Modify VI during runtime
Dear LabView users,
I have a quite general question about project development what requires continuous control of the hardware. To be more specific, I am developing LabView control and DAQ softwares for large volume calorimeters in the last 2 years. Such a device requires several PID controls, and it has many subsystems. Due to the large heat capacities, it takes about 3-4 days to start up the system. So if I need to modify for example something in a final stage fine control of a specific subsystem, I have to shut down the LabView code, I modify the specific part, I restart the system, I wait 3 days, and then I can see the result of my changes.
My question is kind of general: what is the common, lets say the "best practice" to avoid such a dead time?
Is it possible to change a VI during runtime?
I understand that, if I run independent VIs, what take care of the subsystems, I could avoid this problem. But if I have already a compact "main" VI, including all the subVIs, what can I do?
It would be nice to have a kind of "hot swapping" feature in LabView, so during runtime of my project's main VI, I could edit the subVI what I want, and when it is ready to activate, the runtime engine would swap it with the old version.
Thanks for any advice and opinions!
Best Wishes,
Solved!

Can you modify your algorithims to use parameteric data? If so you can input those control parameters in a variety of ways external to the code itself and change the behavior of the running code. If you need to maodify the code itself you will need to call the code dynamically. If you do so though you will need to make sure you actually load the code right before it executes otherwise you run the risk of using code in memory.

Can I create a dynamic number of inputs during runtime?
Can I create a dynamic number of inputs during runtime?
Oracle 11g
Application Express 4.0.2.00.06
Here is my problem:
We have a table that holds metadata about files (hardcopy or softcopy files).
We expect we may need more columns in the table at some point and don't want to modify the table or the application.
So in order to do this I would like to create:
A table called TBL_FILE with the columns:
TBL_FILE_ID NUMBER (This will be the primary key)
TBL_FILE_NAME VARCHAR2(1000) (This will be the name of the file)
A second table will be called TBL_FILE_META with the columns:
TBL_META_ID NUMBER (This will be the primary key)
TBL_FILE_ID NUMBER (This will be the forign key to the file table)
TBL_META_COLUMN VARCHAR2(30) (This is what the column name would be if it existed in TBL_FILE)
TBL_META_VALUE VARCHAR2(1000) (This is the value that record and the 'would be' column)
So a person can have as much meta data on the file with out having to add columns to the table.
The problem is how can I allow users to add as much data as they like with out having to re develop the page.
Other things to note is that we would like this to be on a single page.
I know how to add we can create multi-row inserts by using a SQL Query (updateable report),
however the TBL_META_VALUE column in the TBL_FILE_META will sometimes be a select list and other times a text box or number field.
So I don't see now a SQL Query (updateable report) would work for this and I can't create an array of page items at run time can I?
Any idea's how I could accomplish this? Is there a better way of doing this?
Also is there a term or a name for what I am doing by creating these 'virtual' columns in another table?
I found this method when looking at Oracles Workflow tables.Welcome to the Oracle Forums !

Creating Page Items dynamically is not available. You will have to create excess items and hide/show , etc. But you cannot change the Item Type. All in all, too many limitations in this approach.
>
Other things to note is that we would like this to be on a single page.
>
The 100 item limit will hit you if you go with extra item on page. With Tabular Form that should not be a limitation, unless you are exceeding the 50 item limit of APEX_APPLICATION.G_Fnn items, and the 60 column limitation of Report region with "Use Generic Column Names (parse query at runtime only)" of Dynamic region.

If the type if item is variable it only means you need a way to store the item type. Meta Data of the Meta Data.

Yes, you can do it. Updatable report/ Tabular Form query can be constructed from the Meta Data using PL/SQL Function Returning SQL Query . It will be a bit of coding in PL/SQL where you use the Meta Data and the Meta Data of the Meta Data to piece together your SELECT with the right APEX_ITEMs. It might have a performance penalty associated with it, but will not be a serious degradation.

Remove pushbutton during runtime
HI experts,
how can I remove a pushbutton during runtime from the screen?
if certain conditions are true than I have to remove the pushbuttons from displaying.Hi,
Take the group1 for the textbox (i/o field) which need to be hidden on a certain condition as ABC using the attributes of the textbox.
Now use the code to hide the button on a cretain condition.
if <condition>. "condition as per your requirement
loop at screen.
if screen-group1 = 'ABC'. "group1 for i/o field defined in its attributes
screen-invisible = 1. "to hide the i/o field
endif.
modify screen.
endloop.
else. "if condition is not true then display i/o field
loop at screen.
if screen-group1 = 'ABC'. "group1 for i/o field defined in its attributes
screen-invisible = 0. "to display the i/o field
endif.
modify screen.
endloop.
endif.
Hope this helps you.

