As I understand it, you can change the color of a text fragment in RichEdit5 like this:

Code: Select all  Expand view

method Colorize(nStart, nEnd, nColor)

However, I didn't understand how to find this fragment in RichEdit5

Dear Yuri,

METHOD Find( cFind, lDown, lCase, lWord ) CLASS TRichEdit5

Thanks !

hi,

as i can say Fivewin have HB_FUNC( FINDTEXT ) but not HB_FUNC( REPLACETEXT )
but all Structure are in c:\fwh\source\winapi\findtext.c

under HMG i have this

Code: Select all  Expand view

static TCHAR       cFindWhat[ 1024 ];
static TCHAR       cReplaceWith[ 1024 ];

Jimmy, what does RichEdit5 have to do with it ?
I tried both :Find() and :Search() - unsuccessfully

hi,

Jimmy, what does RichEdit5 have to do with it ?

HMG CODE work with RTF or TXT using

Code: Select all  Expand view

    if( lReplace )
         hDlgFindReplace = ReplaceText( &FindReplace );
      else
         hDlgFindReplace = FindText( &FindReplace );

i´m not sure about Fivewin HB_FUNC( FINDTEXT ) if it work with UNICODE ... have not test it yet
but i know that HMG Version does work with German "Umlaute"
