Everytime i use touchdown event in a button/rectangle or whatever it uses a lot of cpu the more objects i touch. Is there another way to make an event happen only once when i touch a object because touchdown is doing something that is constantly using cpu while i hold down. In my program i need to make something happen once when i touch an object and do another thing once when i stop touching it, to be more exact its to make a boolean true and false. Anyway here is the code
using System.Windows;
using System.Windows.Controls;
using System.Windows.Data;
using System.Windows.Documents;
using System.Windows.Input;
using System.Windows.Interop;
using System.Windows.Media;
using System.Windows.Media.Imaging;
using System.Windows.Navigation;
using System.Windows.Shapes;
namespace sendString
{
/// <summary>
/// Interaction logic for MainWindow.xaml
/// </summary>
public partial class MainWindow : Window
{
public MainWindow()
{
InitializeComponent();
Stylus.SetIsPressAndHoldEnabled(this, false);
}
private const int GWL_EXSTYLE = -20;
private const int WS_EX_NOACTIVATE = 0x08000000;
[DllImport("user32.dll")]
public static extern IntPtr SetWindowLong(IntPtr hWnd,
int nIndex,
int dwNewLong);
[DllImport("user32.dll")]
public static extern int GetWindowLong(IntPtr hWnd,
int nIndex);
protected override void OnActivated(EventArgs e)
{
base.OnActivated(e);
//Set the window style to noactivate.
WindowInteropHelper helper = new WindowInteropHelper(this);
SetWindowLong(helper.Handle, GWL_EXSTYLE,
GetWindowLong(helper.Handle, GWL_EXSTYLE) | WS_EX_NOACTIVATE);
}
private void Button_TouchDown(object sender, TouchEventArgs e)
{
Console.WriteLine("1111");
}
private void Button_TouchDown_1(object sender, TouchEventArgs e)
{
Console.WriteLine("22222");
}
}
