检测超过1个未组合的修饰键（Ctrl和Alt）

Question

How to detect more than 1 moddifier keys? ( Alt & Ctrl )?

I have this working code:

Private Sub PictureBox1_MouseWheel(sender As Object, e As MouseEventArgs) Handles PictureBox1.MouseWheel
    If ModifierKeys = Keys.Control Then
        If e.Delta <> 0 Then
            PictureBox1.Width += CInt(PictureBox1.Width * e.Delta / 1000)
            PictureBox1.Height += CInt(PictureBox1.Height * e.Delta / 1000)
        end if
     end if
end sub

if i change it into:
If ModifierKeys = (Keys.Control Or Keys.Alt) Then stop working. How can i detect both keys, but not combined?

Answer 1

If ModifierKeys = Keys.Control OrElse ModifierKeys = Keys.Alt Then

那确实应该是显而易见的。
