Need help with a 4K Ultra-HD Display, connected to a T530
Hi guys,
the T530 is equipped with an intel HD4000 and a nVidia NVS5400 graphics adapter.
I already found out in this post, that the Display Port (of the comparable T430S) is 1.1 and that instead 1.2 is needed for 4K support.
Has anyone got better news for me, or is the desired 4K-signal stuck inside the Thinkpad forever?
Thank you for your support!
Your MBA should be able to detect the printer and locate the driver, install it and mount the printer. I have an HP5180 color all in one, which I have connected to my Windows PC, and my MBA sees it and prints to it just fine. Have you looked to see if Brother has a Mac driver for it?

Need Help with IMG+PHP Database+Selective Display
The problem is really a lot simpler than I made it sounds to
be, though I fear the answer might be vice versa.
I need to have pictures appear when they exist. That's all.
Here is where I am at:
I have created a php database for a news announcement page.
In that database, I have a column named "img" whose default value
is "null"
Whenever I actually have a picture corrosponding to a
particular news, the "img" column will change to the file name of
that image, which I will then extract.
So basically... if news A, img = null... no picture. news B
img = b... then yes picture. very simple concept for database.
Here's what I can't do.
When I read the database from DW, how can I make it so that
when it reads a "null" it won't insert a picture and vice versa? I
figure it definitely has to do with the "if" statement (duh...)
I know how to make text do that effect...
<? if $row_data['text'] != null
echo("i have data");
?>
but how do i do it with an image? I tried putting the image
tag to replace the entire "echo" line, but that's apparently not
how you do it. I tried putting it inside "echo", but that doesn't
seem to be it either.
also, as a premise, all pictures are associated with only 1
particular news.
which i wrote something similar to this:
<img src="<?php echo $row_data['img']; ?>.jpg"
width="200" height="200" />
Um, basically... I need THAT to fit into the IF statement. So
thanks in advance.if (!is_null($row_data['img']))
echo '<img src="',$row_data['img'],'.jpg" width="200"
height="200" />';
Let's break that down into the following:
echo '<img src="' ;
echo $row_data['img'] ;
echo '.jpg" width="200" height="200" />' ;
When you string multiple echoes together use a comma between
them,. so now
we have:
echo '<img src="',$row_data['img'],'.jpg" width="200"
height="200" />';
(You may also use a period, but my understanding is the
period is less
efficient.)
I only have single quotes in my PHP statements. The double
quotes you see
are part of what will be the rendered HTML.
You may generally use the single quote or double quote
interchangeably with
few exceptions such as having double quotes as part of the
text or vice
versa among others. You can probably escape the characters
too, but lets
keep this simple for now.
If I misspoke I am sure Micha will be sure to correct me.
IMO The best thing to do is learn by trial and error, and
your best resource
on the net for PHP is probably the php website. www.php.net

Need help with image upload and preview display
hi guys,
I'm trying to upload image and then display it as a preview, but when upload form submits to the same page image placeholder does not refreshes it's source and displays the same image as before.
Image 4.jpg already exists.
I upload it with nameConflict = "overwrite"
upload form points to the same page, therefore page reloads
In IE image placeholder does not display the new image, but shows the old one until I refresh the page with F5 and resend information, however if checked, image in the file is already different.
In Firefox, sometimes it works and image refreshes, sometimes not.
any help would be greatly appreciated!
cheers,
SimonHi Daverms,
With your code you suggest to not only upload the image but make a database entry too. However my intention is to firstly upload the file, and show a preview. Then if user is satisfied with what he sees, he presses "aprove" button and therefore makes a datase entry. Then the photo number will increase by one.
Until user is not aproving the photo he can upload any image again and again, but the new image will be always given the same name (example 4.jpg) and overwriting the old one.
I believe the problem persists because browsers are loading image with the same name from the cache, and not from the actual location. Therefore when I refresh the page it catches the correct image.
If I follow your code, every time I upload the image, name of it is different, therefore browser cannot find it in the cache and is forced to load one from the server.
I wonder is there any way to avoid this cache problem?
cheers,

