  • Is it a bad programming practise to have "Public" members inside an "Internal" class?

    - by Amby
    I mean, won;t it be more specific and appropriate if i "only" keep "protected","internal" and "private" members (field,method,property,event) in a class which is declared as "internal" ? I have seen this practice ( having "public" members in an "internal" class) in various code so just wanted to know is it a bad practice or does it has some benefit or advantage. [Only concerned about C#] Thanks for your interest.

  • WPF - LayoutUpdated event firing repeatedly

    - by Drew Noakes
    I've been adding a bit of animation to my WPF application. Thanks to Dan Crevier's unique solution to animating the children of a panel combined with the awesome WPF Penner animations it turned out to be fairly straightforward to make one of my controls look great and have its children move about with some nice animation. Unfortunately this all comes with a performance overhead. I'm happy to have the performance hit when items are added/removed or the control is resized, but it seems that this perf hit occurs consistently throughout the application's lifetime, even when items are completely static. The PanelLayoutAnimator class uses an attached property to hook the UIElement.LayoutUpdated.aspx) event. When this event fires, render transforms are animated to cause the children to glide to their new positions. Unfortunately it seems that the LayoutUpdated event fires every second or so, even when nothing is happening in the application (at least I don't think my code's doing anything -- the app doesn't have focus and the mouse is steady.) As the reason for the event is not immediately apparent to the event handler, all children of the control have to be reevaluated. This event is being called about once a second when idle. The frequency increases when actually using the app. So my question is, how can I improve the performance here? Any answer that assists would be appreciated, but I'm currently stuck on these sub-questions: What causes the LayoutUpdated event to fire so frequently? Is this supposed to happen, and if not, how can I find out why it's firing and curtail it? Is there a more convenient way within the handler to know whether something has happened that might have moved children? If so, I could bail out early and avoid the overhead of looping each child. For now I will work around this issue by disabling animation when there are more than N children in the panel.

  • How can I programmatically link an UIView or UIImageView with an event like "touch up inside"?

    - by Thanks
    Interface Builder will only allow me to hook up such events for an button. But like in HTML, I just want to haven an blank UIImageView where - as soon as the user taps it - a method is invoked. I hope there is some cool programmatically way of doing that, which I don't know about. UPDATE: In my View Controller that creates the UIImageView I tried to do this: SEL actionSelector = @selector(doSomethingWhenImageIsTouched:); [self.myUIImageView addTarget:nil action:actionSelector forControlEvents:UIControlEventTouchUpInside]; The compiler gives me a warning, that UIImageView may not respond to addTarget:... what do I have to do so that it works with an UIImageView. I see in the docs that UIImageView does not inherit from UIControl, but addTarget: is part of UIControl. UPDATE: I ended up creating an UIButton after creating the UIImageView. Then I set the frame of that button to the frame of the UIImageView, and alpha to 0.1f. For some reason, it will not work if alpha is 0.0f. And then, I did that cool addTarget: thing...

  • Integer Linear Programming Java: Multiple Open Source and Commercial tools are available. Which one

    - by Sandeep Jindal
    Hi, I need to use Integer Linear Programming API/Tool for my application. Though my application is in Java but I don’t mind calling an EXE (Tool) from Java providing input using file (MPS, etc). My search analysis is as follows: There are multiple Open Source and Commercial tools available to solve ILP Following I found and think are useful for my needs. 1. Gnu LP Kit(GLPK): I think this is the oldest and probably most stable and efficient 2. IP_Solve: Has good reviews about it. 3. JavaILP: Found this, but not much reviews about it 4. Apache Common-Math: Supports LP but not ILP, so ruled out. 5. Coin-OR Can you please suggest which one shall be the best in terms of stability, efficiency, acceptance, etc Regards Sandeep Jindal

  • C# How to find if an event is hooked up

    - by Nick
    I want to be able to find out if an event is hooked up or not. I've looked around, but I've only found solutions that involved modifying the internals of the object that contains the event. I don't want to do this. Here is some test code that I thought would work: // Create a new event handler that takes in the function I want to execute when the event fires EventHandler myEventHandler = new EventHandler(myObject_SomeEvent); // Get "p1" number events that got hooked up to myEventHandler int p1 = myEventHandler.GetInvocationList().Length; // Now actually hook an event up myObject.SomeEvent += m_myEventHandler; // Re check "p2" number of events hooked up to myEventHandler int p2 = myEventHandler.GetInvocationList().Length; Unfort the above is dead wrong. I thought that somehow the "invocationList" in myEventHandler would automatically get updated when I hooked an event to it. But no, this is not the case. The length of this always comes back as one. Is there anyway to determine this from outside the object that contains the event?

