I 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?
View 3 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.

I have a website that has highly granulised access and hence requires many web.config files. The problem is I would like to trim the menu so that only certain users will have access to certain folders. I have enabled trimming and setup roles in the sitemap, however when I access the page the menu is not show, as I am authorized to view the default page which is not in a subfolder. When I type the url of a page in sub folder's I have access.
How should I handle this:
A site map for each web.config file - don't know how this will work Removing the sub web.config file to only use a single one

I'm developing an application to help law enforcement retrieve and analyze logs and other files left by the use of Pidgin (a multi-protocol messenger client). Right now I'm nearly done, but I want to add the ability to search chat logs for user-defined words or phrases and I don't even know where to begin.
Chat logs are stored as html documents in a folder/sub-folder/sub-folder/sub-folder fashion, where each sub-folder can have dozens of sub-folders inside of it, and the final sub-folder can have dozens if not hundreds of chat logs. If anybody could point me in the right direction, I'd be very grateful.
(Also, this is the first program I've written since about 2005, and I'm essentially teaching myself VB as I go. If you'd like to see what I've cobbled together so far, you can find the program here.)
I'm trying to copy multiple excel source files into one excel file. My current code is working only for 3 source files..If more than 3 files are there, it doesn't copy the data but creates blank work sheet in the output excel file. Lets say I have a source folder with 5 excel files. Each workbook contains one worksheet with data. It copies upto 3 worksheets along with data into output excel file.
Lets say excel1 contains A as work sheet, excel2 contains B as work sheet ,excel3 contains C as work sheet ,excel4 contains D as work sheet ,excel5 contains E as work sheet .Now my output excel file should look like..OutputExcel with A, B, C, D, E along with respective data.But my current code is giving output as A,B,C worksheets along with respective data but its creating blank sheet1,sheet2 in place of D & E.

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.
