Hello,
is there anybody who has some code with function CopyFileEx?
I need to copy files with progress bar.

Hi Vlado
I have looked in to this as recently as yesterday :)
A search of the EUForum for "CopyFileEx" reveals some good posts from Matt Lewis
including a nice looking generalised example of it. Unfortunately when I tried
it it crashed on "return PROGRESS_CONTINUE" in the callback but did copy the
file.
So yeah, "me too" 
The trick seems to be using ftpr.e to allow more than 9 parameters to the
callback function. But as I said, I get a Machine Level Exception returning from
the callback.
Speaking of which, does anyone know a way to get more info on a machine level
exception, ie what type, code, registers, etc?

I have some useful code demonstrating this. I'll dig it up when I get
home from work.

If you search for win32ext in the archives I've wrapped the ShFileOperation
Windows function that will let you copy a file and shows the dialog where the
file "moves" from one folder to another.

Hi,
i've tried it, but I always get "A machine-level exception..."
In your win32ext I see only demo with function GetTimeZoneInformation().
Do you have some working example with function ShFileOperation ?

Hmmm...I sent a reply to this yesterday but it never showed up. Maybe I didn't
hit the "send" button.
Anyway, here's an example of using the routine to manipulate temporary files
downloaded to a PC from a host:
-- Now that all files have been transferred loop through each temp file
for i = 1 to length(object_list) do
local_file = local_path & "\\" & object_list[i]
local_temp_file = local_path & "\\~" & object_list[i]
-- If the user did not cancel the update then delete/rename the temp
file
if not cancel_upd then
-- Delete the local file
rtn_seq = SHFileOperation(getHandle(Main), FO_DELETE,
local_file, "",
or_all({FOF_SILENT, FOF_NOERRORUI, FOF_NOCONFIRMATION}), 0,
"")
-- Rename the local temp file to the local file name
rtn_seq = SHFileOperation(getHandle(Main), FO_RENAME,
local_temp_file,
local_file, FOF_SILENT, 0, "")
-- Else the user cancelled the component update
else
-- Delete the temp file
rtn_seq = SHFileOperation(getHandle(Main), FO_DELETE,
local_temp_file, "",
or_all({FOF_SILENT, FOF_NOERRORUI, FOF_NOCONFIRMATION}), 0,
"")
end if
end for
I suggest taking a look at the MSDN docs for this function, it will give you a
better understanding of how to use the routine in win32ext. Here's the link:
