方法一：
AFX_MANAGE_STATE(AfxGetAppModuleState());// MFC扩展dll
或
AFX_MANAGE_STATE( AfxGetStaticModuleState());//常规Regular dll
方法二：

HINSTANCE hEXE=AfxGetResourceHandle();
AfxSetResourceHandle((HINSTANCE)hDLL); //设定资源模块句柄，指定为DLL模块。
...// 资源的加载
AfxSetResourceHandle(hEXE); // 切换到EXE资源

有些资源加载函数需要指定资源句柄，请注意使用<span style="color: rgb(68, 68, 68); font-size: 16px;">AfxGetInstanceHandle()、</span>AfxGetResourceHandle()的使用
如：
LoadCursor（）、LoadImage（）等等。

<span style="color: rgb(68, 68, 68); font-size: 16px;">GetModuleHandle()、<span style="orphans: 2; widows: 2;">AfxGetInstanceHandle()和CWinApp->m_hInstance的区别：</span></span>

If called from within a DLL linked with the USRDLL version of MFC, an HINSTANCE to the DLL is returned. 返回的是一个application的句柄，但是如果这个函数是从一个MFC的USRDLL版本DLL的内部被调用，那么返回的就是这个DLL的句柄</div><div style="widows: 2; font-size: 16px; orphans: 2; color: rgb(68, 68, 68);"> </div><div style="widows: 2; font-size: 16px; orphans: 2; color: rgb(68, 68, 68);">3.CWinApp->m_hInstance The m_hInstance data member is a handle to the current instance of the application running under Windows. This is returned by the global function AfxGetInstanceHandle. m_hInstance is a public variable of type HINSTANCE. 因为它是从 AfxGetInstanceHandle（）返回来获得的，所以跟AfxGetInstanceHandle（）的返回值一样。</div>
