pc
[out] Number of objects returned.
Return Values
The return value obtained from HRESULT is one of the following:
Return Value | Meaning |
S_OK | Success. |
E_INVALIDARG | One or more of the arguments is invalid. |
Comments
The ActiveX designer implements this method.
If the caller specifies GETOBJS_ALL, the CountObjects method returns the total number of objects in the selection container. If the caller specifies GETOBJS_SELECTED, the method returns the total number of selected objects in the container.
Example
The following example implements CountObjects for a simple container:
STDMETHODIMP CMySelectionContainer::CountObjects
(
DWORD dwFlags,
ULONG * pc
)
{
if (GETOBJS_ALL == dwFlags) {
// |objects| + 1 for the container.
*pc = m_state.dwObjectCount + 1;
}
else {
// Either the container or one of the objects is always
// selected.
*pc = 1;
}
return S_OK;
}
