Parameters
- cSelect
Type: System.UInt32
[in] Specifies the number of selected items—the number of elements in the array of objects returned by GetObjects and saved in apUnkSelect.
- apUnkSelect
Type: array<System.Object[]
[in][out] Pointer to the array of objects returned through GetObjects.
- dwFlags
Type: System.UInt32
[in] Flags that modify the selection. If set to SELOBJS_ACTIVATEWINDOW, the caller is requesting that the window showing the selected objects should be activated.
Return Value
Type: System.Int32
If the method succeeds, it returns S_OK. If it fails, it returns an error code.
Remarks
COM Signature
From designer.idl:
HRESULT ISelectionContainer::SelectObjects(
[in] ULONG cSelect,
[in, size_is(cSelect)] IUnknown ** apUnkSelect,
[in] DWORD dwFlags
);
The ISelectionContainer.SelectObjects method makes it possible for any of the selectable objects returned by GetObjects to be selected. Before returning, SelectObjects saves a local copy of its ISelectionContainer pointer by calling ISelectionContainer.AddRef and then reporting the changed selection to the environment with a call to OnSelectChange.
Because the returned objects support IDispatch, the caller can obtain information such as their name by calling either IDispatch.Invoke with a predefined dispatch identifier (DISPID) that represents the desired information. Declared DISPIDs are negative to ensure they do not conflict with user-defined identifiers.
The following table describes some of this information and where from and how it is obtained. These DISPIDs are defined in the header file Typelib2.h.
