  • WPF Binding Question - Change Label Text based on Modifier Key Control

    - by Chuck Savage
    I have a context menu, that I'd like to change the Header based on whether the Control Key is pressed or not. Right now I have, <MenuItem Header="Send To"> <MenuItem ... /> <MenuItem ... /> </MenuItem> I'd like based on the Control Key being down to be, <MenuItem Header="Move To"> <MenuItem ... /> <MenuItem ... /> </MenuItem> All I really need to do is change the Header text, because inside the code I know how to check for the Modifier key being Control.

  • Warning: preg_match() [function.preg-match]: Unknown modifier '/' problem

    - by SonOfOmer
    I am building custom implementation of php MVC routing engine, and I have custom routes like one in $routes array below. Each time when I send asynchronous GET request like xmlhttp.open("GET","someurl"); I get following message Warning: preg_match() [function.preg-match]: Unknown modifier '/' problem but with synchronous (normal) request it all works fine <?php $routes = array( array('url' => '/^someurl$/', 'controller' => 'somecontroller', 'view' => 'someview') ); $url = $_SERVER['REQUEST_URI']; $url = substr( $url, 1 ); $params = array(); $route_match = false; foreach($routes as $urls => $route) { if(preg_match($route['url'], $url, $matches)) { $params = array_merge($params, $matches); $route_match = true; break; } } require_once(CONTROLLER_PATH.$route['controller'].'.php'); ?> string(11) "/^someurl$/" is the result of var_dump($route['url']); Thanks.

  • Reflecting over classes in .NET produces methods only differing by a modifier

    - by mrjoltcola
    I'm a bit boggled by something, I hope the CLR gearheads can help. Apparently my gears aren't big enough. I have a reflector utility that generates assembly stubs for Cola for .NET, and I find classes have methods that only differ by a modifier, such as virtual. Example below, from Oracle.DataAccess.dll, method GetType(): class OracleTypeException : System.SystemException { virtual string ToString (); virtual System.Exception GetBaseException (); virtual void set_Source (string value); virtual void GetObjectData (System.Runtime.Serialization.SerializationInfo info, System.Runtime.Serialization.StreamingContext context); virtual System.Type GetType (); // here virtual bool Equals (object obj); virtual int32 GetHashCode (); System.Type GetType (); // and here } What is this? I have not been able to reproduce this with C# and it causes trouble for Cola as it thinks GetType() is a redefinition, since the signature is identical. My method reflector starts like this: static void DisplayMethod(MethodInfo m) { if ( // Filter out things Cola cannot yet import, like generics, pointers, etc. m.IsGenericMethodDefinition || m.ContainsGenericParameters || m.ReturnType.IsGenericType || !m.ReturnType.IsPublic || m.ReturnType.IsArray || m.ReturnType.IsPointer || m.ReturnType.IsByRef || m.ReturnType.IsPointer || m.ReturnType.IsMarshalByRef || m.ReturnType.IsImport ) return; // generate stub signature // [snipped] }

  • class modifier issues in C# with "private" classes

    - by devoured elysium
    I had a class that had lots of methods: public class MyClass { public bool checkConditions() { return checkCondition1() && checkCondition2() && checkCondition3(); } ...conditions methods public void DoProcess() { FirstPartOfProcess(); SecondPartOfProcess(); ThirdPartOfProcess(); } ...process methods } I identified two "vital" work areas, and decided to extract those methods to classes of its own: public class MyClass { private readonly MyClassConditions _conditions = new ...; private readonly MyClassProcessExecution = new ...; public bool checkConditions() { return _conditions.checkConditions(); } public void DoProcess() { _process.DoProcess(); } } In Java, I'd define MyClassConditions and MyClassProcessExecution as package protected, but I can't do that in C#. How would you go about doing this in C#? Setting both classes as inner classes of MyClass? I have 2 options: I either define them inside MyClass, having everything in the same file, which looks confusing and ugly, or I can define MyClass as a partial class, having one file for MyClass, other for MyClassConditions and other for MyClassProcessExecution. Defining them as internal? I don't really like that much of the internal modifier, as I don't find these classes add any value at all for the rest of my program/assembly, and I'd like to hide them if possible. It's not like they're gonna be useful/reusable in any other part of the program. Keep them as public? I can't see why, but I've let this option here. Any other? Name it! Thanks

  • Having an issue with the "this" modifier...

