How to disable individual elements in array

How do I disable individual elements in an array at runtime.

I assume you are referring to the control property "disabled".
If so there is no way to disable a single element of an array. By definition an array is a collection of data, it is not a collection of controls. A fine line but an important one. So you can configure the single control that makes up the array and defines its type. For example, if you have an array of Booleans, you can change the color of the Boolean. However this will change the color of all the Booleans in the array. It is 1 control, with a lot of values.
Part of the reason for this is memory. Imagine an array of 1 million elements. If you could set the properties of each element, then to store that array would be incredibly large. It would be 1 million U8s for example, but then all the properties for each 1 million elements would also need to be saved. Therefore your 1 million element array of bytes could easily represent 100 million bytes in memory.
Let me know if this explanation makes no sense, I usually explain it better, but I think I need more coffee.
The way around this is clusters. You can change each element in a cluster, so if your array is of a manageable size, change your array control into a cluster of n elements. You can then use the cluster to array function to convert the data to the array of data you need. Unfortunately this method means that before runtime you must know the maximum number of elements you will need. You can always hide the extras, but you can not create more during execution.

How to disable an element of array?

Hi,
Here i have written VI that will make an array of meaningfull data, for example: data pattern 23 16 16 24
So whenever two consecutive 16 occurs, VI will delete one 16 from data pattern. But in my case wht problem i am facing is:
Whenever it deletes 16 from data pattern, it will show 0 in place of 16 but i need that cell fully disabled unless this 0 will count into mu data pattern.
So i am trying to use disable property node for greying that particular cell or can any tell me why 0 is coming into array when it deletes 16 from it.

Hi Puneet,
from what I see in your screenshot the described behaviour is resulting from an unhealthy combination of using (hell a lot of) locals in combination with "use default if unwired" case structure output tunnels
Remove locals (you already have a shift register, so use a wire instead!), use more descriptive names than "array", wire all output tunnels to avoid unwanted behaviour of your vi...
Why do you compare with an array (in your for loop) when you only need the result for the first element? Compare with scalar instead...
Why is "DLE Check" of type DBL? You only seem to use it as integer...
Why do you write to terminal "Array" and a local "Array" after the FOR loop? (Here is probably the root of the problem!) Only one of the write operations will be effective and you don't know which one...(possible explanation: the local array gets an array formed by autoindexing. So this array contains data for each iteration including an zero [because use of "default if unwired"] when you initially wanted to delete that very element!)
Aditional note:
Next time you attach a screenshot please use a picture format like PNG (as long as you don't use BMP)!

Using Scrollbars and also to disable individual element.

I need to display two dimensional array of checkboxes using Labview 7.1. The two dimensional array should have row headers and column headers.
Also the row headers and column headers are to be scrollable. I was able to make separate scrollable row and column header array.
But this the scrolling cannot be apllied on the two dimensional array of checkboxes. I tried but was able to make it one way only, that is scolling the row header array also scrolls the checkbox array row-wise but not column-wise.
There is another problem with the two D array of checkboxes. My application needs some of the checkboxes to be disabled and others enabled. Since array does not allow individual elements to be disabled , i cannot use array .
So please suggest how to go about this. I have attached a sample VI to explain .

Hi Hema,
Would it be acceptable for your application to use only one table, as shown in the attached idea.vi ?
Instead of booleans, you have can compute 0/1 value, no ?
Otherwise I don't know how to do...

How to disable individual field of a search view

Hi All,
Is there a way to disable individual search field of an advance search view ?
The reason for this is that for a particular search field I am defaulting the value and do not want the user to be able to change this default value, in effect filtering out their search.
I have tried get_i method but the advance search (thtmlb:advancedSearch) does not seem to trigger the get i method, disabled just disable every fields likewise the global edit/viewgroup context.
Thanks in advance for your assistance.

Hi,
I checked it now and found that the GET_I_FIELD is not getting triggered. Sorry for my wrong solution.
You can use the rt_result parameter in GET_POSSIBLE_FIELDS method in IMPL class.
It returns the search fields visible in the view.
Regards,
Arun Kumar

I would like to stress that this NOT the SAP recommended way of controlling the properties on UI elements - the first solution you were give would be the recommended approach. The direct UI coding access should be used as a last resort when working with dynamically generated UI elements. Otherwise you should always try and set the UI element properties via context binding. This makes your application more accessible to customizing/personalization, makes it easier to maintain over time and provides the best performance.

How to disable PS Elements 10 splash screen?

I'm frustrated that I get this Welcome screen everytime I start Photoshop. How do I turn it off?
I just want to start editing, like in the full version.
I FOUND IT. For anyone wanting to do the same thing:
1. Do NOT go to the Edit/Preferences menu in Photoshop. Not there.
2. At the Welcome screen, click on the "settings" in the upper right corner.
3. Choose "Always Launch Photoshop Elements Editor only."
4. You are done.

Welcome to the forums, Tom.
Well, actually, that's one way, but the thing is that the welcome screen still runs background processes when you turn it off that way. Better to go into the program files and make desktop shortcuts to the editor and/or organizer in windows or make dock icons for OS X.

How to disable Photoshop Elements 4.0 from opening up.

