The Hex value is actually a string. You need to convert the decimal string from the textbox into a number and convert it back to a string with the option to display it as a Hex value. Here is the code:

Code:

		Dim num As Integer
		Integer.TryParse(TextBox1.Text, num)
		TextBox2.Text = Convert.ToString(num, 16).ToUpper

Note: You can convert to binary or octal just as easily by replacing the 16 with a 2 or an 8.

Code:

Dim Number As Integer
HexTextBox.Text = If(Integer.TryParse(NumberTextBox.Text.Trim, Number) = True, Number.ToString("x"), "Cannot be converted to Hex")

Standard Numeric Format Strings
