CBasePropertyPage::SetObjects (Windows CE 5.0)
This method provides IUnknown pointers for the objects associated with the property page. This method implements the IPropertyPage::SetObjects method.
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.
Requirements
DirectShow applications and DirectShow filters have different include file and link library requirements.
