Are you sure you want to revert this recent change?
Why count ExtendPoint for one line label text ?
The question is: Why not?
Speed?
If Str has only one line then
GetTextExtentPoint(DC, Lines[J], StrLen(Lines[J]), AP);
and
GetTextExtentPoint(DC, Str, Count, AP)
return the same AP
number 10000 may be greater
For example MessageDlg gets maximum size with the above 10000 instead of the
right width.
