Jdbc/findPanel cancel button?

As mentioned a while back, there is a CallableStatement.cancel() that will abort a query if called from a separate thread.
Two questions:
1. Is there a similar critter that can be set up for RowsetInfo? There's an executeQuery() but I don't see a cancel()? ( For example, if a user specifies a FindPanel criteria that may take minutes, and wants to abort in mid-stream? )
2. If I do a cancel() for a jdbc CallableStatement, it must come from a separate thread. Does anyone have a simple code segment that shows how to set a up Swing jbutton that can cancel a jdbc call based on another Swing jbutton in the same frame? ( Or do I need to set up some sorta separate frame? ) Obviously, I'm having a problem where the CANCEL button is ignored while the query is going. ( And last but not least... how do clear the state, since I keep on getting a "java.sql.SQLException: ORA-01013: user requested cancel of current operation" after the CANCEL does kick in, on supsequent queries?
TIA

Multithreaded Swing and a "Cancel Button"

I have a Swing-based app that runs some lengthy JDBC queries. Currently when the user hits the "Run Query" button a small dialog pops up to say that the process is running, please wait, etc. I'd like to add a working Cancel button to that dialog that will allow the user to stop that query before it finnishes.
From what I've been able to learn so far it seems I should use one of the SwingUtilities methods such as invokeAndWait or invokeLater. I'm not sure which one would be more appropriate for my situation though.
I'm also having trouble thinking of an elegant way (or not-so elegant if that's the only way) to have the cancel button event communicate with the DB Query thread to let it know that the process should be stopped. Detailed explanations or examples would be welcome.
Mike

You will not need to use the SwingUtilities methods. Those are when you want to update the GUI from a different thread. In your case, you want to update a class running in a non-gui thread from the GUI thread. Not a problem.
You will want to create a Runnable class that runs your query. Run that class on another thread when the query is executed. There will need to be some public 'cancel' method in that class that can be called when you want that object to cancel whatever operation it is doing. Simply call that 'cancel' method from your dialog button's action when the user hits the cancel button.
Now, how your query class handles the cancel method is the main problem. The api way of doing this would be to call the Statement.cancel() method on the statement object that is performing the query. But how (or if) that method works depends on the jdbc driver & database, hopefully yours supports it. :-)

How to stay back on same section of a report after pressing cancel button

Hi,
How we can stay back on a same section of a report page when I press Cancel button or Apply Changes button from linked Data Entry Form. For instance if I have a 200 rows in a report and I scroll down to 80th row and press Edit button when called a data entry form. Now when I press Cancel it again re-load the report from the start of the page.
Any idea!
Thanks
Sabahat

Hi Sajid,
Thanks for reply.
I have used RETURN statement like below.
SUBMIT RFWT0010 WITH vendor       = 'X'
                 WITH i_lifnr IN i_lifnr
                 WITH i_bukrs IN i_kunnr
                 WITH test         = 'X'
                  AND RETURN.
The output of RFWT0010 is displayed. but on pressing "back" button on toolbar, the flow is coming back from RFWT0010 to calling report. I want that On pressing ENTER button of keyboard. The flow should come back to calling report.

How to change the behaviour of the Cancel-Button of SSO-Login-Page (Forms)?

Hi Folks,
we use SSO-Login to authenticate users using Forms. How do I change the URL which is opened when a user clicks on the cancel button on the SSO Login page?
In the formsweg.cfg file there is a parameter named ssoCancelUrl, but if I define it, it doesn't work anyway. Seems like it has something to do with ssoDynamicResourceCreate, but I don't exactly understand what.
Can't I simply change the URL which is opened (globally), when a user hits the cancel button on any SSO-Loginpage.
Thanks in advance.
Regards.

