This may be a semantical problem that has poped up,
but I would like to uncover any posible side effects...
I have written a small "batch file" program to
do "Some Stuff" (TM) when any disk is changed.
It is called "WaitDiskChange" which halts the execution
of a batch file until a disk is changed, rather than polling
with "wait" command or some other hackish method...
To get the global DISKINSERTED & DISKREMOVED
messages, I opened a 1 pixel window on the WB screen,
this initialises my message port & makes life a little easier.
The only problem I had was if I "run >nil: s:batchfile"
from the user startup or where ever, when it opens
it's 1 pixel window, it stops iprefs/loadwb from doing it's stuff...
Now the solution I found was to do a:
while( ! FindPort("WORKBENCH"))
Delay(50L);
until it found it, Presto !!, no more problems,
UNTIL I tried it on a WB3.1 installation......
WB3.1 doesn't have a port called "WORKBENCH", Hmmmm.....
So I did a: FindTask("Workbench") instead,
as the "Workbench" task exists on both OS versions....
The problem is, it seems a "messy" way of doing this.....
Is there a SIMPLE way of getting a message port up to receive
diskchange messages without opening a window in the first place...
Enclosed is my source code.......
