c# WinForms - Programmatically disable the method Application.EnableVisualStyles()?

Question

Is is possible to disable Application.EnableVisualStyles(); programmatically? I wanted to turn off the visual styles for a certain part of my application where I could have a colored progress bar. I know you can use System.Drawing to draw it on, but this is much more simpler if I could turn it off temporarily. Is this possible or am I going to have to draw it?

Answer 1

Credits go to GreatJobBob for linking me the MSDN page, the following achieved what I was looking for.

   using System.Windows.Forms.VisualStyles;

    Application.VisualStyleState = VisualStyleState.NonClientAreaEnabled;

This let me change the color of my progress bar without changing the rest of my controls and form.

Create your own progress bar class. Disabling Application.EnableVisualStyles will cause problems in other UIs such as the MessageBox. Here's a basic class to get you started, just change the forecolor to what you want it to be.

using System;
using System.Drawing;
using System.Windows.Forms;

class MyProgressBar : Control 
{
public MyProgressBar() 
{
    this.SetStyle(ControlStyles.ResizeRedraw, true);
    this.SetStyle(ControlStyles.Selectable, false);
    Maximum = 100;
    this.ForeColor = Color.Red; //This is where you choose your color
    this.BackColor = Color.White;
}
public decimal Minimum { get; set; }
public decimal Maximum { get; set; }

private decimal mValue;
public decimal Value 
{
    get { return mValue; }
    set { mValue = value; Invalidate(); }
}

protected override void OnPaint(PaintEventArgs e) 
{
    var rc = new RectangleF(0, 0, (float)(this.Width * (Value - Minimum) / Maximum), this.Height);
    using (var br = new SolidBrush(this.ForeColor)) 
    {
        e.Graphics.FillRectangle(br, rc);
    }
    base.OnPaint(e);
}
}
