In my project, I get a lot of data from CAN, and want to display them in a List table which is created in a dialogue class, as faster as better
Unfortunately, I found the updating one item of the list table takes about 2~3 ms , I exptect it less than 1 ms, even 500 us
I have tried multiple threads method for two days, BUT failed, PostThreadMessage() lost messages!
I have tried to use timer counter, the updating speed not get better;
Q1, Does MFC 's message handlers are mutiple threads? if so, I would split the data's display on several messages handlers
Q2, For Window or MFC, 1ms time response is a limit? which can't be more faster?
Q3, Is there any method to speed up updating data of a dialogue in MFC? I have chekced the some window's based program,such as VECTOR CANoe, they updates data on window's UI very quickly .
Thanks