  • Is there a redraw-event for HTML5's canvas element?

    - by valmar
    As the title says, I need a notification when the content of a canvas element was redrawn. Is this possible? If not, a notification when the whole page was redrawn would also be ok (reDRAWN not reLOADED!). The reason why I need this is that I want to get the current FPS of an animation running inside a canvas.

  • How to make it easy for users to install my software? Does the programming language matter?

    - by lala
    I'm a beginner to intermediate programmer and I've learned some java and C#. I want to start thinking about making some simple programs that I can release to the world. Just some basic stuff like calendar software that will probably be free. Users want the install process to be quick and easy. To install a java program, I have to tell them to have java installed. To install a C# program, I have to tell them to have .NET installed. I'm worried this might put off some potential users who just want to double click an exe file, choose a directory and be pretty much done. So, I guess this is an either/or two part question: 1) Is there a programming language that makes it easier to set up an installer without requiring users to have other stuff installed? or: 2) Is there some way to set up an installer that checks the system to see if it has java/.NET/whatever, and then includes java/.Net/whatever in the installation if it's not already there?

  • How to check for an existing executable before running it in a post-build event in VS2008?

    - by wtaniguchi
    Hey all, I'm trying to use SubWCRev to get the current revision number of our SVN repository and put it in a file so I can show it in the UI. As I'm working with a Web App, I use the following post build command line: "SubWCRev.exe" "$(SolutionDir)." "$(ProjectDir)Content\js\revnumber.js.tpl" "$(ProjectDir)Content\js\revnumber.js" It works great, but now I want to make sure I have SubWCRev before running it, so I can skip this post build if a fellow developer is not running TortoiseSVN. I tried a few batch codes here, but couldn't figure this out. Any ideas? Thanks!

  • What is the best software to capture full-screen 3h programming session in Windows?

    - by Hugo S Ferreira
    Hi, I'm planning a laboratorial experiment to assess behavior of groups when programming using some tools under study. For that, I'll need to capture their entire screen to disk. Mostly, what will be displayed is code, so I'm not to worried with image quality. However, it's paramount that the team is not able to stop the recording by accident, and the tool should be rebust enough to hold at least 3h of video. If possible, it would be nice for researchers in other rooms to "watch" the video as it is recording. Actually, this last requirement reminded me that I could use a VNC recording software, and install a VNC client in each laboratory computer. Anyway, what is your experience with this? Which software do you recommend? Thanks.

  • How to effectively use WorkbookBeforeClose event correctly?

    - by Ahmad
    On a daily basis, a person needs to check that specific workbooks have been correctly updated with Bloomberg and Reuters market data ie. all data has pulled through and that the 'numbers look correct'. In the past, people were not checking the 'numbers' which led to inaccurate uploads to other systems etc. The idea is that 'something' needs to be developed to prevent the use from closing/saving the workbook unless he/she has checked that the updates are correct/accurate. The numbers look correct action is purely an intuitive exercise, thus will not be coded in any way. The simple solution was to prompt users prior to closing the specific workbook to verify that the data has been checked. Using VSTO SE for Excel 2007, an Add-in was created which hooks into the WorkbookBeforeClose event which is initialised in the add-in ThisAddIn_Startup private void wb_BeforeClose(Xl.Workbook wb, ref bool cancel) { //.... snip ... if (list.Contains(wb.Name)) { DailogResult result = MessageBox.Show("some message", "sometitle", MessageBoxButtons.YesNo); if (result != DialogResult.Yes) { cancel = true; // i think this prevents the whole application from closing } } } I have found the following ThisApplication.WorkbookBeforeSave vs ThisWorkbook.Application.WorkbookBeforeSave which recommends that one should use the ThisApplication.WorkbookBeforeClose event which I think is what I am doing since will span all files opened. The issue I have with the approach is that assuming that I have several files open, some of which are in my list, the event prevents Excel from closing all files sequentially. It now requires each file to be closed individually. Am I using the event correctly and is this effective & efficient use of the event? Should I use the Application level event or document level event? Is there a way to prevent the above behaviour? Any other suggestions are welcomed VS 2005 with VSTO SE

  • NAudio: How can I get a event that tells me that the MP3 file reached the end?

