Description
Returns the instance handle for the module in which a class type is defined.
FindClassHInstance finds the HInstance of the executable or library that owns, or contains, the run-time type information (RTTI) and the Virtual Method Table (VMT) for the specified class passed in as the Class Type parameter. When reading a component (which is a type), this information is needed in order to be able to load the form file (resources) associated with that component. The component streaming system uses FindClassHInstance for this purpose.
FindClassHInstance returns 0 if the instance is not found. Otherwise it returns the class owner's HInstance.