Exactly this does not work! Please watch my settings:
Global Setting in formsweb.cfg
# Single Sign-On OID configuration parameter: indicates whether we allow
# dynamic resource creation if the resource is not yet created in the OID.
ssoDynamicResourceCreate=false
# Single Sign-On parameter: URL to redirect to if ssoDynamicResourceCreate=false
ssoErrorUrl=
# Single Sign-On parameter: Cancel URL for the dynamic resource creation DAS page.
ssoCancelUrl=
# Single Sign-On parameter: indicates whether the url is protected in which
# case mod_osso will be given control for authentication or continue in
# the FormsServlet if not. It is false by default. Set it to true in an
# application-specific section to enable Single Sign-On for that application.
ssoMode=false
App-Specific settings in formsweb.cfg
[proz]
envFile=proz.env
form=proz.fmx
title=proz
separateFrame=true
width=1280
height=960
ssoMode=true
ssoDynamicResourceCreate=false
ssoCancelURL=http://machinename:port/zugangsportal/
otherparams=useSDI=yes P_SERVER_URL=machinename:port P_REP_SERVERNAME=machinename_proz ZP_TARGET_ID=%ZP_TARGET_ID%
When I now access http://machinename:port/forms/frmservlet?config=proz I got redirected to the SSO-Login-Page but the Cancel-Button still links to Middletier Home. Why?

<li>Change Cancel Button in page 6 so that it submits.
<li>If u have conditions on that delete PLSQL process, make sure that it runs when CANCEL button is pressed also. If it is unconditional, let it be.
<li>Add a branch for the Cancel button which redirect to page 4
So effectivelly instead of *[CANCEL] -> [Redirect to page 4]* , it becomes *[CANCEL] -> [SUBMIT] -> [DELETE PROCESS] -> [Branch: redirect to page 4]*

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:

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.

Data loss popup for cancel button on overview page

Hi Experts,
Data loss popup generally appears on UI, when i try to navigate with out saving the changes. This is a standard SAP behaviour.
But, i come across the requirement where this data loss popup should also appear on clicking the 'Cancel' button on overview page on UI.
I understood that, this popup will be triggered by the methods ON_BEFORE_WA_CONTENT_CHANGE & IF_BSP_WD_EVENT_HANDLER~HANDLE_EVENT of the window impl class.
Please suggest how can i make this popup work in case of Cancel button as well.
Thanks....

Hi bkvs,
Usually when you click the "Cancel" button that means you don't want to save your entry... hence displaying the dataloss popup doesn't make really sense to me. However, you may want the user to confirm that he really wants to cancel.
So I would suggest to redefine the EH_ON_CANCEL method of your view, to display a simple confirmation popup before you actually cancel everything. This wiki will show you how to do it:

Popup with text area & ok/cancel button

Hi all,
My requirement is to display a popup with a text area in editable mode along with 'Confirm' and 'Cancel' button. If the user changes the text, and presses the 'CONFIRM' the text is to be saved in DB.
How do i implement this? Should i use a FM or modal dialog box?

You can use simple modal dialog box ..
using below syntax :
CALL SCREEN 1100 STARTING AT 1 1.
Select modal dialog box ( Screen type).

Blank row added after cancel button on create page

Hi All,
I have a create item page where I insert items into the item table in the database.
On press of the cancel button on this create page, the control reaches a itemlist page with my old search criteria and result but with a new blank row added to it.
Anybody know what's wrong?

Sorry, I misunderstood your previous question. When the cancel button is pressed. I am using pageContext.forwardImmediately with parameters to forward back to my search page. Then in the search page controller I call the AM initQuery method to run the query. My initQuery method has the following code,
StringBuffer whereClause = new StringBuffer(200);
Vector parameters = new Vector(3);
int clauseCount = 0;
int bindCount = 0;
setWhereClauseParams(null);
if ((Program != null) && (!("".equals(Program.trim()))))
whereClause.append("PROGRAM = :");
whereClause.append(++bindCount);
parameters.addElement(Program);
clauseCount++;
if ((PId != null) && (!("".equals(PId.trim()))))
Number PIdNum = null;
try
PIdNum = new Number(PId);
catch(Exception e)
throw new OAException("AK", "FWK_TBX_INVALID_EMP_NUMBER");
if (bindCount > 0)
whereClause.append(" AND (P_ID = :");
else
whereClause.append(" (P_ID = :");
whereClause.append(++bindCount);
whereClause.append(")");
parameters.addElement(PIdNum);
clauseCount++;
setWhereClause(whereClause.toString());
if (bindCount > 0)
Object[] params = new Object[bindCount];
parameters.copyInto(params);
setWhereClauseParams(params);
executeQuery();
