How to run hardware diagnostics for an Intel Mac
Boot from your original OS X Installer Disc One that came with your computer. After the chime press and hold down the "D" key until the diagnostic screen appears. Run the extended tests for a minimum of two or three hours. If any error messages appear note them down as you will need to report them to the service tech when you take the computer in for repair.
Some "common" error indicators:
SNS - sensor error
MEM - memory error
HDD - hard disk drive error
MOT - fan error

How do I check for bad sectors on the hard drive? (Need help soon!)

I've asked this in a different thread but am not getting exactly the question answered completely. I need to run a check on my drive that will test each sector and if a bad sector is found, it will block that sector from being written to with data in the future.
I used to use Disk First Aid or Apple HD Setup or Norton Utilities to do this. Norton does not appear to be made for Mac OSX 10.4.4 and those other utilities appear to be System 9 and earlier utilities only.
Is there some way of doing this with current Apple tools? My original post is at http://discussions.apple.com/thread.jspa?messageID=1592160#1592160
Thank you. I've been down since Saturday and really need to get an answer so I can move forward and get my computer back up and running.

There is only one way to do this. Make a bootable backup of your drive to an external Firewire drive (you can use the Restore option of Disk Utility.) Then do the following:
1 Boot from your Tiger DVD. After the installer loads select Disk Utility from the Utilities.
2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Click on the Partition tab in the DU main window.
3. Set the number of partitions from the dropdown menu (use 1 partition unless you wish to make more.) Set the format type to Mac OS Extended (Journaled, if supported.) Click on the Partition button and wait until the volume(s) mount on the Desktop.
4. Select the volume you just created (this is the sub-entry under the drive entry) from the left side list. Click on the Erase tab in the DU main window.
5. Set the format type to Mac OS Extended (Journaled, if supported.) Click on the Options button, check the button for Zero Data and click on OK to return to the Erase window.
6. Click on the Erase button. The format process will take 30 minutes to an hour or more depending upon the drive size.
By reformatting using the Zero Data option DU will force checking for bad blocks.
If you wish to forego the above procedure you can purchase TechTool Pro (v. 4.1.1) which has a module for scanning the disk for bad blocks. However, repairing the drive can only be done by reformatting.

Hi Matthias,
Sorry, if this reply seems like a products plug (which it is), but this is really how we solve this software engineering challenge at JKI...
At JKI, we create VI Packages (which are basically installers for LabVIEW instrument drivers and toolkits) of our reusable code (using the package building capabilities of VIPM Professional). We keep a VI Package Configuration file (that includes a copy of the actual packages) in each of our project folders (and check it into source code control just as we do for all our project files). We also use VIPM Enterprise to distribute new VI Packages over the network.
Also, as others have mentioned, we use the JKI TortoiseSVN Tool to make it easy to use TortoiseSVN directly from LabVIEW.
Please feel free to contact JKI if you have any specific questions about these products.
Thanks,
-Jim

How does APEX check for null values in Text Fields on the forms?

Hello all,
How does APEX check for null values in Text Fields on the forms? This might sound trivial but I have a problem with a PL/SQL Validation that I have written.
I have one select list (P108_CLUSTER_ID) and one Text field (P108_PRIVATE_IP). I made P108_CLUSTER_ID to return null value when nothing is selected and assumed P108_PRIVATE_IP to return null value too when nothign is entered in the text field.
All that I need is to validate if P108_PRIVATE_IP is entered when a P108_CLUSTER_ID is selected. i.e it is mandatory to enter Private IP when a cluster is seelcted and following is my Pl/SQL code
Declare
v_valid boolean;
Begin
IF :P108_CLUSTER_ID is NULL and :P108_PRIVATE_IP is NULL THEN
v_valid := TRUE;
ELSIF :P108_CLUSTER_ID is NOT NULL and :P108_PRIVATE_IP is NOT NULL THEN
v_valid := TRUE;
ELSIF :P108_CLUSTER_ID is NOT NULL and :P108_PRIVATE_IP is NULL THEN
v_valid := FALSE;
ELSIF :P108_CLUSTER_ID is NULL and :P108_PRIVATE_IP is NOT NULL THEN
v_valid := FALSE;
END IF;
return v_valid;
END;
My problem is it is returning FALSE for all the cases.It works fine in SQL Command though..When I tried to Debug and use Firebug, I found that Text fields are not stored a null by default but as empty strings "" . Now I tried modifying my PL/SQL to check Private_IP against an empty string. But doesn't help. Can someone please tell me how I need to proceed.
Thanks

See SQL report for LIKE SEARCH I have just explained how Select list return value works..

