Detecting Maximum Touch Count

In order to get the maximum touch count capability on the system, you can use the C1TouchEventProvider.MaximumTouches static property. You can detect Windows 8 and Windows Server 2012 by using the IsWindows8 function and then you can show a message to the users whether or not the multi-touch is supported like in the following code:

[C#]

using C1.Win.TouchToolKit;

// Returns true if the OS is Windows 8, Windows Server 2012 or newer. Otherwise false.
private static bool IsWindows8()
{
  if (Environment.OSVersion.Version.Major >= 6 && Environment.OSVersion.Version.Minor >= 2) return true;
  return false;
}

private void button1_Click(object sender, EventArgs e)
{
  if (C1TouchEventProvider.MaximunTouches < 2 || IsWindows8() == false)
  {
    MessageBox.Show("This is Unsupported environment.");
  }
  else
  {
    MessageBox.Show("This is Supported environment.");
  }
}

[Visual Basic]

Imports C1.Win.TouchToolKit

' Returns true if the OS is Windows 8, Windows Server 2012 or newer. Otherwise false.
Private Shared Function IsWindows8() As Boolean
  If Environment.OSVersion.Version.Major >= 6 AndAlso Environment.OSVersion.Version.Minor >= 2 Then Return True
  Return False
End Function

Private Sub Button1_Click(sender As System.Object, e As System.EventArgs) Handles Button1.Click
  If C1TouchEventProvider.MaximunTouches < 2 AndAlso IsWindows8() = False Then
    MessageBox.Show("This is Unsupported environment.")
  Else
    MessageBox.Show("This is Supported environment.")
  End If
End Sub
