L_VecDlgSetString

#include "lvdlg.h"

L_LVDLG_API L_INT L_VecDlgSetString(uString, pszString)

L_UINT32 uString;	index of a string
const L_TCHAR * pszString;	character string that contains the string to set

Sets the new string for the specified index

Parameter	Description
uString	Index into a list of strings. For a list of the strings, refer to Dialog Strings.
pszString	Character string that contains the new string to set.

Returns

SUCCESS	The function was successful.
< 1	An error occurred. Refer to Return Codes.

Comments

To retrieve the character string for a specified index, use L_VecDlgGetStringLen to determine the length of the string and to allocate a buffer of appropriate size. Then call L_VecDlgGetString to retrieve the string.
