    - by julz666

  • Clearing input text feilds when clicked on in Flash (AS 2.0)

    - by rickstyphilis
    I have a problem where I want a text field that by default has the word NAME in it, to become empty when a user clicks on it. The text field has the instance name 'nam' and is inside a movie with the instance name 'input_text'. I've searched around and found samples of code where everyone keeps suggesting this: textboxinstancename.onSetFocus = function() { textboxinstancename.text = ""; }; should work. It seems to work for everyone else but me. I've tried using the following on the first frame of the 'input_text' movie with no luck: this.input_text.nam.onSetFocus = function() { this.input_text.nam.text = "" } I've tried putting this on the first frame of the scene, again with no result: _root.input_text.nam.onSetFocus = function() { _root.input_text.nam.text = "" } I've tried this in the same manner as the last respectively with both 'this' on the instance and '_root' on the scene (denoted by x): x.input_text.nam.onSetFocus = function() { if (x.input_text.nam.text == "NAME") { x.input_text.nam.text = ""; } }; Still no luck. Can anyone tell me what I might be doing wrong?

  • Ruby on Rails solution for scrubbing data of WYSIWYG editor user input

    - by Jimmy
    Hey everyone, I am working on a simple blogging type ruby on rails application and I have everything working through tinyMCE for a nice WYSIWYG editor so the user can add some simple things like images/youtube videos and lists. What I am looking for is a nice solution for blacklisting certain elements to be filtered out of the data when it is displayed. So is there a solution for this available as a gem or available to download anywhere? Thanks!

  • How to provide Input to Dialogs designed by Qt Designer

    - by GG
    Hello, I am a Qt beginner and working with Qt Designer to develop some small UI elements. I read http://doc.trolltech.com/4.5/designer-using-a-ui-file.html to use these GUI elements in my code and using multiple inheritance approach. I am introducing bookmark feature which somewhat look like http://img293.imageshack.us/img293/3041/screenshotyb.png. Now the problem I am facing is How can I show all existing bookmark folders in the drop down(say folders are in a QVector). So my main problem is how can I pass some inputs to the UI element. I think I'm clear, please let me know if further explanation is required. Sorry for adding links directly, rich formatting in my browser is not working. Thanks in advance,

  • JAVA: storing input into array

    - by Jann
    I need to write a program where the program would generate random letter and i would need to store this random character into an array char[] arrayRandom = new char[10]; for (int i = 0; i < 8; i++) { randomNumLet = (generator.nextInt(20) + 1); System.out.print(arrayRandomLetter[randomNumLet] + " "); arrayRandomLetter[randomNumLet] = arrayRandom[i]; } is there anything wrong with my code? because when i run this and printed the array i get boxes for all the values in the array and there are some letter that this line of code cannot print System.out.print(arrayRandomLetter[randomNumLet] + " "); Thanks

  • How are components properly instantiated and used in XNA 4.0?

    - by Christopher Horenstein
    I am creating a simple input component to hold on to actions and key states, and a short history of the last ten or so states. The idea is that everything that is interested in input will ask this component for the latest input, and I am wondering where I should create it. I am also wondering how I should create components that are specific to my game objects - I envision them as variables, but then how do their Update/Draw methods get called? What I'm trying to ask is, what are the best practices for adding components to the proper collections? Right now I've added my input component in the main Game class that XNA creates when everything is first initialized, saying something along the lines of this.Components.Add(new InputComponent(this)), which looks a little odd to me, and I'd still want to hang onto that reference so I can ask it things. An answer to my input component's dilemma is great, but also I'm guessing there is a right way to do this in general in XNA.

  • Android Reading from an Input stream efficiently

    - by RenegadeAndy
    Hey, I am making an HTTP get request to a website for an android application I am making. I am using a DefaultHttpClient and using HttpGet to issue the request. I get the entity response and from this obtain an InputStream object for getting the html of the page. I then cycle through the reply doing as follows: BufferedReader r = new BufferedReader(new InputStreamReader(inputStream)); String x = ""; x = r.readLine(); String total = ""; while(x!= null){ total += x; x = r.readLine(); } However this is horrendously slow. Is this inefficient? I'm not loading a big web page - www.cokezone.co.uk so the file size is not big. Is there a better way to do this? Thanks Andy

  • Handling Input with Zend Framework outside MVC

    - by Pekka
    In a classic Zend Framework MVC setup, there seems to be access to a generic _request object from within the model/view/controller instance as outlined here: $this->_request->getPost('variablename'); is this request object somehow available in a non-MVC setup as well? If yes: how would I initialize and access it?

  • How to stop input in Perl?

    - by user1472747
    First time poster and part time perl noobie. I'm making a reflex game. Here's the output - __________________________________________________________________________ Reflex game initiated. Press ENTER to begin the game, and then press ENTER after the asterisks are printed to measure your reflexes!. ************************* Your result: 0.285606 seconds. logout [Process completed] __________________________________________________________________________ There's one small problem though - There's 0-10 seconds (based on a random variable) after you press enter to start the game and before the stars are printed. During that time, if the player presses ENTER, it's logged as their reflex time. So I need a way to stop my code from reading their ENTER button before the stars are printed. The code - #!/usr/bin/perl use Time::HiRes qw(sleep); use Time::HiRes qw(gettimeofday); #random delay variable $random_number = rand(); print "Reflex game initiated. Press ENTER to begin the game, and then press ENTER after the asterisks are printed to measure your reflexes!.\n"; #begin button $begin = <>; #waits x milliseconds sleep(10*$random_number); #pre-game $start = [ Time::HiRes::gettimeofday() ]; print "\n****************************\n"; #user presses enter $stop = <>; #post game $elapsed = Time::HiRes::tv_interval($start); #delay time print print "Your result: ".$elapsed." seconds.\n";

  • How to use Scanner to accept only valid int as input

    - by John
    I'm trying to make a small program more robust and I need some help with that. Scanner kb = new Scanner(System.in); int num1; int num2 = 0; System.out.print("Enter number 1: "); num1 = kb.nextInt(); while(num2<num1) { System.out.print("Enter number 2: "); num2 = kb.nextInt(); } Number 2 has to be greater than number 1 Also I want the program to automatically check and ignore if the user enters a character instead of a number. Because right now when a user enters for example r instead of a number the program just exits.

