Last week I got to actually doing it, and I'm quite satisfied with the results. NET application - Win Forms or WPF, and it offers great flexibility through interfaces, for feed readers, file sources, and update tasks.
It also supports conditional updates, the implementation of which offers unlimited extendibility. NET-Auto-Update, and although I practically rewrote almost everything, he certainly deserves this credit.
This is a look at the Win Forms sample app that creates and zip files. Some of them don't have enough features (Eg, AES encryption, ZIP64, zip spanning). What I found is that most people want something simple and easy to use, that works well, has good features, compresses effectively and fast, and is the right price. NB: If you open an AES-encrypted ZIP file in Windows Explorer, whether generated by Dot Net Zip or some other tool, you will be able to view the list of files, but you won't be able to extract entries. The advanced features, for things like selecting entries from the zip file, or AES-encryption, or self-extracting archives, are not available using the shell library. To view the chm file, within Windows Explorer, right-click on the CHM file, select properties, and Unblock it (button in lower part of properties window). As well you can Read a zip archive from an open stream - I use this for embedded resources in apps: I call Get Manifest Resource Stream(), and then unzip that resource. Unlike some other libraries, in most cases Dot Net Zip handles the streaming; your application does not need to implement a Read/Write data pump. Using the stream support, you could, for example, open a zip archive, and then modify the files in the archive, and Save out to a Response. Does this library allow removal of entries from zip files, or updating of entries in zip files? Do I have to write programs to take advantage of this thing?
Instance was loaded with some configurations in the Form constructor): // Get a local pointer to the Update Manager instance Update Manager upd Manager = Update Manager. Check For Updates(source)) else Update Manager upd Manager = Update Manager.
Instance; // Only check for updates if we haven't done so already if (upd Manager.
Update 30/03/2011: A user/developer discussion group is now available at: Here are some code snippets, taken from the Win Forms sample application.
First is the method checking for updates (Update Manager. Not Checked) // Check for updates - returns true if relevant updates are found (after processing all the tasks and // conditions) if (upd Manager.
