Hi All,
I have a login form connecting to a SQL Database but when the OnClick event fires, nothing occurs. I now that it is sorta working because if the user name / password fields are left blank, an error message is displayed
Code:Private Sub OK_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles OK.Click If UsernameTextBox.TextLength > 1 And UsernameTextBox.TextLength > 1 Then Try Dim connStr As String = ConfigurationManager.ConnectionStrings("CRM.NET.My.MySettings.CRMConnectionString").ConnectionString Dim SQL As String = "SELECT UserID, Password FROM tblUsers WHERE UserID = '" & UsernameTextBox.Text & "' AND Password = '" & PasswordTextBox.Text & "'" Dim myCommand As New SqlCommand(SQL, New SqlConnection(connStr)) myCommand.Connection.Open() Dim dr As SqlDataReader dr = myCommand.ExecuteReader() If Not dr.Read() Then MessageBox.Show("Login Failed") Else Dim Form1 As New Form1 Form1.Show() End If Catch ex As Exception End Try Else MessageBox.Show("Username and Password Must Be Entered") End If End Sub
