Question : using  CRichEditCtrl::FindText  ..

hi all!

I have build my own Find/Replace dialog ( derived from CDialog class) to search into a CRichEditCtrl .
now, everything is working just fine except 1 thing: how can implement "direction up" option ?? I mean to search from the current position to the beginning of the document ?? .. FindText method can't do it ..

Answer : using  CRichEditCtrl::FindText  ..

Here's an answer (AND IT's NOT PRETTY). :-(

The following code...
================================================
int n;
m_edit.SetWindowText("When your mom is mad with your dad, don't let her brush your hair.");
FINDTEXT range = {{0,0},"your"};
m_edit.SetSel(-1,-1);
m_edit.GetSel(range.chrg);
range.chrg.cpMax=0;
while((n = m_edit.SendMessage(EM_FINDTEXT, 0, (LPARAM)&range))!=-1){
  TRACE("text found at %d\n",n);
  range.chrg.cpMin = n;
  }
===================================================
Produces the following output...
text found at 56
text found at 26
text found at 5
===================================================
Indicating that indeed you can search backwards by swapping the cpMin & cpMax values around, BUT....

a) you can't use -1 to indicate the end of the file; and
b) you can't use version 1.0 of the rich edit control.
Because I created my Rich Edit control using the dialog resource editor I had to subsequently manually edit my .rc file as text and change
this line
CONTROL  "",IDC_RICHEDIT,"RichEdit" ,ES_MULTILINE | WS_BORDER | WS_TABSTOP,39,26,116,83

to this
CONTROL "",IDC_RICHEDIT1,"RichEdit20A" ,ES_MULTILINE | WS_BORDER |WS_TABSTOP,39,26,116,83

in order to be using version 2 of the rich text control.
(Hint use Spy++ to check the class of your rich text window).
