How to find the elements of an array

I want to find the number of elements in an array, and I can't find the tutorial that shows how to find it. If anyone could point me in the right direction, it would be greatly appreciated.

Depends upon your interpretation of "number of elements in the array"
int[] numbers = new int[10];
numbers[0] = 42;
numbers[1] = 666;Number of elements in the array is 2 not 10.
</pbs>If you used something other than a primitive type for the array element type you could have a case. A value of integer zero for the other elements is still a value, so there are indeed 10 elements there.Even if it were not primitive, every element would have a value. That value would either be null or a reference.

Basically it is (at least in LV8.0). There is a property "Number of Rows" which sets the number of visible rows. If your 1D array is placed horizontally, use "Number of Columns".

How to find the elements in the UI panel.

Hello,
I have a UI panel from a plugin. I just need to automate it, like setting the text in the text box and clicking a button in the panel. For eg application.activeDcoument.swatches will bring in the swatches panel. Similarly i can able to call my panel using the adobe ID. But i cant able to set the elements inside the panel. Plz help. Thanks in advance.

No it does not.
Ask the plugin supplier how to access its function through a script. And don't be too surprised when you are told it doesn't support scripting.

How to find the mode of an array of strings

Hey guys,
So I came across this little problem that I thought I could solve relatively easily, but it turned out quite messy.
I have this array of strings and I want to find the most frequent entry of that array. Let's say I have the following array.
apple
apple
kiwi
orange
apple
the mode would give me apple. I thought about converting the strings into a number and then find the mode as usual.
But if the string was too long, it seems a single number cant be used to represent it.
Any ideas on a clean way to do this?
Solved!

This may work also
You should probably link to the thread where this solution was first presented instead.
Since the question was: "I have this array of strings and I want to find the most frequent entry of that array", here's is a more tailored solution to the actual question.
Still, my more traditional approach outlined in the first answer would probably be more efficient, because it does not generate any large data structures. Try it!

How to randomize the elements in an array!!

Hi,
If i have an array, with say 50 integers which may be in some kind of order, is there a special method which could randomize these numbers for me? If not does anyone know of an algorithm which could do this?
Many thanks
Cath

Hi,
You could do that this way:
int data[] = new int[50];
for (int i=0; i<50;i++) {
data[i] = (int)(Math.random() * 100);
This code generates a random number between 0 and 1 and multiplies it by 100. This way, the resulting number will be between 0 and 100. If you want another order of data, you could multiply the ramdomly generated number by the greatest value you are expecting to be generated.

How can I find the element with the closest value to a calculated "target value" in a 1D array?

Hello all,
may be the following question is very simple, but I am relatively new in labview and it would be great if somebody could help me:
I have a acquaried 1D array of data-points. Now, I have to find the element in this array which value is the closest to a calculated "target value".
After finding the element with the value close to the "target value", I have to get the position of this element (i.e. the index) in the 1D array.
Now, I have to use this index to find and extract the element at this position in an other 1D array.
It would be very nice if somebody could help me with this problem.
Thank you,
beam

How to find the nearlest value in 1-D array ?

Hi.. everybody..
I need to seperate the raw data(1-D) into 2 group of array by the center value and then make the average value in each array. But I also still have the problem about if the center value is not the same of some value in the 1-D array. I cannot use the split function.
"How to find the nearlest value to the center point that I calculated, in the 1-D array ?"
Thanks a lot for anybody help

In a general sense, since I'm not sure what your data values are or how far away your calculated center is from the true value, I would do it one of two ways:
1) Use a threshold value and scan the array until the threshold is reached (assumes constantly increasing values in the array).
2) Use either a) round to nearest integer b) round to + Infinity (round up) or c) round to - infinity (round down). If you don't have decimal values, you'll have to devide the values by a power of 10.

How to find the WBS element for the payment document?

Dear All,
How to find the WBS element in the payment document?...I know in payment doc there will not be any WBS but is there any option where I can find in any of the Tables.
I am in the process of developing a Z report where i need to fetch the payment documents based on WBS. Can any one please help me on this.

Hi Ram,
As you are not giving any input of WBS at the time of payment you cannot fetch this directly. But to know the WBS for the reporting purpose on which WBS the payment has been made, you can develop a Z-Report. The WBS elements of clearing documents against the payment entry can be fetched out.
In this report if there is a single payment against many invoices also possible with different invoice and WBS elements to be displayed on the Z-Report

How to find the number of data items in a file written with ArryToFile function?

I have written an array of number in 2 column groups to a file using the LabWindows/CVI function ArrayToFile...Now if I want to read the file with FileToArray Function then how do I know the number of items in the file. during the write time I know how many array items to write. but suppose I want the file to read at some later time then How to find the number of items in the file,So that I can read the exact number and present it. Thanks to all
If you are young work to Learn, not to earn.
Solved!
Go to Solution.

