DirectInput: GetEffectInfo throws Exception

[piotrek1668]

I have configured a steering device with Vortice.DirectInput and try to get the EffectInfo for EffectGuid.Sine but I always get an DIERR_INVALIDPARAM Exception. The device without force feedback effects works well, so I think there is no problem.

First I make sure the device supports ForceFeedbackDriver, than I create an EffectInfo instance and try to get the info like this:

...

this.Joystick = this.directInput.CreateDevice(this.deviceInstance.InstanceGuid);

if (deviceInstance.ForeceFeedbackDriverGuid == Guid.Empty)
{
return;
}

EffectInfo effectInfo = new EffectInfo();
**effectInfo = this.Joystick.GetEffectInfo(EffectGuid.Sine); // <---- throws Exception ** 

...

Anyone an idea what is going wrong here?

So I have found a workaround. Here it is:

var effectGuid = EffectGuid.Sine;
var effectInfo = new EffectInfo();
var effectInfos = this.Joystick.GetEffects();
foreach (var info in effectInfos)
{
    if (info.Guid == effectGuid)
    {
        effectInfo = info;
        break;
    }
}
