How to block the keyboard

We are developing an application that should block the keyboard for all applications running under windows. (A time limited web browser)
I know more or less how to do it on my Java Window but I need to block all the machine.
Thanks in advance.

You'll have to get into Windows system programming for that. Java is not a suitable language for that kind of project, but you can interface to suitable languages from Java using JNI.

How can I block the keyboard using the glass pane ?

I have a problem with the GlassPaneDemo from the Java Tutorial in
the
uiswing/components/example-swing
folder.
When the glass pane is visible it blocks the mouse input but the
keyboard input doesn't. For example if the glass pane is visible and
you press the F10 key, the menu will be activated. So the keyboard is
not at all blocked.
Can this problem be fixed ? I mean, to really block the keyboard
when the glass pane is visible.
Here I wrote down the specification written in the
Java Documentation at the setGlassPane method from the
RootPaneContainer interface:
The glassPane is always the first child of the rootPane and the
rootPanes layout manager ensures that it's always as big as the
rootPane. By default it's transparent and not visible. It can be
used to temporarily grab all keyboard and mouse input by adding
listeners and the making it visible. by default it's not visible.
As it may be seen, one says that the keyboard input can be blocked.
HOW ?
In hope that I resolve the problem, I have made some changes such as,
adding a key listener to the glass pane add listening to the keyboard events,
but I failed to fix the problem.
Faithfully yours,
Sarmis

Here is an example that I think will work for you.
Note the consume() call on the event object. I think that is what you're after.
import java.awt.event.*;
import java.awt.*;
import java.io.*;
import javax.swing.*;
public class Comparer extends JFrame implements ActionListener
    private GlassComponent myGlassPane;
    private JTextField myField;
    public Comparer()
        getContentPane().setLayout(new FlowLayout());
        getContentPane().add(myField = new JTextField(20));
        setGlassPane(myGlassPane = new GlassComponent());
        JButton theButton = new JButton("Glass");
        theButton.addActionListener(this);
        getContentPane().add(theButton);
        pack();
    public void actionPerformed(ActionEvent anEvent)
        myGlassPane.setVisible(true);
    public static void main(String[] args)
        new Comparer().setVisible(true);
class GlassComponent extends JComponent implements AWTEventListener
    Window myParentWindow;
    public GlassComponent()
        super();
        this.setCursor( Cursor.getPredefinedCursor(Cursor.WAIT_CURSOR) );
        setOpaque(false);
        addMouseListener( new MouseAdapter() {} );
    public void setVisible(boolean aVisibleBoolean)
        if(aVisibleBoolean)
            if(this.myParentWindow == null)
                this.myParentWindow = SwingUtilities.windowForComponent(this);
            Toolkit.getDefaultToolkit().addAWTEventListener(this, AWTEvent.KEY_EVENT_MASK);
        else
            Toolkit.getDefaultToolkit().removeAWTEventListener(this);
        super.setVisible(aVisibleBoolean);
    public void eventDispatched(AWTEvent anEvent)
        if(anEvent instanceof KeyEvent && anEvent.getSource() instanceof Component)
            if(SwingUtilities.windowForComponent( (Component)anEvent.getSource()) == this.myParentWindow )
                ((KeyEvent)anEvent).consume();

怎么取消或者屏蔽firefox的快捷键?How to cancel the keyboard shortcuts?

怎么取消或者屏蔽firefox的快捷键？我在使用其他软件时的很多快捷键都被firefox浏览器给占用了，麻烦得很，所以想取消那些快捷键。
在firefox上安装了一个shortcut的插件，也只能编辑快捷键而不能完全删除！！！！
怎么办！！！！！烦死了！！！！
严重抗议向firefox提出抗议：功能应该让我们自己来选择，而不是定死！！！！
How to cancel the keyboard shortcuts？
donnot tell me edit it！
i want to STOP it，，，，not change！！！！！！

Hello,
I will try my best to guess the issue you are reporting. I don't speak Mandarin and I used Google Translate to guess what the issue is. So, if I got that wrong, I do apologize.
You are looking to disable the Firefox shortcuts - all of them. And you want to do this because you think these shortcuts are blocking a Firefox plugin you are using. Is that correct?
您想禁用Firefox的快捷方式 - 所有这些。并且要做到这一点，因为你觉得这些快捷方式阻止你使用的是Firefox插件。这是否正确？
谢谢

