As we answered you by e-mail, problem occurs due to different instances of class types in exe and dll
modules. In other words, object with type TMyQuery created in exe has different class type than object with type TMyQuery created in dll. To make exe and dll module use the same instances please enable using
runtime packages:
check Project -> Options -> Packages -> "Build with runtime packages"
and add dac70 and mydac70 packages to list.
