3. Buat Form untuk koneksi , tambahkan button, lalu double klik button biar menampilkan editor untuk mengisikan code :
Tambahkan sintax dibawah :
Imports MySql.Data.MySqlClient
Public Class Form1
Dim svr As String = "localhost"
Dim uid As String = "root"
Dim pwd As String = ""
Dim db As String = "databasename"
Dim myConn As New MySqlConnection
Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
cConn.ConnectionString = "server= " + svr + "; user id=" + uid + "; password=" + pwd + "; database=" + db + ""
Try
cConn.Open()
MessageBox.Show("Koneksi berhasil")
cConn.Close()
Catch myerror As MySqlException
MessageBox.Show("Error Koneksi : " & myerror.Message)
Finally
cConn.Dispose()
End Try
End Sub
End Class
Atau bisa juga sintax seperti ini :
Imports MySql.Data.MySqlClient
Public Class Form1
Dim cConnAs New MySqlConnection
Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
cConn.ConnectionString = "server=localhost; user=root; password=; database=dbMysql; allow user variables=true"
cConn.Open()
MessageBox.Show("Koneksi berhasil")
End Sub
End Class
Jalankan tekan F5, lalu klik button1, maka hasilnya
