    Hi all,
    I'm Miky, I'm looking to write a script to manage input by wacom tablet in unity.
    I try to understand and integrate in my unity project the WintabDN exemple that you find here:
    http://us.wacom.com/en/developerrelations/windows/
    I recompile the project in framework 3.5 and integrate the dll in unity. I try to use the TestForm code class in a unity script and so I can see and read input from Wacom, but my problem is that when I try to close the application I cant and I need to force it to close.

    I found that the problem could be in the context.Open() function but I can't figure out how to solve it. could someone please help me.

    Thanks a lot Miky.

    Here after the class code:

    using System;
    using System.Collections.Generic;
    using System.Collections;
    using System.Linq;
    using System.Text;
    using System.Windows.Forms;
    using UnityEngine;

    public UInt32 m_pressure = 0;
    private UInt32 m_pkTime = 0;
    private UInt32 m_pkTimeLast = 0;

    // These constants can be used to force Wintab X/Y data to map into a
    // a 10000 x 10000 grid, as an example of mapping tablet data to values
    // that make sense for your application.

    Hi Miky!

    I'm facing something very similar, it crashes (hangs) when we try to close the context. Did you manage to solve this?

    So this seems to be caused by the WinTabDN code using threads. The only thing i've managed to do to solve this in a standalone build is to explicitly exit mono threads using the following code in OnApplicationQuit


    #if UNITY_STANDALONE_WIN
    [DllImport("mono", SetLastError=true)]
    static extern void mono_thread_exit();
    #endif

    void OnApplicationQuit()
    {
    #if UNITY_STANDALONE_WIN && !UNITY_EDITOR
    mono_thread_exit();
    #endif
    }

    I tried to do integrate the WintabDN demo in Unity, too. I got quite a similar problem. In the editor I can run the example and stop it. But when I click the play button again, the editor hangs and I have to force quit it.

    Did anyone have success integrating a Wacom tablet as input?

    I'm using Unity 5.3.2f1 personal, Win 8.1 and a Wacom CTL-490DW Intuos Draw

    Is anyone having this error, too?
