2 X listbox multiextended D&D double click + buttons
 

Hi,
i have to listboxes names lbData and lbTo. the idea is the user gets to the form and the lbData gets contact information from the database. the user then selects the user(s) they require and click next to start tyoign a message to them. i need to be able to drag and drop multiple selections between the 2 boxes. i also need to be able to double click and the contact will move to the other box and also having move buttons in the middle for move selection and move all between the boxes.
can anyone help? ive used various guides but they all use different methods and only provide one of the functions.

all help is much appreciated.

Thanks,
Piercy