To change view property during runtime
Hi,
I have a scenario where we have 2 views embedded in a window.
First View's property is set to True and second View's property is set to false.
We have a button say "show view" in first view and now we want to change the second view's property to True on click of that button i.e we want to change the view proerties to True during runtime.
We are unabelt o achieve this thruogh plugs are first view is in another DC and second view is in other DC.
Is there any other way to through which we can achieve this?
Any help is this regard is highly appreciated.
Regards,
Richa SinhaHi,
I got your requirement,
Yes if you want navigate back to source view, the problem is you cannot add the the Comp2 again in Comp1 as used comp. This will give cyclic dependancy error.
Try like this.
In Comp2, create an additional view like NavigationView (for example).
In NavigationView create two ViewContainerUIElements (ViewContainerUIElement1 & ViewContainerUIElement2).
Embed this NavigationView into Comp2Window and remove View1's Inteface view & View2 from this window. Change the NavigationView property to true.
And go the Comp2Window Navigation Modeler, embed View1's Inteface view in ViewContainerUIElement1 & View2 in ViewContainerUIElement2.
Now create two context attributes View1Visibility & View2Visibilty in NavigationView and modify the type property to WDVisibility.
Bind these two attributes to corresponding ViewContainerUI elements.
Now in Navigation view, You can create one button and in that button action you can control the visibility of these views.
Hope this info helps. If you need more clarification or info please let me know.

Edit Button text during runtime (Javascript )
I am able to display the contents of a button's text.. using
xfa.host.messageBox("" +EditButton.caption.value.text.value);
however if I try to change that value, it does not change. Is there a different property to modify to change the value of the text on a button during runtime?Hello Andrew,
In JavaScript, try this:
b On Click Event.
> xfa.resolveNode("this.caption.value.#text").value = "New Text";
It should work...

A question about how to change a button in a JPanel during runtime
I am a beginner of GUI. Now I am trying to change a specific component, a button, when the application is running. For example, I have 3 buttons in a JPanel. Each button has its onw icon. If I click one of them, it will change its icon, but the other two don't change. I don't know if there is any method for changing a specific component during runtime. If any one knows please let me know, I will appreciate that very much!!!
What you're going to have to do is loop inside the actionlistener but still have accessability to click while its looping. I don't know much about it, but I think you're going to need a thread. Try something like this... (it doesn't work yet, but I have to take off)
import java.awt.*;
import javax.swing.*;
import java.awt.event.*;
class buttonxdemo extends JFrame implements ActionListener{
Buttonx mybutton;
//set it all up, make it look pretty =]
public buttonxdemo()
mybutton = new Buttonx("default");
getContentPane().add(mybutton.thebutton);
mybutton.thebutton.addActionListener(this);
this.setDefaultCloseOperation(3);
this.setSize(200,200);
public void actionPerformed(ActionEvent ae){
if (ae.getSource() == mybutton.thebutton)
if (mybutton.keepGoing)
mybutton.keepGoing = false;
else if (!mybutton.keepGoing)
mybutton.keepGoing = true;
mybutton = new Buttonx(/*Icon,*/"My Button");
//getContentPane().remove(mybutton);
//getContentPane().add(mybutton.thebutton);
mybutton.startstop();
}//actionperformed
static void main(String args[])
new buttonxdemo().show();
} //movingicondemo
class Buttonx extends Thread{
public boolean keepGoing;
//public Icon ICx; //perhaps an array, so you can loop through?
public String strbuttonx;
public JButton thebutton; //may have to extend JFrame?
public Buttonx(/*Icon IC,*/ String strbutton){
//ICx = IC;
strbuttonx = strbutton;
thebutton = new JButton(strbuttonx);
public void startstop()
int i = 0;
while (keepGoing)
thebutton.setLabel(strbuttonx.substring(0,i));
//if an array of Icons ICx
//thebutton.setIcon(ICx);
i++;
if (i > strbuttonx.length() - 1)
i = 0;

How do I create multiple objects during runtime?
I don't know how to create multiple objects during runtime, here's my problem:
I get a String as input. Then I create an object called newobject. I put the object in a hashtable with the above string as key.
Then comes the problem, in order to create a new object, I have to rerun the same class, which uses the same name (newobject) to create a 2nd object. Now my hashtable doesn't reference to my 1st object anymore...
Is there anyway I can fill up the hashtable with different objects, and make each key point to each object it was supposed to?
For those who want to see a bit of the program:
public class PlayBalloon{
public Hashtable ht = new Hashtable();
for(){
Balloon pB = newBalloon;
newBalloon=new Balloon(pB);
ht.put("Some input from user", newBalloon);
for(){
ht.get(s).draw;<= s=string, draw=own meth. in Balloon
}I think i can see the problem that you are having. You have, in effect, duplicate keys in your hashtable - ie, two strings used as keys with the same name.
The way that a hashtable works is as follows...
When you ask for a value that is mapped to a key it will go through the table and return the first occurence it finds of the key you asked for. It does this by using the equals() method of whatever object the key is (in your case it is a String).
If you cant use different Strings for your keys in your hashtable then i would consider writing an ObjectNameKey class which contains the String value that you are trying to put in the hashtable and an occurrence number/index or something to make it unique. Remember to override the equals method in your ObjectNameKey object or else the hash lookup will not work. For example
class ObjectNameKey {
private String name;
private int occurence;
public ObjectNameKey(String name, int occ) {
this.name = name;
this.occurence = occ;
public String getName() {
return name;
public String getOccur() {
return occurence;
public boolean equals(Object o) {
if (!(o instanceof ObjectNameKey)) {
return false;
ObjectNameKey onk = (ObjectNameKey)o;
if (onk.getName().equals(name) && onk.getOccur() == occurence) return true;
return false; -
How to determine the target system during runtime of a Generic DS?
Hi Experts, good afternoon.
I am coding a Generic Extractor using Function Module. I have to select the field TIMESTAMP on table ROOSPRMSC. To do so, I need the value of RLOGSYS that is the BW system that is calling the Extractor.
Do anybody knows how to determine via ABAP the RLOGSYS (Remote Logical System) during the runtime of the Generic DataSource Function Module?
The table ROOSPRMSC keep the TIMESTAMPs values of the last delta upload for each DataSource and for each BW target system. As I have 2 BW's loading data from the same SAP ECC system, I need to know, during runtime of my Generic DataSource, the actual system that is requesting the delta. That's the reason why I need to know the BW's logical system name that is "runnig" the delta InfoPackage.
Plese, help!!!
Thanks in advance!
Leandro VaniLeandro,
The calling program of your FM should have a local variable I_RLOGSYS which is populated with the BW server ID.
If you don't know how to access a variable in a program that is in call stack using field symbols, search SDN.
I haven't tested this, so you may have to explore a little.
Good luck. -

