Keyframing in 3DS MAX 2014 SDK c++ - c++

Question

I want to ask you guys to help me with creating keyframes in Max SDK C++.
What I've done:
Created a Controller Plugin
Inside the getValue function I've done my translations via code.
I also wrote the setValue function.
Which I think manages keyframes and stores the controllers position in a given time in a given keyframe. In this way I achieved to be able to set keys manually, but I really would like, to work with the Auto Key turned on in Max.
On the other hand, I can't see the freshly added keys values. So please help me, how could I add keyframes?
Many Thanks:

void maxProject3::GetValue(TimeValue t, void *ptr, Interval &valid, GetSetMethod method)
{
Point3 p3OurAbsValue(0, 0, 0);
tomb[0]=0;
//These positions stores my data they are globals
XPosition += (accX);
YPosition += (accY);
ZPosition += (accZ);
p3OurAbsValue.x = XPosition;
p3OurAbsValue.y = YPosition;
p3OurAbsValue.z = ZPosition;
valid.Set(t,t+1); //This answer is only valid at the calling time.
MatrixCtrl->GetValue(t, &p3OurAbsValue.y, valid, CTRL_RELATIVE);
if (method == CTRL_ABSOLUTE)
{
Point3* p3InVal = (Point3*)ptr;
*p3InVal = p3OurAbsValue;
}
else // CTRL_RELATIVE
{
//We do our translations on a Matrix
Matrix3* m3InVal = (Matrix3*)ptr;
//m3InVal->PreTranslate(p3OurAbsValue);
m3InVal->PreRotateX(rotX);
m3InVal->PreRotateY(rotY);
m3InVal->PreRotateZ(rotZ);
}

To turn on the Auto key mode try using AnimateOn() before your transformation. Also add AnimateOff() to turn off the auto key mode in the end.
I did it in one of my project to create material id animation using auto key mode.
/** Auto key on*/
AnimateOn();
/** Creating material id animation */
for(int mtl_id = 1; mtl_id <= num_sub_mtl; ++mtl_id, time += time_step)
{
mtl_modifier->GetParamBlock()->SetValue(MATMOD_MATID,time,mtl_id);
}
/** Auto key off*/
AnimateOff();
Also as a suggestion, use the max script listener to know whats happening when the animation is created using 3ds Max GUI. This will help you to recreate the animation using Max SDK.
