      • Hi All, I'm trying to grasp the purpose of simple Properties in C++/CLI. Say you have a v1 class, which has a simple property, Data, which is automatically serialized as <backing_store>Data. Then say that in v2, you now have a need to put in validation for this property, so you implement Data::get and Data::set to operate on a private m_Data field. When you now deserialize a v1 object

      • Hello, I'm hoping for a reality check here. The following program generates a floating point exception in the vector::resize call. I compiled it under VC 2005 using the command line in the comment below. I've disassembled the executable and found that vector::resize creates a default Point object which is then copied to the new empty elements at the end of the vector.
