Unzip Function - Receive Download Folder With Files
Oct 26, 2011
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] .....
I have a button when clicked unzips a file in a located folder. This code unzips one filename at a time. What I want to do is unzip all files in a folder at one time.. assuming the folder has been selected and the target folder selected too... The code to unzip each filename is shown below...
I have a web folder e.g. "url..." if I open this address in IE it show me all files which this folder have.I want to download all files but I don't want to hard-code name of files. I know I can get the files with webclient.DownloadFiles(@address,@filename). Is this possible to download all files or at least get the name of files from the web folder?
Looking for log4net.dll - download will not unzip I have been to [URL].. and downloaded both files: incubating-log4net-1.2.10.zip incubating-log4net-1.2.9-beta.zip. Neither one will unzip. I have tried downloading twice and have used WinZip 12 and whatever comes with XP.

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.

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 would like to know if there are some in built functions for the scenario that is described below :
The input is the path of a parent folder. Wat the function must do is , it should list out all the .zip files inside that parent folder.The parent folder can contain any number of subfolders, and the same applies to the subfolders too ..
VB version is not a barricade. Any of the versions VB6 or VS2005 can do. Also is there any other alternative way if there are no inbuilt functions as such.
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.
just as the title says i want to zip/unzip files using vb ocde to make a standalone vb application. I saw a couple out there but didnt really know how to work with them
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?
Is it possible to programmatically zip/unzip files in vb.net? Meaning, not that it will extract the files for the user, but take the files inside the zip and be able to use them in the application?
in the current project im making i've decided to add in some tools, 1 of which is a renamer based of a renamer app that already exists (called scdtoolz), i want to build my own version of it so i can learn some new things, and build a nice GUI version of it.[code]So what i have managed to determine is that the current app scans the folders contents for the CRC32 Checksum, and renames based of that, since the 456.bin's CRC32 Checksum was 2274F80B, and in the text file 2274F80B is found here 'WWF - Rage in the Cage (T-81015)(U)#2274F80B#'So now i have determined game identification is based of the CRC32 checksums, how would i go about coding a similar ap in vb.net?first i need to make the app scan a folder, but how to return crcchecksum? and then rename if check = XXXX? If MD4 sums are easier/simpler i can use those instead, im lookin at a few hash app sources now, so i think i can see how to get the md5 but not the crc32 yet, or how to rename the 2 files and folder based of the text file.
I wrote an application that copies files from Folder(A) into Folder (B) First it checks if the files exists if yes it will copy them and it will over write the them in fodler (B) and is working great , but if I have a file in Folder(B)that is located in a subfolder the file inFolder (A) will not be copied to the new location.
belwo is the code to copy the files if they exist :[code..]
Some programs implement command parameters, Like my favourite computer game - Crysis - has them and windows media player has them.But how could i implement them in VB.NET..I want to have a component of my program built as a seperate exe - so it can be an Optional component.But of course the seperate exe, on load, needs data passing to it.So i need something like Process.start("Componentname.exe", "/StartDL <Suchandsuchastring>)/StartDL will need to call a function, and the string that it uses will be given to the function to initiate a download?
Now I upload update to a share folder inside the company network I have full Permission access & everyone read onlyas any one out side the company can't use the program so there no password on the share folderbut I need now to protect the share folder as I have to use real IP on the database connection to allow the company branch's to access the database
I need a script that will check files in a certain folder (lets call it folder1) against files in another folder (folder2), if there are any new files, or changed files it updates them in folder2.
I have a specific problem that I have not yet found an answer to. Basically I need to pass a list of numbers into a function do some math and return them. I can pass one number at a time without a problem, however when I want to pass in an array I start to have issues. My VB.net code looks like this...
if you could see everthing but the thing I'm having trouble with the Public Shared Function(folder in 'Dim folder As nvironment.SpecialFolder' is the problem)

I wrote a program to download and play AVI files the files are large in size and long time wise. I have the files playing as they are being downloaded but i can't see how long the file is or seek reliably. i was reading that the AVI headers are in the last 512kb of the AVI file *why would't they put it at the start* lol so my question is is there a way to download the last 512Kb of the file i'm downloading. i have the Bytes Read and Length of the file while its downlaoding i'm just not sure where to go from there, or how to do it atleast. If i had the length in time of the Avi file i could set the trackbar to be able to seek properly. or if someone has an idea how i could get the time of the video by using fps and some math i could prob do it that way too but idk how i would tell how i can find how many kb are in the fps i'm sure it changes so think that way is't going to be reliable. how to get the last 512kb would be the best option not sure if it can be done even.
