I want to use a track-bar to change a form's opacity.
This is my code:
decimal trans = trackBar1.Value / 5000; this.Opacity = trans;
When I try to build it, I get this error:
Cannot implicitly convert type 'decimal' to 'double'.
I tried making
double, but then the control doesn't work. This code has worked fine for me in VB.NET in the past.

An explicit cast to double isn't necessary.
double trans = (double)trackBar1.Value / 5000.0;
Identifying the constant as
5000.0 (or as
5000d) is sufficient:
double trans = trackBar1.Value / 5000.0; double trans = trackBar1.Value / 5000d;
