ICommonLayoutDefinition

IID_ICommonLayoutDefinition {D72FF553-AE8F-4DAE-9EE8-833A9E025CB0}

The ICommonLayoutDefinition interface has just the one method (after the IUnknown methods):

Offset Method
0x0C ChooseLayout

with prototype:

HRESULT ChooseLayout (LAYOUTTYPE);

in which LAYOUTTYPE is invented as a typedef for an undocumented enumeration:

typedef enum tagLAYOUTTYPE LAYOUTTYPE;

Availability

The ICommonLayoutDefinition interface is implemented in SHELL32.DLL in the version 6.00 from Windows Vista, and higher.

Though new for Windows Vista, this interface is not documented by Microsoft in the January 2007 edition of the Software Development Kit (SDK) for Windows Vista.
