Last example of the chapter, artists.xml and datacontrol2.aspx. Have followed the code in the book and even copied the code from the examples but to no avail. Error message reads:

I am not seeing what the problem is, any ideas?

Is the '@' symbol required?

Tophat · January 26th, 2004, 10:18 PM

The '@' symbol is how it is in the book, whether it is required, I'm not sure.

stu9820 · January 27th, 2004, 10:09 AM

Sorry, the '@' is required.

Here is how the book has it.

<%@ Page language="c#" %>
<%@ Import namespace="System.Data" %>
<%@ Import namespace="System.Xml" %>

<script language="c#" runat="server">
void Page_Load()
{
    string xmlFilename = @"C:\BegASPNET\ch02\artists.xml";
    DataSet newDataSet = new DataSet();
    newDataSet.ReadXml(xmlFilename);
    DataGrid1.DataSource = newDataSet;
    DataGrid1.DataBind();
}
</script>

<html>
<head>
    <title>Data Grid Control example</title>
</head>
<body>
    <asp:DataGrid id="DataGrid1" runat="server" />
</body>
</html>

Note the path in red. Also, did you make it a virtual directory?

We are getting this same error on our page.

What we are doing is running a DTS job in SQL Server that recreates the XML file every five minutes so that a list of news items is "refreshed."

Unfortunately, our users are sometimes hitting that page on our site at the exact same time the XML file is getting re-generated, so they temporarily get the same error you're describing.

Kind of drag but I guess the answer is: don't have the XML file physically open while you're also trying to load it via your code.

What I did was to put it in Inetpub under wwwroot. The line that comes up red for me as an error is: newDataSet.ReadXml(xmlFilename);

Check whether the following syntax of the path is working or not, because the syntax for the path in c# is different

"C:\\inetpub\\wwwroot\\begASPNET_C\\ch02\\artists. xml"

or use the server.mappath option to detect the artists.xml...

Thanks and Regards,