    - by user344246
    I have this method in City class. It should create a new city based on the object which the method is applied to: public City newCity(string newCityName, int dX, int dY) { City c=new City(this); //based on a constructor : City(City c){} c.CityName=newCityName; c.NoOfNeighborhoods=1; c.NumOfResidents=0; c.CityCenter.Move(dX,dY); return c; } CityCenter is of type "Point" which has two fields - x,y. the Move method in Point class is ment to change the CityCenter location. It looks like this: public void Move(int dX, int dY) { this.X = x + dX; this.Y = y + dY; } What happens is that the new object,c and the existing City object are both changed. I think that "this" modifier works on the existing object too... How can I take advantage of the Move method without causing this behavior? Note: this is a closed API, so I can only add private methods to the project.

  • What are some practical uses of the "new" modifier in C# with respect to hiding?

    - by Joel Etherton
    A co-worker and I were looking at the behavior of the new keyword in C# as it applies to the concept of hiding. From the documentation: Use the new modifier to explicitly hide a member inherited from a base class. To hide an inherited member, declare it in the derived class using the same name, and modify it with the new modifier. We've read the documentation, and we understand what it basically does and how it does it. What we couldn't really get a handle on is why you would need to do it in the first place. The modifier has been there since 2003, and we've both been working with .Net for longer than that and it's never come up. When would this behavior be necessary in a practical sense (e.g.: as applied to a business case)? Is this a feature that has outlived its usefulness or is what it does simply uncommon enough in what we do (specifically we do web forms and MVC applications and some small factor WinForms and WPF)? In trying this keyword out and playing with it we found some behaviors that it allows that seem a little hazardous if misused. This sounds a little open-ended, but we're looking for a specific use case that can be applied to a business application that finds this particular tool useful.

  • Keyboard Simulation not working with Keyboard hook for modifier keys

    - by Eduardo Wada
    I have a piece of software that is being used to simulate a certain device on a touchscreen, this device already runs an application that receives keyboard input from the device. My software (reffered to as simulator) displays a virtual keyboard and runs the application. Thus, the simulator sends keys with input simulator: http://inputsimulator.codeplex.com/ And the applciation listens to keys with the following keyboard hook: https://svn.cyberduck.io/tags/release-4-1/source/ch/cyberduck/core/GlobalKeyboardHook.cs My problem is, what some keys from the device's hardware actually do is to sent a key combination (ex: left-alt + 1) to the application and a weird scenario is occurring: The application listens to normal keyboard inputs The simulator sends keys to other applications (ie: visual studio responds to the keys sent when debugging) The simulator can send single keys to the application (I can type) The simulator CANNOT send key combinations to the application (alt+1 is received as just 1 in the application) This started happenning when we imported the application's dll into the same process from the simulator. Could there be any reason why I can't simulate key combinations for a hook in the same process? Is there any easy fix for this?

  • Compilation Error: "The modifier 'public' is not valid for this item" while creating public method o

    - by Lalit
    I am getting this error while creating public method on a class for explicitly implementing the interface. I have the workaround: by removing the explicit implementation of PrintName Method, But surprised why i am getting this error. Can anyone explain the error. Code for Library: using System; using System.Collections.Generic; using System.Linq; using System.Text; namespace Test.Lib1 { public class Customer : i1 { public string i1.PrintName() //Error Here... { return this.GetType().Name + " called from interface i1"; } } public interface i1 { string PrintName(); } interface i2 { string PrintName(); } } Code for Console Test Application: using System; using System.Collections.Generic; using System.Linq; using System.Text; using Test.Lib1; namespace ca1.Test { class Program { static void Main(string[] args) { Customer customer = new Customer(); Console.WriteLine(customer.PrintName()); //i1 i1o = new Customer(); //Console.WriteLine(i1o.printname()); //i2 i2o = new Customer(); //Console.WriteLine(i2o.printname()); } } }

  • Determine modifier key state without an InputEvent object in Java

    - by heycam
    I need to determine the current state of the Shift key, but at the time I need the state I don't have an InputEvent object around. I need something like java.awt.Toolkit.getLockingKeyState(int) that works for Shift, not just the locking keys like VK_CAPS_LOCK. Is there a way I can do this without listening to input events and storing the for later when I need to check the state? Thanks!

