缺省情况下MFC使用主应用程序的资源句柄来载入资源模板，而DLL中的资源模板是存在于DLL模板中，因此要使用这一语句切换到由AfxGetStaticModuleState返回的正确的模块状态，得到正确的句柄。

dll中资源是共享的用了这个函数的防止不同的进程修改资源产生错误!

也就是說，並不是每一个dll的输出函数前都要调用它，只有在要輸出對話框等用到資源時要調用！

摘自MSDN:
By default, MFC uses the resource handle of the main application to load the resource template. If you have an exported function in a DLL, such as one that launches a dialog box in the DLL, this template is actually stored in the DLL module. You need to switch the module state for the correct handle to be used. You can do this by adding the following code to the beginning of the function:
AFX_MANAGE_STATE(AfxGetStaticModuleState( ));
This swaps the current module state with the state returned from AfxGetStaticModuleState until the end of the current scope.
