hi ,
I used a listbox for going to the next or previous record .For the savebutton event , I wrote this :

private void btnSave_Click(object sender, EventArgs e)<br />
 {<br />
   ...<br />
   PopulateListBox1();<br />
 }

and For the PopulateListBox1() Function :

private void PopulateListBox1()<br />
{<br />
...<br />
if (ListBox1.Items.Count > 0)<br />
  {<br />
      ListBox1.SetSelected(ListBox1.Items.Count - 1, true);<br />
  }<br />
...<br />
}<br />

thus , the last record is selected .If I want to select the current record when I press the savebutton , How can I do it ?
thanx

You can find the value or text in the list first and then made that selected.

Sorry for the confusion, actually i got confused with dropdwon list control.
Cant you do something like this.

string str = "sometext";<br />
			for(int i=0;i<=listBox1.Items.Count; i++)<br />
			{<br />
				if(listBox1.Items[i].Equals(str))<br />
				{<br />
					listBox1.SetSelected(i,true);<br />
				}<br />
<br />
			}

No sometext is the text what you need to be set as selected in the listbox.

the Items'ListBox1 (e.g. field [name of company])are the same that with the selection of them , I can go to any record of the Table(next or before record ).

Hi,
What i am trying to say is suppose you are having 3 items in your listbox i.e "abc", "mno" and "xyz". And you want to make "mno" as your selected item then what you need to do is put "mno" in place of "sometext". And you are done. Smile | :)

Hello,

in a program i'm writing I need to get a list with the accounts on my computer. (This must be shown in a combobox, but that's a detail). If I select an account I should need to convert them into a WindowsIdentity object. With that object, I then check file access rights...

Kind regards,
Frederik

What exactly is your problem, getting the accounts or converting them to WindowsIdentity objects?

Formula 1 - Short for "F1 Racing" - named after the standard "help" key in Windows, it's a sport where participants desperately search through software help files trying to find actual documentation. It's tedious and somewhat cruel, most matches ending in a draw as no participant is able to find anything helpful. - Shog⁹

Actually both, for now i don't know how to get the users so in mean while i just tested with filling in the username in a textbox. Then i tried to get a windowsIdentity object from that but it failed. The only thing i can do is get the SID from the username.

I want to have a WindowsIdentity object to use in this class: www.codeproject.com/useritems/UserFileAccessRights.asp

So if you could tell me how to get from sid to windowsIdentity or to get a list with users and windowsIdentity objects, it's the same...

There is probably something you could use in System.DirectoryServices.dll. Regarding the second issue I'm sorry but I don't have time at the moment to even scan the article, but hopefully the DirectoryServices namespace might help you a bit.

You might want to look at this article, A Complete Read Only ComboBox[^]

Or search this site for read only comboboxes. This might help you and you won't have to worry about trapping mouse events.

Hope this helps some,

Paul
