Cancel button help

hi
im still fairly new to java and i was just wondering how i would go about making a cancel button for my JOptionPane boxes
also i have an array that when its searched it displays the result in JOptionPane windows, but if there are more than one result it will show it up in one then another one comes up after and displays in there to. i want them both displayed in the same box
part of my coding is here:
if (inputbox == 1){
String input2 = JOptionPane.showInputDialog("Please enter a flight number eg QF5");
for (int row = 0; row < 21; row++) {
if (Flights[row][0].equals(input2)){
JOptionPane.showMessageDialog(null,"flight " + Flights[row][0] + '\n' + "Will be leaving from " + Flights[row][3] + " and going to " + Flights[row][4] + '\n' + "Departing at: " + Flights[row][1] + " And will arrive at: " + Flights[row][2]);
}code]
i use a menu system at the start which they press a number, in this example its 1, it will take them to another box that askes them to enter a flight number which it then searches the array for. it works ok if there is only one answer but if there is more than 1 then it shows them in seperate boxes, i want them in the same box.
thank you for your time
cheers

I can't open my computer. When I type in the password an extra arrow appears facing upwards (the other one facing to the RHS) If I press either nothing happens there is a cancel button as well (which i don't need) HELP!?

I cannot open my computer> When I type in my password an extra arrow appears (facing upwards) If I press either the usual arrow (facing RHS) or the new one nothing happens.
A cancel button below the password is also present
I am getting desperate
Any ideas
Thanks

Check that your Caps lock isn't on. Maybe the light that indicates whether it is or not has stopped working. Anyway, try pressing it see if it helps.

Javascript help needed (confirmation for cancel button )

Hi guys!
I am not good at javascript but am going to improve shortly :-). Now i need very quick fix.
I'm using <html:cancel> button in Struts 1.1 and I'm using without thinking the following code:
<html:cancel onclick="bCancel=true;" >
<bean:message key="cancel.operation"/>
</html:cancel>
It is not that important though. I would like very much to alert user on possible loss of data (long multipaged form - could press mistakingly, who knows).
Would you, please post the javascript code that is needed to accomplish this - just alert and if yes - cancel, no - leave alone?
I'll really appreciate this.

Thank you for your response.
I also manage to write this. Is this correct?
<script language="JavaScript">
function ensure() {
return confirm("Are you sure that you want to cancel this operation?");
</script>
<td colspan="3" align="center">
<html:cancel onclick="bCancel=ensure();" >
<bean:message key="cancel.operation"/>
</html:cancel>
</td>

Cancel button on form of type form on a table or view

I am a newbie for apex. I am using 10g. I have created form on table emp(empno , name , salary ) . Form is of type Form on a Table or View.
Cancel & Save(Apply changes) button are not working at all. so I copied process reset page and execute on condition save button click. But still cancel button is not working. applcation has some other forms of type Form with a Report and are working properly. I have wasted 2 days on this problem.

Hi,
You can do that. If you have the branch to in the same form what you have to do use clear cache for that page. Click on the edit page, click on the cancel button in the left button section. scroll down to bottom and type the page 32 in the Clear cache field. However it is better to have branch to the report page (different page from the form).
Hope this will help.

How to stop the Flex application when user clicks on Cancel button from JS-confirm message?

Hi All,
I use the next code when a user clicks on a link:
private function clickHandler():void
      ExternalInterface.call('confirm', 'Of course you want to go to the Adobe forums!');
      navigateToURL(new URLRequest('http://forums.adobe.com'), '_self');
This will show up the javascript confimation box. But when the cancel-button is clicked, the user goes straightly to http://forums.adobe.com...
How to stop Flex performing the next code when a user clicks on the Cancel button?
Or, how to catch which button is clicked by a user in Flex?
Thanks!

I agree with Mr. Hall that using mx.controls.Alert in Flex may be a better route.
Show the Alert like this:
// show an alert with a question and yes and no choices
Alert.show( "Would you like to go to the Adobe Forums?", "Question",
     Alert.YES | Alert.NO, this, closeHandler, null, Alert.YES );
Then handle the response in the closeHandler() function:
protected function closeHandler( closeEvent:CloseEvent ):void
if( event.detail == Alert.YES )
     navigateToURL( new URLRequest('http://forums.adobe.com'), '_self' );
else if( event.detail == Alert.NO )
     // they chose no
The following documentation on Alerts may be helpful:

Let me know if that helps...

