Dialog box problem(Recall message)

Hi Gurus !

Some developement in my code for recalling a message.

I am selecting sent message from a listview on a form.
I am able to open the selected message and click recall message button for the selected message.

Now dialog box is coming asking for delete unread copies ............

So i want to access this dialog box programatically.. so that user dont have to do anything with actual outlook.

When the user selects recall this message on my form i should be able to click options in this dialog box programatically....


Thanks...
