It does not need to be since the length of the buffer is being passed to
DrawTextEx().  However, the length being passed is the size of the buffer,
not the length of the string that was stored in the buffer.  That will cause
DrawTextEx() to render more data than is actually in the buffer.  That needs
to be corrected, ie:

    char a[200] = {0};
    strncpy(a, cFileName.c_str(), 199);
    int length = min(cFileName.Length(), 199);

    DrawTextEx(lb->Canvas->Handle, a, length, &r, DT_MODIFYSTRING |
DT_PATH_ELLIPSIS, NULL)