What about:
OpenFile ( your file );
cnt = 0;
while ((br = ReadLine ( ... )) != -2) {
if (br == -1) {
// I/O error: handle it!
break;
cnt++;
CloseFile ( ... );
There are some ways to improve performance of this code, but if you are not reading thousands of lines it's quite fast.
After this part you can dimension the array to pass to FileToArray... unless you want to read it yourself since you already have it open!

How to find the table in which data from a structure sits

Hi,
I want to know how to find the exact table where data sitting in various structures during runtime are stored.
For instance,in ME23N we have various tabs and data in those are held in various structures. This we can see by checking the technical setting of each field.
I want to know in which table the data is actually stored for each field and how to find them.
Any other means other than using "WHERE USED" option?
Thanks
CM

After checking for technical field from the screen, when you reach out to structure, you can dbl click on the particular field's data element. From this data-element you can get to know in which tables it is used. Also if the data element refers to some master data field then you can check out its domain and in the domain you can refer the<b> value table</b> for that domain. This is what i will do if i am not sure about anything.
Hope it will help a little.

How to find the list of Queries/Reports which are using Exceptional Aggregation in SAP BI?

Hi All,
We are interested to know how to find the list of Queries/ Reports which are using Exceptional aggregation in SAP BI.
Please let us know is there any table's to check the list of reports using Exceptional Aggregation in SAP BI.

Hi,
Here you go..
1) Go to table RSZCALC and get list of ELTUID where AGGREXC is not INITIAL and AGGRCHA is not initial; now you get only exception aggregation set based on some chars. Also you can further add STEPNR = 1 since your intention is just to get query name , not the calculation details; this will reduce number of entries to lookup and save DB time for next steps.
Here you will get list of exception aggregation UUID numbers from which you can get properties from RSZELTDIR.
2) Pass list of RSZCALC-ELTUID to table RSZELTXREF - TELTUID and get list of RSZELTXREF -SELTUID - this table stores query to it's elements maping kind.
3) Now again pass RSZELTXREF - SELTUID into same table but into different field RSZELTZREF - TELTUID and get RSZELTXREF - SELTUID
This step you get query reference sheet or column or query general UUID for next step.
4) Pass list of RSZELTXREF - SELTUID into RSZELTDIR - ELTUID with DEFTP as 'REP'. Now you get list of query names in RSZELTDIR - MAPNAME and description in TXTLG.
Note: you can also get the reference chars used for exception aggregation from RSZCALC - AGGRCHA field.
Hope this helps.
Please keep in mind, it might take more time depends on how many query elements you have in the system...

How to find the most matched values in the set of map?

Hi friends!
I have two vectors
vector<int> V1; vector<int> V2;
and a map<int, set<int>> M1;
I want to select common values from both V1 and V2 and check those values with the set in the map M1.
For example:
V1 contains;
2 4 6 8 9
V2 contains;
4 5 6 9 10
M1 contains;
1=>1 2 5 9
2=>4
3=>5 10
4=>2 4 8
5=>4 9
6=>4 6
7=>9 12
When we select the common values of V1 and V2 it is 4, 6, 9.
And we search for all 4, 6, 9 from the values of M1 which give more appropriate.
But, no all values in the set of map.
Then, we delete any value from 4, 6, 9, then remaining values would match any values from the map.
From the example, if we delete 6, then remaining 4, 9 will match with 5=>4 9, or if we delete 9, then 6=>4 6. Any one of the keys can be selected.
I know how to select the common values from V1 and V2, but I do not know how to match with the values and select the appropriate key from M1.
Could anyone help me to solve this?

This is not the question you asked, except perhaps in the subject. The subject is not the right place to put key features of the question. It is also important to use the body to ask just the question you want
answered. For example your real question has nothing to do with V1 and V2, just the common vector V (e.g. 4 6 9).
One way to solve your problem would be to create a new map
map<int, set<int>> M2;
with the same keys as M1. Each set of M2 should contain the elements of V that are
not in the corresponding set of M1.
Then pick the key of M2 that has the smallest set. If that set is empty, then the whole of V can be used. Otherwise the smallest set tells which elements of V have to be removed, and which is the desired key of M1.
In your example, key 5 of M2 will contain just 6, so you should remove 6 from V and select key 5.
Yes fine. I tried the following code and it creates the map M2 (NewMyMap in my code). But how to find the smallest set starting from size 1?

I own both Photoshop Elements and Photoshop (the original editor). I find the elements editor to be too cumbersome to use and would just like to edit using Photoshop. When I try to install Photoshop as a secondary editor in elements I get an error message that I don't need to this because it is already supported on the edit menu and task bar. I can not find any way to send images to Photoshop for editing - all I can do is send them to elements editor or the premier editor. Can someone tell me how to send them to Photoshop? Thanks!

Hi,
The D810 requires Camera Raw 8.6 or later - the latest version that is compatible with Photoshop Elements 12 is Camera Raw 8.5 as far as I can see.
You need to either buy a new version of Photoshop Elements or use the free Adobe DNG converter.

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.
Cheers. Keith.
