Exe under Windows uses resources in Dll

Problem: ResourceHandle defaults to InstanceHandle, so using resources in Dll will fail.

//Switch from exe to dll, then switch from dll to exe
HINSTANCE hExe = AfxGetResourceHandle();
HINSTANCE hDll = AfxGetInstanceHandle();
hDll = ::GetModuleHandleA("KqGisFrame.dll");
AfxSetResourceHandle(hDll);
CHelloDlg dlg;//The resource of the dialog is located in the dynamic library;
dlg.DoModal();//But the default is to run the instance when loading resources;
AfxSetResourceHandle(hExe);//So switch
