  • Generating the input id with an ActiveRecord model

    - by swilliams
    How do you generate an input's id attribute, given a model? For example, if I have a model of Person with a first_name attribute, the form helper prints out a textbox with this html: <input type="text" id="person_first_name" /> How can I generate that person_first_name from some other place in the code (like in a controller or some place)?

  • phone number validation with added input

    - by Rkstarcass
    I recently filled out a form and when I got to the phone number textBox I noticed some really cool things going on. As I entered my number, general phone symbols were getting added automatically. Example: I start entering my area code '555' and my input was changed to 1 (555) to test what just happened I backspaced on the ) and it quickly added it back in. So my question is, how do I get this input to happen?

  • WPF Keyboard Remapping

    - by m1dst
    Hello, I am trying to remap the input of a textbox. For example. If a user enters a N then I would like to change it to a 9. I thought it might be best to try and catch it in the PreviewKeyDown event although I will also need to process paste attempts (I can solve that bit I think). Is PreviewKeyDown a good place to start? If so, how do I send the replacement key. I know that e.Handled = true will stop the original key being processed. Thanks.

  • FancyBox Callback Keydown

    - by headShrinker
    I have been working on this code, and I can't seem to figure it out. Fancybox's callbacks don't seem to work at all. I have the keyboard bound to the pagination for this gallery. But I want to unbind the keyboard from the table when fancybox opens. When fancybox opens nothing changes.... What to do?? $(document).ready(function() { $('a.active').click(function() { var url = $(this).attr('href'); $('#ajaxTable').load(url+'/1'); return false; }); $("a.fancy").fancybox({ callbackOnStart: function() { $('a#gleft a#gright').unbind("keydown"); }, 'frameWidth': 570, 'frameHeight': 470 }) $(document).keydown(function(event) { if(event.keyCode == 37 ) { var url = $('a#gleft').attr('href'); if (url != null) { $('#ajaxTable').load(url+'/1'); $(document).unbind("keydown"); } } else if(event.keyCode == 39 ) { var url = $('a#gright').attr('href'); if (url != null) { $('#ajaxTable').load(url+'/1'); $(document).unbind("keydown"); } } }); });

  • Java Robot key activity seems to stop working while certain software is running

    - by Mike Turley
    I'm writing a Java application to automate character actions in an online game overnight (specifically, it catches fish in Final Fantasy XI). The app makes heavy use of java's Robot class both for emulating user keyboard input and for detecting color changes on certain parts of the screen. It also uses multithreading and a swing GUI. The application seems to work perfectly when I test it without the game running, just using screenshots to trigger the apps responses into notepad. But for some reason, when I actually launch FFXI and start the program, all of my keyboard and mouse manipulations just stop working altogether. The program is still running, and the Robot class is still able to read pixel colors. But Robot.keyPress, Robot.keyRelease, Robot.mouseMove, Robot.mousePress and Robot.mouseRelease all do nothing. It's the strangest thing-- to test it, I wrote a simple loop that just keeps typing letters, and focused notepad. I'd then start the game, refocus notepad, and it would do nothing. Then I'd exit the game, and it'd start working again immediately. Has anyone else come across something like this, where specific software will stop certain functions of java from working? Also, to make this more interesting-- Last year I wrote a very similar program using the same classes and programming techniques to automate healing a party in the game as they fight. Last year, this program worked perfectly. After running into these problems I dug up that old program, ran it without making any changes, and found that it too was having the same problems. The only differences between now and when it was working: I was running Windows Vista and now I'm running Windows 7, and several new Java versions as well as FFXI versions have been released. What the hell is going on? (if anyone needs to see my source code, email me at [email protected]. I'm trying to keep it to myself.)

  • How can I use ToUnicode without breaking dead key support?

