Display string to LCD TV

Hello.
I need help again. This time about : How to display string from LabVIEW to LCD TV? I have two LCD TV, and want to show some "string1" cycle from LabVIEW to first LCD TV1 and "string2" cycle display to LCD TV2.
Any idea?

use a graphics cards, that supports 3 outputs simultanuously, and connect all three displays to your computer.
Simple, eh?
Yup and if you have a laptop you want to use which doesn't have 3 outputs, look into a low cost USB graphics card. The cheap ones aren't good for streaming HD video but work well for normal PC use.

Using Cinema Display and Samsung LCD with One Mini

I have been trying unsuccessful to output the DVI of my mini to my 23" Apple Cinema and my Samsung 4669F (native resolution of 1920x 1080p). I have tried various methods including using the Gefen 1:2 DVI Splitter (Ext-DVI-144) and a DVI-HDMI cable to the samsung in conjunction with SwitchResX, all to no avail.
Any help?- I wish to mirror the same display on both LCD screen simultaneously?- However, I would settle for a solution of a convenient A/B switch? ANy tips?
What about an external USB video card for the Mini- that should work too?- any tips?
I used SwitchResX because I determine that because the 23" ACD was 1920 x1200, the Samsung was not displaying because the Gefen splitter box was sending the same signal in 1920 x1200 to the Samsung, which was not accepted by the Samsung whose native resolution is 1920 x 1080p. However, once I switched the resolution to 1920 x 1080 to force an out of the mini to that resolution, there was no display at all on the 23" ACD and I had to do a safe mode reboot to recover the display on the 23" ACD?-
One would think that it would be relatively easier for Apple to create a script that would allow a person to display 1920 x 1080p on the Cinema Display, a script that overrided the message from the ACD that tells the mac mini to stretch any resolution to 1920x1200 before it gets to the 23" - This way I could use SwitchResX and the Gefen splitter to output 1920x1080p to both displays at once (of course the 23" ACD would have to have some black borders on the top and bottom. Why doesn't apple make this available? - Spent $900 on this monitor and the Mini has a DVI output- why should the Gefen splitter be rendered useless simply because my other display is a different native resolution.

How can I preserve display string (convert DOB to Age) upon excel export?

I am using the following code to convert DOB to age within Display String (Format Field/Common tab):
if
//months
(datediff('yyyy',{CDCLIENT.DOB},currentdate)-(if datepart('y',currentdate)>datepart('y',{CDCLIENT.DOB}) then 0 else 1))<2 then
totext(datediff('mm',{CDCLIENT.DOB},currentdate),0,'') & ' months'
else
//years
totext((datediff('yyyy',{CDCLIENT.DOB},currentdate)-(if datepart('y',currentdate)>datepart('y',{CDCLIENT.DOB}) then 0 else 1)),0,'') //& ' years'
When I export to excel/csv/ttx.. it doesn't export the display string (Age), but reverts back to the DOB. How do I preserve this upon export?

Hi Dominic,
The 'display string' formatted values are not exported to Excel Data Only.
Create a 'formula field' as a workaround.

How to display string with XML content in 4.6?

Hi,
I`d like to know how to display string with XML content in it for 4.6.
4.6 has not method parse_string.
And example like this is not helpful:
DATA: lo_mxml    TYPE REF TO cl_xml_document.
CREATE OBJECT lo_mxml.
CALL METHOD lo_mxml->parse_string
    EXPORTING
      stream = gv_xml_string.
CALL METHOD lo_mxml->display.
Thank you.

Hi,
May be you can use fm SAP_CONVERT_TO_XML_FORMAT. But it have some issues with memory usage, the program consumed tons of memory during convert.

Display String in cross tab in place of blank cell

Hi,
I am using CR 2008 and my issue is when i run crosstab i am getting a blank values fro some data becuase which that criteria there is no data in Database . I need to display a string in that area. How can I achieve this?

Hi Venkat,
There is a Display String formula for fields, accessed by right-clicking the field and selecting Format Field. This is used to tell Crystal exactly what should be displayed for the field. Add the following logic (basic syntax):
if CurrentFieldValue = 0 then
formula = "your display srting"
else
formula = cstr(CurrentFieldValue, "0.00")
end if
This will cause all zero values to display as blank. I added the "0.00" parameter to the cstr() function to show that's how you tell cstr() how you want the number formatted. See the online help for cstr() for details.

