How to search a special string in txt file and return it's position in txt file?
How to search a special string in txt file and return it's position in txt file?
I just posted a solution for a similar question here: http://forums.ni.com/ni/board/message?board.id=170&view=by_date_ascending&message.id=362699#M362699
The top portion can search for the location of a string, while the bottom portion is to locate the position of a character. Both can search for a character.
The position of the character within the file is displayed in the indicator(s).

Searching for a string in an excel file and return true if found.
How can I search for a string in an excel file and return true if found, its location and also a value.
The problem with searching an excel file is that it contains a header. It would be easiest if you just read the file into a LabVIEW array and search the array. This way you can also get the index and the value of the location.

How to use multiple VCI strings for lap 1300 and 1200 (option 60) in one pool?
Hi All,
Hope to you a very happy new year,
I have two differnt LAP 1300 and 1200 in my network and I need to add theme to the WLC,
I successed to add one of theme by the option 60 in the DHCP pool at the Core SW,
So my quetion is below:
How to use multiple VCI strings for lap 1300 and 1200 (option 60) in one pool?
Thanks in Advanced,
Ahmed,To add to Scott's post. Option 60 would be useful if you needed to put certain types of AP on specific controllers. Otherwise, no real need to use it for the most part.
Though, I do recall an issue a few years ago that some windows machines had issues getting DHCP if option 43 is being returned.
Now, on an IOS switch, you can only configure one option 60 per DHCP scope

How to search for particular string in array?
I am struggling to figure out how to search array contents for a string and then delete the entry from the array if it is found.
The code for a program that allows the user to enter up to 20 inventory items (tools) is posted below; I apologize in advance for it as I am also not having much success grasping the concept of OOP and I am certain it is does not conform although it all compiles.
Anyway, if you can provide some assistance as to how to go about searching the array I would be most grateful. Many thanks in advance..

Is that right?
Can you use an ArrayList<String> instead of a String[ ]?
To find it, you would just do:
for (String item : myArray){
if (item.equals(searchString){
// remove the element. Not trivial for arrays, very easy for ArrayList
}Heck, with an arraylist you might be able to do the following:
arrayList.remove(arrayList.indexOf(searchString));[edit]
the above assumes you are using 1.5
uses generics and for each loop
[edit2]
and kinda won't work it you have to use an array since you will need the array index to be able to remove it. See the previous post for that, then set the value in that array index to null.

How does "Unflatten From String" take a type and return a value of that type?
http://zone.ni.com/reference/en-XX/help/371361E-01/glang/unflatten_from_string/
How exactly does the "type" argument for "Unflatten From String" work? I need to create a VI that takes a type, passes it as an argument to several calls of the "Unflatten From String" function, and returns an array containing elements of the type originally passed. The "Unflatten From String" function seems to do some magic though, because the type of the "value" that it outputs changes depending on the type it is passed as input. How do I do the same magic in my VI?
Ultimately, what I need to accomplish is an unflatten-list operation. Given a type T and a byte string of length L (which contains a concatenation of T elements that are flattened to their bytes), create a VI that unflattens all the types in the string and return an array of length (L / sizeof(T)) that contains each type.
Note: performing the unflatten-list operation is trivial, but I cannot for the life of me figure out how to do it in a VI that takes a type and returns an array of the appropriate type. By the way, my data is being given to me from another source, so please don't bother suggesting that I should be flattening an array using LabVIEW's "Flatten To String" function in the first place. My data is not given in LabVIEW's array format: http://zone.ni.com/reference/en-XX/help/371361B-01/lvconcepts/flattened_data/
Thanks a ton!
-WakkaTake a look at this example: You can see that the flattened string contains several bytes. The first four bytes contain the length of array (number of elements). Since the data type is U32, the next 32 bits (4 bytes) contains the value of the first element, and so on. Could you possibly use this scheme to do what you want to do? Other data types present different outputs. You would have to experiment with them.

