Hi,

I want to override the 'To' button click event in Outlook so that user can

select

a right contact from the list of contact in the organisation other than the

contacts stored in Outlook. Can any one tell me if we can override the 'To'

button click event

using VB so that it would do what we want? If so then how?

Many thnaks!

No. That dialog opening event isn't exposed anywhere. You'd have to use

Win32 API calls and callbacks to handle the dialog window opening and send

it a WM_CLOSE message, then you'd have to provide your own dialog in its

place.

You could handle the PropertyChange() event on the item to trap when a

selection is made from the To dialog, but that would be after the fact.

You don't say what version of Outlook you're working with (always do that),

but the Outlook 2007 object model has a NameSpace method

GetSelectNamesDialog() that is the To, etc. dialog. That can be customized

and set up as you like, but to know when To was clicked you'd still need

what I said in the first paragraph of my answer. There's nothing equivalent

in the earlier Outlook object models. although CDO 1.21 does provide a

Session.AddressBook() function that's roughly equivalent to the Outlook 2007

GetSelectNamesDialog() method.

Please do not multipost.

Hi Ken,

Thank you very much for your help.

I can use WM_CLOSE message to close the To dialog screen. But how can I use

the Win32 API calls and callbacks to handle the 'To' dialog window ("Select

Names") opening?

Our clients use both Outlook 2003 and Outlook 2007. We do like to provide our

own dialog screen for the contact list otherthan Outlook's address book.

Many thanks

Once you know the window hWnd for that dialog you can close it, to respond

to it opening would require handling all Windows messages looking for

creation of that window (the select names dialog). You'd close that and open

your own dialog. Whether that dialog was an ATL form template or a Windows

Form or whatever in whatever language you're using. Since you'd be creating

that dialog from scratch you would be able to handle its appearance and its

return value.

It's not going to be easy or simple, and you'll have to work out most of the

details yourself.
