  • iPhone: Save boolean into Core Data

    - by Nic Hubbard
    I have set up one of my core data attributes as a Boolean. Now, I need to set it, but XCode keeps telling me that it may not respond to setUseGPS. [ride setUseGPS: useGPS.on]; What is the method for setting a boolean in core data? All my other attributes are set this way, and they work great. So, not sure why a boolean does not work to be set this way?

  • Problems using xcode in debug mode with Core Plot

    - by Splash6
    I'm having a problem compiling an application which uses Core-Plot in debug mode. It works absolutely fine compiling in release mode, but when I compile in debug mode I get an error that the header file for Core-Plot can't be found. Any idea which of the many settings in x-cide might be causing this problem?

  • Can SQL Server Compact be used as both a Source and Destination in SSIS?

    - by Rich
    I'm wondering if SQL Server Compact Edition can be used as both a Source and Destination in an SSIS dataflow. I know I can setup a SQLMOBILE connection manager, and I've found some information that mentions using it as a Destination, but nothing on using it as a Source. What I'm looking to do is to transfer data from one SQL Server Compact file to another.

  • Backing up my data causes my server to crash using Symantec Backup Exec 12, or How I Came to Loathe

    - by Kyle Noland
    I have a Dell PowerEdge 2850 running Windows Server 2003. It is the primary file server for one of my clients. I have another server also running Windows Server 2003 that acts as the core media server for Symantec Backup Exec 12. I recently upgraded from Backup Exec 11d to 12. This upgrade was necessary because we also just upgraded from Exchange 2003 to Exchange 2007. After the upgrade I had to push-install the new version 12 Backup Exec Remote Agents to each of the servers I am backing up (about 6 total). 5 of my servers are doing just fine, faithfully completing backups every night. My file server routinely crashes. Observations: When the server crashes, it does not blue screen, it just locks up completely. Even the mouse is unresponsive. If you leave the server locked up long enough, it will eventually reboot itself and hang on the Windows splash screen. There is absolutely zero useful Event Viewer evidence of a problem. The logs go from routine logging to an Unexplained Shutdown Event the next morning when I have to hard reset the server to get it to boot. 90% of the time the server does not boot cleanly, it hangs on the Windows splash screen. I don't have any light to shed here. When the server hangs all I can do is hard reset it and try again. Even after a successful boot and chkdsk /r operation, if you reboot the machine, you have a 90% chance it won't back up again cleanly. The back story: This server started crashing during nightly backups about a month ago. I tried everything I could think of to troubleshoot the problem and eventually had to give up because I could not keep coming to the office at 4 AM to try to get the server back online. One Friday I got lucky and the server stayed up for its entire full backup. I took this opportunity to restore the full backup to a temporary server I set up and switched all my users to the temporary. Then I reloaded the ailing file server. I kept all my users on the temporary file server for about 3 weeks. I installed the same Backup Exec Remote Agent and Trend Micro A/V client on the temporary server that I was using on the regular file server. During this time, I had absolutely no problems backing up the temporary server. I tested the reloaded file server extensively. I rebooted the server once an hour every day for 3 weeks trying to make it fail. It never did. I felt confident that the reload was the answer to my problems. I moved all of the data from the temporary server back to the regular server. I got 3 nightly backups out of it before it locked up again and started the familiar failure to boot cleanly behavior. This weekend I decided to monitor the file server through the entire backup job. I RDPd into the file server and also into the server running Backup Exec. On the file server I opened the Task Manager so I could view the processes and watch CPU and memory usage. Everything was running smoothly for about 60GB worth of backup. Then I noticed that the byte count of the backup job in Backup Exec had stopped progressing. I looked back over at my RDP session into the file server, and I was getting real time updates about CPU and memory usage still - both nearly 0%, which is unusual. Backups usually hover around 40% usage for the duration of the backup job. Let me reiterate this point: The screen was refreshing and I was getting real time Task Manager updates - until I clicked on the Start menu. The screen went black and the server locked up. In truth, I think the server had already locked up, the video card just hadn't figured it out yet. I went back into my bag of trick: driving to the office and hard reseting the server over and over again when it hangs up at the Windows splash screen. I did this for 2 hours without getting a successful boot. I started panicking because I did not have a decent backup to use to get everything back onto the working temporary file server. Once I exhausted everything I knew to do, I took a deep breath, booted to the Windows Server 2003 CD and performed a repair installation of Windows. The server came back up fine, with all of my data intact. I can now reboot the server at will and it will come back up cleanly. The problem is that I'm afraid as soon as I try to back that data up again I will back at square one. So let me sum things up: Here is what I've done so far to troubleshoot this server: Deleted and recreated the RAID 5 sets. Initialized the drives. Reloaded the server with a fresh Server 2003 install. Confirmed with Dell that I have installed the latest, Dell approved BIOS and NIC drivers. Uninstalled / reinstalled the Backup Exec Remote Agent. Uninstalled the Trend Micro A/V client. Configured the server not to reboot itself after a blue screen so I can see any stop error. I used to think the server was blue screening, but since I enabled this setting I now know that the server just completely locks up. Run chkdsk /r from the Windows Recovery Console. Several errors were found and corrected, but did not help my problem. Help confirm or deny the following assumptions: There are two problems at work here. Why the server is locking up in the first place, and why the server won't boot cleanly after a lockup. This is ultimately a software problem. The server works fine and can be rebooted cleanly all day long - until the first lockup - following a fresh OS load or even a Repair installation. This is not a problem with Backup Exec in general. All of my other servers back up just fine. For the record, all of the other servers run Server 2003, and some of them house more data than the file server in question here. Any help is appreciated. The irony is almost too much to bear. Backing up my data is what is jeopardizing it.

