Er nicht aber der Benutzer soll ja was zu tun haben, wenn er den richtigen auswählen muss.
Zitat von
Windows SDK:
An application sends an LB_SETCOUNT message to set the count of items in a list box created with the LBS_NODATA style and not created with the LBS_HASSTRINGS style.
wParam
Specifies the new count of items in the list box.
Microsoft Windows 95/Windows 98/Windows Millennium Edition (Windows Me) : 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 list box is limited only by available memory.
