This update to Xceed Zip for.NET provides bug fixes and performance improvements for handling Zip archives containing a large number of items. Memory fragmentation occurring in.NET framework’s large object heap is reduced thanks to the use of alternative data structures that don’t allocate large objects. This not only benefits applications that zip and unzip archives containing more than 100000 items, but also applications that run for a long time, including ASP.NET applications. Future releases will further reduce the use of.NET’s large object heap, as well as the time it takes to process existing Zip archives containing a large number of items. Various bug fixes. Added a TarEvents class (currently undocumented).
The class should be used like the ZipEvents class. For now, TarEvents only contains the ReadingTarItemProgression event. It will be triggered during the initial reading of the Tar archive. The Tar format does not allow the component to know the total number of items without a large time penalty.
So true progression with a percentage is not possible. The event will report the value 0 in the ‘Total’ property until the last time the event is triggered. Then, the value in ‘Total’ will be the total number of items read. This will also serve to indicate that the operation has completed. Free Trial users, provide your name and email address below.

Zip or unzip to and from disks, FTP sites, memory or isolated storage. When unzipping one or more files from a Zip file located on an FTP site, Xceed Zip for.NET will download only the necessary portions of the Zip file required in order to unzip the files, for greatly improved speed and minimal bandwidth use.
Read, write, and update zip files split into multiple parts. Read, write, and update zip files that span multiple disks. Supports the Deflate64™ compression method, for improved compression. Supports the BZip2 and BWT compression methods for improved compression when speed is less crucial.
Supports the PPMd compression method, for producing the most compressed output possible, especially with text and XML files. Easy-to-use, rock-solid security through industry-standard AES encryption, compatible with WinZip 9 and higher, with encryption strengths of 128, 192, and 256 bits.
Developers can choose the AES encryption algorithm used by the component. List contents of a zip file with complete file specifications. If the Zip file is located on an FTP site, Xceed Zip for.NET will download only the central directory portion of the remote Zip file, for greatly improved speed and minimal bandwidth use. Compress or decompress any.NET stream. Compress and decompress byte arrays completely in memory. Copy, move, rename, delete files and folders in a zip file, on disk, in memory, on an FTP site, in Zip files on an FTP site, or in isolated storage. Change attributes of files and folders on disk.
Copy, move, rename, delete and change attributes of files and folders on disk, in a Zip file, on an FTP site, etc. Zip password encryption (standard Zip password encryption, or 128 to 256-bit AES encryption).
One-line shortcut classes for basic zip file and compression operations. Fully extensible classes so you can customize the library’s functionality as needed. Information-rich status report events with percentages, byte and file counts. Programmable filter system to limit processing to specific files or folders, with built-in filters for file attribute, size, date, timestamp and filenames. Create your own custom filters as needed. HTTP proxy server and both FileSystem-based and FtpClient-based SSL support.
Efficiently creates zip files by allowing developers to decide whether folder entries should be written to the archive, which reduces its size. Can create archives using the Deflate format without compression, for full compatibily with Xceed Real-Time Zip and generally improved flexibility. Need “on-the-fly” Zip file read/write capabilities for use with high-demand servers or Web sites, etc., where intermediate disk/memory storage is a major concern or simply not possible?
Multi-talented capabilities. Built-in file transfer and filesystem capabilities. Because it’s built on top of the Xceed Filesystem Core, a variety of additional file and folder manipulation capabilities are available, as is the complete functionality of Xceed FTP for.NET without any additional learning curve or effort. Abstracts the concept of files and folders in Zip files, on FTP sites, in streams, in memory, etc., so that your code is written as if it is working with regular files or folders. When support is added for more archive types and locations, there is no need to change your code in order to work with the new archive types or locations. Create self-extracting Zip files for the traditional PKZIP 2.04g compression method. Also supports the Deflate64™, BZip2, and BWT methods.
Create self-extracting zip files that support AES encryption. Use extra headers such as Unicode filenames, extended filestamps, and security descriptors. Supports the Zip64 zip file format allowing the creation of Zip files over 2 GB, which can contain a practically unlimited number of archived files. Customizable introduction message and dialog box titles. Display a license agreement with configurable accept and refuse buttons. Customize all other messages, prompts and button captions. Customize the self-extracting zip file’s application icon.

