View 16 RepliesI have a web application using VB ASP.NET 3.5 that along with many things allows users to upload documents into a directory on the web server. I would like to know how I can zip a folder on a webserver and download it to the client machine via a submit button.Currently, I have the files displayed as URLs so that the users can right-click and "Save Target As." But I think just having everything zipped in one file would make it alot easier for the users.

Recently I uninstalled and reinstalled Visual Studio 2008. Before that, Visual Studio compress images that I put in the Resources folder. In this folder I put images in PNG format for use in the project. When I was compiling the project, the executable was of a size much smaller than the sum of the bytes of the images as they were compressing in the compilation. The sum of the size of the images gives a 47MB, and the file compiled with the images was around 3.5 MB. But now the images are not compressed. For the resulting executable with the build is about 48 MB ... I'm deducing the problem is because the images were not compressed ...is it so?

View 1 RepliesI'm making a presentation program. It's a bit like PowerPoint, but less complicated and for a different purpose.
All files used in the presentation (like images, texts and sounds) should be put into a single 'file-package'. This package should later be opened by my program, which should be able to use the files from the package. (Just like PowerPoint creates a single file with all images and sounds included, which can be loaded in PowerPoint on a different computer.)
Actual compression for the file is not really needed. It could be sort of like a tar-file.

View 4 RepliesI want to have a backup feature which takes about 7 txt files and compresses/packs them into one file. Then if required at a later stage I can unpack all 7 files from the packed file. I do not need any compression as such just to make one file from 7, then 7 from from that one, if you understand what I mean. I have read there are some native libraries in .NET Framework 2.0 called DeflateStream and GZipStream. Can these be used?

I have a folder with a bunch of different files in it, and I want to display each file name on a line in a single textbox (or block, i don't care) so that the user knows what files are available to be read from. The name and number of files within the folder will change frequently, so making a .txt file with all of the file names wouldn't be an acceptable solution.

View 4 RepliesHow can i encrypt or decrypt only a part of a file? I try, and i keep getting an error message that says that the stream might be corrupt. By the way, it is ok to convert the text to a byte array using the system.text.encoding.ascii.getbytes() right? The reason i want to encrypt/compress only a part of a file is because i don't want to encrypt or compress the file header. That way the program can gather info about whether the file is compressed or encrypted.
View 1 RepliesI have a program I made in vb.net express 2008 that used java.utils.zip to compress my work files to a Zip archive that I ran occassionaly to have a backup. I worked fine, but with net framework 4 and vb.net 2010 it doesn't work. So I modified it to use sharpziplib and it works fine if all files on the filter list in the folder are closed, but if I have a file open in OpenOffice writer, my program can't access it and won't create the zip file. The file that usually stays open all the time is my TODO list, that is updated several times a day , so usually gets printed, and updated( adding or deleting entries), without closing it.