Then I tried to use the PlaybackState: public PlaybackState PlaybackState { get { if (_playbackDevice == null) return default(PlaybackState); return _playbackDevice.PlaybackState; } } But when the song ends it does not change to "stopped". But when I call Stopped it changes correctly. Can someone help me?

  • JavaScript: input validation in the keydown event

    - by c411
    Hi, I'm attempting to do info validation against user text input in the process of keydown event. The reason that I am trying to validate in the keydown event is because I do not want to display the characters those that are considered to be illegal in the input box at the beginning. The validation I am writing is like this, function validateUserInput(){ var code = this.event.keyCode; if ((code<48||code>57) // numerical &&code!==46 //delete &&code!==8 //back space &&code!==37 // <- arrow &&code!==39) // -> arrow { this.event.preventDefault(); } } I can keep going like this, however I am seeing drawbacks on this implmentation. Those are, for example, Conditional statement become longer and longer when I put more conditions to be examined. keyCodes can be different by browsers. I have to not only check what is not legal but also have to check what are exceptionals. In above examples, delete,backspace, and arrow keys are exceptionals. But the feature that I don't want to lose is having not to display the input in the textarea unless it passes the validation. (In case the user try to put illegal characters in the textarea, nothing should appear at all) That is why I am not doing validation upon keyup event. So my question is, Are there better ways to validate input in keydown event than checking keyCode by keyCode? Are there other ways to capture the user inputs other than keydown event before browser displays it? And a way to put the validation on it? Thanks for the help in advance.

  • event.clientX is readonly?

    - by Duracell
    Working in IE 8, mostly, but trying to write a portable solution for modern browsers. Using telerik controls. I'm catching the 'Showing' client-side event of the RadContextMenu and trying to adjust it's coordinates. The clientX, clientY and x,y members of the DOM event cannot be assigned a new value. Visual Studio breaks with a "htmlfile: Member not found" error. My goal is to get a RadContextMenu to show inside a RadEditor when the user clicks in it (under certain conditions, this is a requirement from management). So I capture the onclick event for the RadEditor's content area (radEditor.get_document().body;). I then call show(evt) on the context menu, where 'evt' is the event object corresponding to the click event. Because the RadEditor's content is in an IFRAME, you have to adjust the position of the click event before the context menu displays. This is done in the "Showing" event. However, I cannot assign a value to the members .clientX and friends. It's as if javascript has temporarily forgotten about integer + and += operators. Is it possible that these members have become readonly/const at some point? var evt = args.get_domEvent(); while (node) { evt.clientX += node.offsetLeft; //'Member not found' here. evt.clientY += node.offsetTop; node = node.offsetParent; } evt.clientY += sender.get_element().clientHeight;

  • Receiving client-event on a GtkWindow

    - by fret
    I'm trying to send and receive a client-event using a GtkWindow on the win32 platform. The sending code looks like this: GtkWidget *Wnd; GdkNativeWindow Hnd = #ifdef WIN32 GDK_WINDOW_HWND(Wnd->window); #else GDK_WINDOW_XWINDOW(Wnd->window); #endif GdkEvent *Event = gdk_event_new(GDK_CLIENT_EVENT); // fill out Event params gdk_event_send_client_message(Event, Hnd); Receiving code looks like this: static gboolean MyClientEvent(GtkWidget *widget, GdkEventClient *ev, MyWnd *Wnd) { // breakpoint here... return TRUE; } GtkWidget *Wnd = gtk_window_new(GTK_WINDOW_TOPLEVEL); g_signal_connect( G_OBJECT(Wnd), "client-event", G_CALLBACK(MyClientEvent), this); gtk_widget_add_events(Wnd, GDK_ALL_EVENTS_MASK); I used Spy++ to see the message getting sent, so I know the sending side is ok. The receiving side however doesn't get the client-event. I was expecting my breakpoint in the callback to trigger... but it doesn't. I'm not even sure if a GtkWindow can receive a client-event... from past experience on X11 I thought it was pretty much the same as any other GtkWidget in that respect. Maybe on the win32 platform it's kinda different. But still I'd like to be able to get this working.

