I would always limit O - R for your view interfaces and packages.

It is normally a good idea to stick to Orthodox relational modeling when it comes to the design of the table.

Is that what you're looking for?

There must be a mistake somewhere as your type of appointment has no attributes of the applicant/person/sales_person (so there is no point in selecting them with the current definition).

Thanks for anyone who can help me. PS. Keep the answers in simple terms please.

    Hi BSRC$, in stock

    1. You have security software installed on the computer?
    2. You receive an error message when you restart the computer?

    Reinstalling Windows XP to the factory setting would not be the first option.

    It is possible that some third-party programs or the services installed on the computer interfere with the installation of service pack 3.

    I suggest that you try to uninstall service pack 3 from the computer by using the recovery console and subsequently ask the article below for what to do before installing the service pack 3on the computer.

  • I'm suddenly needing help with my browser Firefox (6.0.2)

    Hello
    I'm suddenly needing help with my browser Firefox (6.0.2)

    (OS: I use Windows XP).

    When I open the browser, I don't see is a totally white screen of white, with all the toolbars at the top.

    I know that my physical connections are very good: I have tested the modem, turned the pc market etc and I can also receive/send emails.

    This problem started today, September 8, 2011 and has never happened before.

    Is it a coincidence that Firefox itself to day before I disconnected yesterday evening? Could this be something to do with this particular new update?

    I also noticed that just before I "opened" Firefox, I now get a small box indicating:

    [JAVASCRIPT APPLICATION]
    Handl exc in Ev: TypeError: this oRoot.enable is not a function

    This never appeared before - I hope that it offers a clue has what is wrong.

    The browser not be stuck in Mode safe, said by the way.

    Of course, I can't find solutions to the problem on the internet, I don't physically see all Web sites!
    (A friend sends this request in my name from their pc)

    Any light you can throw on this problem of confusion would be much appreciated. I'd rather not have to uninstall and reinstall Firefox if possible.

    If the only option is to uninstall Firefox and reinstall from your site, I'm also in trouble (I can not see the internet or download).
    In this case, would you be able to send the .exe file as an attachment to my e-mail address? In the affirmative, please let me know and I'll give you more details.

    Thanks in advance.

    One possible cause is security software (firewall) that blocks or limits Firefox or plugin-container process without informing you, possibly after the detection of changes (update) for the Firefox program.

    Delete all rules for Firefox in the list of permissions in the firewall and leave your firewall again ask permission to get full unlimited access to the internet for Firefox and the plugin-container and the update process.

    See:

    Start Firefox in Firefox to solve the issues in Safe Mode to check if one of the extensions of the origin of the problem (switch to the DEFAULT theme: Firefox (Tools) > Add-ons > appearance/themes).

  • Need help with the port forwarding for a XBox remote Streaming

    I have a router R6200v2 and need help with port forwarding.

    I came across this set of instructions for setting up stream port forwarding XBox remotely from anywhere

    http://kinkeadtech.com/2015/07/how-to-stream-Xbox-one-to-Windows-10-from-anywhere-with-Internet/

    I have no idea when it comes to such things and I want to make sure I do it correctly without messing up my existing home network.

    Port Forwarding and triggering Port pages setup look very different from what the guy uses. Can someone walk me through what I do to set up please?

    Hi @varxtis,

    You must enter them in the field for a start external Port and external completion Port. You will need to send individually except for the range of 49000-65000. The steps are as follows.

    1. create a Service name (it could be something else that you cannot use the same service name twice. Ex. XBOX1, XBOX2 and so forth.)

    2. Select the type of service (TCP, UDP or both)

    3 entry 5050 times a start external Port and external endpoints.

    4. Select the IP address of your XBOX.

    5. Select apply.

    6 do the same for other port numbers. To the beach, use 49000 for the external departure Port and for the external completion Port 65000.

    Kind regards

    Need help with windows defender. all my files folders pictures everythiing disappeared and I find myself with this black screen and it is not all good: o)

    I don't know why vista windows no longer charge, or when the files and folders disappeared

    How Windows Defender is on this problem?

