RE is a CRichEditCtrl object. What I have is a spell checker. There are four choices for the user 1st Ignore,Ignore All, Change, and Change All.
so basically I have this options in a switch statement.
Since I already have the Change working how do I implement the ChangeAll. These are push buttons.If the spell checker detects a mispelled word. It list the suggestion in the list box.
switch (idAction)
                                          {
                                          case IDIGNORE:
                                                // skip this instance of pToken
                                                break;
                                          case IDIGNOREALL:
                                                // skip every instance of pToken - add to ignore list
                                                break;
                                          case IDCHANGE:
                                                // change this instance of pToken to dlg.m_strChange
                                                RE.ReplaceSel(LPCTSTR(dlg.m_strChange), true);
                                                nNew = dlg.m_strChange.GetLength();
                                                int dxChars += (nNew - nOld);
                                                
                                                break;
                                          case IDCHANGEALL:
                                                // change every instance of pToken to dlg.m_strChange
                                                break;
                                          default:
                                                break;

Use the FindText member of CRichEditCtrl and use a while loop to find every instance of the word by using the WHOLEWORD attribute for FindText.

Using the found position of the word execute a SetSel call to set the selection to the found word. Then use the same ReplaceSel call for your IDCHANGE code.
