You can check active OLE object. Here is an example of it for Excel.<br />
<br />
try<br />
&nbsp; Excel:=GetActiveOLEObject(<wbr />'Excel.App<wbr />lication')<wbr />;<br />
except<br />
&nbsp; try<br />
&nbsp; &nbsp;Excel:=CreateOLEObject('Ex<wbr />cel.Applic<wbr />ation');<br />
&nbsp; except<br />
&nbsp; &nbsp;MessageDlg('Cannot create Ole object'#39<br />
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;+'Excel.Application!',mtEr<wbr />ror,[mbOK]<wbr />,0);<br />
&nbsp; &nbsp;exit;<br />
&nbsp; end;<br />
end;

Hi Community,<br />
<br />
I have developed an application in Delphi 5, which reads information from a MS WORD document and parses it into HTML. I have used OLE technology to achieve this. The problem is that if I start another instance of MS Word form the start menu while I am running my application and close the MS Word (application that i started from the start menu) the RPC server instance also gets destroyed and everytime I want to refresh the details in my Delphi application an error message appears saying &quot;RPC Server not found&quot; .<br />
<br />
How to overcome this problem ? I havetried using threads etc. Please suggest me something .<br />
<br />
Thanks and regards<br />
