Hi,
I developed a module wihich creates an excel xml stream and sends it to the browser with a save dialog.
Here is the code:
1.filename = "ExcelWorkbookXY_" + DateTime.Now.Ticks.ToString() + ".xls";
2.Response.ContentType = "application/vnd.ms-excel";
3.Response.Clear();
4.Response.ClearContent();
5.Response.ClearHeaders();               
6.Response.AppendHeader("Content-Disposition", "attachment;filename=" + filename);               
7.workbook.Save(Response.OutputStream);
8.Response.End();

The problem is that after the xml part all of the dotnetnuke html code is added. Any ideas?
workbook.Save is a method of a foreign dll and seems to work fine. I guess its more something about response..
Thanks in advance
Robert

Robert,

You may want to move the Clear, ClearContents and ClearHeaders prior to setting the ContentType as this is probably "cleared".   Also,  have not used the Response.Clear given that I used the ClearContents and ClearHeaders.

So this would result in ...

    Response.ClearHeaders();
    Response.ClearContent();
    Response.ContentType = "applicatio/vnd.ms-excel";
    Response.AppendHeader("Content-Disposition", "attachment; filename=" + filename);
    Workbook.Save(Response.OutputStream);
    Response.End();

Hope this help. -- if it does please let us know!
Paul.

Hi Paul, thanks for your answer! The problem is another one: the Response.End(). Inside a try-catch the dotnetnuke errorpage will be called and added to the xml. With an comment a the right line everythings works fine. Robert

Hi,
the Respond.End() line is the problem.
The command leads to an error. Inside a try-catch the dotnetnuke error-code is called and then added to the xml.
