integrating outlook in C++

Hello everybody,

I'm trying to make a dll that I'm going to call from Java.  The dll is supposed to  fetch the outlook contacts and export them to java.  

my cpp-program looks a bit like this:

#import<mso.dll> no_namespace rename("DocumentProperties", "DocumentPropertiesVM")
#import<VBE6EXT.olb> no_namespace
#import <msoutl.olb> rename("ExitWindows","ExitWindowsVM")
#include<tchar.h> //for strings
#include<jni.h> //java native interface
#include<myclass.h> //simply my class

even tried these imports in another version ...
#import "c:\Program Files\Common Files\Microsoft Shared\Office11\mso.dll" named_guids
#import "c:\Program Files\Microsoft Office\Office11\MSOUTL.OLB" \
      no_namespace exclude("_IRecipientControl", "_DRecipientControl")
...

JNIEXPORT void JNICALL Java_myclass_relaunch (JNIEnv *env, jobject obj)
 {
    //here the implementation of the code....
 }

now my problem is... I can't seem to make a connection with outlook..
if I use ... _ApplicationPtr pApplic ... as a declaration of outlook (something I've found on the net)
it won't work.  
Does anyone know how to make this connection work?  And maybe if I could use a namespace, other imports ... I thought I've read something about MAPI....

thx, Andy

ok,

JNIEXPORT jstring JNICALL Java_myclass_launch (JNIEnv *env, jobject obj, jstring txt)

{
    _ApplicationPtr pApp;
      _ItemsPtr pItems;
      MAPIFolderPtr pFolder;
      _ContactItemPtr pContact;
            
      HRESULT hr;

      printf("In contacts\n");

      try
      {
            
            hr=pApp.CreateInstance(__uuidof(Application));
            if (FAILED(hr))
            {
                  printf("Unable to instantiate Outlook.");
                  return env->NewStringUTF("0");
            }

            pFolder=pApp->GetNamespace(_bstr_t("MAPI"))->GetDefaultFolder(olFolderContacts);
            if (pFolder==NULL)
            {
                  printf("Could not find default contacts folder.");
                  return env->NewStringUTF("1");
            }
                              

            pItems=pFolder->GetItems();
            if (pItems==NULL)
            {
                  printf("Unable to get Contact Items.");
                  return env->NewStringUTF("2");
            }
            
            pContact=pItems->GetFirst();

            while(1)
            {
                  if (pContact==NULL)
                        break;
                  CString strTemp;
                  strTemp=(char *)pContact->GetFullName();
                  strTemp=strTemp + "<";
                  strTemp=strTemp + (char *)pContact->GetEmail1Address();
                  strTemp=strTemp + ">";
                  printf(strTemp);
                  return env->NewStringUTF(strTemp);
                  pContact=pItems->GetNext();
            }

      }
      catch(_com_error &e)
      {
            printf((char *)e.Description());
            return env->NewStringUTF(e.Description());
      }
  return env->NewStringUTF("Hier is wat misgegaan");
}

when I execute my java class, I get following output:
In outlook
Unable to instantiate Outlook

should that not be Outlook - what is Application?

well, I've tried all kinds of things there:
When using "Outlook" or "Outlook::Application", I get compilation errors... I've found a working example on the internet which uses Application, makes no sense to me, but it worked ... Guess Application references to Outlook in the imported dll mso.dll.  

When I try to work with msWord, I can use the namespace Word, but I can't find any for Outlook

This works with word

      LPDISPATCH pDisp;
      LPUNKNOWN pUnk;
      CLSID clsid;

      ::CLSIDFromProgID(L"Word.Application", &clsid); // from registry
      if(::GetActiveObject(clsid, NULL, &pUnk) == S_OK)
      {
            TRACE0("attaching\n");
            VERIFY(pUnk->QueryInterface(IID_IDispatch, (void**) &pDisp) == S_OK);
            app.AttachDispatch(pDisp);
            pUnk->Release();
      }
      else
      {

            TRACE0("creating\n");
            if(!app.CreateDispatch(clsid))
            {
                  TRACE0("Attatching after create\n");
                  if(::GetActiveObject(clsid, NULL, &pUnk) == S_OK)
                  {
                        TRACE0("attaching after create - with the prog\n");
                        VERIFY(pUnk->QueryInterface(IID_IDispatch, (void**) &pDisp) == S_OK);
                        app.AttachDispatch(pDisp);
                        pUnk->Release();
                  }
                  else
                  {
                        AfxMessageBox(IDS_5_ERR_UNK, MB_OK | MB_ICONSTOP);
                        return false;
                  }
            }
//            VERIFY(app.CreateDispatch(clsid) == TRUE);
      }


try replacing Word.Application with Outlook.Application
