Shield_bm = new Bitmap(shield_wid, shield_hgt) Int min_x = WID, max_x = 0, min_y = HGT, max_y = 0 have text or the UAC shield won't appear.ītn.DrawToBitmap(bm, new Rectangle(0, 0, WID, HGT)) Return a bitmap containing the UAC shield. The GetUacShieldImage method shown in the following code gets an image of the system’s shield and returns it in a bitmap so you can add it to menu items, picture boxes, and other controls as appropriate. You could make an image of the shield and just add that where needed but the shield’s appearance changes depending on system settings (such as regular or large font size) and might change in future releases of the operating system. Unfortunately Microsoft has provided no way to add the shield to anything other than a button so adding it to other things is more work. SendMessage(btn.Handle, BCM_SETSHIELD, 0, 1) Give the button the flat style and make itītn.FlatStyle = .System

Public static void AddShieldToButton(Button btn) Make the button display the UAC shield. Public static extern int SendMessage(IntPtr hWnd, Note that the button must have FlatStyle prperty set to System and it must contain a text caption, even if the caption is a single space character. The AddShieldToButton method shown in the following code does it by sending the BCM_SETSHIELD message to the button. Unfortunately Microsoft hasn’t made this easy to do.Īdding the shield to a button is awkward but possible. In Windows Vista and later versions of Windows, you are supposed to add a UAC (user access control) shield to buttons that launch processes that require privilege elevation.
