This can't be, because the reading is from a socket not a file. I'm reading
from a socket
and writting to a file (in blocks of 10240 bytes). The read does stop when I
abort. This
method would certainly be good if I was reading from one file and ouptting to
another.

The abort routine is not my method, furthermore it does not take any arguments,
it just
closes the socket and thus all data transfering.
The problem I believe is because since my application is GUI and event
driven(OOP), any
action one place jumps you to another section of code, without knowing how to
get back and
say, "hey stop doing that, move on". Does this make sense?

| Subject: [perl-win32-gui-users] Aborting a buffered write
|
| I have a process running, which is writting to a file(using print
| instead of syswrite),
| and I have a small dialogbox with a progressbar and an abort button. The
| problem is when I
| click the abort button, I get a GUI message "select: Bad file descriptor
| at ... line 412".
| This is the line where I read the data in, however, the event for the
| Abort button closes
| the data stream and the file I'm writting to. Plus the title for the
| window error is a
| subroutine which was a far ancestor to where it says the error is. This
| is what the
| Abort_Click looks like.
|
| sub Abort_Click {
| close(FILE);
| $data->abort();
| $ProgWin->Hide(); # <--progress dialogbox window
| $MainWin->SetForegroundWindow();
| $MainWin->BringWindowToTop();
| GUI::Update($MainWin);
| }
|
| I need a way tell the subroutine that is showing the progress to stop
| reading data and
| move on. Any ideas?
