  • Alternatives to nested interfaces (not possible in C#)

    - by ericdes
    I'm using interfaces in this case mostly as a handle to an immutable instance of an object. The problem is that nested interfaces in C# are not allowed. Here is the code: public interface ICountry { ICountryInfo Info { get; } // Nested interface results in error message: // Error 13 'ICountryInfo': interfaces cannot declare types public interface ICountryInfo { int Population { get; } string Note { get; } } } public class Country : ICountry { CountryInfo Info { get; set; } public class CountryInfo : ICountry.ICountryInfo { int Population { get; set; } string Note { get; set; } ..... } ..... } I'm looking for an alternative, anybody would have a solution?

  • How to clear the memory allocated for Customized Exception

    - by ilan
    Hi All I have a customized exception class. say class CustomExcep{}; My Application is a middleware made of C++. It is a webservice which is used for the communication between Java based web Front-end and the DCE Backend. whenever the DCE Backend is not running or down due to some core dumps, the application throws the CustomExcep. It's like this. CustomExcep * exc = new CustomExcep(); throw exc; I am unable to use the stack memory for this as it leads to some run-time exceptions. I need a solution to clear the memory used by this CustomException. Can we use Templates for this purpose? Any help would be appreciated. Thanks in Advance.

  • Twisted - how to create multi protocol process and send the data between the protocols

    - by SpankMe
    Hey, Im trying to write a program that would be listening for data (simple text messages) on some port (say tcp 6666) and then pass them to one or more different protocols - irc, xmpp and so on. I've tried many approaches and digged the Internet, but I cant find easy and working solution for such task. The code I am currently fighting with is here: http://pastebin.com/ri7caXih I would like to know how to from object like: ircf = ircFactory('asdfasdf', '#asdf666') get access to self protocol methods, because this: self.protocol.dupa1(msg) returns error about self not being passed to active protocol object. Or maybe there is other, better, easier and more kosher way to create single reactor with multiple protocols and have actions triggeres when a message arrives on any of them, and then pass that message to other protocols for handling/processing/sending? Any help will be highly appreciated!

  • Build an unbound form in Acess 2007

    - by DoubleJ92
    I have an access application that has a form that allows the user to enter case notes. The main field of this form is tied to a SQL Server varchar(MAX) field in the source table. Since the users switched to Access 2007, their program keeps crashing when they are on the case notes form. As a possible solution to this problem, I would like to try unbinding this form and re-building it as an unbound form. This form needs to be able to add and update records into my SQL Server database. It also needs to be able to browse between records. I guess I am at a loss as to where to start. Any suggestions/code snippets is appreciated.

  • Storing uploaded content on a website

    - by Matt
    For the past 5 years, my typical solution for storing uploaded files (images, videos, documents, etc) was to throw everything into an "upload" folder and give it a unique name. I'm looking to refine my methods for storing uploaded content and I'm just wondering what other methods are used / preferred. I've considered storing each item in their own folder (folder name is the Id in the db) so I can preserve the uploaded file name. I've also considered uploading all media to a locked folder, then using a file handler, which you pass the Id of the file you want to download in the querystring, it would then read the file and send the bytes to the user. This is handy for checking access, and restricting bandwidth for users.

  • How to use client side code in Visual studio ASP.NET

    - by Robert
    I am a quite new to web development and I am trying to do some small form updates without causing a postback. For example making a control visible when a drop down list is changed. I have so far come across some features that achieve this like the RequiredFieldValidator inside an update panels. However, these are specific to a single task. What are my options to achieve these client side updates in Visual Studio? At the moment I don't know any JavaScript, so I would prefer another solution if it exists.

  • jQuery: How to fire event when all asynchronous calls return?