  • Struts logic:iterate input field

    - by camilos
    I currently have the following code and the data is displayed fine. <logic:iterate name="myList" id="product" indexId="iteration" type="com.mycompany.MyBean"> <tr> <td> <bean:write name="product" property="weight"/> </td> <td> <bean:write name="product" property="sku"/> </td> <td> <bean:write name="product" property="quantity"/> </td> </tr> </logic:iterate> But now I need to make the "quantity" part modifiable. The user should be able to update that field, press submit and when its sent to the server, "myList" should automatically update with the new quantities. I've tried searching for help on this but all I keep finding is examples on how to display data only, not modify it. Any help would be appreciated.

  • Input Sanitation Best Practices

    - by Adam Driscoll
    Our team has recently been working on a logic and data layer for our database. We were not approved to utilize Entity or Linq to SQL for the data layer. It was primarily built by hand. A lot of the SQL is auto generated. An obvious down fall of this is the need to sanitize inputs prior to retrieval and insertion. What are the best methods for doing this? Searching for terms like insert, delete, etc seems like a poor way to accomplish this. Is there a better alternative?

  • How can I change my language/keyboard input language system-wide temporarily?

    - by Adam Lynch
    I currently have two languages set up; English and Dutch. The only difference is in keyboard input. The Dutch one uses the French/Belgian AZERTY layout and the English one uses the Irish/English QWERTY layout (@ = Shift+'). When a Belgian colleague needs to use my computer, I switch the language to NL (Dutch) (therefore the input to AZERTY) using the language bar, but it seems to be application-specific. (I.e: After changing the input to AZERTY for my colleague, if he then clicks on another program it switches back to QWERTY for that program). Is there a way I can quickly switch between the two comprehensively yet temporarily?

  • Overriding disabled input and textarea with CSS

    - by igluratds
    Hi, Im trying to override the grey text of a disabled input and textarea. At the moment Im only really concerned with it working in Webkit and Mozilla. At the moment Im currently using every trick in the book that I know of: input[@disabled=true], input[@disabled], button[disabled]:active, button[disabled], input[type="reset"][disabled]:active, input[type="reset"][disabled], input[type="button"][disabled]:active, input[type="button"][disabled], select[disabled] > input[type="button"], select[disabled] > input[type="button"]:active, input[type="submit"][disabled]:active, input[type="submit"][disabled],input[disabled="disabled"], input[disabled] { color: black !important; } Sure it does change the colour if I change it to something else, however when I choose black it is still greyed out a bit. Any ideas? I am using Ext JS if I can use that to manipulate it. Thanks.

  • How to install Wacom Bamboo Pen

    - by casadrya
    I have a new Wacom Bamboo Pen. I'm using Ubuntu 10.10 64bit. After googling a little bit, I checked that xserver-xorg-input-wacom was installed. I plugged in my tablet. I rebooted my computer. Nothing special happened. I opened Inkscape. The tablet didn't work. I opened Inkscape's Input devices dialog. I didn't understand anything. I tried to blindly click some options in that dialog but nothing seemed to have any effect. Same with Gimp. After googling some more I found the linuxwacom website with source code, this didn't seem to work. So... any help? As requested: lsusb Bus 005 Device 002: ID 056a:00d4 Wacom Co., Ltd dmesg | tail [ 492.961267] usb 5-1: new full speed USB device using uhci_hcd and address 3 [ 493.144862] input: Wacom Bamboo 4x5 Pen as /devices/pci0000:00/0000:00:1a.2/usb5/5-1/5-1:1.0/input/input6 [ 493.158854] input: Wacom Bamboo 4x5 Finger as /devices/pci0000:00/0000:00:1a.2/usb5/5-1/5-1:1.1/input/input7

  • Is there a standard dialog for constructing an ADO.Net connection string (that is redistributable)?

    - by rathkopf
    I want to use a standard dialog to solicit user input of an ADO.net connection string. It is trivial to do for the oledb connection string as described here: MSDN Article on MSDASC.DataLinks().Prompt I've also found examples that use Microsoft.Data.ConnectionUI.dll and MicrosoftData.ConnectionUI.Dialog.dll from VS (HOWTO: Using the Choose Data Source dialog of Visual Studio 2005 from your own code). Unfortunately these DLLs are not licensed for redistribution. Is there a standard dialog for choosing a data source that can be distributed with my application?

  • jQuery: how to find first visible input/select/textarea excluding buttons?

    - by Artem
    I tried $(":input:not(input[type=button],input[type=submit],button):visible:first") but it doesn't find anything. What is my mistake? UPD: I execute this on $(document).load() <script type="text/javascript"> $(window).load(function () { var aspForm = $("form#aspnetForm"); var firstInput = $(":input:not(input[type=button],input[type=submit],button):visible:first", aspForm); firstInput.focus(); }); </script> and in the debug I can see that firstInput is empty. UPD2: I'm in ASP.NET page running under Sharepoint. I've found so far that for some elements it does find them (for fixed ones) and for some don't. :(