How can I check for the existence of an XML file in Illustrator Javascript??

I'm writing a Javascript to run at startup. I want to check for the existence of XML files and process them, if they are available. How can I check for their existence?

Your first line just sets a variable to a string value… getFiles() is a method of Folder… so
var InputXMLDir = Folder( "D:/Brackets/Create_Bracket_Graphics/Input/XML-n-Templates/" );
Not a PC user so I can't remember if the colon is OK…? As you appear to know the file name why bother with a folder get files anyhow you could just check if the file exists then do some thing…
alert( File( "D:/Brackets/Create_Bracket_Graphics/Input/XML-n-Templates/brackets_men_web.xml" ).exists );

Carriage return in textarea - how do I check for and remove it???

I have an html form that has a <textarea> element for user input. I work mainly with Java and some JavaScript. Since carriage returns are permitted in a <textarea> element, upon retrieving the value submitted, my Java and/or JavaScript variables contain carriage returns as well, making the values incomplete.
For Example :
String dataSubmitted = request.getParameter("formInput");
<script language="JavaScript">
var textValue = "<%=dataSubmitted%>";
....//do other stuff
</script>When I view the source of my JSP page, the above statement of code looks like this:
var textValue = "This is some text that
I submitted with a carriage return";I'm putting the text submitted through this form into a mysql database, and when I pull up the values I find that it has recorded the carriage return as well. There is an actual symbol representing a carriage return in the db field.
What I'd like to do is use some Java code to go through each character of the String and find and remove the carriage return, perhaps replacing it with an empty space instead. But how do I check for a carriage return in a String variable?
Also, is there a way to use JavaScript to alert the user when the carriage return button is pressed when they're in the <textarea>?
Any input is appreciated,
Thank You,
-Love2Java

What I'd like to do is use some Java code to go through
each character of the String and find and remove the
carriage return, perhaps replacing it with an empty
space instead. But how do I check for a carriage return
in a String variable?The carriage return is represented by the \r. Generally there is also a newline, the \n. You can use String#replaceAll() to replace occurences of them by a space.
string = string.replaceAll("\r\n", " ");
Also, is there a way to use JavaScript to alert the user
when the carriage return button is pressed when they're
in the <textarea>?You can capture keys using the 'onkeypress' attribute. The keyCode of a the return key is 13. So simply catch that:<textarea onkeypress="if (event.keyCode == 13) alert('You pressed the return button.'); return false;"></textarea>The return false prohibits the linebreak being inserted. If you remove that, then it will be inserted anyway.

Actually, it's a timing issue. Those items are greyed out for a couple of minutes after PPro starts. A little patience and they become available. ;)

Thanks.

Usually the best way is by contacting the manufacturer of the peripheral. Manufacturers have the best information for compatibility with other devices for their products.

HT1752 how can I check for SpyBots and other invasion things on my computer

I am beginning to have odd things happen to my computer. Someone told me to check for SpyBots, but I don't know how. I participate on Blog Talk Radio, and was informed they use these spybot things. How do I find out if there are invasive things like this affecting my computer?
In the last 2 days I've had two windows pop up saying I needed to restart the computer. This has never happened before. Any help anyone?

Forget about the advise on the spybots. That person doesn't have the foggiest idea what is going on.
You are having kernel panics. The most likely casue for kernel panics is hardware problems usually RAM that has gone bad.
Go to http://thexlab.com/faqs/kernelpanics.html for a good procedure on how to find out what is causing the kernel panics.

How do I check for Malware? I have a 4giga IMac and she is using 3.9 only running Safari.

