    I don't think this is a good idea. Just share the source code between your 5 different programs. Trying to setup inter process communication will complicate things massively, and probably needlessly. It will also be difficult to maintain the feel of this being one integrated app if you have multiple processes.

    Make a minimal yet complète program that demonstrates the issue. 

     

    Until you isolate the problem by doing this, everything is likely to be a waste of time with irrelevant speculation and guesswork.

    For me, any open source package that I had previously installed via GetIt, I'm now pulling from GitHub.

    I've never understood why anyone would use getit over the main source repo for open source projects

    I am sure that everyone here has everything in duplicate, so when something dies they can replace it in an instance with minimal interruptions, especially if it dies over the weekend during the huge cold spell.

    If I'm running a company like Emba, then I'm not putting production servers on physical hardware with single points of failure.

    Do I need to remind you that on one instance Facebook folks had to literally break into their server room because they got locked out of it. 

    I mean, perhaps there are some incompetent people at Facebook too. I wonder if they learnt from this and changed.

    Nor is there anything unusual about Explorer reading from the files to extract things like file information resources.

    Actually this just looks like what you'd expect to see during process creation. First we check for app compat. We don't find that, fine as you say. And then we map the exe.

    FYI cross posted here (unicode - Delphi - Data is not encoded in given format - Stack Overflow) and with no code there either.

     

    As a rule, I think cross-posting is fine on this site, but you should always note that you've done so to avoid people spending time giving you help when you already received it elsewhere. It's just a good courtesy to the people that you are asking for help.

     

    But in any case, you should improve the post (in both places) by giving details of your code so that we have something concrete.

    You must use GUIDs when there is a need to use RTTI "as" and "is". Like you told, each interface should have a unique GUID, but I have already see that.

     

    Start from here: https://docwiki.embarcadero.com/RADStudio/Alexandria/en/Object_Interfaces_(Delphi)

     

    (may be the link is wrong ... wiki is down at the time of writing)

     

    P.S.: You can read also these books (with examples)

    - Hodges Nick - Coding in Delphi (year 2013)

    - Hodges Nick - More Coding in Delphi  (year 2015)

     

    I don't know if there are something that can help you ...

     

    I think the asker knows what GUIDs are used for. However the question is whether the use of the same GUID for two distinct interfaces is a bug or not.

    It should be; it would spare a lot of headaches when migrating projects to new IDEs.

    I'm struggling to imagine what headaches would be solved by this feature.

     

    I don't know how you can't get a list of generated files by simply checking out the project and then compiling it. All the files created after you compiled are the ones made by that compile.
