<![CDATA[James's Programming Page — HidSharp RegisterClass failed]]> 2026-06-26T20:58:41Z PunBB https://swforum.seekye.com/topic/10118/ <![CDATA[Re: HidSharp RegisterClass failed]]> Are you actually needing to load two different versions of HIDSharp at the same time?

If not, the newest version has the method HidSharp.Utility.HidSharpLibrary.ManualShutdown() for cases where you need to manually shut down before program exit / AppDomain exit.

God bless.

Error still happens in newest 2.6.4 Version

We had this Problem inside Unity Editor, when you re-enter PlayMode. Our System always opens hidsharp on Boot of the application and therefore this error happend every second time we try to test the game.

Error Message was:
InvalidOperationException: HidSharp RegisterClass failed.

A quick change to WinHidManager allows this:

     protected override void Run(Action readyCallback)
        {
            string className = "HidSharpDeviceMonitor" + Guid.NewGuid().ToString("N");

            NativeMethods.WindowProc windowProc = DeviceMonitorWindowProc;
            var wc = new NativeMethods.WNDCLASS() { ClassName = className, WindowProc = windowProc };
            RunAssert(0 != NativeMethods.RegisterClass(ref wc), "HidSharp RegisterClass failed.");

We're now working on ensuring we don't load two versions which will sort the issue out.

Is there any known issues around this?
