  17. Im Powerbuilder: integer li_rc oleobject lole_smtp lole_smtp = CREATE oleobject li_rc = lole_smtp.ConnectToNewObject ( "DotNetSMTP.DotNetSMTP" ) if li_rc = 0 then lole_smtp.SenderName = "Christoph Menken" lole_smtp.SenderEmail = "christoph.menken@gmx.de" lole_smtp.RecipientEmail = "christoph.menken@gmx.de" lole_smtp.SmtpServer = "smtp.gmx.de" lole_smtp.MessageText = "This is a test, this is only a test." lole_smtp.Subject = "Dot Net via COM is cool" else MessageBox( parent.title, & "Error calling DotNetSMTP via COM: " + string(li_rc) ) end if .net Komponente via ComWrapper Tipps & Tricks 2

  18. Kundenauftrag der Be.as GmbH • Be.as ist eine Erweiterung des SAP Business One (SBO) • Vorteile: • Look&Feel wie SBO • Verwendung derselben Datenbank und der SBO DI-API • Leichte Erweiterungsmöglichkeit durch eigene PSR-basierte Skriptsprache • Problem: Extra Programm PB als Add-On Tipps & Tricks 2

  19. Lösung: SBO UI-API • COM+Objekt • Add-On in SBO • Integration in die SBO Eventsteuerug • Problem: Powerbuilder unterstüzt keine Implementation der Events, wie z.B. VisualBasics „with events“ PB als Add-On Tipps & Tricks 2

  20. SAP Business One • Lösung: PBNI Erstellen eines PBNI COM-Objekt, welches das SBO-UI-COM-Objekt verwendet und die Events in PB zur Verfügung stellt SBO UI API Registrierung Triggert Events PB PBNI-COM-Objekt PB als Add-On Tipps & Tricks 2

  21. Beispiel: PBNIOLEObject • Einfaches exemplarisches Beispiel • Integration eines PB-Programms in MS Word • von Bruce Armstrong PB als Add-On Tipps & Tricks 2

PBXEXPORT LPCTSTR PBXCALL PBX_GetDescription() { static const TCHAR desc[] = { "class n_cpp_oleobject from oleobject\n" "function integer CaptureEvents() \n" "function integer ReleaseEvents() \n" "event startup pbm_custom01 \n" "event quit pbm_custom02 \n" "event documentchange pbm_custom03 \n" "end class \n" }; return desc ; } PB als Add-On Tipps & Tricks 2

  23. PBXEXPORT PBXRESULT PBXCALL PBX_CreateNonVisualObject( IPB_Session* pbsession, pbobject pbobj, LPCSTR className, IPBX_NonVisualObject **obj ) { if ( strcmp( className, "n_cpp_oleobject" ) == 0 ) { *obj = new COLEObject() ; return PBX_OK ; } ; *obj = NULL ; return PBX_E_NO_SUCH_CLASS ; } PB als Add-On Tipps & Tricks 2

  24. BEGIN_DISPATCH_MAP(CEventSink, CCmdTarget) DISP_FUNCTION(CEventSink, "Startup", Startup, VT_EMPTY, VTS_NONE) DISP_FUNCTION(CEventSink, "Quit", Quit, VT_EMPTY, VTS_NONE) DISP_FUNCTION(CEventSink, "DocumentChange", DocumentChange, VT_EMPTY, VTS_NONE) END_DISPATCH_MAP() static const GUID IID_ICEventSink = {0x000209f7,0x000,0x0000,{0xc0,0x00,0x0,0x00,0x00,0x00,0x00,0x46 } }; BEGIN_INTERFACE_MAP(CEventSink, CCmdTarget) INTERFACE_PART(CEventSink, IID_ICEventSink, Dispatch) END_INTERFACE_MAP() PB als Add-On Tipps & Tricks 2

  25. void CEventSink::Startup() { //We'll never get this one, it happens before we capture the events #ifdef _DEBUG MessageBox( NULL, "Startup", "Message", MB_ICONEXCLAMATION | MB_OK ); #endif pbclass clz = m_userdata->session->GetClass(m_userdata->object); pbmethodID mid = m_userdata->session->GetMethodID(clz, "startup", PBRT_EVENT, "LUL" ); PBCallInfo ci; m_userdata->session->InitCallInfo(clz, mid, &ci); m_userdata->session->TriggerEvent(m_userdata->object, mid, &ci); m_userdata->session->FreeCallInfo(&ci); } PB als Add-On Tipps & Tricks 2

