relational databases?

    - by evolve
    Recently I've been working a little with MongoDB and I have to say I really like it. However it is a completely different type of database then I am used. I've noticed that it is most definitely better for certain types of data, however for heavily normalized databases it might not be the best choice. It appears to me however that it can completely take the place of just about any relational database you may have and in most cases perform better, which is mind boggling. This leads me to ask a few questions: Are document-oriented databases have been developed to be the next generation of databases and basically replace relational databases completely? Is it possible that projects would be better off using both a document-oriented database and a relational database side by side for various data which is better suited for one or the other? If document-oriented databases are not meant to replace relational databases, then does anyone have an example of a database structure which would absolutely be better off in a relational database (or vice-versa)?

  • android: using listpreference and retrieving key string...

    - by Allan
    I have a settings menu that pops up and in it is a listpreference type menu. It is associated with a settings.xml file where there are 'array-strings' within it. It all works good but I don't know how to retrieve the users preference. As an example, let's say the user picks a color (red, green, or blue). The list that I've made within my 'array-strings' contain the text red, green, and blue. Within my code, I would like to do something if the user has choosen red, something else if they choose blue, etc., etc. Would I use a 'case' statement or an 'if' statement? And most importantly, how would I retrieve the users preference - the key? (am I checking for a boolean?) Help would be appreciated...thank you...

  • Redirect console input and output to a textbox.

    - by Peter
    Hi there and thanking in advance I am trying (very hard) to redirect Console input and output into a textbox. So far output is working fine but the trouble is with input. For example I cannot execute a simple program that will do the following: Console.WriteLine("Please enter your name: "); string name = Console.ReadLine(); Console.WriteLine("Hi there " + name); The reason I can't achieve this is because that the program has to stop while waiting for user to type his/her name and press enter. If I wait for user input on a new thread then the main GUI thread freezes and the textbox can never receive the KeyPress. This thing has me totally stumped. Any advice (or better still code) would be greatly appreciated. Cheers

  • functional-style datatypes in Python

    - by Danny Roberts
    For anyone who's spent some time with sml, ocaml, haskell, etc. when you go back to using C, Python, Java, etc. you start to notice things you never knew were missing. I'm doing some stuff in Python and I realized what I really want is a functional-style datatype like (for example) datatype phoneme = Vowel of string | Consonant of voice * place * manner datatype voice = Voiced | Voiceless datatype place = Labial | Dental | Retroflex | Palatal | Velar | Glottal datatype manner = Stop | Affricate | Fricative | Nasal | Lateral type syllable = phoneme list Does anyone have a particular way that they like to simulate this in Python?

  • Python 3 with the range function

    - by Leif Andersen
    I can type in the following code in the terminal, and it works: for i in range(5): print(i) And it will print: 0 1 2 3 4 as expected. However, I tried to write a script that does a similar thing: print(current_chunk.data) read_chunk(file, current_chunk) numVerts, numFaces, numEdges = current_chunk.data print(current_chunk.data) print(numVerts) for vertex in range(numVerts): print("Hello World") current_chunk.data is gained from the following method: def read_chunk(file, chunk): line = file.readline() while line.startswith('#'): line = file.readline() chunk.data = line.split() The output for this is: ['OFF'] ['490', '518', '0'] 490 Traceback (most recent call last): File "/home/leif/src/install/linux2/.blender/scripts/io/import_scene_off.py", line 88, in execute load_off(self.properties.path, context) File "/home/leif/src/install/linux2/.blender/scripts/io/import_scene_off.py", line 68, in load_off for vertex in range(numVerts): TypeError: 'str' object cannot be interpreted as an integer So, why isn't it spitting out Hello World 490 times? Or is the 490 being thought of as a string? I opened the file like this: def load_off(filename, context): file = open(filename, 'r')

