Hello Altankhuu,

>> First, I use GetIDsOfNames() and it returns the dispid of XAxis without any problem. But when I call Invoke with that dispid there is an error “Access violation at address …”.

The sequence should be :

IGraph.GetIDsOfNames() to obtain dispid of IGraphAxes property.
IGraph.Invoke() (with above dispid) to obtain IDispatch* of IGraphAxes.
IGraphAxes.GetIDsOfNames() to get dispid of XAxis.
IGraphAxes.Invoke() (with above dispid) to obtain IDispatch* of XAxis.

You then call GetIDsOfNames() and Invoke() on the returned XAxis IDispatch pointer.

- Bio.