    - by Jeremy
    I have a jQuery application that loads data from five asynchronous server calls. I do not want to display any data until all five calls return. (I plan on displaying a Loading message until that happens.) How can I detect when all five calls have returned? I considered having each callback method increment a variable (using jQuery's data() method, perhaps) and then waiting for the value to become 5. (I am not sure yet how I would listen for that event.) I do not think this is a very good solution, however. What would happen if two calls return at the same time? Is there a better way to do this?

  • JSF - Session Bean restart on logout and login

    - by Ben
    Hi, I have a web application with a backing bean which has the context of the current logged in user. It is implemented on JSF. When the user logs out he is forwarded to a login screen (in another JSP page). I would like the current session to be erased when that happens and a new one to be created the next time the user logs in and enters the application. My question is - how do you delete a session? (I guess the new session will be created automatically the next time the user enters the link) This is kinda newb i guess, but I couldn't find a solution for this. Thanks for the Help!

  • Syncing with Address Book: Last modified property in ABPerson/ABRecord

    - by Oliver
    I'm syncing data from the Address Book into a Core Data database and I've nearly got it working perfectly. The only issue remaining is checking for changes and modifications on startup and reflecting the changes inside Core Data. Currently, I simply check the ID of each ABRecord and see if it is already in Core Data. Of course, this only works in the case of new contacts and not changed information inside an existing contact. One solution would be to go through each contact already in the database and check each property against the Address Book. The down side of this is that it's really slow. One method that would work is if the ABRecord had a last modified date. I could then store the date inside the Core Data database and check on startup to see if I need to update the contact. However, I can't find anything like this in the documentation. Any ideas?

  • UIWebview: Dynamically adding html content

    - by user739711
    I am making an app in which I get text from my server and display it in UIWebview. After some time more text is added and client(iphone) is notified about the additional-text. Now I want to inject this text into my UIWebview. Anybody know how to do it? One method is to update some text file and reload the content. But I dont want to reload the page. Another way can be to use javascript to check updates in a local file (which seems better). Is there any known better solution?

  • Git Status Across Multiple Repositories on a Mac

    - by eapen
    I have been searching for a solution to this for a while and have not found quite what I need. I have several Git Repositories in a folder on my Mac (OSX 10.6) and would like a script or tool that will loop through all the repositories and let me know if any of them needs "commit"-ing. This is my structure Sites   /project1   /project2   /project3 I want the tool to do a "git status" in Sites/project1, Sites/project2, Sites/project3 and let me know if Sites/project2 and Sites/project3 have changes or new files and needs to be Staged/committed The closest script I found that might be hackable is here: http://gist.github.com/371828 but even that script wouldn't run and I get an error: "syntax error near unexpected token `do" which might have been written for *nix.

  • Could Grand Central Dispatch (`libdispatch`) ever be made available on Windows?

    - by elliottcable
    I’m looking into multithreading, and GCD seems like a much better option than manually writing a solution using pthread.h and pthreads-win32. However, although it looks like libdispatch is either working on, or soon going to be working on, most newer POSIX-compatible systems… I have to ask, what about Windows? What are the chances of libdispatch being ported to Windows? What are the barriers preventing that from happening? If it came down to it, what would I need to do to preform that portage? Edit: Some things I already know, to get the discussion started: We need a blocks-compatible compiler that will compile on Windows, no? Will PLBlocks handle that? Can we use the LLVM blocks runtime? Can’t we replace all the pthread.h dependencies in userspace libdispatch with APR calls, for portability? Or, alternatively, use pthreads-win32 I suppose…

  • Better exception for non-exhaustive patterns in case

    - by toofarsideways
    Is there a way to get GHCi to produce better exception messages when it finds at runtime that a call has produced value that does not match the function's pattern matching? It currently gives the line numbers of the function which produced the non-exhaustive pattern match which though helpful at times does require a round of debugging which at times I feel is doing the same set of things over and over. So before I tried to put together a solution I wanted to see if something else exists. An exception message that in addition to giving the line numbers shows what kind of call it attempted to make? Is this even possible?

  • Python: Get items at depth? (set library?)

