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

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

then setting value of the `title’ member is as following:

srver = WIN32OLE.new('ComServer.ComClass')
obj = WIN32OLE_RECORD.new('Book', server)
obj.ole_instance_variable_set(:title, "The Ruby Book")

static VALUE
folerecord_ole_instance_variable_set(VALUE self, VALUE name, VALUE val)
{
    VALUE sname;
    if(!RB_TYPE_P(name, T_STRING) && !RB_TYPE_P(name, T_SYMBOL)) {
        rb_raise(rb_eTypeError, "wrong argument type (expected String or Symbol)");
    }
    sname = name;
    if (RB_TYPE_P(name, T_SYMBOL)) {
        sname = rb_sym2str(name);
    }
    return olerecord_ivar_set(self, sname, val);
}
