  • How to emulate pressing the Close button from a script?

    - by Karthik
    I wanted Thunderbird to stay in the Background to notify me of incoming mails. After a bit of searching, I found this post. How to keep Thunderbird and Pidgin running on background? The solution is to install an addon so that when we close Thunderbird it just stays in the background. Now, to have thunderbird running at Start up we can just add it to Startup Applications. But, when I open my system, Thunderbird also gets opened and I have to manually press the close button everytime to make Thunderbird go into the background. The solution given in the above post for this problem is to select Minimize on start. But doing so affects the way in which Thunderbird works when invoked from the Messaging menu. So I deselected this option. But, if there is a way to emulate pressing the Close button from a script, I can just add that script to Startup Applications So is there a way to achieve this? Note : If there is a simpler way to solve my original problem of keeping Thunderbird in background please post that also. Many thanks.

  • Closing Windows Forms on a Touchscreen

    - by drharris
    Our clients have fat fingers, and so do we. We take touchscreen netbooks apart to insert them into our custom hardware, and I write a software interface that shows up on the touchscreen. The problem is that it has about a 3/4" bezel over the screen, which means hitting that little red "X" becomes a challenge, especially considering reduced capacitive ability on the edges and corners. Is there a way to make this standard close button larger? Of course in the application I can always make really nice 80x80 buttons that are perfectly usable, but there seems to be no way to override the default frame of the form. We have tried enabling Large Fonts and all the built-in accessibility features, but nothing seems to make it large enough to hit successfully. Simply adding a toolbar button is also not much of an option. We prefer to utilize the standard look and feel of a normal Windows application. Alternatively, should we be looking at making some sort of "kiosk mode" where we simply go fullscreen and do nothing involving the taskbar or title bar? How difficult is this to accomplish, if so?

  • How are views constructed in Josh Smith's MVVM sample?

    - by Wim Coenen
    Being new to both WPF and MVVM, I'm studying Josh Smith's article on the MVVM pattern and the accompanying sample code. I can see that the application is started in app.xaml.cs by constructing a MainWindow object, wiring it to a MainWindowViewModel object and then showing the main window. So far so good. However, I can't find any code which instantiates the AllCustomersView or CustomerView classes. Using "find all references" on the constructors of those views comes up with nothing. What am I missing here?

  • What can cause a spontaneous EPIPE error without either end calling close() or crashing?

    - by Hongli
    I have an application that consists of two processes (let's call them A and B), connected to each other through Unix domain sockets. Most of the time it works fine, but some users report the following behavior: A sends a request to B. This works. A now starts reading the reply from B. B sends a reply to A. The corresponding write() call returns an EPIPE error, and as a result B close() the socket. However, A did not close() the socket, nor did it crash. A's read() call returns 0, indicating end-of-file. A thinks that B prematurely closed the connection. Users have also reported variations of this behavior, e.g.: A sends a request to B. This works partially, but before the entire request is sent A's write() call returns EPIPE, and as a result A close() the socket. However B did not close() the socket, nor did it crash. B reads a partial request and then suddenly gets an EOF. The problem is I cannot reproduce this behavior locally at all. I've tried OS X and Linux. The users are on a variety of systems, mostly OS X and Linux. Things that I've already tried and considered: Double close() bugs (close() is called twice on the same file descriptor): probably not as that would result in EBADF errors, but I haven't seen them. Increasing the maximum file descriptor limit. One user reported that this worked for him, the rest reported that it did not. What else can possibly cause behavior like this? I know for certain that neither A nor B close() the socket prematurely, and I know for certain that neither of them have crashed because both A and B were able to report the error. It is as if the kernel suddenly decided to pull the plug from the socket for some reason.

