How I know when divide some number the results is decimal ?

I am new programing in java, I looking for any instruction what tell me where I divide a number and the results is a decimal number like 2.5, 4.9, etc.

> Excuse me, Mr_Evil, but I am a new programer, I try
to use that instruction, but I don't get it. Do you
have some example about that instruction. I
appreciate your efforts for me.
Thanks
This is what Mr_Evil meant:double originalValue = 0.0d;
for(int i = 0; i < 10; i++) {
originalValue += 0.1d;
// round originalValue to the closest (mathematical) integer
double roundedValue = Math.rint(originalValue);
System.out.println("Is the original value "+originalValue+
" an integer? "+(originalValue == roundedValue));; )

How to know when the JComboBox popup is about to show or hide?

Hi all,
In JDK 1.4, a new addPopupMenuListener() was added to the JComboBox component. I found out I have to use JDK 1.3, but I already wrote a lot of code around this particular capability. I am trying to figure out how to duplicate it in JDK 1.3. I need to know BEFORE and AFTER the popup is displayed. OR, is there a way with JDK 1.3 that as soon as they click the combo box, it fires an event. The thing is, as soon as they click it, I want to change the background color. When they are done selecting, I can use an ActionListener or ItemListener to find out what was selected and change the color again. My killer is trying to figure out how to know when they have selected the box. I tried adding MouseListener, PropertyChangeListener, AncestorListener. None are doing a thing when the JComboBox is first selected.
Any help would be much appreciated.
Thank you.

How to know when the PRICE AFTER DISCOUNT changed and get the value

Hi,
Everything I do to see if a value changed in the grid works except for PRICE AFTER DISCOUNT
which seems to be inaccessible.
Any idea how to know when exactly this value changed and do actions accordinly ?
Also I always get 0.00 if I try to get the value of it
This works to get in the condition of a vlaue changing but I always get 0.00 as the value of the column
if (pVal.ItemUID == "38" && pVal.ColUID == COL_DISCOUNT.ToString() && pVal.EventType == BoEventTypes.et_VALIDATE && pVal.ItemChanged == true && pVal.ActionSuccess == true)
    try
        SAPbouiCOM.Matrix Matrix = (SAPbouiCOM.Matrix)SBO_Application.Forms.ActiveForm.Items.Item("38").Specific;
        SAPbouiCOM.EditText Editor = (SAPbouiCOM.EditText)Matrix.Columns.Item(COL_DISCOUNT).Cells.Item(pVal.Row).Specific;
        SBO_Application.MessageBox("Discount changed for : " + Editor.Value + "...", 1, "Ok", "", "");
    catch (Exception ex)
        SBO_Application.MessageBox(ex.Message, 1, "Ok", "", "");
And this do not even get into the condition even tought I SEE the column PRICE AFTER DISCOUNT:
if (pVal.ItemUID == "38" && pVal.ColUID == COL_PRICEAFTERDISCOUNT.ToString() && pVal.EventType == BoEventTypes.et_VALIDATE && pVal.ItemChanged == true && pVal.ActionSuccess == true)
    try
        SAPbouiCOM.Matrix Matrix = (SAPbouiCOM.Matrix)SBO_Application.Forms.ActiveForm.Items.Item("38").Specific;
        SAPbouiCOM.EditText Editor = (SAPbouiCOM.EditText)Matrix.Columns.Item(COL_PRICEAFTERDISCOUNT).Cells.Item(pVal.Row).Specific;
        SBO_Application.MessageBox("Price after discount changed for : " + Editor.Value + "...", 1, "Ok", "", "");
     catch (Exception ex)
         SBO_Application.MessageBox(ex.Message, 1, "Ok", "", "");

just idea, maybe it will works
Create one udf in row level and set there FS based on changes on price after discount and fill value what is in price after discount. Then the validation make on this field instead of standard SAP field.