How to handle the "cancel" button and "close" icon of a popup ?

Hi,
I have a popup with "cancel button" and "close icon"(on the top right corner of the popup), I want the same operations to be performed on clicking of any of these two components.
Is there a way to handle such situation ?
I read about 2 cases to look into this but they didn't work too well for me.
1. I read about the "popcancellistener" but that listener is called whenever the popup closes, so suppose I have an "ok button" on the popup to create a record, after the record is created, the popup closes and goes into the "popcancellistener", now the question is "how do we know if it came there because of the 'ok button' or 'some other event'".
2. I even checked the "DialogListener", now I'm able to distinguish between the 'OK' and 'CANCEL' button in the dialoglistener using the "Dialog.Outcome.ok/cancel", but when a user clicks on the close icon, we do not enter the "DialogListener" at all, so in this case "how do we handle the close icon click event"
Do let me know if you need any more information from my side.
Thanks for the help in advance.

The following mechanism responds to any of the following events: <Esc> key, Close icon ('x'), Cancel button
JavaScript part:
function popupClosedListener(event){
              var source = event.getSource();
              var popupId = source.getClientId();
              var params = {};
              params['popupId'] = popupId;
              var type = "serverPopupClosed";
              var immediate = true;
              AdfCustomEvent.queue(source, type, params, immediate);
}JSF part:
         <af:popup ....>
              <af:clientListener method="popupClosedListener"
                                       type="popupClosed"/>
              <af:serverListener type="serverPopupClosed"
                                      method="#{myBean.serverPopupClosedMetod}"/>
        </af:popup>Finally, Java part:
public void serverPopupClosedMetod(ClientEvent event){
}

How do I create an input box with a cancel button that will end a loop in my script?

I have been working on a script for my client and I am having trouble getting it to work properly. I stole most of the code from the PowerShell Tip of the Week "Creating a Custom Input Box". I also took someone's code for the Show-MessageBox function.
I have slightly modified the original code with two parameters and an additional text box. The first field is for an e-mail address and the second is for an employee number.
I need to know how I can get a Do Until loop to recognize when the cancel button is pushed and break the loop and effectively end the script. The work happens at the end but perhaps I need something added/modified in the InputBox function.
I want the script to check to see if anything has been entered in the second text box. If empty it displays a message and calls the InputBox function again. Then if there is something I use elseif to check to see if it matches my RegEx (digits only). If
it doesn't match it will loop and call the InputBox function again.
This all works fine. The problem I am having is that I cannot cancel out of the form. I'd like the loop to continue until the second box matches my RegEx or Cancel is clicked. Clicking cancel doesn't break the loop. I need to know how I can stop the loop
when cancel is pressed. I've seen Stack "Overflow: PowerShell Cancel Button Stop Script" but I don't think this will work in a loop.
Any help would be awesome. As a note, I DO NOT want to use the VB Interaction stuff.

Af:dialog model-restore / cancel-button processing best practice ?

Using JDev 11.1.1.3; if I have an af:dialog running in an af:popup which contains auto-submit components (for cross-component enablement, validation etc.). My question is what are the preferred ways of discarding the model submitted changes made through popup processing if/when the af:dialog cancel button is pressed by user ? Figured that using a task flow for the content that is the popup could be an option, and using the task flow savepoint restore feature, but that looks more like database restore than model restore. I want to be able to restore the model content to the way it looked before the popup executed, without necessitating a submit to the database. How is this most commonly and best achieved ?
Thanks,

Taskflow savepoints are not database savepoints. Transactional BTF can be configured to issue automatic savepoints at TF entry and eventually to "rollback" to them at the TF exit. The internal implementation uses the ApplicationModule's passivation/activation mechanism to passivate the AM state at the TF entry and eventually to activate the AM state at the TF exit back to the passivated state at the entry. In this way it is simulated that you have not made any modifications in ADF BC, so your model layer will be restored to the state before TF entry. (Of course, you must not perform any DB commits durring the lifetime of this TF). I have used successfully this mechanism for the same goal you are asking about.
Also there are savepoints managed by the ADF Controller, but I could be of little help here because I have never used them. I suspect that this mechanism could be what you need, so you may have a look here for more details:

How to use a cancel button........

hello everyone,
i have a selection screen, from where i am calling a selection-screen as a pop-up screen. the fields i am checking on the pop-up screen will get append on the previous screen. now the problem i am facing with the cancel button.
if i am pressing the cancel button still the checked fields are getting appended.
i want to exit from the screen and want to keep the previous screen as it is. it is a simple report program.
please help me out.
thanks i advance.

