I changed from Close() to End() as suggested and it throws an exception:
ex.Message "Thread was being aborted.". I was using a simple hard coded
string " <html><body><h1>This is some text</h1></body></html>"
The failure to display the HTML, I believe it has something to do with the data
contained inside of the HTML file. If I create a file using the string above, the
output is displayed correctly. Upon viewing the source, it is identical to the
file on disk. No additional headers or information.
The data file I had been using for testing purposes was the Yahoo.com main page.
I just saved it to disk and then read it into a byte[] (see previous message below)
and then do the write. Using this yahoo.htm file instead of the simple html file, I get
nothing displayed. When I view the source code, the following is displayed which
doesn't look like the Yahoo.com file on disk..

Hi, David Elliott,
Are you sure that you are not viewing a cached version of the page? Delete
your temp. files in the IE. If you are running Windows Server (IIS 6.0) you
might need to restart the w3svc service because there is some bizzare
caching which is not documented but many people are experiencing it.
Also, call Response.End() instead of Response.Close()

I added <iframe id=extText runat=server></iframe> to my ASPX page and defined
protected System.Web.UI.HtmlControls.HtmlGenericControl extText;
htmlString = @"ImageFeed.aspx?docId=" + docID;
extText.Attributes["src"] = htmlString;
If I have ImageFeed defined to return:
dataString = @"<html><body><h1>hello world 12</h1></body></html>";
Response.Write(dataString);
Response.Flush();
Response.Close();
Everything works fine.
=======================
If I cache a file
FileStream fs = new FileStream(filename, FileMode.Open);
byte[] data = new byte [fs.Length];
fs.Read(data, 0, (int)fs.Length);
fs.Close();
and have ImageFeed defined to return
data = (byte[])document;
string dataString = Encoding.UTF8.GetString(data);
Response.Write(dataString);
Response.Flush();
Response.Close();
This doesn't work. Using the debugger, I verified that dataString has the
correct information (i.e. the HTML)
If I view the source it returns some generated text from who knows where.
Isn't anything like what I am trying
to load. It looks like this.

Any help would be appreciated.

Hi, David Elliott,
How about an iframe? In the class you can declare it as
System.Web.UI.HtmlControls.HtmlGenericControl, just don't forget the
runat="server" attribute in the .aspx. You can set the attributes (src,
width, height, border, etc) from the property Attributes, i.e.
iframe1.Attributes["src"] = "somepage.aspx";

I need a control on a Web Page that can accept an HTML Document and will
display it.
Any help would be appreciated.
Thanks,
Dave
Here is what I was trying...
protected System.Web.UI.WebControls.Panel htmlPanel;
protected System.Web.UI.WebControls.Image htmlImage;
htmlString = @"ImageFeed.aspx?docId=" + docID;
htmlPanel.BackImageUrl = htmlString;
htmlImage.ImageUrl = htmlString;
htmlImage.Visible = true;
public class ImageFeed : System.Web.UI.Page
{
private void Page_Load(object sender, System.EventArgs e)
{
string htmlData = @"<html><body><h3>Hello World</h3></body></html>";
Response.Write(htmlData);
}
}
