I am evaluating user inputs as commands for my application. If the user presses Q, or q, and then hits enter, the application quits and execution terminates. Is there a proper context, or best practices on how to do that? I do not have any resources to release, or anything like that. Should I just use System.exit(0);? Is there a recomm...
This should be a simple one for someone. I just can't figure out how to do it. Upon exiting of my program, I want to hide the main form and make a final "Thank You" form appear on its own, like this: procedure TMainForm.ExitExecute(Sender: TObject); begin MainForm.Visible := false; ThankYouForm.Show; MainForm.Close; end; But wh...
Does anybody know where can I find a list of GetExitCodeProcess' process termination status codes? I've done some search in the internet and haven't been able to find one. I'm receiving a 33102 code from a GetExitCodeProcess call and I don't understand why. I hope getting a description for this error code will help me sorting this out. ...
I'm wondering if anybody knows of a way to conditionally execute a program depending on the exit success/failure of the previous program. Is there any way for me to execute a program2 immediately after program1 if program1 exits successfully without testing the LASTEXITCODE variable? I tried the -band and -and operators to no avail, th...
Greetings all. I'm setting up a cron job to execute a bash script, and I'm worried that the next one may start before the previous one ends. A little googling reveals that a popular way to address this is the flock command, used in the following manner: flock -n lockfile myscript.sh if [ $? -eq 1 ]; then echo "Previous script is s...

I have a program (grabface) that takes a picture of the face of a person using a webcam, and I also have a shell script wrapper that works like this: On the command line the user gives the script the name of a program to run and its command line arguments. The script then executes the given command and checks the exit code. If there was...
I've built a RCP-based application, and one of my users running on Windows XP, Sun JVM 1.6.0_12 had a full application crash. After the app was running for two days (and this is not a new version or anything), he got the nice gray JVM force exit box, with exit code=1073807364. He was away from the machine at the time, and the only thin...
I'm trying to check for an SVN tag existence from a Perl script. So I try calling svn info $url, read exit code and suppress standard output and standard error streams. However, I struggle to do this elegantly (there are probably better ways to ask SVN about a tag, but that's not the point here): my $output = `svn info $url/tags/$tag`; ...
in the C world, a function can return error code to represent the exit status, and use INOUT/OUT parameter to carry the actual fruit of the process. when it comes to xmlrpc, no INOUT/OUT parameter, is there any best practice/conventions to represent the exit status and actual result? the context is i am trying to write an agent/daemon ...
Hi, I have a stored procedure that has an OUT parameter, indicating an error code. If the error code is not 0, then I raise an error DECLARE BEGIN foo (err_code); IF (err_code <> 0) THEN raise_application_error(...); END; So far so good, but here's my question. This piece of code (shown above) is executed by sqlplus, which is...
I'm trying to execute a copy of the Perl interpreter using Java's Runtime.exec(). However, it returned error code 9. After running the file a few times, the perl interpreter mysteriously started to return code 253 with no changes in my command at all. What does code 253 / code 9 mean? A Google search for perl interpreter's exit codes tu...
If in my C# application, I am creating a child process that can either terminate normally, or start misbehaving, in which case I terminate it with a call to Process.Kill().However, I would like to know if the process has exited normally.I know I can get the error code of a terminated process, but what would be a normal exit code and what...

For example calling exit(100) would exit the application with status 100, and calling raise(SIGABRT) aborts the application with status 134 while creating a core dump. But what if I want the core dump with status 100 or any other arbitrary value. How can I do that ? I know there are several signals that triggers a core dump, but they see...

I have a perl script that is run with a command like this: /path/to/binary/executable | /path/to/perl/script.pl The script does useful things to the output for the binary file, then exits once STDIN runs out (<> returns undef). This is all well and good, except if the binary exits with a non-zero code. From the script's POV, it thin...