  • Setup Remote Access in Windows Home Server

    - by Mysticgeek
    One of the many awesome features of Windows Home Server, is the ability to access your server and other computers on your network remotely. Today we show you the steps to enable Remote Access to your home server from anywhere you have an Internet connection. Remote Access in Windows Home Server has a lot of great features like uploading and downloading files from shared folders, accessing files from machines on your network, and controling machines remotely (on supported OS versions). Here we take a look at the basics of setting it up, choosing a domain name, and verifying you can connect remotely. Setup Remote Access in Windows Home Server Open the Windows Home Server Console and click on Settings. Next select Remote Access, it is off by default, just click the button to turn it on. Wait while your router is configured for remote access, when it’s complete click Next. Notice that it will enable UPnP, if you don’t wish to have that enabled, you can manually forward the correct ports. If you have any problems with the router being automatically configured, we’ll be taking a look at a more detailed troubleshooting guide in the future. The router is successfully configured, and we can continue to the next process of configuring our domain name. The Domain Name Setup Wizard will start. Notice you will need a Windows Live ID to set it up –which is typically your hotmail address. If you don’t already have one, you can get one here. Type in your Live ID email address and password and click Next… Agree to the Home Server Privacy Statement and the Live Custom Domains Addendum. If you’re concerned about privacy and want to learn more about the domain addendum, make sure to read about it before agreeing. There is nothing abnormal to point out about either statement, but if this is your first time setting it up, it’s good to review the information.   Now choose a name for the domain. You should select something that is easy to remember and identifies your home server. The name can contain up to 63 characters, numbers, letters, and hyphens…and must begin and end with a letter or number. When you have the name figured out click the Confirm button. Note: You can only register one domain name per Live ID. If the name isn’t already taken, you’ll get a confirmation message indicating it’s god to go. The wizard is complete and you can now access the home server from the URL provided. A few other things to point out after you’ve set it up…under Domain Name click on the Details button… Which pulls up the domain detail information and you can refresh the data to verify everything is working correctly. Or you can click the Configure button and then change or release your current domain name. Under Web site settings, you can change you site page headline to whatever you want it to be. Accessing Home Server Remotely After you’ve gotten everything setup for your home server domain, you can begin to access it when you’re away from home. Simply type in the domain address you created in the previous steps. The start page is rather boring…and to start accessing your data, click the Log On button in the upper right hand corner. Then enter in your home server credentials to gain access to your files, folders, and network computers. You won’t be able to log in with your administrator user account however, to protect security of your network. Once you’re logged in, you’ll be able to access different parts of your home server shares and network computers. Conclusion Now that you have Remote Access setup, you should be able to access and manage your files easily. Being able to access data from your home server remotely is great when you need to get certain files while on the road. The web UI is pretty self explanatory, works best in IE as ActiveX is required, and is smooth and easy to work with. In future articles we’ll be covering a lot more regarding remote access, including more of the available features, troubleshooting connection issues, and enabling access for other users.

  • Is the Core i5 Processor from Intel like the Celerons of yesteryear?

    - by Chris
    The title pretty much says it. I know that the Core i7's are Quad Core and Hyper-threaded (so 4 cores, and 8 logical), and the Core i5's are Quad Core as well but not Hyper-threaded, does this really make a difference? Or are the only people who are going to care are the ones who CPU intensive operations? I'm a developer, so I'm more concerned about hard drive speed most times than CPU speed. Any thoughts?

  • SQL Server backup

    I have Full-Backup-A Transaction-Log-Backup-A Transaction-Log-Backup-B (*) - I have to restore this point Full-Backup-B How to do it? It seems that the only way is Full-Backup-A Transaction-Log-Backup-A Transaction-Log-Backup-B Shut-off client access Transaction-Log-C Full-Backup-B Allow client access Are there any other ways to guarantee that nothing did happen with the database between last transaction log and the next full backup. I was thinking about a. Starting transaction log backup simultaneously with full backup. b. Using differential back up while clients are connected and making full backup during maintenance window only c. Run replication and back-up the replica, stopping and restoring duplication services in points 4 and 7 and feel that it is actually hopeless.
