Hi Mariner,

This question is already answered:


       http://www.experts-exchange.com/topics/comp/lang/delphi/Q.10045961 (RONIT)
http://www.experts-exchange.com/Q.10066235 (ZIFNAB)

this is a snippet out of Q.10066235

----
     we could use OLE to transfer the data to Excel. (Or the older method DDE, but I prefer OLE, b'cose it's the newer method).

    Starting OLE communication is just one line, transferring data is as easy as a snip...

    Then we could iterate throught the result query and just transfer everything to Excel.

    Well, I can give you some more information about this :

    ExcelApp: Variant;

    To open Ole connection :

    ExcelApp:= CreateOleObject('Excel.Application');
    ExcelApp.Visible := True;

    To Close OLE connection :

    ExcelApp.Quit;

    To send data to active cell in Excel :

    try
      ExcelApp.ActiveCell := 1; {active cell is filled with number 1}
     except
      on E:EOleSysError do begin
       showmessage('OLESysError '+E.Message+IntToStr(E.ErrorCode));
      end
       else showmessage('unknown error, please report : ');
     end;

    BUT I advise you to also look at these fine components which already do your stuff and have some extra features. If you need more advise or want to
    make your own component, just say it and we'll help you.

    BUT look at them first! They are really learnfull!

    { export table, query, stringgrid to excel }

    { export query to word, excel }
    http://sunsite.icm.edu.pl/delphi/ftp/d20free/qexport.zip 
    which needs http://sunsite.icm.edu.pl/delphi/ftp/free/excel.zip

About the OLE-thing, this is a good article!

       go to OLE automation: Delphi, Word and Excel.

Hi Mariner,

What do you want to accomplish?

 I mostly use range as  ...Range['A1:B5']

 anyhow, you can do a lot, I mostly find them out, just by trying them out and looking at the libraries (see article)
