Now my problem is if suppose 16 threads are running together a dialog box is displayed and when i click cancel or ok one by one 16 same dialog boxes are displayed. Now what i want is only one instance of that dialogbox should be displayed not those 16 instances.... how can i do this... can anybody help me in this?? thanks in adavance Re: Opening one instance of dialog box after cancel or ok it shouldn't be displayed again..... SandipG 1-Sep-08 21:20 SandipG 1-Sep-08 21:20  Simple Solution is use flag. when you show the dialog for first time set the flag to true and then every time check for this flag before showing dialog. If flag is true don't show the dialog.. I hope that makes sense. Regards, Sandip. Re: Opening one instance of dialog box after cancel or ok it shouldn't be displayed again.....

I observered that my application takes much time to transfer the data, when compared to Hyperterminal.(probably 10 times) Is it because of my coding problems or problem with windows application? Do I need to do optimization.But still i dont think i can increase the speed, by almost 10 times. Why hyperterminal is taking lesser time? Please clarify. Regards, Sunil Kumar Re: Serial port transfer speed Roger Stoltz1-Sep-08 21:29 Roger Stoltz 1-Sep-08 21:29  You are most likely using non-overlapped mode. The consequence of this is that the driver only handles one IRP at a time. This means that if you've issued a read request with a call to ::ReadFile(), the driver will be "blocked" until the read request times out and a write request can be handled. How long time it takes depends on how you've set up the comm timeouts with a call to ::SetCommTimeouts().

I read that overlapped mode will have many overheads. Which mode is efficient??

What kind of overhead and what would be the impact? Forget about that. There might be some kind of overhead in theory, but in practice this overhead is presumably in the nano-/micro-second scale. Compared to calls that block for many milliseconds or even seconds, the possible overhead that is added by the use of overlapped I/O is ridiculously small. In short: to be efficient you have to use overlapped mode.
