  • Artigo

3/26/2014

This method provides IUnknown pointers for the objects associated with the property page. This method implements the IPropertyPage::SetObjects method.

Syntax

HRESULT SetObjects(
  ULONG      cObjects,
  LPUNKNOWN* ppUnk
);

Parameters

  • cObjects
    Specifies the number of IUnknown pointers in the array specified by ppUnk.
  • ppUnk
    Specifies an array of IUnknown pointers.

Return Value

Returns an HRESULT value. Possible values include the following.

Value

Description

S_OK

Success.

E_POINTER NULL

Pointer argument.

E_UNEXPECTED

Unexpected failure.

Remarks

Although ppUnk specifies an array of IUnknown pointers, the CBasePropertyPage class is designed only to support one associated object. If cObjects is greater than 1, the method returns E_UNEXPECTED.

If cObjects equals 1, this method calls the CBasePropertyPage::OnConnect method. If cObjects equals 0, this method calls the CBasePropertyPage::OnDisconnect method. The derived class should override both of those methods; for details, see the remarks for those methods.
