• Create an own "OpenID-like system" Provider

  - by user502052

  I know that Facebook use their own OpenID-like system called "Facebook connect", which you can use to authenticate users on your site, among other features. In my case I have multiple Ruby on Rails applications: users.example.com profiles.example.com photos.example.com ... I would like to use 'users.example.com' as a web service that allows users to authenticate to all my other applications the same way as works "Facebook connect" or OpenID. In few words, 'users.example.com' must works as a "OpenID-like system" for my applications in 'example.com'. Can anyone give me tips and links to some useful resources? P.S.: since I am a newbie in this matter, I do not know if I'm saying things that make sense. So someone could help me to understand (if I am wrong) ...

• How to prevent autoplay and run my own app when inserting an USB-Flash drive

  - by Thomas

  when inserting an USB-Flash drive, Windows normally opens the Autoplay dialog that offers to browse the drive or if there are multimedia files it offers to choose an app to open them. We developed a media player that is connected to the USB-Drive and registers itself as Mass Storage Device. What I need is, that when inserting the Player that this Dialog is not shown, but instead my own application is launched. Ideally the application would be on the Flash Drive itself, but as I understood is that Autorun is disabled for USB-Drives. It would be enough if a preinstalled application is launched. I already tried to catch the WM_DRIVE_CHANGE message, but this only works if my application is the top most window, otherwise the Autoplay Dialog is displayed. Best Tom

• How to roll my own index in c#?

  - by bill seacham

  I need a faster way to create an index file. The application generates pairs of items to be indexed. I currently add each pair as it is generated to a sorted dictionary and then write it out to a disk file. This works well until the number of items added exceeds one million, at which time it slows to the point that is unacceptable. There can be as many as three million data items to be indexed. I prefer to avoid a database because I do not want to significantly increase the size of the deployment package, which is now less than one-half of one megabyte. I tried Access but it is even slower than the sorted dictionary -if it had an efficient bulk load utility then that might work, but I do not find such a tool for Access. Is there a better way to roll my own index?

• Making your own "int" or "string" class

  - by amerninja13

  I disassembled the .NET 'System' DLL and looked at the source code for the variable classes (string, int, byte, etc.) to see if I could figure out how to make a class that could take on a value. I noticed that the "Int32" class inherits the following: IComparable, IFormattable, IConvertible, IComparable, IEquatable. The String and Int32 classes are not inheritable, and I can't figure out what in these inherited interfaces allows the classes to hold a value. What I would want is something like this: public class MyVariable : //inherits here { //Code in here that allows it to get/set the value } public static class Main(string[] args) { MyVariable a = "This is my own custom variable!"; MyVariable b = 2976; if(a == "Hello") { } if(b = 10) { } Console.WriteLine(a.ToString()); Console.WriteLine(a.ToString()); }

• How to write own DLL in Visual Studio, C language (not C++)

  - by oneee

  Dear all, I'm trying to create my own DLL... I used wizzard in VS2008 to create template for DLL. This works fine and the dll builds successfully (Test.dll is created). BUT, when I rename the file from Test.cpp to Test.c (which I guess causes compilation in C-mode), solution rebuilds also successfully, but no .dll is created. The list of all created files follows: mt.dep BuildLog.htm vc90.idb Test.dll.embed.manifest Test.dll.intermediate.manifest Test.obj MySecondCFile.obj vc90.pdb Test.dll.embed.manifest.res For my purposes it's essential that the dll be in C not C++, while I already have a lot of code written in C, which does not compile as C++. Do you know, why .dll is not created? What should I do?

• jQuery code works in Firebug, but not on its own

  - by Ben

  I'm having quite the brainbuster of an issue right now. I am trying to change a link's hash tag at the end from "respond" to "comments" with jQuery. I have a simple script that should do this, however it does not work. The link does not change. However, Firebug shows no errors and when I run the code in Firebug's console, it works just as I intend. Why doesn't this work on its own? Does anybody have a solution, I'm at my wits edge with this one. (function ($) { $(document).ready(function() { $("a[href$='respond']").each(function() { $(this).attr("href", $(this).attr('href').replace("respond", "comments")); }); }); })(jQuery.noConflict()); Thanks so much, I know this might be a pain to test but I'm really thankful.

• Write-access for c# app in it's own exe dir in Windows 7

  - by fritz

  I know that user accounts in Windows 7 are limited by default, so a program cannot just write anywhere on the system (as it was possible in Win XP). But I thought that it would be possible that e.g. a c# app is allowed to write inside it's own exe-directory or it's subfolders at least (not everything is 'user settings' or should be written to "MyDocuments"...). So currently my c# app throws an UnauthorizedAccessException when trying to write inside the exe dir. Is there anything you can do in c# code to allow writing inside the exe dir?

