• Advanced Registry Monitoring

  - by RyanTimmons91

  I'm attempting to create a small utility to watch for the creation (or modification) of a specific registry key, and to kill the process responsible for causing that registry modification. I have had success in watching the changes to the registry via a class called 'RegistryMonitor', however it does not give you any information on what process initiated the registry call, through some googling I found that a library called 'EasyHook' should be able to do what I want, but all the documentation states that its designed for a per-application hook. The program itself is a temporary security patch, until our vendors come out with an official security update. As best I can tell there isn't a way to do exactly what I want to accomplish from C#, which is the only language I can comfortable write, test and execute software in. Any help on this would be appreciated I'm considering watching the registry changes via the program I already have, then if the change is discovered (the pc is already infected) running RKill and locking down the PC to prevent the issue from getting any worse

• Analog of Java Form Layout in Qt

  - by Narek

  Once I have programmed GUI with Java and have used Form Layouts. Form layout (if I am not mistaken that is from SWT library) made possible to give right, left, top and bottom adges of any GUI element (widget) with respect to other widgets in the same widget (parent widget) or with respect to the adges of parent widget. So it was possible to control the future of widgets that are inside of another one, when that "another widget" is being resized. In Qt I have find the QFormLayout which is similar to Java one, but seems I can't handle with widgets as flexible in terms of relative positioning, as it was with Java's Form Layout. So are there any other means to give a widget position with respect to the others (without overloading resizeEvent function) as that was in Java? Thanks.

• Why can't my c++ program find the necessary .dll file?

  - by RemiX

  I am trying to use OpenCV (a computer vision library), which appearently uses a few .dll files, located in C:\OpenCV\bin (which has been added to the system PATH variable). However, if I try to run a simple test program, it gives a system error: "The program can't start because highgui.dll is missing from your computer. Try reinstalling the program to fix this problem." If I copy the highgui.dll file into the system32 folder, it works, but I don't want to have to put all the necessary .dll files in the system32 folder. Does anyone know why the .dll file can't be found or what I should do to fix it? (I already checked all paths in the PATH variable for validity.)

• what's the job of std::unique_lock when used with std::conditional_variable::wait()

  - by Mike

  I'm quite confused with the need of a std::unique_lock when wait a std::conditional_variable. So I look into the library code in VS 2013 and get more confused. This is how std::conditional_variable::wait() implemented: void wait(unique_lock<mutex>& _Lck) { // wait for signal _Cnd_waitX(&_Cnd, &_Lck.mutex()->_Mtx); } Is this some kind of joke? Wrap a mutex in a unique_lock and do nothing but get it back latter? Why not just use mutex in the parameter list?

• Sending MMS into different Android devices

  - by 6istik

  I need to send MMS. Into my hero this code looks ugly but works: Intent sendIntent = new Intent("android.intent.action.SEND_MSG"); sendIntent.putExtra("address", toText); sendIntent.putExtra(Intent.EXTRA_SUBJECT, "subject"); sendIntent.putExtra("sms_body", textMessage); sendIntent.putExtra(Intent.EXTRA_STREAM, Uri.parse(url)); sendIntent.setType("image/jpeg"); startActivity(sendIntent); But it seems to me that on the other devices it doesn't work at all. I want to send directly to main messaging app without any choices(the better solution of course - direct from my app). Because not sure that all of them would handle it properly. If anybody could recommend any third-party library I'll be appretiate.

• using "Reference3 Interface" to add desired references to a project

  - by BDotA

  I found this: http://msdn.microsoft.com/en-us/library/vslangproj80.reference3%28VS.80%29.aspx what I have in mind is that many of the references that we add to our project are on a network drive and there are TON of them. Adding references to the project by right clicking on the References in the porject and choosing add reference is a pain. so I was wondering if I can take advantage of something like what I posted the link to it and have a small program,add-in,macro, etc! that we can give it a list of the references that I want and it will add them to the project.

• iOS JavaScript bridge

  - by andr111

  I'm working on an app where I'm going to use both HTML5 in UIWebView and native iOS framework together. I know that I can implement communication between JavaScript and Objective-C. Are there any libraries that simplify implementing this communication? I know that there are several libraries to create native iOS apps in HTML5 and javascript (for example AppMobi, PhoneGap), but I'm not sure if there is a library to help create native iOS apps with heavy JavaScript usage. I need to: Execute JS methods from Objective-C Execute Objective-C methods from JS Listen to native JS events from Objective-C (for example DOM ready event)

• c# class design - what can I use instead of "static abstract"?

  - by Ryan

  I want to do the following public abstract class MyAbstractClass { public static abstract int MagicId { get; } public static void DoSomeMagic() { // Need to get the MagicId value defined in the concrete implementation } } public class MyConcreteClass : MyAbstractClass { public static override int MagicId { get { return 123; } } } However I can't because you can't have static abstract members. I understand why I can't do this - any recommendations for a design that will achieve much the same result? (For clarity - what I am trying to do is provide a library with an abstract base class but the concrete versions MUST implement a few properties/methods themselves and yes, there are good reasons for keeping it static.)

