Usage

Dark Mode can be enabled for your project in 2 easy steps:

Step 1: Enabling dark mode for your application

1. Add a reference to the DarkMode.dll assembly in your application.
2. Go to your project properties, and click View Application Events.
3. Paste in the following code in the Application class:

• C#:

private void Application_Startup(Object sender, StartupEventArgs e) {
    DarkMode.DarkMode.SetAppTheme(DarkMode.DarkMode.Theme.SYSTEM);
}

• Visual Basic:

Private Sub Application_Startup(sender As Object, e As StartupEventArgs) Handles MyBase.Startup

End Sub

Step 2: Enabling dark mode for each window

1. Open the class for one of your Forms.
2. Add the following code:

• C#:

protected override void WndProc(ref Message m) {
    DarkMode.WndProc(this, m, DarkMode.DarkMode.Theme.SYSTEM);
    base.WndProc(m);
}

• Visual Basic:

Protected Overrides Sub WndProc(ByRef m As Message)
    DarkMode.WndProc(Me, m, DarkMode.DarkMode.Theme.SYSTEM)
