Preprocessor Errors

unknown argument ignored The MIDL compiler does not recognize the command-line argument as a switch, a switch argument, or a file name. The compiler discards the unknown argument and attempts to continue processing. If everything appears correct but this error persists, check to see if the arguments to the command-line switch are passed to the MIDL compiler in a response file. If they are and if the arguments are a file name that uses the multibyte character set (MBCS), ensure that the file name contains no spaces. If it does, delete the spaces, invoke the MIDL compiler and its arguments from a batch file, or enclose the file name in quotes.
