Continuous button?

[hostopolis]

I have an app that moves a window left, right, up or down by clicking the appropriate button. At this time, I have to repetitively click the button to move it. How can I make the button continuous, so I only have to hold the button down, and it continues to move until I let off? In addition to that, I still want the ability to move it one click at a time, as well. I searched everywhere, but haven't found anything that gives me what I'm looking for. Thanks...

You need to override the button class, and you need to fire a timer when the mouse is down to generate click events.

Excellent! *rubbing hands together, with an evil grin on my face* Now, how do I do that?

You could also just do it the easy way: Click once on the button, and then keep holding down the Enter-key on your keyboard.

There's no keyboard. This is for a touch screen.

Oh, okay :-D

I created a new windows form with a button and a rich text box. The following code produces the effect you want. Granted, you'll need to add more logic in there, but it should be enough to get your started:

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;

namespace WindowsApplication1
{
  public partial class Form1 : Form
  {
    public Form1()
    {
      InitializeComponent();

      this.m_Timer = new Timer();
      this.m_Timer.Interval = 100;
      this.m_Timer.Tick += new EventHandler(m_Timer_Tick);
    }

    private Timer m_Timer;

    private void button1_MouseDown(object sender, MouseEventArgs e)
    {
      // Kick off the timer to spawn the clicks.
      lock (this.m_Timer)
      {
        if (!this.m_Timer.Enabled)
          this.m_Timer.Start();
      }
    }

    private void button1_MouseUp(object sender, MouseEventArgs e)
    {
      // Stop the timer.
      lock (this.m_Timer)
      {
        if (this.m_Timer.Enabled)
          this.m_Timer.Stop();
      }
    }

    private void button1_Click(object sender, EventArgs e)
    {
      this.richTextBox1.Text += string.Format("Clicked - {0}{1}",
        DateTime.Now.ToLongTimeString(),
        Environment.NewLine);
    }

    private void m_Timer_Tick(object sender, EventArgs e)
    {
      this.button1_Click(this.button1, EventArgs.Empty);
    }
  }
}

Yup...that will get me headed in the right direction. Thank you very much.
