You are right. How could I miss it?
The timer that is working on my form skips events.
But solution is working.

Sometimes all you need is a simple question to answer to :)
Thanks

>>But here is a problem I am still having. Here is how I am testing solution.
>>I have a simple form with a timer that generates a short text (current time) every second.
>>On a remote computer I have an object that runs as a com server. That server actually communicates with .net exe via WM_COPYDATA. So, my form sends data to the remote server and the later sends data to .Net. Like I said everything is working.
>>But sometimes I am losing data. In .Net I am writing each event to Console. That's how it looks:
>>10:10:01
>>10:10:02
>>10:10:03
>>10:10:04
>>.....
>>10:10:19
>>10:10:21
>>10:10:22
>>
>>It goes for a 20-30 secs fine that I see missed event, that it can go fine for another half of a second, and missed data again.

>>Any idea you might have why that's happening?
