Binario | Responsive card-based & code-light Hugo theme | Theme library

what's up friends, I got the issue of the title, programm working with 3 QLineEdit where 1st it's to introduce a decimal number, 2nd a hex, and the 3rd a binary.

I got signals that works while I introduce a decimal number then it puts the hex value in the 2nd QLineEdit(it's converted by signal) , and to the same way for the binary value.

until here, before was working(but not now), after I put a code to introduce a binary or hex, then it becomes to decimal , and the other val...

I need your help, maybe I'm not seeing something .... it's literally the first time I used QGidLayout, etc etc.

I'm trying to make a calculator where people have different choices, based on numbers.

When I put in a choice that is not an int, it throws a InputMismatchException, but for some reason it won't be caught.

Here is the code I have so far:

I have a problem when passing a string to a file. I am almost sure that the problem comes from the way I read the variable, and so I leave the piece of code that I think is wrong. If you don't think the problem could come from there, I reassess the situation and send what I think is necessary.

I don't understand my problem because the system is actually saving something, but for example when I enter 5 teams, the system only registers 2 or 3 teams in the file. Does anyone know what this is about?

Here is the code:

My struct:

I am writing you because I am trying to create two columns:

data_i: With the value of the column "precio_actual" of the first spark streaming window

data_f: With the last value of the column "precio_actual" of the window,

for example now what I have is the following:

I have an application in Delphi 7, where I made the code below to load large PDF files from a blob field to memory and then I load the PDF, it works perfect with large files I have already tested with 1 gigabyte files. However, somewhere there is a memory leak and I don't know where, after loading 10 large files, it presents the Message - Out of Memory.

I am not sure how to clear the memory after loading the memory.

I already tested loading several pdf files and it works perfectly, the component has no problem. Note guys, I don't want to save it to file after loading it in the component, I want to do it directly in memory.

Note guys, I don't want to save to file on disk and then load the component, I want to do it directly in memory.

I'm trying to write a F# query as follows

I'm trying to make a forecast of a arima with regression (Regression with ARIMA errors) to several ts at the same time and using grouped data.

I'm new in the tidy data so... Basically, I'm reproducing this example (https://cran.rstudio.com/web/packages/sweep/vignettes/SW01_Forecasting_Time_Series_Groups.html) with a multivariate ts, and multivariate model.

here is a reproducible example:

I'm trying to use Indy's IdFTP to send and receive some files via FTP.

I'm a complete newbie to C++ programming. I've been given the task to code decimal to hexadecimal,octal,binary conversion.I have encountered errors in the "binario" function, when I enter a decimal number greater than 1000 the function gives me a result as a nonsense random numbers.
