DB/Reporting :: Enumerating AD Properties From A DirectorySearcher
Apr 17, 2008
I am trying to get the AD Properties from a Search that I do. When I do so I get this as a result "System.DirectoryServices.ResultPropertyValueCollection". How do I get the value? I know that it is a collection but everytime I try I am not successful.
Code:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmdSearch.Click
Dim resEntry As SearchResult
Dim lstItem As New ListViewItem
Dim currentEntry As New DirectoryEntry
[CODE]...

I have an application that resides on a network drive.When the program runs from an XP machine on the desktop or over the network the program works for any user.When it runs from Win 7 on the desktop it works for everyone, but when it runs from Win 7 over the network it fails for users with fewer permissions.Below is the code.It fails on the last line "Dim searchResult As SearchResult = directorySearcher.FindOne"..[code]Can anyone tell me what is missing in the network permissions?

I have a function that searches AD for members of various groups. If I remove the loop, I don't get the error "A column named 'cn' already belongs to this datatable", however, I need to iterate through each OU.
Function getCOMDLNames(ByVal searchStr As String) As DataTable
Dim MySearchRoot As DirectoryEntry = New DirectoryEntry("path", "usr", "pwd")
Dim MyDirectorySearcher As New DirectorySearcher(MySearchRoot)

I have a form which is bound to a table that includes information about properties (real estate). Each property can have a number of inspections. These inspections are included in a separate table.
I want to use the form to show the property information and a data repeater to show all the inspections for that property.I can't seem to get the data repeater to bind to the inspection table and pull only those records related to the property information table. In fact, the data repeater shows nothing.
I can get a data repeater to show all the records in the inspection table when I put the control on its own form, for testing purposes.

If I had 5 text boxes on a form, TextBox1...TextBox5, is there a method to do something like this?
Dim strFld As String
For intFor = 1 to 5
strFld = "TextBox" & intFor
Me(strFld).Text = intFor
Next
It doesn't like the line of Me(strFld) but I figure there must be a way to reference a field via a variable instead of hardcoding the field name.

I was looking for a way to enumerate String types in (vb).NET, but .NET enums only accept numeric type values.
The first alternative I came across was to create a dictionary of my enum values and the string I want to return. This worked, but was hard to maintain because if you changed the enum you would have to remember to also change the dictionary.
The second alternative was to set field attributes on each enum member, and retrieve it using reflection. Surely enough this worked aswell and also solved the maintenance problem, but it uses reflection and I've always read that using reflection should be a last resort thing.
So I started thinking and I came up with this: every ASCII character can be represented as a hexadecimal value, and you can assign hexadecimal values to enum members. You could get rid of the attributes, assign the hexadecimal values to the enum members. Then, when you need the text value, convert the value to a byte array and use System.Text.Encodings.ASCII.GetString(enumMemberBytes) to get the string value.
Now speaking out of experience, anything I come up with is usually either flawed or just plain wrong. Is there any reason not to do it like that?
As pointed out by David W, enum member values are limited in length, depending on the underlying type (integer by default). So yes, I believe my method works but you are limited to characters in the ASCII table, with a maximum length of 4 or 8 characters using integers or longs respectively.

I'm having trouble with program I'm writing for work. It's basically a GUI for some remote management scripts I wrote a while back.I have a listbox (listbox1) to which loads a list of computers from active directory, which works perfectly and quickly.The problem is that I also want to add to another listbox (listbox2) a list of machines 'currently active' on the network. I can't see an easy way to do this in .net but came up with a logical solution.Basically my thought was to 'ping' all of the machines in the directory listing and use the results to make the list...

Is there a way to write a single routine that could enumerate a list regardless of the data type? I am trying to write a custom XML serialization class and it would be great if I could enumerate all items in a generic list the same way, regardless if it was of type String, Integer, etc.

I have some code designed to locate a specific process based off of its window text, gather the main handle, and then all of the child windows. However, I have run into one problem. I cannot seem to gather all the handles and their respective text. For example, when I test my program and do a handle count on the specific process, it tells me that there are more than 400 handles for this one process. How do I get the handle pointers for this process and also gather the text associated with these handles.I have included my source code for reference.
Code:Public Class Form1
Const GW_CHILD As Integer = 5 Const GW_HWNDNEXT As Integer = 2 Const WM_GETTEXT As Integer = &HD Const WM_GETTEXTLENGTH As Integer = &HE Const BM_SETSTATE As Integer = &HF3 Const WM_LBUTTONUP As Integer = &H202 Const WM_LBUTTONDOWN As Integer = &H201

I need to enumerate all the items in an email inbox. However, this code fails
For Each MI As Outlook.MailItem In folderToProcess.Items
'Console.WriteLine("Subject:" + vbTab + MI.Subject)
Console.WriteLine(MI.Subject)
Next
It fails whenever it comes across an item that ISN'T an email (e.g. a meeting request). I've spent the last hour or so trying to find a way of enumerating every item no matter its type. So far all I've come up with is to use the base Object type and then work from there but that's Late Binding and I'd prefer to avoid it if possible.
Has anyone come across this problem before? How can I determine what type of Outlook item it is during enumeration?

