This example uses WinQueryLboxItemText to copy all of the list box items into a buffer.

#define INCL_WINLISTBOXES
#define INCL_WINWINDOWMGR
#include <OS2.H>

LONG  cWindows;
char *szTemp;
HWND  hwndLB;
SHORT maxchar, index = 0;

cWindows = WinQueryLboxCount(hwndLB);

/* allocate a buffer for cWindows items. */

DosAllocMem((PPVOID)&szTemp,
            (ULONG)cWindows*256*sizeof(char),
             PAG_READ |
             PAG_WRITE |
             PAG_COMMIT);

/* loop through all of the items;  copying each */
/* one the buffer.                              */

while (index <= cWindows)
{
   maxchar = WinQueryLboxItemTextLength(hwndLB,index);
   WinQueryLboxItemText(hwndLB,
                        index++,
                        szTemp,
                        maxchar);
   (*szTemp)+=maxchar*sizeof(char); /* increment pointer by number */
                                    /* of bytes copied. */