Please anyone help me on this?
Thanks -
I'm very new to LabVIEW and every day I learn such a lot about LabVIEW. I did not find any example according to my problem, but I don't know how to do the following :
In the MainVI I read different strings from file in an array (In the example below I defined them as constants. The example only shows how the frontpanels should look like).
During a loop I calculate different values, which will be written in an array, too, and in every loop the array of values will be overwritten with the new calculated values. (string[i] belongs to value[i])
Now, by pushing the button 'sub' during runtime, I want to op
en the Frontpanel of a SubVI, on which you see a Ring and a numeric Indicator. Now, I want to show the strings I read in the MainVI as items in the Ring-menu. If I choose one of the items (strings) in the Ring-menu during runtime, I want to show the accordant value, which was calculated in the MainVI, in the numeric Indicator, and in every loop the new calculated value should be shown in this Indicator automatically.
So I have two questions:
1. How do I put the strings into the Ring-menu during runtime?
2. How to open a SubVI-Frontpanel during runtime, and how to pass the calculated values to it?
Every answer I accept with thanks!

sub.vi 9 KBSee the atttached vis :
1/ Pass the string array to the sub-vi, then use a property node to replace the ring node strings
2a/ From the subvi front panel window, rightclick on the icon, and select "Show connector". Define the connections
2b/Set the sub vi properties (right click on the vi icon, select "VI properties... >> Window appearance..." go to "customize...", and checkmark the "Show front panel when called" item).
3/ your main vi should run 2 separate loops in order to avoid that reading the data stops the aquisition process (if any !..), or the reverse situation.
You should read the LV manual to find out how to create a sub-vi : there are a number a basic things to learn and to memorize...

No mapping during runtime!!
Hi all,
I got stucked with one problem in file-xi-idoc scenario using sap xi 2.0.
I am using sender file adapter which is picking up the file from ftp server. The file contains three fields and I am placing them in a text file as
Sriram,mumbai,in.
The file adapter is picking the file successfully and converting them into xml sending to integration engine. But during runtime these fields are not mapped to target idoc structure (DEBMAS 03) and there are no errors showing in SXMB_MONI. The idoc is going to receiving sap system with error status 51. This is the payload of xml messages observed in SXMB_MONI.
<?xml version="1.0" standalone="yes" ?>
- <resultset>
- <row>
<field0>sriram</field0>
<field1>mumbai</field1>
<field2>in</field2>
</row>
</resultset>
Here is the file adapter configuration :
file adapter java class
classname=com.sap.aii.messaging.adapter.ModuleFile2XMB
mode=FILE2XMB
mode = file2xmbwithrowconversion
Integration Engine address and document settings (example, see docu)
XMB.TargetURL=http://ht56f4:8000/sap/xi/engine/?type=entry

ftp.port = 21
ftp.user = sapftp
ftp.password = ftp***sap123
ftp.connection = permanently
ftp.mode=Text
#file.sourceFilename = bank.txt
##File Adapter specific parameters (example, see docu)
file.sourceDir= \/pssap\/
file.sourceFilename = testing.txt
#file.processingMode=setAttribute
#file.processingMode=archive
#file.archiveDir=c:/temp_archive
file.pollInterval= 60
file.pollIntervalMsecs= 10
#file.retryInterval = 30
file.logPollInterval=YES
file.processingMode=delete
##xml conversion properties if mode FILE2XMBWITHROWCONVERSION specified (example, see docu)
#xml.fieldFixedLengths=8,9,2
xml.processFieldNames=notAvailable
xml.fieldSeparator=,
xml.enclosureConversione = YES
I am not able to test mapping in sap xi 2.0.
Any suggestions greatly helpful.Thanks,
found it.