    - by Cypherjb
    A similar question has already been asked, so I'm not going to waste time re-explaining it, an existing discussion can be found here: http://stackoverflow.com/questions/1964614/toascii-tounicode-in-a-keyboard-hook-destroys-dead-keys The reason I'm posting a new question however is that I seem to have come across a 'solution', but I'm not quite sure how to implement it. This blog post seems to propose a solution to the problem of ToUnicode killing dead-key support: http://blogs.msdn.com/michkap/archive/2005/01/19/355870.aspx However I'm not sure how to implement the suggested solution. A push in the right direction would be greatly appreciated. To be clear, the part I'm referring to is this: "There are two ways to work around this: 1) You can keep calling ToUnicode with the same info until it is cleared out and then call it one more time to put the state back where it was if you had never typed anything, or 2) You can load all of the keyboard info ahead of time and then when they type information you can look up in your own info cache what the keystrokes mean, without having to call APIs later." I'm not quite sure how to do either of those things (keyboards and internationalization are far from my strong point), so any help would be greatly appreciated. Thanks

  • UIAlertView choice causing resignFirstResponder to fail

    - by Chazbot
    Hi everyone. I'm having a similar issue to Anthony Chan's question, and after trying every suggested solution, I'm still stuck. Somehow, only after interacting with my UIAlertView, I'm unable to dismiss the keyboard in another view of my app. It's as though the Alert is breaking my UITextField's ability to resignFirstResponder. Below I instantiate my UIAlertView, which then calls its didDismissWIthButtonIndex method. Then, I call the showInfo method, which loads another UIViewController. UIAlertView *emailFailAlert = [[UIAlertView alloc] initWithTitle:@"Error" message:@"error message text." delegate:self cancelButtonTitle:@"Not now" otherButtonTitles:@"Settings", nil]; [emailFailAlert setTag:2]; [emailFailAlert show]; [emailFailAlert release]; Once the 'Settings' option is pressed, I'm calling this method: - (void)alertView:(UIAlertView *)alertView didDismissWithButtonIndex:(NSInteger)buttonIndex { if ([alertView tag] == 2) { if (buttonIndex == 1){ [self showInfo:nil]; } } } My showInfo method loads the other ViewController, via the code below: - (IBAction)showInfo:(id)sender { FlipsideViewController *fscontroller = [[FlipsideViewController alloc] initWithNibName:@"FlipsideView" bundle:nil]; fscontroller.delegate = self; fscontroller.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal; [self presentModalViewController:fscontroller animated:YES]; [fscontroller release]; } Upon clicking any textField in this Flipside VC, I'm unable to dismiss the keyboard as I normally can with - (BOOL)textFieldShouldReturn:(UITextField *)textField, and [textField resignFirstResponder]. I've omitted this code bc this question is getting long, but I'm happy to post if necessary. The interesting part is that if I comment out the [self showInfo:nil] call made when the button is clicked and call it by clicking a test button (outside the alertView didDismissWithButtonIndex: method), everything works fine. Any idea what's happening here? Thanks in advance!

  • Midiplayer stops playing sounds after 16 notes.

    - by user349673
    Hi. I am currently programming a Piano Keyboard editor, much like the one you can find in Cubase, Logic, Reason etc.. I have this big grid, double array new int [13][9], which makes it 13 rows, 9 columns. The first column [0-12][0] is the Keyboard, at the top there's "high C" (midi note 72) and at the bottom there's "low C" (midi note 60). That column is an array of JButtons and when you press for example "low C", note 60 is being played by the Synthesizer. I've gotten this to work pretty OK as for now, but one problem I have is that I can only play 16 notes in a row, then it's like the Synthesizer shuts down or something. Do you guys have ANY idea of what the problem is? A bit of the code: import java.awt.*; import javax.swing.*; import java.awt.event.*; import java.util.*; import javax.sound.midi.*; actionPerformed(ActionEvent ae){ for(int i = 0; i<13; i++){ if(o== instr[i]){//instr is the button array SpelaTangent(i); } } } public void SpelaTangent(int tangent){ int [] klaviatur = new int[13]; for(int i = 0; i<13; i++){ klaviatur[i] = (72-i); } try { Synthesizer synth = MidiSystem.getSynthesizer(); synth.open(); final MidiChannel[] mc = synth.getChannels(); Instrument[] instrument = synth.getDefaultSoundbank().getInstruments(); synth.loadInstrument(instrument[1]); mc[0].noteOn(klaviatur[tangent],350); mc[0].noteOff(klaviatur[tangent],350); } catch (MidiUnavailableException e) {} } Help is very much appreciated!

