Copy Archive To Another Archive Without Deleting Existing Content?
Dec 24, 2011
How exactly do you copy the content of a .rar/.zip file (from your resources) to an archive in the computer? (.jar - Java Archive)I mean without deleting existing data on the .jar file already. I use this code currently.The TestArchive is a .zip file, and when I press the button, it extracts the content of TestArchive to the .jar arhive, but deletes everything that was already inside the .jar archive.[code]...

I'm using jmcilhinney's library (found here), with a few modifications to make it compatible with VB.NET 2008. Using this forum's search feature, I see that it has been noted that SharpZipLib does support adding files to existing archives, but jmcilhinney's library does not implement this feature, and I have no idea where to start in writing my own method.

how would I copy files into a jar, as well as delete folders from that jar. Would I have to decompile it then recompile it? Would sharpziplib do the trick?

I just need to set the archive bit on a file. I see the archive attribute in the FileInfo object which I would think allows me to read the state of the bit, but I'm not sure how I would actually set it.

What I need to know is how to archive UserControl inheritance with VB. I found some samples how to do this with C# and all of them work fine with C#. But when I try to translate this in VB I get an error (namespace not found) in my UserControl-XAML.
E.g. This link, Variant 1: [URL]
It seems to be easy in C# and impossible with VB.
This is my approach:
1) the class "TestBaseCtrl.vb"
Code:
Imports System.Windows.Data
Imports System.Windows.Documents
Imports System.Windows.Input
Imports System.Windows.Media
[Code] .....
Error message:
"The local.TestBastCtrl-type was not found. All assembly references have to exist and all assemblies, that are referenced, have to be built."
It seems to me that the compiler does not find the class in my namespace but I can assure that the namespace is as correct as it is in the C#-project. I need a UserControl to inherit from, there are several functions that should be integrated in all of my forms and I do not want to implement them in every form I want to create. If I get this working, I hope that this kind of UserControls will still be working within the CAL (Composite Application Libary)-Framework, but this will be another story for another day...

i am trying to create from vb.net code a 7zip arhive with password. I did that with winrar :
Dim ret As Long
ret = Shell("c:program fileswinrarwinrar a -ap c: est.rar -ptest c:1.txt c:2.txt")
But the same code doesn't work for 7 zip, i only manage to create the arhive, without password :
Dim ret As Long
ret = Shell("C:Program Files7-Zip7z.exe a c: est.7z c:1.txt")

I was just wondering if anyone had come across this issue before or anything. I just downloaded Visual Studios 2008 professional trial version (ISO) and when I try to run it or open it, I get a "The operation could not be completed. Access is denied." message. I tried doing everything.I disabled my antivirus, uninstalled a previous version of VS 2008, I still get this message.

Im trying to write a program that displays the content of folders to show files and directories using a treeview with images. I have acheived this and the code is below but what i would like to do is to remove all unwanted parts of archives.Display Example.rar and remove Example.rar, Example.r00, Example.r01 or Display Example.rar and remove Example#Part1.rar, Example#Part2.rar
The reason why i am trying to do this is because i am looking to set a loop that will copy or extract files in certain directories but the problem is with partial files is that full extractions are done to each individual part. Say for example there is 10 files to one archive, the extraction is repeated 10 times, for 20 files, 20 full extractions and so on
Imports System.IO
Public Class Form1
Dim tPath = "C:Documents and SettingsAll User"

The program consists of a datagridview with data loaded from our sql server.Once in a great while, the up and down arrows on the scroll bar will be blanked out and I am not able to click on them. When I try scrolling using the scroll bar, the datagridview is resized instead of scrolling.
NOTE: This isn't a program I wrote, just one that I'm using. It was developed with VB 2005 Express, framework 2.0.

I'm working on a school project right now and I have everything fine except this one part of the project: "The audit and errorevent logs should be archived if they are larger than 5K and up you need to keep up to 3 copies of the files." I know how to read and write text files just fine, so I don't need help with that. What I don't know is how to archive a file based on file size, or how to keep up to 3 copies of the files?

in my visual basic 2008 express edition project I have 2 forms (paxreportfrm,paxsearchfrm).I want to give inputs in paxreportfrm and save the record(which is working fine).then in paxsearchfrm i want to search depending on multiple criteria (working ok).when i click on the record which is in gridview in the search form,opens up the paxreportfrm again with all the details of that specific record (working fine). Now i want to update the existing record which has been populated from the gridviw of the paxsearchfrm and also want to have the option to delete the record.I am using the datacontrols(wizard) to make connection with the access2007 database.can someone give me some example of how to do the Edit and delete in the database pls.I already have a save button on the paxreportfrm(if i click on that, after changing the details on existing record, it just saves IT as a new record).so i really need something which will actually save the modifications on the existing record AND ALSO WILL BE ABLE TO DELETE IT FROM THE database. I have tried couple of methods but none of them are working.

I am trying to delete an item from a text file based on if an item appears in a listbox but keep getting an error " Index was out of range. Must be non-negative and less than the size of the collection." The line it is returning the error on is the the first IF statement of the below text.
Code:
Dim Lines As new List(Of String) (IO.File.ReadAllLines("Carl.txt"))
For i As Integer = 0 To Lines.Count -1
If Lines(i).Contains (listBox1.text) Then
Lines.RemoveAt(i)
End If
Next
IO.File.WriteAllLines("carl.txt", Lines.ToArray)
End If

I have a very busy form with 120 textboxes on it. They are all named box1, box2, to box120. this form is a template for 10 other forms. I dont want to create 10 new forms and put all these textboxes on it, so is it possilbe to create a new form; form2, form3, form4 etc...and somehow copy all the content from one form to the other and retain the textbox names. I tried to cut and paste and got some strange errors, then i tried in the solution explorer to copy and past there. I got some odd error about Private components...which i did not understand. As you can imagine with all these forms and 120 textboxes on each to create them is a real effort. Is there not a simpler way?

I saw a post from 3 years ago (copy folder content to other location) that looked like the "state of the art" way to copy a folder was to just copy all the files recursively. Has vb.net 2008 introduced a function to do this? I still dont see a System.IO.Directory.Copy...

I attached a picture of my existing panel with its controls in this thread, how do you copy it during run time? My project is a server/client application. whenever the client is connected and sends information to the server listening that information is displayed in the server but in a new panel with controls the same as the existing panel for the server, only the location and the information displayed is different. It would look something like in the 2nd attached picture.

I would like to make a copy of an existing database in microsoft SQL Server 2005 in code, if that is possible. I'll need to make a copy of the original one, and change the name to some other name choice. All tables, stored procedures and such will be exactly the same.
