Declaration

[CLSCompliant(false)]
public static int TrackPopupMenu(IntPtr hMenu, uint uFlags, int x, int y, int nReserved, IntPtr hWnd, IntPtr prcRect)

Parameters

Type	Name	Description
System.IntPtr	hMenu	Handle to the shortcut menu to be displayed. The handle can be obtained by calling CreatePopupMenu to create a new shortcut menu, or by calling GetSubMenu to retrieve a handle to a submenu associated with an existing menu item.
System.UInt32	uFlags	Use zero of more of these flags to specify function options.More information can be found on the following link: http://msdn2.microsoft.com/en-us/library/ms648002.aspx
System.Int32	x	Specifies the horizontal location of the shortcut menu, in screen coordinates.
System.Int32	y	Specifies the vertical location of the shortcut menu, in screen coordinates.
System.Int32	nReserved	Reserved; must be zero.
System.IntPtr	hWnd	Handle to the window that owns the shortcut menu. This window receives all messages from the menu. The window does not receive a WM_COMMAND message from the menu until the function returns. If you specify TPM_NONOTIFY in the uFlags parameter, the function does not send messages to the window identified by hWnd. However, you must still pass a window handle in hWnd. It can be any window handle from your application.
System.IntPtr	prcRect	Ignored value.

Returns

Type

Description

System.Int32

If you specify TPM_RETURNCMD in the uFlags parameter, the return value is the menu-item identifier of the item that the user selected. If the user cancels the menu without making a selection, or if an error occurs, then the return value is zero. If you do not specify TPM_RETURNCMD in the uFlags parameter, the return value is nonzero if the function succeeds and zero if it fails. To get extended error information, call GetLastError.
