Re: Question about adding/removing account - C# Discussion Boards

I'm getting an error message

I've gotten a few when trying different things, one is that " the group could not be found (Exception from HRESULT:0x800708AC) " or " The user name could not be found (Exception from HRESULT:0x800708AD ")

Not finding a group or user is only an exception if you then try to use them.

Step through the code and check the values, see what you're really getting back from the searches.

Here is what I found that will work, with this code you can successfully remove a domain account from a local machine

The only problem with this is that I need to somehow enumerate through the names and only try and remove it if it matches a list? And maybe make it so that it is not case sensitive.

removeUser("domain", "group")

public static void removeUser(string domainValue, string adGroupAccount)
{
try
{
string path = string.Format("WinNT://{0},computer", Environment.MachineName);
using (DirectoryEntry dirEntry = new DirectoryEntry(path))
{
DirectoryEntry groupEntry = new DirectoryEntry("WinNT://" + System.Environment.MachineName + "/Administrators,group");

try
{
groupEntry.Invoke("Remove", "WinNT://" + domainValue + @"/" + adGroupAccount + ",user");
groupEntry.CommitChanges();
MessageBox.Show("Account Removed Successfully");
groupEntry.Dispose();
}
catch (Exception cex)
{
MessageBox.Show(cex.Message + "\n" + cex.StackTrace + "\n" + cex.Source);
}

}
}
catch (Exception ex)
{
MessageBox.Show(ex.Message);

}

}

I don't think the username is case sensitive, anyway.

But to run it from a list, you'll have to iterate through the list and call the remove function for each name. As far as I know, there's no built-in way to do it.

You are right, I got a solution working and posted it as a reply to my original thread.

Thank you very much for your help.

It doesn't work because "domain est username" is invalid Smile | :)

. You didn't escape your backslash. Plus, you also generally need 4 backslashes in front:

"\\\\domain\\test username"

Other issues could be your lack of permissions.

Hi,

Thanks for the response, I've added the slashes in front of the domain and the same thing happened, I do have permissions both locally and globally as I'm a local and a domain admin.

Any other thoughts?

Ok ...

Through the help of others here and my own due diligence, this is working now (I don't think you'll need any references added). While searching for an example, I saw many many questions on how to deal with domain accounts and local administrative groups, but no answers so I wanted to post this for googlers to save them some time.

Click for an image of the form

Here is the code on how to run it with a simple form that has 3 buttons and 2 textbox input boxes. Put the group name and the domain into the boxes as so. I've hard coded the group I want to search through (Administrators) so you'll have to change that if you want to search through another group. The user exists is not case sensitive.

private void button2_Click(object sender, EventArgs e)
{
    string domain = textBox1.Text;
    string userName = textBox2.Text;
    try
    {
        AD.ActiveDirectory.addUser(domain, userName);

    }
    catch (Exception ex)
    {
        MessageBox.Show(ex.Message);
    }
}

private void button3_Click(object sender, EventArgs e)
{
    string domain = textBox1.Text;
    string userName = textBox2.Text;
    try
    {
        AD.ActiveDirectory.removeUser(domain, userName);
    }
    catch (Exception ex)
    {
        MessageBox.Show(ex.Message);
    }
}

private void button4_Click(object sender, EventArgs e)
{
    string domain = textBox1.Text;
    string userName = textBox2.Text;
    string result = AD.ActiveDirectory.userExists(userName, "Administrators");
    MessageBox.Show("Exists equals " + result);
}

How is it possible to have a less than a second figure i.e. 0.5 or even less in the timespan.
At present I use every second as follows:
timer.Interval = new TimeSpan(0, 0, 0, 1);

Can I have a smaller figure than 1 in the interval ?
Thanks

Yes: just use the next overloaded constructor: MSDN[^]

timer.Interval = new TimeSpan(0, 0, 0, 0, 1);

Who down voted you for a "thank you"? Compensated.

Looks like whoever it was is a medium rep a***hole. I have countered the downvote you got for that. I wish whoever was targetting Akiboys would just grow up.

I'm not a stalker, I just know things. Oh by the way, you're out of milk.

Forgive your enemies - it messes with their heads

so you are aware of the TimeSpan type and need something from it you haven't needed before. Are you too lazy to look it up yourself? People should just stop answering lazy questions.

I see the sense of humour black-hole as extended its gravity well to the C# forum. Tried to compensate, but not much effect.

hi...
i have released one application..

now i have to maintain the document for the released application..

which is the best method to write the information
such as in word,or pdf or excel or
is there any way to keep the document..?

so that every one should know that the new release
application is released .. and they should be updated

i've hosted the previous application and now i have
release the modules in that application ..

now i have inform all the user that we have
released new modules with etc etc features ..

which is the best way to inform the user about newly released application..?

Send them an email, post a message on your website, etc. I doubt that anyone can guess how you have set up your system, or what interface you have with your customers.

I must get a clever new signature for 2011.

If there is a reasonable amount of information (a page or more of A4 in a normal font size) then PDF. Don't use word: not everybody has a copy, or wants a copy. PDF is portable, free and efficient (none of which can reasonably be applied to Word). Excel is not a good format for release notes, as it's text handling is a bit basic.

Then, I would go with Richard, and email a quick note with a link to the PDF on your website.

What does this has to do with C#?
Confused | :confused:

thanks for replying..

sorry for one more stupid Question

There are two teams hosting team and development team

developers build the software and related document before release

they have the code and document.

now what is the process to that builded project to the hosters i.e hosting department..

means... what are the steps that we should keep in mind

before we give the project to the hosters.....??

I am trying to attach c# application to poker client table window, so i could read visible hand? Can anyone give me idea how to read visible cards.. is it possible behind the code or should i recognize it through recording?

regards

What do you mean by "visible hand"? Does your program control the actual cards on display, or do you mean you want to capture the window image of some other program, and somehow interpret it from a picture? Try and be clearer with your question.

I think he means he wants to look at a web-based game of poker and see what cards are in play. He should be able to pick up his own cards, but I don't think it will help much if he is planning on "enhancing" his chances of winning... Laugh | :laugh:
