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.
