Is it possible to make a line of a multicolumn listbox active?

I currently have data entered into multicolumn listbox. While the program is running, is it possible for a row of the listbox to be selected and then give the index number of that row? From there I will want to use that index number to reference other arrays, but right now I'm just dealing with getting the index number I need from the user's row selection.

The I32 is the default numeric constant, I didn't see the need to change it for this purpose.
You missed my point. The output datatype of the Value property node is an I32. You are wiring to an I32 indicator, but shoving it through a TypeCast function. This is pointless.

Adding a single line to a multicolumn listbox?

Hi Community,
I have a multicolumn listbox which tens of thousands of lines where each line is color coded and represent a cycle with a pass/fail status. The only way I have found to add lines to a multicolumn listbox is to read its ItemNames property which is a 2D array of strings, add the new line to the 2D array and then write then new array back to the ItemNames property.
The problem is that after couple thousands of lines this get more and more slow.
Is there any way to speed this process up, maybe by adding the line to the listbox in a different way?
thx.

The Listbox, and Multicolumn listbox controls got many UI performance improvements in 2013, what version are you using?
https://lavag.org/topic/17009-labview-2013-favorite-features-and-improvements/
But even if you are on an old version there are many tricks to making the UI more responsive, like using defer panel updates, and virtual multicolumn listboxes.

Is it possible to make a line/rectangle movieclip on stage flexible?

I would like to take a straight line/rectangle that is already created on stage and tween it with as3 so that when mouse is down, i can drag and bend it into an ark shape, and when i release the shape snaps back to its originally form? Tutorials on the tween class would be appreciated.

This file doesn't actually use tweens, but it will show you how to bend a line using the graphics arc class. You can create a rectangle by drawing four of these lines. http://www.ddg-designs.com/downloads/pushLine.zip

Is it possible to make a simple y vs x line graph, when neither of the two data series is in a header?

For hours I have been trying to do this, without success. When there are two columbs of numbers, in the bidy of a table (the sheet), there seems to be no way to make a line plot one column vs the other, as is easy to do in Excel. A scatter plot seems to work, but not a line plot.
Weird!
Can someone tell me if a line plot is possible?
Thanks so much.

It is simple to do what you want. It is two extra steps as compared to doing it the "Numbers" way with the X data and the series names in headers. Note that a line plot is not a true X-Y plot of X vs Y unless your X data is evenly spaced and in numerical order.
1. Select the Y data and make a line chart
2. With the chart selected, go to the Axis tab of the Format sidebar, click on the "Category X" button, and replace the "Label References" with references to your X data. In my example I changed it to Table 1::D6:D8 and it expanded it out into separate cell references.
3. Click on the Series tab and change the "name" reference to point to your series name in the chart. In my example I changed it to Table 1::E5

How to make new line in JButton.setText()?

how to make new line in JButton.setText()?
I want to set the text of jbutton in tow line ,as follows
| jbutton-line1 |
| xxxxxxx-line2 |
i konw i can jbtton.settext("<html>line1<br>line2</html>");
but i find it's ugly using html,
is there anyother way to create new line in JButton's Text

As for the above comment....
I thought the question was well purposed. Using HTML was not acceptable in this instance, which was made clear, so why critisize his comments? "Using HTML" is a poor solution, it does NOT work in many instances due to browser, OS variations. Usually the "common answer" is never a COMPLETE answer.
Possible Solution:
Use JLabels to render the text on the button.
import javax.swing.*;
import java.awt.*;
public class ButtonMaker {
public static void makeButton(JButton jb, String[] titleList) {
jb.setLayout(new FlowLayout());
for (int i = 0; i < titleList.length; i++) {
JLabel tmpLabel = new JLabel(titleList);
tmpLabel.setForeground(Color.black);
jb.add(tmpLabel);
public static void clearButton(JButton jb) {
Component[] cList = jb.getComponents();
for (int i = 0; i < cList.length; i++) {
if (cList[i] instanceof JLabel)
jb.remove(cList[i]);
Known Limitations:
1. Flowlayout does not work well with single line text buttons... perhaps another layout manager may work better for various buttonsizes-linenumber combos.
2. Mac OSX : The default UI for Mac OS X (and above it seems), is to have rounded edged buttons. These rounded edges are destoryed when using JLabels, leaving a square, blocky button in its place.
POSSIBLE SOLUTION:
(this is ugly and time consuming)
- create images of the button with text on them.

