From the VCL help:
Use Assigned to determine whether the pointer or procedure referenced by P

Assigned(P) corresponds to the test P<> nil for a pointer variable, and @P
<> nil for a procedural variable.
Assigned returns False if P is nil, True otherwise.
Maybe you're bumping into a pointer problem in C++?
