We have the learn open a file by using an Open button, this is code below:

1 voidCfilecrcdlg::onopen ()2 {3     //Todo:add your control notification handler code here4 WORD N;5 WORD i;6BYTE szchar[201];7BYTE crc_hex[4],BT;8CString strtemp="";9 CFileDialog Filedlg (TRUE);TenFiledlg.m_ofn.lpstrfilter="All files (*. *)"; One     if(Filedlg.domodal () = =IDOK) A     { - CFile file (filedlg.m_ofn.lpstrfile,cfile::moderead); - UpdateData (TRUE); theM_path + =file. GetFilePath (); -M_path + ="\ r \ n"; -         //clear the Edit Dlg -I=0xFFFF; +memset (Szchar,0,201); -          while(file. Read (Szchar, $)) +         { An=0; at              while(Szchar[n]) -             { -I=crc_16 (I,szchar[n]); -n++; -             } -memset (Szchar,0,201); in         } -strtemp. Format ("%d", i); tom_crc_dec+=strtemp; +m_crc_dec+="\ r \ n"; -          the Swap_word_byte (i,crc_hex); *          for(i=0;i<4; i++) $         {Panax NotoginsengBT =* (Char*) (crc_hex+i); -strtemp. Format ("%c", BT); them_crc_hex+=strtemp; +         } AM_crc_hex + ="\ r \ n"; the file. Close (); + UpdateData (FALSE); -     } $}

void Cfilecrcdlg::onopen ()

Now, we is going to using another-to-open a file and get the CRC check sum.

Here is the code:

1 voidcfilecrcdlg::ondropfiles (hdrop hdropinfo)2 {3     //todo:add your message handler code here and/or call default4 UINT J,ifilecount;5     CharFile_name[max_path];6     //Variable for CRC7 WORD N;8 WORD i;9BYTE szchar[201];TenBYTE crc_hex[4],BT; OneCString strtemp=""; A  -Ifilecount=::D ragqueryfile (Hdropinfo,0xFFFFFFFFNull0); -      the      for(j=0; j<ifilecount;j++) -     { - ::D ragqueryfile (Hdropinfo,j,file_name,max_path); - CFile file (file_name,cfile::moderead); + UpdateData (TRUE); -M_path + =file. GetFilePath (); +M_path + ="\ r \ n"; A         //clear the Edit Dlg atI=0xFFFF; -memset (Szchar,0,201); -          while(file. Read (Szchar, $)) -         { -n=0; -              while(Szchar[n]) in             { -I=crc_16 (I,szchar[n]); ton++; +             } -memset (Szchar,0,201); the         } *strtemp. Format ("%d", i); $m_crc_dec+=strtemp;Panax Notoginsengm_crc_dec+="\ r \ n"; -          the Swap_word_byte (i,crc_hex); +          for(i=0;i<4; i++) A         { theBT =* (Char*) (crc_hex+i); +strtemp. Format ("%c", BT); -m_crc_hex+=strtemp; $         } $M_crc_hex + ="\ r \ n"; - file. Close (); - UpdateData (FALSE); the     } - ::D ragfinish (hdropinfo);Wuyi cdialog::ondropfiles (hdropinfo); the}

void Cfilecrcdlg::ondropfiles (Hdrop hdropinfo)

OK, Enjoy. Thank you!