Is it possible to make Multiple Broadband connecti...

Hi
I have been using BT broadband for some years using a BT Homehub 1.5.
My Freesat box is plugged in to my Homehub, so that I can reliably get BBC iPlayer on the main household TV, so I am unable to move the hub to improve wireless reception elsewhere in the house.
The wireless connection in most of the house is OK, but in one room the reliability is poor and often signal strength shows as low. There is a phone line in this room and I was wondering whether it is possible to make a connection to this line using either a separate modem (Speedtouch 330), or a second hub.
If this is a possible solution then the computer connected to the new modem would affectively be a wired connection, leaving the wireless option still available to the homehub. Both the new modem and the homehub would need to be able to access my BT Broadband account.
If this is technically not possible I seem to have options of using an ethernet connection from the 'poor reception' room to my hub (not really practical as the house has solid floors and routing the cable would be a nightmare), or perhaps upgrading my hub (and wireless dongle) to a later version. Any advice would be very welcome.
thanks

Hi,
this looks good.
Would it be worth upgrading the hub and dongles at the same time or is this overkill
MalcDu
No, I would strongly advise that you keep using the home hub 1.5, as in my opinion, the version 1.0 and 1.5 are the most stable of the home hubs, and do not have some of the problems of the later versions.
If you want to add extra wireless coverage, then an additional wireless access point is the best option, connected to the far end of the powerline adapters.

Is it possible to make a .MOV file "un-downloadable"

Hi there...
I have a weird question - is it possible to make an online video (.MOV file) "un-downloadable"?
I work at a college and a professor wants to post some videos within the school's public site. But, because of his concern with copyright, he wants to make it so the videos are impossible to download to the viewers' local machines.
Is there any type of setting or code that can be put within the .MOV file that would allow this to happen?
Thank you so much for any feedback you have!

Any browser viewed QuickTime file will be "cached" (stored on the viewing computer). This is how browser work (they keep a copy of every page element) to help speed up viewing.
QuickTime 7 (Mac and PC version) even allows the user to set the size of this cache so movies can be viewed while "off line".
True "streaming media" (served with special streaming server software) is not cached on the viewing machine so no local copy is made. Streaming Server (QTSS) is free software available from Apple.
What your school probably really wants is a way to prevent "copies" of your files being used. This is nearly impossible as anyone that views the file could use screen capture software to get a copy. Even the true streaming version.
I use Snapz Pro.
You could use some type of "log on" Web page to help limit the audience.
You could also use "skin track" movies which make screen capture a bit of a chore.
http://homepage.mac.com/kkirkster/MTV/
My example will open in QuickTime Player. Even Pro users are prevented from saving or editing the file because it is protected by an AppleScript droplet "Save As Un-Editable" and modified for Tiger and QT 7.
Hope this helps you decide a plan.

Make graph line transparent programmatically

Hi,
I would like to be able to make graph lines transparent from within LabVIEW. Is this possible? I can find property nodes for every other property, but I can't see the one which turns on the Transparent bit. Any suggestions?
Thanks,
Ian
Solved!
Go to Solution.

Hi Ian,
By "graph lines" I assume you mean the plotted data? If so, then you could use the property node for "plot color", change it to write and then wire a color box constant set to transparent (T) to it.

How to Make a line of text smile?

Is it possible to type on a path in Motion, so I can then animate the path and make a line of text look like it is smiling? Or any advice as how I can go about this?
Thanks

I have not watched the tutorial, but was going to post that I used a 3 point bezier open line shape that I keyframed into a smile, used that as the shape in a "Geometry" layout and it worked fine...
It was a bit slow to render, but not too bad. Sorry I didn't keep it to post online...

Is it possible to have multiple lines on a phone but only have one of the number ring on that phone?

