Ahh. What would I use if not the hashset for the static data then? The tolower trim was to normalize the input, but that's gone now as I switched to using an enum for the permission nodes rather than typing them as strings. Roles are variable, users can add them. Thanks!

How do you kill off left padding/margin in DataGridView headers?
Of course, now that I think about it, this was a few years ago and since then I've bought a new rig; Core i7-13700K 3.4ghz, 128GB DDR4-3200, Samsung 990 Pro M.2 SSD so maybe I should try again. I can't imagine how VS could lag that, lol

I installed 20... 22? i think it was at one point and it seemed really laggy. Like intellisense would take a couple seconds to update, it was frustrating. 2017 is lightning fast, so I just went back to it. Some day I'll hit a wall where I need newer than .NET 4.8 and that will force me to upgrade, but haven't hit it yet hehe.

public static class Perm {
  private static Dictionary<Guid, HashSet<string>> Permissions = new Dictionary<Guid, HashSet<string>>();
  private static Dictionary<string, HashSet<string>> Inheritance = new Dictionary<string, HashSet<string>>();

  public static void Init() {
    foreach (User user in DataManager.GetUsers()) {
      Permissions[user.Id] = DataManager.GetUserPermissionSet(user.Id);
    }
    Inheritance = DataManager.GetInheritanceSet();
  }

  public static bool Has(string node, Guid id = default(Guid)) {
    if (string.IsNullOrEmpty(node)) return false;
    node = node.ToLower().Trim();

    if (id == Guid.Empty) {
      if (cfg.LoggedInUser == Guid.Empty) return false;
      id = cfg.LoggedInUser;
    }

    if (!Permissions.ContainsKey(id)) return false;
    if (Permissions[id].Contains("administrator") || Permissions[id].Contains(node)) return true;
    if (!Inheritance.ContainsKey(node)) return false;

    return Inheritance[node].Any(x => Permissions[id].Contains(x));
  }
}
public static class Perm {
  private static Dictionary<Guid, HashSet<string>> Permissions = new Dictionary<Guid, HashSet<string>>();
  private static Dictionary<string, HashSet<string>> Inheritance = new Dictionary<string, HashSet<string>>();

  public static void Init() {
    foreach (User user in DataManager.GetUsers()) {
      Permissions[user.Id] = DataManager.GetUserPermissionSet(user.Id);
    }
    Inheritance = DataManager.GetInheritanceSet();
  }

  public static bool Has(string node, Guid id = default(Guid)) {
    if (string.IsNullOrEmpty(node)) return false;
    node = node.ToLower().Trim();

    if (id == Guid.Empty) {
      if (cfg.LoggedInUser == Guid.Empty) return false;
      id = cfg.LoggedInUser;
    }

    if (!Permissions.ContainsKey(id)) return false;
    if (Permissions[id].Contains("administrator") || Permissions[id].Contains(node)) return true;
    if (!Inheritance.ContainsKey(node)) return false;

    return Inheritance[node].Any(x => Permissions[id].Contains(x));
  }
}
GetInheritanceSet returns a HashSet with all the nodes that would grant the key node, like 
Dictionary<string, HashSet<string>> {
  { "game.view", new HashSet<string>() {
      "game.edit",
      "game.delete",
      "game.launch"
    }
  },
  { "game.edit", new HashSet<string>() {
      "game.delete"
    }
  }
};
Dictionary<string, HashSet<string>> {
  { "game.view", new HashSet<string>() {
      "game.edit",
      "game.delete",
      "game.launch"
    }
  },
  { "game.edit", new HashSet<string>() {
      "game.delete"
    }
  }
};
So if I do Has("Game.View") and the user doesn't explicitly have that but they do have Game.Launch, it would return true. Does that look workable?

I have a followup question. I'm working on implementing this. I have a static Perm class now, with a private Dictionary<Guid, HashSet<string>> Permissions. I have an Init method that populates the dict with the user's ID's then all the nodes to which they have permission. Then I have: 
public static bool Has(string node, Guid id = default(Guid)) {
  if (string.IsNullOrEmpty(node)) return false;
  if (id == Guid.Empty) {
    if (cfg.LoggedInUser == Guid.Empty) return false;
    id = cfg.LoggedInUser;
  }
  if (!Permissions.ContainsKey(id)) return false;

  return Permissions[id].Contains("administrator") || Permissions[id].Contains(node).ToLower().Trim();
}
public static bool Has(string node, Guid id = default(Guid)) {
  if (string.IsNullOrEmpty(node)) return false;
  if (id == Guid.Empty) {
    if (cfg.LoggedInUser == Guid.Empty) return false;
    id = cfg.LoggedInUser;
  }
  if (!Permissions.ContainsKey(id)) return false;

  return Permissions[id].Contains("administrator") || Permissions[id].Contains(node).ToLower().Trim();
}
But I'd like to support inheritance. Like If I have nodes like: 
Game.View
Game.Edit
Game.Delete
Game.Launch
Game.View
Game.Edit
Game.Delete
Game.Launch
If I'm checking for Game.View, then if they have edit, delete or launch it stands to reason that view is a given. What would be a good way to handle that?

Hmm I could keep a cache in the perm manager and when an admin changes ppls perms, flush cache and/or flush it every X minutes that may reduce load.

Roundtripping to MySQL that much won't be an issue? Well, it's not like I'm making some high use app anyway lol so I doubt it'd be an issue. Just curious.

So like when I do a permission check, just have a method that does like SELECT index FROM permissions WHERE uid = ?uid AND permcode = ?perm Then pass the user Guid and maybe a string like "game.delete" then if a row is returned, I know they're authorized else deny?

Control getting resized when adding to FlowLayoutPanel
The behavior I was expecting was just for it to add my UserControl with the data populated, and not adjust the UC's width. I wasn't sure why the width would get fiddled with. As to why a FLP, I need to add a variable amount of controls to the form and have it scrollable. I wasn't sure there was a better way than a FLP?
