Windows 7 Progress Bar in Taskbar in C#

How do I code a progress bar for Windows 7 to also update itself on the taskbar?

There's a good article in MSDN magazine about the new taskbar APIs. And yes, the feature is awesome :-)

Essentially, it's all about implementing IFileOperation. There's a good article about using it in managed code here.

.NET Progress bar in taskbar on windows 7

You have to download the Windows API Code Pack for .NET and use those components to interact with Windows 7 (assuming you're not using .NET 4.0).

If you are using .NET 4.0, you should include the System.Windows.Shell namespace to gain access to the Windows 7 task bar features.

How do you show progress in the Taskbar with Winform C# 4.5

Here's a short example that you should be able to use to tailor to your needs:

    System.Windows.Window w = new System.Windows.Window();
    w.TaskbarItemInfo = new System.Windows.Shell.TaskbarItemInfo() { ProgressState = System.Windows.Shell.TaskbarItemProgressState.Normal };
    w.Loaded += delegate {
        Action<Object> callUpdateProgress = (o) => {
            w.TaskbarItemInfo.ProgressValue = (double) o;
        };

        Thread t = new Thread(() => {
            for (int i = 1; i <= 10; i++) {
                w.Dispatcher.BeginInvoke(callUpdateProgress, 1.0 * i / 10);
                Thread.Sleep(1000);
            }
        });
        t.Start();
    };

    System.Windows.Application app = new System.Windows.Application();
    app.Run(w);

To make the above work you need to have using System.Threading; at top and also add references of: PresentationCore, PresentationFramework, SystemXaml, WindowsBase.

Taskbar.ProgressBar.State = 
(TaskbarButtonProgressState)Enum.Parse(
        typeof(TaskbarButtonProgressState), 
        (string)comboBoxProgressBarStates.SelectedItem);

if (Taskbar.ProgressBar.State != TaskbarButtonProgressState.Indeterminate)
   Taskbar.ProgressBar.CurrentValue = progressBar1.Value;

Marquee progressbar in windows 7 taskbar

I've did it successfully (in .NET 2.0) with the help of these two references:

• Info on MSDN
• Posting on SO

The marquee is done with the "Indeterminate" mode. An excerpt from my code can be found here.
