In all likelihood, your best bet is to subclass the window you want it to ac=
cept the files, then filter for the appropriate message. I can dig up some M=
SKB articles on it if you'd like.

Ok, so I managed to tell a window to accept files dragged from the Explorer=20
with the DragAcceptFiles() function (from the shell32.dll).

When I drag the mouse over the window, the mouse pointer changes. When I=20
drop, the window is sent a WM_DROPFILES event.

My problem now is how I should capture this event.

Naive first try: timer which triggers really often. In the event handler I=20
call
   $myWindow->PeekMessage(WM_DROPFILES, WM_DROPFILES)
and if it returns true, I call
   $myWindow->GetMessage(WM_DROPFILES, WM_DROPFILES)

That works like one in ten times or something. Clearly not the way to go.

So, any better way of detecting the WM_DROPFILES event?
