I have a program that shows the content of a large text file in which I 
want to look for certain patterns visually. I use ScreenPutString() to 
print so when I run it at full screen I get very much pages per second 
and I can watch all the file in less than a minute, but in a graphic 
window under windows XP you get very low refresh rate and this is not 
practicall.

This is a concern to all interactive console applications, on which that 
awfull delay between program printing and window updating, gives a false 
sense of slowness.

Does anybody know a trick to speed up text printing in a graphic Windows 
NT/XP console?

Thanks