The user can enter the decryption password or skip the file if they don’t have the password for the file. Display a text file after successfully unzipping files. Customizable overwrite behavior with dialog box offering the user various overwrite options. Display unzipping status.
User interaction and dialogs can be selectively shut off for quiet operation. Execute one or more applications (optionally with parameters) or open documents after successfully unzipping files. Copy one or more files from one location to another after unzipping. Register DLLs (or other libraries) on the system after unzipping.
Add or change key values in the registry after unzipping. Create self-extracting zip files with a built-in decryption password. This prevents users from using unzipping programs to unzip the files, and therefore forces users to view your custom introduction, license agreement or warning messages. Create program groups and insert items into program groups. Associate filename extensions with applications.
Allows 3rd-party install or setup programs (and their data files) to be unzipped into a temporary folder, executed, and then deleted upon completion. Custom paths, filenames, strings and prompts are parsed, allowing you to insert strings such as the current folder, windows and windows system directories, the temporary folder, and more.

Member 12146994 17-Nov-15 6:45 17-Nov-15 6:45 Hello everyone: My question relates to the old technology. Yet it matters a lot to me to get a through answer. Could a Visual Basic expert answer me or include links to other sites and sheds light on this memory usage question please? I believe that I had not drafted my question clearly enough in my previous posting on another blog. Consider the following VB 6 code in a custom COM plus object on a page on an e-commerce site: Dom globalArray(30, 100000) ‘Assign long and short strings to the globalArray elements. Also some of the elements of globalArray hold smaller arrays.
And also load the xml: Set objGlobalDom = CreateObject('msxml2.FreeThreadedDomDocument.6.0') objGlobalDom.loadXML (xmlStr) Application.lock Set Application(“objGlobalDom”) = objGlobalDom Application(“globalArray”) = globalArray Application.unlock With any new session the following variable assignments are done: set Session(“objGlobalDom”) = Application(“objGlobalDom”) session(“globalArray”) = Application(“objGlobalDom”) Let’s suppose that the Application(“objGlobalDom”) will contain an xml with some 1000 nodes and each node takes about 3k of memory. Let’s say the array will take some 50 meg of memory. Considering VB6 and COM object: 1- I understand that each instance of the object references the object’s data. What I don’t understand is: If session(“objGlobalDom”) does not contain a copy of the application(“objGlobalDom”), why changes in the data of session(“objGlobalDom”) are not automatically reflected in the data of application(“objGlobalDom”)? Is the reference of session(“objGlobalDom”) to Apllication(“globalDom”) only for reading the data of Application(“objGlobalDom”)?
2- According to Microsoft, in a situation such as my globalArray example, the session(“globalArray”) always gets a copy of the Application(“globalArray”) and so Microsoft discourages assigning the array to session variables. But it is not clear to me that in the case of com object and object reference, does the assignment of set Session(“objGlobalDom”) = Application(“objGlobalDom”) copies the array to the session variable?
I really appreciate your answers and thank you in advance for your response. Giskard Reventlov 28-Sep-15 13:55 28-Sep-15 13:55 I spent many happy years coding with VB6 (as well as c, c, java and a few others). I am now even happier using c#. Would I go back to VB6? No, why on earth would I? What would be the point? It did a fine job under certain circumstances but everything has moved on, whether you like it or not.
This article reminds me of 'The king is dead, long live the king'; leave VB6 to die and move on to a modern technology. I shan't give you a vote one way or the other since you are entitled to your opinion; however, try being a little less dogmatic, VB6 is dead and it ain't coming back! For argument's sake I bother to answer. 1) I checked all accounts that made the comments.
None is created after the publication of the this article. 2) votes on CodeProject can not be manipulated.
1 IP + 1 account = 1 Vote 3) well known community contributors do not take you into account. If you have not understood, more than 10% of these reviews are written by well known community contributors. 4) You are one of the trolls from uservoive.com, and the most likely the only one. I do not understand from where do you have so much time and energy for this stuff. 5) where is the 'rubbish' in the article?! 6) where is the 'nonsense' when in 2015 tens of thousands of programmers ask Microsoft for a new version of Visual Basic 6.0? But you know this very well already!