I have IMac OSX 10.9.4, 4GB,Processor 3.06 with Intell2Duo. I would like to check for Malware. I run a TechTool Pro 6 every month and that comes up great.
When check how much memory I am using, with only Safari open I am using 3.9 and more of her 4.0 memory. She is very. very slow in processing. I had 4000
trash to clean out and it took her over an hour to expel. Also for some reason Safari will not allow me to click on a link, in my G-mail, and let it go to the page.
It has a sign saying a pop-up blocker is on and will not let me do it. I must open the stamp to look at my e-mails and if I have redirected link now I can do it.
I have not changed my preferences so where is this pop-up blocker?
I have looked at preferences on Safari and Google, which I do not understand Google, and do not see where this blocker could be.
Malware is something I want to make sure is not on my computer. Tech Tool Pro 6 is all I know of and it does not detect Malware.
Help.

Your not running windows.
Apple provides malware detection and removal as part of Mac OS X. A lot of the mac os x supposedly malware detection tools are malware themselves.
When check how much memory I am using, with only Safari open I am using 3.9 and more of her 4.0 memory.
Mac OS X uses all the memory it can to improve performance. I'm not familiar with Mavericks to know if this is a problem or not.
She is very. very slow in processing
This is a problem. Doesn't mean you have malware. You could have installed some app with a bug, etc.
1) You want to look in
/Applications/Utilities/activity monitor
& see what the problem apps are.
2) Run etrecheck. Post results here. The author of this tool partipates in ASC.

Can I exit from paintComponent? ...or... how can I check for invalid data?

I'm writing a calendar applet for a programming class and I've nearly completed it but I'm stuck at checking for valid data.
What seems to be happening is that paintComponent() is being called before actionPerformed.
In actionPerformed (when they click the button), it checks to make sure they entered a valid month (1 to 12). If the didn't it dispalys a message, but if they did it calls repaint().
But even if repaint() isn't called, Java still seems to call it before actionPerformed and I get exceptions.
So I tried checking inside of paintComponent() by using a simple if(...) return; but that doesn't seem to do anything... it just keeps going through with the method.
So -- Once the user presses my button I want to make sure the data is valid before repainting the screen. How can I do this?

I validate it in actionPerformed which is called by
the action listener... that is what you meant right?
The problem is that it seems paintComponent() is being
called before I can validate the data with
actionPerformed(). I need to stop paintComponent()
from always being calledMVC. (Model, View, Controller)
Initially the internal value of the data (the model) should be valid (or null with a check in the paintComponent method)
paintComponent (the view part) shows the state of the valid data.
You press the button.
actionPerformed is called (the controller).
It checks the value and, if valid, writes it to the data (model), then updates the view.
At no point will the view have to render invalid data, because the model is only updated after actionPerformed checks the value.
The pattern may be applied with different classes performing the three roles, or different methods in the same class (sometimes it's easier that way for simple cases).

How can I check for directory creation?

Hi,
I want to check whether I can create a directory at a particular location.
Let's say at c:\windows, can create a directory called c:\windows\mydir. But I won't be knowing the parent location (i.e., c:\windows here) at compile time.
And I would also like to check for creating a directory like c:\windows\mydir1\mydir2 (mydir1 may not even exist).
What I was doing was, I created the file object for my new directory (i.e., mydir here) and used the canWrite() method on the parent directory. But this method worked only when the parent directory existed. But how can check for a directory path like c:\windows\mydir1\mydir2 where I have to create both mydir1 for mydir2.
Is there any other methods that I can use to perform this kind of a check.
Thank you

I finally figured out a workaround, but i don't know whether this is a good way of checking. :)
import java.io.File;
public class TryMKDIRs {
     public static void main(String[] args) {
          File file = new File("c:\\mydir1\\mydir2\\mydir3");
          boolean canICreateDir = false;
          if(false == (canICreateDir = file.canWrite())) {
               System.out.println(file.getAbsoluteFile() + " cannot be created.");
               File fileparent = file.getParentFile();
               while(fileparent != null && (canICreateDir = fileparent.canWrite()) == false) {
                    System.out.println(fileparent.getAbsoluteFile() + " cannot be created.");
                    fileparent = fileparent.getParentFile();
          if(canICreateDir) {
               file.mkdirs();
               System.out.println("Directory can be created. . .");
}
