    <p>I have a file. Each line looks like the following:</p> <pre><code>[00000] 0xD176234F81150469: foo </code></pre> <p>What I am attempting to do is, if a line contains a certain substring, I want to extract everything on the <em>right</em> of the substring found. For instance, if I were searching for <code>0xD176234F81150469:</code> in the above line, it would return <code>foo</code>. Each string is of variable length. I am using C#.</p> <p>As a note, every line in the file looks like the above, having a base-16 number enclosed in square brackets on the left, followed by a hexadecimal hash and a semicolon, and an english string afterwards.</p> <p>How could I go about this?</p> <p><strong>Edit</strong></p> <p>Here is my code:</p> <pre><code> private void button1_Click(object sender, EventArgs e) { Form1 box = new Form1(); if(MessageBox.Show("This process may take a little while as we loop through all the books.", "Confirm?", MessageBoxButtons.YesNo, MessageBoxIcon.Information) == DialogResult.Yes) { XDocument doc = XDocument.Load(@"C:\Users\****\Desktop\books.xml"); var Titles = doc.Descendants("Title"); List&lt;string&gt; list = new List&lt;string&gt;(); foreach(var Title in Titles) { string searchstr = Title.Parent.Name.ToString(); string val = Title.Value; string has = @"Gameplay/Excel/Books/" + searchstr + @":" + val; ulong hash = FNV64.GetHash(has); var hash2 = string.Format("0x{0:X}", hash); list.Add(val + " (" + hash2 + ")"); // Sample output: "foo (0xD176234F81150469)" } string[] books = list.ToArray(); File.WriteAllLines(@"C:\Users\****\Desktop\books.txt", books); } else { MessageBox.Show("Aborted.", "Aborted"); } } </code></pre> <p>I also iterated through every line of the file, adding it to a <code>list&lt;&gt;</code>. I must've accidentally deleted this when trying the suggestions. Also, I am very new to C#. The main thing I am getting stumped on is the matching.</p>

    1. COWell, which bit is causing you difficulties? Taking the substring? Finding matching lines? Iterating over the file line by line to start with?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
