  displaying mht files Reply Contact I am trying to display mht files that are being generated using ActiveReports.  The code below shows how I am trying to display these to the users. Response.ClearHeaders() Response.ClearContent() Response.AddHeader("Content-Disposition", "attachment; filename=Certificate.mht") Response.WriteFile("Certificate.mht") Response.Flush() Response.Close() If I select Save and save the file to my desktop it can then be opened and display just fine through IE.  If, however, I select to open the attachment it displays the mst file without the images included.  I'm using IE7 on a machine running xp sp3.  The odd part is that the files do correctly open in IE6 (and firefox using the UnMHT addon)  just not IE7.  Is this a bug of some sort or am I doing something wrong?  I don't think it has anything to do with the mht files being generrated by ActiveReports since they open just fine from the desktop.  I have tried setting the content type using both Response.CotentType and Response.AddHeader("Content-Type", ...) but IE seems to ignore these content types if the file has a known extension.  If I set Response.Cache.SetCacheability(HttpCacheability.NoCache) so that there is no cacheing, the content type must then be supplied.  I'm not sure why those are even related.    I haven't been able to find much documentation on this stuff either so any links to that would also be appreciated. Thanks in advance for any replies :)

  Re: displaying mht files Reply Contact We test your code in both IIS6 and IIS7, your issue is recured in our environment. IE 7 cannot decode the image bits to display images which saved by IE6. It is a issue caused by IE7 but not IIS.
