Convert a hexadecimal string to decimal

Summary

ArcView can convert decimal numbers to a hexadecimal string with the .AsHexString request, but ArcView has no request to convert from hexadecimal string to a decimal number. This document provides a sample script to do this conversion.

Procedure

1. Open a new script window.
   
   
   A. Activate the Project window.
   B. Click the Scripts icon.
   C. Click New.
   
   
2. Copy and paste the code into the new script window.
   
   

   Code:
   'Prompt user for the input hexadecimal string 
   n = MsgBox.Input("","","") 
   
   decimal = 0 
   
   'Loop through the hexadecimal string 
   for each i in 0 .. (n.count-1) 
   dchr = n.middle(i,1).UCase.AsAscii 
   if (dchr < 65) then 
   dchr = dchr - 48 ' offset for numbers 
   else 
   dchr = dchr - 55 ' offset for letters 
   end 
   decimal = decimal * 16 + dchr 
   end 
   
   'Post the results 
   msgbox.info("result ="++decimal.asstring,"")