  • bluetooth BluetoothSocket.connect() thread. how to close this thread

    - by Hia
    I am trying to make an android app that makes connection with bluetooth device. It works fine but when I call BluetoothSocket.connect() and it is not able to connect to devise its blocking. The thread and does not throw any exception. So when I try to close application while connect() is running its not responding. How can I cancel it? Used BluetoothSocket.close() in ... but still its not working for me. protected void simpleComm(Integer port) { // The documents tell us to cancel the discovery process. try { Method m = mmDevice.getClass().getMethod("createRfcommSocket", new Class[] { int.class }); mmSocket = (BluetoothSocket) m.invoke(mmDevice, port); mmSocket.connect(); // <== blocks untill is not connected Log.d(TAG, " connection success==="); }catch(Exception e){ if (!abort) { connectionFailed(); // Close the socket try { mmSocket.close(); // Start the service over to restart listening mode BluetoothService.this.start(); } catch (IOException e2) { Log.e(TAG,"unable to close() socket during connection failure", e2); } } return; } } public void cancel() { try { abort = true; mmSocket.close(); } catch (IOException e) { Log.e(TAG, "close() of connect socket failed", e); } }

  • Windows 8: How to Lock (not sleep) laptop on lid close?

    - by Eye of Hell
    If my laptop is connected to power source and is not configured to sleep on lid close (it is connected to power source and is working, i don't want it to sleep. It's compiling my code) if i close the lid, laptop will do nothing. This works as expected, but actually if i have my laptop connected to power source in the office it will be good to lock it if i close a lid. So no one can just open the lid and see my unlocked desktop. I searched google and it says thet correct use case is to manually lock laptop via Win + L every time before lid is closed. This is ok, but not very secure - after all, i can forget Win + L. Is t any easy way (maybe some registry value or app) to configure windows laptop so it will lock on lid close even without sleep? Of course i can write app / powershell script for this task, but this is not suitable for non-programmers end users.

  • Server doesn't notice when client closes socket (.NET CF & GPRS)

    - by HansA
    Client written in .NET Compact Framework running over GPRS connection. Client connects a socket to the server. The server accepts the connection. Client sends 62 bytes of data and then closes the socket. Server never detects that the client has closed the socket and is therefore not able to know that the transfer has completed. This code works fine when run over a wireless connection. Any ideas?

  • FindBugs: "may fail to close stream" - is this valid in case of InputStream?

    - by thSoft
    In my Java code, I start a new process, then obtain its input stream to read it: BufferedReader reader = new BufferedReader(new InputStreamReader(process.getInputStream())); FindBugs reports an error here: may fail to close stream Pattern id: OS_OPEN_STREAM, type: OS, category: BAD_PRACTICE Must I close the InputStream of another process? And what's more, according to its Javadoc, InputStream#close() does nothing. So is this a false positive, or should I really close the input stream of the process when I'm done?

  • wpf exit thread automatically when application closes

    - by toni
    Hi, I have a main wpf window and one of its controls is a user control that I have created. this user control is an analog clock and contains a thread that update hour, minute and second hands. Initially it wasn't a thread, it was a timer event that updated the hour, minutes and seconds but I have changed it to a thread because the application do some hard work when the user press a start button and then the clock don't update so I changed it to a thread. COde snippet of wpf window: <Window xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:local="clr-namespace:GParts" xmlns:Microsoft_Windows_Themes="clr-namespace:Microsoft.Windows.Themes assembly=PresentationFramework.Aero" xmlns:UC="clr-namespace:GParts.UserControls" x:Class="GParts.WinMain" Title="GParts" WindowState="Maximized" Closing="Window_Closing" Icon="/Resources/Calendar-clock.png" x:Name="WMain" > <...> <!-- this is my user control --> <UC:AnalogClock Grid.Row="1" x:Name="AnalogClock" Background="Transparent" Margin="0" Height="Auto" Width="Auto"/> <...> </Window> My problem is when the user exits the application then the thread seems to continue executing. I would like the thread finishes automatically when main windows closes. code snippet of user control constructor: namespace GParts.UserControls { /// <summary> /// Lógica de interacción para AnalogClock.xaml /// </summary> public partial class AnalogClock : UserControl { System.Timers.Timer timer = new System.Timers.Timer(1000); public AnalogClock() { InitializeComponent(); MDCalendar mdCalendar = new MDCalendar(); DateTime date = DateTime.Now; TimeZone time = TimeZone.CurrentTimeZone; TimeSpan difference = time.GetUtcOffset(date); uint currentTime = mdCalendar.Time() + (uint)difference.TotalSeconds; christianityCalendar.Content = mdCalendar.Date("d/e/Z", currentTime, false); // this was before implementing thread //timer.Elapsed += new System.Timers.ElapsedEventHandler(timer_Elapsed); //timer.Enabled = true; // The Work to perform ThreadStart start = delegate() { // With this condition the thread exits when main window closes but // despite of this it seems like the thread continues executing after // exiting application because in task manager cpu is very busy // while ((this.IsInitialized) && (this.Dispatcher.HasShutdownFinished== false)) { this.Dispatcher.Invoke(DispatcherPriority.Normal, (Action)(() => { DateTime hora = DateTime.Now; secondHand.Angle = hora.Second * 6; minuteHand.Angle = hora.Minute * 6; hourHand.Angle = (hora.Hour * 30) + (hora.Minute * 0.5); DigitalClock.CurrentTime = hora; })); } Console.Write("Quit ok"); }; // Create the thread and kick it started! new Thread(start).Start(); } // this was before implementing thread void timer_Elapsed(object sender, System.Timers.ElapsedEventArgs e) { this.Dispatcher.Invoke(DispatcherPriority.Normal, (Action)(() => { DateTime hora = DateTime.Now; secondHand.Angle = hora.Second * 6; minuteHand.Angle = hora.Minute * 6; hourHand.Angle = (hora.Hour * 30) + (hora.Minute * 0.5); DigitalClock.CurrentTime = hora; })); } } // end class } // end namespace How can I exit correctly from thread automatically when main window closes and then application exits? Thanks very much!