    - by Mark
    I have a nested list something like this: PLACES = ( ('CA', 'Canada', ( ('AB', 'Alberta'), ('BC', 'British Columbia' ( ('van', 'Vancouver'), ), ... )), ('US', 'United States', ( ('AL', 'Alabama'), ('AK', 'Alaska'), ... I need to retrieve some data out of it. If depth is 0 I need to retrieve all the countries (and their codes), if depth == 1, I need to retrieve all the states/provinces, if depth == 2 I need to retrieve all the cities... and so forth. Is there some set library for doing stuff like this? Or can someone point me in the right direction? I started coding up a solution only to realize it wouldn't work for levels deeper than 1 because you have to go in and out of each list...

  • How to unmangle exported symbols from C++ in dynamic libraries in XCode on OSX

    - by Gerald
    I've been trying to develop a dynamic library in C++ that can be run-time loaded in an application. I finally got it working, but it's a little ugly. I have a function that takes a pointer to a C++ class as an argument, which looks like this: bool registerGrindPlugin( Grind::PluginManager* mgr ); But of course it's being exported as: _Z19registerGrindPluginPN5Grind13PluginManagerE I tried a .c file with a simple function and it exported fine as "registerGrindPlugin", but of course I can't pass a C++ class as the argument that way. Soo... my question is, is there a way to unmangle or alias the exported symbol so that I don't have to use a monstrosity like Z19registerGrindPluginPN5Grind13PluginManagerE in my dlsym call? I did see something about -alias_list as a linker option, but I haven't quite figured out how to use it in XCode. If that is the solution, can somebody provide some more details on how to use this?

  • Debugging of native code

    - by graham.reeds
    I have a C# Service that is calling a C DLL that was originally written in VC6. There is a bug in the DLL which I am trying to inspect. After having a nightmare trying to get debug to work I eventually added the dll to the VS2005 solution containing the C# Service and added the necessary _CRT_SECURE_NO_WARNINGS. The debug version of the service is registered using 'installutil.exe' tool. I can get the debugger to break just before the line where the dll is entered via a call to System.Diagnostics.Debugger.Break();. I found some instruction on the net regarding stepping into debugging unmanaged code, and enabled the 'Enable unmanaged code debugging' check box, I've also tried turning on the Options-Debugging-Native 'Load DLL exports' and 'Enable RPC Debugging' (even though it's not COM). I've also copied the debug dll and .pdb to the same bin directory as the However the unmanaged code is not being stepped into which is what I really need. UPDATE: I found the Debugging Type in the DLL properties and set it to 'Mixed' as per suggestion on several sites but to no avail.

  • Libraries/Solutions for using XSL to create interactive web forms from XML

    - by Brabster
    This seems like a pretty straightforward thing to do, but I can't find anything off the open-source shelf. Is there a solution already out there that does the following: can be configured with an arbitrary XSL stylesheet generates a web form based on an arbitrary XML document and the XSL creates edit functionality in appropriate places in the rendered form updates the local representation of the XML document provides capabilities to view, save the new XML document Ideally, one that plugs into a Java web application. Even better if it can generate the XSL based on schema documents - but that might not be feasible, not really thought it through. For context, I'm thinking things like pleasant-for-humans editing of Maven POMs, ANT build.xml, etc. Cheers,

  • php - Can I integrate functions with same content, different names?

    - by Gal
    I have a couple of functions inside a class that essentially do the same thing: public function fn_a(){ return __FUNCTION__; } public function fn_b(){ return __FUNCTION__; } public function fn_c(){ return __FUNCTION__; } I need those functions to remain in their current names so I intentionally did not do: public function fn_($letter){ return __FUNCTION__.$letter; } I was hoping for some sort of way to minify the verboseness of code here, since they all do the same. The ultimate situation would be something like this: public functions fn_a, fn_b, fn_c() { return __FUNCTION__; } Another solution, if applicable, might be doing something like Class's "extends": fn_b, fn_c extend fn_a? What do you think guys?

