Hi there,

I just did a quick check by simply adding a little code to one of my plugins like this:

var controller = SdlTradosStudio.Application.GetController<ProjectsController>();
var cur = controller.CurrentProject;
var sel = controller.SelectedProjects.FirstOrDefault();
var curname = cur != null ? cur.GetProjectInfo().Name : "NULL";
var selname = sel != null ? sel.GetProjectInfo().Name : "NULL";

MessageBox.Show($"Current project: {curname}\r\nSelected: {selname}");

Then I double clicked one project in the projects list to make it bold and current. I double clicked to open files view, then opened that file in editor.

Then I triggered my code from projects view, from files view, and from editor. In all cases it always showed me the one bold formatted project, whose file is displayed in the files view as well as in the editor as "Current" and any project that I had selected by single clicking it in the projects view as the "Selected". When I had not selected any (click in an empty area in projectlist to clear selection) it displayed my current project as usual and NULL for selected project.

So, yes, there is a clear distinction, and yes, you can rely on it pretty well.

Hope this helps.

I appreciate the offer. Let's see if I can snip the relevant portion of the code.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using Sdl.LanguagePlatform.Core;
using Sdl.LanguagePlatform.TranslationMemory;
using Sdl.LanguagePlatform.TranslationMemoryApi;
using Sdl.ProjectAutomation.Core;
using Sdl.ProjectAutomation.FileBased;
using Sdl.TranslationStudioAutomation.IntegrationApi;

namespace MySDLPlugin
{
    [TranslationProviderWinFormsUi(Id = "Translation_Provider_Plug_inWinFormsUI",
                                   Name = "Translation_Provider_Plug_inWinFormsUI",
                                   Description = "Translation_Provider_Plug_inWinFormsUI")]
    class MyTranslationProviderWinFormsUI : ITranslationProviderWinFormsUI
    {

        public ITranslationProvider[] Browse(IWin32Window owner, LanguagePair[] languagePairs, ITranslationProviderCredentialStore credentialStore)
        {
                    ProjectsController c = SdlTradosStudio.Application.GetController<ProjectsController>();

            // Method A: use reflection to coerce the "owner" to yield the
            // title of the dialog, and use it to match the name of the project.

            dynamic tlc = owner.GetType().GetProperty("TopLevelControl").GetValue(owner);
            String tlTitle = (String) tlc.GetType().GetProperty("Title").GetValue(tlc);

            FileBasedProject selectedProject = null;
            TranslationProviderConfiguration tpc = null;

            foreach (FileBasedProject pr in c.GetAllProjects())
            {
                string pName = pr.GetProjectInfo().Name;
                if ("Project Settings - " + pName == tlTitle)
                {
                    selectedProject = pr;
                    tpc = selectedProject.GetTranslationProviderConfiguration();
                    break;
                }
            }
            // Method B: use the current or selected projects.
            tpc = c.SelectedProjects.First().GetTranslationProviderConfiguration(); // or
            tpc = c.CurrentProject.GetTranslationProviderConfiguration();
            ...
        }
    }
}

Method A works, but it's horrid and undocumented and I can't believe it's the only way to do it. Method B will reliably get the configuration of the selected project, if there is one (and there isn't always one), or the configuration of the current project, if there is one (and there isn't always one). And if there are both a CurrentProject and a SelectedProjects list of length 1, there's no way to know which one the Browse() method was invoked for, because, as I noted, in the situation where there is both a current/active project and a single selected project in the Projects view that isn't the active one, both CurrentProject and SelectedProjects will be populated and the Project Settings button in the ribbon will edit the CurrentProject if you're in the Files view and the single element in SelectedProjects if you're in the Projects view.

Thanks for your attention.

I've tried but failed.
I do not know how to use Browse instance ('owner' part).

Feels like a waste of time.
Nothings unclear here. But, it is sucks clearly.
Project Settings Configuration Icon do sucks.

If you want to use that pop up, you must select a single "Selected project" strictly at Projects View.
If you have "2 or more Selected  projects" or "0 Selected project" it goes to InActive at Projects View.

You have to know different rule for Files View and Editor View.
In these views, selection does not matter at all.
It show you "Current/Active project" all the time.
