NOTES ON THE BATCH FILE AND THE MIDL COMPILER. The MIDL compiler response file adds a prefix to the name of the .H file to avoid a file name clash if the Visual C++ 5.0 Class Wizard is used to generate a wrapper class for dispinterfaces from a type library. The Class Wizard will create .h and .cpp files creating a subclass of COleDispatchDriver. You may change the files names in the Class Wizard. You should rename the class in the VC++ Class Wizard since it will clash with the definition generated by the MIDL compiler. (eof)
