隐藏所有打开的表单，包括DialogForms

Question

我如何hide所有打开的表单，包括所有打开的dialog forms到NotifyIcon？

我目前使用

隐藏主窗体

        Me.Hide()
        NotifyIcon.Visible = True
        NotifyIcon.ShowBalloonTip(1, "WinVault", "You've been lockout due to innactivity", ToolTipIcon.Info)

让表单重新显示

Private Sub NotifyIcon_MouseDoubleClick(sender As System.Object, e As System.Windows.Forms.MouseEventArgs) Handles NotifyIcon.MouseDoubleClick
    Me.Show()
End Sub

我希望所有打开的表单（包括minimize

中NotifyIcon的对话框表单

使用Form.ShowDialog

显示对话框表单
