Introduction

Here is a code sample of OLE Automation of Microsoft Word. The project accepts two folders as a Source path and Destination path. It opens each Document file in the Source Path and Checks for bookmarks which start with 'P', if it finds one, it will create a new file using the bookmarked contents.

Steps:

Create a Dialog Project with MFC App Wizard, Tick the Automation support checkbox. Add 2 push buttons called 'Ellipsis1 and 'Ellipsis2'' and label them "source..." and 'destination...' (these are the browse buttons). Also add an 'Automate' button (this will launch the automation).
Open Class Wizard, Goto Automation tab,
Select Add Class
Select From a type Library
Select the file MSWORD*.OLD, where * can be anything depending on the Office installed on the machine.
From the List select the classes _Application, _Document, Documents, Bookmarks, Bookmark, Range and Selection.
Add two variables m_SourcePath & m_DestinationPath as CString to the Edit Boxes in the Dialog.
For the Ellipsis1 'click' event add the following code. This code is called when the browse button is clicked and opens a 'Browse' dialog for the source path.

void CWord1Dlg::OnEllipsis1() 
{
    BROWSEINFO browseInfo;
    browseInfo.hwndOwner = NULL ;
    browseInfo.pidlRoot = NULL; 
    browseInfo.lpszTitle = "Enter The Source Path";   
    browseInfo.ulFlags = 0 ; 
    browseInfo.lpfn = NULL; 
    browseInfo.lParam = 0;  

    LPITEMIDLIST lpItemIDList;
    if ((lpItemIDList = ::SHBrowseForFolder(&browseInfo))!= NULL)
    {
        SHGetPathFromIDList(lpItemIDList,m_SourcePath.GetBuffer(256));
        UpdateData(FALSE);
    }    
}

For the Ellipsis2 click event add the following Code

void CWord1Dlg::OnEllipsis2() 
{
    BROWSEINFO browseInfo;
    browseInfo.hwndOwner = NULL ;
    browseInfo.pidlRoot = NULL; 
    browseInfo.lpszTitle = "Enter The Destination Path";   
    browseInfo.ulFlags = 0 ; 
    browseInfo.lpfn = NULL; 
    browseInfo.lParam = 0;  

    LPITEMIDLIST lpItemIDList;
    if ((lpItemIDList = ::SHBrowseForFolder(&browseInfo))!= NULL)
    {
        SHGetPathFromIDList(lpItemIDList,m_DestinationPath.GetBuffer(256));
        UpdateData(FALSE);
    }        
}

Add the following code to the 'Automate' Button

void CWord1Dlg::OnAutomate() 
{
    COleVariant m_True((short)TRUE), m_False((short)FALSE), 
                m_Long((long)DISP_E_PARAMNOTFOUND, VT_ERROR);

    long startPos,endPos,m_LoopVar;

    BOOL m_FoundTheFile;
    
    CString m_FileName;

    UpdateData(TRUE);
    if(m_SourcePath=="" || m_DestinationPath =="")
    {
        MessageBox("Either Source Or Destination Path is Invalid",
                   "Easy Split Error",MB_ICONINFORMATION);
        return;
    }

    _Application appObj;

    if(!appObj.CreateDispatch("Word.Application"))
    {
        AfxMessageBox("Coud Not Create The Application Object");
    }

    appObj.SetVisible(FALSE);

    Documents docsObj(appObj.GetDocuments());

    _Document docObj,tempDocObj;

    CFileFind m_FileFind;

    m_FoundTheFile = m_FileFind.FindFile(m_SourcePath+"\\*.doc");

    while(m_FoundTheFile)
    {
        m_FoundTheFile=m_FileFind.FindNextFile();

        docObj.AttachDispatch(docsObj.Open(COleVariant(m_FileFind.GetFilePath()),
                              m_False,m_False,m_False,m_Long,m_Long,m_False,
                              m_Long,m_Long,m_Long  ));

        Bookmarks m_Books(docObj.GetBookmarks());    

        Bookmark m_Book;

        Selection selObj(appObj.GetSelection());

        startPos=0;
        endPos=0;

        for(m_LoopVar=1;m_LoopVar<= m_Books.GetCount();m_LoopVar++)
        {
            startPos=endPos ;
    
            docObj.Activate();
        
            m_Book.AttachDispatch(m_Books.Item(COleVariant(m_LoopVar)));

            if(m_Book.GetName().GetAt(0)!='P')

                continue;

            endPos= m_Book.GetEnd();

            selObj.AttachDispatch(appObj.GetSelection());

            selObj.SetRange(startPos,endPos);

            selObj.Copy();

            docsObj.Add(m_Long , m_Long );

            selObj.AttachDispatch(appObj.GetSelection());

            selObj.Paste();

            tempDocObj.AttachDispatch(appObj.GetActiveDocument());

            m_FileName.Format("%s%d.doc", m_DestinationPath+"\\"
                              + m_FileFind.GetFileTitle(), m_LoopVar);
        
            tempDocObj.SaveAs(COleVariant(m_FileName),m_Long,m_False,
                              COleVariant(""), m_True,COleVariant(""),
                              m_False,m_False,m_False,m_False,m_False);

            selObj.Shrink();

            m_Book.DetachDispatch();
        }
    }

    tempDocObj.Close(m_Long,m_Long,m_Long);

    docObj.Close(m_Long,m_Long,m_Long);

    docsObj.Close(m_Long,m_Long,m_Long);

    appObj.Quit(m_Long,m_Long,m_Long);

    m_FileFind.Close();

    MessageBox("Completed Successfully","Easy Split",MB_ICONINFORMATION);
}
