CWinApp::m_hInstance

对应于Windows传递的 hInstance 参数传递给 WinMain。

HINSTANCE m_hInstance;

备注

是处理对应用程序的当前实例运行在Windows下的 m_hInstance 数据成员。 这是通过全局函数 AfxGetInstanceHandle返回。 m_hInstance 是类型 HINSTANCE的公共变量。

示例

// 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);
