L_LVDLG_API L_INT L_VecDlgSetString(uString, pszString)
Index into a list of strings. For a list of the strings, refer to Dialog Strings.
Character string that contains the new string to set.
| Value | Meaning |
|---|---|
| SUCCESS | The function was successful. |
| < 1 | An error occurred. Refer to Return Codes. |
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.
