QUESTION
I have to paste the value of variable $val in cell 'B3' in Sheet 0. After this, I have to export sheet1 as pdf.
But I can see that when I am converting sheet1 as pdf, the formulas are not printed 'as values' but they are printed as a string.
Moreover, 0's are getting populated in empty cells. Attaching screenshot of the same.
...ANSWER
Answered 2021-Jun-15 at 17:13The auto-population of 0 in empty cells was solved by simply opening excel-> Click on file-> Options -> Advanced -> de-select the checkbox containing "Show a zero in cells that have zero value. And for formula, you need to make sure that all cells involved in, should be of same format. Click on cell then right click, then select format and cross check the if format are same.
QUESTION
I'm trying to understand how the "fetch" phase of the CPU pipeline interacts with memory.
Let's say I have these instructions:
...ANSWER
Answered 2021-Jun-15 at 16:34It varies between implementations, but generally, this is managed by the cache coherency protocol of the multiprocessor. In simplest terms, what happens is that when CPU1 writes to a memory location, that location will be invalidated in every other cache in the system. So that write will invalidate the line in CPU2's instruction cache as well as any (partially) decoded instructions in CPU2's uop cache (if it has such a thing). So when CPU2 goes to fetch/execute the next instruction, all those caches will miss and it will stall while things are refetched. Depending on the cache coherency protocol, that may involve waiting for the write to get to memory, or may fetch the modified data directly from CPU1's dcache, or things might go via some shared cache.

I need to generate a list of dates in a dataframe by days and that each day is a row in the new dataframe, taking into account the start date and the end date of each record.
Input Dataframe:

this code returns me a black screen, what am I doing wrong?
python file:
...ANSWER
Answered 2021-Jun-15 at 01:11The problem is that the kv
language insists that class names start with a capital letter. The documentation says:
Keep class names capitalized to avoid syntax errors
I think your code will work if you change all your class names to meet that requirement.

QUESTION
I need to prevent duplicate entries in each row ,But in the same time two possible values can be entered into each cell "Yes" or "No".I used this formula in data validation =COUNTIF($B3:$J3,B3)=1 and applied to subsequent rows. The issue now , I need these range of cells accept "Yes" or "No" only by using any means even vba.
this link for the sample sheet: https://easyupload.io/f4sjf3
...ANSWER
Answered 2021-Jun-14 at 16:17To allow only "Yes" and "No", you can set up a simple validation rule (as List).
. Depending on the settings of your computer, you will have to change the ";" in "Yes";"No"
into a comma.
To ensure that only one "Yes" is entered per row, you could use the Worksheet_Change Trigger: Put the following code into the Worksheet Module of the according sheet:
QUESTION
I have put example dataset (df), expected output (df2) and my code so far below. I have a df where some rows in column i2 contain a list - in the json format, which need exploding and reinserting back into the df, from the row in which they were extracted. But the need to be inputted into a different column (i1). i need to extract a unique identifier (the 'id_2' value) from the string and insert that into the id_2 column.
in my code so far i am parsing the json-like data with pd.normalize, and then inserting the original string from the column i1 onto the top of the extracted strings (it should be much more clear if you take a look below) and then reinsert them based on the index. But I have to specify the index, which is not good. I would like it to be less dependent on manual input of indices in case it changes in the future with more of these nested cells or somehow the index changes.
Any suggestions are very welcome, thanks so much

QUESTION
I'm a programming newbie so please bear with me.
I currently have a sheet, Sheet1 "DataSheet", holding string (text) data over an undefined amount of rows in Columns A, B and C. Sheet2 "BlankSheet" is a template "Score Card" which I must duplicate indefinitely based on total rows of data entry in "DataSheet". I did this using a command button.
...ANSWER
Answered 2021-Jun-14 at 12:50This code should do everything in one subroutine and can be called from an individual button.

How can I refer in VBA to a previously newly created workbook within the same macro? For example, I copy something from A2 in the active workbook, then I create a new workbook, paste there in cell B3, return to the first workbook, copy cell A3, return again to the newly created workbook and paste in in cell B4.
So, what I need is the code for this part of the sentence: "return again to the newly created workbook"
My code till now is this:

I made a little program to generate random musical notes. I am getting the following error:
Exception in thread "main" java.lang.NullPointerException: Cannot invoke "java.util.ArrayList.add(Object)" because ".llaveFa" is null at sollasidore_14_9.main(sollasidore_14_9.java:99)

The code is:
...ANSWER
Answered 2021-Jun-14 at 00:52The error in this line llaveObj.llaveFa.add(randomNum);
coming from llaveFa
is not initialized. Let me explain this, in "Nota" class you are declaring in this line ArrayList llaveSol, llaveFa;
llaveFa and llaveSol are initialized with null, to fix this you can initialize the variables right in the class itself with something like that:
ArrayList llaveFa = new ArrayList();
