Good day

I have a very funny error, that is driving me NUTS.

I use OLEContainer to open external files.
In my Delphi Code, I use :
                    OLEContainer1.AllowActiveDoc := false;
                    OLEContainer1.AllowInPlace := false;
                    OleContainer1.CreateObjectFromFile(OLEString,false);
                    OLEContainer1.DoVerb(0);

OLEString contains a path and filename, eg "c:\abc.ppt".

Now for the funny part, on some PC's, everything works 100%.
But, on other PC's it doesn't. I get the following two errors:
"Call Rejected By Callee"
"Server execution Failed"

The "Server execution Failed" mostly happens with MS-Powerpoint.
The "Call Rejected By Callee" mostly happens with MS-WORD.

I tested these on various versions of Windows:
WIN98SE
WIN2000
WINXPHome
WINXPProf

The versions of Office is 97, 2000 or XP.
I use Delphi 5.

Then, I also went into Explorer, and double-clicked the file that gives an
error via Delphi, and it opens it 100%.
ANY Help would be greatly appreciated.
Is there a place where I can check if all the Office DLL's and/or files are
present for OLE etc.

Lastly, when I open a MS-WORD document, and close the application, it closes
the document, but keep MS-Word open. How can I make it that when I close the
Application, that the document is still open.

Thanks
Michael

I have just tried it in Win2000 without a problem using Delphi 6. I put a
TOleContainer on a form without altering any properties and executed your
code as follows:

procedure TForm1.Button1Click(Sender: TObject);
begin
  if OpenDialog1.Execute then
  begin
    OLEContainer1.AllowActiveDoc := false;
    OLEContainer1.AllowInPlace := false;
    OleContainer1.CreateObjectFromFile(OpenDialog1.Filename,false);
    OLEContainer1.DoVerb(ovPrimary);
  end;
end;

There are two differences - I use a normal string as a filename and I use
the ovPrimary constant as a command (which is not 0).
