Or you can use the  M  J shortcut also   All a matter of preference   the  CTRL-CHAR  codes are translated by the compiler   MyString     Hello      M    J    world      You can take the   away between the  M and  J  but then you will get a warning by the compiler  but it will still compile fine

In the System pas  which automatically gets used  the following is defined   const   sLineBreak     IFDEF LINUX  AnsiChar  10    ENDIF                    IFDEF MSWINDOWS  AnsiString  13 10    ENDIF     This is from Delphi 2009  notice the use of AnsiChar and AnsiString     Line wrap added by me    So if you want to make your TLabel wrap  make sure AutoSize is set to true  and then use the following code   label1 Caption     Line one  sLineBreak  Line two     Works in all versions of Delphi since sLineBreak was introduced  which I believe was Delphi 6

Sometimes I don t want to clutter up my code space  especially for a static label   To just have it defined with the form  enter the label text on the form  then right click anywhere on the same form   Choose  View as Text    You will now see all of the objects as designed  but as text only   Scroll down or search for your text   When you find it  edit the caption  so it looks something like    Caption    Line 1  13 Line 2  13 Line 3    13 means an ordinal 13  or ascii for carriage return   Chr 13  is the same idea  CHR   changes the number to an ordinal type     Note that there are no semi-colon s in this particular facet of Delphi  and     is used rather than       The text for each line is enclosed in single quotes    Once you are done  right-click once again and choose  View as Form    You can now do any formatting such as bold  right justify  etc   You just can t re-edit the text on the form or you will lose your line breaks   I also use  View as Text  for multiple changes where I just want to scroll through and do replacements  etc   Quick   Dave

I dont have a copy of Delphi to hand  but I m fairly certain if you set the wordwrap property to true and the autosize property to false it should wrap any text you put it at the size you make the label  If you want to line break in a certain place then it might work if you set the above settings and paste from a text editor   Hope this helps
