You probably would need a binary or text format in which you will be able to save, and from where you can load the object. The simplest way is using kind of serialization. Try using MFC serialization, or implement your own one. Think about implementing a protocol, or using an existing one, compatible with existing protocols.

If the objects contain dynamic content like allocated memory or pointers to allocated memory they can't be send. More precise: They can be send but the dynamic members are invalid on the receiving side.

You may split the content into parts that can be re-assembled on the receiving side. This is simple for plain memory blocks by sending an identifier, the size, and the content. But it's getting more complicated for blocks containing dynamic content itself.

You can !
But I think, you should not. Because it depends on what kind of data that object holds. The member variables of the class my be holding reference to other object, address to some memory location on your local machine heap, or handle to the file.
e.g. If the object you are transmitting holds any pointer variable, there's no point in building that object by transmitting through socket like you are thinking. Rather you can transmit the relevant information over socket, this way you even can reduce the traffic over the communication channel.

BTW, what's that you wanna achieve by doing this ?