Need help with margins & footer, and browser display issues....
Hello,
I am working on a splash page in Dreamweaver, but am having trouble with the margins and the footer.
1. Margins: I basically want/need the center contents of the page never to extend past the contents of the header and footer.
If you look at the page header, the logo on the top left and "Student and Faculty Portal" should be the margins. Seems to look fine on some users' systems, but not consistent across our department.
2. Footer: I can't seem to figure out how to keep the footer at the bottom without rising above the background image across all browsers & screen sizes. Looks fine on some, but too high or low on others. (Looks the worst when the background image shows underneath the footer).
3. Browser/Screen Size: Depending on which PC I am using, my page changes. At the office, on my 26" monitors, my page looks fine, however, when on different laptops, my right div (that contains the login table) goes under the left. How can I code my page so that it looks consistent on all?
I guess my main complaint/need is for my page to look consistent regardless of screen size, browser or system.
If you could take a look, I would greatly appreciate it.
Your expertise and time is greatly appreciated. I hope I was clear enough, but please let me know if there is any confusion.
http://www.saintleo.edu/PortalLanding/PortalSplash.html
Kind regards,
JK1. Create a div around your content, give it a width and margin: 0 auto;
2. Follow this tutorial. It will be a lifesaver and it sounds like what you are trying to do: http://css-tricks.com/snippets/css/sticky-footer/
3. See #1. In addition, remove right-margin from login box, add float: right; and remove float: left; from main content. -
Need help with a form where checkbox displays another field
I created a from in january that works perfectly. I have different departments as checkboxes and if the box is checked, it displays another subform with a comments, approval, and signature field. However, we just added two new departments. I copied one of the checkboxes and subsequent fields twice. I then changed the script for the approriate field and checked to make sure there were no other functions I was missing. However, now when I open the form, the two new fields show by default. If I check the box and uncheck, the associated subform disappears. I think there may be some simple thing i am overlooking.
I'm not getting any errors at all. The form isn't online as of yet so I dont have a link. I will attach a screen shot and maybe you can tell me where I went wrong.

Need help with not working timer Hp Display Assistant
Hello i got monitor LA 2306v and when i want use "timer" option in Hp Display Assistant it doesn't work "sheduler" options fork perfect but "timer" one at all :/ Using Windows Vista home premium and got newest version of Hp Display Assistant.
ill be rly grateful for help thanksThe following was taken from here.
HP Display Assistant is a Windows-based software utility designed for select HP displays that support
the Display Data Channel/Command Interface (DDC/CI) communications channel defined by the Video
Electronics Standards Association (VESA). HP Display Assistant does not function on non-HP displays
(including non-HP displays that support DDC/CI), and does not function on HP displays that do not
support DDC/CI. For a list of leading graphics cards that support HP Display Assistant:
1. Open HP Display Assistant.
2. Click the Options tab.
3. Click the Help button.
4. Click the Tech. Support button to open the HP Display Assistant online support Web page.
5. Click the Compatibility link on the Web page.
Is the computer's video card on the supported/compatible list? If the video card does not support the feature, then the program won't work.
Let me know if the computer's graphics card is on the list.
Also, report what graphics card the system is using.
I await your reply.

Need help with my kt3 ultra (only 127gigs maximum supported)
Hi, I have a 163 gigs hd and it show 163 when i start my computer. but in windows its still show 127 gigs.
I installed sp1 and it didnt help,now i tried this http://support.microsoft.com/default.aspx?scid=kb;en-us;303013
and its not working.
If someones know what is the problem pls say it,i dont know if its my bios..because it supose to support 160gigs+, and when i start my computer it show 163 like I said.According to the specs for that board it supports upto 160gb I dont know if that means they havent tested it with anything higher or that anything higher wont work.
As it shows the correct size when starting the computer I dont think its a problem with the board.
What version of the bios is it?
I'm not sure if the bois supports 48-bit LBA but i think it should as it can reciognise the correct amount on start-up.
Are you certain you did exactly what the support page asked.
Another option maybe to partition the hard drive not sure if it would work but its just a thought.

Need Help with Address Display
I need help with APEX.
Here's my situation:
I have a report that displays brief employee information. Among the information displayed is the Address. Right now, it's display as:
Mr X
Employee Id
Accounting Department
Address 1
Mr X
Employee Id
Accounting Department
Address 2
I would like it to display
Mr X
Employee Id
Accounting Department
Address 1
Address 2
1) I have thought of using the Break functionality; however, the function only allows break at column 1, 2, 3. As you can see Address starts at column 4. Also, Address has a few columns; Address Line 1, Address Line 2, City, State, Zipcode.
2) Stragg functions - I'm not sure how to implement it since it has more than 1 columns.
Any ideas?
Thanks in advance
AndrewThe example I gave you, using analytic functions is a simple one.
Now, you are saying:
1. some of the employees may have two adresses?
2. if this is the case, your employee appears in the report twice?
3. you don't want his name, employee id and accounting department to appear twice?
4. only his address has to be displayed?
If the answer to all the questions is yes, this kind of query will help you. I repeat:
SELECT CASE
WHEN LAG (employee_id) OVER (ORDER BY employee_id) =
employee_id
THEN NULL
ELSE employee_name
END employee_name,
CASE
WHEN LAG (employee_id) OVER (ORDER BY employee_id) =
employee_id
THEN NULL
ELSE employee_id
END employee_id,
CASE
WHEN LAG (employee_id) OVER (ORDER BY employee_id) =
employee_id
THEN NULL
ELSE accounting_department
END accounting_department,
street, postal_code, city, state, country
FROM your_employees_table;Give it a try.