  • Convert Virtual Key Code to unicode string

    - by Joshua Weinberg
    I have some code I've been using to get the current keyboard layout and convert a virtual key code into a string. This works great in most situations, but I'm having trouble with some specific cases. The one that brought this to light is the accent key next to the backspace key on german QWERTZ keyboards. http://en.wikipedia.org/wiki/File:KB_Germany.svg That key generates the VK code I'd expect kVK_ANSI_Equal but when using a QWERTZ keyboard layout I get no description back. Its ending up as a dead key because its supposed to be composed with another key. Is there any way to catch these cases and do the proper conversion? My current code is below. TISInputSourceRef currentKeyboard = TISCopyCurrentKeyboardInputSource(); CFDataRef uchr = (CFDataRef)TISGetInputSourceProperty(currentKeyboard, kTISPropertyUnicodeKeyLayoutData); const UCKeyboardLayout *keyboardLayout = (const UCKeyboardLayout*)CFDataGetBytePtr(uchr); if(keyboardLayout) { UInt32 deadKeyState = 0; UniCharCount maxStringLength = 255; UniCharCount actualStringLength = 0; UniChar unicodeString[maxStringLength]; OSStatus status = UCKeyTranslate(keyboardLayout, keyCode, kUCKeyActionDown, 0, LMGetKbdType(), kUCKeyTranslateNoDeadKeysBit, &deadKeyState, maxStringLength, &actualStringLength, unicodeString); if(actualStringLength > 0 && status == noErr) return [[NSString stringWithCharacters:unicodeString length:(NSInteger)actualStringLength] uppercaseString]; }

  • Nginx + PHP - No input file specified

    - by F21
    I am running Ubuntu Desktop 12.04 with nginx 1.2.6. PHP is PHP-FPM 5.4.9. This is the relevant part of my nginx.conf: http { include mime.types; default_type application/octet-stream; sendfile on; root /www keepalive_timeout 65; server { server_name testapp.com; root /www/app/www/; index index.php index.html index.htm; location ~ \.php$ { fastcgi_intercept_errors on; fastcgi_pass 127.0.0.1:9000; fastcgi_index index.php; fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; include fastcgi_params; } } server { listen 80 default_server; index index.html index.php; location ~ \.php$ { fastcgi_intercept_errors on; fastcgi_pass 127.0.0.1:9000; fastcgi_index index.php; fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; include fastcgi_params; } } } In my hosts file, I redirect 2 domains: testapp.com and test.com to 127.0.0.1. My web files are all stored in /www. From the above settings, if I visit test.com/phpinfo.php and test.com/app/www, everything works as expected and I get output from PHP. However, if I visit testapp.com, I get the dreaded No input file specified. error. So, at this point, I pull out the log files and have a look: 2012/12/19 16:00:53 [error] 12183#0: *17 FastCGI sent in stderr: "Unable to open primary script: /www/app/www/index.php (No such file or directory)" while reading response header from upstream, client: 127.0.0.1, server: testapp.com, request: "GET / HTTP/1.1", upstream: "fastcgi://127.0.0.1:9000", host: "testapp.com" This baffles me because I have checked again and again and /www/app/www/index.php definitely exists! This is also validated by the fact that test.com/app/www/index.php works which means the file exists and the permissions are correct. Why is this happening and what are the root causes of things breaking for just the testapp.com v-host?

  • nginx, php-cgi and "No input file specified."

    - by Stephen Belanger
    I'm trying to get nginx to play nice with php-cgi, but it's not quite working how I'd like. I'm using some set variables to allow for dynamic host names--basically anything.local. I know that stuff is working because I can access static files properly, however php files don't work. I get the standard "No input file specified." error which normally occurs when the file doesn't exist, but it definitely does exist and the path is correct because I can access the static files in the same path. It could possibly be a permissions thing, but I'm not sure how that could be an issue. I'm running this on Windows under my own user account, so I think it should have permission unless php-cgi is running under a different user without me telling it to. . Here's my config; worker_processes 1; events { worker_connections 1024; } http { include mime.types; default_type application/octet-stream; sendfile on; keepalive_timeout 65; gzip on; server { # Listen for HTTP listen 80; # Match to local host names. server_name *.local; # We need to store a "cleaned" host. set $no_www $host; set $no_local $host; # Strip out www. if ($host ~* www\.(.*)) { set $no_www $1; rewrite ^(.*)$ $scheme://$no_www$1 permanent; } # Strip local for directory names. if ($no_www ~* (.*)\.local) { set $no_local $1; } # Define default path handler. location / { root ../Users/Stephen/Documents/Work/$no_local.com/hosts/main/docs; index index.php index.html index.htm; # Route non-existent paths through Kohana system router. try_files $uri $uri/ /index.php?kohana_uri=$request_uri; } # pass PHP scripts to FastCGI server listening on 127.0.0.1:9000 location ~ \.php$ { root ../Users/Stephen/Documents/Work/$no_local.com/hosts/main/docs; fastcgi_pass 127.0.0.1:9000; fastcgi_index index.php; include fastcgi.conf; } # Prevent access to system files. location ~ /\. { return 404; } location ~* ^/(modules|application|system) { return 404; } } }

