QUESTION
I was trying to check if the username entered is equal to the second index of item in the list, and I tried to use !=, but it still keeps letting the same username to be registered. What's the problem with the code ?

Answered 2021-Jun-03 at 01:49This code below will sort a lot of things out. In your code, even if we fix the indentation mistake with the else which should be moved into the for loop, the code won't work if we type Raymond
. So I have provided an example which checks if the entered usr is in all the names in your user_list
.

I would like to display a data from .txt report file using JavaFX. In my code, I'm trying to use Labels and Vbox to display the info in multiple formats in a GUI to scene. However, I'm having terrible outputting my results as GUI instead of the console. I tried to research my issue but I couldn't find the piece of info that I need to solve the problem.

QUESTION
Considering the following SO Question: Is it dangerous to use synchronize in a non-VCL application?
I was wondering how TThread's Synchronize
, CheckSynchronize
and WaitFor
is affected when using them inside an Apache Web Application DLL.
I started investigating this when I realized WaitFor
was locking/hanging. Inside WaitFor
it checks if CurrentThread.ThreadID = MainThreadID
and then repeats checking the result of MsgWaitForMultipleObjects
and based on the result it will do CheckSynchronize
or PeekMessage
and when it received a WAIT_OBJECT_0
it will finally exit the loop. If the MainThreadID
is not the same as the CurrentThreadID
, then WaitFor
will do a single WaitForSingleObject
.
So I created the following test Apache Web Module DLL to see what the MainThreadID
is during the lifetime of a web request.

Answered 2021-May-11 at 11:02To recap:
A DLL's DLLMain/DLLProc
is called whenever a process is "attached/detached" and a thread is "attached/detached"
There is also a blog post by Raymond Chen that discusses thread deadlocks in DLLMain
.
Because DLLMain
is called when the the DLL is unloaded and also when a thread exits I cannot do a thread WaitFor
in the DLL Unloading code (OnWebModuleDestroy
) as that will obviously cause a deadlock as the one will be waiting for the other.
After R.Hoek's comment I started looking to see if Apache calls some sort of cleanup procedure before it actually unloads the module DLL and came upon its apr_pool_cleanup
and the companion apr_pool_cleanup_register
procedure which registers a hook into the the cleanup. Fortunately this has already been handled inside the Web.ApacheApp
unit and its TApacheApplication
class that has an OnTerminate
"event" which is called by the apr_pool_cleanup
.
Assigning cleanup code to the OnTerminate
"event" allows you to properly get rid of your threads without fear of deadlocks in DLLMain

QUESTION
I have a question that sorts data from a car report of txt file.
The question is: How do I listed cars sorted by their MAKE (Ford, Chevy ..etc). They only need the MAKE to be sorted so they can be all FORD cars under each other, then Chevy, DODGE .. so on and so forth like this:

QUESTION
I have a Java question that deals with reading the txt file and pulling data from it.
It's a bunch of used cars stored in a txt report file. They have several different lots that they sell from. The lots are identified by the 5 digit zip code followed by a zip code extension at the beginning of each record. They would like a report that lists all cars sold from all lots. This is what I come up with:
They would like the report to list 30 cars per page, on the report. Each page is to have headings and a page number. Like this:
My question is how do I list 30 cars per page instead of all together (Each page 30 cars with headings and page #)?
Here's my source code:
...ANSWER
Answered 2021-Apr-29 at 12:44As I already stated in my comment you'd need to count the cars you've already processed and print new page headers when you've hit a multiple of 30 cars.
First I'd suggest moving your header print statements to a separate method, e.g. printPageHeader(int pageNumber)
. Then change your loop like this:
