Make string indicator scroll automatically to last entry

Is it possible to have a small string indicator on the front panel automatically show the last part of a string rather than the first? We have a situation where we are updating a long string (adding to it) and prefer to see the latest additions without using a scroll bar but still (rarely) be able to scroll to the top.
Thanks, Peg

Make a property node for the string indicator, set to write, and set the property to "Scroll Position". Then just wire a very large number to it or get the length of your string (string length under string pallete), and wire that in.

How to remove the last line input into a string indicator??

I am currently working on a program where the user has the ability to create a profile for one of our lab machines to run. When the user selects what parameters they would like, a string indicator shows the user the last input they set followed by a comma. For example, if the user selects which profile they want, and the times they would like to set, the following string would be displayed:
As you can see in the picture above, the profile is updated in the string indicator after every set button is hit. In the event the user makes a mistake, I want them to have the ability to delete the last line that was added.
This is the code I developed so far. The string coming in and leaving is attached to a shift register so it continues to append to the indicator. I tried in this case to count how many lines have been written in the string so far, and I built an array with the current string. Using the delete from array.VI I indexed it to the number of lines that was created so that the last line is deleted. I unfortunately had no luck. Any suggestions?

Hey Tbob,
That almost worked. The only issue though is it leaves a null string in its place without moving everything after up one line. Also, if i have a parameter repeating multiple times, it doenst seem to work.
I'm confused. If you are deleting the last line, how can there be anything after? What do you mean by a parameter repeating multiple times?
If you look at my example front panel, you will see that the last line is deleted. Isn't this what you asked for?
It's due to the fact that your constant doesn't have a comma in the last line. If you add that in, you should be able to reproduce his problem. This is just a guess though, I didn't actually test it to see.

Force a string indicator to scroll to the bottom

In LV Web UI Builder is there a way to force or programmatically scroll a string indicator to the bottom?
I am building a virtual hyperterminal and I am writting a very large amount of data into a string control. I have the vertical scroll bars turned on, but by default it just shows the information at the top. I want to include all of the data so that the user can scroll back to see the history, but it would be nice if by default the scroll bar would stay at the bottom.

I just wanted to confirm there is no way currently to force a string indicator to scroll to the bottom. I will note this down as a product suggestion for the Web UI Builder team.

Change the colour of lines in the same string indicator.

Hi everybody,
I'm getting crazy, because I'm looking for the way to change the colour of
the lines I want in the same string indicator.
I'm doing an application to control an instrument by serial port, and I'm
concatenating the lines that this instrument gives me, but there is some
line that I would want to change its colour, because there has been an alarm,
for instance. And I only can change all the string.
Is there any way to do this? I don't know.
Could you please help me?

Thank You Very Much.
The fourth step is a little bit difficult to understand, but what I've done
is all the three first steps, and in the fourth one I've made an array (I32)
of the lines that I don't want to highlight and connect it to Disabled �tems.
Do you think this is a good solution?
Thank you again for your help. I really needed someone to help me, because
if not I would still be with the STRING INDICATOR.

Saving text written in a string indicator on the front panel

Hi,
As a new LabVIEW user I'm trying to type a manual to explain how to use the software program I'm writing. I would like to display it on the front panel in one of the tab windows. There is quite a lot of writing and I would like the user to be able to scroll through the text. I tried inserting a string indicator, right clicking on it and selecting 'visible items'>>'scrollbar'. However, when I saved my changes the writing in the indicator was not saved with the rest of the changes. I'd be grateful for any advice.
Thanks,
Adrian

Adrian,
The 'data' in your string indicator was probably not saved as 'default', so that when you closed the VI and re-ran it, it was lost.
For any data (strings, numbers, etc.) that you want to have as default, you will need to rt-click the indicator/control and under data operations, select 'make current value default' (when you have the data entered).
Also - add an Invoke node function to force this indicator to display the default data upon initial running of the VI.
Another way, though, when you have a 'lot' of text, is simply save your info in a text file, and have a VI open the file and display it either as the text file itself, or as input into a string indicator.
Good Luck, Doug

How can I make a indicator transparent grey?

