VBScript / Excel / SendKeys / Sleep - Solution

This is a script I wrote to help me add IPTC information to over 1200 images. It contains several techniques you might be able to use in your own VBScripts.



' Based on a script to automate Excel with VBscript by Richard L. Mueller
' Demonstrates several additional functions including
' 1) Launching applications
' 2) using SendKeys to control application
' 3) useing Sleep to pause execution during the script
' 4) Arrays

' I wrote this script to help me update the IPTC data of images
' I had downloaded the data from MySQL and put it in an Excel spreadsheet
' Each line of the spreadsheet contains the file name and the desired IPTC information
' I leverage IrfanView to insert the IPTC information into each photograph
' This IPTC information is later read by the server using PHP when I upload the pictures to my photography web site
