CAtlWinModule::AddCreateWndData
This method initializes and adds an _AtlCreateWndData structure.
void AddCreateWndData(_AtlCreateWndData* pData, void* pObject);
Parameters
pData
Pointer to the _AtlCreateWndData structure to be initialized and added to the current module.
pObject
Pointer to an object's this pointer.
Remarks
This method calls AtlWinModuleAddCreateWndData which initializes an _AtlCreateWndData structure. This structure will store the this pointer, used to obtain the class instance in window procedures.
CAtlWinModule::CAtlWinModule
The constructor.
CAtlWinModule();
Remarks
If initialization fails, an EXCEPTION_NONCONTINUABLE exception is raised.
CAtlWinModule::~CAtlWinModule
The destructor.
~CAtlWinModule();
Remarks
Frees all allocated resources.
CAtlWinModule::ExtractCreateWndData
This method returns a pointer to an _AtlCreateWndData structure.
void* ExtractCreateWndData();
Return Value
Returns a pointer to the _AtlCreateWndData structure previously added with CAtlWinModule::AddCreateWndData, or NULL if no object is available.
