View 11 RepliesRead CSV File Into Array Sort / Add / Edit / Delete And Write Back To CSV
Aug 15, 2011The gist of the program is to:
- Read a CSV file into an array
- Get this visible in a list box, so the values can be:
- Sorted
- Edited
- Deleted
- Added
- Finally save these manipulated values back to the text file
Would love some suggestions and code as to how to get this going, hopefully I'll get the hang of it and come back and fourth for help
Site Level Folder Read/write/delete Permissions From Webpage?
Dec 20, 2011I have a link on a VB.net aspx page that needs to open a folder in a subdirectory of a web site and provide read and write permissions so that files can be copied into and read from as well as deleted. ONLY from this folder.I have this funtionality working on a dev and demo PC but they are both on my domain. Clicking the link opens Windows Explorer and I can copy /cut & Paste, etc.The public/production PC is on the LAN, but not part of the domain. I know there are ways to allow folder read/write permissions on a public server like this but I am not too sure on the safest way to do this. The upside, the only users that need to have read/write/delete access are employees. Forms Authentication, ASP Membership directs non-employees to other pages within the site. Likewise, the membership directs employees to an admin section of the site.
