Record Keypress events of Virtual Keyboard in Iphone
Hi. I am working on an IOS eng language dictionary and I need to record keypress events of virtual keyboard so that I can provide users with a dropdownlist (like an autocomplete) of words. I have done it through value changed event of UITextField but I am not getting anywhere with this. Is there any solution?

The iPhone Virtual Keyboard Frustrations
I am growing frustrated with my iPhone virtual keyboard. Switching to a non-physical keyboard back in 2007 was a big step for me but I ended adapting to it pretty fast and actually found myself to be comfortable with it very fast. I, however, am starting to reconsider this as there are more and more viable options to the iPhone becoming available (think: Android!). I use 3 different languages and hence 3 different international keyboards on my iPhone on a daily basis and I must say that things are getting messier and messier. Although I have gone through the trouble of resetting my custom dictionaries many times, it seems that my French keyboard cannot spell "après" properly, it keeps auto-correcting it to "Apres" every time I type it. I tried many "tricks" but none solved this problem. I was even able to replicate this issue on other iPhones using a multiple international keyboard setup. In addition, I must say that the process of switching from one language to another is cumbersome to say the least. I'm really getting tired of typing something in English only to realize that I was using the Portuguese keyboard and that my first 5 words have already been auto-corrected to Portuguese.
Apple really needs to solve this problem. What they should do, in my opinion, is allow the iPhone to use multiple languages at the same time and try and figure out which one the user is using after the first or four or five words they have typed.I find it really easy to switch between languages. All it takes is one or two tabs on the globe icon and you're set. I don't think it's a big issue. Also, you can easily tell what language you are currently on by the keyboard layout and the spelling on the space bar.
I've tried Android phones with physical keyboards and I've found typing to be a hassle on them. iPhone is the easiest mobile phone to type on. Just my personal opinion. -
When I record calendar events on my iphone or ipad I use a 24 clock, which is the basis on which my business runs. I cannot do the same on my Macbook, which is very frustrating and counter-intuitive (i.e. using am/pm). I asked my Apple support here in South Africa. The rep' said he could not answer immediately but would get back to me. I'm still waiting. Surely this is not a 'big' or 'unusual' problem?
I get 24hr everywhere not just in the dialog box
Here's a calendar entry
But I am not sure why you don't, let me put out a call for assisitance, -
Will I-Tech Virtual Keyboard work with iPhone 3G??
Hi, I was wondering if the I-Tech Virtual Keyboard (http://www.virtual-laser-keyboard.com/) would work with the iPhone 3G. Thanks!
I went to use the MMS App I downloaded for receiving pics etc... I got a message from Apple saying it is incompatible with OS 3.0 and if I wanted to continue using it, then download 3.0 later. Right! I will get rid of MMS and get 3.0!

iPhone virtual keyboard ***** big time!!! Is there anyway to turn off the annoying auto spell checker? I don't have a fat finger, the keyboard is too f*cking small! Couldn't Apple design it so you can text it from side ways to make the keys bigger? DUH !!!

How do I implement a virtual keyboard? I will compensate for assistance.
I have created a simple Adobe Air Windowed Application. The application uses the mx:HTML controls to load a web page inside my application. I have tried other means to load the web page but due to formatting issue, all other methods fail to load the page correctly. Any solution will need to use the mx HTML controls.
I have added a virtual keyboard to my project. However, when I enter a text field and then select a key on the virtual keyboard, I lose focus on the text field.
I understand the concept of event listeners and using a variable to store the text field id and using a focus event to gain the id of the text field. However, I am not a programmer by no means and this is way above my head. I am looking for someone to spend 30 or 60 minutes adding the needed code to my project so I can use the virtual keyboard. I would be willing to send someone a gift card to their favorite restaurant as compensation.
I have included the 4 files that make up my project (File names are in read text).
Your help will be greatly appreciated.
Best regards,
Joe

Problem with Virtual Keyboard in Apple Apps?
I am using an iPad 3 and have had Numbers and Pages apps since my iPad 1. I am suddenly having a problem with the virtual keyboard covering/hiding the text box where you type. For example, in Numbers: I double tap to type something in a cell and the keyboard comes up but the text box where it shows what you are typing is behind the keyboard. I haven't seen anyone else mention this problem. I have tried it both in landscape and letter orientation. I have deleted the app from my iPad and reinstalled it but that doesn't change anything. This is also happening in these apps on my iPhone 5. This started happening after the last OS upgrade. Anyone have any ideas? Is anyone else experiencing this problem?
No, I haven't seen that on iOS 6.
Have you tried restarting or resetting your iPad?
Restart: Press On/Off button until the Slide to Power Off slider appears, select Slide to Power Off and, after the iPad shuts down, then press the On/Off button until the Apple logo appears.
Reset: Press the Home and On/Off buttons at the same time and hold them until the Apple logo appears (about 10 seconds). Ignore the "Slide to power off". -
Disable / Remove Control Key From Pop-Up Virtual Keyboard
Hello. I am setting up a kiosk system using Microsoft Surface tablets. I wish to use the win8 virtual keyboard along with chrome in kiosk mode to run a web app. I am trying to edit the Keyboard Mapping in registry, which works with the physical keyboard
but not with the virtual one. All I need to do is disable the control key so users can't do anything with browser shortcuts. Also, I can't just disable them in JS because the browser captures them before they even reach the js engine.
Thanks!Hi,
On Screen Keyboard is one application that is used to simulate the keyboard to send the Key Events to system. It is not a physical keyboard but a built-in tool,
After a lot of research, I am afraid there isn’t a solid way of disabling the Windows key on virtual keyboard, including the control key.
Besides, Kiosk mode is available for Internet Explorer according to the link below, and it is available for Internet Explorer 11 after a test:
http://support.microsoft.com/kb/154780
Another thing is, it fails to start the Kiosk mode with Chrome after remove Internet Explorer from the control panel, I tried with a test.

