推荐答案

好的，在阅读您的帖子后，根据我的理解，这样的事情应该可以解决问题.

Ok after reading your post and from what I can understand, something like this should do the trick.

Public Class Form1
Dim keyCombo As New List(Of Keys)({Keys.ControlKey, Keys.H, Keys.P})
Dim currentKeys As New List(Of Keys)

Private Sub Form1_KeyDown(sender As Object, e As KeyEventArgs) Handles Me.KeyDown
    currentKeys.Add(e.KeyCode)

    If currentKeys.Intersect(keyCombo).Count = keyCombo.Count Then
        MessageBox.Show("CTRL + H + P Has Been Pressed....")
        currentKeys.Clear()
    End If

End Sub

Private Sub Form1_KeyUp(sender As Object, e As KeyEventArgs) Handles Me.KeyUp
    currentKeys.Remove(e.KeyCode)
End Sub

Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load
    Me.KeyPreview = True
End Sub

End Class