    Follow these steps to try to solve your problems of boot.

     

     

    Restore point:

    Try typing F8 at startup and in the list of Boot selections, select Mode safe using ARROW top to go there > and then press ENTER.

    Try a restore of the system once, to choose a Restore Point prior to your problem...

    Click Start > programs > Accessories > system tools > system restore > choose another time > next > etc.

    ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

     

    If restore work not and you do not have a Vista DVD from Microsoft, do a repair disc to do a Startup Repair:

    Download the ISO on the link provided and make a record of repair time it starts.

    Go to your Bios/Setup, or the Boot Menu at startup and change the Boot order to make the DVD/CD drive 1st in the boot order, then reboot with the disk in the drive.

    At the startup/power on you should see at the bottom of the screen either F2 or DELETE, go to Setup/Bios or F12 for the Boot Menu.

    When you have changed that, insert the Bootable disk you did in the drive and reboot.

    http://www.bleepingcomputer.com/tutorials/tutorial148.html

    Link above shows what the process looks like and a manual, it load the repair options.

    NeoSmart containing the content of the Windows Vista DVD 'Recovery Centre', as we refer to him. It cannot be used to install or reinstall Windows Vista, and is just a Windows PE interface to recovering your PC. Technically, we could re-create this installation with downloadable media media freely from Microsoft (namely the Microsoft WAIK, several gigabyte download); but it is pretty darn decent of Microsoft to present Windows users who might not be able to create such a thing on their own.

    Read all the info on the website on how to create and use:

    http://NeoSmart.net/blog/2008/Windows-Vista-recovery-disc-download/

    ISO Burner:http://www.snapfiles.com/get/active-isoburner.html

    It's a very good Vista startup repair disk.

    You can do a system restart tool, system, etc it restore.

    It is NOT a disc of resettlement.

    And the 32-bit is what normally comes on a computer, unless 64-bit.

    ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

    Data recovery:

    1. slave of your hard drive in another computer and read/save your data out there.

    2. put your Hard drive in a USB hard drive case, plug it into another computer and read/save from there.

    3 Alternatively, use Knoppix Live CD to recover data:

    http://www.Knopper.NET/Knoppix/index-en.html

    Download/save the file Knoppix Live CD ISO above.

    ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

    http://isorecorder.alexfeinman.com/isorecorder.htm

    Download the Vista software from the link above.

    After installing above ISO burning software, right click on the Knoppix ISO file > copy the Image to a CD.

    Knoppix is not installed on your PC; use only the resources of your PC, RAM, graphics etc.

    Change the boot order in YOUR computer/laptop to the CD/DVD Drive 1st in the boot order.

    Plug a Flash Drive/Memory Stick, BOOT with the Live CD, and you should be able to read the hard drive.

    When the desktop loads, you will see at least two drive hard icons on the desktop (one for your hard drive) and one for the USB key.

    Click on the icons of hard drive to open and to understand which drive is which.

    Click the icon for the USB drive and click on "Actions > Change the read/write mode" so you can write to disk (it is read-only by default for security reasons).

    Now to find the files you want to back up, just drag and drop them on the USB. When you're done, shut down the system and remove the USB key.

    See you soon.

  • Need help with the error of connection Internet "Reset local connection adapter".

    Original title: Need help with Internet connection.

    Hi, sometimes when I go to my office (HP 2009 m) I get a message that I am not connected to the internet (although I have no problem with the connection on my IPad).  When I click on solve internet connection Windows Network Diagnostics freezes when it gets to solve problems "the local connection adapter reset."   I have to turn off my computer by unplugging and then it works normally when she returns to the top. (Sorry if my explanation is difficult to decipher, I'm not very tech savvy) This could be the cause and how to fix it?  Thanks in advance.

    Well, I expected more of a response, but I'll wing it from here: your cable goes into a modem.  This modem can be a wireless modem/router, or simply a modem cable to your computer.