Is there something between my display glass and LCD?

I can't tell if this is a dead pixel, stuck pixel, or there is something in between my display glass. I think it is something between my display glass and LCD because when i turn my computer screen off, it appears like a little white speck and when I look at a black screen it appears as a little white speck, as you can see attatched. What can I do about it? This is a mid 2012 MacBook Pro.

A new Mac is in warranty for 1 year from the date of purchase.
You may have to take the computer to the Apple store to have it checked out.

Getting rid of leading zero using display string.

I have a formula:
If {BillHeader.SalesTax} < 0 then
formula = Replace(CStr (-1 * {BillHeader.SalesTax}), "$", "") + "CR"
else
formula = Replace(CStr ({BillHeader.SalesTax}), "$", "")
end if
I need to change this formula so it won't show a leading zero.
ex:
0.00 to .00
0.47CR to .47CR
etc..
I don't have much experience with VB or crystal code. Since this is in the display string I can't use the number formatting. Any ideas? Thanks for the help!

Here is one solution:
1. Comment out the display string code.
2. From the menu, choose "Crystal Syntax".
3. Copy and paste this formula.
If currentfieldvalue < 0 then
 if split(Replace(CStr (-1 * currentfieldvalue), "$", "") + "CR",'.')[1] = '0' then
 '.' & split(Replace(CStr (-1 * currentfieldvalue), "$", "") + "CR",'.')[2]
 else
 Replace(CStr (-1 * currentfieldvalue), "$", "") + "CR"
else
if split(Replace(CStr (currentfieldvalue), "$", ""),'.')[1] = '0' then
 '.' & split(Replace(CStr (currentfieldvalue), "$", ""),'.')[2]
else
 Replace(CStr (currentfieldvalue), "$", "")
PS: In your first formula, you are using sales tax but in the second post, you are using amount due, not sure which one it is, but if the formula is on a display string the above should work.

Can you really use Display String formula to test for NULL

I am trying to manipulate the Display String of a field throught the Format Editor. If a field is null, it should display "N/A", or "No data given", or anything else appropriate I might choose.
I can't get this feature to work and I'm wondering if there's a bug here. I'm using the following formula:
if (isnull() or trim() = "")
then "N/A"
else
Am I doing something wrong or is there a better way to do this?

Hi Adriane
The other way to display "N/A", or "No data given" if a field is null is using a formula with if -else statement as follows:
whileprinting records;
if (isnull() or trim () =" ")
then "N/A"
else
Please let me know if this helps.
Thanks

Help! my System Preference Display shows Color LCD instead of MacBook Pro! Y is is saying this?

Hello people, my MBP's systempref>Display shows "Color LCD" when ity should have been MacBook Pro! YTF is it like that?

It's supposed to read "Color LCD" - there's no "MacBook Pro" color profile (unless you've created one and saved it with that name).

JTable displays string in wrong order : my code problem or Java problem ?

I have the following code that displays data in a JTable, most of the time it works fine, but I've realized when I have a cell with values like : "Snowboarding"+"[123456789]"
It would display it as : [Snowboarding[123456789
For a string like : "Chasing toddlers"+"<123456789>"
It would display it as : <Chasing toddlers<123456789
It not only moved the last bracket to the front, but also changed its direction from "]" to "[" and from ">" to "<"
Is there anything wrong with my code ? Or is this a Java problem ?

* TableSorter is a decorator for TableModels; adding sorting functionality to a supplied TableModel. TableSorter does not store
* or copy the data in its TableModel; instead it maintains a map from the row indexes of the view to the row indexes of the
* model. As requests are made of the sorter (like getValueAt(row, col)) they are passed to the underlying model after the row numbers
* have been translated via the internal mapping array. This way, the TableSorter appears to hold another copy of the table
* with the rows in a different order.
* 
* TableSorter registers itself as a listener to the underlying model, just as the JTable itself would. Events recieved from the model
* are examined, sometimes manipulated (typically widened), and then passed on to the TableSorter's listeners (typically the JTable).
* If a change to the model has invalidated the order of TableSorter's rows, a note of this is made and the sorter will resort the
* rows the next time a value is requested.
* 
* When the tableHeader property is set, either by using the setTableHeader() method or the two argument constructor, the table
* header may be used as a complete UI for TableSorter. The default renderer of the tableHeader is decorated with a renderer
* that indicates the sorting status of each column. In addition, a mouse listener is installed with the following behavior:
* <ul>
* <li>
* Mouse-click: Clears the sorting status of all other columns and advances the sorting status of that column through three
* values: {NOT_SORTED, ASCENDING, DESCENDING} (then back to NOT_SORTED again).
* <li>
* SHIFT-mouse-click: Clears the sorting status of all other columns and cycles the sorting status of the column through the same
* three values, in the opposite order: {NOT_SORTED, DESCENDING, ASCENDING}.
* <li>
* CONTROL-mouse-click and CONTROL-SHIFT-mouse-click: as above except that the changes to the column do not cancel the statuses of columns
* that are already sorting - giving a way to initiate a compound sort.
* </ul>
* 
* This is a long overdue rewrite of a class of the same name that first appeared in the swing table demos in 1997.

* <ul>
* <li>
* Mouse-click: Clears the sorting status of all other columns and advances the sorting status of that column through three
* values: {NOT_SORTED, ASCENDING, DESCENDING} (then back to NOT_SORTED again).
* <li>
* SHIFT-mouse-click: Clears the sorting status of all other columns and cycles the sorting status of the column through the same
* three values, in the opposite order: {NOT_SORTED, DESCENDING, ASCENDING}.
* <li>
* CONTROL-mouse-click and CONTROL-SHIFT-mouse-click: as above except that the changes to the column do not cancel the statuses of columns
* that are already sorting - giving a way to initiate a compound sort.
* </ul>
* 
* This is a long overdue rewrite of a class of the same name that first appeared in the swing table demos in 1997.

Slow Display due to LCD?

Hi fellow Developers out there...
I have just written a VERY simple game, that displays a ball running over a background. The code was inspired by several other postings that I read. It all works fine (so it is displayed and the ball is moving) but if the ball moves more than 10 pixel per frame, then it gets really ugly: You can then see both sides of the ball flickering quite strongly and its not really a smooth animation.
Now my first guess was that my display was causing these smudges, because I have a Laptop and the reaction time probably isn't so great, but then the effect would look different... However I wanted to get the refresh rate of my monitor in order to sync my framerate with it, but it was zero and my system also has no information about my refresh rate (I have a mac).
The next thing I looked at was the sleep for the remaining time of the frame. I monitored the remaining time and it was nearly allways below zero. Now what am I doing wrong? It can't be so resource consuming to display two cached images...
Here is my code:
import java.awt.Frame;
import java.awt.Graphics2D;
import java.awt.GraphicsDevice;
import java.awt.GraphicsEnvironment;
import java.awt.Rectangle;
import java.awt.event.KeyEvent;
import java.awt.event.KeyListener;
import java.awt.image.BufferStrategy;
public class Main implements KeyListener {
    private Frame frame;
    private BufferStrategy strategy;
    private Rectangle screenSize;
    private final static int FPS = 50;
    public Main() {
        GraphicsDevice device = GraphicsEnvironment.getLocalGraphicsEnvironment().getDefaultScreenDevice();
        frame = new Frame(device.getDefaultConfiguration());
        frame.setUndecorated(true);
        frame.setIgnoreRepaint(true);
        frame.addKeyListener(this);
        device.setFullScreenWindow(frame);
        screenSize = frame.getBounds();
        frame.createBufferStrategy(2);
        strategy = frame.getBufferStrategy();
        //Objekte
        Sprite background = new Sprite("background");
        Sprite ball = new Sprite("ball");
        int counter = 0;
        while (true) {
            long startTime = System.currentTimeMillis();
            counter = counter + 8;
            if (counter > screenSize.width)
                counter = 0;
            Graphics2D graphics = (Graphics2D) strategy.getDrawGraphics();
            graphics.drawImage(background.render(), null, null);
            graphics.drawImage(ball.render(), counter, screenSize.height - 220, null);
            graphics.dispose();
            strategy.show();
            try {
                long remainingTime = (1000 / FPS) - (System.currentTimeMillis() - startTime);
                if (remainingTime > 0)
                    Thread.sleep(remainingTime);
            } catch (InterruptedException e) {
    public void keyTyped(KeyEvent e) {
        //nichts tun...
    public void keyPressed(KeyEvent e) {
        if (e.getKeyCode() == KeyEvent.VK_ESCAPE)
            System.exit(0);
    public void keyReleased(KeyEvent e) {
        // nichts tun...
    public static void main(String[] args) {
        Main m = new Main();
public class Sprite {
    private Image frame;
    public Sprite(String name) {
        if (frame == null)
            load(name);
    private void load(String name) {
        Toolkit toolkit = Toolkit.getDefaultToolkit();
        frame = toolkit.getImage(getClass().getResource("/images/" + name + ".gif"));
    public Image render() {
        return frame;
}Thanx for your advice...

System.currentTimeMillis() is a horrible timer, which you can't even use for measuring network latency. It's resolution equals the operating system's tick time (win9x 50-55msec, macos/win2k/winxp 10msec, linux 1msec... iirc). So yea with a basically empty loop you'll usually get 0 msec as difference here (the next bigger step is the tick interval).
There are native timer libs and well with 1.5 you have finally a usable hi res timer (System.nanoTime)... unfortunately mac's 1.5 isn't out yet.
Btw Thread.sleep isn't really accurate, too. You can get it down to about 5msec on all operating systems, but it can always take longer than that (you just tell the OS that you would like to continue your stuff in 5msecs and there is no guarantee that it will be in time).

FCP 6 playback problems in Digital Cinema Display on an LCD External Monito

Hi
Looking for advice.
I am running FCP 6 and have hooked up my Macbook Pro to an external LCD SAMSUNG Flatscreen TV. I want to preview my edit as I cut but Im having problems with playback.
When I hit play the video freezes on the one still image on the LCD, The canvas windows is playing fine but the LCD playback doesnt move... is this a setting/resolution problem?
Im editing in DVCOPRO HD which i thought may be the issue but even when I switched to editing Jpgs or even DV PAL sequences it still does the same thing!
On some occasions BOTH the canvas window and the LCD dont move at all, only when I turn off the External LCD Cinama Desktop Display monitoring does the canvas window play normally.
Can anyone help with my problem?
Im editing on a Macbook pro 17" 2.4 ghz 160GB with a NIVIDIA 8600 Geforce graphics card 256MB 2.0GB RAM running Final Cut Pro v.6
cheers

I was having a similar problem trying but was set up with a 17" viewsonic as my primary monitor (menubar location) and my MacBook Pro as the secondary. I wanted to play back Hi-Def full screen on the MacBook Pro and all I got was still frames (though I could advance a single frame at a time and see motion).
I didn't find an answer here but went exploring in prefs and found a solution that worked for me.
In System Settings > Playback Control I changed "RT:" from "Safe" to "Unlimited"
Now I'm happily watching the full resolution HD video on my laptop screen.
I'd be curious to know if that works with the Flatscreen TV.
All the best,
Kevin

Single Display output (HD LCD TV only)

Hi.
I've connected my iMac to my HD LCD-tv (Mini-dvi -> dvi -> hdmi -> Sourround Receiver -> TV), and the picture & sound quality is excellent. Although the display options only show 1080i on the iMac, both the receiver and the TV confirm the signal as 1080p (the display options allows me two different 1080 settings - and one of them is confirmed by the other HW as a 1080p signal). So no problems there.
The thing is only want output on the TV - not both screens (TV + iMac). Just like my old PC - switching back and forth as desired.. I've exhausted all display settings on the iMac - but no success yet.. Please help..

Never mind - posted this in the correct forum now.

How to display String/text in a JFrame ?

Hi,
I set up a simple browser and pinging a server (say localhost). Then under that server directory, I am looking for a file. Then, I use input or output stream to bounce the text back to browser to display out on the screen. It was successful.
But, just can't display out in a text area (say a frame or something).
The string coming back from server say called s (one line at a time using buffer).
public class VerySimpleBrowser extends JFrame {
public JTextArea t;
public VerySimpleBrowser() {
super ("VerySimpleBrowser");
Box b = Box.createHorizontalBox();
b.add(new JScrollPane(t));
Container c = getContentPane();
c.add(b);
setSize(850,600);
show();
void static main ...
while ((s=fromServer.readLine()) != null)
//System.out.println(s);
t.setText(s);
Then, I got NullpointException error ?! The frame poped out ok, but nothing was written to it.
Thanks for help.
Philip

To save you from pulling all your hair out, here is what you've to do:
String out=""
while ((s=fromServer.readLine()) != null) {
out+=s;
t.setText(out);
.....V.V.