• Big numbers with fraction support

  - by dutt

  I need a c# number something that can handle very large numbers but also fraction support, I looked at System.Numberics.BigInteger coming in .NET 4.0 but I can't get it to work with fractions. something i = 2; something j = 5; something k = i/j; //should be 0.4 when i tried BigInteger i = 2; BigInteger j = 5; double d = (double)(i/j); //d is 0.0 Does anybody know such a library?

• c++ Mixing printf, cout with wprintf, wcout

  - by Bo Jensen

  I know you should not mix printing with printf,cout and wprintf,wcout, but have a hard time finding a good answer why and if it is possible to get round it. The problem is I use a external library that prints with printf and my own uses wcout. If I do a simple example it works fine, but from my full application it simply does not print the printf statements. If this is really a limitation, then there would be many libraries out there which can not work together with wide printing applications. Any insight on this is more than welcome.

• How to know if the argument that is passed to the function is a class, union or enum in c++?

  - by Narek

  I want to define an operator<< for all enums, to cout the value and print that it is an enum like this: code: enum AnyEnum{A,B,C}; AnyEnum enm = A; cout << enm <<endl; output: This is an enum which has a value equal to 0 I know a way of doing this with Boost library by using is_enum struct. But I don’t understand how it works. So that's why, in general, I am interested how to identify if the veriable is a class type, union type or an enum (in compile time).

• Is there a way to get the current UIEvent being handled?

  - by not-

  I'm working in a class that is a delegate of another class; this other class is in a third-party library that I'd like to avoid changing if at all possible. The original class is handling a -touchesEnded event, and is delegating responsibility to me, but it doesn't pass the UIEvent itself to me. Is there a way to get a handle to the current event in progress? It's a double-tap handler, and all that is passed to me is the view being touched, and the point at which the touch occurred. I want to know exactly how many touches are involved in the event. Thanks! randy

• Sharing data between two instances in a load balanced java web application

  - by rabbit

  I want to cache data in a java web application deployed on multiple instances. We are using spring 2.5.6. What is the easiest caching library to configure and use with spring? I have heard of EH Cache, but the configuration is too cumbersome. The requirement is that a spring scheduler will run and set some flags. These flags are accessible from all load balanced instances. But since the scheduler runs only on one instance the flag is set only on that jvm. So how do i make these updated flag values available to all load balanced instances?

• Optimal diff between object lists in Java

  - by Philipp

  I have a List of Java objects on my server which is sent to the client through some serialization mechanism. Once in a while the List of objects gets updated on the server, that is, some objects get added, some get deleted and others just change their place in the List. I want to update the List on the client side as well, but send the least possible data. Especially, I don't want to resend Objects which are already available on the client. Is there a library available which will produce some sort of diff from the two lists, so that I can only send the difference and the new Objects accross the wire? I have found several Java implementation of the unix diff command, but this algorithm is unpractical for order changes. ie. [A,B,C] - [C,B,A] could be sent as only place changes [1-3] [3-1], while diff will want to resend the whole A and C objects (as far as I understand).

• EntityFramework 4.0: can you return different types depending on data in the database?

  - by user200341

  I have a Media table in the database. I also have an IMedia interface. I have two different media types that implements the same interface: 1) AudioMedia 2) PictureMedia What I wonder here, is if I can use EntityFramework (I'm using an EDMX file but I have my models in a separate library, with automatic code generation turned off), and depending on the data in the database, select what type to get (AutioMedia or PictureMedia). Since they are both implementing the same interface (could be changed to an abstract class if needed I suppose), I'm thinking that somewhere along the way you could specify what class it should be. I should perhaps point out that I have a class that inherits from ObjectContext to access the objects. Perhaps there is something that that can be done?

• Handling orientation changes yourself

  - by synic

  From the documentation regarding the android:configChanges='orientation' attribute of the activity tag in the manifest: Note: Using this attribute should be avoided and used only as a last-resort. Please read Handling Runtime Changes for more information about how to properly handle a restart due to a configuration change. Why does it say this? In the case of threads and networking requests via a service API library, a request could be made with a reference to the original Activity, and then an orientation change could occur, leaving the thread pointing to the old Activity. While this can be fixed, it's tedious and ugly compared to just handling the configuration changes yourself. Why should it be avoided?

