Loosely translated.
Well, I was using a very weak computer for a short time and for that matter did not use Windows 10 (which particularly like very much!), and recently I upgraded, and installed the latest build of Windows 10 (version 1903, build 18342.8).
Anyway leaving the story aside, I went to test my application on my new computer (with WIN10) that I used in my old computer (with Win7).
And when I use the. ShowModal or. ShowDialog it gives error!
