Method: WIN32OLE::Record#method_missing

Defined in:

win32ole_record.c

#method_missing(name) ⇒ Object

Returns value specified by the member name of VT_RECORD OLE variable. Or sets value specified by the member name of VT_RECORD OLE variable. If the member name is not correct, KeyError exception is raised.

If COM server in VB.NET ComServer project is the following:

Imports System.Runtime.InteropServices
Public Class ComClass
    Public Structure Book
        <MarshalAs(UnmanagedType.BStr)> _
        Public title As String
        Public cost As Integer
    End Structure
End Class

Then getting/setting value from Ruby is as the following:

obj = WIN32OLE.new('ComServer.ComClass')
book = WIN32OLE::Record.new('Book', obj)
book.title # => nil ( book.method_missing(:title) is invoked. )
book.title = "Ruby" # ( book.method_missing(:title=, "Ruby") is invoked. )

# File 'win32ole_record.c', line 450

folerecord_method_missing(int argc, VALUE *argv, VALUE self)
{
    VALUE name;
    rb_check_arity(argc, 1, 2);
    name = rb_sym2str(argv[0]);

#if SIZEOF_SIZE_T > SIZEOF_LONG
    {
        size_t n = strlen(StringValueCStr(name));
        if (n >= LONG_MAX) {
            rb_raise(rb_eRuntimeError, "too long member name");
        }
    }
#endif

    if (argc == 1) {
        return olerecord_ivar_get(self, name);
    } else if (argc == 2) {
        return olerecord_ivar_set(self, name, argv[1]);
    }
    return Qnil;
}
