Coding questions

[Kira123499]

Hello everyone,

I have a question as a amateur programmer:
I am trying to create a PDF viewer version that always runs in restricted mode, without the restricted control file, i.e. where I can set
‘no internet, no file access and no printing’
directly in the source code.
It doesn't matter whether the PDF is opened by drag & drop or double-click.

The same applies to the settings file. I want to change a few defaults directly in the code and I don't want a settings file to be created.
I've already tried a few things, but I'm not entirely happy with the results.

In the end, I just want a single exe file without any parameter options.
Is this relatively easy to do, or is it a more complex implementation?

As I tried e.g. in sumatraPDF.h the following row
// enables Update checks, crash report submitting and hyperlinks
from
InternetAccess = 1 << 0,
to
InternetAccess = 0 << 0,

and than I can run directly in restriced mode without the argument, the default will be 'no internet' - right?
Thank you very much!
Kira

Hmm I am not the developer but I have seen others do that (Some pirate systems don't want to show their SumatraPDF legacy, so they can charge $100) It often is easy enough for me to bypass their restrictions as a super user because I know the rough attempts to circumvent such restrictions. So you you would potentially need to make some significant changes to the code base to block all external interactions.

I can safely say as a long term user that if you have ALL the restrictions ini settings on I could perhaps still bypass one or two because of how PDF needs wider system access. Yes you can lock down all those by alter code but it may be a slow test process.

Currently the easy way to write a PDF viewer is OLD abandoned PDFiumViewer based on this months PDFium as its one Native Windows CMD compiling one text.cs file using Windows native onboard compiler (not VC / VS) and two small DLLs (one is either older 16MB latest is 26 MB) the other 113 KB from 2017.

So you just write in notepad what you want and no internet required after you fetch the dlls. However build up from scratch is slower than tear-down the full demo but you have full control of functions like 3 page wide or no printing, and don't have to include an open file function.
