How to write an Outlook AddIn
<![CDATA[
Title: How to write an Outlook AddIn
Create an ActiveX-Library
Save the project as e.g. "OLAddIn.dpr"
Create an automation object
Call the CoClass e.g. "AddIn"
Save the Unit as "AddIn.pas"
- procedure OnConnection(const Application: IDispatch; ConnectMode: ext_ConnectMode;
const AddInInst: IDispatch; var custom: PSafeArray); safecall;
- procedure OnDisconnection(RemoveMode: ext_DisconnectMode; var custom: PSafeArray); safecall;
- procedure OnAddInsUpdate(var custom: PSafeArray); safecall;
- procedure OnStartupComplete(var custom: PSafeArray); safecall;
- procedure OnBeginShutdown(var custom: PSafeArray); safecall;
Register the COM-object with "run / register ActiveX Server"
Register the AddIn, so that the Addin will be recognized by Outlook
- Create a new key: HKEY_CURRENT_USER\Software\Microsoft\Office\Outlook\Addins\OLAddIn.AddIn
- create a DWOrd "LoadBehavior" with the value 3
Compile the AddIn
Start Outllok
Sourcecode
library OLAddIn;
uses
ComServ,
OLAddIn_TLB in 'OLAddIn_TLB.pas',
AddIn in 'AddIn.pas' {AddIn: CoClass};
exports
DllGetClassObject,
DllCanUnloadNow,
DllRegisterServer,
DllUnregisterServer;
{$R *.TLB}
{$R *.RES}
begin
end.
unit AddIn;
{$WARN SYMBOL_PLATFORM OFF}
interface
uses
ComObj, ActiveX, OLAddIn_TLB, StdVcl, AddinDesignerObjects_TLB, Outlook_TLB;
type
TAddIn = class(TAutoObject, IAddIn, IDTExtensibility2)

procedure TAddIn.OnConnection(const Application: IDispatch;
ConnectMode: ext_ConnectMode; const AddInInst: IDispatch;
var custom: PSafeArray);
begin
// To show, that the AddIn has started just say anything
ShowMessage('Das AddIn wurde gestartet');

end;
procedure TAddIn.OnStartupComplete(var custom: PSafeArray);
