How to avoid Build Array function inside a For (while) Loop?

Hi there,
I have a simple question about how to avoid using Build Array function inside the loop. Now I want to remove the Build Array funtion inside the loop to improve the performance (To get better memory management). Any idea how to do that?
Thanks a lot!
Warmest regards,
Chong

It's been my experience that using the auto-indexing to build an array
on a For loop is just as good as initializing and replacing elements.
The For loop knows before it runs how many iterations it has to run and
can allocate the array ahead of time.
You're better off initializing and replacing when using a While loop
because it does not know how many iterations it will run and can't
pre-allocate the array ahead of time.

Cascade two Build Array functions - what happens?

I found the the code shown in the attachment in a very complex VI that I am overhauling. Would someone explain to me what is happening with the "cascaded" Build Array functions.
I can see that the first Build Array function builds a 1D array of integers which passes to the second Build Array function which outputs a 2D array of integers but, since there is no Element or second Array input, I don't see how this works.
This is part of a subVI that is not embedded in a loop.
All the examples have at least two inputs. With one input there is no Concatenate Inputs option. There is some implicit operation here that I do not understand.
Would someone explain how this works?

You are taking a scalar value and creating a 1-D array with exactly 1 element.
Then you are taking the 1-D array and building it into a 2-D array, with exactly 1 element.
Since you can't concatenate something with nothing, the only logical mode for the Build Array would be to build it into an array of the next larger dimension.
You could add a third one, then you'd have a 3-D array with exactly 1 element. And so on.

Hi,
Based on the description, I understand that you want to add subreport in the main report. When previewing the main report, the subreport can be shown in detail. Please see the screenshots on my test:
In Reporting Services, we can create parameters and pass them from main report to subreport in order to control the data dynamically.

Hi fais,
Following through with what JB suggested. The steps involved in replacing the inner for loop with a while loop are outlined below.
You can replace the inner for loop with a while by doing the following.
1) Right-click of the for loop and select "Repalce" then navigate to the "while loop".
2) Make sure the tunnels you where indexing on with the for loop are still indexing.
3) Drop an "array size" node on your diagram. Wire the array that determines the number of iterations your for loop executes into this "array size".
4) Wire the output of the array size into the new while loop.
5) Set the condition terminal to "stop if true".
6)Drop an "OR" gate inside the while loop and wire its output to the while loops condition terminal.
7) C
reate a local of the boolean "stop" button, and wire it into one of the inputs of your OR gate. This will allow you to stop the inner loop.
8) Drop a "less than" node inside the inner while loop.
9) Wire your iteration count into the bottom input of the "less than".
10) Wire the count (see step 4 above) into the top input of the less than. This will stop the inner loop when ever the inner loop has processed the last element of your array.
Provided I have not mixed up my tops and bottoms this should accomplish the replacement.
I will let others explain how to takle this task using the "case solution".

How to avoid duplicate posting of noted items for advance payment requests?

How to avoid duplicate posting of noted items for advace payments request?

Puttasiddappa,
In the PS module, we allow the deletion of a component pruchase requisition allthough a purchase order exists. The system will send message CN707 "<i>A purchase order already exists for purchase requisition &</i>" as an Iinformation message by design to allow flexible project management.
If you, however, desire the message CN707 to be of type E you have to
modify the standard coding. Doing so, using SE91, you can invoke the
where-used-list of message 707 in message class CN, and to change the
i707(cn)
to
e707(cn)
where desired.
Also, user exit CNEX0039 provides the possibility to reject the
deletion of a component according to customers needs e. g. you may
check here whether a purchase order exists and reject the deletion.
Hope this helps!
Best regards

How to avoid the Amount and Date values for VOID Cheques

Hi All,
I had created a two window i.e For Amount and Date. If I process the cheque the Amount value and Date should not trigger for VOID CHEQUES.
Can any one tel me how to avoid the Amount and Date values for VOID Cheques
Your help will be greatly appreciated.
Regards
Yathish

Hi,
I dont know which tablel you are referring to, is it PAYR table and the field VOIDR?
If a cheque is voided, it would have a reason and it is stored in VOIDR field of this PAYR table.
Check if the field VOIDR is filled, if it is filled, do not print the amount and date.

How to make the exchange of data between 2 while loop in real time

hello
I have 2 while loop
the 1st while loop includes the data acquisition program
the 2nd while loop includes the control program
my question is how to make the exchange of data between 2 while loop in real time
I tried with the local variable and direct wiring between the 2 while loop
it does not work (there is a delay)
Solved!

Bilalus,
Queues are only good to transfer data if your application isn't deterministic. Since you are using Real Time, I am assuming that your application requires determinism. If you are using Timed Loops and you use queues to transfer data between your loops, you are losing determinism. In this case, you need to use the RT FIFO functions.

How to get the last error for while loop?

How to get the last error for while loop? I just want transfer the last error for while loop, but the program use the shift register shift all error every cycle.

What do you mean by "get" and "transfer"?
If the shift register is not what you want, use a plan tunnel instead.
Typically, programmers are interested in the first, not last, error.
Can you show us your code so we have a better idea what you are trying to?

Usage of for-each loop inside another for-each loop

Hi All,
I have tried using a for-each loop inside another for-each loop as given below.
<?for-each:G_1?>
<Customer Details>
<?for-each:G_2?>
<Address>
<?end for-each?>
<?end for-each?>
Its not getting inside the second loop.I have referred this link
Re: Loop Question but it didn't help me much.Please let me know if am going wrong somewhere.
Regards,
Sudeep.

Sudeep,
The syntax of the for-each statements looks oke. but you have omitted some question marks after the < and before the >.
Furhermore, there cannot be spaces in XML element names. So, "Customer Details" won't work. Change it to something like: "Customer_Details". Also be reminded that the element names are case-sensitive.
try this:
<?for-each:G_1?>
<?Customer_Details?>
<?for-each:G_2?>
<?Address?>
<?end for-each?>
<?end for-each?>
Regards,
Kevin

How to use 'build array' (concatenate) to create a array horizontally?????HELP

I want to link nine arrays whose dimension is 2*2 horizontally，but the function 'build array' (concatenated way) made them vertically.........help me please..........maybe this is too simple.........since I am only a students who learnd labview only few months..
Solved!
Go to Solution.

A transpose operation only solves certain scenarios, but you don't give enough information on what you actually want.
For example, of you have 3 2x2 arrays:
a1 a2 b1 b2 c1 c2
a3 a4 b3 b4 c3 c4
What should the final vertical result be?
a1 a2
a3 a4
b1 b2
b3 b4
c1 c2
c3 c4
or
a1 a3
a2 a4
b1 b3
b2 b4
c1 c3
c2 c4
Or something else?
Please be much more specific. Maybe even attach a small VI containing typical default data.

How to call the 'DETAIL' function in ALV for a program?

Dear Friends,
I have a prf_tree (TYPE REF TO cl_gui_alv_tree), and I added below codes to add an new button for displaying the detail record, it works fine:
CALL METHOD prf_toolbar->add_button
    EXPORTING
      fcode     = prf_tree->mc_fc_detail
      icon      = icon_detail
      butn_type = cntb_btype_button
      text      = ''
      quickinfo = 'Show Details'.
Everytime I click this new button, a window will popup and display the record details.
My question is: how to call this standard function ('DETAIL' function) in a program? for example:
CASE ldf_ok_code.
    WHEN gcf_okcode_save.
      PERFORM okcode_save.
    WHEN 'SHOW_DETAIL'.
      CHECK gdf_nodkey_9003 IS NOT INITIAL.
      PERFORM SHOW_DETAIL.(How to write this code to display the detail data of the selected record?)
Thanks a lot!

How to get an array variable to update in a loop

Hi
I have an array of doubles called cps that contains a double h.
the array is defined out of the loop.
The loop defines the value of h and uses that array to do something. How can I get the array to update h at every iteration of the loop?
// STAR-CCM+ macro: test.java

// CREATING CONSTRAINED PLANE SECTIONS //
Region region_0 =
simulation_0.getRegionManager().getRegion("main domain;main domain;NONE");
Units units_0 =
((Units) simulation_0.getUnitsManager().getObject("m"));
i = 0;
for ( h = 0.5; h <= 2; h = h + 0.5) {
i = i + 1;
ConstrainedPlaneSection constrainedPlaneSection_i =
(ConstrainedPlaneSection) simulation_0.getPartManager().createConstrainedPlaneImplicitPart(new NeoObjectVector(new Object[] {region_0}), new DoubleVector( cps ), units_0); // Sets Plane Boundaries (as mapped) //
LabCoordinateSystem labCoordinateSystem_0 =

constrainedPlaneSection_i.setPresentationName("Unit 1 " + h + "m");
}

double h ;
double[] cps= new double[] {75.9, 52.5, h, 76.5, 49.4, h, // simplifiedLooking at your code I see that you have initialised your array with the value of the variable h scattered throughout it. Are you asking how you can update these "h" values in the array each time around the loop? eg:
Initial array: 75.9, 52.5, 0.0, 76.5, 49.4, 0.0
1st iteration: 75.9, 52.5, 999.999, 76.5, 49.4, 0.0
2nd iteration: 75.9, 52.5, 999.999, 76.5, 49.4, 999.999
Something like that.
If so then you need to know what the indicies of the numbers you want to update which may not be a simple matter. Perhaps an array is not what you want here but maybe a Map instead.
