  • Documenting a Access Application for Developers

    - by Nitrodist
    I need to document a MS-Access application that was created, developed and maintained completely by a power-user over 10 years. This is an interesting situation because what they want is a manual so that a future developer can come in without prior domain knowledge and make changes to the frontend or the backend in a timely manner. There are a few questions on my mind for this little project: What is a good manual design creating application? Microsoft Word doesn't quite cut it. What kind of things would you, the developer, need to know in order to make changes to things like forms, reports, tables or other Access objects? Anything else I missed? Any pitfalls?

  • Are application servers necessary? Advantages of using one? (And other JEE questions)

    - by Mike
    Apologies for the long question.. there seems to be other similar questions on here but none really clear up my confusion. I'd be really grateful if someone could confirm or correct my understanding: Java Enterprise Edition is a set of APIs for building enterprise applications, which take away the burden of developing parts of the system that aren't actually features of the application you are trying to build (i.e. messaging, transactions etc). To do this, you can use an application server, which implements these APIs. So you could use JBoss, Glassfish, WebSphere, WebLogic etc which would provide your application with these enterprise services. However, there are many other implementations of these individual services available such as ActiveMQ for messaging, Hibernate for persistence, OpenEJB etc. You can download these implementations as Java libraries and include them in your application, and use the services they provide in a similar way to using the services provided by an application server. So if my understanding is correct, my questions are: I've read a lot of places that application servers are necessary for JEE features like EJB, but can't you just use an implementation such as OpenEJB and not need an application server at all? Are there any features that an application server provides which you cannot get from another source? Why would/wouldn't I choose an application server over a custom stack such as Tomcat, OpenEJB, ActiveMQ, and Hibernate? Is Spring a complete alternative to JEE? Does it ever require an application server or always just a servlet container? Why would someone choose Spring over JEE? Any help would be much appreciated!

  • starting .net application from command prompt is having issue when path is in SHORTNAME

    - by ioWint
    when we start our .net application using a double click on the explorer or from command prompt where your folder path is proper full name then there is no issue at all. But when you start it from command prompt with the path being a Shortname involving a ~ the application behaves weird. IF is entering condition though the condition evaluates to FALSE in quick watch. Accessing a value of a variable in quick watch and immediate window shows value. but when you use it to assign to another variable in code, it returns NULL / no value. another observation: when you attach Visual studio to debug the app, and when you go about "Set as next statement" visual studio is giving options to select which dll to work up on. i have never seen this prompt before!

  • 'Advanced' Console Application

    - by keynesiancross
    Hi all, I'm not sure if this question has been answered elsewhere and I can't seem to find anything through google that isn't a "Hello World" example... I'm coding in C# .NET 4.0. I'm trying to develop a console application that will open, display text, and then wait for the user to input commands, where the commands will run particular business logic. For example: If the user opens the application and types "help", I want to display a number of statements etc etc. I'm not sure how to code the 'event handler' for user input though. Hopefully this makes sense. Any help would be much appreciated! Cheers.

  • Choosing an Open Source Application Server for J2EE

    - by Rafael
    Hello, I know this may be a recurring topic, but I have read a lot of articles and I still have doubts. Also, I would like to hear more recent opinions about this. The main requirements of my application server are: flexible configuration, support for a extremely high number of concurrent users. It will be a system for the mobile communications industry, so it must have high availability as well. I am going to develop a J2EE application and Open Source Applications Servers are my only option. I have use GlassFish for a very small project and I really liked it. Thank you very much for your advise.

