The following is an example of a manifest to allow your application to support the visual styles available in Windows XP if you are using version 1.0 of the .NET Framework. The manifest can be added to your application as a resource or as a stand-alone text file. The manifest file resides in the same directory as the executable file, and the name of the text file must be the complete name of the executable file with an additional file name extension of.manifest. For example, the manifest file for MyApp.exe would be MyApp.exe.manifest. This example assumes that the
FlatStyle properties of the controls in your application are set to System.

In the case of the Popup style button, this enumeration controls some behavior as well as appearance. The Popup style control initially appears Flat until the mouse pointer moves over it. When the mouse pointer moves over the Popup control, it appears as a Standard style control until the mouse pointer is moved off of it again.
If the System style is used, the appearance of the control is determined by the user's operating system and the following property values will be ignored: Control.BackgroundImage,
TextAlign. In addition, the Control.BackColor property will be ignored for button controls. If supported, users can change the appearance of controls by adjusting the appearance settings of their operating system.
When the FlatStyle property of the RadioButton and CheckBox classes is set to
System, the control is drawn by the user's operating system and the check alignment is based upon the
CheckAlign and ButtonBase.TextAlign property values. The
CheckAlign property value is not changed, but the appearance of the control can be affected. The check box is horizontally aligned with either the left or right edge of the control (a left or center alignment appears left aligned, right remains unchanged), and vertically aligned the same as the descriptive text. For example, if you have a CheckBox control with a
CheckAlign property value of ContentAlignment.MiddleCenter and a TextAlign property value of ContentAlignment.TopRight, and the FlatStyle property value is set to
System, the check box alignment will appear to be ContentAlignment.TopLeft while the text alignment remains unchanged.
FlatStyle property to System is not advisable if you need to display an image on a control, display an image as a control's background, or perform precise text alignment.
