Displaying the dialog box

The display of the dialog box is not a locking operation. The dialog box is displayed in the center of the page, with a DDW effect (Dim Disabled Windows).

YesNo is using the internal page named "WEBDEVYesNo". To include this page in your project:

Select "File .. New .. Page".Click among the quick access buttons. Click "Page" in the wheel that is displayed. The window for creating a new element is displayed: click "Page" then "Page".
In the "Internal Page" tab, select the internal page named "Yes/No".
Validate. The "WEBDEVYesNo" page is displayed in the editor.
Save the page by keeping its default name.

Line break in the dialog box

The CR string (Carriage Return) can be used to force a break to the next line. For example:

YesNo("The XXX form was modified." + CR + ...
"Do you want to save it before exiting?")

is equivalent to:

YesNo("The XXX form was modified.", ...
"Do you want to save it before exiting?")
