INVOKEKIND enumeration (oaidl.h)

  • 02/22/2024

Specifies the way a function is invoked.

Syntax

typedef enum tagINVOKEKIND {
  INVOKE_FUNC = 1,
  INVOKE_PROPERTYGET = 2,
  INVOKE_PROPERTYPUT = 4,
  INVOKE_PROPERTYPUTREF = 8
} INVOKEKIND;

Constants

 
INVOKE_FUNC
Value: 1
The member is called using a normal function invocation syntax.
INVOKE_PROPERTYGET
Value: 2
The function is invoked using a normal property-access syntax.
INVOKE_PROPERTYPUT
Value: 4
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
Value: 8
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. The INVOKEKIND enumeration constants are the same constants that are passed to IDispatch::Invoke to specify the way in which a function is invoked.