As part of my application I am hoping to be able to get the user to enter their IP address and subnet mask which will then enumerate all of the hosts in between which can then be scanned for various open ports/applications installed.
For instance, With a network of 10.91.100.0/255.255.255.252 hosts are valid 10.91.100.1 - .2
How can this be done in vb.net? I would assume also some error checking would need to be put in place to confirm as to whether the subnet mask was valid as well?

I am trying to come up with a good way to enumerate hard disks on remote workstations, possibly including administrative shares, so I can audit key files on them without having to access them via sneakernet.I have domain administrator rights. Security policy prohibits using WMI which would be a great solution.I can retrieve a list of computers using Active Directory, but I need some way to determine what drives are available on each system. Is such a thing feasible? A fellow developer offered some VB6 code from years ago that used WNetOpenEnum, but I was hoping that since we are at .NET framework 4, maybe there's a more elegant / managed way of working with this. I'm keen to use technologies that are more generally supported, such as standard APIs etc. WMI is a great solution but apparently is blocked by default by Windows Firewall, so its availability is not guaranteed.

I have need of either enumerating all the managed threads in a application or listen to when a new thread is created. I can not find anyway to do this through searching the web. It strikes me as odd the the IDE can list all the manage threads, but I can't.
If this is not possible, is there clarification as to why this is not possible.
I need to create a shared class in a DLL that will when it receives a signal will stop all the threads currently running, and gracefully exit the application.

If I change the following line as shown, it works OK:
Code: Dim oMessage As Object
Is this the best way to get it to work or what should I specifically define the variable oMessage as?

I'm making a control and I am trying to finalize my design time properties grid. I have several List(of Class) items as public properties and when I click on the design time menu (while testing the control) there is the word "Collection" and a button with an ellipsis (...) that brings up a neat pop up with the buttons Add/remove and all of the public properties of the collection's class on the right hand side. Basically for a non-collection instance of a class (with public properties) I'd like a similar button to show up. I know I could put all of the properties in the main control class and group them, but I like the pop up box feature. Anyway to duplicate this? (think font grid item etc.)

In the form design I set up a TableLayoutPanel, 20x20 cells and in cell (1,1) a PictureBox (called Target) containing the image of a small target. The properties box for Target shows some very promising properties, Column and Row - and if you overwrite the values in the properties box, the PictureBox obligingly shifts to the corresponding cell position in th design. However in VB it is not possible to refer to Me.Target.Row or .Column - neither appears during coding in the menu of properties, and deliberately coding either of them produces an error like
Error 1 'row' is not a member of 'System.Windows.Forms.PictureBox'.
1. Why does the properties box show properties that cannot be altered programmatically?
2. How can my program move Target around in the TableLayoutPanel?

I'm working on a Hazardous Materials label printing program. One of the options is to do an "NFPA" label. Since there are 4 values required with 4 or 6 options, the ratings are entered via radio buttons in a group box. That's working okay. I display values in the NFPA diamond as they're entered: left quadrant blue, top quadrant red, left yellow, bottom red. I'm having trouble with the label in which the rating will be displayed on top of a jpg diamond for the white. In this quadrant the text can be up to 4 characters. I can accept the text going into an adjacent block a little, but the corners of the label overlap into another quadrant/color. I reduced the font size which solved the overlap problem but the font is then too small and looks terrible. I tried to make the background of the label transparent to let the color come through correctly but that's not a valid value for label.background. I'm figuring that the transparent background is the best solution. What can I use that will accept a transparent background so the color shows through?
I'm trying to set the transparent property via label properties properties, not via code. Here's the code if it makes any difference:
Public Class NFPA
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Close()

Build, reference, component appears in the Toolbox and everything works fine, but the property on the control does not appear in the Properties window when I go to edit it at design time.

I have a BLL class which contains properties for the fields in a Country table (CountryCode, CountryName, etc). It also has a property ioDAL, which is a reference to a DAL class (created with SubSonic 2.2), which has same named fields.
I have a LoadRecord() method which calls the DAL's FetchById() method that populates the DAL properties by calling the database (SQL Server 2005 FWIW).What I then want to do, rather than writing code to populate each BLL property from its DAL equivalent, is to use AutoMapper (from CodePlex). I think the line should be something like
Mapper.CreateMap(ioDAL, Me)()but this gives errors "Value of type (DAL class / namespace naming) cannot be converted to 'System.Type'" and "Value of type (BLL class / namespace naming) cannot be converted to 'System.Type'".
