Hello, how to call eventOnMessage inside onClick Event??
Code: Pascal
[Select]
[+]
[-]
procedure
TForm1
.
EventOnMessage
(
var
Msg
:
tagMSG
;
var
Handled
:
Boolean
)
;
var
NrFiles
,
i
:
Integer
;
Buffer
:
Array
[
0
..
255
]
of
Char
;
begin
try
Handled
:
=
Msg
.
Message
=
WM_DROPFILES
;
if
not
Handled
then
exit
;
attachedSelected
:
=
true
;
NrFiles
:
=
DragQueryFile
(
Msg
.
Wparam
,
$FFFFFFFF
,
Buffer
,
256
)
;
.....
.....
finally
DragFinish
(
Msg

Have you tried to do it standard way?
Code: Pascal
[Select]
[+]
[-]
procedure
WMDropFiles
(
var
Message
:
TMessage
)
;
message WM_DROPFILES
;
I haven't checked, but may be there is existing handler for this message?

Is it healthy for project not to have regular stable releases?
Just for fun:
Code::Blocks, GCC 13 and DOS - is it possible?
