Menyembunyikan Jendela dengan C#[^]

Coba ini:
Menggunakan DiKeydown[^] peristiwa:

private void OnKeyDown(object sender, System.Windows.Forms.KeyEventArgs e)
{
     if (e.Shift && e.KeyCode == Keys.H) 
     {
         WindowState = FormWindowState.Minimized;
     }        
}

Menemukannya Di Sini[^]

Anda perlu terhubung ke api win32. Segera setelah Anda menyembunyikan formulir .net, acara dan pelanggan acara berhenti bekerja karena hanya ada di wadah formulir. Anda membutuhkan sesuatu seperti ini.

Sekarang daftarkan S dan H dengan Alt + Shift dengan memanggil dan meneruskan tipe panggilan balik Action.

Hubungkan Tindakan untuk panggilan balik Anda yang akan menampilkan formulir Anda atau menyembunyikannya.

Untuk menampilkan dan menyembunyikan jendela di aplikasi Windows Forms menggunakan tombol pintasan, Anda dapat menangani peristiwa KeyDown untuk mendeteksi ketika tombol pintasan ditekan. Kemudian, Anda dapat mengubah visibilitas formulir sesuai kebutuhan. Berikut adalah contoh dasar bagaimana Anda dapat mencapai hal ini:

using System;
using System.Windows.Forms;

namespace YourNamespace
{
    public partial class MainForm : Form
    {
        private bool isVisible = true; // Flag to track the visibility of the form

        public MainForm()
        {
            InitializeComponent();
            this.KeyPreview = true; // Enable key events to be captured by the form
            this.KeyDown += MainForm_KeyDown; // Subscribe to the KeyDown event
        }

        private void MainForm_KeyDown(object sender, KeyEventArgs e)
        {
            // Check if the shortcut key (e.g., Ctrl + H) is pressed
            if (e.Control && e.KeyCode == Keys.H)
            {
                // Toggle the visibility of the form
                isVisible = !isVisible;
                
                if (isVisible)
                {
                    // Show the form
                    this.Show();
                }
                else
                {
                    // Hide the form
                    this.Hide();
                }
            }
        }
    }
}

Dalam contoh ini:

Kami telah berlangganan acara KeyDown formulir di konstruktor.
Ketika tombol pintas (dalam hal ini, Ctrl + H) ditekan, event handler MainForm_KeyDown dipanggil.
Di dalam event handler, kita mengaktifkan visibilitas formulir menggunakan flag isVisible dan metode Show() dan Hide().
Pastikan untuk mengganti YourNamespace dengan namespace aplikasi Anda yang sebenarnya. Anda juga dapat mengkustomisasi kombinasi tombol pintas (Ctrl + H dalam contoh ini) dengan memodifikasi kondisi di event handler KeyDown.
