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.
View 3 RepliesHow 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 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?

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

What is the simplest way to check for an existing file. Every method shown to me in my text and the information gained from the Visual Studio help doesn't seem to work. Each one of them tells me the syntax is wrong. I just want a simple way to check for an existing text file that is in the defualt file location.MSDN told me to use FileSystem.FileExists(file) - VS would not take this and...My text Tony Gaddis (VB 2008) shows:
If File.Exists(FileName) Then

View 2 RepliesWhat 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...
When i try to save a file with the same name as the existing file the message box pops up asking me if i want to replace the existing file. When i click yes the program crashes and this message come up An unhandled exception of type 'System.ArgumentException' occurred in system.drawing.dll.[code]
