  • powerbuilder: insert data using datawindow

    - by Archangel
    Hi, suppose I have a table called 'test', into which there are three columns named test_id, test_name and test_age. I have used a retrieval argument called :al_test_id to promot the user to insert an id and search the database for the corresponding id entries, and if found, display it to the user. Now if no entry is found, then I want the user to be able to insert a new row using the id that he/she entered as the retrieval argument. How can I do that?

  • Spotlight can't see anything in Applications

    - by mix
    There have been other threads on this but none of the solutions mentioned have helped me. Spotlight has stopped showing any results for my Applications. I've tried reindexing and removing the index so it rebuilds it. No change. I've tried adding Applications to the Privacy tab and removing it, no change. I tried repairing disk permissions and redoing the above, no change. I've tried removing everything from the index except Applications and then I just get nothing for any search at all (except dictionary entries). I tried adding a symlink in my homedir to Applications and reindexing, but no change. Any ideas on what to do? I'm running Snow Leopard. This is driving me crazy! Update: I've noticed that when I start a reindex with sudo mdutil -E / and then immediately do a spotlight search for an app that the app shows up temporarily until spotlight gets disabled due to active indexing. After the indexing is done the app entries go away.

  • Help Installing SQL Server 2008 Express Edition

    - by Jordan S
    Ok I am running Windows 7, 64 bit. I cleaned of SQL server 2005 completely off my system leaving only SQL Compact Edition. I went here http://www.microsoft.com/downloads/details.aspx?FamilyID=01af61e6-2f63-4291-bcad-fd500f6027ff&displaylang=en and installed SQL Server 2008 Express Edition Service Pack 1. After the install, under my start bar menu all i have for SQL configuration tools are the Configuration Manager, Error and Usage Reporting and the Install Center. I don't have the SQL Managment Studio. So I went here http://www.microsoft.com/downloads/details.aspx?FamilyID=08e52ac2-1d62-45f6-9a4a-4b76a8564a2b&displaylang=en and downloaded the SQL Server 2008 Management Studio Express but when I try to install it I get a warning says This program has known compatibility issues and that I need to Install SQL Server 2008 Service Pack 1. I thought that is what I installed. So, I tried to continue running the install but I then get an error message that says Invoke or BeginInvoke can not be called on a Form before it is opened... How can I check if Service pack 1 is installed or not? What should I do? Also I rebooted my system and checked for Windows Updates and it says that Windows it up to date.

  • Music player alternative to windows Media Player

    - by patjbs
    I find the UI and general usability of the prepackaged windows Media Player to be cludgy and at times incomprehensible. I used to use programs like WinAmp and Sonique, many years ago. What are some current alternatives to the windows Media Player? I don't have iTunes - I'm pretty happy with ripping my own audio files from my album collection. I'm specifically looking for the follow qualities/abilities: Easy sorting and manipulation of the media library Easy tagging of media - marking favorites and ratings, etc. Preferably lightweight. Something like a Picasa for audio media.

  • OSX: Mimic Ubuntu IP Masquerading via iptables with ipfw

    - by Dogbert
    Good day, I am attempting to replicate a setup I have between a router and an Ubuntu PC, and have the same setup working on my MacBook (10.6, Snow Leopard). First, I have a router that has a USB port. When I plug it into my Ubuntu PC, it creates an RNDIS connection, allowing me to connect to the router over the USB cable via an IP connection. When I plug it into my computer via USB, it gets assigned an IP address of 172.16.84.1, and a new adapter appears when I type ifconfig. I can then SSH into the device via ssh [email protected]. When I log in to the device, I flush the routes, then create the default route: admin@localhost> route -f admin@localhost> route add default 172.16.84.2 Now, in my Ubuntu machine, I use iptables to enable IP masquerading: root@Valhalla> sudo iptables -t nat -A POSTROUTING -s 172.16.84.2 -j MASQUERADE Once this is all done, the router has internet access over the USB connection to my PC. I am trying to replicate this exact setup on my MacBook now (Snow Leopard), but iptables does not exist for OSX, not even a Macports version exists. I have scoured through other questions on StackOverflow that cover the usage of the ipfw command, which apparently works as a drop-in replacement for iptables. However, the syntax is significantly different, and I'm pretty much lost. Does anyone with some experience with ipfw have some suggestions on how I could accomplish this and create a NAT connection via IP masquerading like I could with my Ubuntu PC? Thank you for your assistance.

  • How do I troubleshoot a slow hard drive?

