Password Hide

Друг проблем:
Как да преработя InputQuery-то така че паролата да ми се изписва в Edit-a като звездички?

Защо пък Query-to?
просто на Edit-а, в Property PasswordChar='*'

Blagodarq za syweta.
Obache wypreki tova tozi nomer nestava sys normalna forma na koqto ima edit.Tuk da mi kajete kak da se sprawq?

Сори.. не бях разбрал че е за InputQuery< и го бях написал за Edit...
а за да го видиш с Edit как става, извикай си готовите екрани на Делфи и там има Password Dialog , и ще видиш как е!


Друго си е....

Np..6te go vidq tova deto kazva6
