CWinApp::m_hInstance
Corrisponde al parametro hInstance passato da Windows a WinMain.
HINSTANCE m_hInstance;
Note
Il membro dati m_hInstance è un handle all'istanza corrente del funzionamento delle applicazioni in Windows.Viene restituita dalla funzione globale AfxGetInstanceHandle.m_hInstance è una variabile pubblica di tipo HINSTANCE.
Esempio
// Typically you do not need to pass the application's hInstance
// to Windows APIs directly because there are equivalent MFC
// member functions that pass the hInstance for you. The following
// example is not typical:
HCURSOR hCursor;
hCursor = ::LoadCursor(AfxGetApp()->m_hInstance,
MAKEINTRESOURCE(IDC_MYCURSOR));
// A more direct way to get the application's hInstance is to
// call AfxGetInstanceHandle:
hCursor = ::LoadCursor(AfxGetInstanceHandle(),
MAKEINTRESOURCE(IDC_MYCURSOR));
// If you need the hInstance to load a resource, it is better
// to call AfxGetResourceHandle instead of AfxGetInstanceHandle:
hCursor = ::LoadCursor(AfxGetResourceHandle(),
MAKEINTRESOURCE(IDC_MYCURSOR));
// A better way to load the cursor resource is to call
// CWinApp::LoadCursor
hCursor = AfxGetApp()->LoadCursor(IDC_MYCURSOR);
