Creating self updating applications with the net compact framework
Write Line("Extracting file to ", Zip To Unpack, Target Dir) Using zip1 As Zip File = Zip File. Extract Progress, Address Of My Extract Progress Dim e As Zip Entry ' here, we extract every entry, but we could extract ' based on entry name, size, date, etc. The release includes the library, as well as some sample applications (with source) showing how to use the library. Some people are willing to give up commercial support for a lower price. Some of those other packages are complex to use for zip files. If I create a zipfile with a java/PHP/Python/C/Perl application, or with Win Rar/Win Zip/7zip, can I open it from within a . Also, Dot Net Zip's AES will work with any other tool that is compatible with Win Zip. Why would a developer not just use the ZIP capability that is built into the Windows Shell? The programming model for managed code apps is much nicer with Dot Net Zip, and Dot Net Zip is faster. Can Win RAR read the zip files produced by Dot Net Zip? But remember, Dot Net Zip does not produce RAR files. The error is: "This program cannot display the webpage." or, "The address is invalid." Is there an error with the chm file? You have likely encountered a problem with Windows protection of files downloaded from less trusted locations. Yes, you can zip up files and Save the zip archive to a stream. All the zip file content can be manipulated in memory (using Memory Stream for example).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?IT departments and web developers use wy Build and the standalone updater (wy Update) to keep their departments and clients up-to-date.No complicated scripts — just a simple updater that handles all the details.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.
Asking non-computer savvy users to do this would mean spending lots of time on helpdesk lines walking users through this potentially problematic process—and with few guarantees users would do exactly as they were told.wy Update can work in either standalone mode or fully integrated automatic update mode.Standalone-update mode is made for people who aren't using .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.
NET technologies, but want to add the best updater in the industry to their application. NET developers — whether you're working with C#, VB. — can add fully automatic updating to your application.
