Verify Domain Availability With An If Statement?
Aug 26, 2011
I have a process that I wrote in order to perform an NSLookup and output it to a messagebox. I have all that working, but I need to take it one step further. Some of the pc's this app will be installed on will not be joined to a domain. Can anyone provide any assistance with creating a way to check and see if the pc is joined to a domain and/or the domain is available, and then run the process if the pc is joined to a domain and then not run the process if it isnt. If anyone needs any more info just let me know. Here is the process that I wrote:

I have a function that works perfectly when I attempt to add a user from the same domain into a group of the same domain.
Function AddUserToGroup(ByVal strUserDN As String, ByVal strGroupDN As String, ByVal strGRPDC As String, ByVal strUserDC As String) As Boolean
Dim oUser As DirectoryEntry
[Code]....
The error is actually being thrown on the Invoke line, but as I said earlier, if the user is in the same domain, this works perfectly.

This is in reference to my previous thread :
[URL]
Is there any way to detect if the DNS server is not responding for sure. That is because if I ping the server while my torrent downloads are in progress, I get a "Request timed out".

A colleague of mine is interested in getting the Microsoft Developer Support OLE File Property Reader 2.1 Sample (KB 224351) from the numerous download sites. I was wondering if DsoFileSetup_KB224351_x86.exe is available on any of the MSDN disks or is included with the installation of any Microsoft oftware/applcations from our MSDN subscription. He needs to put it on a private network and downloading exe files is not an option.

I am developing a hotel software product, and one of the features required is to be able to display the room numbers in the hotel, and then the status of them for each day of the month.
I am trying to create something similar to a DataGridView control where at the top the column names are the dates of the month, and to the left is the room numbers as rows. Please see the below screenshot of the function I wish to have. However I do not know what control or function they use to create this grid below (it is from an existing product). I need to not just be able to join multiple cells together when it is the same person in the room for multiple days, but also allow drag and drop ability.
Currently I have a DataGridView control and am able to simulate the below screenshot, however with a datagridview control I am unable to join cells across multiple columns nor allow drag and drop ability between rows.

I have a function to check for internet availability where I use:
My.Computer.Network.IsAvailable
However it only works in my computer. If I install the application in another computer, the check does not work. Does it has anything to do with My keyword?

I'm working on a WinForms solution in VB.NET. It's been a while since I'm mostly a web developper. So what I need to do is to replicate the behavior of Microsoft Office product for the Cut, Copy, Paste and Undo menus and toolbar. Which meens, I need to enable Cut and Copy when and only when there's some selected text on the Form. The Paste menu have to be enabled only when the is some text in the clipboard.
Do you have any ideay about how to accomplish that ? I probably would have to check some event in the TextBox's to check if some text is selected (MouseUp ?). Then in the Enter event, I would check if there's something in the Clipboard to enabled Paste menu..

I am developing an application which will keep track of various information about medical practitioners that are affiliated with my place of work. One thing that we are tracking, is their availability by time of day (morning, afternoon, and evening) for each day of the week (monday - sunday). Additionally we will store an optional comment about the practitioners availability, something like "Does not work during full moon."
The input/display form for this information will be table with days of the week as column headers, and times of the day as row headers. Check boxes will indicate whether the practitioner is available during the specified time.
I am having a hard time figuring out how to store this information in the database. The most obvious solution to create a table with 24 columns (21 for 7 days * 3 times, 1 as the primary key, and 1 for the foreign key referring to the practitioner, and 1 for the comment). Which is a crappy table, but at least it's easy to select and update.[code]....

I have a program that copies files to several servers in succession. If one of those servers is unavailable for any reason, my program hangs for about a minute before it continues on to the next server. Is there a quicker way to determine if the path is available or not?

I've created a little procedure that I use to verify if a value does actually exist. I'm currently using this all throughout my application for things such as verifying if a control's EditValue actually has a value. I was wondering if I have missed any scenarios where a value would not be available, missing, non-existent, blank, etc., and how would I incorporate in my procedure.
Public Function ValueExist(ByRef CheckValue As Object) As Boolean
Try
ValueExist = True
If IsDBNull(CheckValue) Then
ValueExist = False

I have not been able to successfully verify a user with LDAP for an ASP.NET web application. I have done so on our own network against Active Directory, but this is against a server outside of our network that is OID (Oracle Internet Directory).Usually, I use the following code with no problem.
Dim myDirectoryEntry As New System.DirectoryServices.DirectoryEntry("LDAP://1.2.3.4:999/OU=SomeOU,DC=Something,DC=com")
myDirectoryEntry.AuthenticationType = System.DirectoryServices.AuthenticationTypes.Sealing
myDirectoryEntry.AuthenticationType = System.DirectoryServices.AuthenticationTypes.Secure
Try
[Code]...
After that, I haven't been able to find a method to verify a user's log in information with their password and then pull back some information.
