Textbox flickering with timer

Question

Possible Duplicate:
How to fix the flickering in User controls

my textbox flickers when it updates the text.
I update my textbox with a timer that ticks every 100 ms. (See it as a log window).

Question
How can I prevent this flickering?

Thanks!

@HenkHolterman Even if I lower the rate to 500 ms, it still flickers. — Yuki Kutsuya, Apr 06 '12 at 10:33
Never mind, got it! beta's solution worked, I added Application.DoEvents() EDIT: I think my video card is good enough: ATI 6870 crossfire. — Yuki Kutsuya, Apr 06 '12 at 10:37

I think you should either:

a) Slow down the tick rate of your timer

b) Enable double buffering

c) Put Application.DoEvents() right after the line which adds text to the TextBox

This is more of a workaround solution, though. I'd just lower the tickrate.

Thanks, this worked perfectly! I've picked option c :). – Yuki Kutsuya Apr 06 '12 at 10:39