I am using set screen 0. and leave screen.
but still the problem persists.
let me tell you in detail.
i am going to pop-up screen to get the fields appended on my previous screen.
if i check some checkboxes on it and click ok then according to those checked fields the corresponding select-options should come on previous screen.
because i have added set screen 0. to 'OK'.
now what i am facing is if i check some checkboxes on the pop-up and say 'CANCEL' still the program is appending the those checkboxes and appending them on the previous screen.
what i am expecting is, it should exit the pop-up screen and should maintain the previous screen as it is.
thanks

How to disable the cancel button in the ProgressMonitor

hi,
I need to know, is there any way to disable/remove the (cancel)button in the ProgressMonitor?
One more problem is,
Once i click the cancel button, isCanceled() return true, how to make it false again so that the process continue....
It is very urgently.....
please help me out.
Thanks in advance.
Regards,
Deepa Raghuraman

I don't think that's a good solution, because Cancel button itself is not disabled, so user is tempted to click it and nothing happens.
A better but dangerous solution is this:
progressMonitor = new ProgressMonitor(ProgressMonitorDemo.this,
"Running a Long Task",
"", 0, 100);
progressMonitor.setMillisToDecideToPopup(0);
progressMonitor.setMillisToPopup(0);
progressMonitor.setProgress(0);
JDialog dialog = (JDialog)progressMonitor.getAccessibleContext().getAccessibleParent();
JOptionPane pane = (JOptionPane)dialog.getContentPane().getComponent(0);
pane.setOptions(new Object[]{});Refer to the same question here [http://stackoverflow.com/questions/512151/how-do-i-disable-the-cancel-button-when-using-javax-swing-progressmonitor] .

How to change the text in the Cancel button of JFileChooser ?

Hello,
In french the standart text in the Cancel button of the JFileChooser class is "Annuler". For a good reason which will be too long to explain, I need to change it by another term.
I tried to create a super class and redefine the CANCEL_SELECTION string, but this does not work. I can't either change it directly because it has the final attribute.
Where does JFileChooser get this word from ? ( I guess it is not hard coded for multilanguage support purpose).
Any help would be appreciated
Gege

I believe the standard Look and feel implementations look in UIManager for a string called FileChooser.cancelButtonText.
Therefore you might be able to change it after you've loaded your LnF by using the following code:
UIManager.put("FileChooser.cancelButtonText", "---change me---");Note that this would change all file choosers in your application.
If you only want to update one type of file chooser you could extend, for example, MetalFileChooserUI and set its cancel button text by overriding installStrings. You'd then need to install this UI on the file chooser you want to change.
There may be an easier way to do this!
Hope this helps.

Creating a dialog box with OK and Cancel buttons without OADialogPage

Hi Experts,
i want to create a dialog box for Delete Confirmation means after clicking on delete it should pop up a small dialog box with OK/Cancel buttons
and need code for the same to handle the buttons.
i have created with OADialogPage but its showing in a complete page but i want to show those buttons in a small box.
Plz help.
THANKS IN ADVANCE.
Thanks
Raja.

Hi,
I have not tried using javascript in destination URI as suggested by Mukul.
I have tried the below code for opening a page as dialog box.
You can try it for your requirement by creating a dialog page of your own, say XXDialogPage (with OK and Cancel button)
StringBuffer l_buffer = new StringBuffer();
l_buffer.append("javascript:mywin = openWindow(top, '");
String url = "/OA_HTML/OA.jsp?page=/xx/oracle/apps/fnd/dialog/webui/OADialogPG";
OAUrl popupUrl = new OAUrl(url, OAWebBeanConstants.ADD_BREAD_CRUMB_SAVE );
String strUrl = popupUrl.createURL(pageContext);
l_buffer.append(strUrl.toString());
l_buffer.append("', 'lovWindow', {width:500, height:500},false,'dialog',null);");
pageContext.putJavaScriptFunction("SomeName",l_buffer.toString());
In dialog page's controller, you can forward it to the page onc ethe user selects OK or Cancel.
Pass the selected value back to the main page and further you can use it for deleting.
Regards.
