Hi To All,

     I am trying to use MS Word from delphi. I can open, get text and close  the MS Word from Delphi Application. My only need is to get everything in MS Word that has been written. For example when i copy something to MS Word after opening the MS Word from Delphi  (Like pictures, formatted text etc.) and get the content of MS Word from delphi i lose the formats of the contents of the MS Word. The reason i need contents of the MS Word is to store this contents of the MS Word  in a database and then later i might load them into MS Word.
     How to owercome this issue?
    Thanks in advance.

Have you also though about using the TOleContainer control to allow your users to perform the editing of the word document?

It exposes savetofile/stream and loadfromfile/stream methods that allow you to persist and load the OLE stream (containing the word document), and makes loading/saveing the OLE data into a database much easier, as a blob field can be used to load/save  the OLE content stream.

Just a thought,
Russell

Yes, I can show you how the load / save streams work, but I am keeping the example to the basics so you will be understand how it works. I want to provide a simple working example that you can test / run, and don't want to complicate it with database stuff that would require extra code and not really have anything to do with the real problem.

But I will tell you this; integrating the code into a DB will require only minor work, as BLOB fields expose a LoadFromStream/SaveToStream, which would be the replacement for the FStreams array in my example.

Let me know if you question / problems,
Russell


Now back to the example...

-- source --
unit Unit1;

  Windows, Messages, SysUtils, Classes, Graphics, Controls, Forms, Dialogs,
  ComObj, ActiveX, OleCtnrs, StdCtrls, ExtCtrls;

  // Update the button states as well as the OLE doc stream
  Button1.Enabled:=(FIndex > 0);

  // Resource protection
  try
     // Check stream
     if (FStreams[FIndex].Size = 0) then
     begin
        // Create new object
        oxWord.CreateObject('Word.Document', True);
        // Set paper size to letter
        oxWord.OleObject.PageSetup.PaperSize:=2;
     end
     else
     begin
        FStreams[FIndex].Position:=0;
        oxWord.LoadFromStream(FStreams[FIndex]);
     end;
  finally
     // Do activation
     oxWord.DoVerb(ovPrimary);
  end;

end;

procedure TForm1.FormCreate(Sender: TObject);
var  dwIndex:       Integer;
begin

  // Set index
  FIndex:=0;

  // Create memory streams for example
  for dwIndex:=0 to High(FStreams) do FStreams[dwIndex]:=TMemoryStream.Create;

  // Update state of application

end;

procedure TForm1.FormDestroy(Sender: TObject);

     // Save to stream
     oxWord.SaveToStream(FStreams[FIndex]);
     // Increment index
     Inc(FIndex);
  finally
     // Update state
     UpdateState;
  end;

end;

begin

  // Clear current stream
  FStreams[FIndex].Clear;
  try
     // Save to stream
     oxWord.SaveToStream(FStreams[FIndex]);
     // Increment index
     Dec(FIndex);
  finally
     // Update state
     UpdateState;
  end;

end;

end.
