How to detect button press for 5 seconds continously and then open a new dialog window .

For WinForm class Button

Here is an outline of a solution

you would process events KeyDown and KeyUp

Also use class Timer.

Start Timer on event KeyDown.

In event TimerEvent5Secs
set bool b5SecsElapsed=true;

In event KeyUp
if( b5SecsElapsed )
  // open a new dialog window .

Subscribe to Control.KeyDown and Control.KeyUp events. On KeyDown, start a 5 second Timer. On timer firing, open the new window.

On KeyUp, stop the timer so that it won't fire.

This requirement is for a Touch screen application .I tried with mousedown and mouseup events with a timer that triggers after 5 seconds it is not working.

Im using a wpf application .

Im getting the exception the calling thread cannot access this object because a different thread owns it.

System.Timers.Timer objTim = new System.Timers.Timer(5000);
private void Button_MouseDown(object sender, System.Windows.Input.MouseButtonEventArgs e)
// TODO: Add event handler implementation here.


bool tempSignal = true;
private void Button_MouseUp(object sender, System.Windows.Input.MouseButtonEventArgs e)
tempSignal = false;
// objTim.Stop();


private void objTim_Elapsed(object sender, System.Timers.ElapsedEventArgs e)
if (tempSignal)

Because System.Timer.Timer Elapsed event doesn't fire on the Gui thread, if I remember right. Just marshall/dispatch to GUI thread or use another timer.

Yes, use System.Windows.Forms.Timer

Hi Guys,
It is working on my system.But got a problem working it on touch screen enabled screen.
Hi rajeshlokayata,

Here is a runable example - just copy to a new WindowsForms project and replace Program.cs content with the following code:

using System;
using System.Windows.Forms;

namespace OpenFormAfter5Seconds
    static class Program
        static void Main()
            // Create a test form with a button
            Form form = new Form();
            Button button = new Button();
            button.Text = "Press for 5 s";
            button.Dock = DockStyle.Fill;

            // Create a timer for meassuring the duration
            Timer timer = new Timer();
            timer.Interval = 5000; // 5 Seconds

            // Process Button MouseDown 
            button.MouseDown += delegate(object sender, MouseEventArgs mea)
                // Start the timer 

            // Process Button MouseUp 
            button.MouseUp += delegate(object sender, MouseEventArgs mea)
                // Stop the timer 

            // If Timer.Tick fires (after timer intervall has elapsed)
            timer.Tick += delegate(object sender, EventArgs e)
                // ... stop the timer - it shouldn't fire again

                // ... Open the new dialog - let's use a MessageBox here for demonstration
                MessageBox.Show(form, "You Pressed the Button for 5 Seconds!", "Dialog");

            // run the example

So in reality you would design your form in the Forms designer, attach eventhandlers to your button (MouseDown/Up or KeyDown/Up), Start the timer on ButtonDown, Stop it on ButtonUp (for the cases the user didn't hold the button for 5 Seconds), and if the timer interval has elapsed show your dialog!

Hi rajeshlokayata, Also in WPF the pattern is the same. If you don't want to use the System.Windows.Forms timer in WPF (you can! - just add reference to System.Windows.Forms dll...) Otherwise use the DispatchTimer ( which does the same for WPF. If you use any asynchron (to GUI thread) timer you have to marshall/dispatch the calls to the GUI elements - seems this is your problem - maybe read a little on thread marshalling or threading..

Hi johannesnestler,
Thanks for the update .

In a touch screen machine, On windows XP click is mouse down and mouse up event, however if you use your finger instead of the mouse, you might get a drag motion instead of the click, as when you press mouse down you finger might slightly move to the side from the initial position and you will get a drag instead of click.

At this scenario, can you please let me know the WPF button events for the same example(A window after 5 seconds of button press)