How to know that a method has been called and returning value of a method
Hi, everyone! I have two questions. One is about making judgment about whether a method has been called or not; another one is about how to return "String value+newline character+String value" with a return statement.
Here are the two original problems that I tried to solve.
Write a class definition of a class named 'Value' with the following:
a boolean instance variable named 'modified', initialized to false
an integer instance variable named 'val'
a constructor accepting a single paramter whose value is assigned to the instance variable 'val'
a method 'getVal' that returns the current value of the instance variable 'val'
a method 'setVal' that accepts a single parameter, assigns its value to 'val', and sets the 'modified' instance variable to true, and
a boolean method, 'wasModified' that returns true if setVal was ever called.
And I wrote my code this way:
public class Value
boolean modified=false;
int val;
public Value(int x)
{val=x;}
public int getVal()
{return val;}
public void setVal(int y)
val = y;
modified = true;
public boolean wasModified()
if(val==y&&modified==true)
return true;
}I tried to let the "wasModified" method know that the "setVal" has been called by writing:
if(val==y&&modified==true)
or
if(x.setVal(y))
I supposed that only when the "setVal" is called, the "modified" variable will be true(it's false by default) and val=y, don't either of this two conditions can prove that the method "setVal" has been called?
I also have some questions about the feedback I got
class Value is public, should be declared in a file named Value.java
public class Value
cannot find symbol
symbol : variable y
location: class Value
if(val==y&&modified==true)
*^*
*2 errors*
I gave the class a name Value, doesn't that mean the class has been declared in a file named Value.java*?
I have declared the variable y, why the compiler cann't find it? is it because y has been out of scale?
The other problem is:
Write a class named Book containing:
Two instance variables named title and author of type String.
A constructor that accepts two String parameters. The value of the first is used to initialize the value of title and the value of the second is used to initialize author .
A method named toString that accepts no parameters. toString returns a String consisting of the value of title , followed by a newline character, followed by the value of author .
And this is my response:
public class Book
String title;
String author;
public Book(String x, String y)
{ title=x; author=y; }
public String toString()
{return title;
return author;
}I want to know that is it ok to have two return statements in a single method? Because when I add the return author; to the method toString, the compiler returns a complain which says it's an unreachable statement.
Thank you very much!Lets take this slow and easy. First of all, you need to learn how to format your code for readability. Read and take to heart
{color:0000ff}http://java.sun.com/docs/codeconv/html/CodeConvTOC.doc.html{color}
Now as to your first exercise, most of it is OK but not this: public boolean wasModified()
if (val == y && modified == true)
return true;
y being a parmeter to the setValue method exists only within the scope of that method. And why would you want to test that anyways? If modified evaluates to true, that's all you need to know that the value has been modified. So you could have public boolean wasModified()
if (modified == true)
return true;
}But even that is unnecessarily verbose, as the if condition evaluates to true, and the same is returned. So in the final analysis, all you need is public boolean wasModified()
return modified;
}And a public class has to be declared in a file named for the class, yes.
As for your second assignment, NO you cannot "return" two variables fom a method. return means just that: when the return statement is encountered, control returns to the calling routine. That's why the compiler is complaining that the statement following the (first) return statement is unreachable.
Do you know how to string Strings together? (it's called concatenation.) And how to represent a newline in a String literal?

