    <p>In my program I'm reading data from a HTML file, in this file however there are sometimes pieces of text-data containing unicode characters wich get converted back to UTF-8 :</p> <p>Michèle --> Michèle</p> <p>I'm using the following code to retrieve the data from the file : </p> <pre><code> string ConnectionString = string.Format("Provider=Microsoft.ACE.OLEDB.12.0;Data Source={0};Extended Properties=\"HTML import;CharacterSet=UNICODE;HDR=NO;IMEX=1;MaxScanRows=0;TypeGuessRows=0\";", fileName); using (OleDbConnection cn = new OleDbConnection(ConnectionString)) { cn.Open(); using (OleDbCommand cm = cn.CreateCommand()) { string pageName = "bestelformulier"; cm.CommandText = string.Format("Select * from [{0}]", pageName); cm.CommandType = CommandType.Text; var da = new OleDbDataAdapter(cm); var ds = new DataSet(); da.Fill(ds); var dt = ds.Tables[0]; ProcessRows(dt); } } </code></pre> <p>I've searched google trying to find out how to 'tell' OleDb to use Unicode when reading the file but I haven't found a solution yet (using extended property CharacterSet=UNICODE doesn't seem to work). Can anyone here help me out ?</p> <p>thanks, Jurjen.</p> <p>20-mrt-2012, 15.41</p> <p>I have not found a solution but I created a small function te restore the string to it's original state, so that's what I'm using now for all string fields after reading the data.</p> <pre><code> private static Encoding iso = Encoding.GetEncoding("ISO-8859-1"); public static string RepairUTF8(this string value) { byte[] bytes = iso.GetBytes(value); if (bytes.Any(o =&gt; o.Equals(195))) { return Encoding.UTF8.GetString(bytes); } return value; } </code></pre>

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.
