I am trying to find out how to zip and unzip a file in Visual Basic 2010. I have looked extensively on google and youtube, but found little of use. I was able to run one block of code though:
Sub CompressFile(ByVal filetozip As String, ByVal zipfile As String)
Try
Dim fs As FileStream
[Code]....
but this is not what I need. I am creating a Desktop Screen Capture Program, for personal use, that takes a screen when a set timer ticks (1 min or 60000 milliseconds) and in that timer tick a call to a sub is made, CompressFile( file, compressedfilename). See the problem here? It overwrites the compressed file with the second screenshot. So I need to know how to create a Zip Archive, preferably Not using Gzipstream. I need one that i can open in Winzip or 7-zip. And before you ask, yes I tried to add a reference to the 7z.dll, and error. It does not matter whether the solution to this problem requires outside or inside visual basic, though i ask you ensure it is Virus-Free if it involves downloading.
As there are no zip/unzip functions in vb.net, has anyone figured a way to do this without using any 3rd party components?I was thinking there might be a way to call a shell32 command to gzip.dll, or some other way to use windows native unzip functions?
I have the following Sub which works perfectly fine. However, I want to add an extra function to say that delete the .zip file that has been unzipped. So when it unzips the zipped files it also deletes them. [Code]
I am looking for some help in downloading latest Zip file from a FTP location and UnZIP it by saving to a particular location using VB.NET GipStream or some other method. I prefer not to use any 3rd party controls.
extract a single file (WantedFile.xml) from a .ZIP file (THEBIGZipFile.zip) using native VB.NET Code?I think .NET FW 3.5 or 4.0 has "System.IO.Packaging.Package " which can be used? Not sure. Please advice.
Note: I will not be able to install or distribute any other DLLs like (ICSharp or VJ# or cant use process command to invoke winzip etc).

I've been working on an application that uses TCP to send messages to another computer, but I am going to be updating it alot!I know how to make my program update itself, but I just want a progress bar so you know how long it will take until the file is completely downloaded.Also does anyone know how to zip and unzip files in VB.NET, it would make my updater easier if it can just download a zip file and then unzip it and copy the contents to my applications running directory.

I need to unzip a list of .Z files which will be kept in a folder using Visual Basic.NET. For example, consider that there is a folder like C:FilesToBeUnzipped. Inside this folder there will some 5 to 6 files with .Z as extension. I need to unzip all these .Z files and save the unzipped files in a folder like C:UnzippedDataFiles.
Is this possible in VB.NET? Is there any free component or class library to achive it?

I'm using the System.IO.Packaging namespace in my VS2005 application. The zip compression works fine for 1 or many files. The unzip though for some reason seems to only unzip one file. Initially I did this in vs2008 at home and it worked fine, but now at work with vs2005 it's only unzipping one of the files. Can you see anything that I might be doing wrong?
Public Sub UnzipArchive(ByVal zipFile As String, ByVal UnzipLocation As String) If (Not zipFile Is Nothing And Not UnzipLocation Is Nothing) Then Dim zipFilePackage As Package
I have the following function below, which works fine if you want to Extract a zip file. But, I have a problem, lets take an example, test.zip , which will have a folder within called Download which has txt files. Therefore, when I unzip I receive the Download folder with the files in it. Now, instead I want to unzip the zip folder to create a Test folder and within the Test folder the Download folder which will have all the text files. The function I have does ONLY the Download folder and not the test folder.
Private Sub unzip(ByVal filename As String, ByVal targetdir As String, ByVal overwrite As Boolean, Optional ByVal password As String = "") Dim inputStrm As New ZipInputStream(File.OpenRead(filename)) inputStrm.Password = password Dim nextEntry As ZipEntry = inputStrm.GetNextEntry() [Code] .....
can we unzip a zipped folder using microsoft APIs or namespaces perhaps System.IO.Compression. However, it seems to be cumbersome to use them. With a thrid party dll file it works perfectly fine, however i dont want to use it as we dont know what is actually happening inside. Can we have a piece of code which unzips a zipped folder.

1 List all of the data from Teams.txt in a Listbox. Include suitable headings.
2 List all of the data from Results.txt in the Listbox (use the same Listbox as in 1 above).Include suitable headings. Note that you cannot assume that the file contains onlyresults for the first 3 weeks of the season. Your program should be able to process a results file with more or fewer results.
3 List all of the data from Results.txt in the Listbox. However, in this case the actual team names should be output (your program will need to get this data from Teams.txt. The data should be formatted so that it is aligned correctly. Include suitable headings.
The output might look as follows:
Home Team Away Team Home Team Goals Away Team Goals Bunbury Braves Nedlands Nodders 5 2
