I have a pair of edit boxes in a dialog, and I would like to be able to receive files through these. How would I go about doing this? BTW, I have to be able to know which control was dropped into.

DragAcceptFiles
DragQueryFile
WM_DROPFILES are things you should look for in the platform SDK

i think they're the functions, you tell Windows which "window" you
want to get dropped files and handle the WM_DROPFILES message
which has an array of filenames that are dropped

for your sample, im not sure whether it would work but pass the hWnd
of each edit control to a call to DragAcceptFiles

Yes, I know these, but how would I capture the WM_DROPFILES messages? Are they sent to the edit control, or to the dialog?

oh right sorry.

yes you need to handle the WM_DROPFILES in the WindowProc of the hWnd you sent to DragAcceptFiles.

for edit controls, you will need to call SetWIndowLong, hEdit, GWL_WNDPROC, newwndprocaddress

and in that windowproc you need CallWindowProc, oldwindproc etc

DragAcceptFiles, hWnd, activate
the hWnd you pass is the one that is used for notification

hope that clears it up for you
