data passing

iu2
Hi all,

I need your professional opinion about this. It is more a general
programming dilemma rather then a C++ one, but since the project I
write is in C++...

We handle big structs of data. We also write them to files for use by
other teams.
Here it goes - we use these files also as a means of passing the data
to other stages in our own program.
I wonder if it would be better to pass the data as it is, in structs,
not counting on files.
There is no memory problem.

What do you say?

thanks

I am honestly don't understand what the dilemma is about. You need the
files to interact with some other product[s], fine. But using files
to interact with pieces of your own [running] program? <shrug>

And, yes, 'comp.programmi ng' is probably a better place for a discussion
like this.

Saving data to a file and then reading it in again can never be as fast
as accessing the data directly from memory, nor as easy to do (i.e. more
potential for bugs).

It's a PC program, and the files are read once in a while, so there
are no actual speed limitations.
Using files makes it feel like we are allowed to loosen up interfaces
among modules - no same structs/header files, each module can take
what it needs from the file. This is the main pro, I think.
So what I try to figure out is whether there is a definite "right" way
for data passing (on a PC program with huge available memory). Pros
and cons, may be, from your (and other's) experience?

I feel that using files is not the "right" way for data passing, but I
also don't see why it is "wrong" way...

Hi, In my application I get lots of different sorts of information from databases. As such, a lot of information is stored in DataSets and DataTable objects. Up until now, I have been passing around chunks of data in DataTables/DataSets, simply because that was the format that they were in when the data was taken from the database. Now, I know this maybe a pretty silly question with a standard "it depends" answer, but I'm going to...

In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not.
