Here is the final code that worked for me. This uses WNetAddConnection2 to establish a connection first, before using DirectoryEntry.
Imports System.Runtime.InteropServices
Imports System.Net
Imports System.DirectoryServices
Imports System.IO
[Code]...
So I moved the code to an ASP.Net web app, which is impersonating a service account through the Impersonate section of web.config. The account I am impersonating does not have admin rights on any of the workstations so I put in a username/password into the constructor for the computer entry like so:
Dim deComputer As New DirectoryEntry("WinNT://" + Computername + ",computer", username, password).The username is that of a domain account which has local admin rights on every workstation. If I look at the Username property of the resulting deComputer object I can see that the username matches what I entered.Also if I enter in an invalid password it throws an error, so it is authenticating in some fashion.
However if I now try and add or remove a user from a remote workstation I get a general access denied error. If I add the service account that ASP.Net is using as a local admin on that workstation it will add and remove no problem.So next I tried using the LogonAPI (advapi32.dll ->LogonUser call) to login as the user account that is a local admin on all workstations, impersonated the resulting WindowsIdentitiy and tried running just the original deComputer instantiation. When I do this every property, excepty Path, returns an OLE exception..

So I've been trying to retrieve a list from sharepoint using Lists() web services and then displaying the list on a datagrid. However I am having some weird problem. My code so far is
'Declare and initialize Lists Web service.
Dim listService As New Lists()
'Authenticate
listService.Credentials = System.Net.CredentialCache.DefaultCredentials
[Code]...
1) It also displays a column called "ows_owsHiddenversion" which I have no idea where it's coming from.2) The order of the columns that are displayed are different from the order in the sharepoint site.3) I have a column called "DONE?" and it is a choice type with the options of choosing 'Yes' or 'No'. But for some reason, in the datagrid, the column under DONE is all blank and I cant figure out why all the 'Yes's and 'No's are not showing up. All the other values for the other columns appear fine.4) I am sorting the data from the sharepoint list by the "Division" column which is fine but the header of the column in the datagrid is labeled "Title". I checked the XmlNode outer and inner xml and for some reason the Field Ref is set to "Title" to represent the "Division" column

I'm looking for a way to get details of the name and status of all services running on a service. I did use the following code:
Public Sub GetServices()
Dim localServices As ServiceController() = ServiceController.GetServices()
For Each service As ServiceController In localServices
If Not String.IsNullOrEmpty(service.DisplayName) Then
dictservice(service.DisplayName) = New Service(service.DisplayName, service.ServiceName, service.Status.ToString)
End If
Next
End Sub
However, since I have packaged up my project as a WCF service, the System.ServiceProcess namespace I used cannot be used: Is there any other way I can retrieve the same details? Possibly through WMI?

How to get a list of processes, work with them, etc. Is that also possible for services like e.g. printer spoiler etc. To get a list of them, close some, start some? If so.. How can I do this.. Just ttell me how to get one services the rest will be obvious as I cant find Even 1 service but I have even made a little task manager with processes. I know that there is a page on MSDN but the API's and other things that are written are not being recognised by vb. Maybe you need a extension to vb? or maybe a API declaration?

I'm looping all the properties in an object via reflection:
For Each p As PropertyInfo In values.[GetType]().GetProperties()
If p.CanRead Then
'Do stuff
End If
Next
how to determine whether the property in question is a generic List(Of T)? If it is I need to loop the list itself.
I've experimented with GetType and TypeOf but have not managed to get anything working.
To clarify, I want to keep this generic. I do not want to specify the type of T, I need to loop the list items and call the ToString method on each item. T could be one of a number of different types (application specific reference types). Is it possible to do this without specifying types?

This program is supposed to allow the user to check items in a checked list box. If the item is checked, it goes into the Completed List Box on the right. The program then adds the unchecked items to the Pending list box on the left. I keep getting placement values (e.g. O,1,2) instead of the strings (e.g. "Key Returned") in the list box results (see photo attached)
Public Class frmCheckOut
Dim i As Integer
Dim cleaning As String = "Cleaning Inspection"
Dim damage As String = "Damage Repaired"

Another program I am working on for fun, I am basically shuffling a list inside a listbox, what I want to do is delete the rest but not sure how to go through with that. At the moment I have this: [code] Just contains the code, declarations outside weren't included.So anyway, once clicked, it will call on the function to basically shuffle in a for loop, I was wondering if I should (or how should) create another function and call it in the click button or have just a loop in the click button so it deletes half the list. What I am doing is I have 20 list of items, I want the program to shuffle the items and then deleting the lower 10, meaning, if I had 10 items and wanted 5 top, I'd want: 0, 1, 2, 3, 4 and deleting 5, 6, 7, 8, 9.

