m_sModuleName = _T("C:/Program Files/Debenu/PDF Library/ActiveX/DebenuPDFLibraryAX0912.dll");

...

HMODULE hModule = ::LoadLibrary((LPCTSTR)m_sModuleName);

if( hModule != NULL ) {

IClassFactory* aClassFactory = NULL;

DllGetClassObjectFunc aDllGetClassObjectFunc = (DllGetClassObjectFunc)::GetProcAddress(hModule, "DllGetClassObject");

Hr = aDllGetClassObjectFunc(m_clsid, IID_IClassFactory, (LPVOID*)&aClassFactory);

if( SUCCEEDED(Hr) ) {

Hr = aClassFactory->CreateInstance(NULL, IID_IOleObject, (LPVOID*)&pOleControl);

}

aClassFactory->Release();

}

When it went to:

Hr = aClassFactory->CreateInstance(NULL, IID_IOleObject, (LPVOID*)&pOleControl);

The Hr was set the value "E_NOINTERFACE".

(I have installed the library and registered the dll.)

Hello,

Have you tried referring to the DebenuPDFLibraryAX0912.cpp and DebenuPDFLibraryAX0912.h files in the ActiveX\Import\CPlusPlus directory of your Debenu PDF Library installation ?

All of the required code should be included in these 2 files.

Andrew.
