Bazı kodları direk copy paste yaparak calıstırabilirsiniz, bazilarinda componentler bulundugundan once onları olusturup kodların basında belirttigim isimleri verdikten sonra uygulamayı yapistirin, kodlar tamamen suan aktif calisan programlara aittir takıldıgınız yerde elimden geldigince yardımcı olmaya calısırım,hadi kolay gelsin

Temel Server-Client Uygulaması (Winsock Kullanımı)
'Winsock componentinin kullanımı oldukca basittir
'Bir server ve client baglantıda onemli olan 2 sey vardır
'Bunlardan birinci IP ikincisi Port Numarasıdır.
'Not: server in local portu ile clientin remote port
'degerleri aynı olmalıdır
'Bir serverin temel amacı baglantıyı dinlemek
've eger bir baglantı olursa bunu kabul etmektir
'Server icin

Baglantı Butonu altına:
'Winsock.Localport=123
Winsock1.listen

Winsock1 in connectionrequest olayı altına:
If Winsock1.State sckClosed Then Winsock1.Close
Winsock1.Accept requestID

'Bu kadar: client baglanmaya calısırsa server cevap veriyor ve
'baglantı saglanıyor.
'Simdi Client Ugulamasını yazalım bu daha kolay:

Baglan butonu altına:
winsock1.remoteport=123
winsock1.connect

'Baglantinin durumunu winsock1.state ile izleyebilirsiniz
'state degeri 0 ise hic bir islem yapılmıyor
'state degeri 2 ise dinliyor.
'state degeri 6 ise baglanıyor
'state degeri 7 ise baglandı
'state degeri 8 ve 9 hata olustu

'Baglantıyı yaptınız simdi veri transferinde bu en kolay islemdir.

'Server veri alan taraf varsayarsak
'Kodu server in winsock unun dataarrival olayı altına yazıyoruz
dim data as string
winsock1.getdata data
msgbox data

'Client Veri gonderen taraf
'Kodu istediginiz yere yazabilirsiniz (Orn: Mesaj Gonder Butonu)
dim data as string
data="Selam Visual Basic Severler"
winsock1.sendata data

'NOT: Bu arada veri transferinin yapılabilmesi icin her iki winsock
'ogesinin state degerleri 7 yani "baglandı" konumunda olmalıdır.

Temel Veritabanı Uygulaması (MSAccess icin)
Kodu yazmadan sunu soyleyeyim bu kod blogu ile componentsiz baglanti sagarsiniz yani kontrol sizdedir hangi asamada ne yapiyor takibi kolaydir cok buyuk databaselerde kullanisli degildir ama baslangıc olarak veya cok buyuk olmayan datalarda kullanabilirsiniz,
------------------------------------------------------------------------
'Bu temel uygulamayla veritabanı karmasasindan kolaylıkla
'kurtuluyoruz.
'Once tanımlamalar
'------------------------------
'General Kısmına:
Dim db As Database
Dim rst1 As Recordset
'------------------------------
'Form_Load: kısmına bu kodu yazıyoruz:
Set db = OpenDatabase("c:\belgelerim\data.mdb")
With db
Set rst1 = .OpenRecordset("MUSTERI")
End With
'-----------------------------
'Not bu basamaktan sonra basında ! isareti bulunan degerler veri tabanınizdaki tablo alti field lerini belirtiyor
'Kaydet islemi
with rst1
.addnew
!ad="Deneme Ad"
!soyad="Deneme Soyad"
!telefon="123456789"
.update
end with
'---------------------------
'Gordugunuz gibi text kutuları baglama ve data obj olmadıgı icin
'kontrol kodu yazan kisidedir. Boylece Veri Tabanını yonetmek daha
'kolaydır.
'Okuma islemi
with rst1
.movefirst
bas:
degisken1=!ad
degisken2=!soyad
degisken3=!telefon
.movenext
If Not rst1.EOF Then GoTo bas
end with
'-----------------
'Silinecek kodu bulana kadar okuma isleminin aynısı tekrarlanır
'Silinecek kayıt aktif iken
.delete
'ile silme islemi yapılır
'----------------
'Degistirme islemi aynı yeni giriste oldugu gibi degistirilecek
'kayıt aktif iken
.addnew
'yerine
.edit
'yazarız.
'---------------
'NOT : butun bu islemleri tamamladıktan sonra bunu veri tabanınıza
.update
'ile yansıtabilirsiniz.
