I want to make a stylus, its mechanism will make color adjustments from Form1 and it will open Transparent Form2 and click on it to act as a pen.
Make sure Form2's transparency is "this.Opacity = 0.01;" make sure it is. make sure it is. make sure it is. I tried with a pen, but the traces left by the pen were also transparent and it didn't work.
this.BackColor = Color.Transparent; this.TransparencyKey = Color.Transparent; system.ArgumentException: 'Control does not support transparent background colors.' i got the error
