How can i equal String with blanks?

why this code doesn't work:
String paramValue = prmValues;
if(paramValue.equals("")) paramValue="No Value";
Any suggestion would be appreciate.

It realaly depends on what prmValue is. If prmValue = "" then that would work. I've assumed that prmValue is a String and it is = "".
Try using code like this to test it out. It worked for me.
public class Test
     public static void main(String[] args)
          String prmValue = "";
          String paramValue = prmValue;
          if (paramValue.equals(""))
               paramValue = "No Value";
          else
               paramValue = "Error";
          System.out.println(paramValue);
btw it wont work for prmValue = null or if prmValue wasn't initialised.

How can I start firefox with new tab instead of blank page?

Today I update firefox to 13.0. I like the new "new type". I want to konw how can I start firefox with new tab instead of blank page?
I don't want to change the homepage to about:newtab.
Sorry for my bad English.

This is a very annoying thing. Every update from Firefox resets this config setting back to about:newtab. I changed '''''browser.newtab.url''''' in 12.x to '''''about:blank''''' and it resetted back in update 13.0 and now I have to do the same thing again in 13.0.1.
The drawback with about:newtab is Firefox opens up dataports for every URL that are linked and gets reopened for every lame 'newtab' you click on. Just use [http://technet.microsoft.com/en-us/sysinternals/bb897437.aspx Tcpview - data port viewer] and watch how many extra dataports that opens up from this crazy 'feature'.

New iPad Air 2 (December 2014) with a persisting blank screen. Support site suggests a restore after turning off 'Find my iPhone' on the device. How can I do this with a blank screen?

Thanks JimHdk,
After a little more searching across various online resources I was able to cure it by holding down the home button and the on/off button for 10 seconds to restart it and it all came back with a clear screen.

Hi,
actually there's none. The UITableView class needs to "know" the tableView's height so either it can calc <number of rows> times <row height> or it has to sum the height of each single row.
If the row which needs to be of different size always is the first or the last row you can user a tableHeader or tableFoot view.

How can I use TrueSequenceFactory with multiple sequences

In the post "How to use existing Oracle sequences using KODO" answered
by Marc Prud'hommeaux a "sample code" was given. But seems to me that
example will only work with a single Oracle sequence for the entire
system. Is this right?
How can I use TrueSequenceFactory with primary-keys and their
respective existing sequences? Can you (SolarMetric guys) provide me a
sample code?

The problem is that you are using application-identity. When you
specify an objectid-class, we treat is automatically as application
identity. To resolve this, I would recommend removing both the
objectid-class and identity-type atributes from your class. With
"objectid-class" in place, we asssume that you wil take care of identity.

I'm using Kodo 2.4.0, Oracle 9i, JBoss 3.0.4, the Kodo jars are in the
JBoss' lib/ext.
Well, I'll show what I have...
This is the script of my table:
CREATE TABLE LINEUP_VOYAGE (
VOYAGEID NUMBER (10) NOT NULL,
VESSEL_NAME VARCHAR2 (1000) NOT NULL,
CONSTRAINT PK_LINEUP_VOYAGE
PRIMARY KEY ( VOYAGEID ) ) ;
This is an excerpt of my .jdo file:
<class name="LineupVoyage" objectid-class="LineupVoyageId"
identity-type="datastore">
<extension vendor-name="kodo" key="table" value="LINEUP_VOYAGE"/>
<extension vendor-name="kodo" key="sequence"
value="LINEUP_VOYAGEID_SEQ"/>
<extension vendor-name="kodo" key="pk-column" value="VOYAGEID"/>
<extension vendor-name="kodo" key="lock-column" value="none"/>
<extension vendor-name="kodo" key="class-column" value="none"/>
<field name="vesselName">
<extension vendor-name="kodo" key="data-column"
value="VESSEL_NAME"/>
</field>

</class>
As you can see, the "id" field is commented.
And this is my class:
package br.com.fertimport.entity;
import java.util.*;
public class LineupVoyage {
 private String vesselName;
// private long id;
// public LineupVoyage(long id) { this.id = id; }
// public long getId() { return id; }
// public void setId(long id) { this.id = id; }
 public String getVesselName() { return vesselName; }
 public void setVesselName (String vesselName) { this.vesselName =
vesselName; }
The "id" attribute is commented.
Now the questions...
To use ClassSequenceFactory must the identity-type of my entities be
application or datastore?
Is the "objectid-class" parameter required in this case?
As you see, all references to the "id" property are commented. Can I
use this property to represent my object id?
If not, how can I identify my object with something like a long?
The last question is related to my architecture: one VM with the EJBs
(entity and session) and another VM with the web classes and JSPs,
connected by a session facade. I don't want to use any Kodo or JDO stuff
in the web tier. Is this possible?

