/MIDL (Specify MIDL Command Line Options)
Visual Studio 2008
/MIDL:@file
All options for the conversion of an IDL file to a TLB file must be given in file; MIDL command-line options cannot be specified on the linker's command line. If /MIDL is not specified, the MIDL compiler will be invoked with only the IDL file name and no other options.
The file should contain one MIDL command-line option per line.
