How to change the display in the waveform graph to enable higher frequency displays.

I am working with waveforms of very high frequencies upto 2MHz. When the frequency of the waveform is increased above 500Hz, the display in the waveform graph goes blank.
Please help me.
Thanks

Dear Labviewguru,
Thanks a lot for your response.
The problem had been technical, and it has been solved.
Actually, I didn't specify the number of samples while generating the waveform, so only frequencies upto half the default value (1000) were being displayed.
Regards,
Roopa

Thanks for any help you can provide.

LR on your laptop is still a desktop version. It is just now able to upload to the cloud to replicate photos to either http://lightroom.adobe.com/ or an iPad that has LR Mobile installed.
I think you probably just want to change the LR 5 identity plate back so it doesn’t mention LR Mobile all the time. Hover over the identity-plate area, and click on the little triangle that appears, then choose Change Identity Plate.

How to change a setting in the Java Control Panel with command line

Hi,
I am trying to figure out how to change a setting in the Java Control Panel with command line or with a script. I want to enable "Use SSL 2.0 compatible ClientHello format"
I can't seem to find any documentation on how to change settings in the Java Control Panel via the command line
Edited by: 897133 on Nov 14, 2011 7:15 AM

OK figured it out. This is for the next person seeking the same solution.
When you click on the Java Control Panel (found in the Control panel) in any version of Windows, it first looks for a System Wide Java Configuration (found here: C:\Windows\Sun\Java\Deployment). At this point you must be wondering why you don't have this folder (C:\Windows\Sun\Java\Deployment) or why its empty. Well, for an enterprise environment, you have to create it and place something in it - it doesn't exist by default. So you'll need a script (I used Autoit) to create the directory structure and place the the two files into it. The two files are "deployment.properties" and "deployment.config".
Example: When you click on the Java Control Panel it first checks to see if this directory exists (C:\Windows\Sun\Java\Deployment) and then checks if there is a "deployment.config". If there is one it opens it and reads it. If it doesn't exist, Java creates user settings found here C:\Users\USERNAME\AppData\LocalLow\Sun\Java\Deployment on Windows 7.
__deployment.config__
It should look like this inside:
*#deployment.config*
*#Mon Nov 14 13:06:38 AST 2011*
*# The First line below specifies if this config is mandatory which is simple enough*
*# The second line just tells Java where to the properties of your Java Configuration*
*# NOTE: These java settings will be applied to each user file and will overwrite existing ones*
deployment.system.config.mandatory=True
deployment.system.config=file\:C\:/WINDOWS/Sun/Java/Deployment/deployment.properties
If you look in C:\Users\USERNAME\AppData\LocalLow\Sun\Java\Deployment on Windows 7 for example you will find "deployment.properties". You can use this as your default example and add your settings to it.
How?
Easy. If you want to add *"Use SSL 2.0 compatible ClientHello format"*
Add this line:
deployment.security.SSLv2Hello=true
Maybe you want to disable Java update (which is a big problem for enterprises)
Add these lines:
deployment.javaws.autodownload=NEVER
deployment.javaws.autodownload.locked=
Below is a basic AutoIt script you could use (It compiles the files into the executable. When you compile the script the two Java files must be in the directory you specify in the FileInstall line, which can be anything you choose. It will also create your directory structure):
#NoTrayIcon
#RequireAdmin
#Region ;**** Directives created by AutoIt3Wrapper_GUI ****
#AutoIt3Wrapper_UseX64=n
#EndRegion ;**** Directives created by AutoIt3Wrapper_GUI ****
Func _JavaConfig()
     $ConfigFile_1 = @TempDir & "\deployment.properties"
     $ConfigFile_2 = @TempDir & "\deployment.config"
     FileInstall ("D:\My Documents\Autoit\Java config\deployment.properties", $ConfigFile_1)
FileInstall ("D:\My Documents\Autoit\Java config\deployment.config", $ConfigFile_2)
     FileCopy($ConfigFile_1, @WindowsDir & "\Sun\Java\Deployment\", 9)
     FileCopy($ConfigFile_2, @WindowsDir & "\Sun\Java\Deployment\", 9)
     Sleep(10000)
     FileDelete(@TempDir & "\deployment.properties")
     FileDelete(@TempDir & "\deployment.config")
EndFunc
_JavaConfig()
Now if you have SCUP and have setup Self Cert for your organization, you just need to create a SCUP update for JRE.

