To create a dialog page

Question

HI,
I have a requirement that when user clicks on Search button on Search page without entering any search criteria, a new dialog page(like an alert box) should appear displaying the msg "This Search will take long time.Do you wish to continue". If user selects on Yes button on this dialog page the details screen should open with search results. If user clicks on No button on this dialog page, the search page should be displayed.
Can anyone please provide me the steps to create a dialog page and setting the page forward URLs for Yes & No buttons of Dialog Page.
Thanks.

Hi
You can use the below code for that:-
(i) Write the below code in the search button event in PFR.
          OAException mainMessage=new OAException("This Search will take long time.Do you wish to continue");
          // Note that even though we're going to make our Yes/No buttons submit a
          // form, we still need some non-null value in the constructor's Yes/No
          // URL parameters for the buttons to render, so we just pass empty
          // Strings for this.
          OADialogPage dialogPage = new OADialogPage(OAException.WARNING,
          mainMessage, null, "", "");
          // Always use Message Dictionary for any Strings you want to display.
          dialogPage.setOkButtonItemName("SearchYesButton");
           dialogPage.setOkButtonToPost(true);
          dialogPage.setNoButtonToPost(true);
          dialogPage.setPostToCallingPage(true);
          // Now set our Yes/No labels instead of the default OK/Cancel.
          dialogPage.setOkButtonLabel("Yes");
          dialogPage.setNoButtonLabel("No");
          pageContext.redirectToDialogPage(dialogPage);(ii) Now handle the Yes Button in PFR like this
      if (pageContext.getParameter("SearchYesButton") != null)
         // Handle Search here
      }AJ
