Hi Tom

First of all please accept my apologies for not acknowledging your response to my last question.  I have only just seen it on your message board.  It never came through to my email.  The VBA worked perfectly.

The following is a piece of code that is in a workbook that I am using.  

' Letter color constants
   Const lLETTER_FILL_ON   As Long = 255       'rgb(255,0,0)
   Const lLETTER_FILL_OFF  As Long = 16777215  'rgb(255,255,255)
   Const lLETTER_FONT_ON   As Long = 0         'rgb(0,0,0)
   Const lLETTER_FONT_OFF  As Long = 16777215  'rgb(255,255,255)

There is an eight digit number and a nine digit rgb reference.  I would like to convert a nine digit rgb reference (191,191,191) to an eight digit number.  Could explain how this is done?

Thanks in advance.



If you are working in the Visual Basic Editor, you can make the immediate window visible and then in the immediate window to

?  rgb(191,191,191)

the results will show as


If you wanted to use a function in the worksheet you could paste this in a general module.

Public Function ConvertRGB(red As Long, green As Long, blue As Long)
 ConvertRGB = RGB(red, green, blue)
End Function

then in a worksheet do

=ConvertRGB(191, 191, 191)
