AFX_MANAGE_STATE(AfxGetStaticModuleState());
-
Hi I have a dll with exported functions, which I protect with
AFX_MANAGE_STATE(AfxGetStaticModuleState()). Fine. Now, to those functions I send a callback function as a param. This callback function is in the exe. Is there a corresponding way to restore the module state when I get back into the exe, or do I need to roll up my sleves for this one? It's a requirement that the writer of the dll shouldn't be bothered with restoring the state before calling the callbacks, but just setting his own state correctly using theAFX_MANAGE_STATEmacro. tia Niklas -

Are you accessing resources in the dll and the callback? Mark

Yes. :( The dlls may supply dialogs, as well as calling one of the callbacks to invoke the exes dialogs (along with other things)
I would think you'd just need AFX_MANAGE_STATE(AfxGetStaticModuleState()) at the top of the callback function. As long as the module handle is set properly so MFC can find and load resources when it needs to. This can also be overriden by loading the resources yourself if you need to. Mark

After some investigation I found that
AFX_MODULE_STATE* pPrevModuleState = AfxSetModuleState(NULL);on entry, andAfxSetModuleState(pPrevModuleState);on exit seems to work. This will allow me to load the correct resources and also use AfxGetApp() and its compadres. (though I'm not entirely convinced yet) thanks for your time. Niklas -
