How to guarantee a box has at least one active record
Hello
I have a table block (two-elements of text with a box,
I want to prevent the user from leaving the form unless there is at least one active record?
in the item properties box
When checked the value property value = 1
value when the value of uncontrolled property = 0-> this unchecked value must be 0. If you can find out if the box is checked or unchecked at least
then add article no db to the block. Use the text-to-speech function SUM this out of the box.
If at least one checkbox is selected, this summary will be > 0
If all elements of the block check box is not checked, this article summary = 0
maybe help you.

I think my computer is "hidden." There are Web sites that I have not visited at all, including the Mozilla developers, who appear as previously visited. In addition, whenever I load a page, it seems to load twice, as if another copy is running in the background. Help, please.
The Firefox sync system don't live synchronization of all of the Web site that you visit on another device. That means, the problem with your sites Web appearing to load twice is more than likely not caused by the synchronization system.
For added security, please change the password for your Firefox sync account to make sure that nobody can access it.
It seems to me that you have an infection on your computer. You can try these free programs to search for malicious software that work with your existing anti-virus software:

- Anti-Rootkit utility - TDSSKiller
- AdwCleaner (for more information, see this other AdwCleaner download page)
- Hitman Pro
- ESET Online Scanner
Microsoft Security Essentials is a good permanent antivirus for Windows 7/Vista/XP, if you do not already have one. Windows 8 already has integrated antivirus.
Please let me know if the scans detect something.

Vista and Windows 7 updated drivers love then here's how update the most important.
This is my generic how updates of appropriate driver:
This utility, it is easy see which versions are loaded:
-Free - DriverView utility displays the list of all device drivers currently loaded on your system.
For each driver in the list, additional useful information is displayed: load address of the driver,
Description, version, product name, company that created the driver and more.
http://www.NirSoft.NET/utils/DriverView.htmlFor drivers, visit manufacturer of emergency system and of the manufacturer of the device that are the most common.
Control Panel - device - Graphics Manager - note the brand and complete model
your video card - double - tab of the driver - write version information. Now, click on update
Driver (this can do nothing as MS is far behind the certification of drivers) - then right-click.
Uninstall - REBOOT it will refresh the driver stack.Repeat this for network - card (NIC), Wifi network, sound, mouse, and keyboard if 3rd party
with their own software and drivers and all other main drivers that you have.Now in the system manufacturer (Dell, HP, Toshiba as examples) site (in a restaurant), peripheral
Site of the manufacturer (Realtek, Intel, Nvidia, ATI, for example) and get their latest versions. (Look for
BIOS, Chipset and software updates on the site of the manufacturer of the system here.)Download - SAVE - go to where you put them - right click - RUN AD ADMIN - REBOOT after
each installation.Always check in the Device Manager - drivers tab to be sure the version you actually install
presents itself. This is because some restore drivers before the most recent is installed (sound card drivers
in particular that) so to install a driver - reboot - check that it is installed and repeat as
necessary.Repeat to the manufacturers - BTW in the DO NOT RUN THEIR SCANNER device - check
manually by model.Look at the sites of the manufacturer for drivers - and the manufacturer of the device manually.

When I type the text in the latest Illustrator, the text is in a white box. I never had this problem before. I can't find out how to make the box go away. What I am doing wrong?
Today I tried to close Illustrator and re-boot the computer. It did not help. I went on a second computer video/graphics/animation and open Illustrator here. I did a few tests, and he managed to create the text without a box. Then, I opened my first computer Illustrator file form. The boxes were there. I tried to type the new text, and the box was there. When I open the file it says something about a missing font and a replacement. I tried to use this area to locate the police but couldn't. It's the default font on Illustrator on the other computer. A variant of Myriad. I tried to type in the text with a different font. No box. The default font selected by the Illustrator has apparently a box. I didn't try to change the font because it was going well, and because I didn't know any font came with a box. At first, I did all of the text, which was on a white background, so I don't see the boxes of cream. When I added the background image of the boxes appeared. If the problem is resolved. It was a font with a box.

My printer has been works well, but all of a sudden last week the message came saying "at least one of the cartridges has a problem", so I took the two cartridges to fill them. I discovered they were already full so it wasn't the problem. I was instructed to turn off and unplug the printer, I did several times and still nothing. I bought new cartridges today and that did not help either. All the suggestions that I could try running just to buy a new printer?

How can I get back Admin rights no one has them on the computer?
How can I get back Admin rights no one has them on the computer
IIRC, you cannot delete the built-in account named 'Administrator', so check first to see if it's really over:
If you have XP Pro, then press CTRL + ALT + DELETE twice at the Welcome screen
If you have XP Home (or XP Pro), restart mode without fail (repeatedly press F8 startup just after reboot) and the administrator account must be indicated on the Welcome screen.
Unless you have changed it, the password for the built-in Administrator account is blank (no password).
Once you sign in as an administrator, go to control panel > users and create a new account with administrative privileges (or give these rights to an account existing). Do not use the built-in for common daily tasks administrator account.