1-All of those accounts are created around the publication date of this article. Highly suspicious. 2-Not really. There are bunch of 5$/month VPN services, where you can have hundreds of IPs in an instant.
Manipulation is easy. 4-I don't know what uservoice is and what trolls you are talking about. You are highly delusional I guess. I have no affiliation with those. 5-Your article is twisting the facts. Your statistics are totally flawed.
The figures on Tiobe does not say VB6 but VB, which is anything related to basic language, like VB.NET (mostly), powerbasic, realbasic etc. So your claim that VB6 is the most searched language on the internet is false and outright lie. Besides those sample programs you put there look quite 1990ish and doesn't impress anyone here.
VB6 was well known to promote bad coding practices, i.e. Spagetti code. That's why many companies switched to.NET years ago. If you goal is to convince Microsoft to create a new version of VB6, they are much smarter than what you think.
I can assure you that only a few hundred active users may have left after 15 years of no support. The best proof came from a recent money raising poll at indigogo.com for an open source VB6 version to raise 150k which barely could raise 3 thousand dollars. So there is almost nobody interested in bringing back VB6. Instead of answering the points I've made, you accuse me of being a troll. This attitude alone shows and proves that your article being far from a scientific research and technical writing is only a complete farce. It only proves the level of your ignorance in the field of computing.
The moderators of CP shall not allow these type of unfounded and ridiculous claims (such as VB6 being the best programming language in 2015 etc.). Unfortunately, articles such as this one affects the overall quality of this site.
'When an article has 100 votes of 5 stars and 130 positive comments' You are escaping answering legitimate questions about vote manipulation. That means there may be a good deal of truth in my initial assumption of possible vote manipulation for your nonsense article.
(Repeat: almost all of the 5 star voters having opened an account with CP just around the publishing date of the article and never ever commenting on any other article since then). It all seems to me that you have a desperate agenda to make Microsoft to bring back VB6. Also CP is a forum where technical articles shall be published for the benefit of all member programmers. There shall be no place for self promoting, self flattering articles with a propagandist agenda such as yours with absolute zero technical value in it. You should get your own blog and could post whatever you want to post over there.
End of Story! Sreenadh OG 8-Jul-15 21:33 8-Jul-15 21:33 Hi, I am a person who leads a team which develops commercial applications for desktop, web, and mobile platforms. For Desktop we still use VB6 (And do not plan to move away from it, since Microsoft support for at least 8+ years, throughout the life span of Windows 8 for VB6 is confirmed).
For Web we use PHP with Databases MySQL/MariaDB/SQLite3 and do not plan to move away from the same in near future. PHPDesktop also attracts my attention. For Mobile we use Android development platform and PhoneGap along with SQLite3 DB. The point is, I don't find a viable, easy to use, easy to develop application development platform for Windows other than VB6 even now. With VB6 developed commercial applications we can be tension free that it will run smoothly in all windows platforms with little or no troubles. The same cannot be said about cumbersome.Net platform and applications. I also keep an eye on viable VB6 alternatives, but yet to find one.
Thanks and regards, Sreenadh OG. Hugo Lalumiere 29-Jun-15 11:47 29-Jun-15 11:47 Here's a tip: if you think VB6 is good in 2015, you are not qualified to write an article about it.
VB6 was a huge pile of hacks, and applications written in it are unmaintainable messes of spaghetti code for the most part. Yes it was nice back when the only other alternative was MVC, but today, the only good reason to still be using VB6 is to maintain an existing application that has not yet been updated. Anything else is foolish and unbecoming of a programmer worth the name. Nick Koumoutseas 10-Feb-15 2:51 10-Feb-15 2:51 Without support and enhancements, I have been looking elsewhere. My livelihood depends on 4 VB6 programs which by the way have always run with great speed and simply outshine any performance offered by C# or any CLI language.
Today, I still update my 4 'COM' programs and otherwise am moving to the MEAN stack. So Long old friend; if you change your mind, you better do it quickly.
