Assume you has Two Dialog A and B now you want to Pass data From A to B . a Simple way is create a object of B in your A now easily you can access all the member variable of B in A . Simply use your member variable of B in A Asign them value now inside B you can See that all those value is visible to you.Now Second question where to put TCP/IP code in your program it's Depend on you better you made a seperate File for all communication related work and according to your requirement in your project access the Function mention in your communication files.
Thanx

Not objects but pointer to other dialog class object, you will need to assign it other dialog's value before using it.
About the TCP/IP problem, can you post the code you have here ?hello . wat's that. even you can assign it after Invoking the Dialog it's depend on your rquirement. you also can use user defined Fucntion and can invoke it from your dialog a and inside your user defined Function you can chage the 2nd Dialog member variable value with param parameters . which you are sending from 1st dialog by SendMessage() or PostMessage() . and there is no need to taking pointer to a object.everyone should familiar where to use pointer to a Object or simply a Object .Even in your above senario there is no need to use pointer to a Object.and if you want all the variable inside your OnInitDialog Function then only you have to assign them before using the dialog other wise you can assign them according to your requirement with the help of user Defined Message.
Thanx
It can be done by SendMessage or PostMessage functions.
The other way is using 'extern' variable.

Hi,
Just note that you socket has to be created in the main GUI thread (if it's an async communications)
I encountred this problem when trying to use CAsyncSocket for async communications.
Cheers,
I think you want to share data between the classes; if so why can't you go for a friend function or else why can't you create an object of that class in the other and use that variables.
Your question is giving wrong sence "How to use tcp/ip in multiple dailog box program". Once revise your application design.
Cheers,
