I was following along with this tutorial on creating a concurrent counter struct for a usize value: ConcurrentCounter. As I understand it, this wrapper struct allows us to mutate our usize value, with more concise syntax, for example:my_counter.increment(1) vs. my_counter.lock().unwrap().increment(1).

Now in this tutorial our value is of type usize, but what if we wanted to use a f32, i32, or u32 value instead?

I thought that I could do this with generic type arguments:

I am trying to write a macro that will copy from a list of 100 rows (9 cells each) into a single row, then run solver on it, and then copy the values to another spot in the workbook.

The below code works for one line, but everything that i have found online appears to be for paste sequential rows, not copying them and pasting them into the same row to be operated on.

Any help would be greatly appreciated.

Thanks

I am a beginner in Data Science, so please sorry if my mistake is dumb.

Here, I have a loop which views my data frame and makes changes using .loc The problem is that the changes are not saved at the end. I checked every step, everything is processing right. I even checked the modified cell right after working on it (look below) and its gives the value I put into it. However, when the program finishes the my excel data frame is not changed at all.

Help please. Thank you in advance!

I have the wackiest bug. Like....the wackiest! If any of ya'll want to put eyes on this, awesomesauce! I really appriciate it! I am creating a survey with REACT, Redux, SQL, HML, Material-ui, and CSS.

I've created a graph of information with am4charts using data from a database. Everything is working and will show up on the page......but not on page load. What I am seeing in my console is that the page will load, it fires off my get request but doesn't return with the data fast enough (I think). By the time that the get request loads, my graph has populated with no data.

Here is the code that I have for the page that I am rendering. What is really odd is that, once my code has run, I can cut a line of code (I've been using a console log). And then the graph will render and load.

So I want to be able to look at a specific week of the year and look at all data in the preceding and following 6 weeks.

WHERE t1.weeknum >= week-6 AND t1.weeknum <=week+6

So if week is 20, I want to return everything between 14 and 26.

The problem is weeks >=47 and <=6. For instance, if week is 4, I want the range to be 50 through 10. Years are a separate dimension and I am including all data regardless of year.

I think this would be similar to a compass heading. Say you are at 350 degrees and turn right 30 degrees. 350+30 = 20 degree bearing.

I'm using SQL Server Express

I have two select form with submit button, I need to get the result of selected value for example

first select form having colours as an option and second contains another things.

and i have some items as div....red flower , red fish.

if i select red from first form its shows red value div and in second form if i select flower it should display red flower only but it's shows everything under the value red. And these all thing must work only when i submit the search button. I have attached jsfiddle below. Code:

Sorry I don't show my variables or anything, tried to give information only pertaining to the questions. This 1 Sub is huge.

Currently my code allows a user to select multiple files, the files selected will be sorted in a specific format, then loaded into 2 different arrays. Currently loads Columns D:E into 1 array and Columns I:K into another array (from selected files QSResultFileWS, and returns those arrays to my destination FormattingWS. I'm still trying to learn arrays so if the methodology I used to do this isn't proper, be gentle.

I encountered a problem while trying to get my java project running on my Debian 10 server. Everything seems to work, but java throws an error when i try to get an instance of a MessageDigest with "SHA256".

It occurs in this line:

MessageDigest digest = MessageDigest.getInstance("SHA256");

The exception:

java.security.NoSuchAlgorithmException: SHA256 MessageDigest not available

Is there a way to install SHA256 functionality or another way i can create a sha256 hash?

The following code does everything I want: pulls email, saves attachments, extracts files EXCEPT save the original email to the folder fDest. I seem unable to see the solution.

This seems to be the problematic line as it won't save the email: "mi.SaveAs fDest2, olMSG"
