What's the best way to build a house? 
There are many ways, ranging from thread messages (PostThreadMessage etc...) through shared memory, mailslots, pipes and shared variables (with appropriate mutexes/critical sections). Read up on them all and pick the one most suited to your application.

i am using a dialog based mfc win app. how can i retrive the value of the edit box in the cpp of another dialog box.

You can use GetParent() and from the pointer returned from this function access the edit box contents in another dialog.
Somethings seem HARD to do, until we know how to do them.

Still you can move on with the same procedure.
Another method is that say you have two classes CFirst and CSecond associated to the two dialogs. Then you can declare a pointer of the CFirst class in the CSecond class and then access the variable in the CSecond class.
Ex: When you are calling the second dialog
CSecond* mySecond=new CSecond();
mySecond->myFirst=this;
mySecond->DoModal(); // ShowWindow with Create if modeless dialog.
In the header file of CSecond dialog declare
CFirst *myFirst;
// DO not forget to include header files for both dialogs respectively.
Somethings seem HARD to do, until we know how to do them.

mySecond->myFirst=this;
in this line it is showing type conversion error.

I think that you are creating the pointer in Second.h for the class CSecond itself.Check this out.
// Include Second.h in the file where you are calling this code.
CSecond *mySecond=new CSecond ();
mySecond->myFirst =this;
mySecond->DoModal ();
Open the Second.h file and in the public section declare a pointer as
// Include the header file for First.h
CFirst* myFirst;
// Delete the memory occupied to prevent memory leeks.
Somethings seem HARD to do, until we know how to do them.

Hi Guys,
This is an issue from client. They have a server application & client applications connected to it from different PC's. Both applications are developed in mfc's using socket class.
Server application creates a socket connection & listens to the particular port, server & client sends msg in-between on time interval. Application has been running well for the past year & suddenly the client say that they can't have new client connections connected to the server but old connections are alive. This occurs randomly once in a week or so, once they restart the server application, everything works fine again.
There is no error log for this & couldn't replicate the same problem from work place.
Please suggest me the possible reason why this is happening?
Note:
Server has a socket accept() function which is in while loop waiting for new connection event. When connection arrives, it calls accept function When there is an INVALID_SOCKET error, it closes the socket. Can something go wrong suddenly? is this can be due to network, firewall, router, etc?
Thank you
Mohan

Where does this statement come from, more details would be appreciated... e.g. which socket call reports error, is it a client or a server problem, which part of the application reports error?