How to change a connection with the database in Runtime?

How to change a connection with the database in Runtime?
My connection was made using ADF Business component (ApplicationModule).
ADF Swing.
JDeveloper Studio 11.1.1.4.0.

When deploying ADF applications with database connection, you should be using JDBC data sources configured in the weblogic server.
You could change the JDBC data sources to a different DB instance or location - by changing the JDBC data source and restarting the weblogic server.

Looking up the values in a waveform graph with a mouse click

Hi,
Does anyone know how to look up the values in a waveform graph with a mouse
click but... without the cursor legend on, if i press in the waveform graph
nothing happens, i must search my cursors and only then i can see the values
of my signal data?! Isn't there any other way?
Best regards,
Thijs Boerée

Dear Chad,
I know of the function "bring cursor to center". I also figured out that
when i use a property node of the cursor array of clusters, that i can see
that some values change when i move the cursor (i can see the X and Y scale
value change of the graph and also the values of the mouse pointer (in
points due to screen resolution)) But in this cluster i can't set the mouse
position. I allready made a VI where i can see the bounds of my
waveformgraph and I have the Xscale (min and max) and the Yscale (min and
max), with a linear fit i can translate my mouse position to X an Y scale
values and when i click on my waveform graph the cursor go's to that
position (property node of the cursor position), only disadvantage is that i
only have the bounds of my plot area and not the position, i do have the
position of my waveform graph but the plot area isn't allways in the center,
if i could extract the position of the plot area i may find a solution to
solve this problem.
And to file a product question:
I would like to see the function that with a mouse click a little menu
appears and that there are options to for example set a marker on that data
and when you right click on it, that there are options to remove it or to
add comment, a 2D array could make a list of the different channels with
it's markers (time stamps and comments).
Best regards,
And thank you for your help.

How can I customize the scale of my waveform graph to suit my waveform?

I am trying to display a sinusoidal waveform on a waverform graph. I want to make sure that the graph displays only 5 cycles of the sine wave and thus changes the x-axis scale accordingly. Hence this would mean that me plot remains the same no matter what the frequency of sine wave I input, only the scale changes. How can I do this? Also once this is done, is there any way in which I can manually change the scale while labview is running to change to plot?

Here is an example that changes the scale of a graph. I think it is what you are looking for. Post back if it is not.

How to Change Date Format in the Title of the report.

Hi Everyone,
I want to change the Format of the Date in the title(Query run Date)taken by report through the variable "&Date" .
The Format available is DD-MON-YY
Desired Format is DD-MON-YYYY.
Please let me know the same as early as possible.

Hi NP,
What I try to do is to reformat the default &date inserted into the Title for Discovere Plus and Viewer. When you edit the Title for the report, you can select the date from the Insert dropdown list to display the date when the report was run. The Date (shown &Date in the Title) has a default format of DD-MON-YY. As I have other date parameters displyed in the Title that have the format of DD-MON-YYYY specified by the user, I want to have the &Data in the same format. Please advise me how to achieve this.
Thank yiou very much,

Selman wrote a Java3d book that was well received
and has a Swingtest.java applet and application that
allows you to load objects dynamically,
ie. "change" the viewed object when it is running by
allowing the user to select "sphere" or "cube" from
menu lists ( in this case it's not just displaying
Jav3d primative objects, but it has the core functionality
of deleteing and adding nodes in the scene graph that you
are seeking, and at that point the rest is left as
exercise to the student. The ObjLoad.java in Sun's Demos
directory has the code to load ".obj" files, so you have
all the tools you need.

