Closing a form and calling main form's function

[fonix232]

Hey it's me again :)
I will have some more noobish questions today, so prepare yourselves!

So here you go:

In my app when I close a form, I want a menu update script to be ran, because on the other form the user can modify some folders what are present in the menu bar too.

But I can't do that until I change my

public void loadPlugins()

into

public static void loadPlugins()

.

But if I do, some of my commands become invalid.

Here is the code:

public void loadPlugins()
        {
            DirectoryInfo pluginDir = new DirectoryInfo(Application.StartupPath + "//plugins//");
            DirectoryInfo[] plugins = pluginDir.GetDirectories();
            if (plugins.Length == 0)
            {

                ToolStripItem noAddon = pluginsToolStripMenuItem.DropDownItems.Add("[NO ADDONS]");
                noAddon.Enabled = false;
            }
            else
            {

                foreach (DirectoryInfo plugin in plugins)
                {
                    pluginsToolStripMenuItem.DropDownItems.Add(plugin.ToString());

                }

            }
        }

Also the other form's onclose event:

private void PluginManager_FormClosing(object sender, FormClosingEventArgs e)
        {
            MainWindow.loadPlugins();
        }

How could I make this PluginManager form run a function of MainWindow without modifying it's loadPlugins() function?

In your main form, attach an event handler to the close event of your other form.
In that handler, you should be able to call your loadPlugins() function
