Auto Close Message Box
auto-close, c#, messagebox, timer
Solution
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);
}
Problem
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?