• asp.net mvc model - my own database

  - by progtick

  The tutorials I have come across usually let you create a dababase from scratch creating a .mdf file or something and so on. However, what if I already have a SQL Server Express set up with the needed database? How do I tell my model to use that database? Right now, all my model contains is basically some classes that execute stored procedure on my own database and return manupulated data. Should I leave it as it is? What are the benefits of going through the full-fledged model approach that tutorials demonstrate?

• How do I best write my own background-working and communicatible (sending progress updates and getti

  - by Ivan

  I have to develop a class which can run it's own hard-coded task in a background thread and communicate with container class sending him progress updates and taking messages from it. I believe I am going to extend BackgroundWorker class but it looks a bit weird to extend and I haven't managed to find a good example wit Google. Can you share a link to a good example of solving such a task? Please don't offer placing a BackgroundWorker visually on a form and reading the standard tutorial, it's not for my case. Maybe I'd better not extend but encapsulate a BackgroundWorker, but I hardly understand how to use it outide WinForms designer either :-(

• Should every class have its own namespace?

  - by thehouse

  Something that has been troubling me for a while: The current wisdom is that types should be kept in a namespace that only contains functions which are part of the type's non-member interface (see C++ Coding Standards Sutter and Alexandrescu or here) to prevent ADL pulling in unrelated definitions. Does this imply that all classes must have a namespace of their own? If we assume that a class may be augmented in the future by the addition of non-member functions, then it can never be safe to put two types in the same namespace as either one of them may introduce non-member functions that could interfere with the other. The reason I ask is that namespaces are becoming cumbersome for me. I'm writing a header-only library and I find myself using classes names such as project::component::class_name::class_name. Their implementations call helper functions but as these can't be in the same namespace they also have to be fully qualified!

• Own params to PeriodicTask run() method in Celery

  - by Alex Isayko

  Hello to all! I am writing a small Django application and I should be able to create for each model object its periodical task which will be executed with a certain interval. I'm use for this a Celery application, but i can't understand one thing: class ProcessQueryTask(PeriodicTask): run_every = timedelta(minutes=1) def run(self, query_task_pk, **kwargs): logging.info('Process celery task for QueryTask %d' % query_task_pk) task = QueryTask.objects.get(pk=query_task_pk) task.exec_task() return True Then i'm do following: >>> from tasks.tasks import ProcessQueryTask >>> result1 = ProcessQueryTask.delay(query_task_pk=1) >>> result2 = ProcessQueryTask.delay(query_task_pk=2) First call is success, but other periodical calls returning the error - TypeError: run() takes exactly 2 non-keyword arguments (1 given) in celeryd server. So, can i pass own params to PeriodicTask run() ? Thanks!

• replace asp.net Response.Output with my own content

  - by WebDude

  I am trying to intercept a asp.net web request and based on a lookup replace the page thats going to be rendered to the client. example: is a request for "/about-us" comes to my web server, i will first see if i have a version of this in the database, otherwise i will revert to flat files. The version i will retrieve from the database will be a .aspx page that has to be rendered and containt web controls and inline serverside script. What is the best way to go about this? I have tried overriding the CreateHtmlTextWriter method but this seems too late in the process as the TextWriter passed to this method is already instantiated. I have also tried to Implement my own PageHandlerFactory but this seems to create an instance of Page of which i cannot seem to override its internal setting of the Response.Output stream. Amd i barking up the wrong tree here? what is the best approach to take here?

• I want to make my own Malloc

  - by Unknown

  I want to make my own malloc/free so I can make a precise copying allocator. Any gurus have any tips and suggestions? I have a few questions for now: Should I just malloc large chunks of memory, and then distribute from that so I don't have to call the system calls? How are copying collectors usually done? I would imagine that this part is a bit complicated to do efficiently. My naive implementation would just malloc a block the size of the remaining objects which would require 2x the space.

• Sending an anonymous email to my own address

  - by N3HL

  I want to send an anonymous email to my own gmail/hotmail/yahoo/any other mail service address (Im not trying to spam or something like that). Why? I have a .NET application and I want to add a "Send log to the developer" feature (attaching the log) using SmtpClient. The fact is I've read like 30+ pages, and found out, i.e. gmail's smtp client doesn't allow anonymous connections, and many other things. The idea is to receive a mail message like this: From: [email protected] (non-existent email really) To: [email protected] (this would be my real address which will recieve the logs attachments) Subject: Issue report nºX (auto-generated) Body: From a textbox Attachments: logs attached Is this possible? If so, how do I achieve it?

