activex

Please tell us how to create an ActiveX control in C#. Internet searches only return VB and C++. I am specifically interested in the type of project in C#. And if anyone has links to books on the subject, please throw it off.

I had COM, used in chm (html help), worked fine in Windows XP, but then... The question is: has Microsoft abandoned them now? ... hrough the shell. If it is very interesting, you can see on .chm. To call up the code, you can click on the icon with the CD.

I can't change the size of the Excel activex checkbox, is there any way to change the size as it is very small and the font size option is disabled, I really wanted to leave it the desired size?