  • Launching a PHP daemon from an LSB init script w/ start-stop-daemon

    - by EvanK
    I'm writing an lsb init script (admittedly something I've never done from scratch) that launches a php script that daemonizes itself. The php script starts off like so: #!/usr/bin/env php <?php /* do some stuff */ It's then started like so in the init script: # first line is args to start-stop-daemon, second line is args to php-script start-stop-daemon --start --exec /path/to/executable/php-script.php \ -- --daemon --pid-file=$PIDFILE --other-php-script-args The --daemon flag causes the php script to detach & run as a daemon itself, rather than relying on start-stop-daemon to detach it. This is how it's (trying to) stop it in the init script: start-stop-daemon --stop --oknodo --exec /path/to/executable/php-script.php \ --pidfile $PIDFILE The problem is, when I try to stop via the init script, it gives me this: $ sudo /etc/init.d/my-lsb-init-script stop * Stopping My Project No /path/to/executable/php-script.php found running; none killed. ...done. A quick peek at ps tells me that, even though the php script itself is executable, its running as php <script> rather than the script name itself, which is keeping start-stop-daemon from seeing it. The PID file is even being generated, but it seems to ignore it and try to find+kill by process name instead. $ ps ax | grep '/path/to/executable/php-script.php' 2505 pts/1 S 0:01 php /path/to/executable/php-script.php --daemon --pid-file /var/run/blah/blah.pid --other-php-script-args 2507 pts/1 S 0:00 php /path/to/executable/php-script.php --daemon --pid-file /var/run/blah/blah.pid --other-php-script-args 2508 pts/1 S 0:00 php /path/to/executable/php-script.php --daemon --pid-file /var/run/blah/blah.pid --other-php-script-args 2509 pts/1 S 0:00 php /path/to/executable/php-script.php --daemon --pid-file /var/run/blah/blah.pid --other-php-script-args 2518 pts/1 S 0:01 php /path/to/executable/php-script.php --daemon --pid-file /var/run/blah/blah.pid --other-php-script-args $ cat /var/run/blah/blah.pid 2518 Am I completely misunderstanding something here? Or is there an easy way to work around this?

  • Launching firefox on remote server causes local firefox to start instead

    - by terdon
    Right, this is strange. I am connecting from my laptop (LMDE) to a remote host (SUSE linux enterprise) using ssh -X. I want to launch a firefox instance running on the remote server so I can have access to webpages on a private network. User@RemoteMachine $ which -a firefox /usr/bin/firefox User@RemoteMachine $ /usr/bin/firefox --version Mozilla Firefox 2.0.0.2, Copyright (c) 1998 - 2007 mozilla.org User@LocalMachine $ which -a firefox /usr/bin/firefox User@LocalMachine $ /usr/bin/firefox --version Mozilla Firefox 14.0.1 Now, if firefox is not running on the local machine, everything goes as expected and executing firefox on the remote machine causes a firefox (v 2.0) window running on the remote machine to show up. However, if firefox is running on the local machine a second window of firefox 14.0.1 running on the local machine appears. I have checked top in both machines. In the 2nd case, a firefox process briefely appears on the remote machine and then disappears when the local version of firefox is launched. My questions are the following: What gives? How/why can firefox connect to its existing instance on the local machine? The remote machine appears to have access to the local machine. It, in fact, appears to have the right to execute programs on my local machine. Am I missing something or is this just weird? Is this not a security risk?

  • EC2 Filesystem / Files stored on the wrong partiton after launching new instance from AMI

    - by Philip Isaacs
    Today I set up a new EC2 Instance from and AMI I created from an older EC2 instance. When I launched the new instance I took the AMI that was on a small instance and launched with a medium instance. From what I can tell this is pretty standard stuff. But here's the stang part. According to AWS these are the differences Small Instance (Default) 1.7 GB of memory, 1 EC2 Compute Unit (1 virtual core with 1 EC2 Compute Unit), 160 GB of local instance storage, 32-bit or 64-bit platform Medium Instance 3.75 GB of memory, 2 EC2 Compute Units (1 virtual core with 2 EC2 Compute Units each), 410 GB of local instance storage, 32-bit or 64-bit platform Okay now here's where I'm having an issue. I when I log into the new bigger instance it still reports only having 1.7 GB of ram. The other strange part is that all my old partitions are still their in the same configurations. I see a new larger partition /mnt which is essential empty. Filesystem Size Used Avail Use% Mounted on /dev/sda1 7.9G 5.9G 1.6G 79% / none 846M 120K 846M 1% /dev none 879M 0 879M 0% /dev/shm none 879M 76K 878M 1% /var/run none 879M 0 879M 0% /var/lock none 879M 0 879M 0% /lib/init/rw /dev/sda2 335G 195M 318G 1% /mnt /dev/sdf 16G 9.9G 5.1G 67% /var2 This EC2 is a web server and I was serving files off the /var2 directory but for some reason the instance is storing everything on / Okay here's what I'd like to do. Move all my website files to /mnt and have the web server point to that. Any suggestions? If it helps here is what my fstab looks like as well. root@myserver:/var# mount -l /dev/sda1 on / type ext3 (rw) [cloudimg-rootfs] proc on /proc type proc (rw,noexec,nosuid,nodev) none on /sys type sysfs (rw,noexec,nosuid,nodev) none on /sys/kernel/debug type debugfs (rw) none on /sys/kernel/security type securityfs (rw) none on /dev type devtmpfs (rw,mode=0755) none on /dev/pts type devpts (rw,noexec,nosuid,gid=5,mode=0620) none on /dev/shm type tmpfs (rw,nosuid,nodev) none on /var/run type tmpfs (rw,nosuid,mode=0755) none on /var/lock type tmpfs (rw,noexec,nosuid,nodev) none on /lib/init/rw type tmpfs (rw,nosuid,mode=0755) /dev/sda2 on /mnt type ext3 (rw) /dev/sdf on /var2 type ext4 (rw,noatime) I hope this question makes sense. Basically i want my old files on this new partition. Thanks in advance

