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.
View 2 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 am trying to write a countdown timer I finally succeeded with MSDN. I get to work whatever I wanted, but this drives me nuts: How can I read and set the volume control? I want, once my timer is run down to zero, read out the current system setting, then play a system sound using
Media.SystemSounds.Exclamation.Play()
Over time I like to ramp up the volume to 80% or until one clicks the Alarm off button (then stop the timer, no sound, and reset volume).
I have a button which reads a comma separated value file and loads it into a richtextbox. Each line contains comma separated chars.
Once the file is loaded in the richtextbox, i want to be able to select specific values from each line and store them into an array.
For example:
Line1: a,b,c,d,e
I want to be able to place only the values "b" and "c" into an array.
I was thinking something like creating a menu for the richtextbox which will be triggered on right click, then highlight the values I want, press right click and select 'place these values in an array'.
it doesn't have to be the way i proposed it, but it definitely must use a richtextbox.

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...
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 have this code to show percentage value of archive extraction. Now it shows 1-100% How do I make it have 2 more digits e.g 01.00-100.00% ? [code]
View 7 Repliesi found out that you can create a Archive but how would i add a password to it?i know this.
Dim di As DirectoryInfo = New DirectoryInfo(Application.StartupPath + "folder")
di.Attributes = FileAttributes.Archive
how to add in the pass now from that code ? or is it a different syntax?
ok if there is any way to open a file from zip archive without extracting it ?

View 3 RepliesQuestion 1: What is the difference between "Background Worker" and "Worker Pool" as indicated within the MSDN samples provided.
Question 2: I noticed while using, AddressOf _Function_, variables cannot be passed; what would be an efficient solution to this?
Question 3: While using multithreading is it required to invoke before setting variables, or only form properties?
Question 4: While using System.Net.Sockets is it safe/efficient to use Application.DoEvents while waiting for new data; or would be using a Do While loop be fine without DoEvents since the action would be multithreaded? Note: there can be up to 2000-3000 sockets in use at a time.

View 4 RepliesIm 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"

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.

In our projects we use setting variables to store user setting for the applications. Moreover, with every latest version of the applications, we upgrade these variables to retain user settings.Normally, this works fine, but recently one of my end user reported an error i.e.Configuration System failed to initialize". The error is related to user.config file. Therefore we requested the user to send us his file.After received the folder, we noticed that it contains 3 files (3begfjb.newcfg,3begfjb.tmp and user. config). 3begfjb.tmp is an empty file, while 3begfjb.newcfg and user.config are identical files. We tried to open these files but the data in user.config isn't proper xml rather its unreadable formatted file.Do any you guys had experienced this sort of issue or any ideas how and what may have created these files and corrupted user.config file.

I have a dictionary object (let's call it _do) I am using to cache some values for use in a multi-threaded program. I have a single controlling parent thread, with a timer function _doTimer() which can kick off child threads with a new instance of class MyThreadObject in each. My parent thread has _do as a property and with each time _doTimer() gets called, it may or may not repopulate _do depending on cacheflag settings. I pass a reference to _do to each instance of MyThreadObject and those threads at some point read the values of _do but DO NOT write to it.
What I want is to ensure that the child threads do not try and read _do whilst the parent thread is writing to it. Same thing but very slightly different -> I also don't want the parent thread to write to _do whilst the child threads are reading from it. However there is no problem with 1 child thread reading the values of _do at the same time as another child thread is reading the values - so ideally I do not want each child thread to completely lock out read access, only locking out Write access.. The code is roughly like this:
