dear builders,

can someone explain me what i should do if i want my programm to accept Drag 'n Drop
from Outlook Express (for instance: E-Mails or News-posts) or any other application ?

The below function works pretty fine for Drag 'n Drop of files from the Windows Explorer,
but what about other applications ???

Do i need to catch the Drag 'n Drop message of each specific application via:

           BEGIN_MESSAGE_MAP
              MESSAGE_HANDLER(WM_DROPFILES, TWMDropFiles, WMDropFiles);
           END_MESSAGE_MAP(TForm)

I've noticed, Drag 'n Drop of text into my program works from the most applications
that use lke my program the RichEdit control...so why can't I do the same Drag 'n Drop
for other things like: E-Mails from Outlook Express or Thunderbird, etc... ?
