Hi,

I am converting hex color value into color name.

While converting, I am facing the error like this "ffffff80 is not a valid value for Int32."

Below is my code

VB

Dim xCol As String = clspfjbs02.colrnameobj
                   Dim k As Color
                   k = System.Drawing.ColorTranslator.FromHtml(xCol)

When you read it from clspfjbs02.colrnameobj I assume it is returning a hex value "ffffff80"? If so, then just tack a '#' character in front of it :

VB

Dim xCol As String = "#" & clspfjbs02.colrnameobj
Dim k As Color
k = System.Drawing.ColorTranslator.FromHtml(xCol)

What you have is the hex representation of number, what the function wants is the actual number.

I so what you need to do is convert the hex string to a number first:

Dim xCol As Int32
Dim k As Color
xCol = Int32.Parse(clspfjbs02.colrnameob, HexNumber)
k = System.Drawing.ColorTranslator.FromHtml(xCol)

Solution 3

Try:

VB

k = System.Drawing.ColorTranslator.FromWin32(Integer.Parse("ffffff80", System.Globalization.NumberStyles.HexNumber))

:)
