RS2012 R1.2 -> 2012R2.1 Invalidate(False) What changed?

Hello all,

I had to revisit an app I wrote in RS 2012R1.2. I am now using Rs2012R2.1. It worked perfectly in R1.2, but in R2.1, the canvas is not refreshed. I found that the code ‘Invalidate(False)’ is where the difference/error occurs. Can anyone tell me what is different and more importantly, how to fix this for 2012 R2.1?

Thank you,

what platform?
have you tried leaving the “false” out?

Hi Dave, thanks for your reply!

IDE Platform Win7, Target platform, Windows - happens when in debug mode or compiled. I did try leaving “False” out, and also ‘True’. No difference.