  • "Run As Administrator" on program right click failing and not launching program

    - by GONeale
    This problem lies within a relatively fresh x64 Windows 7 install ~4 weeks, but is also a problem I have seen on Windows Vista machines (x86 versions). Since the other day, any programs attempted to be launched via right clicking on a shortcut (.lnk)'s context menu and pressing - "Run As Administrator" for instance, in the Quick Launch/Jump List in Windows 7 has failed, screen has not dimmed, no UAC popup. In fact the program does not even load. There is no way around this unless I use the shortcut version from "All Programs" which appears to work, very strange? I have performed no major software installs, nothing out of the ordinary. Has anybody encountered this or know what would be causing it? Here's an example of somebody else experiencing this problem in Vista with no solution: http://www.vistax64.com/vista-general/131918-strange-run-administrator-problem.html and I believe this problem is related, I also cannot right click - "Manage" on my computer): http://windows7forums.com/windows-7-support/5501-run-administrator-broken.html I am running the latest version of Avira AntiVir Virus Scanner and pretty concious of what I download, I don't think it is a virus, nor do I believe it is due to the RC Version of Windows 7, because I have seen the problem across multiple Operating Systems versions. Thanks guys.

  • Enter key on Mac OS X renames files instead of launching

    - by Matt
    On my Mac when I hit the "enter" key on a file on my desktop or in the finder, it enters the "rename file" mode. 1) How do you actually "launch" or "open" (i.e. double click) the file with only the keyboard? In Windows, the Enter key does this. 2) Is there a way to map the Enter key to do this in Mac instead of rename? Honestly, it makes little sense to me. I mean, how often do you rename something? Once, maybe. How often do you open something? Lots and lots of times.

  • Shell Script Launching Child Processes

    - by Matt James
    Disclaimer: I'm totally new to shell scripting, but have quite a bit of experience in other languages like PHP and Obj-C. I'm writing my first daemon script. Here are the goals: I want it to run in the background I want it to be triggered by an init.d script that includes start/stop/restart commands I want each process in a loop to trigger its own subprocess. When the parent process kicked off by the init.d script is killed, I want the subprocesses to die as well. Essentially, I'm looking for the same kind of behavior that appears to be very common among software like apache, spamd, dovecot, etc. But, based on my research, I haven't found a single, simple answer as to how this kind of thing is achieved. Any help is greatly appreciated.

  • Launching new Chrome window at a certain screen position (osx)

    - by fad
    I have Chrome open most of the time in the lower right corner of my screen and work mostly with tabs. Sometimes I need a new Chrome window (instance) and hit cmd-n. Now the new window always opens up in the upper left and I have to center it. Is there a way to automatically center new chrome windows (or maybe maximize them..)?

  • Launching Installer Via Powershell and WinRM and Nothing Happens

    - by Nick DeMayo
    I'm currently working on a Powershell script to run some Microsoft Hotfix installers remotely on several Windows Server 2008 R2 servers that I manage. Basically, the script copies all the appropriate files up to the server, and then runs the installer via Invoke-Command, like so: function InstallCU { Write-Host "Installing June 2013 CU..." Invoke-Command -ComputerName $ServerName -ScriptBlock { Start-Process "c:\aaa\prjcusp2\ubersrvprj2010-kb2817530-fullfile-x64-glb.exe" -ArgumentList "/passive" } } If I run the "Start-Process" command locally on the server, the installer runs properly. However, when trying to run it remotely, nothing happens (actually, I can see the installer start up in Task Manager, but it closes a couple seconds later and doesn't run). I've attempted giving the Invoke-Command -Credentials, I've turned off UAC on the server, and I've ensured that my WinRM settings (running 'winrm quickconfig' and setting TrustedHosts to *) are correct. I've also tried having the Invoke-Command script run a local Powershell script to run the installer and changing the Argument from '/passive' to 'quiet' (in case it can't remotely launch something that has a UI), but again, no dice. Is there anything else I can try, or am I just not going to be able to do this?

  • File Not Found error launching Guest OS in a non-administrator user account

    - by ToreTrygg
    Hi, I am running Fusion 2.0.6 (196839) on an iMac running 10.6.2 with 3 user accounts (1 Administrator). I have Fusion set up to share the Guest OS, and it's been working splendidly for nearly a year. Within the Guest OS (Windows XP PRO), there are also 3 user accounts (1 Administrator). Last night I went to back up my VM to an external drive, and to minimize the file size and transfer time, I deleted all Snapshots but the most-recent one. I then backed up the VM externally (28.23 GB). Today, one of my users tried to launch the Guest OS from within her user account, and received the following error message: "File Not Found: Windows XP Pro-000006.vmdk "This file is required to power on this virtual machine. If this file was moved, please provide its new location." My two choices are Cancel and Browse. When I browse, I can locate the Windows XP Pro-000006.vmdk file, which appears to be contained within the VM file (Windows XP Pro.vmwarevm). However, it still won't launch from a non-Admin user account. If I view the package contents of the VM file from the user account, the above file is present and appears to be created upon each launch of the Guest OS. If I go back to my Administrator account on the Mac and then launch Fusion, the Guest OS works perfectly for all 3 user accounts within XP Pro. I have tried to delete the Guest OS from Fusion's Library within the problem user account, then re-connect it to that Library, but the result is the same. The Guest OS data integrity is 100% -- but is accessible only from the OS X Administrator account. This problem only surfaced after deleting several older Snapshots. Again, the data is there, the Guest OS powers up normally in the Mac's Administrator account, but persistently returns the above error when attempting to power on from a non-Admin account on the Mac. I'm not sure how this is affecting the error, but when I look at Hard Disk Settings, the "unable-to-locate" file is the filename of the virtual HD. I don't want to make any changes to my (working) VM without any advice from the knowledgeable people on this forum. Any help will be greatly appreciated, thanks!

  • Script launching 3 copies of rsync

    - by organicveggie
    I have a simple script that uses rsync to copy a Postgres database to a backup location for use with Point In Time Recovery. The script is run every 2 hours via a cron job for the postgres user. For some strange reason, I can see three copies of rsync running in the process list. Any ideas why this might the case? Here's the cron entry: # crontab -u postgres -l PATH=/bin:/usr/bin:/usr/local/bin 0 */2 * * * /var/lib/pgsql/9.0/pitr_backup.sh And here's the ps list, which shows two copies of rsync running and one sleeping: # ps ax |grep rsync 9102 ? R 2:06 rsync -avW /var/lib/pgsql/9.0/data/ /var/lib/pgsql/9.0/backups/pitr_archives/20110629100001/ --exclude pg_xlog --exclude recovery.conf --exclude recovery.done --exclude pg_log 9103 ? S 0:00 rsync -avW /var/lib/pgsql/9.0/data/ /var/lib/pgsql/9.0/backups/pitr_archives/20110629100001/ --exclude pg_xlog --exclude recovery.conf --exclude recovery.done --exclude pg_log 9104 ? R 2:51 rsync -avW /var/lib/pgsql/9.0/data/ /var/lib/pgsql/9.0/backups/pitr_archives/20110629100001/ --exclude pg_xlog --exclude recovery.conf --exclude recovery.done --exclude pg_log And here's the uber simple script that seems to be the cause of the problem: #!/bin/sh LOG="/var/log/pgsql-pitr-backup.log" base_backup_dir="/var/lib/pgsql/9.0/backups" wal_archive_dir="$base_backup_dir/wal_archives" pitr_archive_dir="$base_backup_dir/pitr_archives" timestamp=`date +%Y%m%d%H%M%S` backup_dir="$pitr_archive_dir/$timestamp" mkdir -p $backup_dir echo `date` >> $LOG /usr/bin/psql -U postgres -c "SELECT pg_start_backup('$backup_dir');" rsync -avW /var/lib/pgsql/9.0/data/ $backup_dir/ --exclude pg_xlog --exclude recovery.conf --exclude recovery.done --exclude pg_log /usr/bin/psql -U postgres -c "SELECT pg_stop_backup();"

