How do I use DDE with Delphi 2 ?

sample of dde for opening a new word document and inserting 2 lines in it, In this case Word is the server. Code for Using Delphi application as a server will be displayed soon.

uses ddeman;

procedure TForm1.Button1Click(Sender: TObject);
var
  DdeClientConv1: TDdeClientConv;
  DdeClientItem1: TDdeClientItem;
  Buf: PChar;
begin
  DdeClientConv1:=TDdeClientConv.Create(Form1);
  DdeClientItem1:=TDdeClientItem.Create(Form1);
  DDEClientItem1.DDEConv := DDEClientConv1;
  GetMem(Buf,100);
  Buf[0]:=#0;
  with DdeClientConv1 do
  begin
    ConnectMode := ddeManual;
    SetLink('WinWord','System');
    OpenLink;
    StrCat(Buf,'[FileNewDefault][Insert "Example for     dde"][InsertPara][Insert "from Delphi"]');
    ExecuteMacro(Buf,False);
    CloseLink;
  end;
  FreeMem(Buf,100);
  DDEClientItem1.Free;
  DdeClientConv1.Free;
end;

Thanks.

I'm waiting for an example of a Dephi application as a server.
How should I use the SetLink then ?
How do I pass text and not a macro?

BTW: Are you from Israel? Me too...

Yes I am.
To pass a text use pokedata. You will get the answer for the server tomorrow.

This is my client's source:
------------------------

procedure TForm1.Button1Click(Sender: TObject);
begin
     DDEClientItem1.DDEConv := DDEClientConv1;
     with DdeClientConv1 do
     begin
          ConnectMode := ddeManual;
          DdeService := 'ddesproj';
          ServiceApplication := 'ddesproj';
          DdeTopic := 'DDEServerConv1';
          if SetLink('ddesproj','DDEServerConv1') then
             MessageDlg('Link Established.', mtInformation, [mbOK],0);
          OpenLink;
     end;
end;

procedure TForm1.Button2Click(Sender: TObject);
begin
     Edit1.Text:=DdeClientItem1.Text;
end;

procedure TForm1.Button3Click(Sender: TObject);
begin
     DdeClientConv1.CloseLink;
end;

procedure TForm1.DdeClientItem1Change(Sender: TObject);
begin
  Edit1.Text:=DdeClientItem1.Text;
end;


This is my server's source:
--------------------------
procedure TForm1.Button1Click(Sender: TObject);
begin
     DdeServerItem1.ServerConv := DdeServerConv1;
     DdeServerItem1.Text := 'abcde';
end;

When I run the client and press button1 the link is established, and if the server is not
running, the client runs it.

Then I press button1 on the server, and expect the edit1.text in the client to change,
becuase of the DdeClientItem1Change procedure, but it doesn't.
If I try pressing button2 on the client edit1.text just turns empty...

Maybe my problem has to do with DdeclientItem1.DdeItem what should I set it to ?
The help is very unclear about it.

Thanks,

Thanks, I'll try it now.

I wanted to send text from the server to client, I'll try to chnage your code to do so.

I've got Delphi 2, there's no demo example for the DDE there, and the documentation and help about the DDE is very bad.

Hey, that makes us 3 Israelis on Delphi experts list...

pro...thanks for sharing this..

can i transfer a TObject or TRecord to there?
