You can do this. you just need to add a reference to the dll in the Proect\Property window under the COmmon Property\Refernece link. Click to the add new reference button and browse to the you .net dll. You can now use your dll in MFC. You should use gcnew insteasd of new for creating an object to a managed class.

Hi Dear, I am trying to index metadata for doc file for indexing purpose using IFilter implementation. I have the OffFilter.dll which implements IFilter for office documents like .doc etc. I am able to load the filter but the problem is it is only retrieving the contents of the file. I want other data like size of the file etc which it is not returning. Below is the code snippet =============================== CComQIPtr pFilterText; //Initialize the COM LIB if ( FAILED( ::CoInitialize( NULL ) ) ) return ; HRESULT hr; CLSID clsId; IFilter * pFilter; WCHAR * cPath = _T("D:\\Projects\\NBS\\Development items for Oasys post release 1.0.0.46 (RasterX issues).doc"); hr = ::LoadIFilter(cPath, NULL, (void**)&pFilter ); //LoadIFilter uses a means such as CoCreateInstance() to create the filter and then calls IPersistFile::Load with the name of the specified file. if ( FAILED( hr ) ) { return ; } CComQIPtr pPersistFile( pFilter ); SCODE ret = 0; FULLPROPSPEC *fullPropSpec1, *fullPropSpec2; fullPropSpec1 = new FULLPROPSPEC; fullPropSpec2 = new FULLPROPSPEC; GUID guidPropSet = PSGUID_STORAGE; fullPropSpec1->guidPropSet = guidPropSet; fullPropSpec1->psProperty.ulKind = PRSPEC_PROPID; fullPropSpec1->psProperty.propid = PID_STG_CONTENTS ; fullPropSpec2->guidPropSet = guidPropSet; fullPropSpec2->psProperty.ulKind = PRSPEC_PROPID; fullPropSpec2->psProperty.propid = PID_STG_SIZE; FULLPROPSPEC* pArrFPS [] = {fullPropSpec1, fullPropSpec2}; ULONG flags = 0; ULONG grFlags = IFILTER_INIT_CANON_PARAGRAPHS | IFILTER_INIT_APPLY_INDEX_ATTRIBUTES | IFILTER_INIT_HARD_LINE_BREAKS | IFILTER_INIT_CANON_HYPHENS | IFILTER_INIT_CANON_SPACES; sizeof(FULLPROPSPEC); ret = pFilter->Init(grFlags ,2 , *pArrFPS, &flags ); ATLASSERT( SUCCEEDED( ret ) ); STAT_CHUNK statChunk; WCHAR szText[1024] =_T(""); ULONG lLength = 1024; ret = 0; CString str; bool bDone = false; while(1) { size_t s = sizeof(grFlags); ret = pFilter->GetChunk( &statChunk ); if(statChunk.attribute.psProperty.propid == 12) AfxMessageBox("Size retrived"); if(statChunk.attribute.psProperty.propid == 19) AfxMessageBox("Content retrived"); } I doubt I am passing wrong attributes to thr IFilter::Init() function. Can anybody please help me? Let me know if you need more info and a sample project also.

Hi, I want to enable drag and drop for tree view. I used DragAcceptFile(TRUE) in the tree view and that worked fine for explorer folder. My other requirement is the drag and drop should also work for email attachments say for outlook or gmail account. To clarify I want to drag an attachement from an email to a node in the treeview. Unfortunately when I am trying to do this it is not enabling and no message is being fired. can anybody help me please?

One way is convert std::string to CString using marshalling