I need Help with a website I've created
I need help with a website I've created (www.jonathanhazelwood.com/lighthouse) I created the folowing site with dreamweaver at my current resolution 1366 by 768. Looks great on my screen resolution but if it is viewed on other resolutions the menu moves and some of the text above and below. How can I keep all content centered and working like it does on 1366 by 768 on all resolutions. The htm to my site is below I started off with a blank template through dreamweaver CS5.

<p> Special Message from Perry Stone </p>
<h2> Was Jesus Born on December 25?</h2>
<p> 12/20/2010 </p>

<p>Last year, in response to the growing number of Christians who celebrate Hanukkah but hate Christmas, I wrote an article for this website titled “Hanukkah or Christmas?” I explained why I think Jesus was either conceived or birthed on December 25.</p>

</html>Look at all the apdiv's you have. Those are absolutely positioned layers. I'm assuming by your post that you are very new to Dreamweaver and HTML and CSS. I would highly recommend not using absolutely positioned layers until you have a better grasp on HTML and CSS.
Looking at your code I would suggest that you consider using one of Dreamweaver's built in, or downloadable templates as a starting point and work from there.

Need help with calculator project for an assignment...
Hi all, I please need help with my calculator project that I have to do for an assignment.
Here is the project's specifications that I need to do"
"""Create a console calculator applicaion that:
* Takes one command line argument: your name and surname. When the
program starts, display the date and time with a welcome message for the
user.
* Display all the available options to the user. Your calculator must include
the arithmetic operations as well as at least five scientific operations of the
Math class.
-Your program must also have the ability to round a number and
truncate it.
-When you multiply by 2, you should not use the '*' operator to perform the
operation.
-Your program must also be able to reverse the sign of a number.
* Include sufficient error checking in your program to ensure that the user
only enters valid input. Make use of the String; Character, and other
wrapper classes to help you.
* Your program must be able to do conversions between decimal, octal and
hex numbers.
* Make use of a menu. You should give the user the option to end the
program when entering a certain option.
* When the program exits, display a message for the user, stating the
current time, and calculate and display how long the user used your
program.
* Make use of helper classes where possible.
* Use the SDK to run your program."""
When the program starts, it asks the user for his/her name and surname. I got the program to ask the user again and again for his/her name and surname
when he/she doesn't insert anything or just press 'enter', but if the user enters a number for the name and surname part, the program continues.
Now my question is this: How can I restrict the user to only enter 'letters' (and spaces of course) but allow NO numbers for his/her surname??
Here is the programs code that I've written so far:

Now my question is this: How can I restrict the user to only enter 'letters' (and spaces of course) but allow NO numbers for his/her surname??You cannot restrict the user. It is a sad fact in programming that the worst bug always sits in front of the Computer.
What you could do is checking the input string for numbers. If it contains numbers, just reprompt for the Name.
AND you might want to ask yourself why the heck a calculator needs to know the users Name. -
Need help with Berkeley XML DB Performance
We need help with maximizing performance of our use of Berkeley XML DB. I am filling most of the 29 part question as listed by Oracle's BDB team.
Berkeley DB XML Performance Questionnaire
1. Describe the Performance area that you are measuring? What is the
current performance? What are your performance goals you hope to
achieve?
We are measuring the performance while loading a document during
web application startup. It is currently taking 10-12 seconds when
only one user is on the system. We are trying to do some testing to
get the load time when several users are on the system.
We would like the load time to be 5 seconds or less.
2. What Berkeley DB XML Version? Any optional configuration flags
specified? Are you running with any special patches? Please specify?
dbxml 2.4.13. No special patches.
3. What Berkeley DB Version? Any optional configuration flags
specified? Are you running with any special patches? Please Specify.
bdb 4.6.21. No special patches.
4. Processor name, speed and chipset?
Intel Xeon CPU 5150 2.66GHz
5. Operating System and Version?
Red Hat Enterprise Linux Relase 4 Update 6
6. Disk Drive Type and speed?
Don't have that information
7. File System Type? (such as EXT2, NTFS, Reiser)
EXT3
8. Physical Memory Available?
4GB
9. Are you using Replication (HA) with Berkeley DB XML? If so, please
describe the network you are using, and the number of Replica’s.
No
10. Are you using a Remote Filesystem (NFS) ? If so, for which
Berkeley DB XML/DB files?
No
11. What type of mutexes do you have configured? Did you specify
–with-mutex=? Specify what you find inn your config.log, search
for db_cv_mutex?
None. Did not specify -with-mutex during bdb compilation
12. Which API are you using (C++, Java, Perl, PHP, Python, other) ?
Which compiler and version?
Java 1.5
13. If you are using an Application Server or Web Server, please
provide the name and version?
Oracle Appication Server 10.1.3.4.0
14. Please provide your exact Environment Configuration Flags (include
anything specified in you DB_CONFIG file)
Default.
15. Please provide your Container Configuration Flags?
final EnvironmentConfig envConf = new EnvironmentConfig();
envConf.setAllowCreate(true); // If the environment does not
// exist, create it.
envConf.setInitializeCache(true); // Turn on the shared memory
// region.
envConf.setInitializeLocking(true); // Turn on the locking subsystem.
envConf.setInitializeLogging(true); // Turn on the logging subsystem.
envConf.setTransactional(true); // Turn on the transactional
// subsystem.
envConf.setLockDetectMode(LockDetectMode.MINWRITE);
envConf.setThreaded(true);
envConf.setErrorStream(System.err);
envConf.setCacheSize(1024*1024*64);
envConf.setMaxLockers(2000);
envConf.setMaxLocks(2000);
envConf.setMaxLockObjects(2000);
envConf.setTxnMaxActive(200);
envConf.setTxnWriteNoSync(true);
envConf.setMaxMutexes(40000);
16. How many XML Containers do you have? For each one please specify:
One.
1. The Container Configuration Flags
XmlContainerConfig xmlContainerConfig = new XmlContainerConfig();
xmlContainerConfig.setTransactional(true);
xmlContainerConfig.setIndexNodes(true);
xmlContainerConfig.setReadUncommitted(true);
2. How many documents?
Everytime the user logs in, the current xml document is loaded from
a oracle database table and put it in the Berkeley XML DB.
The documents get deleted from XML DB when the Oracle application
server container is stopped.
The number of documents should start with zero initially and it
will grow with every login.
3. What type (node or wholedoc)?
Node
4. Please indicate the minimum, maximum and average size of
documents?
The minimum is about 2MB and the maximum could 20MB. The average
mostly about 5MB.
5. Are you using document data? If so please describe how?
We are using document data only to save changes made
to the application data in a web application. The final save goes
to the relational database. Berkeley XML DB is just used to store
temporary data since going to the relational database for each change
will cause severe performance issues.
17. Please describe the shape of one of your typical documents? Please
do this by sending us a skeleton XML document.
Due to the sensitive nature of the data, I can provide XML schema instead.
18. What is the rate of document insertion/update required or
expected? Are you doing partial node updates (via XmlModify) or
replacing the document?
The document is inserted during user login. Any change made to the application
data grid or other data components gets saved in Berkeley DB. We also have
an automatic save every two minutes. The final save from the application
gets saved in a relational database.
19. What is the query rate required/expected?
Users will not be entering data rapidly. There will be lot of think time
before the users enter/modify data in the web application. This is a pilot
project but when we go live with this application, we will expect 25 users
at the same time.
20. XQuery -- supply some sample queries
1. Please provide the Query Plan
2. Are you using DBXML_INDEX_NODES?
