'Auto Close Message Box
I have this program wherein I use timer to redirect to another page. It do work but the problem is when I click cancel button a messagebox will appear and when the user will not click on it and the timer ticks, messagebox didn't close. How can I automatically close the message box??
this is what it looks like..
and here is the code I used to redirect the page
DispatcherTimer sessionTimer = new DispatcherTimer();
public CashDepositAccount()
{
InitializeComponent();
con = new SqlConnection(ConfigurationManager.ConnectionStrings["kiosk_dbConnectionString1"].ConnectionString);
con.Open();
SqlCommand cmd1 = new SqlCommand("Select idle From [dbo].[Idle]", con);
idle = Convert.ToInt32(cmd1.ExecuteScalar());
InputManager.Current.PreProcessInput += Activity;
activityTimer = new DispatcherTimer
{
Interval = TimeSpan.FromMinutes(idle),
IsEnabled = true
};
activityTimer.Tick += Inactivity;
}
#region
void Inactivity(object sender, EventArgs e)
{
navigate = "Home";
Application.Current.Properties["navigate"] = navigate;
}
void Activity(object sender, PreProcessInputEventArgs e)
{
activityTimer.Stop();
activityTimer.Start();
}
How can I close the message box when I redirect to the main page when Timer ticks?

I've used this code to Close a messagebox without creating a new form. It do works fine for me. Might help you guys also. I got it from Close a MessageBox after several seconds
private void btnOK_Click(object sender, RoutedEventArgs e)
{
AutoClosingMessageBox.Show("Wrong Input.", "LMS", 5000);
}
public class AutoClosingMessageBox
{
System.Threading.Timer _timeoutTimer;
string _caption;
AutoClosingMessageBox(string text, string caption, int timeout)
{
_caption = caption;
_timeoutTimer = new System.Threading.Timer(OnTimerElapsed,
null, timeout, System.Threading.Timeout.Infinite);
MessageBox.Show(text, caption);
}
public static void Show(string text, string caption, int timeout)
{
new AutoClosingMessageBox(text, caption, timeout);
}
void OnTimerElapsed(object state)
{
IntPtr mbWnd = FindWindow(null, _caption);
if (mbWnd != IntPtr.Zero)
SendMessage(mbWnd, WM_CLOSE, IntPtr.Zero, IntPtr.Zero);
_timeoutTimer.Dispose();
}
const int WM_CLOSE = 0x0010;
[System.Runtime.InteropServices.DllImport("user32.dll", SetLastError = true)]
static extern IntPtr FindWindow(string lpClassName, string lpWindowName);
[System.Runtime.InteropServices.DllImport("user32.dll", CharSet = System.Runtime.InteropServices.CharSet.Auto)]
static extern IntPtr SendMessage(IntPtr hWnd, UInt32 Msg, IntPtr wParam, IntPtr lParam);
}

Using AutoClosingMessageBox.Show(this, "Your Message..", 1500);
. Code is as follows:
class AutoClosingMessageBox
{
private static System.Threading.Timer Tmr;
public static void Show(Form Parent, string text, int timeout)
{
Form mbx = new Form();
Label LblMessage = new Label();
#region InitializeComponent
mbx.Size = new System.Drawing.Size(308, 185);
mbx.MaximizeBox = false;
mbx.MinimizeBox = false;
mbx.ShowIcon = false;
mbx.ShowInTaskbar = false;
mbx.ControlBox = false;
mbx.AutoScaleMode = System.Windows.Forms.AutoScaleMode.Dpi;
mbx.FormBorderStyle = FormBorderStyle.None;
mbx.StartPosition = FormStartPosition.CenterScreen;
#region Center on Parent StartPosition
if (Parent != null)
{
mbx.BackColor = Parent.BackColor;
mbx.StartPosition = FormStartPosition.Manual;
int X = Parent.Location.X + ((Parent.Width - mbx.Width) / 2);
int Y = Parent.Location.Y + ((Parent.Height - mbx.Height) / 2);
mbx.Location = new System.Drawing.Point(X, Y);
}
#endregion
//
//LblMessage
//
LblMessage.Location = new System.Drawing.Point(12, 23);
LblMessage.AutoSize = false;
LblMessage.TextAlign = System.Drawing.ContentAlignment.MiddleCenter;
LblMessage.Font = new System.Drawing.Font("Microsoft Sans Serif", 9.75F, System.Drawing.FontStyle.Regular, System.Drawing.GraphicsUnit.Point, ((byte)(162)));
LblMessage.ForeColor = mbx.BackColor.ToInvert();
LblMessage.BorderStyle = BorderStyle.FixedSingle;
LblMessage.Text = text;
LblMessage.Dock = DockStyle.Fill;
mbx.Controls.Add(LblMessage);
#endregion
Tmr = new System.Threading.Timer(new System.Threading.TimerCallback(Tmr_Tick), mbx, timeout, 0);
mbx.ShowDialog();
}
private static void Tmr_Tick(object obj)
{
Tmr.Dispose();
if (obj is Form)
{
if (((Form)obj).InvokeRequired)
{
((Form)obj).Invoke(new System.Action<Form>(InvokeMbx), new object[] { ((Form)obj) });
}
else InvokeMbx((Form)obj);
}
}
private static void InvokeMbx(Form mbx)
{
mbx.Close();
}
}
