SharpDX_XInput NullReferenceException

[hannsen]

Hello,

when I try to start a profile where I map my X360 or X1 controller to dualshock it fails with this log message (program crashes). With keyboard (interception) it works.

Any Idea what I can do? Documentation says SharpDX_XInput is included and I do not need to install anything.

When I uninstall the X360 Gamepad drivers and reboot, it works for the first time. When I then stop and start the profile again it crashes

It only works for the first time after each reboot. When I then stop and start the profile, or close UCR and open it again it crashes.

Will try with another PC

Edit: Also not working on other pc

Edit: now 0.3 doesnt work too, either it launches and doesnt register gamepad key presses or it crashes. Sorry for the spam but it does seem quite random and works maybe 5% of the time.

Can you try this build and test if it still crashes? https://ci.appveyor.com/project/Snoothy/ucr/builds/28828417/artifacts

Sadly it still crashes with the same error

My cheap direct input controller works btw

[evilC]

My cheap direct input controller works btw Can you clarify, which provider are you trying to read the XInput controller with? DirectInput or XInput?

Cos saying that your DI controller works with DirectInput but your XI controller does not work with XInput does not really mean anything

[hannsen]

I was just saying that I only have problems with xinput not directinput to narrow down the problem

[Snoothy]

I have also encountered this while developing v0.9.0. I have not been able to do it consistently, however, it happens for Xbox -> DS4 with a simple button to button plugin. It seems to happen more often the first time such profile is created and activated

Some problem here when emulate Xbox to DS4. Only not crash when the profile only set LX, LY, RX and RY.

I think you fixed it with 0.9, right? So I close it