Hi all, just wanted to thank all of you for answering my two other questions I had. My question now is when I start up Photoshop Elements 4.0 up it goes through alot of info before it actually opens up to view my pic's. Is there a way to just open my pic's up without it going through Photoshop's window first? Can I disable that start up feature?
One more quick question. When opening up any pic's it automatically open up in Photoshop. I don't want it to do this I want to open pic wherever I want. Thanks again all for you great help.
[email protected]

While in windows, right click on an image file, go to "open with" and choose the program you prefer--it was probably "windows picture and fax viewer"(or something like that) before you installed PSE--and check the box "always use this program".
You need to do this for all of the image types you want to open with the alternate program: jpg, gif, etc.

How to disable individual operations in a service in ALSB 3.0?

Hi all,
We are using ALSB 3.0 for our service developments.
we have WSDL based services. The service accesses different back ends in each of the operations. We would like to disable few operations in production when the back end is not available (because they are behind schedule). Is there any way to achieve this functionality?
Thanks
Manju

OSB doesnot support disabling at operations level in a WSDL out of box though it would be very nice to have feature for your use-case. The use case can be accomplished by creating appropriate logic in the pipeline.
Proxy--(Pipeline )---(If operation is in production=true )---->(Invoke your Actual BS with operation)
Proxy--(Pipeline )---(If operation is in production=false )---->(raise error explaining that this operation is not in production )
http://wiki.oracle.com/page/Usecase%3A+Exposing+a+pratially+implemented+service+via+OSB
Once all the operation are in production, remove this logic from the pipeline. I have made few assumption here regarding you use-case. Let me know if this doesn't solve you issue.
Thanks
Manoj

How to disable one single element in a 2D array?

Hello,
I would like to disable one element in a 2D array. its size is constant at least.
I can change its value by using a 1D array of cluster, but I can't use the property mode easily to disable an element.
If you have any idea, it will be great.
Thank you for your help.
Lolopuf

Right click on the particular control you want to disable and change the properties on that. To do it programmatically, create a reference for that specific control and set the Disabled property for that.

How to declare value binding to array list element in a pojo?

I have a POJO called P, that contains an ArrayList member called w.
class P {
private ArrayList w = new ArrayList(5);
w is initied in the class constructor.
The POJO is in the SessionBean and I would like to reference individual
elements in the ArrayList via a value binding like so;
#{SessionBean1.instanceOfP.w[5]}
I'm not sure how to declare the getter/setter for member W in POJO P
so that setter and getter injection work.

You may not be able to directly set the indexed value.
Try some thing like this.
Add a property that returns the indexed value.
Ex. if you ArrayList objets are of type "String"
int index = 5;
public String getMyValue(){
return w.get[index]
Now your value binding would look something like
#{SessionBean1.myValue}
BTW, if you want to access different index, create another method
public void setIndex(int index){
this.index = index;

How to delete an element in an array...(simple way)

hi,
Newbie here... please help how to delete an element in an array list?
there are alot of codes but they're complicated for a newbie like me..
(simple codes would be better ..:) thank you...

i think u got..what i'm saying.
thnx..Mak,
Say we wish to delete the second element of an array a[1]. Do you really believe that a[1] = a[2] somehow magically deletes a[1]? I really don't think so Tim.
Two eggs, minus 1, equals two eggs? Interesting theory, but I think you're probably wrong.
*@OP:* My advise is just use an ArrayList.

How to Disable/End Date an Element Link/Element in HR 11.5.7(Fam.Pack G)

We want to disable some element links that are no longer valid. These element links are assigned (element entries) to certain employees based on the eligibility criteria set (e.g. Organization/Job/Grade/etc). However we want to disable these elements from a specific date onward as they are no longer valid. I tried to end date either the element entry or the element link but I got the message "Field is protected against update".
From help the only thing I found regarding deleting an element is to delete all element entries linked to that element link and then delete all element links linked to that element to be able to delete or end date the element.
But what we need to do is only to disable the element links and not to delete them all together and lose any historical records related to these element entries.
If anyone has any idea on how to deal with this issue will be highly appreciated.
Thanking you in advance.
Elena

Hi again,
I made a search regarding elements/links and managed to find an old document (2002) regarding links and following the suggestion there I managed to end date the element links in request.
In order to end date the Element Link since it does not allow
you to make any updates you have to try to DELETE it and then select END DATE instead of PURGE.
Thank you!
Best regards,
Elena

Move element in array individually

Hello
I'm trying to make a vi that could move individual element in an array
What I did was, I have a pict ring in an array so that I can have as many picture that I need
But the problem is, if I want to move the picture, I'll end up moving the whole array
Is there any way that I could try, to be able to move only the element?
In the vi that I attached, if I link Node-TCP-FTP, I can then move those 3 at the same time
I'd like to be able to produce several of Node-TCP-FTP so that I can connect the nodes to each other later
I'm trying to make each Node-TCP-FTP pair to be independent so that user can move it wherever they like before connecting node-node
I tried using array, but it gets mix up in the end
It won't be a good thing if I limit the number of Node-TCP-FTP pair that the user can make if I were to use separate ring for each of it
Is there any other way that I could try? or is it possible to move the selected element from the array so that I can make an array of Node, TCP, FTP instead of what I've done?
Thanks

Your description is very confusing to me. You talk about having arrays and multiple inpdependent pairs of these objects, but you only have one set of objects set up and they don't have anything to do with arrays.
I think you should probably be working with picture controls rather than picture rings. Search the forums, I think Ben had a large nugget on working with pictures.
PS. There is no such word as "traffics". It should be "traffic".
