ISpecifyPropertyPages::GetPages (Windows Embedded CE 6.0)
1/6/2010
Fills a counted array of GUID values where each GUID specifies the CLSID of each property page that can be displayed in the property sheet for this object.
Syntax
HRESULT GetPages(
CAUUID *pPages //Pointer to structure
);
Parameters
- pPages
[out] Pointer to a caller-allocated CAUUID structure that must be initialized and filled before returning. The pElems field in the CAUUID structure is allocated by the callee with CoTaskMemAlloc and freed by the caller with CoTaskMemFree.
Return Value
The following table shows the return values.
| Value | Description |
|---|---|
E_OUTOFMEMORY |
Out of memory error. |
E_POINTER |
The address in pPages is not valid. For example, it may be NULL. |
E_UNEXPECTED |
Unexpected Error. |
S_OK |
The array was filled successfully. |
Remarks
The CAUUID structure is caller-allocated, but is not initialized by the caller. The ISpecifyPropertyPages::GetPages method fills the cElements field in the CAUUID structure. This method also allocates memory for the array pointed to by the pElems field in CAUUID using CoTaskMemAlloc. Then, it fills the newly allocated array. After this method returns successfully, the structure contains a counted array of UUIDs, each UUID specifying a property page CLSID.
Notes to Callers
The caller must release the memory pointed to by the pElems field of CAUUID, using CoTaskMemFree when it is no longer needed.
Notes to Implementers
E_NOTIMPL is not allowed as a return value since an object with no property pages should not expose the ISpecifyPropertyPages interface at all.
