Prev: IE crashes when downloading .pdf files
Next: strange problem with HTTP Accept Encoding in my IE
From: Mltwwlco on 31 Oct 2007 15:44
I still am unable to have Internet Explorer 6 launch an external program
when a link to a TIF file is clicked, I still get a blank IE window with a
red X indicating it is unable to display the graphic. Windows Explorer is
setup to open .TIF files with the Windows Picture and Fax viewer, so the
file association is working correctly.

Here are the steps I performed this morning, all without fixing the issue:

0. Performed Systate Backup and copied Repair directory so I have registry
backups

1. Ran regsvr32 /i shimgvw.dll

2. Checked and fixed associations
Before
Assoc .tif=ft000001
Assoc .tiff=.tiff=TIFImage.Document
After
.tif=TIFImage.Document
.tiff=TIFImage.Document
ftype TIFImage.Document
TIFImage.Document=rundll32.exe
C:\WINDOWS\system32\shimgvw.dll,ImageView_Fullscreen %1


3. Deleted [HKEY_CLASSES_ROOT\ft000001] and
[HKEY_LOCAL_MACHINE\SOFTWARE\Classes\ft000001]
Removed ""ft000001"=hex(0):" from the following registry key:
[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts\.tif\OpenWithProgids]
"TIFImage.Document"=hex(0):
"MSPaper.Document"=hex(0):
"ft000001"=hex(0):

4. Updated antivirus software and Sun Java VM to same as other office
computers

5. Checked registry settings for MIME on working computer:
[HKEY_CLASSES_ROOT\MIME\Database\Content Type\image/tiff]
"Extension"=".tiff"
"AutoplayContentTypeHandler"="PicturesContentHandler"
broken computer set to
[HKEY_CLASSES_ROOT\MIME\Database\Content Type\image/tiff]
"Extension"=".tif"
"AutoplayContentTypeHandler"="PicturesContentHandler"
changed extension from ".tif" to ".tiff", rebooted, this did not solve
problem

6. Reviewed thread "Can't see PNG images !" at
http://www.officehelp.in/702646/cant-see-png-images/2 for hints, have not
tried running Systernals Regmon and Filemon yet. Changed IE Security
Settings in Trusted Sites Zone "Open files based on content, not file
extension" from Enable to Disable, rebooted, did not fix issue so reset back
to normal. Note website URL is in Trusted Sites Zone.

7. Tried dragging a saved TIF file on the desktop to an open blank IE
window, got gold bar warning "To help protect your security, Internet
Exploer has restricted this file from showing active content that could
access your computer. Click here for options..." THIS MAY BE THE KEY
DIFFERENCE BETWEEN COMPUTERS, OTHER COMPUTERS DO ALLOW DRAG AND DROP TO IE!
I do not know how to change this setting and determine why Internet Explorer
thinks that a TIF document contains active content on this computer.



PS I am no longer crossposting to Microsoft.Public.WindowsXP.General per Ken
Zhao request.

Good. Thanks for that info. I wasn't sure how far that repair went.

That filetype was probably always there waiting to be used once an
association with its file extensions had been established,
so it might have been sufficient just to replace the assocation by
entering:

assoc .tif=TIFImageDocument
and
assoc .tiff=TIFImageDocument

I don't think that that should have been necessary.
E.g. in the same way that the TIFImageDocument filetype
could have been unused but available, this other filetype
could have remained unused but available (assuming the
software which implements it is still installed.)

In fact running ProcMon to integrate the features of both those tools
would be easier. ProcMon would also allow you to capture both traces
and replay them later in two separate but fully functional ProcMon windows
which would greatly simplify their analysis and comparison.

I'm not sure. I think there is a list of restricted extensions somewhere.
E.g. .exe would be another one. Essentially files which contain binary data
and which might be used directly as payload in buffer overrun "exploits".

But you are seeing that message in the Information bar?
So, according to the following you can then use its right-click menu
and choose Allow Blocked Content? (Assuming trying to do that
doesn't cancel your drag operation, of course. <w>)

http://windowshelp.microsoft.com/Windows/en-US/Help/91b1038d-3f53-43a3-8bd8-9551e7c0b7c61033.mspx

(Live Search for
extension "Internet explorer has restricted this file from showing active content" site:microsoft.com
)

<quote expand="Which messages are displayed in the Information bar">
A webpage being displayed on your computer tried to run a script or ActiveX control.
If you want to allow the control to run, click the Information bar, and then click Allow Blocked Content.

</quote>

Note that that description is specifically about IE7 on Vista but I think that IE6sp2
users may see it (or something similar) too, since the Information bar was an
enhancement introduced with XPsp2.


I just remembered a keyword associated with that list I mentioned above: unsafe

<title>Information About the Unsafe File List in Internet Explorer 6</title>
http://support.microsoft.com/kb/291369

(Live Search for
unsafe extensions site:microsoft.com
)

So if you can figure out where that list is implemented (FWIW I never did
however I don't have any Office products installed either...) then perhaps
you would find .tif and .tiff had been added to it on the problem machine?

Gad. I just remembered I even went so far as to try to install Office Developer
in hopes of finding additional documentation on this "list" but can't remember
how successful that was. I do know that I haven't yet found anything really
useful about it. However, I have never had as much motivation to really
research it as much as you might have now... <EG>

Heh. Perhaps now we should be cross-posting to an Office developer's NG?


Good luck

Robert, the Gold bar warning was a red herring. I dragged the TIF file
from a network drive to IE and after allowing the blocked content to be
displayed, I was back at the red X again. When a file is dragged from a
local hard drive to IE, it immediately displays the red X. Also I doubt
..TIF files are blocked, if the unsafe file list is listed in the registry as
plain text, I would have found it in my past searches.
I tried switching the default program for TIF files from the Windows
Picture and Fax viewer to the Microsoft Office Document Imaging File and
both display the red X.

Ken Zhao / Microsoft, I think Robert did an excellent job with his
suggestions but I would like your assistance again. I can go forward with
the ProcMon, but it will generate quite a bit of data and I will need help
interpreting it. Ken, if you believe that this issue needs to be resolved
in an Office XP newsgroup (or other product like Windows XP where I
originally cross posted), please post this issue there on my behalf and have
them begin troubleshooting so additional days are not lost waiting for a
Microsoft response.
