Problem in ole32.CoCreateInstance ?

Sorry, I didnt notice that lpclf is the variables that receives the
pointer.

Yes, found it. The problem isnt in the macro. :)
We should add a check in the case no class factory is found, to avoid
crashing.
But I dont understand why CoGetClassObject returns ok and leaves lpclf
set to NULL.
Adding a TRACE after CoGetClassObject I get :
trace:ole:CoCreateInstance sanity check: hres=80040154, lpclf=00000000
trace:ole:CoCreateInstance sanity check: hres=00000000, lpclf=41fb14e4
trace:ole:CoCreateInstance sanity check: hres=80040154, lpclf=00000000
trace:ole:CoCreateInstance sanity check: hres=00000000, lpclf=40289148
trace:ole:CoCreateInstance sanity check: hres=00000000, lpclf=4029b7f8
trace:ole:CoCreateInstance sanity check: hres=00000000, lpclf=4029b830
trace:ole:CoCreateInstance sanity check: hres=00000000, lpclf=4029b668
trace:ole:CoCreateInstance sanity check: hres=00000000, lpclf=00000000
<= shouldnt happen.