  26. void CEventSink::Quit() { #ifdef _DEBUG MessageBox( NULL, "Quit", "Message", MB_ICONEXCLAMATION | MB_OK ); #endif pbclass clz = m_userdata->session->GetClass(m_userdata->object); pbmethodID mid = m_userdata->session->GetMethodID(clz, "quit", PBRT_EVENT, "LUL" ); PBCallInfo ci; m_userdata->session->InitCallInfo(clz, mid, &ci); m_userdata->session->TriggerEvent(m_userdata->object, mid, &ci); m_userdata->session->FreeCallInfo(&ci); } PB als Add-On Tipps & Tricks 2

  27. void CEventSink::DocumentChange() { #ifdef _DEBUG MessageBox( NULL, "DocumentChange", "Message", MB_ICONEXCLAMATION | MB_OK ); #endif pbclass clz = m_userdata->session->GetClass(m_userdata->object); pbmethodID mid = m_userdata->session->GetMethodID(clz, "documentchange", PBRT_EVENT, "LUL" ); PBCallInfo ci; m_userdata->session->InitCallInfo(clz, mid, &ci); m_userdata->session->TriggerEvent(m_userdata->object, mid, &ci); m_userdata->session->FreeCallInfo(&ci); } PB als Add-On Tipps & Tricks 2

  28. Erzeugen der PBD erase pbnioleobject.pbx copy release\pbnioleobject.dll pbnioleobject.pbx "D:\Programme\Sybase\PowerBuilder 10.5\SDK\PBNI\pbx2pbd105.exe" pbnioleobject.pbd pbnioleobject.pbx pause PB als Add-On Tipps & Tricks 2

  29. Verbindung herstellen Integer li_rc SetPointer ( HourGlass! ) try inv_word = CREATE n_cpp_oleobject_word_application IF IsNull ( inv_word ) THEN Return li_rc = inv_word.ConnectToNewObject ( "Word.Application.8" ) IF li_rc <> 0 THEN Return li_rc inv_word.Visible = TRUE li_rc = inv_word.CaptureEvents() catch (Throwable MyError ) Return -1 end try CHOOSE CASE li_rc CASE 1 Return 1 CASE ELSE Return li_rc END CHOOSE PB als Add-On Tipps & Tricks 2

  30. PB als Add-On Tipps & Tricks 2

  31. PB als Add-On Tipps & Tricks 2

  32. PB als Add-On Tipps & Tricks 2

  33. Möglichkeiten der SBO- UI-API: • Reaktion auf SBO-Events • Erzeugen von SBO-Objekten, wie z.B. Form, Menü, Button, Datenfelder • Problem: • Keine Verwendung von PB-Objekte möglich • Somit auch keine Datawindows, bzw. PSRs PB als Add-On Tipps & Tricks 2

  34. Lösung: • Erzeugen einer SBO-Form • Erzeugen eines Childwindow in PB • Ermittlung der Handle beider Fenster • PB-Child als Child der SBO-Form setzen PB als Add-On Tipps & Tricks 2

  35. // Zunächst eine Form in SAP öffnen ls_uid = 'beas_' + string(now(),"hhmmssffff") ls_title = aw_window.title li_top = UnitsToPixels(aw_window.y, YUnitsToPixels! ) li_left = UnitsToPixels(aw_window.x, XUnitsToPixels! ) li_width = UnitsToPixels(aw_window.width, XUnitsToPixels! ) li_height = UnitsToPixels(aw_window.height, YUnitsToPixels! ) ll_rc = this.of_sboform_add( ls_uid, "", this.ft_sizable, this.fbs_sizable, "", lole_form, ls_title, li_left, li_width, li_top, li_height ) if not isvalid(lole_form) then return FAILURE // Dann das Handle das SBO Fensters holen (Klasse: TMMDIChildClass) SetNull( ls_WindowName ) setnull( ll_hStartingChild ) ll_hFrameWindow = FindWindowA( SBOFRAME_CLASS, ls_WindowName) // erst den Frame … ll_hClientWindow = FindWindowExA( ll_hFrameWindow, ll_hStartingChild, SBOCLIENT_CLASS, ls_WindowName) // dann den Client … ll_hChildWindow = FindWindowExA( ll_hClientWindow, ll_hStartingChild, SBOCHILD_CLASS, ls_WindowName) // und dann das Child … // Fenster positionieren aw_window.x = 0 // ganz nach links aw_window.y = 0 // ganz nach oben // Das Handle des Childs bilden ll_hPBWindow = handle(aw_window) if isnull(ll_hPBWindow) then return FAILURE // das Handle des SBO-Parents an das PB-Child übergeben ll_hParentWindow = ll_hChildWindow ll_rc = SetParent( ll_hPBWindow, ll_hParentWindow) PB als Add-On Tipps & Tricks 2
