  • Acer Allionone Z5810 Touchscreen Issues 12.04

    I have an Acer Allionone Z5810, and I can't get the touchscreen to work after I install 12.04.

  • Idea of an algorithm to detect a website's navigation structure?

    - by Uwe Keim
    Currently I am in the process of developing an importer of any existing, arbitrary (static) HTML website into the upcoming release of our CMS. While the downloading the files is solved successfully, I'm pulling my hair off when it comes to detect a site structure (pages and subpages) purely from the HTML files, without the user specifying additional hints. Basically I want to get a tree like: + Root page 1 + Child page 1 + Child page 2 + Child child page1 + Child page 3 + Root page 2 + Child page 4 + Root page 3 + ... I.e. I want to be able to detect the menu structure from the links inside the pages. This has not to be 100% accurate, but at least I want to achieve more than just a flat list. I thought of looking at multiple pages to see similar areas and identify these as menu areas and parse the links there, but after all I'm not that satisfied with this idea. My question: Can you imagine any algorithm when it comes to detecting such a structure? Update 1: What I'm looking for is not a web spider, but an algorithm do create a logical tree of the relationship of the pages to be able to create pages and subpages inside my CMS when importing them. Update 2: As of Robert's suggestion I'll solve this by starting at the root page, and then simply parse links as you go and treat every link inside a page simply as a child page. Probably I'll recurse not in a deep-first manner but rather in a breadth-first manner to get a more balanced navigation structure.

  • "KeyPress" event for WinForms textbox is missing?

    - by eibhrum
    I am trying to add an "KeyPress" event in a textbox (WinForm) this.textBox1.KeyPress += new System.Windows.Forms.KeyPressEventHandler(CheckKeys); and here's inside the 'CheckKeys': private void CheckKeys(object sender, System.Windows.Forms.KeyPressEventArgs e) { if (e.KeyChar == (char)13) { // Enter is pressed - do something } } The idea here is that once a textbox is in focus and the 'Enter' button was pressed, something will happen... However, my machine cannot find the 'KeyPress' event. Is there something wrong with my codes? UPDATE: I also tried putting KeyDown instead of KeyPress: private void textBox1_KeyDown(object sender, System.Windows.Input.KeyEventArgs e) { if (e.Key == Key.Return) // Enter is pressed - do something } } Still not working though...

  • What's the best way to handle the same shortcut in WPF and WinForms controls?

    - by Anthony Brien
    I have a WPF application with the following KeyBinding on its main window: <KeyBinding Command="Commands:EditCommands.Undo" Gesture="CTRL+Z" /> <KeyBinding Command="Commands:EditCommands.Redo" Gesture="CTRL+Y" /> This makes the command respond to the shortcut fine. However, in all the places where I have embedded WinForms text boxes or rich text boxes, I've lost the ability to use those shortcuts. If I remove the above bindings, the WinForms shortcuts work fine. How can I support these shortcuts in both WinForms and WPF? I'd prefer a generic method since this problem is likely to affect many other commands with the same keybindings.

  • simulate backspace key with java.awt.Robot

    - by Tyler
    There seems to be an issue simulating the backspace key with java.awt.Robot. This thread seems to confirm this but it does not propose a solution. This works: Robot rob = new Robot(); rob.keyPress(KeyEvent.VK_A); rob.keyRelease(KeyEvent.VK_A); This doesn't: Robot rob = new Robot(); rob.keyPress(KeyEvent.VK_BACK_SPACE); rob.keyRelease(KeyEvent.VK_BACK_SPACE); Any ideas? Thanks!

  • How does CommandManager.RequerySuggested work?

    - by Andrei Rinea
    The MSDN only states that Occurs when the CommandManager detects conditions that might change the ability of a command to execute. However I can't seem to find any traces of how this works, what I should be aware of / avoid etc... Does it just listen for input? (i.e.: mouse moves, keys pressed and so on)

  • Setting winforms ToolStripMenuItem ShortcutKeys to numpad key does not work

    - by Axarydax
    We have the ability to define ShortcutKeys for WinForms application menu items. That way I can tell a menu item File-Save to have a shortcut key Ctrl+S and the menu item's handler is "magically" executed after pressing Ctrl+S. The trouble is with the numeric keypad keys, the ShortcutKey property does not accept them (I don't understand how are they different from the other acceptable keys. MSDN states that the property accepts type System.Windows.Forms.Keys (One of the Keys values. The default is None.); and an InvalidEnumArgumentException would be thrown when the parameter is not one of Keys values. But for example Keys.Divide IS one of Keys values, and yet it can't be used. So how can I set a menu item to have a shortcut for Numpad * or Numpad +? Do I need to handle the key in Form's ProcessCmdKey event? Thanks

  • Is the switch to Dvorak worth it?

    - by Kevin Weil
    To those who were experienced ( 70 WPM, say) typists before the switch to Dvorak -- were you faster after switching? There are a couple good SO threads on Dvorak, but they are more on how to learn or reduction in typing pain than speed before/after. I know it will take me 1-2 months to feel comfortable, but I want to know if I should expect to be faster afterward. I am a programmer and type maybe 90-110 WPM on QWERTY. EDIT: I agree that coding is not typically IO-bound, and that a minimum typing speed is sufficient. This is half from curiosity, but it will be an undertaking to achieve QWERTY parity, so I want to know if I should at least expect some asymptotic improvement.

  • StackOverflow Code Sample vs }

    - by 0plus1
    I want to ask you a question about the stackoverflow's editor. Whenever I need to write code and close a } I get the Code Sample indentation if using: Alt gr + Shift + (+*]) It's pretty annoying, is there any way to avoid this other than: Ctrl+v ? Thank you and sorry if this has been asked before.