  • Java Socket Disconnect Reporting vs. C# Disconnection

    - by ikurtz
    in C# when a sockets connection is terminated the other node is informed of this before terminating the link thus the remaning node can update the connection status. in Java when i terminate a communication link the other node keeps reporting the connection as valid. do i need to implement a read cycle (makes sense) that reports the connection as lost when it recieves a -1 during read (in C# this is 0 i think)? thank you for your insight. EDIT: thanks to you both. as i suspected and mentioned in my post that an additional check is required to confirm the connected state of a connection.

  • How to know when to close socket when dealing with HTTP clients?

    - by Y_Y
    Hi, How can I know when to close the socket of an HTTP client (I mean a browser is connecting to my TCP socket server). Everything works perfect but in other for the browser to show what the server has sent, i have to shutdown the server (or call socket.Close()). It works fine if I call (socket.Close()) but I just don't know when.? I don't want to call close in a middle of a request otherwise the browser would have to reload to connect to the server again.

  • Should I close database connections after use in PHP?

    - by Sprottenwels
    I wonder if I should close any unnecessary database connection inside of my PHP scripts. I am aware of the fact that database connections are closed implicitly when the block stops executing and 'manually' closing the connections could kinda bloat the codebase with unnecessary code. But shouldn't I do so in order to make by code as readable and as easy understandable as possible, while also preventing several possible issues during run time? Also, if I would do, would it be enough to unset() my database object?

  • How Can I Close the Leftmost Window in Vim?

    - by msutherl
    I'm trying to write a command that will close a tree-browser (vim-tree) window and resize the other windows. ,to opens the window and adjusts the window size so that all open windows retain a normal size (using :set columns+=30CTRL-W =). ,tc should close the tree window (full-length, far left) and resize the main window (:set columns-=30). How can I write a command that closes the leftmost window so that I can type ,tc to close the window and resize in one shot? I can navigate to it with CTRL-W h, but it is inelegant and potentially annoying (audible bell!) to use 10CTRL-W h in the command. :topleft c unfortunately doesn't work. Can you think of an elegant way to do this?

  • How do I get Acrobat Pro X to close files without quitting?

    - by CyberSkull
    Adobe Acrobat Pro X doesn't seem to want to relinquish files after I close them. When working on some PDFs after I save and close them, I then go to move (not copy) them to the appropriate done folder on our server. Then I get a series of errors saying that Windows cannot move the file as Acrobat Pro X has it open. Looking at the Acrobat window, the file is not loaded. Is there a way to get Acrobat Pro X to close the file like normal (without quitting the program) and actually release the file to the OS?
