Saya memiliki aplikasi utama yang memiliki tombol perbatasan yang berbeda. Ini juga termasuk tombol "Einstellung". Menekan tombol ini akan menampilkan konten yang berbeda dari sebelumnya. Ini saya sadari dengan UserControl.
Sekarang Anda dapat membuat pengaturan di kontrol pengguna ini dan menyimpannya.
Penghematan ini saya lakukan di Pengaturan
dan dengan Kode
Vorschau.Properties.Settings.Default.BreiteBitmap = Int32.Parse(tbBreiteBitmap.Text);
Vorschau.Properties.Settings.Default.HoeheBitmap = Int32.Parse(tbHoeheBitmap.Text);
Vorschau.Properties.Settings.Default.AnzahlKoordinaten = Int32.Parse(tbAnzahlKoordinaten.Text);
Sekarang saya menekan tombol "Speichern". Dia menyelamatkan saya pengaturannya. Saya sekarang mengubah Kontrol Pengguna, jadi saya mengklik tombol "Vorschau" dan konten baru ditampilkan kepada saya. Kalau sekarang saya klik lagi pada "Einstellung" apakah isinya masih ada, karena sudah saya simpan.
Tapi masalahnya datang. Saya menutup aplikasi dan membukanya lagi. Sekarang saya mengklik tombol "Einstellung" di kotak teks hanya ada angka 0 di mana-mana.
Seharusnya tidak demikian, namun isinya harus berasal dari masa lalu.
Saya mengambil konten ini ketika saya memulai aplikasi. Lihat cuplikan kode.
public UCEinstellung()
{
InitializeComponent();
//Lade der Einstellungen
tbBreiteBitmap.Text = Vorschau.Properties.Settings.Default.BreiteBitmap.ToString();
tbHoeheBitmap.Text = Vorschau.Properties.Settings.Default.HoeheBitmap.ToString();
tbAnzahlKoordinaten.Text = Vorschau.Properties.Settings.Default.AnzahlKoordinaten.ToString();
}
DAN
public MainWindow()
{
InitializeComponent();
MouseDown += Window_MouseDown;
einstellung.tbBreiteBitmap.Text = Vorschau.Properties.Settings.Default.BreiteBitmap.ToString();
einstellung.tbHoeheBitmap.Text = Vorschau.Properties.Settings.Default.HoeheBitmap.ToString();
einstellung.tbAnzahlKoordinaten.Text = Vorschau.Properties.Settings.Default.AnzahlKoordinaten.ToString();
}
Sayangnya hal ini tidak berhasil. Saya harap Anda dapat memberi tahu saya di mana letak kesalahannya. Di aplikasi lain TANPA kontrol pengguna berfungsi, ini disimpan dan diambil dengan benar.
