I found that if using ArrayList, all clone/CopyTo/Add command are shadow copy, not separate copy. How can I do such that after an ArrayList A is "copied" to ArrayList B, change in ArrayList A will not reflect to ArrayList B?

What I am doing is iterating through all the groups that belong to the top group (Generic reports). Then I take advantage of the GroupPrincipal.GetMembers(True) which will recurse through a given group name. I test to see if the user exits under that group and if true I put the group name in an arraylist.
I use the for each principal in GroupPrincipal.GetMembers to loop through each returned user to see if they exist.
Is there a way to put all the returned users Principal.Name from a given group in GroupPrincipal.GetMembers into an ArrayList? This would allow me to to use Arraylist1.IndexOf to search for user. Which would be much faster then iterating through a returned list using the for each construct.
Sub RetAllMbrs(strUser As String)
Dim oPC As PrincipalContext = GetPrincipalContext() '<- this is function somewhere else in the code

I am looking for a way to create Volume Shadow Copies of individual files. I have searched accross the net now for classes and code to use but I haven't been able to find anything. I'm only really starting out in .NET and C#, C++ or any other language for that matter are completely alien to me. Everything I've found on the subject, even from Microsoft VSS SDK is either in C# or in C++. I don't want to use any external programs, everything must run from the single exe file.

I'd like a file at "\global\class\VSSClass.vb" that houses all the code needed.
Public objVSSClassObject As New VSSClass
For in-line code I'd like it as streamined as possible as it will be used with arrays of pre-set filenames.
objVSSClassObject.CopyFile(srcFile, dstDirectory)
Here's a sample of how the code would be used.

Dim dstDirectory = My.Computer.FileSystem.SpecialDirectories.Desktop & "\Shadow Files"

in my on the job training i need to develop a program (webinterface in later stage) that is able to work with the volume shadow copy service.after about a month of research i have found about nothing about how to program it using the sdk or something like that.so now im asking on forums if there is anyone who has experience with using it in own programs.so what does it have to do?first i would like to be able to get information about a volume that uses VSS. information like how many copy's were made, when were those copy's created. what files are included in the copy.my prefered langauge is C# but im not affraid to learn (more) about VB or C++
View 1 RepliesI have a bunch of dynamically created controls by the user which I'm storing as a control collection in the session state so I can display them on every postback. Each control that the user generates is a div with other controls inside it. I have a button on each control that will allow the user to either delete the control or duplicate it.

Im getting a constraint error when running the following code. there are four fields set as the primary key on the table: bid number, phase number, phase version, detail number.
It errors out saying that bidno, phaseno, phaseversion are the keys and unique. it does not mention the detail number, but it will error out as soon as i run the line dtDest = dsbid.phasedetail.copy....or, if i use the clone (as in the example below), it errors as soon as i add the row.

I'm writing an Excel file recovery program with VB.Net that tries to be a convenient place to gather and access Microsoft's recommended methods. If your interested in my probably kludgy, error filled, and lacking enough cleanup code it's here: http:[url]..... The basic functionality seems to work although I haven't tested graph macro table recovery yet.
It occurred to me that Vista and Windows 7 users could benefit from being offered a list of previous versions of the file within my application if the Shadow Copy Service is on and there are previous copies. How do I do this?I looked at a lot of web pages but found no easy to crib code. One possibility I guess would be to use vssadmin via the shell but that is pretty cumbersome. I just want to display a dialogue box like the Previous Versions property sheet and allow users to pick one of the previous versions. I guess I could just display the previous version property sheet via the shell by programmatically invoking the context menu and the "Restore previous versions choice", however I also want to be able to offer the list for Vista Home Basic and Premium Users who don't have access to that tab even though apparently the previous versions still exist. Additionally if it possible I would like to offer XP users the same functionality although I'm pretty sure with XP only the System files are in the shadow copies.
I looked at MSDN on the Shadow Copy Service and went through all the pages, I also looked at AlphaVSS and AlphaFS and all the comments. I'm kind of guessing that I need to use AlphaVss and AlphFS and do the following?Find out the list of snapshots/restore points that exist on the computer.Mount those snapshots.Navigate in the mounted volumes to the Excel file the user wants to recover and make a list of those paths.With the list of paths handy, compare with some kind of diff program, the shadow copies of the files with the original.Pull out the youngest or oldest version (I don't think it matters) of those shadow copies that differ from the recovery target.List those versions of the files that are found to be different.This seems cumbersome and slow, but maybe is the fastest way to do things. I just need some confirmation that is the way to go now.
I have an arraylist of integers and I would like to use it in the IN clause of an sql statement:
Dim arrLInt as New ArrayList

This does not work, and I was wondering if anyone knew how to use an arrayList inside the IN clause of an sql statement.