The Prentice-Hall books by Aaron Walsh are false & fraudulent
in their claims to present the most current methods, as a part
of the "Couch-Beiter Flame War" and fraud involving Sandy Ressler
at the NIST. Prentice-Hall, Yumetech.com and Aaron Walsh have
misrepresented and disparaged the old & reliable Sun VRML Loaders
in favor of the "new" Yumetech.com Loader, and the web demo above
__ DOES NOT __ load Web3d.org's __ VRML __ files, only the less
capable ".obj" files ... so the "Web3d" series of books from Prentice-Hall
does not show the loading of ___ Web3d.org 's ___ VRML __ files
because Sun's VRML Loaders were the best ones, and the Yumetech.com
folks didn't want anyone using those, and started the "Couch-Beitler Flame War"
to disparage, falsely & fraudulently misrepresent the facts and knowingly
published false and misleading "disinformation" in the
unreliable Prentice-Hall / Pearson Ed books, harming our community.
The Sun VRML Loaders are used by __ Nasa, __
the NSF supported Virtual Chemistry Lab ( "Lab3d" ),
me, and others simply choosing the "what works best",
and by people using Sun's Java3d FlyThrough & Java Scenegraph Editor.

I misunderstood the original question ( it was too terse ).
I interpreted the question has how to change the loaded
objects --- between successive runs of the program ---
and not as you intended -- dynamicall while running
the program program without quiting & restarting.
In a "Java3d" forum I'm not going to wander into
how basic ( non-Java3d) 2d commonents such as TextFields
are programmed.
The original Vrml97Player.java file that came with
Sun VRML Loaders also implemented the functionality
of loading mulitiple files ( sequentically during one run )
and I have worked with that and similar things with
the Shout3d.com engine and my own 3d Java engines.

How to change page type after the fact

In the application builder, I click on an application and choose Details in View.
I get the list of pages I have in my app.
The page type column has:
Interactive Report
Navigation Form
Dynamic HTML
DML Form
Chart
Report
How do I change this column after a page has long been created?
Specifically, I want to the change "Dynamic HTML" to something else.
Why?
Because on this particular page, tabs do not work (error: page not found).
Buttons created among a regions items do not work (same error, page not found).
I need to use tab and buttons to go from this page to other pages.
And I am suspecting the page type may have something to do with my problem.
Thanks in advance for any pointers.

Thanks for your consideration!
For my current app, a clinical management system,
I'd like to have, say, 1000 items.
(For other applications I am thinking about, but have no time,
nor expertise for now, I'd need millions of items,
each corresponding to a pixel of a graphic.)
Who cares if the current computers are too slow?
How about make it a parameter that can be changed
per app or per apex installation, and default to 100?
Some forms can be broken up logically, as people have helpfully suggested,
and I did follow that advise on some pages.
But other forms cannot be. People have put a lot of thought on designing
those forms, they are government or legal standards (or at least something more important
than computer performance), and people have been trained
with those original forms.
Consider the hoops I have to jump through to get more than 100 items
on a page I am currently working on:
Generate the items (INPUT type="text" and INPUT type="checkbox") using PLSQL
lots of htp.p('<INPUT ...>').
a JavaScript function to collect all the values on the page
and make up an XML string. submits this string to an application
process, and application process parses the XML string and does insert or update.
Another JavaScript to populate the items based on the current values of a row,
using an application process to retrieve the columns of a row.
There are about 150 items on this particular page.
All these are ok, because I was aware of the restriction of 100.
And because I wanted to generate my own HTML to mimic the original
form anyway.
Then things started to go weird.
I need buttons to go back to another page. and I use tabs.
Buttons to go back from this page,
when a button is created with "Create a button in a region position",
it works fine.
When a button is created with "Create a button displayed among this region's items",
it does not work, and I get HTTP 404, https://.../apex/wwv_flow.accept, page cannot be found.
But I need a button to work like the one created with "Create a button in a region position",
but displayed like the one created with "Create a button displayed among this region's items".
This is still not too bad. I saw the difference between the two kinds of buttons.
I copied the HTML code for the button "Create a button in a region position",
and used a display only item to create a Back button where I wanted:
'<table class="t15Button" cellspacing="0" cellpadding="0" border="0"><tr><td class="t15L"><img src="/i/themes/theme_15/button-l.gif"/></td>'||
'<td class="t15C">Back</td>'||
'<td class="t15R"><img src="/i/themes/theme_15/button-r.gif"/></td></tr></table>'
Here P145_BACK holds the page number to which I want this page to go back to.
Then I noticed that the tabs did not work any more. same error, page not found.
That's is when I got a little frustrated and posted for help on the forum.
Then I begin to undo my steps, and
by lucky accident, I noticed that, if none of the checkboxes is checked,
the tabs work fine. If at least one is checked, I get this error, page not found.
My current solution is to add a function of my own in the doSubmit(B) function in file apex_3_1.js,
which unchecks all checkboxes (o.checked=false).
And now, from this page of about 150 items,
the tabs are ok, and I have a button that is similar to one
created with "Create a button displayed among this region's items", except I created myself
using HTML.
I think this trick of using a custom function in doSubmit(), that unchecks or even hides
INPUT type="text" items (o_div.style.visibility = "hidden"; o_div.style.display = "none";)
should work in general. this function is only invoked when the user clicks the tab,
or buttons among a region's items.
Somebody said regarding restrictions on drugs or sex.....
you will not make people stop, you just make it harder or more expensive.
Same here and many other things, a restriction is just making things harder.
People will try to get around it.
Now that I have a solution, and I am aware of the problem, I'll calm down and
go back to my own thing for now.

How to change tempo without affecting the music (only the grid)

This is a very basic problem. I have been laying songs (audio files) onto logic and recording vocals over them, and now that I am finished with the recording, i realize that in order to copy and paste the choruses EXACTLY throughout the songs, which can be quite arduous the way I have been trying to do it, one needs to have matched the proper tempo with the the music being used.
I neglected to do this at the start of these projects, and it has come back to bite me because when I try to change the tempo now, it completely throws my vocals out of whack because my voice is off beat. This is where the problem lies. I know had I addressed this at the beginning, I would be smooth sailing.
I also tried setting the tempo at the proper rate on a new logic project, but when I drag everything over from the original project, the same problem occurs.
In reality, I need the grid to match up so I have the proper means to line up my vocals exactly so the choruses are consistent throughout the song (obviously I can do it manually in a way regular listeners might not notice, but Im dissatisfied with that, I want it to be perfect)
Again, I know that if I had matched the tempo properly with the audio file (the music) at the beginning, there would be no problems, and I'd be able to record over it and then use the bars to align my vocals perfectly.
If some one would be so kind as to get back to me on this, it would be highly appreciated

You're close!
1• Open the automation event list on a track that contains automation. You will now see what looks like a normal event list but it's displaying only the automation data on that track
2• Click the hierarchy arrow to take you "up a level" so that the automation event list (AEL) now shows you the names of all of the automation regions within the (hidden) automation arrange page. What you'll see is a list of items all starting at bar 1 1 1 1 called "Automation". (If the position of the items is not 1 1 1 1, you have a problem. See below).
3• Select All (CMD-A) and then use whatever method you prefer to SMPTE-lock them (menu item or key command)
= OR =
Do Step #1. Then hit CMD-1 to open a new Arrange window. When you do this right after opening an AEL you will see the automation arrange page. Move the AEL out of the way or simply close it. Then, similar to Step #3, select all of the automation regions in the automation arrange page (CMD-A) and SMPTE-lock them.
Note: if your automation events are not all starting at 1 1 1 1 then it's an indication that your song's start marker was moved to before bar 1 and you're on your way to having a corrupted song.
Final caveat: don't attempt to write new automation while the old automation data is SMPTE-locked. It'll create a nice lil' mess. So after you're done changing the tempo (or whatever your reason for SMPTE-locking regions and automation), the first thing you should do is unlock them both before proceeding with any additional recordings. It's very easy to forget that the automation data is locked because you can't see that it's in a locked state unless you're looking at the AEL or the automation arrange page.

How to get the data from a waveform graph?

Hellow!
I have a waveform graph which has the experiment signal, so how can i do to save the X,Y data in a file?
thanks!
Mike

Hii,
You can store the data as shown in the vi, just use the signal data by converting it into the numeric form and give it instead of random data.
Hope this will help.

How to change Font Type of the Title Text of a JFrame?

