AI Thread Summary
To implement an update check in a dialog-based MFC application using Visual Studio C++ 2005, one effective method is to establish an anonymous FTP connection to a designated website. By downloading a simple text file, such as 'latest.txt', the application can read the version number contained within to determine if an update is available. The MFC classes CInternetSession and CFtpConnection are recommended for facilitating this FTP connection, making the process straightforward to integrate into the application.

I have a dialog-based application in MFC, and I was wondering what class or component do I need to implement in the app to check for new updates?

Ftp is faily easy to implement from MFC see CInternetSession and CFtpConnection
