Detailed Description

template<class T, int resType>
class owl::TResource< T, resType >

TResource simplifies access to a resource by encapsulating the find, load, lock and free steps for accessing a resource.

• 'T' represents a structure which defines the binary layout of the resource.
• 'resType' is a constant string that defines the resource type. For example,

       typedef TResource<DLGTEMPLATE, (int)RT_DIALOG> TDlgResource;
       TDlgResource dlgInfo(hInstance, IDD_ABOUTDLG);
       DLGTEMPLATE* pDlgTmpl = dlgInfo;

template<class T , int resType>

owl::TResource< T, resType >::TResource	(	HINSTANCE	hModule,
		TResId	resId
	)

Loads & locks the specified resource..

References owl::TResource< T, resType >::MemHandle, and owl::TResource< T, resType >::MemPtr.

template<class T , int resType>

owl::TResource< T, resType >::TResource	(	HINSTANCE	hModule,
		TResId	resId,
		LANGID	lcid
	)

Loads & locks a resource of the type 'resType' from the module (hModule). Accepts a LanguageID for localized resources.

References owl::TResource< T, resType >::MemHandle, and owl::TResource< T, resType >::MemPtr.

template<class T , int resType>

owl::TResource< T, resType >::~TResource

(

)

Unlocks and frees the resource loaded earlier.

Note:

Unlocking and freeing of resources is not necessary in WIN32.

Member Function Documentation

template<class T , int resType>

bool owl::TResource< T, resType >::IsOK

(

)

const

Confirms whether resource was found.

Returns true if resource was successfully loaded or false otherwise.

template<class T , int resType>

owl::TResource< T, resType >::operator T *

(

)

Conversion operator to point to structure representing binary layout of the resource...

Returns a pointer to the locked resource.

Note:

This operator eliminates the need to explicitly cast LPVOID to a structure representing the actual layout of individual resource types.

HGLOBAL owl::TResource< T, resType >::MemHandle [protected]

Handle of resource.

template<class T, int resType>

T* owl::TResource< T, resType >::MemPtr [protected]

Pointer to locked resource.
