Public Shared Sub ChangeWrapperHandleStrength (otp As Object, fIsWeak As Boolean)

Parameters

otp
Object

The object whose CCW holds a reference counted handle. The handle is strong if the reference count on the CCW is greater than zero; otherwise, it is weak.

fIsWeak
Boolean

true to change the strength of the handle on the otp parameter to weak, regardless of its reference count; false to reset the handle strength on otp to be reference counted.

Attributes

Remarks

ChangeWrapperHandleStrength is used for object pooling functionality and should never be called by user code directly.
