View 2 RepliesI'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.

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.

I am using Shell Dll to unzip zip file in vb.net 2005. Following is the code for this.
Dim sc As Shell32.Shell = New Shell32.Shell
Dim srcf As Shell32.Folder = sc.NameSpace(src)
Dim desf As Shell32.Folder = sc.NameSpace(des)

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?

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.

View 5 RepliesI'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?

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.
View 3 RepliesI've spent the best part of the week learning about TCP/IP and sockets but it's really draining my enthusiasm for my project. The basics are simple enough and the MSDN examples are fine and I can put together a simple server/client easily now, but once I start getting into asynchronous connections, threading and all the other stuff, I'm getting bogged down and frustrated. I've followed a dozen tutorials and examples now and they're all too confusing and half of them simply don't work.
I think what's most frustrating is that I really don't wish to become an expert on sockets or TCP, which seems to be the advice on most forum replies. I really want to be getting on with my project which has ground to a halt since I started looking into this. Yes, I know the world isn't always that simple.
So, what I'm looking for is a 3rd party app or some working code that will let me set up a server and multiple clients. All I really want them to be able to do is to send strings to each other, without blocking the application. Really, that's it, just the ability to pass strings back and forth between server and client, preferably in as simple a format as possible - e.g SendMessage(Client,String).

How can I add the file to my project?How can I utilize intellisense to use the methods in the dll?

My intention is if the dll is found, use it. Else ignore it. However, if the dll is not found, the program throw an Invalid OperationException.
