Windows 7 Control Pack for WinForms consists of the following controls and components, which provide functionality for creating a Windows 7-style application.
C1TaskbarButton works with Windows 7 taskbar extensions. You can adjust the application's Jump List, thumbnail toolbar, icon overlay, and a progress bar displayed on the taskbar button. Also, you can select a particular control on a form to use its contents as the thumbnail image.
C1TaskDialog is a powerful replacement for the standard message box under Windows Vista or newer operating systems. Similar to other standard dialog boxes (such as OpenFileDialog) you can set simply a few properties, then call to the Show method to display the dialog box at run-time.
