VC:CFindReplaceDialog(非模态对话框、IsWindow()、m_fr、GetFindString())

1、新建:

       if(pdlg!=NULL&&::IsWindow(pdlg->m_hWnd))

              pdlg->ShowWindow(SW_SHOW);

       else

       {

              pdlg=new CFindReplaceDialog();

              pdlg->m_fr.Flags=pdlg->m_fr.Flags|FR_MATCHCASE|FR_WHOLEWORD;

       }

       if(!::IsWindow(pdlg->m_hWnd))

       {

              pdlg->Create(FALSE,"字符串","改变字符串");

              pdlg->ShowWindow(SW_SHOW);

       }

2、消息映射:

       1)

       //{{AFX_MSG(CDialogDlg)

 

       afx_msg long OnFindReplace(WPARAM wParam,LPARAM lParam);

 

       //}}AFX_MSG

       DECLARE_MESSAGE_MAP()

       2)

       BEGIN_MESSAGE_MAP(CDialogDlg, CDialog)

       //{{AFX_MSG_MAP(CDialogDlg)

      

       ON_REGISTERED_MESSAGE(WM_FINDREPLACE,OnFindReplace)

      

       //}}AFX_MSG_MAP

       //    

       END_MESSAGE_MAP()

3、输出信息

              CString message="";

              if(pdlg->FindNext())

              {

              message+="查找下一个、\n\r";

              }

              message+="查找内容:";

              message+=pdlg->GetFindString();

              message+="\n\r";

              message+="替换内容:";

              message+=pdlg->GetReplaceString();

              message+="\n\r";

              AfxMessageBox(message);

              return 0;
