    <p>Two issues:</p> <ol> <li>Your <code>FileStream</code>, <code>StreamWriter</code>, and <code>StreamReader</code> classes should be inside <code>using { }</code> blocks. They implement <code>IDisposable</code>, so you need to be calling <code>Dispose</code>, and the <code>using</code> block will do that for you. If you do this, that's actually all you have to fix (which I'll explain in a minute). Doing this also means you no longer need to call <code>Close()</code>.</li> <li>At a minimum, call <code>mdi_line.Flush()</code> before closing it. This will cause the buffer to be written to the file immediately.</li> </ol> <p>Calling <code>Dispose</code> on the <code>StreamWriter</code> class autmatically calls <code>Flush</code>, which is why the <code>using</code> block will correct the problem.</p> <pre><code>using (FileStream apt_file = new FileStream(textBox1.Text, FileMode.Open, FileAccess.Read)) { textBox1.Text = textBox1.Text.Replace(".txt", "_mod.txt"); using (FileStream mdi_file = new FileStream(textBox1.Text, FileMode.OpenOrCreate, FileAccess.ReadWrite)) { //lecture/ecriture des fichiers en question using (StreamReader apt = new StreamReader(apt_file)) using (StreamWriter mdi_line = new StreamWriter(mdi_file, System.Text.Encoding.UTF8, 16)) { while (apt.Peek() &gt;= 0) { ma_ligne = apt.ReadLine(); //if (ma_ligne.StartsWith("GOTO")) //{ // ma_ligne = ma_ligne.Remove(0, RMV_CARCT); // ma_ligne = ma_ligne.Replace(" ",""); // ma_ligne = ma_ligne.Replace(",", " "); mdi_line.WriteLine(ma_ligne); //} } } } } </code></pre>

    2. CO@melt: It will work, but you really *should* use the `using` blocks like I depicted. You should just be able to copy and paste that code into your application as a replacement for what's there.

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