Yes.
3. Display the indices you have defined for the specific query.
XmlIndexSpecification spec = container.getIndexSpecification();
// ids
spec.addIndex("", "id", XmlIndexSpecification.PATH_NODE | XmlIndexSpecification.NODE_ATTRIBUTE | XmlIndexSpecification.KEY_EQUALITY, XmlValue.STRING);
spec.addIndex("", "idref", XmlIndexSpecification.PATH_NODE | XmlIndexSpecification.NODE_ATTRIBUTE | XmlIndexSpecification.KEY_EQUALITY, XmlValue.STRING);
// index to cover AttributeValue/Description
spec.addIndex("", "Description", XmlIndexSpecification.PATH_EDGE | XmlIndexSpecification.NODE_ELEMENT | XmlIndexSpecification.KEY_SUBSTRING, XmlValue.STRING);
// cover AttributeValue/@value
spec.addIndex("", "value", XmlIndexSpecification.PATH_EDGE | XmlIndexSpecification.NODE_ATTRIBUTE | XmlIndexSpecification.KEY_EQUALITY, XmlValue.STRING);
// item attribute values
spec.addIndex("", "type", XmlIndexSpecification.PATH_EDGE | XmlIndexSpecification.NODE_ATTRIBUTE | XmlIndexSpecification.KEY_EQUALITY, XmlValue.STRING);
// default index
spec.addDefaultIndex(XmlIndexSpecification.PATH_NODE | XmlIndexSpecification.NODE_ELEMENT | XmlIndexSpecification.KEY_EQUALITY, XmlValue.STRING);
spec.addDefaultIndex(XmlIndexSpecification.PATH_NODE | XmlIndexSpecification.NODE_ATTRIBUTE | XmlIndexSpecification.KEY_EQUALITY, XmlValue.STRING);
// save the spec to the container
XmlUpdateContext uc = xmlManager.createUpdateContext();
container.setIndexSpecification(spec, uc);
4. If this is a large query, please consider sending a smaller
query (and query plan) that demonstrates the problem.
21. Are you running with Transactions? If so please provide any
transactions flags you specify with any API calls.
Yes. READ_UNCOMMITED in some and READ_COMMITTED in other transactions.
22. If your application is transactional, are your log files stored on
the same disk as your containers/databases?
Yes.
23. Do you use AUTO_COMMIT?
No.
24. Please list any non-transactional operations performed?
No.
25. How many threads of control are running? How many threads in read
only mode? How many threads are updating?
We use Berkeley XML DB within the context of a struts web application.
Each user logged into the web application will be running a bdb transactoin
within the context of a struts action thread.
26. Please include a paragraph describing the performance measurements
you have made. Please specifically list any Berkeley DB operations
where the performance is currently insufficient.
We are clocking 10-12 seconds of loading a document from dbd when
five users are on the system.
getContainer().getDocument(documentName);
27. What performance level do you hope to achieve?
We would like to get less than 5 seconds when 25 users are on the system.
28. Please send us the output of the following db_stat utility commands
after your application has been running under "normal" load for some
period of time:
% db_stat -h database environment -c
% db_stat -h database environment -l
% db_stat -h database environment -m
% db_stat -h database environment -r
% db_stat -h database environment -t
(These commands require the db_stat utility access a shared database
environment. If your application has a private environment, please
remove the DB_PRIVATE flag used when the environment is created, so
you can obtain these measurements. If removing the DB_PRIVATE flag
is not possible, let us know and we can discuss alternatives with
you.)
If your application has periods of "good" and "bad" performance,
please run the above list of commands several times, during both
good and bad periods, and additionally specify the -Z flags (so
the output of each command isn't cumulative).
When possible, please run basic system performance reporting tools
during the time you are measuring the application's performance.
For example, on UNIX systems, the vmstat and iostat utilities are
good choices.
Will give this information soon.
29. Are there any other significant applications running on this
system? Are you using Berkeley DB outside of Berkeley DB XML?
Please describe the application?
No to the first two questions.
The web application is an online review of test questions. The users
login and then review the items one by one. The relational database
holds the data in xml. During application load, the application
retrieves the xml and then saves it to bdb. While the user
is making changes to the data in the application, it writes those
changes to bdb. Finally when the user hits the SAVE button, the data
gets saved to the relational database. We also have an automatic save
every two minues, which saves bdb xml data and saves it to relational
database.
Thanks,
Madhav
[email protected]Could it be that you simply do not have set up indexes to support your query? If so, you could do some basic testing using the dbxml shell:
milu@colinux:~/xpg > dbxml -h ~/dbenv
Joined existing environment
dbxml> setverbose 7 2
dbxml> open tv.dbxml
dbxml> listIndexes
dbxml> query { collection()[//@date-tip]/*[@chID = ('ard','zdf')] (: example :) }
dbxml> queryplan { collection()[//@date-tip]/*[@chID = ('ard','zdf')] (: example :) }Verbosity will make the engine display some (rather cryptic) information on index usage. I can't remember where the output is explained; my feeling is that "V(...)" means the index is being used (which is good), but that observation may not be accurate. Note that some details in the setVerbose command could differ, as I'm using 2.4.16 while you're using 2.4.13.
Also, take a look at the query plan. You can post it here and some people will be able to diagnose it.
