I do not understand who shall handle the WM_TIMER messages? Currently TIcsWndControl skips message numbers below WM_USER, do you want to change that? WParam of WM_TIMER can hold a custom 32 bits value like an object reference. Another idea is to have something like a heartbeat dispatcher. A singleton class that utilizes a single windows timer, it the broadcasts a custom window message to all subscribers. Usually you don't need high resolution timers in network applications, a lazy heartbeat with let's say a 1 sec resolution was precise enough to handle timeouts and other common stuff.
