FTP Download - Needs Help
I found this VBA script online and i use to download the files from FTP Server, .img & .xml files from an ftp server. It works fine, successfully.
However, there are some issues I would need your help in resolving them.
1. The files are updated at night between 8:00 to 12:00 p.m., and delivers a end of session flag file, I want this downloading script to commence the downloading of files only after the end of session file is found in the FTP Server directory, till that time the script to hold on.
The close of session file description : 3_29112013.eos [3_ always be constant /current date[ddmmyyyy]/.eos ]
2. I want to download the lastest files which have current date in file name. File names : PRD_xxx_current date[ddmmyyyy]_01.img
3. After successful downloading of files at local disk folder create a report file in text format and email to admin as attachment.
Here is the code I have been using manually downloading of files which does not support wildcards format.
Can you please, please help?
