what is the use of AFX_MANAGE_STATE ?

Answer Posted / yassar arafath.o.s

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.

If all your resources lies in the single DLL you can even
change the default handle to the DLL handle with the help
of AfxSetResourceHandle function
