Just a detail : I would have write (writen ?) : "is assigned a value". The
'new'
value can be the same as the 'old' one and _assign is fired.
In the _assign method, VFP only deals with the property value; so no refresh,
no ...
Here are an example showing a 'feature' in VFP. Both properties annee_scolaire
and lettre_anne contains the current year. One in numeric format, the other in
caracter mode ("A"=2000, "B"=2001, ....). I f the value of annee_scolaire is
changed, the value of lettre_anne is changed too but there is NO infernal loop
...
PROTECTED PROCEDURE annee_scolaire_ASSIGN
LPARAMETERS pnannee
LOCAL lnannee
This.annee_scolaire = m.pnannee
lnannee = MOD(m.pnannee - m.go_param.annee_de_base, 36)
This.lettre_annee = CHR(IIF(BETWEEN(m.lnannee, 0, 26), 65, 22) +
m.lnannee)
&& 22=48-26
ENDPROC
PROTECTED PROCEDURE lettre_annee_ASSIGN
LPARAMETERS pclettre
This.lettre_annee = m.pclettre
This.annee_scolaire = m.go_param.annee_de_base - ;
IIF(BETWEEN(m.pclettre, "A", "Z"), 65, 22) + ASC(m.pclettre) && 22=48-26
ENDPROC
