Answer Posted / sonj
dim qry as string = SELECT name,password FROM compare where
name = '" + txtName.text + "' AND password = '" +
txtPassword.txt + "'"
Dim ConectionString As String = "User ID=xxx;Password = yyy;
Initial Catalog='" + DataBaseName + "';Data Source=<System No>"
dim con as SqlConnection = New SqlConnection(ConectionString )
con.open
dim cmd as SqlCommand = new SqlCommand(qry,con)
dim dr as SqlDataReader = cmd.ExectueReader
if dr.HasRows = True then
messagebox.show("User ID Found")
else
messagebox.show("User ID Not Found")
end if
Above is the one example. There are various ways to validate
fox example you can write a stored procedure to validate
ID,Password and avoid SQL Injection etc.,