Hi,
I would like to make the background of a string indicator transparent grey on the FP. No Problem making it either transparent or grey, but I don't know how to make it transparent and grey at the same time.
Would anyone know?
Labview 8.5. & XP
Thanks a lot,
Marc

I'm not sure I follow you.
If you make a control or indicator transparent, that means there is no color. Whatever is behind goes through.
If you make it grey, then it is grey. It is not transparent. You can't have both at once..
Now, do you want to see something underneath the control or indicator and see it as grey?
If so, then make the control / indicator transparent and color whatever is in the background grey..
Or maybe I totally didn't understand what you want to do..
Can you post an example code of what you want to do?

I need to rotate a string indicator 90 degrees. Is this possible

To make my front panel less cluttered, I would like to have my string indicator rotated 90 degrees counter clockwise. Is this possible and if so will I be able to place it in an array of strings? Any and all help is greatly appreciated.

How to create a string indicator with a history?

I'm interested in creating a string indicator that has a history to it, possibly with time stamps attached to it.
For those who have used AutoCAD it would be exactly like the command bar. A plus would be if I could only
save the last 100 entries to keep the size memory usage down.
Any thoughts? Does anyone have a code segment of this?

Keep a line count and once you go over your limit search the string for the first new line and split it at that point.

Tab characters in a string indicator box

I have a string indicator box and would like to make text on different lines match up. When I try using the tab character or a \t I only get a single space. Is there a trick to making the text line up?

Whenever the string indicator is too lame for my purposes I usually go with the ActiveX text box.

How can I modify the Stile of a String-Indicator (without the Frame)?

I only want to see the Text-String on the Frontpanel,
without the Indicator-Frame.

Go to the Classic Controls palette, select a Simple String indicator. Then use the paintbrush tool with transparent selected (The T in the upper right hand corner of the color palette) to make the indicator transparent. The text in the indicator will still be visible, but not the indicator frame or background.

*Kudos always welcome
Solved!
Go to Solution.

You can change the colour of a string control background using the paint tool. Choose View > Tools Palette.
Select the lower-most icon of a paint brush.
Right click on the background area of your string control.
A colour mixer will appear - select either a block colour or the T in the upper right corner for transparent.

Why not use an event
Add a While Loop, inside the loop add the Event Sructure.
Now in the event structure selecd the String Controls.value change event to
react
and the new value inside the event that you get,( connect to the String
indicator box.

How to make an indicator takes more than one input

Hello,
I want to know how to make an indicator ( like gauge for example) response to more than one case strrcuture result. In other words, how the indicator can take more than one input and move based on different input values ( the arrow of the gauge moves to different angles basesed on the logic structure and not only to one degree).
Thanks in advance,

YES, you got it right Coastal !
This is what i want to do,
I dont know how to establish this output in the software, i am still learning LabVIEW.
I put a merge block to join the outputs but it didnt work.
check it in the attached VI file.
I am sure it is an easy thing but I dont know how to implement it.
Any help you provide is appreciated,
Best wishes

How can I export formatted text from a string indicator?

Does someone know how I can export formatted text (i.e., parts of the text have different formatting, such as color, fontsize, etc.) from a string indicator? Using copy/paste does not work, as it only exports unformatted plain text.

Hello Sparti,
Thank you for your suggestions, they are all very useful, and I plan to use the HTML feature under Report Generation to export the formatted text from Labview. However, I am still not sure how I can extract the formatted text from a *string indicator* and transfer it to one of those VIs, so that it can be exported to other applications. Let me give some more specific info on what I am trying to achieve: I am monitoring the communication between two pieces of equipment. A string indicator shows all the data flow, with different colors for data coming from different instruments. I managed to do that by using a property node and playing with the selection and font color properties. Now, if you just wire the output of the string indicator, the formatting is gone and all you get is just plain black text (for instance, try to programmatically transfer the formatted text from one string indicator to a different string indicator and you will see that the formatting is not preserved). Even if you try the "brute force" method of manually selecting and copying the text in the indicator and pasting it to Word, LV does not export the formatting. But, if you paste *within* LV (for example, paste it to a string constant in your diagram), then it works. To extract the formatted string from the indicator, I also tried to use a property node, but without success. I am trying to avoid duplicating part of my code to generate the same color-coding scheme on a report. It would be way easier to be able to transfer the formatted text from the string indicator. This is particularly annoying, because the information is there, stored in the data structure associated with the string indicator. But how can I put my hands on it? Any ideas?