    Connection problem you might start by connecting the cable into the modem.  Ensure that it is well defined.  If everything looks good, then it is possible that there is a decline in cable service before he gets to the modem.  For example, the interface side of the House can be affected by a bad connection, for example water intrusion, or poor soil.  So you may want to check into that.  Then, there is always the possibility that your cable provider has lost his momentaily of transmission, and that the modem needs to be reset.  If this happens often, you must contact the cable provider.

    Modem, your computer can be connected by cable, so you will need to check how firmly the connection is.  Then, there is always the possibility that the modem is wrong.

    But if your connection is through a wireless modem/router, your connection may have lost because of a bad signal.  Once more..., the modem/router could go wrong.

    Edit has added:

    Looking back on what you said about the Ipad, I feel that you have a wireless modem/router.  It is possible that your connection to the desktop must be after you have used the Ipad.  For example, you may need to right-click on the monitor icon in the Systray to your desktop and open your network sharing Center.  Even if you can say that you are connected to the Internet, you may not.  Then... just ... simplement cliquer click on 'connect or disconnect', then find your network connection appropriate, right click on that and select disconnect, then immediately right-click the same but select Connect.


    Will be a new connection to the Internet.

  • Need help with the data storage store, local array and network connections

    Need help with my ESXi 4.1 installation

    My hardware:

    I built a server with an Asus P6T whitebox, i7 920, 12 Gig RAM, NIC, Intel Pro1000 PT Quad, 3ware 9650SE-12ML with 8 1.5 TB SATA green in a raid 6 array gives me about 8 + TB with a spare drive all housed within a NORCO RPC-4220 4U Rackmount Server chassis.  I also have a 500 GB SATA drive which will hold the ESXi and virtual machines.

    The network includes a firewall, Netgear Prosafe FVS336G, GS724Tv of Netgear ProSafe 24 port Gigabit Managed Switch on a dhcp cable modem internet service provider.

    I also have 2 old NetGear SC101T NAS disks (4to) I want to connect to the system how some - at a later date have... data on them and want to transfer to the new storage array. I always looking into the question of whether they will work with ESXi 4.1, or I might have to only access it through Windows XP.

    My Situation:

    I have already installed ESXi 4.1 and vsphere client with no problems and it is connected to a dhcp cable internet service.  I've set up host via a dynamic DNS service name give me a static hostname on the internet.  I installed three machines to virtual OS successfully at the moment and now want to first start by creating a multimedia storage server which will use some of this new 8 TB array, then separate data storage for use with a web server small overhead storage and a backup.  It is a domestic installation.

    Help with the data store and network:

    I was doing some reading, because I'm new to this, and it looks like I'll probably want to set up my table via ESXi as a nfs disk format.  Now, the data store is usually in another physical box from what I understand, but I put my readers and ESXi all in the same box.  I'm not sure that the best way to put in place with grouped network cards, but I want to make this work.

    I understand that in ESXi 4.1 using iSCSi LUN must be less than 2 TB, but nfs - I should be able to add a bigger partition then 2 TB (for my multimedia) in nfs, right? or should I still add it separately as a separate 2 TB drives and then extend them to get the biggest space.

    Any suggestions or direct resources showing examples on how to actually add some parts of the table as data warehouses separate nfs.  I know that to go to the configuration tab, and then select Add to storage, and then select nfs. I have not my picture, but it's here that I don't know what to do because ESXi 4.1 system already has an address, should I put the same thing to the new data store array also (will it work?), and what should I use for the name of the folder and the store of data... just do something to the top.  I thought to later install Openfiler (for a multimedia storage using this table server) as a virtual machine, use the table with esxi so that I can access the same storage space with widows and linux-based systems.

    I also know I have to find a way to better use my quad nic card... put in place of virtual switches, grouping, etc HELP?

    Any direction, assistance, similar facilities to sample, suggestions or resources that would help would be great. I did a lot of hunting, but still a little confused on how to best to put in place.

