LB_SETCARETINDEX
An application sends an LB_SETCARETINDEX message to set the focus rectangle to
the item at the specified index in a multiple-selection list box. If the item
is not visible, it is scrolled into view.
LB_SETCARETINDEX
wParam = (WPARAM) index; // item index
lParam = MAKELPARAM(fScroll, 0); // flag for scrolling item
Parameters
index
Value of wParam. Specifies the zero-based index of the list box item that is to receive the
focus rectangle.
Windows 95: The wParam parameter is limited to 16-bit values. This means list boxes cannot contain
more than 32,767 items. Although the number of items is restricted, the total
size in bytes of the items in a listbox is limited only by available memory.
fScroll
Value of lParam. If this value is FALSE, the item is scrolled until it is fully visible; if
it is TRUE, the item is scrolled until it is at least partially visible.
Return Values
If an error occurs, the return value is LB_ERR.

Nostalgia .Net |

.Net is powerful, but not all-powerful, so sometimes we need to use Win32 API for our .Net applications. It's simple enough with Platform Invoke if you have Win32 skill, but we do not always have time to dig the ancient documentation, declare the special types that are compatible with Win32, find the values of the Win32's constants and so on. Nostalgia .Net offers several simple-to-use classes, and components that will allow you to forget about the headache of Win32 and just use the power of Win32 in your application the same way as you use the native. Net classes. More » |
