Features of the dialog box

  • The title of the dialog box corresponds to the title of the current window (or page).
  • To modify or define the title of dialog box, use NextTitle.
  • The message is aligned to the left.
  • The captions of buttons depend on the runtime language of Windows.
  • The maximum number of characters cannot exceed 4096. If a larger string is passed as parameter, it will be truncated.
  • The icon displayed (exclamation mark) cannot be modified.
WINDEV To customize this dialog box (and all the system dialog boxes in your application), check "Customize system windows (Info, YesNo, Confirm, Dialog)" in the "Style" tab of the project description. For more details, see Customizing dialog boxes.

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