What I am trying to do is connect a sequential text file up to a list view. It displays alright but i have a button which is to add certain details to the sequential text file, but instead of adding it in comma separated variable format, i.e. John,Murphy, etc... horizontally it adds the information vertically downwards, i.e. John

I have an error panel that is subbed in to a page if an error goes wrong to gracefully handle and display errors.Currently, I am just appending the error messages to a string and pushing that to a label. If you have multiple errors, this gets messy.I'd like to push each error to a list item in a bulleted, unordered list.How can I dynamically generate, from a vb codebehind file, new list items inside of an undordered list element?

I have two generic lists, named ListA and ListB. Both ListA and ListB could potentially have duplicate items. What I would like to do is use LINQ to grab the items in ListB that are not in ListA, but I'm unsure how to do so.

First timer here, I love the site!
Running:
- VS 2008
- Sharepoint 3.0
- Access 2007
- Windows Vista (The machine I'm developing it from)
History: (Do excuse me if I don't reference different methods I've taken so far correctly, I'm still learning!) I am building some search software for a law firm that I work for in Australia. It's all coming along really well, but I seem to have hit a snag getting data out of sharepoint lists and into my project!
I first attempted to add a web reference to sharepoint and after a while was able to pull in all of the data from the lists, fantastic!(OR NOT!). The issue then was when I attempted to load it up into an array using XMLNodes, whilst it loaded up fine and I could see all the data, if there was a null value in one of the columns, it wouldn't pull that null value across, therefore, I couldn't really use the data...

I have a List(Of MyObj), and I want to iterate through that list and compare each element to all other elements in the same list, excluding (if possible) the same element. I have a solution that works, but it's slow and uses double For loops. It may possibly have also summoned Cthulhu from his sleep. This below is a sanitized version of what I have:
Dim MyList As New List(Of MyObj)({Obj1, Obj2, Obj3, Obj4, Obj5, Obj6})
If MyList.Count > 0 Then
For i = 0 To (MyList.Count - 1) Step 1

I want to know how to test the 1st list box if it has items more than the other list box but by one item, here is what i have: If lstInvisibleTv. Items.Count > lstInvisiblePc.Items.Count Then it works good if the lstInvisibleTv list box is greater than the other list box by one but it also works if it is greater the other one by one or more which I do not want. I want it to work just by one.

I have a program that will compare an array of grocery list items glist and an array of coupon item clist.When I compare the two and if there is a match somewhere in the array I want to have a picturebox visible.When there is no match, I want the picture box not to be visible. [code] The code seems to work great until I come to the else statement.When the code finds a match it displays the picture box and the msgbox without error, but as soon as the message box is cleared, even though i've input it as an ELSE statement, the picturebox goes false again.Does anyone have any idea of how I can "hold" the picturebox to stay visible while the match between the arrays exists?

i am writing a program that reads a excel report from accounting software with our weeks orders on... so basically the program reads a list of around 100 items which all works fine.I also have a database that holds info on each item, when the excel sheet is parsed the software checks to see if any new items have been added to the list that are not on the softwares database. this is where i am having the issue.I have two lists: ItemsOrdered & ExistsingItems.
All the items ordered this week are in ItemsOrdered and all the items not in the items in the database are in the ExistsingItems list. using these two lists how can i find items that are in ItemsOrdered but not in ExistsingItems.

I have a list (of lines) and i'm looping through them and identifying certain ones as edges; I would somehow like to tag these lines so that when i loop through the list again later, I know which ones i tagged. I hope i'm explaining this ok. if not, let me know. What's the best way to deal w/ this type situation?

I have a List(of String). For example: {"C1", "C12", "C10", "C1", "C6", "C22", "C1", "C6"}. I am trying to write a function to give me a list of duplicates: {"C1", "C6"} in the list. Each duplicate will be listed only once. The function I wrote does give me anything back at all. I can't figure out why. how to translate that syntax into VB.net since I am not up to speed on LINQ yet. It is here: How to get duplicate items from a list using LINQ?

''' Given a List(Of String), returns a list of items that are duplicated in the list.

I've made a program that can add 4 items in a row in a list box, for instance
Item Make Guarentee qty Price
toy car rover 1 1 £45.00
monkey monkey 2 1 £65.00
total: £100.00
The problem is I can't get the price to total up in a lable or textbox, however,I can make it work if i seperate the box and make two, listbox1 for item,make,gtee, qty and listbox 2 for price only.I don't want this because i want the row to delete in one go instead of deleting it from two boxes which is a time taker. code below

I'm learning how to add items from a list box to a combo box. I'm trying to follow what's going on in the function loop and comparing a boolean and selected index. I can see that it's comparing the item chosen to each item already in the combo box to make sure that it's not already there. If function finds that it's not in the list it sends back that it is true that the item is not in the list.
It then continues to the statement that adds item to the list. The code for the double click event is working fine and items are getting added to combo box. However, the code for the add button isn't functional. I'm not seeing why it doesn't work? I coded out the original code, and replaced with something I thought might work but it still isn't functional. [Code]
