CWinApp::m_hInstance
對應於視窗的 hInstance 傳遞參數至 WinMain。
HINSTANCE m_hInstance;
備註
m_hInstance 資料成員是控制代碼在 Windows 下的應用程式目前的執行個體。 這是由全域函式 AfxGetInstanceHandle傳回。 m_hInstance 是型別 HINSTANCE的公用變數。
範例
// 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);
