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'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 want to unzip folder and all its contents like sub folder and files. Can I write a program in vb.net 2005 to solve this issue.
View 1 RepliesI 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()

View 4 RepliesI have a .NET customer framework that functions much like a Workflow. It uses reflection to get a listing of all of the processes it is capable of from a specific folder, and starts them via reflection with a known start point (all of them have a method called "Process"). Since these files are only called to do the processing and not part of the compile... is there a way for me to be able to drop in a new reference library (DLL) for one of the processes that is being updated without restarting the whole process?[code]...
View 1 RepliesSay I have a Class Library project with its own .dll.config, and a forms application. I want to confirm that it is impossible to reference the .dll.config file from the .exe.config file and still use My.Settings.
For example: I have SomeClassLibrary project, with SomeSetting that I can access through My.Settings.SomeSetting. I also have SomeFormsApp project. This is what I want my SomeFormsApp.exe.config to look like:
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<configSections>
[Code].....
From my readings, this seems impossible. I either need to copy the content of SomeClassLibrary.dll.config into SomeFormsApp.exe.config, which is tedious and error prone when copying from multiple class libraries, or I need to use ConfigurationManager, which bypasses My.Settings and its typed, Intellisensed goodness.
I am writing an application for editing pdf files with this library: [URL]. The problem is that I had to format pc because a trojan and since that moment every time I try to continue my project I can't use the library. The code its the same as it was before formatting, but when I compile the code and the application runs I get an exception every time I try to use a library function.
Some info:
I'm using visual studio 2008 .net FW 3.5
vb -net language
I'm using a W7 64bit environment (before formating was W7 32bits, but I tried to use a 32bits OS and the problem remains). I've already registered the 2 COM components (Img2PdfAPI.dll and pdprep32.dll)
regsvr32 "C:Program Files (x86)prepToolspdprep32.dll"
regsvr32 "C:Program Files (x86)prepToolsImg2PdfAPI.dll"
Solved: Was because of the license.
I'm attempting to create a little library to encrypt and decrypt Files with AES. There are loads of examples of how to do this on the internet so coding is not a problem. There are however a few questions regarding cryptography and AES in general.
#1 Does the IV need to be kept a secret like the key ?
#2 Can I just hash a string with SHA512 to make a key for AES ? or do I need to use PasswordDeriveBytes ?
#3 In the case of me using PasswordDeriveBytes Do I need to keep the salt a secret ?(or do I need to keep it at all)
#4 Can I generate the IV from the same password that the Key is derived from ?(if so How ?)
My program I wrote is using Outlook 12.0 lib for Outlook 2007. I have referenced this in the project. This exe will only be installed on computers that has Outlook 2007 on it. So with this being the case, do I need to bother including any of the lib files? Or just my exe?I have this in my form:
Imports Microsoft.Office.Interop
Imports System.Reflection
Imports System.IO
Imports System.Text
[code]....
So I assume the Interop is all part of the object lib? I know this sounds crazy but I tried coding it using late-binding with many examples but just had too many problems. So I'm going to make three different exe's for versions 2003, 2007 and 2010.
I am trying to create a sort of code library in visual basic where the form displays a list box of certain project files in vb that i have made in the past and when clicked, launches the .exe files of those visual basic program project files.I know it does not work the same way as writing/ reading text files to vb and it seems as simple as 'on click, launch .exe of selected string "vb program 1" and so on. I am having trouble getting started on this one. Im sorry I cannot provide any starter code bc I only have a basic understanding of in/out text files which wont work the same way with .exe
View 1 RepliesI made a Class Library project that contains the main classes that my Main Project needs because I don't want to main classes when I distribute my project.

how can I prevent the Class Library's files from being opened during my Main Project's debug mode?

View 4 RepliesI 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.
