Question about document/view app in MFC

Hello,
I have a real general question, but can post specific code if it helps illustrate my question. When I create a document/view app with the app wizard in VC++ 6.0, it automatically sets up the visual aspect of the File - Open, File -Save, etc options.
I am trying to write an app that will load a simple text (ASCII) document in the window. To do this, I know that I have to add code to the Serialize function. What I do is something similar to the following:

Code:

void CTestDoc::Serialize(CArchive& ar)
{
	if (ar.IsStoring())
	{
		ar << mStr ;
		// TODO: add storing code here
	}
	else
	{
		ar >> mStr;
		// TODO: add loading code here
	}
}

In the above example, mStr is a CString. When I do this and compile it and attempt to open an ASCII file, I only see the first line of the file and it seems to cut off the first letter of the line as well. I figure it has something to do with putting the value of ar into a CString rather than a better storage container, but I am not sure which storage container to use. Should I be usiing a character array or something? I think that once I know which storage container works best for my needs, it'll work just fine.

Any nudges in the right direction would be great!
Thanks as always!

Serialization is one feature in Doc/View architecture. However, you are not locked on it. You can implement C++'s ifstream if you wanted to.

Thanks for the response. If I opted to try and do this with serialization, is there a way to load a multiline ASCII document into an MFC app? Honestly, I've never really used ifstream previously, so I suspect that might be more involved...

I just wonder if there's a way to store the value of the ar (CArchive object) into something bigger than a CString (like an array or linked list or other data structure).

Thanks!
