some old code of mine. First form with some buttons, then Excell unit that starts excell and fill some fields.

some procedures are in dutch: localiseerEnVerander = localise and change.

Good luck!
Floris.

Sorry a few typos:

(uses OleAuto;)

var
  v: variant;

procedure CreateExcel;
begin
  v:=CreateOleObject('Excel.Application');
  v.Application.Workbooks.Open('c:\My Documents\excel.xls');
  v.Visible := True;//only needed if you want to see the sheet
end;

procedure writetocell(Arow,Acol: integer; AValue: variant);                             begin
  v.ActiveWorkBook.ActiveSheet.cells(Arow, Acol).Value:= AValue;
end;

procedure QuitExcel;
begin
 v.Quit; //will destroy the Excel object!

Aubs,

1.It seem that it works, but there is a problem in puting data in cells, how can I do that without using Variant, I need  a small example of sending Numberic data.

2. How I open new document

3. Where can I find another command? (Optional)

Thanks Epsylon and Abus, I'll give both of the the points

But befor that, what about different versions of Excel (2000, 95 and 97)? Did it work with all versions?

Hi Azzoz, about the different versions, as always with software development, nothing is sure until tested and approved. But the most common features are (should be) upward compatible.

I don't know if Excel 95 supports automation at all...
