arkadaşalr lütfen yardım edin yoksa dersten kalacağım

[roksan]

Peki problem nedir ?

[s_kurt]

problem bu yukarıda ekte resim var orada incelerseniz isim soyisim not bunların bağlantısıı yapamıyorum yani bağlantıyı yapıp sağ taraftaki tezt alanına kayır-t değimde kayıt sil dediğimde de silinmesi bunlar

[roksan]

Bu sistemi hazırlarken hangi aşamada sorun yaşıyorsunuz, sağ taraftaki list'e element nasıl eklerim diye mi soruyorsunuz yoksa metin kutularının içindeki bilgilere nasıl erişebilirim diye mi soruyorsunuz, birşeyler yazmışsınız ancak neticede sorunuzu yazmamışsınız.

[s_kurt]

hocam sorum şimdi şu ben bu sistemi olusturdum ya bu kutulara yazı yazdığımda sağ taraftaki kısıma alttaki kayıt butonuna bastığımda kayıt etmesini istiyorum sil butonuna tıkladığımda da silmesini istiyorum


işte bu yazılımı gerceklestiremedim


Tasarımı yaptım sadece başka herhangi bir olay yok yani ad+soyad+not bunları bağlayıp sağ daki text kısıma kayıt ve sil olayı ...

Üstad cok saol allah razı olsun emek verip bana bir seyler bulmussun bu tarz benimki yanlız bir sorum olacak bu yazılım jbiulder 2007 mi bende eski versiyonu var
sorun olurmu

[roksan]

Bunlar Java kodları, ide farketmez, kodları inceleyip kendi formunuza uyarlayabilirsiniz...

Eğer ödevi hazırlarken JBuilder kullanmanız konusunda bir durum yoksa Eclipse'i öneririm...