Public maleFirstNames As New ArrayList

Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
I want to declare a set of arraylists and the base values so that they are available throughout the entire program. When I set the declaration for the array list as public and attempt to add a value to the array the add.("john")is underlined in blue and it says end of statement is expected.
I'm trying to do is take each item from an arraylist, that is populated through a structure read from textfiles, then loop through them adding each result from the arraylist to a new line in a textbox. What I'm getting is that it's adding only the last item to the textbox rather than listing them, yes I have multiline set to true. Because of the potential size of the arraylist I have it running in a background worker. Once it's complete then I'm trying to populate the textbox. All the code is working fine to that point it's just populating the textbox correctly is my problem.[code]I've tried adding vbnewline, vbcrlf, cblf at the end of the statement as well as placing the text statement in both the runworkercompleted sub as well as in the delegate with the same result.

Would this be possible? It's important for a project I am working on.

I am using filesystemwatcher and im watching printer spool activities:
Private Sub fsw_Changed(ByVal sender As Object, ByVal e As System.IO.FileSystemEventArgs) Handles fsw.Changed
copyfile????

But, while printers status is spooling the files and size also changing, how can I copy file bytes by bytes?
Something like this:
Dim a As ByteDim b As ArrayList
Private Sub fsw_Changed(ByVal sender As Object, ByVal e As System.IO.FileSystemEventArgs) Handles fsw.Changed

I am having issues adding a custom object to an arraylist at runtime.
Details of what Im trying to achieve.
My object is Fixture which represents a light. My light has the following properties:
Name, isMover, HighlightValue, UserNumber, Channels.
Channels is a dynamic arraylist which lists all the different channels of the fixture. A channel could be the lights colour or its intensity. A channel has the following properties:
Type, FeatureGroup, Value, Universe, Address, Slots and Offset.
Slots is the same again, breaking down to another ArrayList with more details.
Code:
Private Sub Patchingtest()
Dim TestFixture As New Fixture_Structure
Dim Intensity As New Channel

I have a function which iterates through the TextBoxes in my form (and its child controls) and adds each TextBox's name and text to an ArrayList using a structure I called valTxtBox.
Here's a snippet of the
VB.NET
Public Structure valTxtBox
Public nome As String
Public texto As String
End Structure
[Code] .....
Now, the problem is that if I call Clear() for valsTxtBox in the getctrls() function, not all the elements get added to the ArrayList. However, if I don't call Clear() it works just fine. BTW, I'm using VS2008 express which might be relevant.
I am trying to add values from Arraylist to particular column of grid view.
As:
If (Arr_NewContacts.Count > 0) Then
dgvStayout.Rows.Clear() ' **GETTING ERROR HERE**
dgvStayout.Rows.Insert(0, (Arr_NewContacts.Count - 1))
For i As Integer = 0 To Arr_NewContacts.Count - 1
dgvStayout.Rows(i).Cells("Name").Value = Arr_NewContacts(i).ToString

View 9 RepliesIn a Windows Form project (using VB Express 10), is there a way to use a second command line arg (first one is in a module1 for start-up that checks another command line, and if correct, runs app)? This second command line would be used to close the open app (including all forms)? (I already have set up a Module1 to recieve a command line to run the app. This would be a second command to close the running app.)
I am opening the WF app using another app (created in a different software) that can pass command lines. So, if in that other app, I send "close" as a command line arg, how do I set up the WF app to receive this specific "close" command and perform Application.Exit()?
As a beginner using VB, not sure where it would go, how to declare, etc.
I created a Right-Click Menu option for files. When the user clicks the menu option it will copy all of the file paths to the clipboard.The following function I have will retrieve all of the filepaths to the clipboard. The problem lies in adding the filepaths to the listbox. If I turn single instance application off the result is multiple instance of the application for each filepath. Say for example I selected 2 files and clicked my right-click menu, I wind up with 2 instance of my exe with each file path added to the listbox, 1 in one listbox, the other file path in the second instance listbox.
Public Sub getthepath()
Try
Dim thefilepath As String
[code]....
Is there a way to loop through each file path from the clipboard and add them to the listbox through a loop?Several times I have tried different ideas I had that I thought would do it and I got odd results but never a good result.
Any way to add command line arguments to my application so that if someone wants to modify the settings they could run myexe.exe /settings and get the settings form of my application.