How can i import procedure with %ROWTYPE in Oracle 10.2 (paris) warehouse b

Hello.
How can i import procedure with %ROWTYPE in Oracle 10.2 (paris) warehouse builder?Everytime i try to do it i get an error message:
API0411: Name should be an empty string.
If i comment out %rowtype i can import it without problems.
I have tried re-creating the procedure in OWB but once again i cannot find the %rowtype anywhere. the %type is there etc. I have tried to use Publish transformation / custom and cannot find %rowtypa there either.
Thank you very much for your help

Just in case you are having the same problem and cannot find any help anywhere - it is a bug in OWB.
I got in touch with Oracle Support and it appears that it is possible to import procedure/package with %ROWTYPE inside it, but it is not possible if the %ROWTYPE is in the arguments.
Just waiting for them to provide me with the bug ID.

How can I count time with labview7?

Hi
How can I count time with labview 7 and NI-DAQmx like I did with labview 6.1 and "count time-easy.vi" (count event or Time.vi).
I have a 6025E and labview 7.0
Thanks

I am not sure what you want to do or why..
... but here goes (some suggestions)
If you want to count the time between two events, you have a choice, you may use the Tick Count. Inisitalize it first by getting a timestamp and then do a difference within a loop. The difference will give you the time elapsed in ms.
You can also use the Get Date/Time String or Get Date / Time in seconds and once again take a snapshot when a first even occurs and another snapshot at the next even (at a point where you want to measure elasped time). This method is particularly useful if you want to timestamp an event.
If I didn't answer your question, can you elaborate what you mean by "How can I count time".
Best of luck..

My iTunes library is missing since upgrade Lion 7.2. I have it all backed up so that's not the issue. How can I reinstall it with all my hundreds of playlists intact or do I have to recreate each one upon reinstalling the backup copy? Thank you for help

Almost my iTunes library is missing since upgrade Lion 7.2. (the last 2.5 weeks worth of added music has transferred post-upgrade, none of whcih was bought from iTunes)
I have it all backed up so that's not the issue. How can I reinstall it with all my hundreds of playlists intact or do I have to recreate each playlist upon reinstalling the backup copy? This would save a HUGE amount of time and efforts. Thank you for your help!

hi Limnos,
I do not mean the entire ITunes folder but, rather, the contents of the ITunes folder prior to September 29th. (90% of the media is missing, along with all playlists) The media that remains says it was added on 9/29 although I know most of it was added many months or even years earlier. There are no playlists listed at all, before or after 9/29. (I know for certain that I added non-iTunes purchased songs on 10/6 although I had not created playlists for them)
I have my iTunes folder backed up on both an external drive as well as Time Machine.
I run iTunes off of an ITunes folder on my computer rather than from the external, if that's what you mean about how I have it set up.
Is it OK to drag the entire iTunes folder from the external drive onto my laptop's drive and see if that fixes it?
Thank you for your help!

How can I start anew with Photos and clear the (minimal) stuff it has uploaded

I've about had it up to here with this new Photos scheme. I reorganised my Aperture libraries on both my iMac and MBA in preparation for this, delayed turning Photos on for a couple of days until I thought everything was ready based upon the limited advice that was out there, and then got stuck in an endless loop of "uploading" and "preparing" every time I opened Photos. There are 19,975 images in my Aperture library on the iMac. I was stuck at Uploading at anywhere between that number and 19,000 with no progress after hours of waiting. I tried all the tricks mentioned here including re booting, restarting the app, repairing/rebuilding the database, killing the "cloudd" process, etc.today Today when I restarted Photos, it now said I had 23,775 images to upload- 4000
more than I have-and of course it got stuck there, like it has for the last week.
I copied the previous Aperture library (pre Photos migration)back to my iMac and opened it in Aperture. Thankfully, all the photos I had taken on my iPhone this week during this Photos clusterphuck transition were in the Aperture Stream so I didn't lose any of those. I'm willing to give this whole thing one more shot. So i need some advice. How can I start anew with Photos and clear the (minimal) stuff it has uploaded (about 6000 of 19,000 images in the last 7 days) ? If I simply delete the Photos.photolibrary file will that do the trick and lt me start a new fresh library using?

It is hard to say from your post, why the migration did not succeed in your case.
by "stuck on upload" do you mean, you opened the Aperture library in Photos, and Photos converted it to a Photo Library, and then the upload to iCloud Photo Library did hang? Or did already the upgrade to the Photo Library fail?
If you want the Aperture library to upload to iCloud Photo Library, it needs to be on a disk formatted MacOS Extended (Journaled) and the original image files must not be referenced. Referenced originals will not upload.
Also, the upload may hang, if you do not have enough free iCloud storage, orr if one of the videos or photos in your library is in an unsupported format or corrupted.
To start over, try to repair and rebuild the Aperture library before opening it in Photos. Try all Aperture Library First Aid options - starting with repairing the permissions. (Repairing and Rebuilding Your Aperture Library: Aperture 3 User Manual)
If I simply delete the Photos.photolibrary file will that do the trick and lt me start a new fresh library using?
You will have to delete the photos that are already in icloud too; otherwise you are risking duplicates.
Can you launch Photos at all? If yes, delete all photos in Photos and empty the Recently Deleted album. Wait for the deletion to sync to iCloud. Then delete the Photos.photolibrary.

