How to remove only the last element of spreadsheet string

I use path to string option to store image path into database and while retrieving the string is again converted into path but it gives out an error as the output of array to spreadsheet string gives out a tab at the end which is unable for the IMAQ read file to recognise.but when i use the path of the image directly into IMAQ readfile the image is opened . so how to remove the tab only at the end of output of the spreadsheet string(whose length can vary)? I have also attached my program with this.

If you just want to remove the last character of a string just use the
String Size function reduce the result by one and wire it together with
the string to the Split String function.

How we can find the last character in a string(Urgent Plz!)

Gurus!
How we can find the last character in a string.

Now i want to find the last character in "Str" i.e "ONE=1".

Use the substr() and length() functions -

y := substr(x, length(x));

How to select the last elements in a string

Hi Guys
I am using UART RS232 protocol and i need to calculate the check sum. My data came in decimal and in the end it must be doubles to manipulate it. So my problem is, for example, the sum of all elemants is in decimal 1742 and in hex is 6CE and i wont only the last two elemants, CE that corresponds to 206 that is the result of my checksum. Can anyone help me?
Thanks
Solved!

Thanks Syrpimp
My data came from HMI in decimal like the example that i show above. Each cell is a value. You used an array, but i think that i can't use it because it must be done automatically and the data field have variable length.
The UART protocol frame has a start frame field that corresponds to two ‘{‘ characters and an end frame field that corresponds to two ‘}’. Additionally, besides the data field, that has variable length, it has a byte that corresponds to the command type and another that is the checksum. The following table illustrates the protocol.

WebService problem: only the first element of a string array is returned

Hello,
i did the J2EE QuickCarRental tutorial and extended it by some features: I created another entity bean and implemented four new methods in the QuickOrderProcessor. Then i deployed it as a WebService and accessed it using the Visual Composer.
Everything works fine except the return value of one WebService method. I created a method with the return value String[]. But the Visual Composer reads it as String. Only the first element of the resulting string array is displayed. Although the test at the web-page http://<server>:<port>/QuickCarRentalService/Config1 displays the whole string array with all its elements. What did i wrong?
Another problem is that after deploying the J2EE-Application with new WebService methods the changes are not visible inside the visual composer. Although the test at the web-page http://<server>:<port>/QuickCarRentalService/Config1 displays the changes. Do i have to restart the WebService system in the portal content? If yes how can i do that?

Here are details about setting up and using web services and some examples:

How can I remove only the middle elements from a 2-D array?

Hello all!
We have had an issue at my work where some of our graphs featuring a Gaussian curve have an unusual rectangular distortion in the middle of the curve (sorry that I have no image to show you, the error is before my time at the company, and I've been asked to find a solution before it happens again). Basically, what should be a Gaussian curve is leveling off briefly and looking like a rounded square wave. We know what causes the distortion, so I only wish to remove the middle part, giving it the appearance of a Gaussian. It's odd, but it actually offers a good approximation of what we want. The graph is made from a 2-D array of Double values, and we can estimate the size of the leveled-area, so I figured that removing the middle elements from the graph would accomplish this. Does anybody know a way I can accomplish this?

How to get only the last part of the URL in the doGet() method?

In the doGet() method is there a way to check what URL it was called from ? For example the URL was: http://localhost:8080/myproject/jsp/randomPhrase.php (the php here is purely for misleading purposes - it's all Java really). in the doGet() method I would like to get the "randomPhrase" part of the URL only - to determine where to redirect the user. How can I do that?
Thanks.

Hello there,
As it seems to me the part of the URL you're looking fo,r corresponds actually to the name of the servlet, so why don't you just call the getServletName method?

How to get the last element of a structure in a textfield in DesignStudio

Hello,
how can I get the last element of a structure within a bex query?
Within the structure we are working with dates that dynamically are buiId (input date - offsets for several months).
I have to show the last value in a single textfield within DesignStudio.
Regards
Frank

Hi Frank,
in DS 1.3 you can use forEach function to get the last element of BEx structure (or n-th element in general using if condition)
var array = DS_CROSSTAB1.getMembers("DHGY5D6XEFO1K45SB00BXFH7A",10);
var lastMember="";
array.forEach(function(element, index) {
lastMember = element.text;
TEXT_1.setText("Last structure element: "+lastMember);

How to get the only the last raw of the table

Hello All,
While fetching a table into internal table, how to get only the last record of the table.?
Thanks and Regards, Pradeep

I hope following code will solve your problem.
DATA : it_bseg TYPE TABLE OF bseg,
x_bseg TYPE bseg,
v_index TYPE i.
SELECT COUNT(*)
FROM bseg
INTO v_index.
SELECT *
FROM bseg
INTO TABLE it_bseg.
READ TABLE it_bseg INTO x_bseg INDEX V_INDEX.
First SELECT will give you the number of rows in a table in v_index. Second SELECT will fetch all table data and then READ will give you the last record of the table in a structure x_bseg.
Reward points if the answer is helpful.

How to get only the first result in extract function

do you know how to get only the first element of the function extract.

if i have 5 responses like '100','100',100','200','200' e get '100100100200200' and i want only '100'.
thanks in advance

Two ways .....
1. Use Javascript E4X instead ...there are nice functions for getting children of parents.
2. Cycle through all of the form1.nodes and look for objects that have a className of "subform". For loops are useful for this task.
Make sense?

replace string+lv_count_last(lv_count) in string by ' '.
This should work.

How to delete the last element of a collection without iterating it?

how to delete the last element of a collection without iterating it?

To add to jverd's reply, even if you could determine the last element, in some collections it is not guaranteed to always be the same.
From HashSet:
It makes no guarantees as to the iteration order of the set; in particular, it does not guarantee that the order will remain constant over time.

HT4075 I don't have any problems merging the documents by dragging, but when I try to save and open afterwards, only the last shown doc was saved, not the combined files I wanted to merge. I tried save and export, how can I create the file after merging?

Hi, I'm having trouble saving the documents when merging in Preview. I don't have any problems merging the pdf documents by dragging them in preview, but when I try to save and open afterwards, only the last shown doc was saved, not the combined files I wanted to merge. I've tried save and export, but none merge the documents after saving... how can I create the file (with all the pdf files) after merging?

That's a comment in the file. It has no effect at all.

Find My iPhone only keeps a history of locations after you put it in lost mode. It also has to be online to provide an updated location.
