I'd like to use WinRAR's dll file to compress files in vb.net.Is there any way this can be done? The only one I found was using the unrar.dll to uncompress files. Also, I'd like to know how to implement WinZIP's dlls to compress files as the zipfldr.dll does not achieve very high levels of compression and encryption.

View 16 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 like to compress the xmldata before the data is provided to the client as an excel file. I am trying to compress and deliver it as a .zip file. its not working Here's my code below. I tried compressing it, converting it to bytes etc etc. The issue with below code is, the XSL transformation is not happening properly and the output excel file is raw xml with some .net exception at the end. (that's what I see on the .xls file that's downloaded at the end) Before I started working on compression my below code was working fine that gives properly formatted excel file from the xml input. the excel file is so nice you can't even tell it was from XML.

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.