How can I copy songs with metadata (added in iTunes) from my PC to my new iMac?

I have iTunes 12.0.1 on my Windows PC. I'm about to get a new iMac (hooray!) and I'm beginning the process of transferring everything on my PC to my Mac. I've got all the documents, pictures, files, etc. covered, but now I have to make a copy of all of my music.
Most of the music in my iTunes library is not bought through the iTunes Store (I download most of my songs from the Internet). Then, after saving the downloaded song to my computer, I go into iTunes on my computer and add the song. I also add metadata like artist, album, genre, album artwork, etc. to the song in iTunes. What concerns me is that only the songs in iTunes have this metadata: the original downloaded files I saved onto my computer don't have any metadata.
I really don't want to have to go through the long and tedious process of adding artist/album names, genre, etc. to every single song in my iTunes library on my new iMac. How can I copy songs with metadata (added in iTunes) from my PC to my new iMac?
Thank you so much for any help!

Hello! I'd like to learn more about Home Sharing. To do this, would both my PC (which I hope to get rid of) and my new iMac need to be plugged in?
Also, after Home Sharing with the old PC is initiated, I understand that all my songs would appear on my iMac. Is there a way to copy all of these (with album artwork, name, artist, etc.) directly to the iMac's hard drive and then disconnect home sharing so I can get rid of my PC?
Thank you!

Have you redeemed your iTunes card to an account associated with an Apple ID?
Once you have your iPad associated with an Apple ID AND you have an account with a credit card associated with the same Apple ID AND you have some 'store credit' (from redeeming your iTunes card) then purchases use the store credit before they charge the credit card, so you should be ok!
Personally, I use 'store credit' as a way to monitor whether or not there have been any 'unauthorised' purchases because as soon as the store credit is zero, the security code from the credit card is needed for further purchases! It does mean that I have sometimes to top up store credit before making a purchase, but 'better safe than sorry'!

HT2486 My address book only displays e-mails. How can I sync it with my i-phone to display the address book the same way as my contacts in my i-phone?

Currently my address book only displays e-mail addresses. It uses the portion of the address in front of the @ as the name. How can I sync it with my i-phone 4S that has name/numbers and addresses of my contacts?

Hello there, Seta.
You are correct that this can be done with iCloud. The following Knowledge Base article provides some great instruction for syncing contacts:
iOS: How to transfer or sync content to your computer
http://support.apple.com/kb/ht1296
Particularly:
Contacts, Calendars, Bookmarks, and Notes
You can sync contacts, calendars, bookmarks, and notes with other applications on your computer. This allows you to keep all your information in sync across multiple computers and iOS devices. The settings for these items are all in the Info tab for your iOS device in iTunes. With your iOS device connected to the computer, select your iOS device. Then click the Info tab.
For details on syncing content on your iOS device with your computer, click the sections below.
Contacts
To sync contacts with your computer, choose "Sync Contacts with" within iTunes for Windows, or "Sync Contacts" in OS X v10.8, or "Sync Address Book Contacts" in OS X v10.7 and earlier.
You can sync your contacts with:
Microsoft Outlook 2003, Microsoft Outlook 2007, Microsoft Outlook 2010 (Windows XP, Windows Vista, Windows 7, and Windows 8)
Windows Address Book (Windows XP)
Windows Contacts (Windows Vista, Windows 7, and Windows 8)
Address Book (Mac OS X v10.7 and earlier)
Contacts (Mac OS X v10.8)
Microsoft Entourage 2004, Microsoft Entourage 2008, or Microsoft Outlook 2011 for Mac
Notes:
When syncing contacts, you can choose to sync all of your contacts or only selected groups. The option to sync selected items may not show up until after the first sync.
You can select a group of contacts to which all new contacts created on your iOS device will be added.
Additional options for syncing include syncing your contacts with Yahoo or Gmail/Google Mail. You will need to configure it with the user name and password for your Yahoo or Google account.
Thanks for reaching out to Apple Support Communities.

How can i share documents with different users on the same mac?

How can i share documents with different users on the same mac?

Shared how? The other users can read the documents or you all can read and write the documents?
The first is easy just place the documents in /Users/Shared anyone can access the files there and the other users will be able to read them.
The second is a bit trickier.