    You must think of VMDK files of large databases with records of random size guest go read some data (a DLL or an INI file), maybe write some data back, then go read other data. Some files are tiny, but certain DLLs are several megabytes. It's random i/o all and heavy on the search time. IO Opsys is small random operations that are often sequential (go read data, write data, go read other data,...) so that deadlines are critical to the overall performance. That's why people say OPS are / s of reference and forget the MBs flow. The only time where you bulk transfers are when you read media (ISO files).

    Well, now forget all this. Actually the disk activity will depend on the specific applications (database? mail server? machines compiler?), but the above is true for boots, and whenever applications are idle. You should see the profile to know.

    RAID 10 is faster (and often more reliable) than RAID 5 or RAID-6 except in certain specific cases. In General RAID 10 is ideal for many random writes, since the calculation of parity for RAID-5 and - 6 adds to the overall latency between command and response - latency is cumulative if a little slow here and a little slow it adds up to a lot of overall slow synchronous especially with e/s on a network. OTOH RAID-5 and -6 can produce faster readings due to the number of heads, so you can use it for virtual machines that transfer bulk. Test. You may find that you need several different types subdashboards for best results.

    You said 3ware, they have some good grades on their site, but don't believe it. With my 9650 that I found myself with only a couple of their recommendations-, I put the (simple) table for allocation size 256 k, nr_requests at 2 x the queue_depth and use the planner date limit. I had the habit for the Ext4 file system formatted with stride and stripe-width synced to the table and used the options large_files with fewer inodes (do not use the huge_files option unless you plan to have single VMDK files in the terabyte range). Use a cache of great reading in advance.

    Virtual machines use VMDK files in all cases except raw iSCSI LUN that they treat native disks. VMDK is easier to manage - you can make a backup by copying the file, you can move it to a PC and load it into another flavour of VMware, etc. There could be some features iSCSI to your San as a transparent migration but nothing for me. NFS has less chatter of Protocol if latency lower times to complete an operation. NFS is good to read and write a block of data, that's all it boils down to.

    UPS is good, but it won't help if something inside the machine explodes (UPS does nothing if the PC power supply goes down). If the RAID card has an option for a battery backup module, so it can contain some writings in memory and may end up the disk i/o after replacing the power supply. 3ware also limits the types of caching available if help is not installed, and you get just the right numbers with the module.

  • Newbie needs help with cookie cutter in PSE8

    I'm new to PSE8, the cookie cutter tool and work with layers, what I need help with to accomplish what I want to do.

    I want to use one form of cookie cutter to make several 'holes' in an image, leaving a solid color background layer to show through. (Or another path, use the form of Cutter of biscuit as a solid 'rubber stamp' color to stop shape on the image in several places)?

    I opened my image in the editor and create a solid color fill layer, and then I select the shape of Cutter of biscuit that I want to use, for example a sheet.  Then I select the color fill layer, click and drag to create the sheet randomly somewhere in it.  When I release the mouse button, the window returns to the image and there is the leaf, locked in a box, in the color I want, on the image. I drag the box (leaves) to where I want it and click the green checkmark to accept. So far so good.  Here's the problem: in order to create another sheet on the image, I have to create another layer of fill and repeat the whole process.  If I try to use the same fill layer to a second sheet, the first sheet disappears.  I must be missing something very simple, but I can't figure out how to get out several sheets of a filling layer.  Also, I use a version without the constraint of the sheet because I would create several sheets of different sizes out of the fill layer as well.

    I would be grateful for any help or suggestion!

    Try the following:

    1. File > new > empty file - white
    2. Create a new layer, fill it red
    3. Create a new layer, fill it out of blue
    4. Access the marquee tool, drag the rectangle to the blue layer. You should see "ants in market". Press DELETE on the keyboard.  You should see red in the rectangular hole.
    5. Access to the custom shape (U) tool. In the form of culture library, select the heart shape black all and hang out on the blue layer. Press CTRL + left click the thumbnail of the layer of the capping layer for "mobile dotted." Hit delete on keyboard twice, and you should see red in the heart shaped hole.
    6. Continue with other forms.

