Overview
The ListBoxSetCaret function moves the caret (focus rectangle) to a specified index position for a multiple select list box.
Syntax/Parameters
Syntax
int = ListBoxSetCaret ( int id, int index );
Parameters
id
An int containing the control ID of a list box.
index
An int specifying the zero-based index to place the caret.
Return Value
Returns an int as ERROR_NONE or a formatted error code on failure. Common error codes are as follows: ERROR_RANGE if id is an invalid control ID for the open dialog or ERROR_INVALID_HANDLE if no dialog is open. Use the GetLastError function to retrieve error information.
Remarks
This function sets 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.
If this function is used on a single-selection list box that does not contain a selected item, the caret index is set to the item specified by the index parameter. If the single-selection list box does contain a selected item, the function returns an error and the caret is not moved.
The control must have focus for the rectangle to be displayed.