  • How to callback the new list id jQuery UI: sortable

    - by PARyGuy
    Hi, I'm trying to use the sortable widget for my site. I have a mini scheduling app that I'd like to display a list of appointments for the week sorted by days. For this example we'll use only two days ( 2 lists ). If I wanted to drag an appointment (list item) from day 2 over to day 1, is there a way I can callback the id of list 1 after I dragged an item to it? I can find the id of the parent list upon page load but I can't seem to be able to pull the new id after sort. Is this even possible? <script type="text/javascript"> $(function() { $("#day1, #day2").sortable({ connectWith: '.sortable' }).disableSelection(); }); </script>

  • Visual studio 2010 MVC 2 (2008 project imported) - publish fails - System.Web.Routing.RouteValueDict

    - by Maslow
    Error 7 The type 'System.Web.Routing.RouteValueDictionary' exists in both 'c:\Program Files\Reference Assemblies\Microsoft\Framework\.NETFramework\v4.0\System.Web.dll' and 'c:\WINNT\assembly\GAC_MSIL\System.Web.Routing\3.5.0.0__31bf3856ad364e35\System.Web.Routing.dll' c:\Projects\VS\solutionfolder\projectfolder\Views\group\List.aspx 44 ProjectName The project utilizes T4MVC.tt if that is relevant. Also Visual studio 2010 ultimate. I did not upgrade the target .net framework to 4.0 because my host will not support this for ~24 hours. I have a .Tests project in the same solution that says it is targeting .net 4.0 but it still won't build even with that unloaded, same message.

  • .DBML file and LINQ to SQL

    - by Rishabh Ohri
    In my DBML file I have mapped some tables and stored procedures, and the stored procedures return type is ISingleResult . T is some mapped table. But I want to take the data into my own created entities rather than LINQ to SQL created entites. The entites created by me are also the same as the mapped table entities and their use lies when we send data across the a web service. So , how can I proceed by creating a wrapper around the DBML file so that I always get data in my own created entites.

  • Scala: How to combine parser combinators from different objects

    - by eed3si9n
    Given a family of objects that implement parser combinators, how do I combine the parsers? Since Parsers.Parser is an inner class, and in Scala inner classes are bound to the outer object, the story becomes slightly complicated. Here's an example that attempts to combine two parsers from different objects. import scala.util.parsing.combinator._ class BinaryParser extends JavaTokenParsers { def anyrep: Parser[Any] = rep(any) def any: Parser[Any] = zero | one def zero: Parser[Any] = "0" def one: Parser[Any] = "1" } object LongChainParser extends BinaryParser { def parser1: Parser[Any] = zero~zero~one~one } object ShortChainParser extends BinaryParser { def parser2: Parser[Any] = zero~zero } object ExampleParser extends BinaryParser { def parser: Parser[Any] = (LongChainParser.parser1 ||| ShortChainParser.parser2) ~ anyrep def main(args: Array[String]) { println(parseAll(parser, args(0) )) } } This results to the following error: <console>:11: error: type mismatch; found : ShortChainParser.Parser[Any] required: LongChainParser.Parser[?] def parser: Parser[Any] = (LongChainParser.parser1 ||| ShortChainParser.parser2) ~ anyrep I've found the solution to this problem already, but since it was brought up recently on scala-user ML (Problem injecting one parser into another), it's probably worth putting it here too.

  • How can I prompt user for additional permissions on page load?

    - by Rew
    Note: The application I'm building is a website type Facebook Application that uses Facebook Connect. I can prompt the user with a request for Extended Permissions using the following FBML code: <fb:prompt-permission perms="read_stream,publish_stream"> Grant permission for status updates </fb:prompt-permission> Taken from here. This creates a link on the page that must be clicked by the user in order to trigger the prompt to display. My question is: Is it possible to display this prompt automatically, when the page loads, without requiring the user to click on the link? Also, in reply to the answer below, I'd like to avoid displaying the link. Would prefer a neat way to do this, if that fails the least dirty method will do :-)