I have a client who has four number on his phone. Extension 4709 is the clients number. He also has 4715,4725 and 4712 on his phone. Is it possible to make it so only 4709 will ring on his phone? The client is running CME 10.0

Hi Joseph,
This would be configured using the "button" (s=silent separator) command;

button
To associate ephone-dns with individual buttons on a Cisco Unified IP phone and to specify line type or ring behavior, use the button command in ephone configuration mode. To remove an ephone-dn association from a button, use the no form of this command.
button button-number {separator} dn-tag [,dn-tag...] [button-number{x}overlay-button-number] [button-number...]
no button button-number {separator} dn-tag [,dn-tag...] [button-number{x}overlay-button-number] [button-number...]
Syntax Description
button-number
Number of a line button on a Cisco Unified IP phone that is to be associated with an extension (ephone-dn). The maximum number of button-ephone-dn pairs is determined by the phone type. Note The Cisco Unified IP Phone 7910G has only one physical line button, but you can assign it two button-ephone-dn pairs.
separator
Single character that denotes the characteristics to be associated with this phone button. Valid entries are as follows: •: (colon)—Normal ring. For incoming calls on this extension, the phone produces audible ringing, a flashing icon in the phone display, and a flashing red light on the handset. On the Cisco IP Phone 7914 Expansion Module, a flashing yellow light also accompanies incoming calls. •b—Beep but no ring. Audible ring is suppressed for incoming calls, but call-waiting beeps are allowed. Visible cues are the same as those described for a normal ring. •c—Call waiting. Provides call waiting for secondary calls to an overlaid ephone-dn. See also the o keyword. •f—Feature ring. Differentiates incoming calls on a special line from incoming calls on other lines on the phone. The feature-ring cadence is a triple pulse, as opposed to a single pulse for normal internal calls and a double pulse for normal external calls.
•m—Monitor mode for a shared line. Visible line status indicates whether the line is in-use or not. Monitored lines cannot be used on this phone for incoming or outgoing calls. •o—Overlay line. Multiple ephone-dns share a single button, up to a maximum of 25 on a button. See also the c keyword. •s—Silent ring. Audible ring and call-waiting beep are suppressed for incoming calls. The only visible cue is a flashing ((< icon in the phone display. Note In Cisco IOS Release 12.4(4)XC and later releases, the silent ringing behavior is overridden during active night-service periods. Silent ringing does not apply during designated night-service periods when the s keyword is used. •w—Watch mode for all lines on the phone for which this directory number is the primary line. Visible line status indicates whether watched phone is idle or not.
dn-tag
Ephone-dn tag that was previously defined using the ephone-dn command. When used with the c and o keywords, the dn-tag argument can contain up to 25 individual dn-tags, separated by commas.
x
Separator that creates an overlay rollover button. When the overlay button specified in this command is occupied by an active call, a second call to one of its ephone-dns will appear on this button. This button is also known as an overlay expansion button.
overlay-button-number
Number of the overlay button that should overflow to this button.

Is it possible to make an alert message.

Hi,
Anyone knows if it Is possible to make an alert-message that pops up ( f.e as a little window) on a specific day to remember me of something I have to do that day?
Would be handy.
Is this possible with Tiger or is there a third party application that does the trick?
Thanks in advance.

Is it possible to make a copy of the Leopard install DVD?

Is it possible to make a copy of the Leopard install DVD? If so, is there a special way this has to be done? I just found out that we needed to use the Leopard install DVD to recover a complete backup from Time Machine after a recent hard drive failure. We have the family pack of Leopard, so I would like to keep the original at home and send a copy when my daughter goes off to college in case she needs to recover again. Her machine was originally a Tiger MacBook, so those install disks will not work. If it is not possible to copy the DVD, is there a way to create a bootable utility to do a time machine recovery?

This half-solved my problem. I have had no problems creating a backup copy for my intel based computers, but non-intel based computers are problematic; a G5 powermac tower and a G4 Powerbook. Both with super drives for single density burning. Both have Leopard running, installed from an install disc purchased from Apple. However, neither will mount the copy, but intel based computers will. have burnt/burned with both toast 9 and Disc Utility. Discs won't mount and are "spit out" by the drive.
