Hm, pocetnicko pitanjepitam se zasto mi sledeca rutina ne radi.
Htio bi da u neka unosna polja ogranicim unos brojki, slovova i ostalih karaktera
parametar te funkcije da char kod KeyPress procedure tog polja.
Nebi htio da pishem svaku proceduru za svako unosno polje, parametre koje posaljem jest Char,koji je bio pritisnut i dozvoljeni Char u array-u
nesto slicno ovom :
Code:
function TFrmOsn.VnosLe(Ch:Char;Lahko:array of Char):Char;
begin
if Ch in Lahko then
Result:=Ch
else
Result:=#0;
end;
function TFrmOsn.VnosLe(Ch:Char;Lahko:array of Char):Char;
begin
if Ch in Lahko then
Result:=Ch
else
Result:=#0;
end;
kod unosnog polja kod KeyPress bi recimo dao
Code:
VnosLe(Key,[#8,#13,#44..#57,#127]);
VnosLe(Key,[#8,#13,#44..#57,#127]);
greska se javi kod funkcije (Ch in Lahko):
[Error] Osn.pas(131): Operator not applicable to this operand type
kako to rijeshiti ?
hvala unaprijed ...