How to get video file and iTunes Extra to show as one file in iTunes?
When I purchase a movie in iTunes with iTunes Extras, after the download is finished in the "Movies" and "Genres" view they appear as one file. You click on the cover, it opens, shows the "Play iTunes Extra" button as well as a small Play arrow button next to the title to play the movie directly. Only in "List" view do they appear as separate files.
How can I achieve that for my own iTunes extra? I tried giving the .ite the same XID as the movie file but that didn't work, they continue to appear as separate files in iTunes and the little play button when expanding the iTunes Extra doesn't work obviously. Anyone can tell me how this is done?Ok, I finally figured it out... there is 2 files that play a critical role in this
first is manifest.xml
in this file ensure that the library_item type string references the xid for your video file, and it has to be a proper xid. The iAd Producer manual explains how to create one if it does
example:
<library_item type="video" local_id="feature" xid="TEST:uuid:C7AE7CED-3F60-4C08-AA01-E3F9647B95CC" name="Your Movie"/>
second file and even more critical is iTunesMetadata.plist. There is a couple of strings in there that lace the iTunes Extra to the film and vice versa
<key>itemId</key>
<integer>987654321</integer>
<key>itemName</key>
<string>Your Movie - iTunes Extras</string>
The first is a unique 9 digit number that identifies your iTunes Extra file, the second is the name of the file that should follow the convention "Your Movie Title - iTunes Extras"
<key>playlistId</key>
<integer>123456789</integer>
<key>playlistName</key>
<string>Your Movie</string>
This is what ties it back to the movie file, we will come back to it later where in the movie MetaData you need to place this 9 digit string
<key>xid</key>
<string>TEST:uuid:C7AE7CED-3F60-4C08-AA01-E3F9647B95CC_ITUNES_EXTRAS</string>
This is the convention in how to properly xid your iTunes Extra, it is your movie's XID with "_ITUNES_EXTRAS" added to the end of it
<key>Name File</key>
<string>Your Movie - iTunes Extras.ite</string>
<key>associated-adam-ids</key>
<array>
<integer>123456789</integer>
The first is self explanatory but the second is again this 9 digit number that you will need to place into the meta data of your movie. It is what will make iTunes lace the two files together
<key>xid-asset-mapping</key>
<dict>
<key>TEST:uuid:C7AE7CED-3F60-4C08-AA01-E3F9647B95CC</key>
<array>
<integer>123456789</integer>
</array>
<key>TEST:uuid:C7AE7CED-3F60-4C08-AA01-E3F9647B95CC_ITUNES_EXTRAS</key>
<array>
<integer>987654321</integer>
</array>
</dict>
This is the last critical piece, it laces the two files tigthly together. Now the 9 digit number counting down from 9 is part of the unique ID of the iTunes Extra, the 9 digit number counting up from 1 needs to be put into the metadata of your movie. The annotation type for this is "contentID".
That's pretty much it. If you did it right your files will now appear as one file in cover view just like a movie bought in the store.
The easiest to do this right is to grab the manifest.xml and iTunesMetadata.plist from an iTunes store movie and copy paste and edit it for your purposes, which is what I did.

I have a Macbook Pro with OS X Lion 10.7.2. I have sent a work file to the trash bin along with many other files. When I empty the trash this one particular file remains and I get a message that this file is still in use. I have tried returning the file to my documents, opening it, closing it and then sending it to trash and again I try to empty trash but the same message comes up - Q - How can I trash this file permanently?
First just try logging out and back in. Whatever is holding on to it may not be running after the logout thus freeing it so you can trash it after logging back in.
You might also try Trash It!
Lastly, look at the following for suggestions:

With Dropbox, I right click on a file within my designated Dropbox folder and choose share Dropbox link. This copies a unique URL that I can send to anyone to then download that file and that file only. I do not have to add people to my access list to allow the download.
How do I do this with Oracle Documents? I have one off large files that I prefer not to send via email, however, I do not want to add everybody in the company as a member to my access list.There is an option called Public Links which allows you to do this. Select your item and click Share. This throws a pop-up dialog. On the left side of the dialog you may have 3 options - Members, Member Links, Public Links. If the Public Links option is not there, then your service administrator has disallowed them from use. The Public Links option is a controversial one in the enterprise space. DropBox's original offering had no qualms with offering public links because the content was guaranteed to be the property of the dropbox user. However, at enterprise level, the content belongs to the owning enterprise, so service administrators may elect not to allow this feature. This is down to your organisation.
If you see the Public Links option, click on it and the right side of the popup dialog will change. You can specify:
a name for each link you create (so you can keep track of which link is which),
Link Permissions, only the following are available for obvious reasons - Viewer, Downloader, Contributor
Link Expiration Date - a date after which the link will not work
Access Code - a pass code which you can divulge to expected recipients by alternative means of your own choosing. This access code guarantees a measure of security on a link which could otherwise be used by anybody
You can create several public links for the same item, and each of those can have the above settings, so you could have one link for downloaders and a separate link for contributors, for example. Each link can then be sent, either by copy/paste or through the email button to the right of the link. You can also modify the link using the pen icon, so you can unexpire it or reset its expiry date. You can also delete a link using the trash button next to it.
I hope this explains the public link feature.
Regards,
Frank.