    - by Bruce Connor
    My computer is suffering of slow-downs and I'm not surprised (it's around 6 years old). Here's what I've verified: They are not very frequent (only a couple of times a day). When they happen a single application will hang for 10-60 seconds, while the rest don't hang but also get slow. Even as it is happening, the CPU usage stays low. It happens to applications (such as text editor, firefox, skype). It never happens to some applications (such as games) which I use for hours under heavy CPU load. Also of note: The Graphics card and PSU are new (around a year). Though I have a decent amount of software installed right now, this was happening even right after I reinstalled Windows. This HDD has been through many partinioning schemes, and a few heavy operations (such as moving around 200GB of data). Because of the above, I am already 70% sure the problem is with the hard drive. Before I replace it, however, I want to rule out other less likely possibilities (such as RAM, software, or PSU). I don't have the money to replace the entire box right now, but I can easily replace one of the components. I've read several questions (such as this one) which give general guidance on troubleshooting an unknown issue, that is not what I'm looking for here. My main question is: What tests or benchmarks can I run to verify I have a problematic hard drive? I don't need to solve this problem, I am content with just making sure it's the hard drive. I could borrow a newer hard drive from a friend and see if it gets better. A positive result would rule out all other components, but it wouldn't rule out a software issue (since this new hard drive won't have any of the software I use daily). Running on Windows/Linux.

  • Safe mode boot with no change on screen but ongoing hard disk activity - why?

    - by omatai
    I have a machine with a dying hard drive - bad sectors are starting to multiply :-( The first sign (24 hours ago) was that it had an unmountable boot volume. At this time, I tried booting to safe mode with command prompt, which worked, after which I rebooted normally and ran a chkdsk. It has since been working as well as I could expect, but slowly getting less reliable. So I scheduled another chkdsk on both partitions (C: - boot, D: - data), having freed up a lot of space on both partitions to give Windows a little more scope for repairs (hopefully?). I then rebooted. On reboot, it protested about the unmountable boot volume again, so I booted to safe mode. I got the same list of drivers loaded as yesterday, and then no change to the screen for the past 2 hours. However, I see a flickering hard drive indicator light - not always on, but seldom ever off. What is happening? Is the chkdsk that runs in safe mode one which produces nothing on the screen and so chkdsk could be doing its thing... or is Windows still trying (but failing) to boot into Safe Mode?

  • Hints on diagnosing performance issue in OpenBSD firewall

    - by Tom
    My OpenBSD 4.6 pf firewall has started having really bad performance in the past few weeks. I've isolated the firewall (as opposed to the WAN connection, switch, cable, etc.) as the problem, but need a hint on how to further diagnose or fix the problem. The facts: Normal setup is: DSL Modem - FW Ext. NIC - FW Int. NIC - Switch - Laptop Normal setup described above gives only 25 Kbps! Plugging the laptop straight from the DSL modem gives a 1 MBps connection (full speed, as advertised). Therefore, the DSL connection seems to be OK. Plugging the laptop directly into the firewall's internal NIC (bypassing the switch) also gives only 25 Kbps. Therefore, the switch does not seem to be a problem. I've replaced the ethernet cables, but it didn't help. Here's the weird thing. Reloading the ruleset (/sbin/pfctl -Fa -f /etc/pf.conf) causes the laptop's connection to go up to 1 Mbps (i.e. full speed) for a few minutes before it gradually degrades back down to 25Kbps again. Any ideas on what's wrong or how I could further diagnose the problem?

  • Implication of variable context switching time

    - by Rob
    Hi, I know that constant switching time of the Linux scheduler was a big achievement. I was just asking myself the question what would be the implication of a non-constant switching time. The only obvious reason I can think of is real-time systems where we have to meet deadlines. There it is obviously no ideal if the switching time is "random". Are there any other good reasons that favour constant switching times? Many thanks, Rob

    - by Anriëtte Combrink
    Hi there We have a Mac OS X Server setup to be a VPN as well, we also have a freelancer who wants log in to the Mac OS X VPN on our server, but he keeps getting errors. I have tested the VPN with our Macs, and they connect fine using Snow Leopard. Our VPN type is L2TP over IPSec and we use a shared secret instead of a certificate. Does anyone have any pointers for me?

  • Shut Down took way too long because of "Background Programs"

    - by Christopher Chipps
    I tried shutting my desktop PC (with Windows7) down but after several attempts (like 4 or 5) at Start -- Shut Down, the GUI was still there and it was not shutting down. I didn't think there were any programs running when I pressed Shut Down, so I went into the taskbar (Ctrl + Alt + Del) to check out the processes. Once I did that, a screen appeared with a message stating that there are "background programs" still running and it gave me an option to "Force Shut Down" which I pressed and it shut down normally. Does anyone know why this would happen?

  • Project management, timesheet and planning software

    - by hfidgen
    Hiya, I'm trying to find an integrated PM solution which will give my business all of the following: Timesheeting so we can track time spent on tasks Holiday planner (integrated with timesheet and project management Project management tool, integrating the above, with milestones, gantt chart, dependancies etc. Forecasting ability (nice to have, but not a requirement) Reporting capability - especially time spent on projects, costs etc. Now yeah, that's quite a lot of functionality, I appreciate that! But currently we've got 3 systems, none of which really talk to each other and it's a right headache. So far we've looked at: OpenWorkbench - not enough features Basecamp - not enough features and too reliant on online MS Project - too expensive? Can anyone throw some other hats into the ring which maybe I've not heard about? Really interested to hear how other people have approached this, it's not an unusual business requirement! Thanks!