  • Raising C# events with an extension method - is it bad?

    - by Kyralessa
    We're all familiar with the horror that is C# event declaration. To ensure thread-safety, the standard is to write something like this: public event EventHandler SomethingHappened; protected virtual void OnSomethingHappened(EventArgs e) { var handler = SomethingHappened; if (handler != null) handler(this, e); } Recently in some other question on this board (which I can't find now), someone pointed out that extension methods could be used nicely in this scenario. Here's one way to do it: static public class EventExtensions { static public void RaiseEvent(this EventHandler @event, object sender, EventArgs e) { var handler = @event; if (handler != null) handler(sender, e); } static public void RaiseEvent<T>(this EventHandler<T> @event, object sender, T e) where T : EventArgs { var handler = @event; if (handler != null) handler(sender, e); } } With these extension methods in place, all you need to declare and raise an event is something like this: public event EventHandler SomethingHappened; void SomeMethod() { this.SomethingHappened.RaiseEvent(this, EventArgs.Empty); } My question: Is this a good idea? Are we missing anything by not having the standard On method? (One thing I notice is that it doesn't work with events that have explicit add/remove code.)

  • Do employers like to see (programming/computer science) blogs?

    - by incrediman
    I'm wondering if having a blog (with most posts concentrating on computer science/programming) would be a good idea with regards to getting a job. Would a potential employer like to see something like that? What about someone hiring a freelancer? I'd especially appreciate: Responses from people who hire programmers or computer scientists for full-time jobs. Responses from people who hire freelance programmers. Responses from people who have such such blogs and have felt their (either negative or positive) effects. Thanks! I felt this would probably be best marked as community wiki - please let me know if I was mistaken.

  • How to pass Event as a parameter in JQuery function

    - by Manas Saha
    Hi I am learning JQuery and I have written a small function where I am attaching a function with a button's click event. this is the head element of the HTML <script type="text/javascript"> $(pageLoaded); function pageLoaded() { $("#Button1").bind("click", { key1: "value1", key2: "value2" }, function buttonClick(event) { $("#displayArea").text(event.data.key1); } ); } </script> This is the body of the HTML <input id="Button1" type="button" value="button" /> <div id = "displayArea" style="border:2px solid black; width:300px; height:200px"> This code works fine. But when I try to write the buttonClick function outside the anonymus method, it does not work anymore. I tried to call it this way: $("#Button1").bind("click", { key1: "value1", key2: "value2" }, buttonClick(event)); function buttonClick(var event) { $("#displayArea").text(event.data.key1); } This is not working. Am I doing some mistake while passing the Event as parameter? what is the correct way to do it without using anonymous methods?

    Does "Value Restriction" mean that there is no higher order functional programming? I have a problem that each time I try to do a bit of HOP I get caught by a VR error. Example: let simple (s:string)= fun rq->1 let oops= simple "" type 'a SimpleType= F of (int ->'a-> 'a) let get a = F(fun req -> id) let oops2= get "" and I would like to know whether it is a problem of a prticular implementation of VR or it is a general problem that has no solution in a mutable type-infered language that doesn't include mutation in the type system.

  • What programming language is used to design google algorithm?

    - by AKN
    It is known that google has best searching & indexing algorithm. The also have good relevancy. They are also quicker in getting down the latest results. All that's fine. What programming language (c, c++, java, etc...) & database (oracle, MySQL, etc...) they have used in achieving this. Since they have to manipulate with volume of data quickly and effectively. Though I'm not looking for their indepth architecture (if in case violates their company policies) an overview of all such things could be useful. Anybody please add you valuable suggestions and insight on this?
