Password Check
Hej alle hjerner :DD
Har et lille problem eller to :)
Jeg har et login system som virker sådan nogenlunde, men der er hvert fald to fejl. Når jeg laver en ny bruger, tror jeg den gemmer den 3 gange, og kan ikk se hvorfor...
Og når jeg så skal logge ind , kan jeg ikk finde ud af at få sammenlignet de kodeordet med det brugernavn jeg har ...
Her er lidt af den kode som skal Checke om password er rigtigt ...
////////////////////
public void load() {
//map = (HashMap)obj.read();
list = (ArrayList) obj.read();
}
public void OkButton_actionPerformed(ActionEvent e) {
boolean PassCheck = false;
//MainMenuFrame MMF = new MainMenuFrame();
load();
String u = list.get(0).toString();
String p = list.get(1).toString();
String pp = new String(UserPassTextF.getPassword());
if (u.equalsIgnoreCase(UserNameTextF.toString()) == true) {
System.out.println("Asdad");
if (p.equalsIgnoreCase(pp) == true) PassCheck = true;
//////////
Hele koden kan hentes her :
http://grob.1go.dk/bikecpu3.rarKan godt skrive hele koden her istedet, syntes bare det er sådan lidt besværligt ...
Håber nogle vil hjælpe
