About Serializing Complex Data
Hi all,
I want to serialize complex data and save it to a CFile object. I have found a number of examples showing the serialization and storing of the data to the file. Please send me some links/examples showing the serialization of a CObject derived class containing about 4/5 arrays of structures holding various members of CString, int and float datatypes. How do I serialize such a class? And how do I save and retrieve the contents to/from the CFile object I have created?
Thankyou.

This solution is only available to members.

In the serialise just write/read the individual variables, one after the other

Your answer was quite a help! But my data array is not a member of CArray or any other array having homogeneous data. So, can you go ahead and tell me, how can I serialize the data and save it to a txt(?) file or whatever? Here is the prototype of what I am trying to achieve:
class MyObject : public CObject
{
struct ONE
{
CString m1;
int m2;
float m3;
}
ONE First[20];
int Num_First; // holds the number of entries for struct ONE
struct TWO
{
members......;
}
TWO Second[10];
int Num_Second; //holds the number of entries for struct TWO
struct THREE
{
members.......;
}
THREE Third[15];
int Num_Third; // holds the number of entries for struct THREE
// Functions...
f(1);
f(2);
f(3);
Serialize(ar); // Serialize function for custom class derived from CObject taking CArchive data as it's parameter.
}
// end of class declaration.
The above details match to my requirements closely. Is there any way that this could be done?
Or do I have to declare each of those structs as classes derived from CObject and then serialize the data and then save it.
Or alternatively declare a CStringArray for each of the struct members separately and then get the values from the struct with a dot operator and then serialize/deserialize those arrays?
Please let me know in short the steps for how should I go abt it....
THANKYOU.
