How can I check if a certain resource u3d is attached to a 3D (JavaScript) annotation?
I have a number of u3d files attached to a 3D annotation.
Can I insert one of them in the scene by:
var u3dResource = new Resource("pdf://" + <theName> + ".u3d"); scene.addModel(u3dResource); |
If there is no such resource, u3dResource is not undefined or null or... but a resource of type object.
Using this object translates the message Line: 02: Code: 45 (0x2d): object is not valid but there is no exception to be caught.
How can I check if the resource exists or if u3dResource is a valid purpose?
Example:
U3D = new resource ("pdf://example.u3d");
If {(u3d.type===undefined)}
Console.println ("the model is missing or corrupted");
} else {}
do your other stuff
}
Exceptions are still echo to the console - it's why we call it the console debugger - but unless they are deadly, that it is not serious.

If two objects are the same resource in the library, how can I check it?
Seen as below in the code, I created two objects of an object in the library. When you click it, the trace says
object sample_mc for both. So, how can I check it in the code if several objects are of the same resource of the library...
var a1:MovieClip = new sample_mc();
var a2:MovieClip = new sample_mc();
var arr:Array = new Array();
addChild (a1);
addChild (a2);
A1.x = 50;
A1.y = 50;
A2.x = 150;
A2.y = 50;A1.addEventListener (MouseEvent.Click, f_achil);
A2.addEventListener (MouseEvent.Click, f_achil);
function f_achil(event:MouseEvent):void {}
trace (Event.Target);
If (arr. Length < 2) {}
arr.push (Event.currentTarget) ;}
trace ("arr:" + arr);
{if(arr[0]==arr[1])}
trace ("OK") ;}
}Yes! But there is a work around to get the class name using the getQualifiedClassName . Now you get success. under the rocks of code for you:
If (getQualifiedClassName (Object(arr[0])) == getQualifiedClassName (Object(arr[1])))
trace ("OK");It will now compare with your class name at last. Cast object is optional.

Satellite U200-181: How can I check if the TPM Module is present
How can I check Trusted Platform module is present or not?
Hello
The TPM module (trusted platform module module) configuration is done in the BIOS Setup program, and this feature is available only with certain models.
I put t know if the U200-181 is favorable or not, but you can check it out yourself.
Safety controller parameters should be available in the system BIOS Setup on the second site.
If the device supports the TPM module, you should see the switch to enable or disable this security option. Generally according to the default TPM module is disabled. -
How can I check the disc for physical integrity on Satellite P305?
I have P305-S8838.
I had some freezing problems earlier this month, and on the notice here, I nu start-up and reduced services a little at a time.
Now, I have a few more crash but don't know if it's a physical disk problem.For example... I have run CHKDSK and does many things and happens at the exact same spot and hangs at step 4 file 5 3498 or 421168 processed.
I tried to run CHKDSK in SafeMode but tells me drive is locked and it will run when I restart. But the restart put back me in normal mode and get the same hang.
Now, for more suspicion of a physical problem. I tried to make a disk image with ACronis and same problem occurs because he says impossible to reading data 226 964, 072 sector and ask if I want to ignore and continue. I say yes to everything. Log shows he made about three of these attempts and crashes.
I ran sfc/scannow and it says found problems that he was unable to fix. The newspaper isn't so long and complex course that all means. I could send these log files if someone can help me understand.
I ran the test of memory OK.
I if I could put in DVD Toshiba and certain diagnoses, but when I put in the disk I get this big warning I'll crush, etc and I have chicken.
This didn't stop me to use the computer, but its all irritating.

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

each installation.Always check in the Device Manager - drivers tab to be sure the version you actually install

How can I check my Mac mini for spyware and other viruses
How can I check my Mac mini for software spyware and other forms of virus? Recently, I received an electronic invoice which seems to come from Apple on a purchase that I did not. Unfortunately, I answered by clicking on a link that asked me to cancel or manage this purchase that led me to a site that didn't look like an official Apple site. I am afraid that simply by doing so, I welcomed the spyware on my Mac mini hard drive.
My Mac was purchased in 2011 and runs on OS X El Capitan (version 10.11.6).
Kind regards
Politkovskaya
Receive a fraudulent e-mail for a purchase confirmation, you did not is a very common scam. Remember that you are not misled by providing personal information solicited by this e-mail.
Unfortunately, I answered by clicking on a link that asked me to cancel or manage this purchase that led me to a site that didn't look like an official Apple site. I am afraid that simply by doing so, I welcomed the spyware on my Mac mini hard drive.
No harm will come of the fact that you wrote. Fraudulent Web sites that are made to appear as legitimate those who are specially designed to convince you to reveal personal information. If you don't have that, no further action is necessary or justified. Do not install anything, no matter the source or the apparent popularity, in response to one such scam. To do this would be the first step in a path well worn to the misery.
On the other hand, if you were tricked into providing personal information (like your Apple ID and password) you will need to change your password on Apple ID. Please write back for instructions.

How can I check the battery on 4S?
I have an old iPhone 4S. Lately, it seems the need to run down like its drain more, but little or no running applications. I have try to disable wifi not at home so that it tries to connect to those that I can't use. But the battery I don't know maybe just petering. How can I check to see how healthy is it? I'm in iOS 9.3.5. I'm not running the location Services for ex. But ask how can I see how many times he's been charged, or there at - it a good free or paid software that will tell me his health? Sounds to the purchase of new phone 5 or higher at some point, but cannot yet.
Try the 'Autonomy' application or make an appointment at the Genius Bar at your local Apple store. They will test the battery for you.

How can I check the validity of an email allegedly from apple?

I doubt very seriously that it is legitimate to Apple. Do not click on links in the e-mail or enter information in any website referenced in the email.
The following bandages may be useful:

How can I check my journal/password of e-mail on settings?
MOM Gets an error of the Charter, saying: invalid username or password.
How can she check this information?
I tried to do it on my thunderbird and either cannot understand. But then again im not having problems.
Not sure if shes getting every time or intermittently, have asked, but she has not responded yet.And the Charter is KNOWN for having email problems...
Depends on what it means CHECK.
If you want to confirm that you really know your username and password go to the Charter webmail page and log on to the account there. If it works, you have passed the test. If it doesn't then look for a link reset the password that you can remember.
Follow these instructions to see what has been recorded in Thunderbird or to remove and replace the password recorded by a new to match any new password that you create with the Charter.

Any advice on this program or if there is a similar program to download youtube, who is known to be squeaky clean?
Too, I have youtube downloader video and audio 0.3.5 by Chris on FF but have not used a lot or not at all. Today, Avast gave me a warning (probably a Malware DB recent update) that this product has very bad side. My two main concerns are a possible Trojan and adware popups - horse for now that I only have those on a single site, The Pirate Bay, but they are devilishly difficult to get rid of.
Avast and some other malware utilities not come with Trojan horses, but I saw a EULA (on Board of another, may not be the same product) which explicitly stated the software would share information on the internet, probably tunnel through the firewall. Malware utilitie which would detect as a Trojan horse, or that they would assume that I installed it intentionally? How do they know?
Are modules which arise on the FF Add-ons Manager > get guaranteed by Mozilla addons?