  • How can I get my routers to forward ports correctly?

    - by Giffyguy
    My network currently looks like this (simplified): Note that Router #2 is connected to the LAN interface of Router #1. This should be familiar to anyone who has seen a standard static-IP setup with an additional firewall for a residence or other small building. Router #1 is actually my cable gateway, but since it is a fully functional router/firewall, I am going to refer to it as a router. Now, I need to open various ports in both firewalls for incoming communication to my server - port 80 is a good example. So I've opened up port 80 in Router #2, and so far all incoming traffic at the public IP X.X.X.129 is being routed correctly. The problem is that I also need my server to respond to incoming traffic at the public IP X.X.X.130 on the WAN interface of Router #1. Naturally, I can't just tell Router #1 to forward port 80 to another public IP. Port forwarding is only supported when the traffic is being directed to the LAN subnet. I am willing to restructure my network topology if required, with the following conditions: Router #1 cannot have its WAN IP reassigned - X.X.X.130 is mandatory. Router #1 cannot be moved or disconnected from the cloud. The server cannot be given a second IP address. I would prefer the server to have a private IP address - e.g. 10.0.0.10 I'd like to keep Router #2, but it can have a private IP - e.g. 10.0.1.10 Following these rules, I need to get my server to receive incoming traffic on port 80 from both public IP addresses. Does anyone on SU know if this is possible? So far my only theories have been to set up a static route on either router, or to somehow combine my two subnets into a single subnet.

  • OS X Headphone jack issue [closed]

    - by Alex Coady
    Possible Duplicate: Optical Audio out stuck on on a MacBook When I plug my headphones into my iMac (27-inch, Mid 2011; OSX 10.8.1) and try to adjust the volume, the volume popup shows a greyed out speaker and there's a circle with a line through it signalling that it isn't working. I've tried the headphones with my iPhone, other iMacs etc and they're fine. This is incredibly frustrating. Other headphones don't generally work either. In Sound preferences the headphones are being listed as "Optical digital-out port" which is incorrect and would explain the problem, but doesn't help me fix it. Any ideas?

  • Secondary drive corrupted/not reading

    - by Sebastian
    When I connect my Seagate Barracuda to the computer, it shows up on the list of drives in Windows Explorer, but right clicking on it crashes Windows Explorer, opening it won't do anything, and I cannot start disk manager when it is connected. Trying to search the drive also freezes Windows Explorer. I have tried to run CHKDSK on it, and it was "unable to read $J data stream" for the Usn Journal. Also, it was an internal drive, but I pulled it out and hooked it up externally so I could test if it was that drive causing the problems. Is there any way for me to copy the files off of the drive?

  • What ssh command would I use to set up "backwards listening"

    - by Nathan
    Machine A is behind a firewall. I have physical access to it, but I want to log into it remotely, and I do not have access to the firewall settings. Machine B is remote, and not behind any firewall. (It's my linode) Machine C is the mobile device I'm going to attempt to ssh into A from. Is there an ssh command that I can run from machine A that connects to machine B and stays open, that will allow me to log into A from C, via B? From the manual I'd guess it would be to run the follwing on A ssh -R *:9999:localhost:22 me@B and then run this on C ssh me@B -p 9999 but the previous command reports "Connection refused."

  • Terminal OS X Error when using Python

    - by Stephen
    Hey, I'm trying to learn how to program so I've installed the latest version of Python and I've been following the Byte of Python tutorial. I'm using Textwrangler I've only gotten as far as the simple "Hello World" intro and I'm already having a problem. I type out the code (just without the ""): "#!/usr/bin/python" "#Filename: helloworld.py" "print('Hello World')" and save it to my desktop as helloworld.py. I then go into terminal and type "python3 helloworld.py" and I get the following error message: /Library/Frameworks/Python.framework/Versions/3.1/Resources/Python.app/Contents/MacOS/Python: can't open file 'helloworld.py': [Errno 2] No such file or directory I was hoping someone could tell me what I'm doing wrong. If I choose to run the script from Textwrangler it operates just fine however I'm not able to access it from the Terminal. Thanks so much!

  • Expanding Files 0%, error 0x80070017 Windows 7 x64 RTM

    - by Liam
    I have downloaded Windows 7 x64 from MSDN. I have checked the hash of the file and it is correct. I have them made a bootble USB stick (http://kmwoley.com/blog/?p=345 (had to use my vista bootsect.exe as running 32bit at the moment). When I boot from the USB it fails when expanding the file. It stays on 0% and fails after around 90 seconds. The error is 0x80070017. As the hash is correct and I am using USB I guess it could be a hardware problems. Any advice how to get Windows 7 installed? The machine is a Dell Studio Slim.