  • Why this cache doesn't work using final as modifier

    - by Pentium10
    I have this code to get the Cursor once for this instance, and the Log shows it is called many times although I marked as final. What I am missing? private Cursor getAllContactsCached() { final Cursor c=this.getList(); return c; } getAllContactsCached method should retrieve list once, and the 2nd time it should reuse the final object for return

  • Doxygen with C# internal access modifier

    - by Mike Gates
    I am using Doxygen to generate some API docs for a C# project I am working on. I have quite a bit of "internal" functionality in this project and don't want Doxygen producing these signatures in the generated html it produces. I have tried enabling HIDE_FRIEND_COMPOUNDS but this still results in my internal classes being exposed in the generated documentation. Does anyone know how to do this?

  • this parameter modifier in C#?

    - by Ivan
    I'm curious about this code snippet: public static class XNAExtensions { /// <summary> /// Write a Point /// </summary> public static void Write(this NetOutgoingMessage message, Point value) { message.Write(value.X); message.Write(value.Y); } // ... }; What does the this keyword mean next to the parameter type? I can't seem to find any information about it anywhere, even in the C# specification.

  • What Windows message is fired for mouse-up with modifier keys?

    - by Greg
    My WndProc isn't seeing mouse-up notifications when I click with a modifier key (shift or control) pressed. I see them without the modifier key, and I see mouse-down notifications with the modifier keys. I'm using the Windows Forms NativeWindow wrapper to get Windows messages from the WndProc() method. I've tried tracking the notifications I do get, and I the only clue I see is WM_CAPTURECHANGED. I've tried calling SetCapture when I receive the WM_LBUTTONDOWN message, but it doesn't help. Without modifier (skipping paint, timer and NCHITTEST messages): WM_LBUTTONDOWN WM_SETCURSOR WM_MOUSEMOVE WM_SETCURSOR WM_LBUTTONUP With modifier (skipping paint, timer and NCHITTEST messages): WM_KEYDOWN WM_PARENTNOTIFY WM_MOUSEACTIVATE WM_MOUSEACTIVATE WM_SETCURSOR WM_LBUTTONDOWN WM_SETCURSOR (repeats) WM_KEYDOWN (repeats) WM_KEYUP If I hold the mouse button down for a long time, I can usually get a WM_LBUTTONUP notification, but it should be possible to make it more responsive.. What am I missing? Thanks.

  • Is there any complications or side effects for changing final field access/visibility modifier from private to protected?

    - by Software Engeneering Learner
    I have a private final field in one class and then I want to address that field in a subclass. I want to change field access/visibility modifier from private to protected, so I don't have to call getField() method from subclass and I can instead address that field directly (which is more clear and cohessive). Will there be any side effects or complications if I change private to protected for a final field? UPDATE: from logical point of view, it's obvious that descendant should be able to directly access all predecessor fields, right? But there are certain constraints that are imposed on private final fields by JVM, like 100% initialization guarantee after construction phase(useful for concurrency) and so on. So I would like to know, by changing from private to protected, won't that or any other constraints be compromised?

  • Java Design Questions - Class, Function, Access Modifiers

    - by Ron
    I am newbie to Java. I have some design questions. Say I have a crawler application, that does the following: 1. Crawls a url and gets its content 2. Parses the contents 3. Displays the contents How do you decide between implementing a function or a class? -- Should the parser be a function of the crawler class, or should it be a class in itself, so it can be used by other applications as well? -- If it should be a class, should it be protected or public class? How do you decide between implementing a public or protected class? -- If I had to create a class to generate stats from the parsed contents for eg, should that class be protected (so only the crawler class can access it) or should it be public? Thanks Ron

  • Why i can not acces the protected properties in my web application

    - by GigaPr
    Hi i have a web application which has a Base class in which i define all the properties common to the web pages. The base class extends System.Web.UI.Page Furthermore i have a Base User control class where are defined all the properties common to the user controls. the Base User Control extends System.Web.UI.UserControl all the properties in both base classes are protected. All the web pages extends the base class . All the controls extends the base user control class. The problem is i can not access the properties defined in the base class from the user controls and I can not extend two classes in the base user controls The question is how can i access the properties defined in the Base class from within the user controls? I hope i have been clear Thanks

  • How do you map a solo press of a modifier key to its own function or mapping on Windows?

