Serializing an Array. Possible?

[nyjil]

How do I serialize an array? I know it is possible to serialize int, CStrings, and other such variable forms. However, what if I have an hypothetical object, lets call it a CCat object. This object is made from 3 integer variables, and a CString variable. How do I serialize the whole object? Now the real question comes, how do I serialize an array of CCat objects?

What I'm looking to do is to save to disk and then later draw from that disk some information. Serialized data, so to speak. Not too hard. I have done it many times with common variables, but never a whole object. What makes it tough for me is the array. Further complicating matters is that my array is a two-dimensional array (i.e.
CCat[25][10]). In otherwords, I have 25 CCats across and 10 rows of CCats.

Any help on this matter would be greatly appriciated. Happy Holidays.

serialization and arrays (or anything that is not an object) are like oil & water, but maybe this will help:

If you know to serialize an object, so what you need to do is:

1st, serialize the number of objects you have, then serialize object after object in a for (){} routine.

for reading, do the same, read the number of objects, then make a for from 0 to the number of objects you read -1, and read object by object.

Thank you both for your advise. A simple 'for' statement should do the trick. Next question. How do you serialize an object?

Hi

You add the function Serialize to your object class

void CMsg::Serialize(CArchive& ar)
{

if (ar.IsStoring())
{
ar << m_lAppId;
}
else
{
long l;

ar >> l;
m_lAppId = ( int) l;
}