How to block the creation of a Sales Orders without a linked Purchase Order

Hi. I'm trying to block the creation of a Sales Order that doesn't have a linked Purchase Order. The first thing I did is using the SBO Transaction Notification as follows:
IF @transaction_type = 'A' AND @object_type='17'
BEGIN
     IF (SELECT PoPrss FROM ORDR WHERE DocEntry = @list_of_cols_val_tab_del) = 'N'
     BEGIN
          SET @error = 1
          SET @error_message = 'Purchase Order Missing...'
     END
END
This works good. I create the Sales Order, I tick the purchase order field on the logistics tab, I click Add, and then the purchase order window appears...
Then, the problem begins... If I click the Cancel button, the purchase order is obviously not created, but the Sales Order is created.
Can someone tell me how to block the creation of the sales order If the user press the cancel button on the purchase order window (and the purchase order is not created)
As far as I can see, after clicking the add button in the sales order document, the Sales Order is created on the DB. If there's no way of blocking the creation of the Sales Order, can I avoid closing the purchase order window by the SBO_TransactionNotification? (if the purchase order has not been created)
Thanks...

Hi Yail,
I think you can't close the purchase order with the stored procedure.
Try to catch the Event when the user click on Cancel button.
So you can list the vents with event logger : https://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/docs/library/uuid/ede3be37-0e01-0010-1883-cd1b5293473e
You can block the cancel button and force the user to create the purchase order.
Hope i help you
Best regards

Again if u havent received any quantity against the PO then u can select the line items and select the block (key like) indicator or delete (dustbin like) indicator.

Hi,
The best way is to keep the materail status with deleted or blocked for puchase / sales and need to maintain in the materail master.
You cannot delete the material from material master until archiving but you can block that material for any procurement
Goto Basic data 1
X-plant matl status -
01 Blocked for procment/whse
02 Blocked for task list/BOM
10 Blocked for MRP
Select any one.
Valid from -
Here you enter valid date from which the material should be blocked.
So from this your material will be blocked for any PR/PO/any transactions related to Procurement

In word , if you press "alt" show you all the options you have . Appear numbers or letters in each options of the toolbar. So is more easy to work with the keyboard. How do you do this in pages?
Go to system preferences/language & text/input sources and check the box for Keyboard Viewer. Then select Keyboard Viewer from the "flag" menu at the top right of the screen. It will show all the special characters you can make when you press the alt and alt + shift keys.

Dear Experts
How to block the GRN, to avoid the excess inventory for the particular material.

Hi Raja
I assume that you are referring to stopping GRN of goods with resepect to the PO qty
In that case If you want to stop the GR of more goods than the quantity ordered, you can use delivery
tolerance settings in either material master data or purchase info record data.

Help! How to hide the keyboard in app...

I was bidding on an item in the free ebay App (provided by Ebay v 1.6.1 and the keyboard would not hide and I could not place a second bid. I had made one successful bid and then on a second bid (about 2 minutes later) the keyboard would not go away and I could not submit the bid - only enter a dollar value. It was beyond frustrating watching the time tick down and not being able to place a bid.
Please someone tell me how to hide the keyboard. I tried everything I knew how - tapping the screen, shaking the iphone, exiting out and coming back in and refreshing the app. Nothing would get the keyboard to go away and allow me to touch the submit bid button.
Thanks in advance and SORRY in advance if this is in the wrong forum!

Well the ability of how the keyboard shows and hides is a function of what the developer of the app made. Sounds like a bug in their program or just bad usability.
This is a topic to discuss with eBay as they developed the app. Their code has to control how things happen. Normally leaving a field to type in will make it go away, but if they didn't provide a way to leave focus, then that is a usability issue on their part.

I can't find the keyboard by using iMessage, but I can by using email or whatsapp? How I reset the keyboard on iMessage?

Did you tap in the box at the bottom of iMessage?
If you did and no keyboard is showing: Do a reset
Reset: Hold down the Sleep/Wake button and the Home button at the same time for at least ten seconds, until the Apple logo appears. Note: You will not lose any data
If that didn't helped, double tap Home button, delete the Message app and reset again.

How to block the BP

Hi all,
how to block the particuler bp?
thanks.

Hello,
Use T-Code 'BP'. Under status tabstrip, you select the check box 'Central Block'. This shall block few activities for the BP.
However I'd suggest to block all the contract accounts falling under a BP. This can be done using CAA2. Under General data tabstrip, update the 'Posting lock'. This shall block all the activities for a contract account.
Hope this helps

Points!

How to open the Keyboard

I want to add more ram but dont know how to open the keyboard.

Is your PB Aluminum? I ask because you posted your question in the Aluminum PB forums. If so, you don't install RAM from under the keyboard. You turn the computer over and unscrew the center mounted plate.
If it's Titanium, instructions are here: http://docs.info.apple.com/article.html?artnum=26245