  • Trouble typing accented letters at the terminal prompt after launching Python

    - by Nicojo
    Edit: Using Mac OSX 10.6, whether I use Terminal.app or iTerm.app, when I launch Python, I can no longer type accented letters (e.g.é or ä). Any ideas? ORIGINAL POST: I am using iTerm 0.10. I would like to type in a string with accented characters (e.g. é) but when I do so at the iTerm prompt, no character appears. This does not occur in Terminal. Could someone help me find out what the problem is, and eventually fix it? EDIT: In Terminal.app, I can use accented characters. However, when I launch the Python 2.71 prompt, I can no longer type in accented characters. When I quit python and return to the terminal prompt, I can again type accented characters. In iTerm, although I quit Python and restarted iTerm, I cannot type in accented characters (I do not know if I could before).

  • Windows media player 12 not launching from custom program

    - by Supertrolly
    There is a program we use for testing that calls windows media player and plays a media file. The problem is that windows media player fails to load unless you open and close it before starting the program. After that the program will open it every time without a hitch but after a reboot it is lost and you must do it again. My question is what could be voilate setting could windows media player have that would be lost on a reboot? I have tried programs like Regshot to capture changes to the registry that might be delated on reboot. The code for the program is very straight forward simply calling windows media player with a parameter with the media to play. Using process montior I have determined that is is crashing shortly after the program executes it. I am at a lost on this problem as I can not find what if anything it is changing to run windows media player.

  • Windows batch-file that continues after launching each program

    - by Sandy
    I'm trying to create a very simple Windows-XP batch file: Program1.exe Sleep 3 Program2.exe Sleep 5 Program3.exe Sleep 11 Of course, I don't want to have to exit each program, before the next 1 starts. The default for batch-files seems to be "stop until the previous program exists". How do I get this script to run as expected? Edit: The 3 executables listed above are more like "notepad" type programs. They open and run and don't just "open,run,close".

  • Can I disable the message line when launching ``screen -RR``

    - by Jimm Chen
    screen -RR is great. It does one of the two thing automatically: If there is any detached screen session, it picks up one can attach to it. If there is no detached screen session(no session yet, or all have been attach to other terminal), it creates a new screen session automatically. I use Windows server Remote Desktop a lot, screen -RR behaves almost the same when a client connects to a remote desktop server. It is natural and I like it. However, when screen -RR determines it should create a new session, it displays a message line at terminal bottom for 5 second. I'd like to suppress this message line because it brings us little benefit. In my opinion, a remote user can always easily distinguish whether he is connected to a resumed session(a piled-up display) or a newly created session(a clean display) from what he sees in the terminal window. So, is there a way to suppress the nag "New screen..." ? Just suppress that very one, not suppress message line globally. My env: opensuse 11.3, GNU screen 4.00.03 (FAU) 23-Oct-06

  • Launching multiple applications with a single command/script/shortcut

    - by Bill
    I realized a few days ago that every time I sit down at work, I do a few things after unlocking my computer. First, I open up Firefox, then I open up Chrome, then I log in to Digsby. I realized I could probably save repeating this daily by writing a small batch script to open up Firefox and Chrome , but I couldn't figure out how to make it work.. and since the whole effort is to save time I don't want to bash my head around in the windows command prompt to do it. I also tired this in powershell but ran in to a bunch of security nonsense. Is there a way to do this that I am missing? Bonus points if somebody has figured out how to manipulate Digsby via COM , scripting, or python =)