  • How do I record streams in chunks on Flash Media Server.

    - by Vasil
    I want to record a stream which is published with Flash Live Encoder to FMS 3.5, but split the recording in files with predefined length. For example if a stream 'webcam' is published I want to record it in chunks of 10 minutes: 'webcam1.flv', 'webcam2.flv' ... From what I can tell there's no facility to work with timers. The only solution I could think of was using stream.record() with a time limit parameter but that seems like a hack because it triggers NetStream.Record.DiskQuotaExceeded on the stream when the recordin should stop and start recording another chunk. Has anyone done something similar?

  • How to define a multipage environment not interrupted by tables and figures?

    - by Egon Willighagen
    I have defined a new LaTeX environment for excursions in a book chapter I am writing. The environment is multipage and often includes inline images. Moreover, I am using the shaded environment to give the environment a background colour to make it stand out a bit. However, the environment, as shown below, is split up by floating tables and images, which makes the flow of the environment visually more difficult to follow. For example, it is now difficult to see if that floating image or table is part (the missing background colour does not help). So, I like to extend my environment to disallow it to be interrupted by floating elements, but do not know how to get that done. \newcounter{bioclipse} \def\thebioclipse{\thechapter-\arabic{bioclipse}} \newenvironment{bioclipse}[2][]{\begin{small}\begin{shaded}\refstepcounter{bioclipse} \par\medskip\noindent% \textbf{Bioclipse Excursion~\thebioclipse #1: #2 \vspace{0.1cm} \hrule \vspace{0.1cm}} \rmfamily}{\medskip \end{shaded}\end{small}} Any solution to disallow interruption is fine, even if the background colour is done differently.

  • Update tableview instantly as data pushed in core data iphone

    - by user336685
    I need to update the tableview as soon as the content is pushed in core data database. for this AppDelegate.m contains following code NSManagedObjectContext *moc = [self managedObjectContext]; NSFetchRequest *request = [[NSFetchRequest alloc] init]; [request setEntity:[NSEntityDescription entityForName:@"FeedItem" inManagedObjectContext:moc]]; //for loop // push data in code data & then save context [moc save:&error]; ZAssert(error == nil, @"Error saving context: %@", [error localizedDescription]); //for loop ends This code triggers following code from RootviewController.m - (void)controllerWillChangeContent:(NSFetchedResultsController*)controller { [[self tableView] beginUpdates]; } But this updates the tableview only at the end of the for loop ,the table does not get updated after immediate push in db. I tried following code but that didn't work - (void)controllerDidChangeContent:(NSFetchedResultsController *)controller { // In the simplest, most efficient, case, reload the table view. [self.tableView reloadData]; } I have been stuck with this problem for several days.Please help.Thanks in advance for solution.

  • What adapter to use for ExpandableListView with non-TextView views?

    - by David
    I have an ExpandableListView in which I'd like to have controls other than TextView. Apparently, SimpleExandableListViewAdapter assumes all the controls are TextViews. A cast exception is generated if they are not. What is the recommended solution? Options I can think of include: - Use some other included adapter. But I can't tell if they all have the same assumption. - Create my own adapter. Is there a doc which describes the contract, ie the sequence of method calls an adapter will encounter? I expected the existing adapters to require the views to conform to some interface to allow any conforming view to be used, rather than hardcode to textview and limit where they can be used.

  • Private JQuery instance

    - by Nir Levy
    We are writing a SaaS like solution that requires our customers to SCRIPT SRC some javascript code we are building (think Google Analytics scenario). We would like to use JQuery. However, since our customers might already have conflicting JQuery versions or other conflicting frameworks (prototype.js for one) we cannot tell them to source jquery.js. We were thinking of coping the jquery source as to create a 'private' jquery instance and simple search/replace the JQuery and $ functions with myJQuery and $J Is there any reason for this not to work? has anyone tried something like this? What can we do about plugins?
