Making customisation from the default profile is generally considered poor practice and quite often doesn't work out as planned. (If you're interested in some more information on this, [http://mockbox.net/windows-7/227-customise-windows-7-default-profile.html see here] see here)
This article should help you with developing and deploying your customised Firefox 4 installation (without touching the Windows 7 default user profile):

Your problem is that you need to have a
<sql:setDataSource
       var="myDataSource"
       dataSource="jdbc:mysql://localhost/user,com.mysql.jdbc.Driver,user,parul"
/>and your sql:query would now be
<sql:query var="login" dataSource="${myDataSource}">
SELECT * FROM login;
</sql:query>You can use whatever name you want for the var in the setDataSource as long as it matches the dataSource in the query.

I write digital port by 'DAQmx Configure Logging.vi' and receive TDMS file with 8 boolean channels. How can I write to 1 integer channel?

Hello!
I want to write 1 digital port from PXI-6536 with streaming to TDMS file.
I'm writing by 'DAQmx Configure Logging.vi' and become TDMS file with 8 boolean channels.
How can I write to 1integer channel?

Hey Atrina,
The actual data stored on disk is just the raw data (that is, a byte per sample in your case). It's really just a matter of how that data is being represented in LabVIEW whenever you read back the TDMS file.
I'm not sure if there is a better way to do this, but here is a way to accomplish what you're wanting:
Read back the TDMS file as a digital waveform. Then there's a conversion function in LabVIEW called DWDT Digital to Binary. This function will convert that set of digital channels into the "port format" that you're wanting. I've attached an example of what I mean.
Note: When looking at this VI, there are a few things that the downgrade process did to the VI that I would not recommend for these TDMS files. It added a 1.0 constant on the TDMS Open function, and it set "disable buffering" on the TDMS Open function to false; you can get rid of both of those constants.

How can I write new objects to the existing file with already written objec

Hi,
I've got a problem in my app.
Namely, my app stores data as objects written to the files. Everything is OK, when I write some data (objects of a class defined by me) to the file (by using writeObject method from ObjectOutputStream) and then I'm reading it sequencially by the corresponding readObject method (from ObjectInputStream).
Problems start when I add new objects to the already existing file (to the end of this file). Then, when I'm trying to read newly written data, I get an exception:
java.io.StreamCorruptedException
at java.io.ObjectInputStream.readObject0(Unknown Source)
at java.io.ObjectInputStream.readObject(Unknown Source)
Is there any method to avoid corrupting the stream? Maybe it is a silly problem, but I really can't cope with it! How can I write new objects to the existing file with already written objects?
If anyone of you know something about this issue, please help!
Jai

Here is a piece of sample codes. You can save the bytes read from the object by invoking save(byte[] b), and load the last inserted object by invoking load.

Having Oracle 9i.
One more doubt. In the speck, some constand values are there, When i write the same into file, How can i write ?.
1. l_str := ' "E27" '
or
2. l_str := ' E27 '
UTL_FILE.PUT_LINE(L_FILE_POI,l_str,TRUE);
1 case : in XML file : "E27"
In 2 case : E27
When we write a XML file through editors , we have to define the constant within quote . is it?
Which one can i use ? Or any other way is there ..

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.
Cheers,
Pedro.

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.

How can I write a program that compiles without warnings?

I tried the following with the 1.5 beta-compiler (build 28; I think):
class Y {
     public static final class Pair<X,Y> {
       private X fst;
       private Y snd;
       public Pair(X fst, Y snd) {this.fst=fst; this.snd=snd;}
       public X getFirst() { return fst; }
       public Y getSecond() { return snd; }
       public String toString() { return "("+fst+","+snd+")"; }
public static void main(String... args) {
     Pair[] pairArr = new Pair[10];              // supposed to be an array of Pair<Integer,Integer>
     for (int i=0; i<pairArr.length; i++)
         pairArr[i] = new Pair<Integer,Integer>(i,i);
     for (int i=0; i<pairArr.length; i++) {
         Pair<Integer,Integer> p = pairArr; // unchecked warning
     System.out.println(p);
     Integer first = p.getFirst();
     Integer second = p.getSecond();
// ... more stuff ...
It turns out that I get an unchecked warning when I extract an element from the array of pairs. Okay, that's fine. How can I avoid the warning? I had expected that an explicit cast would help.
Pair<Integer,Integer> p = (Pair<Integer,Integer> )pairArr;
With a cast I'm telling the compiler: "I _know_ what I'm doing; please trust me." But the compiler still issues a warning.
How can I write a warning-free program in this case? The only thing I can think of, is not using the parameterized type Pair in its parameterized form. But it's not the idea of Java Generics that I refrain from using parameterized types. What am I missing?

It turns out that I get an unchecked warning when I
extract an element from the array of pairs. Okay,
that's fine. How can I avoid the warning? I had
expected that an explicit cast would help.
Pair<Integer,Integer> p = (Pair<Integer,Integer>
)pairArr;
With a cast I'm telling the compiler: "I _know_ what
I'm doing; please trust me." But the compiler still
issues a warning. Yes, but at least you were able to change the warning from "unchecked assignment" to "unchecked cast" which is a little shorter ;-)
Seriously , since arrays of generic types are disallowed, there is probably no way to get rid of these warnings - which makes a strong point for eliminating "unchecked" warnings altogether (see the other thread "selectively suppressing compiler warnings")

How can I Write a sine wave in an Access-file?

I measure a sine wave in LabView 6i. How can I write the datas automatically to an Acces-file, at the same time?
In my program, I managed it with Execute SQL.vi, I change a number in a SQL statement(String) -> after this I push start and then it writes the statement in the Access-file.
The problem is, it writes only one data per measurement in the file. How can I write all datas in the Access-file and measure the wave at the same time?
Thanks for help!

getwave.vi ‏49 KB

On the waveform palette, you will find a "to components" vi that you can break out the array of the waveform. You can then, using a for loop write all of the values from the waveform.
Better yet, there are examples in the database toolkit manual on pages 3-13 to 3-15 that deal with reading arrays (and even has a waveform example).
Good luck!

Drive Partition and Format
1.Open Disk Utility in your Utilities folder.
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. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Click on the Options button, set the partition scheme to GUID then click on the OK button. Set the format type to Mac OS Extended (Journaled.) Click on the Partition button and wait until the process has completed.
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.) Click on the Security 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 can take up to several hours depending upon the drive size.
Steps 4-6 are optional but should be used on a drive that has never been formatted before, if the format type is not Mac OS Extended, if the partition scheme has been changed, or if a different operating system (not OS X) has been installed on the drive.

How can I write to an OPC Server?

Hello!
I was busy a few days with LabVIEW 8 to finish a special task, but now I've got problems to solve the following problem:
I have an OPC connection between a frequency converter and LabVIEW 8. With the example vi's I get the data out of the OPC Server (revolutions per minute).
So I can read data out of the OPC Server, but how can I write? I want to write several voltage values to the OPC Server that the frequency converter gets the required revolutions per minute.
Have you got any ideas? Are there existing example vi's to write data to an OPC Server?
Best regards and Thanks in advance!

So here it is - a little bit modified, but you should get the idea out of it.
If you have questions, I'll try to answer them .
