control

Specifies that the user-defined type is a control.

[control]

Remarks

The control attribute implies the coclass attribute. The control C++ attribute has the same functionality as the control MIDL attribute.

Example

// cpp_attr_ref_control.cpp
// compile with: /LD
#include <windows.h>
[module(name="Test", control=true)];

[object, uuid("9e66a290-4365-11d2-a997-00c04fa37ddb")]
__interface ICustom {
   HRESULT Custom([in] long l, [out, retval] long *pLong);
};

[coclass, control, appobject, uuid("9e66a294-4365-11d2-a997-00c04fa37ddb")]
class CTest : public ICustom {};
