Hi, I need to add items into the MSFlexGrid control in background. Means I
need to add 1 lakh records to my MSFlexGrid Control, but it is taking 10 min.
to fill the data. So, I have placed the filling functionality into the worker
thread and now I can able to work with MSFlexGrid. But when I scroll or click
on the control it is displaying major error and the application shuts down.
How can I solve this problem? I am expecting the solution which inserts the
data of MSFlexGrid in background while I am using the MSFlexGrid in front
end. Please give the solution ASAP...

The worker thread should not access the control. The worker thread
should use PostMessage to pass new data to the control's parent window.
The parent window message handler should put the data into the control.
The steps are outlined here: http://www.mvps.org/vcfaq/mfc/12.htm