  • Keyboard selecting nested li's with jquery

    - by Joel
    I have a load of nested <ul>'s and <li>'s and I would like to be able to have a hover / selected class on an <li>, and use the keyboard up and down buttons to select up and down on the <li>s.. however they are nested and need to jump across <ul>s if necessary. For instance: <ul> <li class='cat'> cat 1 <ul> <li class='hover'>item 1</li> <li>item 2</li> <li>item 3</li> <li>item 4</li> </ul> </li> <li class='cat'> cat 2 <ul> <li>item 5</li> <li>item 6</li> <li>item 7</li> <li>item 8</li> </ul> <ul class='subcat'> <li class='cat'> Cat 3 <ul> <li>item 9</li> <li>item 10</li> <li>item 11</li> <li>item 12</li> </ul> </li> </ul> </li> <li class='cat'> cat 4 <ul> <li>item 13</li> <li>item 14</li> <li>item 15</li> <li>item 16</li> </ul> </li> </ul> As I press the down key I wish the items to be selected in numerical order (they do not have numerical order IDs and sometimes some of them are hidden so they should be ignored. But it needs to go to the next <li> that isn't a category and set that as hover.

  • Title: Using Window Handle to disable Mouse clicks and Keyboard Inputs using Pinvoke c#

  • Neural Network Always Produces Same/Similar Outputs for Any Input

    - by l33tnerd
    I have a problem where I am trying to create a neural network for Tic-Tac-Toe. However, for some reason, training the neural network causes it to produce nearly the same output for any given input. I did take a look at Artificial neural networks benchmark, but my network implementation is built for neurons with the same activation function for each neuron, i.e. no constant neurons. To make sure the problem wasn't just due to my choice of training set (1218 board states and moves generated by a genetic algorithm), I tried to train the network to reproduce XOR. The logistic activation function was used. Instead of using the derivative, I multiplied the error by output*(1-output) as some sources suggested that this was equivalent to using the derivative. I can put the Haskell source on HPaste, but it's a little embarrassing to look at. The network has 3 layers: the first layer has 2 inputs and 4 outputs, the second has 4 inputs and 1 output, and the third has 1 output. Increasing to 4 neurons in the second layer didn't help, and neither did increasing to 8 outputs in the first layer. I then calculated errors, network output, bias updates, and the weight updates by hand based on http://hebb.mit.edu/courses/9.641/2002/lectures/lecture04.pdf to make sure there wasn't an error in those parts of the code (there wasn't, but I will probably do it again just to make sure). Because I am using batch training, I did not multiply by x in equation (4) there. I am adding the weight change, though http://www.faqs.org/faqs/ai-faq/neural-nets/part2/section-2.html suggests to subtract it instead. The problem persisted, even in this simplified network. For example, these are the results after 500 epochs of batch training and of incremental training. Input |Target|Output (Batch) |Output(Incremental) [1.0,1.0]|[0.0] |[0.5003781562785173]|[0.5009731800870864] [1.0,0.0]|[1.0] |[0.5003740346965251]|[0.5006347214672715] [0.0,1.0]|[1.0] |[0.5003734471544522]|[0.500589332376345] [0.0,0.0]|[0.0] |[0.5003674110937019]|[0.500095157458231] Subtracting instead of adding produces the same problem, except everything is 0.99 something instead of 0.50 something. 5000 epochs produces the same result, except the batch-trained network returns exactly 0.5 for each case. (Heck, even 10,000 epochs didn't work for batch training.) Is there anything in general that could produce this behavior? Also, I looked at the intermediate errors for incremental training, and the although the inputs of the hidden/input layers varied, the error for the output neuron was always +/-0.12. For batch training, the errors were increasing, but extremely slowly and the errors were all extremely small (x10^-7). Different initial random weights and biases made no difference, either. Note that this is a school project, so hints/guides would be more helpful. Although reinventing the wheel and making my own network (in a language I don't know well!) was a horrible idea, I felt it would be more appropriate for a school project (so I know what's going on...in theory, at least. There doesn't seem to be a computer science teacher at my school). EDIT: Two layers, an input layer of 2 inputs to 8 outputs, and an output layer of 8 inputs to 1 output, produces much the same results: 0.5+/-0.2 (or so) for each training case. I'm also playing around with pyBrain, seeing if any network structure there will work. Edit 2: I am using a learning rate of 0.1. Sorry for forgetting about that. Edit 3: Pybrain's "trainUntilConvergence" doesn't get me a fully trained network, either, but 20000 epochs does, with 16 neurons in the hidden layer. 10000 epochs and 4 neurons, not so much, but close. So, in Haskell, with the input layer having 2 inputs & 2 outputs, hidden layer with 2 inputs and 8 outputs, and output layer with 8 inputs and 1 output...I get the same problem with 10000 epochs. And with 20000 epochs. Edit 4: I ran the network by hand again based on the MIT PDF above, and the values match, so the code should be correct unless I am misunderstanding those equations. Some of my source code is at http://hpaste.org/42453/neural_network__not_working; I'm working on cleaning my code somewhat and putting it in a Github (rather than a private Bitbucket) repository. All of the relevant source code is now at https://github.com/l33tnerd/hsann.

  • Using Window Handle to disable Mouse clicks and Keyboard Inputs using P/Invoke

    - by srk
    I need to disable the Mouse Clicks, Mouse movement and Keyboard Inputs for a specific windows for a Kiosk application. Is it feasible using .NET ? I have removed the menu bar and title bar of a specific window, will that be a starting point to achieve the above requirement ? The code for removing the menu bar and title bar using window handle : #region Constants //Finds a window by class name [DllImport("USER32.DLL")] public static extern IntPtr FindWindow(string lpClassName, string lpWindowName); //Sets a window to be a child window of another window [DllImport("USER32.DLL")] public static extern IntPtr SetParent(IntPtr hWndChild, IntPtr hWndNewParent); //Sets window attributes [DllImport("USER32.DLL")] public static extern int SetWindowLong(IntPtr hWnd, int nIndex, int dwNewLong); //Gets window attributes [DllImport("USER32.DLL")] public static extern int GetWindowLong(IntPtr hWnd, int nIndex); [DllImport("user32.dll", EntryPoint = "FindWindow", SetLastError = true)] static extern IntPtr FindWindowByCaption(IntPtr ZeroOnly, string lpWindowName); [DllImport("user32.dll")] static extern IntPtr GetMenu(IntPtr hWnd); [DllImport("user32.dll")] static extern int GetMenuItemCount(IntPtr hMenu); [DllImport("user32.dll")] static extern bool DrawMenuBar(IntPtr hWnd); [DllImport("user32.dll")] static extern bool RemoveMenu(IntPtr hMenu, uint uPosition, uint uFlags); //assorted constants needed public static uint MF_BYPOSITION = 0x400; public static uint MF_REMOVE = 0x1000; public static int GWL_STYLE = -16; public static int WS_CHILD = 0x40000000; //child window public static int WS_BORDER = 0x00800000; //window with border public static int WS_DLGFRAME = 0x00400000; //window with double border but no title public static int WS_CAPTION = WS_BORDER | WS_DLGFRAME; //window with a title bar public static int WS_SYSMENU = 0x00080000; //window menu #endregion public static void WindowsReStyle() { Process[] Procs = Process.GetProcesses(); foreach (Process proc in Procs) { if (proc.ProcessName.StartsWith("notepad")) { IntPtr pFoundWindow = proc.MainWindowHandle; int style = GetWindowLong(pFoundWindow, GWL_STYLE); //get menu IntPtr HMENU = GetMenu(proc.MainWindowHandle); //get item count int count = GetMenuItemCount(HMENU); //loop & remove for (int i = 0; i < count; i++) RemoveMenu(HMENU, 0, (MF_BYPOSITION | MF_REMOVE)); //force a redraw DrawMenuBar(proc.MainWindowHandle); SetWindowLong(pFoundWindow, GWL_STYLE, (style & ~WS_SYSMENU)); SetWindowLong(pFoundWindow, GWL_STYLE, (style & ~WS_CAPTION)); } } }
