Netzwerkkennwort dialog anzeigen

[NicoDE]

Zitat von DaFox:

Aber was machst bei Windows < XP?

Keine Ahnung.
Ich kenne in der Richtung nur noch den 'Xxx auswählen'-Dialog (die objsel.dll ruft den 'Netzwerkkennwort eingeben'-Dialog auf... vielleicht gibt's ja ein Flag um das selbst anzeigen zu lassen... MSDN/Google/Mathias).

Delphi-Quellcode:

uses
  ActiveX, ObjSel;
