bindable

  • Article

Indicates that the property supports data binding.

Syntax

[bindable]

Remarks

The bindable C++ attribute has the same functionality as the bindable MIDL attribute. You can use it on properties defined with the propget, propput, or propputref attributes, or you can manually define a bindable method.

The following MFC samples show the use of bindable:

Example

The following code shows how you can use bindable on a property:

// cpp_attr_ref_bindable.cpp
// compile with: /LD
#include <windows.h>
[
   uuid("479B29E3-9A2C-11D0-B696-00A0C903487A"), dispinterface, helpstring("property demo Interface")
]
__interface IPropDemo : IDispatch {

   [propget, id(1), bindable, displaybind, defaultbind, requestedit] HRESULT P1([out, retval] long *nSize);
   [propput, id(1), bindable, displaybind, defaultbind, requestedit] HRESULT P1([in] long nSize);
   [id(3), bindable, propget] HRESULT Object([out, retval] IDispatch **ppObj);
   [id(3), bindable, propputref] HRESULT Object([in] IDispatch* pObj);
   [id(-552), helpstring("method AboutBox")] HRESULT AboutBox();
};

[ module(name="PropDemoLib", uuid="479B29E2-9A2C-11D0-B696-00A0C903487A", version="1.0", helpstring="property demo") ];
