Query Active Directory With OLEDB And Get Over The 1000 Rows Limit?
Mar 5, 2008
You can query active directory with an OLEDB provider called ADSDSOOBJECT. This works great except it only returns the first 1000 rows. The following article shows how to work around this limitation in a vb script by setting the "page size" property of the command object. [URL]..I have been able to reproduce that code in VB.NET, but I am having problems getting it translated to OLEDB syntax, because there doesn't seem to be a "Page Size" property, or indeed a "properties" collection of any kind, in OLEDB.

I have some code that builds a treeview and replicates our AD structure - this runs fine.
One issue i found is when searching through the DirectoryEntries it lists all items where i would like to limit them to Organisational Units only. I thought or using the DirectorySearcher but it seems that i would have two operations running at the same time probably doing the same thing but returning slightly different results just to limit to show what i need. Is there a way to tie DirectoryEntries/Entry with a DirectorySeracher to limit results to Organisation Units or is there a way to do this another way and still have it displayed under a treeview?

Is there any free tool available that can be used to build Active Directry query also can i execute active directry query through c# code because while connecting to active directory through object model and iterating through each property of the active directory specially when all the property is not requierd the performance cost is comming. What I want is to query Active Directory domain get some property value ans save it in the sharepoint list, I am using object model to do this but at the cost of the performance. I am thinking to execute the query through C# code same as any Active Diretory Query tool to pull the value and then save it into the list.

Is it possible (I'm sure it is) to validate a user's credentials against Active Directory without using Directory Services?I'm building a Browser-Based WPF application which requires users to login to and get validated via Active Directory. Since .Net 4.0 (or maybe 3.5) accessing Directory Services from an Application requires the application to be fully trusted. Since IE won't provide full trust to an application if it doesn't have the signing certificate in it's cert store, the application is refused startup permission.
If I don't use Directory Services, then I can leave the application as Partial Trust and validate my user's credentials without having to install a certificate on each user's machine.

I have a data bound datagridview on my form. I need the datagridview to sort by oldest date, and then return only the 150 oldest. The goal is to export the 150 rows with the oldest date to a .csv file and then update the date column to the current date for only those 150.
Here is what I have so far:
Dim appPath As String = Path.GetDirectoryName(Application.ExecutablePath)
Dim tdate As Date
tdate = Today.Date
'sort datelastemailed by oldest to be emailed first
DataGridView1.Sort(DateLastEmailedDataGridViewTextBoxColumn,
[Code] ....
I can get it filter by the column "status" and then sort by "datelastemailed". I can also get it to export only those 150 to the .csv file. My issue is that I need only those 150 to have their date column updated to today's date and then saved to the database. The only way I can see to get that done is to set a max number of rows for my databound datagridview and then loop through each row in the date column. How I can create a filter that limits results?

I have a UI that uses datagridviews / bindingsource / datatables of typed dataset for data entry. The dataset itself is serialized to a varbinary(max) in SQL. (i.e. no tableadapter, backend schema).I would like to limit the number of rows the user can enter into some of the grids (the data is used to fill PDF forms and I don't want them entering more rows than the forms can accomodate.).I have subclassed the datagridview, added a rowlimit property and tried to manipulate the AllUsertoAddRows property
Imports System.Windows.Forms
Public Class dgv
Inherits System.Windows.Forms.DataGridView[code]......
The behavior I see is that the messagebox comes up after leaving the max row even when the user is trying to leave the grid. I can lose the messagebox and deal with notification some other way but I thought someone else may have come up with something a little more sophisticated to handle simply causing attempting to add to many records to navigate out of the grid to the next UI control.

I'm trying to connect and query a .dbf dBase table. I'm fairly certain I've got the connection string formatted properly, because I am no longer receiving errors that I can't locate the table.I've tried everything I can think of, and nothing seems to work to make a valid query. I've tried all sorts of syntax changes around the table name (which is just 'buildings'...nothing fancy). The error is a syntax error with an incomplete query on the executereader line.

I'm having a weird problem with active directory and the display name attribute. I can create an AD account with no problems, the account shows up, I can log on as the account, everything appears to be working as intended. The problem is, our company requires that the display name be in the form of "Lastname, Firstname". Thats all fine and dandy when you create an AD account use the MMC snap-in, you type in the users name as "Lastname, Firstname" in the display name field and when the account is created, the display name shows as "Lastname, Firstname" as you would expect.
The problem I am having is this, whenever I create an AD account programmatically, I can't for the life of me get the display name to show up as "Lastname, Firstname". The displayname property is set as such, checking the AD account using the MMC snap-in shows the display name is set correctly, but when looking at the list of user accounts, the account is always displayed as the users username. The account name I am using is "Test User", see pic below.
if you try to rename the account, the field it tells you it is editing is called Full Name? I can't find a property in AD even called Full Name so I am completely confused, here is a picture of me trying to rename the programmatically created account, as you can see, the display name field is set correctly even though it doesn't display that way. And of course, after renaming the account as seen below, the display name shows up correctly as "Lastname, Firstname"Here is the code I use to create the account, just for reference.
Public Sub CreateActiveDirectoryAccount(ByVal sUserName As String, ByVal sFirstName As String, _
ByVal sLastName As String, ByVal sUserPrincipalName As String, ByVal sPassword As String, _
ByVal sHomeDrive As String, ByVal sHomeDirLocation As String, _

Im trying to connect to AD and carry out some basic tasks for a .Net application written in VB .Net. I would like to create the application so when it loads, it automatically binds to the default AD domain that the user is logged onto. This has led me to writing the code
