CB_GETCOUNT  41I9_G7 

An application sends a CB_GETCOUNT message to retrieve the number of items in the list box of a combo box.

CB_GETCOUNT

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

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

Parameters

This message has no parameters.

Return Values

The return value is the number of items in the list box. If an error occurs, it is CB_ERR.

Remarks
