The INVOKEKIND enumeration is used to specify the way in which a function is to be invoked by IDispatch::Invoke.

Syntax
typedef enum tagINVOKEKIND {
INVOKE_FUNC = DISPATCH_METHOD,
INVOKE_PROPERTYGET = DISPATCH_PROPERTYGET,
INVOKE_PROPERTYPUT = DISPATCH_PROPERTYPUT,
INVOKE_PROPERTYPUTREF = DISPATCH_PROPERTYPUTREF
} INVOKEKIND;
Elements
INVOKE_FUNC
The member is called using a normal function invocation syntax.
INVOKE_PROPERTYGET
The function is invoked using a normal property-access syntax.
INVOKE_PROPERTYPUT
The function is invoked using a property value assignment syntax. Syntactically, a typical programming language might represent changing a property in the same way as assignment. For example: object.property : = value
INVOKE_PROPERTYPUTREF
The function is invoked using a property reference assignment syntax.
Remarks
In C, value assignment is written as *pobj1 = *pobj2, while reference assignment is written as pobj1 = pobj2. Other languages have other syntactic conventions. A property or data member can support only a value assignment, a reference assignment, or both. For a detailed description of property functions, see Chapter 5, "Dispatch Interface and API Functions." The INVOKEKIND enumeration constants are the same constants that are passed to IDispatch::Invoke to specify the way in which a function is invoked.