    Need help with the installation of an adapter of graphics Super Palit GeForce 9500GT - 512 MB - DDR2 SDRAM in a M2N68 motherboard (narra6). Should I disable the onboard graphics in the bios? When the card is installed, no VGA work outs and the PC does not start. Checked and recontroler implementation of the card in the PCI slot. PC is a desktop HP G5200uk PC. Windows 7 operating system.

    Hello

    The link below is a guige to install a video card in your Pc.  In particular, it seems that you will have to perhaps specify the location of the new card in the bios and save this change before you install the new card - see step 4 in the guide on the link below.  If your new card fits into the PCI Express x 16 slot, you will need to define PCI Express in the bios and save the changes.

  • I need help with an installation failure to interpret and troubleshoot a Setup log.

    Background: A few years ago, many editors of cinema used Final Cut Pro 6 (also contained in Final Cut Studio 2) for their editing projects.  Shared Apple Final Cut X uses a different format that is not compatible with FCP6.  Sometimes, these editors are called to work on a few historical projects that have been published in FCP6 and need this version to run now.

    Starting with OS X Lion, FCP6 would install not in Lion and thereafter.

    According research by Jeremy Johnston as noted on his blog, he discovered that Apple has inserted a file in the folder CoreServices in the Library folder of the system folder that causes versions the version Final Cut Pro X (and other older Apple programs in the same situation) do not settle.  He suggested changes to this file that would seek to prevent interfering with the installation of FCP6 in Lion, many users of final cut PRO 6 were successful in their efforts to install in Lion and work with it.

    Later in a discussion update on installing FCP6 in Mavericks, HawaiianHippie determined that the simplest way to perform the installation of FCP6 was simply copy this file and remove it from the system folder, install FCP6 and then restore the copied file:

    I used this method with success to install FCS2 in Yosemite:

    [click on images to enlarge]

    However, in my attempts to install FCS2 in El Capitan, it fails in the last 5% to install the first DVD:

    First of all, I need advice on how to display an extremely large Setup log in this thread (on MacRumors, it is a method to insert a 'code' in a small box that can be the object of a scrollbar if necessary to read all along).  I am unable to find such a method to post here.

    Then once approved, I need help to determine which component is causing the installation to fail and perhaps this element can be omitted from the installation:

    If this element is not required, then maybe FCP6 can be installed successfully without it.  And if that omitted element is necessary, perhaps a manual method to install it can be determined by pacifists.

    It is my goal to help those who need to install and use FCP6 on their new Macs running El Capitan.

    Here is the post on MacRumors with pre-installed Setup log:

  • Need help with network home using Airport extreme

    I need help with my home network.  I'm not very aware when it comes to all things network.  Here's how my network is currently set up.

    Cable modem to Airport Extreme for Gigabit Switch.  Cables come out of the switch to all areas of the House.  I have 2 other extreme airport connected in other rooms of the House directly on the wall that dates back to the switch.  I hope I am explaining that properly.

    My problem is that this seems to have caused some of my connections cable does not work.  When everything is configured, it has worked well.  All connections in the House worked.  Then we have disconnected one of the extreme airport and moved to another location in the House to have the best wifi coverage.  Since that time, a lot of the ethernet wall plugs are not working.  For example, when I plug in my Macbook Pro in making ethernet in my kitchen, it says connected but it has an assigned ip address and cannot connect to the internet.

    Any help you can provide would be great.

    I would like to get the return tech to help you to...

    But it is likely that something (or someone) has tampered with the settings.

    The layout is fine... but you can cause problems with the network by creating a loop.

    This can happen because the AE you moved is connected wrongly... somewhere in the network it is connected to the switch again.

    Or AE is set to expand wireless... It's FAKE... It will loop the network on the back main EI wireless.

    Unplug the two AE you have that function as extensions...

    Turning off everything else... then it works again...

    Do it in this order.

    Modem... Wait 2 min

    AE... Wait 2 min

    Switch.

    Now check that the network is working properly... power of customers in various locations and make sure everything is good.

    If so, then manually reset the two AE of factory and redo their installation.