Hi everyone
I have a problem with my VI. My VI reproduces an interface with a
keyboard that the user has to use to fill the various boxes at the
interface. At the moment, I can write all the information on a single
string, the "Value in" and save it. This solution is ok but honestly I
want to improve it for two reasons:
1) my output is a single string with all the data typed. I want to
save these data in a file but because it is a string, I need to to split
it and this operation requires that the various voices are separated by
a particular character like a comma (not a good solution)
2) I have to add another string close to the "Value in" to indicate the required data to the user.
My idea, maybe I am sking the moon, is that the user can introduce
the data moving freely between the boxes. When all the data have been
introduced, click the Ok button, close the VI and save these data in a
file as combination of strings.
Another possible solution should be to use my VI and modify it in
order that the user digits the first raw of data, clicks Enter and can
visualize this data in a separate string. Digits the second raw, clicks
Enter, visualizes this data in another separate string and so on. After
the last raw, clicks Enter, visualizes the data and closes the VI
pushing the OK button. In this way, all the data visulaized in the
separated strings can be saved easily in a file.
Any suggestions and/or help?

Virtual keyboard.vi 47 KBKudos for the cool looking vi!
I have to think about your question a little bit but I do have a couple comments. This would be a perfect XControl. I have never created an XControl but maybe this would be a good one to practice with.
In the meantime I did have a comment on how you are detecting the keypress. There are a million ways to do it and there is nothing wrong with your technique. But your technique is just a lot of development work. See the attached modification that uses search array instead of a case structure with 50 frames.
This part of your program would be perfect for a subvi and your keyboard cluster should be a strict typedef.
I hope you don't mind my unsolicited comments that have nothing to do with your question

Handling focus for virtual keyboard
I have a virtual keyboard in a non-modal dialog. My main application frame has multiple text component fields. I am trying to deliver key events from my virtual keyboard dialog to which ever text component last had the focus in the frame. However when the JButton is clicked in the keyboard dialog, the focus is lost in the frame and my attempt to dispatch the key event seems to go nowhere. How do I force the focus to stay/return to the last text component so it will get the key event?
An alternative might be to create an InputMethod. But I have not found any good examples of how to code an InputMethod. For example, <inputMethodContext>.createInputMethodWindow(...).
Maybe some one can point me to a good code example of this. -
JTree - How do I fire a valueChange Event from a keyPressed Event?
Hi,
I have been stumped trying to figure out how to fire a valueChange event in my JTree from a keyPressed event.
When a user changes tree node using the mouse a valueChange event fires. In my program the valueChange executes some code that must be done. I want to get my JTree to work, so that if a user is nagivating the tree using the keyboard, the code is only executed if they press the enter key.
Below is a little demo program of what I am attempting to accomplish. Any suggestions would be greating appriciated.
Thanks,
Corey

// Execute Code
jtree.addKeyListener(new KeyListener() {

System.out.println("keyTyped");
public void keyPressed(KeyEvent ke) {
System.out.println("keyPressed");
if (ke.getKeyCode() == KeyEvent.VK_ENTER)
bflag = true;
// Fire valueChanged here!
public void keyReleased(KeyEvent ke) {
System.out.println("keyReleased");}
Container c = j.getContentPane();
c.add(jtree);
j.setSize(200,200);
j.show();Try this, it works for me.
// Tree Key Listener
tree.addKeyListener(new java.awt.event.KeyAdapter() {
public void keyPressed(KeyEvent e) {
tree_KeyReleased(e);
private void tree_KeyReleased(KeyEvent e) {
try {
int keyCode = e.getKeyCode();
// Get the Tree Path
TreePath selPath = tree.getSelectionPath();
if (keyCode == e.VK_DELETE) { //KeyCode - 127
removeSelectedNode(); // Remove the node
else if (keyCode == e.VK_ADD) { // Key Code - 107
tree.expandPath(selPath); // Expand the Node
else if (keyCode == e.VK_SUBTRACT) { // Key Code 109
tree.collapsePath(selPath); // Collapse the Node
else if (keyCode == e.VK_ENTER) {
// What Ever you want to do here
