Outlook 2003 - extract multiple image attachments from clipboard

J

Jake

We have been working on a project to extract multiple image files from the
Outlook clipboard when attachments are copied to it. The project works fine
in
all flavors of Outlook but fails in Outlook 2003 .

I understand this may be due to changes made in Outlook 2003.


The following works with previous Outlook versions but not in 2003:

In The ProcessFileContents procedure, even though the FormatETC structure
has been filled correctly, it still returns an error ... with a HResult <>
0.


What changes are necessary to make it work in Outlook 2003?

Thanks

Hello Jake,

I am not a Delphi expert so I will try my best to understand what you want
to do. If I am offset, please correct me.

Since I only found the GetClipboardFormatName method in your code, I assume
you copy the attachment from the outlook and then you use your program to
read it.

According to the error message, it seems that Outlook fill differently in
the FORMATETC structure.

I would like to suggest you use a tool from the CodeProject named ClipSpy
which you could check the Clipboard content.

http://www.codeproject.com/clipboard/clipspy.asp

You could use this tool to check the content you copy from Outlook 2000/XP
and Outlook 2003 to see the difference.

Hope this will be some help!

Sincerely,

Wei Lu

Thanks for the follow-up but it appears that 'ClipSpy' doesn't work in
Outlook2003 either. It appears the data format in Outlook2003 has changed.


Getting data form clipboard after multiple Outlook 2003 attachments
selection.
Here is a piece of code, trying to get data from selected file, let say, N
5:

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
CF_FILECONTENTS = RegisterClipboardFormat(CFSTR_FILECONTENTS);
fetc.cfFormat = CF_FILECONTENTS;
fetc.ptd = 0;
fetc.dwAspect = DVASPECT_CONTENT;
fetc.lindex = 4;
fetc.tymed = TYMED_ISTREAM;

IDataObject GetData(&fetc, &stg) returns the error:

DV_E_FORMATETC - Invalid value for pFormatetc.

In case of

fetc.lindex = -1;
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

GetData returns S_OK, but returned data contains only first selected file.

Your help solving this issue is appreciated.

Thanks

Hello Jake,

The GetData Method only used for the Windows Clipboard.

So far as I know, I did not find any method to access the Office Clipboard.

Since the Windows Clipboard only could contain one thing once, you could
only get the first selected file.

Wei Lu

I am not sure I understand your answer.

This method worked for all versions except Outlook 2003. Also we are able to
copy multiple image attachments from Outlook 2003 and pasted them from the
clipboard into a Word document successfully. So it would appear to me the
data is there in the clipboard.

Hello Jake,

I understanded. Yes, this issue may caused by the different format of the
clipboard information.

Since this information is undocumented, I will need to consult internally
and I appreciated your patience.

Hello Wei,

Yes I have be patient....

However I don't see why it should take so long to get an answer to such a
simple question.

I would appreciate you doing all you can to get someone to provide a
solution.

Thank you.

Hello Jake,

I am sorry that I still did not get the response from the internal group.

Since this issue is about the difference between Office 2003 and ealier
version Office, our internal team may try to find some other resources to
get the information.

Once I get the information, I will provide it as soon as possible. Thank
you for your understanding!

Hello Jake,

Since we did not provide direct support for Delphi, we need to reproduce
this issue in a supported language (i.e. C++, Visual Basic 6, VB.NET, or
C#).

Could you provide a sample of the supported language for us to further
troubleshooting?

You could send the sample to me and I will involve other resources to help
you.

To reach me, please remove the ONLINE in my email address.