Hi,
I want to set a different Font Type for the Title text of the titlebar of my JFrame.
Is it possible? Can anyone show me how if it is?
Thanks.
Niteen

Michael,
Thanks. It works!
But there was a problem. I was not using the :-
JFrame.setDefaultLookAndFeelDecorated(true);
so I have to use it now.
Is it possible to do it without the default decorated look and feel? Because the default LNF title bar has too much height and I am cramped for space.
I know that's no excuse. I tried but it doesn't work.. I am using a extended JFrame like this:-
class Testing extends JFrame
public Testing()
setSize(300,100);
setLocation(400,200);
Container container = getContentPane();
/* add components to this container here */
setVisible(true);
When I use getComponent() for the container, I get an ArrayIndexOutOfBound Exception.
When I set the argument to getComponent(0), the font in the title bar is not changed.
What else should I do?
Thanks.
Niteen.

How to change Apple Id for the cloud

Currently my Apple ID is an email address which I have been using for decades. In the near future the email server will be decommissioned and I will no longer be able to use it. In preparation of the change over I want to change my current email address to an icloud email address (@icloud.com). I have gone into the site to Manage Apple ID to change the email address but it won't let me as I get an error message that Apple ID must not use a domain owned by Apple. How can I change my Apple ID and Primary eMail Address to an @cloud.com account without losing all the info already on my current icloud?

First save any photo stream photos that you want to keep on your device by opening the photo stream album, tapping Edit, tap the photos, tap Share, tap Save to Camera Roll. If you are syncing Notes with iCloud, email them to yourself as you will have to recreate these after changing accounts. Finally, if you are syncing any iWork documents with iCloud go to the settings for these apps and turn iCloud sycing to Off.
Then go to Settings>iCloud, tap Delete Account, choose Keep on My iPad when prompted. (This will only delete the account from your device, not from iCloud. If your daughter is keeping the existing account her devices will not be effected by this.) Then sign back in with your new ID to create a new iCloud account, turn on your iCloud data syncing, choose Merge when prompted to upload the data to the new account. Then recreate any Notes from the emails sent earlier and turn on iCloud syncing with iWork again, if appropriate.
existing iCloud old email address with the old account. If you still want to access it on your iPad, you'll have to go to Settings>Mail,Contacts,Calendars>Add Account>iCloud and sign in with the old account ID. This email will be fetch only, not push.
Once your iPad has migrated to the new account, if you also want to move your Mac to this account go to System Preferences>iCloud, sign out, then sign in with the new ID.

How to change apple account in the ipad many times?(can't sign out)

How to change accounts!
I have multiple accounts not me but the whole family has apple accounts since we all are apples. Anyway everyone has a no credit card account except my dad. His account is synced in my sisters iPad. My dad changed the password so that we don't buy stuff the problem is we can't sign out of our dads account! I mean when we go to ipad:setting->store we already see that its already signed in my sisters account! But the problem is whenever my sister wants to update or download a free app it gives my dads email & wants us to fill the password! We already signed out!
We tried logging in via itunes store then syncing the ipad but nothing happened!
The apple retail store said after you submit the email of your ipad the only solution is to format it. But here is the big problem lets say we formatted it & after few days/months etc we wanted to buy an app we couldn't change the account to our dads account! Since we already are having trouble logging out of our dads account.
So please tell me how to change the account many times! Because I couldn't change it in the iPad nor in iTunes in my iMAC.

The apple retail store said after you submit the email of your ipad the only solution is to format it
Your iPad does not have an email address.
You will need to add a CC card to verify your account. The CC info can then be removed and the account used normally.
It would likely be easier to simply update the apps on the computer then sync the iPad.
iTunes can be authorized for all accounts then all apps can be updated at once.

How to change what search engine the adress bar uses when typing in a search to something that isn't Google

I currently left all Google services I used, Gmail, Chrome, etc.. because of the recent selling info to the gov and what not and although it may or may not be true I am being safe and switched to Firefox and a different email provider. Anyway so far I like Firefox I am using DuckDuckGo as my current default search and I would like to use it as my search engine when I type in a search in the address bar, by default it's Google how do I change it to a search provider I want to like DuckDuckGo?

Hello,
If you have installed DuckDuckGo on Firefox, you can follow these steps:
# Type '''about:config''' in the address bar.
# A warning appears, click "I'll be careful, I promise!"
# Type '''browser.search.defaultEngine''' in the search box at the top of the page.
# Double-click the item that appears.
# Set the value to '''DuckDuckGo''' or whatever search engine that you would like to use (case sensitive I think).
(I have attached a screenshot).
