LB_SETCURSEL  3OCK079 

An application sends an LB_SETCURSEL message to select a string and scroll it into view, if necessary. When the new string is selected, the list box removes the highlight from the previously selected string.

LB_SETCURSEL

wParam = (WPARAM) index;    // item index

lParam = 0;                 // not used; must be zero

Parameters

index

Value of wParam. Specifies the zero-based index of the string that is selected. If the index parameter is -1, the list box is set to have no selection.

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.

Return Values

If an error occurs, the return value is LB_ERR. If the index parameter is -1, the return value is LB_ERR even though no error occurred.

Remarks

Use this message only with single-selection list boxes. You cannot use it to set or remove a selection in a multiple-selection list box.