When the user clicks and holds on a text box whether it is a website or a piece of software a menu is displayed which shows paste and input method. What I want to be able to do is add my own items to this menu and when the user clicks on my item it will load my app, they can select an item from a list view. It will then copy the contents and automatically paste it into the text field the user selected. Thanks for your help in this matter

• Python: Give a class its own `self` at instantiation time

  - by SuperDisk

  I've got a button class that you can instantiate like so: engine.createElement((0, 0), Button(code=print, args=("Stuff!",))) And when it is clicked it will print "Stuff!". However, I need the button to destroy itself whenever it is clicked. Something like this: engine.createElement((0, 0), Button(code=engine.killElement, args=(self,))) However, that would just kill the caller, because self refers to the caller at that moment. What I need to do is give the class its own 'self' in advance... I thought of just making the string 'self' refer to the self variable upon click, but what if I wanted to use the string 'self' in the arguments? What is the way to do this? Is my architecture all wrong or something? Thanks.

• Can plugins loaded with MEF resolve their own internal dependencies with the same MEF container for

  - by Dave

  From my experimentation, I think the answer is "kind of", but I could have made a mistake. I have an application that loads appliance plugins with MEF. That part is working fine. Now let's say that my BlenderAppliance wants to resolve several of its dependencies with MEF, which each implement IApplianceFeature. I've just used the ImportMany attribute to my plugin. I made sure to create the plugin using MEF so that the Imports work properly. I said "kind of" because some of the plugin's internals (i.e. the model) are loading with MEF just fine, but the IApplianceFeatures aren't. The difference here is that the IApplianceFeatures are themselves, assemblies. And at the moment, they are in one folder above that of the plugin itself, i.e. + application folder | IApplianceFeature1.dll | IApplianceFeature2.dll +---+ plugin folder | BlenderAppliance.dll Now if my application uses an AggregateCatalog to load the "." and ".\plugins" folders, why doesn't it ever load the IApplianceFeature assemblies for me? Is it possible / advisable to have the plugin create its own MEF container to resolve its dependencies, or does really nasty stuff happen? If you have any stories about this scenario, please share. :)

• Java NoClassDefFoundError when calling own class from instrumented method

  - by lethal_possum

  Hello, I am working on a kit of simple Java agents to help me (and hopefully others) troubleshoot Java applications. One of the agents I would like to create instruments the JComponent.getToolTipText() method to quickly identify any GUI class by just hovering the mouse cursor over it. You can find the code of my transformer and the rest of the project here: http://sfn.cvs.sourceforge.net/viewvc/sfn/core/src/main/java/org/leplus/sfn/transformer/JComponentTransformer.java?view=markup I launch my test GUI with the agent attached as follow: $ java -javaagent:target/jars/sfn-0.1-agent.jar=JComponent -cp lib/jars/bcel-5.2.jar:target/jars/sfn-0.1-test.jar:target/jars/sfn-0.1-agent.jar org.leplus.sfn.test.Main sfn-0.1-agent.jar contains the org.leplus.sfn.transformer.JComponentTransformer class. sfn-0.1-test.jar contains the org.leplus.sfn.test.Main class. Here is what the application prints when I launch it and I put the mouse over it: Loading agent: JComponent Instrumentation ready! Exception in thread "AWT-EventQueue-0" java.lang.NoClassDefFoundError: org/leplus/sfn/tracer/ComponentTracer at javax.swing.JComponent.getToolTipText(JComponent.java) at javax.swing.ToolTipManager$insideTimerAction.actionPerformed(ToolTipManager.java:662) ... What is surprising to me is that if I change my transformer to call any class from the JRE, it works. But it doesn't work when I call my own class org.leplus.sfn.tracer.ComponentTracer. My first guess was a classpath issue but the ComponentTracer is both in the classpath and in the agent's jar. So I am lost. If any of you see where I am missing something. Cheers, Tom

• Code required to use foreach on my own custom appSettings

  - by jamauss

  I've searched the site and haven't found exactly what I'm looking for. Close, but no cigar. Basically I want to have a config section like this: <configSections> <section name="PhoneNotificationsSection" type="Alerts.PhoneAlertConfigSection,Alerts,Version=1.0.0.0,Culture=neutral,PublicKeyToken=null"/> </configSections> <PhoneNotificationsSection> <phones> <add phone="MyMobile" value="[email protected]" /> <add phone="OtherMobile" value="[email protected]" /> </phones> </PhoneNotificationsSection> Then I'd like to, in my appSettings consuming code, be able to write something like this (pseudo code): foreach (phone p in phones) { //'phone' attribute is just helpful/descriptive DoSomething(p.value); } I've done enough research to know I probably need a few of my own classes that implement and/or inherit from certain Configuration classes to make the above code possible. I just haven't found anything that clearly demonstrates this scenario and how to code for it - and when I try to learn the whole .NET configuration world my brain starts to hurt. Anyone have some code like what I'm looking for that they can share?
