If you don't care for the correctness of the IP then you can simply use this pattern:
\[\d+\.\d+\.\d+\.\d+\]
Otherwise you find a lot of IP validation patterns at www.regexlib.com[^]
You can use Regex.Matches to loop over all IPs found.

Thanks looks like a good answer and I've already rated it so, but can you please tell me more and guide me how can I use this bloody Regex and read what it caught?? Please advise.
Many thanks Greeeeeeeeeeeeg

Well, it's christmas, so here it goes 
string str = "Received: from [76.13.13.25] (... rest of the string)"
string pattern = @"\[\d+\.\d+\.\d+\.\d+\]";
foreach (Match m in Regex.Matches(str, pattern))
{
Console.WriteLine(m.Value);
}
will output:
[76.13.13.25]
[76.13.10.167]
[127.0.0.1]
If you only need the IP then use this pattern: \[(\d+\.\d+\.\d+\.\d+)\] and use m.Groups[1].Value in the inner loop. Results in:
76.13.13.25
76.13.10.167
127.0.0.1

You can use the NextMatch member of the Match class.
Regex re = new Regex();
Match m = re.Match();
while (m.Success())
{
m = m.NextMatch();
}

Ho ho ho fellow coders....
is there a way to convert the following recursion code to read this string value??
String Value = "Section1:Section2\\Section3\\Section4\\Section5\\Section6\\Section7\\Section8\\Section9\\etc";
Sample recursion code =
private void btnFillTree_Click(object sender, EventArgs e)
{
directoryTreeView.Nodes.Clear();
String path = "c:\\Temp";
directoryTreeView.Nodes.Add( path );
PopulateTreeView(path, directoryTreeView.Nodes[ 0 ] );
}
public void PopulateTreeView(string directoryValue, TreeNode parentNode )
{
string[] directoryArray =
Directory.GetDirectories( directoryValue );
try
{
if ( directoryArray.Length != 0 )
{
foreach ( string directory in directoryArray )
{
substringDirectory = directory.Substring(
directory.LastIndexOf( '\\' ) + 1,
directory.Length - directory.LastIndexOf( '\\' ) - 1 );
TreeNode myNode = new TreeNode( substringDirectory );
parentNode.Nodes.Add( myNode );
PopulateTreeView( directory, myNode );
}
}
} catch ( UnauthorizedAccessException ) {
parentNode.Nodes.Add( "Access denied" );
} // end catch
}
thanks in advance for any information

What do you want to do? Do you want to fill your tree view with node parsed from the string?
I'd use a regex for this task and loop over the matches.

Yes I want to fill the tree with the nodes passed from the string.
The string is in the same format as a directory string but I dont know of a way to perform the task that
string[] directoryArray =
Directory.GetDirectories( directoryValue );
is doing?
any thoughts or an example of what you stated?

I'd need a better example string, so I can write a proper regex for it.
Do you have one available?

String Value = "Section1:Section2\\Section3\\Section4\\Section5\\Section6\\Section7\\Section8\\Section9\\etc";
This is a typical example.
the only thing that is constant is Section 1 and Section 2, the rest of the sections vary as far a node levels beneath them etc.
thx again for taking the time to look at this!!

I don't see any recursion in the string, but you may try this pattern:
[^\\]*
To loop over the results please take a look at the topic above yours

This is a cool trick...not sure how it helps me for this but I got it working this way
String strValue = "Section1\\Section2\\Section3\\Section4\\Section5\\Section6\\Section7\\Section8\\Section9";
// [^\\]*
string str = strValue;
string pattern = @"[^\\]*";
foreach (Match m in Regex.Matches(str, pattern))
{
Console.WriteLine(m.Value);
}
much more elegent way of breaking up the string into its pieces.
As far as the recursion is concerned the section values in the above string were just an example.
How would you populate the treeview with this??

Instead of doing a Console.WriteLine you could add the nodes to the treeview inside the loop, for example.

When I run the following code on Vista, it updates the label1.Text on the form with each value in textBox1.Text on every "while" loop. This is how I want it to work.
However, when I run the same code on XP, it waits until the "while" loop is complete then only updates label1.Text with the last value in textBox1.Text. Until then, it stays blank.
Is there a way to make it work on XP the same way it works on Vista?
Thanks!
StringReader text = new StringReader(textBox1.Text);
string line;
while ((line = text.ReadLine()) != null)
{
string cmdline = "c:\\windows\\*.* /y /c /i c:\\temp\\windows_backup";
ProcessStartInfo psi = new ProcessStartInfo(@"xcopy.exe", cmdline);
psi.WindowStyle = ProcessWindowStyle.Hidden;
Process p = Process.Start(psi);
p.WaitForExit();
label1.Text = line;
}
}

Well, your code appears to wait for the process to exit before updating the textbox. Try moving that line label1.Text = line; to the top of the loop. (I'm surprised it works in Vista as it is right now.)

Thanks John. I want the update to happen only after the process exits, so that's fine. The process does indeed exit so I'm not sure why you think it wouldn't work.
|
|
|
|
|
You could call Application.DoEvents() after setting the new text to force an update of the textbox. While I don't like this solution it should still work.
Like John, I'm a bit surprised that it updates on Vista after all with this code.

Thanks Greeg, I'll give that a shot and let you know if it works.

Hey Greeeg, Application.DoEvents() worked!!!
You're great.
And, thanks John for responding so quickly. I did try your suggestion prior to my post and it didn't make a difference.
Thanks again guys!