• The best way to store username and password without a database

  - by Mokuchan

  Hello everyone, I want to build a simple single user login "library" in PHP, but I'm facing the following dilemma: how should I store username and password if I'm not using a database? A simple plain text file could be easily read and then the password could be easily decripted so that's not an option. If I create a php file with just <?php $Username= "username"; $Password= "password"; ?> then no one should be able to read it and I could simply include this file where I need it, but I'm not really sure you can't find a better way to do this! So what's, in your opinion, the best solution to this problem (and why)? Thanks

• Fastest method in merging of the two: dicts vs lists

  - by tipu

  I'm doing some indexing and memory is sufficient but CPU isn't. So I have one huge dictionary and then a smaller dictionary I'm merging into the bigger one: big_dict = {"the" : {"1" : 1, "2" : 1, "3" : 1, "4" : 1, "5" : 1}} smaller_dict = {"the" : {"6" : 1, "7" : 1}} #after merging resulting_dict = {"the" : {"1" : 1, "2" : 1, "3" : 1, "4" : 1, "5" : 1, "6" : 1, "7" : 1}} My question is for the values in both dicts, should I use a dict (as displayed above) or list (as displayed below) when my priority is to use as much memory as possible to gain the most out of my CPU? For clarification, using a list would look like: big_dict = {"the" : [1, 2, 3, 4, 5]} smaller_dict = {"the" : [6,7]} #after merging resulting_dict = {"the" : [1, 2, 3, 4, 5, 6, 7]} Side note: The reason I'm using a dict nested into a dict rather than a set nested in a dict is because JSON won't let me do json.dumps because a set isn't key/value pairs, it's (as far as the JSON library is concerned) {"a", "series", "of", "keys"} Also, after choosing between using dict to a list, how would I go about implementing the most efficient, in terms of CPU, method of merging them? I appreciate the help.

• Problem with CFNetRegister

  - by xtrahotsauce

  I'm trying to work with CFNetServices by trying to start up and publish a service asynchronously. I'm trying to use the example code from here: http://developer.apple.com/mac/library/documentation/Networking/Conceptual/NSNetServiceProgGuide/Articles/CFNetServices.html#//apple_ref/doc/uid/30001276-SW3, but CFNetRegisterWithOptions always fails. (CFNetRegister is deprecated now). When I print out the error struct, it looks like this: (gdb) p error $1 = { domain = 10, error = -72004 } Which doesn't seem correct to me. Does anyone know what might be wrong? Thanks!

• How to hide classes to external namespaces? Something like the package-protected modifier in Java

  - by devoured elysium

  In java is easy to "hide" classes from outside your package(namespace), as you can define them as package-protected. There seems to be no equivalent keyword modifier in C#. Is there any way I could mimic that behaviour in C#? I have a couple of classes that I really wouldn't like the rest of the assembly to know of. It is ok for classes in the same namespace to know of, but I'd like them to be hidden from the rest of the library/application. I know of the internal keyword, but that only hiddes classes if you try to access them from outside your assembly. That is not really my case, as I'd like to keep everything glued in just one .DLL/.EXE. Thanks

• Preventing the "[YourProgramName] has stopped working" dialog on unhandled exceptions.

  - by Serapth

  I have a WinForm application, with some dependencies on an external library that can on occasion cause an exception outside of the running threads context. As it stands now, this is completely OK behavior ( well, except of course the exception ) and we wired up AppDomain.CurrentDomain.UnhandledException to simply restart the program. The only problem is, the [Your Program] has stopped working like the one below, appears: Is there a way to prevent this dialog from appearing at all, be it in the AppDomain unhandled exception handler or in a config setting, as no end users are going to be reading it and it just holds up resources until it is clicked.

• QuickTime movie disappearing from Javascript when scrolled offscreen in Firefox?

  - by c-had

  I have a web page I'm creating that uses Javascript to control an embedded QuickTime player. I add the QuickTime movie to the page using the AC_QuickTime.js file from Apple (as described here - http://developer.apple.com/mac/library/documentation/QuickTime/Conceptual/QTScripting_HTML/QTScripting_HTML_Document/ScriptingHTML.html#//apple_ref/doc/uid/TP40001525-2-SW1 ). Everything seems to be working fine - I can call methods on the QuickTime movie and control its playback (as well as get the current timestamp). The problem is that in Firefox, when I scroll down such that the QuickTime player is no longer visible, I get the following error every time I try to call a method on the QuickTime movie: Error calling method on NPObject! This does not occur in Safari. Why is this happening, and is there any way to work around this?

• .NET: Get all Outlook calendar items

  - by Qinnie

  How can I get all items from a specific calendar (for a specific date). Lets say for instance that I have a calendar with a recurring item every Monday evening. When I request all items like this: CalendarItems = CalendarFolder.Items; CalendarItems.IncludeRecurrences = true; I only get 1 item... Is there an easy way to get all items (main item + derived items) from a calendar? In my specific situation it can be possible to set a date limit but it would be cool just to get all items (my recurring items are time limited themselves). I'm using the Microsoft Outlook 12 Object library (Microsoft.Office.Interop.Outlook).