    - by Conrad.Dean
    Today on hacker news there was a clever article on custom shortcut keys. The author talks about a technique for remapping a modifier key such as CTRL to ESC if CTRL were pressed without a modifier. This is useful in vim because of how often you need to press ESC. Another technique he describes is mapping the open parenthesis, ( to the left shift key, and ) to the right shift key. If another key is pressed when shift is held down, the shift key behaves normally. The author describes the software he uses on OSX, but is there a way to do this on Windows? I've heard of AutoHotKey but it seems to only fire macros when simple keys are pressed, rather than the conditional state switch that this would require.

  • What does a static modifier on a constructor means?

  • 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

  • Can I make a "TCP packet modifier" using tun/tap and raw sockets?

    - by benhoyt
    I have a Linux application that talks TCP, and to help with analysis and statistics, I'd like to modify the data in some of the TCP packets that it sends out. I'd prefer to do this without hacking the Linux TCP stack. The idea I have so far is to make a bridge which acts as a "TCP packet modifier". My idea is to connect to the application via a tun/tap device on one side of the bridge, and to the network card via raw sockets on the other side of the bridge. My concern is that when you open a raw socket it still sends packets up to Linux's TCP stack, and so I couldn't modify them and send them on even if I wanted to. Is this correct? A pseudo-C-code sketch of the bridge looks like: tap_fd = open_tap_device("/dev/net/tun"); raw_fd = open_raw_socket(); for (;;) { select(fds = [tap_fd, raw_fd]); if (FD_ISSET(tap_fd, &fds)) { read_packet(tap_fd); modify_packet_if_needed(); write_packet(raw_fd); } if (FD_ISSET(raw_fd, &fds)) { read_packet(raw_fd); modify_packet_if_needed(); write_packet(tap_fd); } } Does this look possible, or are there other better ways of achieving the same thing? (TCP packet bridging and modification.)

  • jQuery: How to use modifier keys on form submit?

    - by Svish
    Say I have a form that looks like this: [ Animal name input field ] Add button If I type a name and hit enter, an animal with the given name is added to a table. Works fine. What I would like now is to call the current way of working "quick add" and add a new feature called "slow add", which I am not quite sure how to do. Basically what I want is that if for example the shift key is held down when enter or the button is clicked, I want the form submit method to do something slightly different. In my case I want it to open up a form where more details on the animal can be added before it is added to the table. Problem is I'm not quite sure how to do this. I have tried add a FireBug console.info(eventData) in my current submit function and I have found that the eventData contains an altKey, shiftKey and controlKey property, but they are always undefined even when I hold those keys down. So, does anyone know how I can do something special in my submit handler when certain modifier keys were pressed when the form was submitted?

  • Detecting modifier keys held down during startup in OS/X (or Windows)?

    - by Tom Swirly
    I've searched here and not found any question that really covers this. I have a cross-platform Windows-OS/X application in which I'd like to be able to detect whether modifier keys like shift or control are being held down while the application starts up. We'd like to do this to allow the application to start up without reading its preferences file, in case that somehow gets corrupted (we saw in testing a prefs bug, now fixed, that made the window size 0 by 0, for example). We're using the excellent and comprehensive cross-platform C++ library named Juce. Unfortunately, Juce's master tells me that he believes this is impossible on OS/X at least since you only get keyboard events and there is no way to read the state of the keys unless something changes. Is this true? Or is there some way around this? I'm almost sure I've used Mac programs that used this mechanism to bypass their preferences. Or... stepping up one level... is there another solution to providing the functionality of "run the program but don't read the prefs file" other than "holding a key down while launching the program"? This is consumer software so we can't expect too much from the user. The final solution will end up being a cross-platform one so hints on the Windows side will also be appreciated. Thanks, and be well! I'll report in with progress on my end.
