quesion about link

[gucy]

my regular dll is dynamicly linked to my application.the regular dll is built using the dynamic_link library version of mfc while the application is built using the static_link library version of mfc. when i call AfxGetInstanceHandle() in my regular dll.it caused severe error. then i rebuild my application using dynamic_link library version of mfc.it is ok. i wonder if i must use dynamic_link library of mfc in my application when the application calls a regular dll. gucy

not necessarily. It could be std itself. Check /MD, /MT compiler flags.
