How can I capture Ctrl + Alt + K + P keys on a C# form? thanks

推荐答案

这是一个和弦，如果不记住和弦的第一个按键，你就无法检测到它.这有效:

It is a chord, you cannot detect it without memorizing having seen the first keystroke of the chord. This works:

public partial class Form1 : Form {
    public Form1() {
        InitializeComponent();
    }
    private bool prefixSeen;

    protected override bool ProcessCmdKey(ref Message msg, Keys keyData) {
        if (prefixSeen) {
            if (keyData == (Keys.Alt | Keys.Control | Keys.P)) {
                MessageBox.Show("Got it!");
            }
            prefixSeen = false;
            return true;
        }
        if (keyData == (Keys.Alt | Keys.Control | Keys.K)) {
            prefixSeen = true;
            return true;
        }
        return base.ProcessCmdKey(ref msg, keyData);
    }
}
