Hi I need to run a batch file from within my application
this is how I do it

uses ShellApi;

...
begin
..
ShellExecute(Handle, 'open', '.\update.bat', nil, nil,
SW_SHOWNORMAL);
end;

It works fine. However the window does not automatically close although it
has been terminated. I have to manually click on the x each time and this is
quite irritating because the file is executed every few minutes.
Any help would be greatly appreciated. Thanks

You can check the "close on finish" box in the properties
(may not be called exactly that, but similar). This would
need to done only once, but potentially on all installations.

IIRC, %windir%/_default.pif specifies the default settings
for DOS boxes. But even so, you may not want this to be the
default. All in all, it's a nuisance alright.

(Perhaps running 'command.com /c update.bat' would work
better. But it's still a kludge.)

1. It seems you run MSDOS programms. Make a pif files for all of them with
checked combo "automatically close when done" in it.
With ShellExecute you need to start these pifs.

2. Or run your programms with command "c:\command.com
<your_msdos_application> /c"

I have used the same things under WIN 95/98, and I don't know what a
behaviour you'll get under NT.

I can answer that, for the same reason I wasn't sure about
the exact caption of that checkbox. NT ruins[0] dos boxes
as console applications, and closes them when done.

[0] That's a typo! I swear that was a typo!

About caption of the check box -- I am using Russian version of Windows :)

I was not sure about NT behaviour in the case when programm has been started
using "command.com". I just checked. In this case it's necessary to run
external msdos programme like with the following:
"c:\winnt\system32\command.com /c <your_msdos_application>".

Or more sensibly:
GetEnvirormentVariable( 'comspec', S[1], Length(S))

If you do not need to see the batch-window:
use SW_HIDE instead of SW_SHOWNORMAL
