Question
hi,
i have database with usernames and passwords and would like to know how i can create a login page that connects to this?
i have a form with 2 txtboxes and a button.
i have tried using an sql select statement but not sure how u would use this to read from the textboxes to the database and back again in order to confirm the username and password?
any help would be greatly appreciated
thanks

Answer
Hello Sir,

its so simple do this :

Dim Conn as new Data.OleDB.Connection
Dim Cmd as Data.OleDB.Command

Sub CheckLogin()
Conn.ConnectionString = "Your Database ConnectionString"
Conn.Open

Cmd = Conn.CreateCommand

Cmd.CommandText = "Select UserID From You_TableName Where Username='" & txtusername.text & "' AND Password='" & txtpassword.text & "'"

Dim Ds as new Data.DataSet

Ds.Load(Cmd.ExceuteReader,Data.Overwrites,"MyTable")

if Ds.Table(0).Rows.Count >0 then
Msgbox "You are logged In"
else
Msgbox "Incorrect Username or Password"
end if
End sub

thank you
