Observaciones Characteristics of dialog box - El título del cuadro de diálogo corresponde al título de la ventana (o página) actual.
- Para modificar o definir el título del cuadro de diálogo, utilice la función NextTitle.
- The message is aligned to 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 in parameter, it will be truncated.
- The icon displayed (exclamation mark) cannot be modified.
Line break in the dialog box The CR string (Carriage Return) can be used to force a break to the next line. For example:
IF OKCancel("Caution: you are going to delete this record" + CR + ... "Do you want to continue?") THEN HDelete(CUSTOMER) END
is equivalent to:
IF OKCancel("Caution: this record will be deleted", ... "Do you want to continue?") THEN HDelete(CUSTOMER) END
You also have the ability to use the syntax of multiline strings. For example:
OKCancel(
[
Caution: you are going to delete this record.
Do you want to continue?
])
