In VB.NET and using XP
I am trying to write some code that will let me:
*get an administrator's password
*set an administrator's password
*logout of limited account session
*then login to the administrator account with
the new password
Any information on any one of these four steps would prove useful to me.
Thanks,

You're kidding, right?
Basically, you can't do that. First, there is no function that will return any account passwords, no matter what account your using, even an admin account. Second, in order to change the password of another account, you have to have admin rights.

Hi, Dave how about technology such as third party tool[^] that use to crack or reset password for windows? Why they can reset database but could not change the password if the we know the place where to store the password?
A thousand mile of journey, begin with the first step.

You wil note that that utility you pointed out does NOT run under Windows. Since Windows is not running, the security around the SAM database is also not running. If you we're to attempt to write to the SAM database as a user you would get an Access Denied failure. Reading/Wrighting the SAM database is restricted to the System and Administrators only.
Without running Windows, read/writing the SAM database is just a matter of reading and writing files, if you know the proper format of the file, of course. I've got a UNIX boot CD that does the same thing. No, not on a UNIX system, but will let you edit the registry and clear/change passwords of a Windows XP/NT/2000/2003 machine. All you need is a file system driver that understands NTFS 5 and the proper know-how for reading and writing the registry WITHOUT using registry functions (again, because there is no Windows to do it for you!)
For a project like this, you cannot use C#, Visual Basic, J#, or any other .NET managed language. You can only use raw C++, or any other language that doesn't need a runtime or managed environment.

Yeah, I apologize for not pointing out that i understood quite well that it is a long shot.
Providing that functionality to a developer would cause a major breach in security for the operating system. Anyone working as a programmer for a company that has limited rights to their network could simply write an application to get the admin password.
I am just trying to write a simple application for myself and I was not thinking beyond the scope of my project and of the reasons as to why Microsoft would not supply that kind of functionality. I appreciate the response, I will have to come up with a better solution to project now.
Thanks,
Xadeu

I’m trying to make a peer2peer program which can upload/download several files at the time.
But how do I know witch ports to use???
I use one port to send information for commands, file size, and so on….. port 7070.
The sender program can use any port but the receiver program may not be able to use that port.
How do i resolve that problem?????
And remember, there could be 3 or 5 files to send/receive.
And how do i deal with firewalls and routers???
Please help.

First of all, Don't Panic 
Basicly what you need to do is pretty simple.
First, decide on one port number (for instance 7070 you mentioned), now both peers listen on that port, and both peers know that they are both listening on that port.
When Peer A wants to send a file to Peer B, it creates a new socket (do not bind that socket to ANY port) and connects it to Peer B (by the known port).
Now- Peer B will receive a 'Connection Request', and creates a new socket to accept the new connection.
At this point, Peer A can send asorted information about the file it want to send like size, file name hash etc. and then begin to send the file.
Because this is all happening on different sockets than the listening ones, both peers can initiate any additional number of connection as you wish (well not any number of connections but a reasonable one )
That's it, note that Peer A can also connect and Request a file from Peer B, the possibilities are endless.
I can send you an example project i wrote with all this connection creation working,
i will post it with an article, but it will take some time as i'm on a tight schedule now and can't write the article now.
Let me know if you want the example.

Help I've tried many things to make a list box appear when I write something down
Example
I write an "A" and a list box appears
can anyone help me out?
|
|
|
|
|
Will you explain more about what you want?
Where are you going to press a key? (i.e. on a form, a textbox, etc.)
should the list box be created dynamically at runtime or it can be created in design time and just become visible when you press the key?
Do you mean some kind of shortcut for appearing a listbox?
|
|
|
|
|
hmm what I mean is that when I write a whole word then the list box appears or when I write a letter then the program should read the letter then the list box should appear
By bad for not being much specific first time
|
|
|
|

You still have to describe this better. Are you talking about showing a listbox while type typing in a RichTextBox? Something like IntelliSense in Visual Studio?

First of all, there are two different questions here
1. How to cause the Listbox to become visible when i want to?
very self explenatory, there are two options:
a. create the list box in design-time, with the 'Visible' property set to 'False'
then, when you want it to become visible change the property
b. create the list box dynamically in run-time which i will not explaine here
there are a lot of articles describing this
2. How to "sense" that the somthing specific is being written ?
Well.... basically there is an event fired when a text in a textbox
is changed (there are also a lot of examples on handling events)
handle this event and check what has changed, you can keep a copy of
the content in the textbox, and when it changes compare both copies,
you can scan for the last changed character backwards to see what is written,
there are many possibilities, pick one.
Hope this helps, you are being very vague
next time try explaining what you are trying to do, like "i'm trying the sense when someone is typing a url so i can highlight it".
ok ?

Hi i'm having problems here I made this code but after it finds and p I try to write more stuff but it gets stuck selecting the p. Can anyone help me out here with the codes?
Private Sub Timer1_Tick_1(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick
Try
RichTextBox1.SelectionStart = RichTextBox1.Find("p")
Dim SelectorFont As New Font(RichTextBox1.Font, FontStyle.Bold)
RichTextBox1.SelectionFont = SelectorFont
RichTextBox1.SelectionColor = RichTextBox1.SelectionColor.Black
Catch ex As Exception
End Try

Hi Rylogy!
i'm having problems here I made this code but after it finds and p I try to write more stuff but it gets stuck selecting the p.
You simply forgot to change the length of the selection using the SelectionLength property.
RichTextBox1.SelectionLength = "p".Length
You might also want to use a more generic approach right from the start by supporting strings with any length. A first prototype of a method might look like this:
Private Sub HighlightText(ByVal Highlight As String)
Dim NextPosition As Integer = 0
Do
NextPosition = RichTextBox1.Find(Highlight, NextPosition, _
RichTextBoxFinds.None)
If NextPosition > -1 Then
RichTextBox1.SelectionStart = NextPosition
RichTextBox1.SelectionLength = Highlight.Length
Dim SelectorFont As New Font(RichTextBox1.Font, _
FontStyle.Bold)
RichTextBox1.SelectionFont = SelectorFont
RichTextBox1.SelectionColor = Color.Black
NextPosition += Highlight.Length
Else
Exit Do
End If
Loop
End Sub
The next step would be to replace the hard-coded object RichTextBox1 with an object variable.
Best regards
Dennis
