WEBDEV - Browser code

Displaying the dialog box

The dialog box does not lock other processes. The dialog box is displayed in the center of the page, with a DDW effect (Dim Disabled Windows).
YesNo uses the "WebDeVYesNo" internal page. To include this page in your project:
  1. Click in the quick access buttons.
  2. The creation window appears: click "Page" then "Page".
  3. In the "Internal Page" tab, select the internal page named "Yes/No".
  4. Validate. The "WebDeVYesNo" page appears in the editor.
  5. 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?")
You also have the ability to use the syntax of multiline strings. For example:
YesNo(
[
The XXX form has been modified.
 
Do you want to save changes before closing?
])

NO BROWSER FUNCTION AVAILABLE
Your documentation should go to trash, it is not possible to use YesNo in Browser, add a damn example, you only provide a skeletoon of the function but there are tons of users unable to use it. I never expect something from PCSOFT and I still get disapointed