  • How to Redirect Visual Studio F12 Shortcut Key to Object Browser in C# Project

    - by AMissico
    For C# projects, I would like to have the F12 "Go to Definition" shortcut key to open the Object Browser and select the type under the cursor position. This is the behavior for VB.NET projects, which I really like. I think the Object Browser is more helpful than IntelliSense in some cases. I really do not need a text representation of the metadata. How do I duplicate the F12 / "Go to Definition" functionality in a C# project? Is there a different shortcut key for C#? I am not talking about the Alt+Ctrl+J shortcut key that displays the Object Browser.

  • How to get keypressed, keydown events from DataGridView data cells

    - by extropy
    Hi. I need to recieve the key press events during cell editing in DataGridView control. From what I have found on the net the DataGridView is designed to pass all key events from DataGridView to the cell editing control and you cannot get these events easily. I found this peace of code http://www.codeproject.com/KB/grid/DataGridCellEvents.aspx that traps those events for DataGrid control, but that does not work for DataGridView.

  • NSWindow does not respond to keystroke command-s

    - by wackazong
    Hello, it may pre very simple, but cannot find it: I have three windows in three separate NIBs in my application. One is opened when a new document is opened, the other two can be opened from the program's window menu. The problem is: two windows (in them the one that is opened at the beginning) accepts the normal keystroke as for example command-s for save, and the other one does not and gives a warning sound instead. I cannot figure out the difference between the two windows or their controllers. I know it will have to do with the responder chain, but I am left clueless. Any ideas? Thanks, wackazong

  • How do I test SendInput in c#

    - by JoelHess
    How can I tell if my call to SendInput is working properly? I have a small snippet below, and the message never seems to get hit. SendInput() returns 1, and there's no errors, so I assume that the message is going out properly. I've also tried the Form KeyPress and KeyDown Events, and I never seem to get those either. private void button1_Click(object sender, EventArgs e) { INPUT input = new INPUT(); input.mkhi.ki.wVk = (byte)System.Windows.Forms.Keys.B; uint result = SendInput(1, ref input, Marshal.SizeOf(new INPUT())); } protected override void WndProc(ref Message m) { if (m.Msg == WM_KEYDOWN) { Console.WriteLine("GotIt"); } base.WndProc(ref m); }

  • Override default behavior of SPACE key in .net WinForms ListView

    - by Axarydax
    Hello, I'd like to implement some custom behavior of Space key in a ListView. Basically I'd like to toggle selected status of the item under cursor - that should be fairly simple this.FocusedItem.Selected = !this.FocusedItem.Selected; but alas, it also does the default action, which is to select the focused item. This way I am unable to 'unselect' the focused item. I've looked for similar problems and they suggest using PreviewKeyDown event, in which I would process the key and disallow the ListView to do its default action. But the PreviewKeyDown event argument has no "handled" property, so I cannot 'eat' this key.

  • C#, WinForms: Why aren't KeyDown events chaining up to Form? I have to add event handler to each chi

    - by blak3r
    As i understand it, when a button is pressed it should first invoke the Control which has focus' KeyDown Handler, then it call the KeyDown handler for any Parent controls, all the way up to the main form. The only thing that would stop the chain would be if somewhere along the chain one of the EventHandlers did: e.SuppressKeyPress = true; e.Handled = true; In my case, KeyDown events never get to the main form. I have Form - Panel - button for example. Panel doesn't offer a KeyDown Event, but it shouldn't stop it from reaching the main form right? Right now as a work around I set every single control to call an event handler I wrote. I'm basically trying to prevent Alt-F4 from closing the application and instead minimize it.

  • batch file that detects keystrokes. how?

    - by daniel11
    im designing a collection of video games for the command line (such as deal or no deal, tic tac toe, racing, maze puzzle, connect four, wack a mole, etc.) however it would really make things easier for me if i could make it so that when the user makes a selection (such as what direction to move in the game) , that as soon as they press the arrow keys then it carries out the IF statements that follow. Instead of having to press enter after each selection. something like... :one1 set /p direction1= : IF %direction1%== {ARROW KEY LEFT} goto two2 IF %direction1%== {ARROW KEY RIGHT} goto three3 IF %direction1%== {ARROW KEY UP} goto four4 IF %direction1%== {ARROW KEY DOWN} goto five5 goto one1 Any Ideas?

  • Capture *all* display-characters in JavaScript?

    - by Jean-Charles
    I was given an unusual request recently that I'm having the most difficult time addressing that involves capturing all display-characters when typed into a text box. The set up is as follows: I have a text box that has a maxlength of 10 characters. When the user attempts to type more than 10 characters, I need to notify the user that they're typing beyond the character count limit. The simplest solution would be to specify a maxlength of 11, test the length on every keyup, and truncate back down to 10 characters but this solution seems a bit kludgy. What I'd prefer to do is capture the character before keyup and, depending on whether or not it is a display-character, present the notification to the user and prevent the default action. A white-list would be challenging since we handle a lot of international data. I've played around with every combination of keydown, keypress, and keyup, reading event.keyCode, event.charCode, and event.which, but I can't find a single combination that works across all browsers. The best I could manage is the following that works properly in =IE6, Chrome5, FF3.6, but fails in Opera: NOTE: The following code utilizes jQuery. $(function(){ $('#textbox').keypress(function(e){ var $this = $(this); var key = ('undefined'==typeof e.which?e.keyCode:e.which); if ($this.val().length==($this.attr('maxlength')||10)) { switch(key){ case 13: //return case 9: //tab case 27: //escape case 8: //backspace case 0: //other non-alphanumeric break; default: alert('no - '+e.charCode+' - '+e.which+' - '+e.keyCode); return false; }; } }); }); I'll grant that what I'm doing is likely over-engineering the solution but now that I'm invested in it, I'd like to know of a solution. Thanks for your help!
