Question

VB有三个复选框，任意选中两个后另一个变灰暗不能选

如图，我想选中任意两个复选框后，第三个变暗不能选，并且对应的text文本也随着check的选中可见或不可见

Answer 1

用循环判断.

你建立的3个复选框和3个text都建立成数组控件.才容易处理/

Private Sub Check1_Click(Index As Integer)
    For i = 0 To 2
     If Check1(i).Value = 1 Then
         a = a + 1
         If a = 2 Then
            For x = 0 To 2
                If Check1(x).Value <> 1 Then
                    Check1(x).Enabled = False
                    Text1(x).Enabled = False
                End If
            Next
         End If
     End If
     If a < 2 Then
        Check1(i).Enabled = True
        Text1(i).Enabled = True
    End If
    Next
End Sub

Check2.Enabled = False
Text2.Enabled = False
End If
If Check2.Value = 0 And Check3.Value = 0 Or Check1.Value = 0 And Check3.Value = 0 Or Check1.Value = 0 And Check2.Value = 0 Then
Check3.Enabled = True
Text2.Enabled = True

End If
End Sub
