viEnableEvent using VI_EVENT_CLEAR

Hello,

I am using the C/C++ visa API.

I am using the following function:

viEnableEvent(ViSession, VI_EVENT_CLEAR, VI_QUEUE, VI_NULL), and this returns VI_ERROR_INV_EVENT(Specified event type is not supported by the resource.).

Does this mean that I can't use the function viClear ?

Because I am getting error VI_ERROR_SYSTEM_ERROR when I am using viClear, even if I use the NI-MAX GUI.

NB: I am new to this forum, is this the good place to ask this kind of question ?
