Dropping files onto richedit control (DELPHI 2)?
|
|
| Dos-Man 2004-03-27, 12:21 am |
| Does anyone have experience with writing DELPHI 2 apps
that allow users to drop files onto the richedit control, intercepting
the drop, and opening the file?
I can do this in VB. My knowledge of DELPHI is improving but not
quite as good.

| i will give you a quick run down.
in the Win32 help.
DrayAcceptFiles is used to register what window will be able
to accept a list of strings dropped onto it.
when the action takes place the window will receive the
WM_DROPFILES, in this message is the Handle to a block of strings.
you use the DragQueryFile to obtain one of the items in thelist.
when completed, you use the DrayFinish to release the handle the
windows message pass to your window handler.
now of course you will need either subclass a TRichEdit or
hook into its WndProc to capture this message.

I got this far. When I drop the file onto the Richedit control
the mouse cursor turns into a + sign. But when I release the
mouse, nothing happens.

I'm struggling to handle this message. I only have 2 Delphi
books to refer to!

I will try to hook into its WndProc. Thank you for helping.
