Displaying huge data

I want to fill CEdit control with huge amount of data. Instead of refreshing the window after the data is loaded (it may take a long time), I want to display one line at a time.

What is the best way to do this without having the control reload the same data again and again by calling SetWindowText() or UpdateData(FALSE) with same data + new line * number of lines?

Thanks

Doubt Edit controls are made for streaming. However, RichEdit controls are. Might want to take a look into their StreamIn functions. Or else you could design your own control to use
