Thanks Wilfried/Francois At the moment this is just for a simple test app that talks to a third-party server. My comms class allows the GUI (or any class for that matter) to register an event to be called when a certain data packet is received via the socket. It just so happens in this case that I am popping up a messagebox. It seems to me that I either need to postmessage to an intermediate layer which can then call the registered events letting them know that something of interest has happened, or, pop them into a queue and have something else process them outside of the OnDataAvailable event.
By custom message handler, do you mean use a message map and define a new message type something like WM_USER+100? Does this happen only if messages are pumped whilst in the OnDataAvailable event? Would another thread calling processmessages give the same problems? Thanks. On 26/09/2007, Wilfried Mestdagh <[EMAIL PROTECTED]> wrote: > Hello David, > > Yes, a modal form is pumping messages.
