    <p>I have a .NET plugin which needs to get the text of the current buffer. I found this <a href="http://sourceforge.net/p/notepad-plus/discussion/482781/thread/90ae2b1a/" rel="nofollow">page</a>, which shows a way to do it:</p> <pre><code>public static string GetDocumentText(IntPtr curScintilla) { int length = (int)Win32.SendMessage(curScintilla, SciMsg.SCI_GETLENGTH, 0, 0) + 1; StringBuilder sb = new StringBuilder(length); Win32.SendMessage(curScintilla, SciMsg.SCI_GETTEXT, length, sb); return sb.ToString(); } </code></pre> <p>And that's fine, until we reach the character encoding issues. I have a buffer that is set in the Encoding menu to "UTF-8 without BOM", and I write that text to a file:</p> <pre><code>System.IO.File.WriteAllText(@"C:\Users\davet\BBBBBB.txt", sb.ToString()); </code></pre> <p>when I open that file (in notepad++) the encoding menu shows UTF-8 without BOM but the <code>ß</code> character is broken (ß).</p> <p>I was able to get as far as finding the encoding for my current buffer:</p> <pre><code>int currentBuffer = (int)Win32.SendMessage(PluginBase.nppData._nppHandle, NppMsg.NPPM_GETCURRENTBUFFERID, 0, 0); Console.WriteLine("currentBuffer: " + currentBuffer); int encoding = (int) Win32.SendMessage(PluginBase.nppData._nppHandle, NppMsg.NPPM_GETBUFFERENCODING, currentBuffer, 0); Console.WriteLine("encoding = " + encoding); </code></pre> <p>And that shows "4" for "UTF-8 without BOM" and "0" for "ASCII", but I cannot find what notepad++ or Scintilla thinks those values are supposed to represent.</p> <p>So I'm a bit lost for where to go next (Windows not being my natural habitat). Anyone know what I'm getting wrong, or how to debug it further?</p> <p>Thanks.</p>

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.
