Sorry for asking again. I spent today and I could not solve it.
I understand that I need to “update” the component by this.ExpireSolution(true);. But I do not know how to do this correctly, when I make the windows form in Visual Studio. I also tried to compile your code from c# component, and it worked, but due to my programming skills, I do not know how to do the same thing when designing visual studio windows form.
I have a windows form in visual studio and component that opens a windows form already. And I get the value after pressing a button.
How to do the same thing that you did with c# with track bar?
Also I uploaded .cs files, as they are not readable here.CurvatureAnalysis.Designer.txt (5.5 KB)
