Что не так с моим последним оператором if, который проверяет ничью в крестики-нолики? Могу ли я использовать цикл?

Я пытаюсь проверить, есть ли ничья в игре Tic Tac Toe. Это игра против пользователя, так что она правильно определяет победителя. У меня проблемы с моим последним утверждением if, где я пытаюсь проверить на наличие ничьих. Могу ли я получить какой-либо совет в создании цикла или если оператор, который проверяет, нет ли победителя, то это ничья. Пожалуйста помоги. Благодарю.

Это не сработает. Это не то, как работает синтаксис vb.net. Каждое утверждение должно возвращать true или false. 

If Button1.Text And Button2.Text And Button3.Text And Button4.Text And Button5.Text And Button6.Text And Button7.Text And Button8.Text And Button9.Text = "X" Or "O" Then
    MsgBox("There is a Draw")
End If

Вы должны сделать 

If (Button1.Text = "O" Or Button1.Text = "X") And
   (Button2.Text = "O" Or Button2.Text = "X") And
   (Button3.Text = "O" Or Button3.Text = "X") And
   (Button4.Text = "O" Or Button4.Text = "X") And
   (Button5.Text = "O" Or Button5.Text = "X") And
   (Button6.Text = "O" Or Button6.Text = "X") And
   (Button7.Text = "O" Or Button7.Text = "X") And
   (Button8.Text = "O" Or Button8.Text = "X") And
   (Button9.Text = "O" Or Button9.Text = "X")
    MsgBox("There is a Draw")
End If
