I am successfully reading TS classes using ts.createProgram and program.getSourceFile. But when I am reading the class node to list the properties, it doesn't account the properties from the parent class. I can get the symbol and names of the extending classes from node.heritageClauses.

How can I also get the properties list of the parent classes?

I'm trying to separate my input loop from my game logic in my simple snake game that I've made with pygame, but, I'm really struggling to figure out why nothing is happening when I run the program.

I've tried importing pygame in the subprocess, I checked for errors on the subprocess, and got nowhere. I looked on google, but I wasn't able to find any usable examples, or similar issues. Has anybody ever figured any of this stuff out?

Okay, here's the code:

I'm able to insert the customer information but, then I try to insert Reservation information and then I get the error : ORA-02291: integrity constraint violated - parent key not found. I guess my question is do I need to put data in there a order of which table need to have data first? Or is there something else I'm missing? I am still fairly new to SQL this being my first SQl class and any help will be appreciated. Also I will have some parts of the data the same so I want to also know how I can have duplicates in a table.

I have a time-consuming function that I want to run however, I don't want the user to keep waiting. This is my current code:

My html page contains several tables. I implemented a print.css file in order to print correctly the page. One on my table is cut off at the end of the 1st page (because the content is too big for being displayed on this pas). Thus the first page contains only the header of the table at the bottom and the 2nd page contains all the table. Thus the table header is repeated twice.

I would like that the table appears only on the 1st page if one part of the body can be displayed (if the body cannot be partially displayed on the first page, the table with the header should go on the next page).

I tried several css rules but it's not working for my needs:

I am trying to calculate average monthly value of PREMIUM for each POLICY_ID in monthly basis as shown below screenshot. When a customer updates his/her yearly PAYMENT_FREQUENCY to a value different than 12, I need to manually calculate the average monthly value for the PREMIUM. In addition, average monthly PREMIUM amount can be changed in time. For instance, for the POLICY_ID = 1, starting from "2015/11/01" average monthly premium increased from 120 to 240.

How can I achieve the values shown in the column named MONTHLY _PREMIUM_DESIRED?

What I've tried:

I just found this thread with the same question but in C#.
How do you achieve this in C? Is there a better solution than using a loop until it reaches EOF like this or is there already a function in the libs which can do this?

The codde below is the function check which is a condition function where the function save_user() has to be excecuted only these all conditions are satisfied