How to know when I'm doing a createInsert?

how to know when I'm doing a createInsert, this to hide a button when you run this action, I am using a task flow.
my version of jdeveloper is 12c

hi,
So you are using the createInsert as a method call in task flow. That is your form/table will be come new rows and you want to disable some button.
Your task flow might be as below
      CreateInsert---->Page.
To do so
1.) Take properties of your method call and bind the Method property to a method in a bean (bean registered in the task flow with scope view or any higher scope)
2) Call the create insert operation programmatically in that method.
3) And in that method after the createinsert ,set a boolean variable in pageFlowScope.
4)Put this variable in the disable property or visible propery of the button you wabt to hide/diable.
eg:
    public void doCreateInserOperation(){
        try {
           // Programatically invoke CreateInsert
            DCBindingContainer bindings = (DCBindingContainer)getBindingContainer();
            bindings.getOperationBinding("CreateInsert").execute();
        //Set a variable in page Flow Scope
        AdfFacesContext.getCurrentInstance().getPageFlowScope().put("disableButton", true)
        } catch (Exception e) {
            e.printStackTrace();
    public BindingContainer getBindingContainer() {
        FacesContext facesContext = getFacesContext();
        Application app = facesContext.getApplication();
        ExpressionFactory elFactory = app.getExpressionFactory();
        ELContext elContext = facesContext.getELContext();
        ValueExpression valueExp = elFactory.createValueExpression(elContext, "#{bindings}", Object.class);
        return (BindingContainer)valueExp.getValue(elContext);
you can access this variable in EL expression as #{pageFlowScope.disableButton}. So when your page render it will be in CreateInsert mode and the button will be disabled/hidden.
I hope this will help you.
With regards,
Gijith.

dear sir . I have bought a dell ipad under serial number DMPKQFF4F186 / UDID : 976ba8f5ba16f665bdf3b1b5ec53a172c9d65381. on 25th of dec.2013,it was packed and seems it was new after unpacking i found out it is locked.Ijust neednto know when this serial number has registered in icloud. I will grateful if you could let me this information. locking forward to your kind response. With Regards

Greetings,
I've never seen this issue, and I handle many iPads, of all versions. WiFi issues are generally local to the WiFi router - they are not all of the same quality, range, immunity to interference, etc. You have distance, building construction, and the biggie - interference.
At home, I use Apple routers, and have no issues with any of my WiFi enabled devices, computers, mobile devices, etc - even the lowly PeeCees. I have locations where I have Juniper Networks, as well as Aruba, and a few Netgears - all of them work as they should.
The cheaper routers, Linksys, D-Link, Seimens home units, and many other no name devices have caused issues of various kinds, and even connectivity.
I have no idea what Starbucks uses, but I always have a good connection, and I go there nearly every morning and get some work done, as well as play.
You could try changing channels, 2.4 to 5 Gigs, changing locations of the router. I have had to do all of these at one time or another over the many years that I have been a Network Engineer.
Good Luck - Cheers,
M.

verify & repair your startup drive
To verify & repair you file system on the startup drive, you will need to run disk utility from you installation DVD.
This article will tell you how to get to disk utility. Once in a disk utility, you can go and attempt to recover the disk.

To repair your startup drive, you will need to run disk utility from your startup DVD.
Mac OS X 10.4: About the utilities available on the Mac OS X 10.4 Install DVD

How to run disk utility from your startup DVD.
Insert your startup DVD into your reader. Power down your machine. Hold down to the c key. Power on your machine. This will bootup your startup DVD.
This will bring you to a panel asking you for your language. Pick your language.
You you come to the Install Mac OS panel. Do not install.
Click on Utilities menu item. This will give you a pulldown list of utilities.
Click on the disk utility.
You are now in disk utility. Pick your disk. Click on repair it should be on the lower right of the panel.
Once the repair completes successfully, you should update your permissions.

As an alternative, you can verify that the filesystem on the disk is correct. You will not be able to repair the file system.
I suggest that you use disk utility to verify that your startup disk is OK.
Macintosh-HD -> Applications -> Utilities -> Disk Utility
Start up disk utility. On the left pane view, you will see a list of all your disks.
Click on your startup disk.
Click on the First Aid Tab.
Click on verify.
Hopefully your disk will verify. If not, you have to boot from your installation DVD and run Disk Utility from there to attempt to repair your file-system.

Let us know when you personally receive the ICS OTA update!

We are all tired of frequently Googling for when Verizon is going to officially release the Ice Cream Sandwich OTA update for our HTC Rezounds. Please feel free to add to the discussion about the update, but most importantly, let us know when you personally receive the ICS OTA update!
...so we can stop wasting valuable hours every day just Googling...

The only reason I bought the Rezound was because the sales person assured me it would be getting the ICS update in April. LIES, LIES, LIES. Will be very glad when my contract is up!!!
That surely can't be the only reason...the HTC Rezound is a BEAST! With or without ICS.
