Using the simple code below, attempting to upload an MPG file causes the browser to display a new page :- "Internet Explorer Cannot Display the Web Page".  Looks like the issue is in Explorer, rather than the code.  I posted some issues to Microsoft regarding this controls operation in IE late last year.

I am using IE7 64 bit.

Yes - it makes no difference - still the same issue

Is the file upload working properly with the other browsers? Anything to do with the maxRequestLength in web.config or machine.config?

Yes

I was going through the event log after my last post and noticed the following

So I added the following system.web setting which solved the problem.  The web site under design won't actually upload large files, I was just testing to ensure only image files would be accepted and though the MPEG was small, but in fact it was 300M - justs shows the worthwhileness of testing!  Thanks for your input.

I just joined this site, and am working on similar issues.  I have already incorporated all the suggestions in this thread, and in addition, am displaying an image prior to uploading using javascript.  This seems to work fine in IE 6, but not IE 7.

<script language="javascript"  type="text/javascript">
function showBrowse(pFile, idx)
{
imgThumb = eval("document.images.img" + idx);
    imgThumb.src = pFile;
}
</script>
...

 <asp:FileUpload ID="PhotoFile0" runat="server" onchange="showBrowse(this.value,0);"  />

 <img id="img0" alt="imgQ0" height="48" width="64" src="../Images/bg/spacer.gif" runat="server"/>

Just to be clear, what exactly are you seeing?  If the error message is ambiguous (i.e. "this page cannot be displayed"), make sure you've turned off "Friendly error messages" in Tools->Internet Options->Advanced so you can see the real error.

Turned off the "Friendly error messages" and found no error.  I have been checking these file upload pages on various browsers and found that on Netscape 8.1 if I do the

• - type about:config in the addressbar
  - type security.checkloaduri
  - doubleclick the value found to be set to FALSE

This works only if I also open the Netscape Security Center and disable ID Theft Protection and Spyware Protection.

Are there other settings in IE 7 that could make it possible to preview images for FileUpload?
