Huh? Help?

[Ryan B]

file_length = (int) src_topic_file->GetLength();
total_topics = file_length / TOPIC_SIZE;
TopicVector.SetSize(total_topics);

for (int i=0; i<total_topics; i++)
{
	src_topic_file->Seek(TOPIC_SIZE*i,0);
	dwRead = src_topic_file->Read(buffer, TOPIC_SIZE);
	topic.SetTopicData((TOPIC*)buffer);
	TopicVector.Add(topic);
}

TopicVector is CArray<CTopicItem,CTopicItem> topic is CTopicItem as well (derived from CObject) I have a Compile Error on the .Add line with Cannot Convert Parameter 1 from CTopicItem to CTopicItem am I doing something wrong? Ryan Baillargeon Software Specialist Fuel Cell Technologies Inc.

Did you make CTopicItem copy c'tor protected or private? CArray::Add uses 2nd template argument as data type of its parameter, so basically you're passing CTopicItem by value, which involves copying. Tomasz Sowinski -- http://www.shooltz.com

Thank you. (for making me revel in my own stupidity). The class didnt have the = or copy constructor. Ryan Baillargeon Software Specialist Fuel Cell Technologies Inc.

You may consider changing 2nd CArray template argument to const CTopicItem & anyway. This will change the way arguments are passed to CArray::Add and few other methods. Tomasz Sowinski -- http://www.shooltz.com

Can you please show me what my operator= function should look like? Ryan Baillargeon Software Specialist Fuel Cell Technologies Inc.

It depends on the internals of CTopicItem of course. Tomasz Sowinski -- http://www.shooltz.com
