TextBox1.Text = d.ToString("0.000e0")

Answer 2

Converting a Double to a string:

Formatting numbers:

You probably want to look at the exponent (e) format.

Answer 3

from the documentation

Dim value As Double = 12345.6789

Debug.WriteLine(value.ToString("E"))

' Displays 1.234568E+004

Debug.WriteLine(value.ToString("E10"))

' Displays 1.2345678900E+004

Debug.WriteLine(value.ToString("e4"))

' Displays 1.2346e+004
