Porting CS3 to CS4 : Links problem

Question

I've read the "porting-guide.pdf" and I'm a bit confused in their "recipe" to convert the code from CS3 to CS4, dealing with the links. Below...is my current PC CS3 code, which basically takes the input of a filename and then proceeds to check ALL the LINKs on the page to see if the item is actually ON the page.  Can someone review this...and convert this function so that it will work in CS4.<br /><br />-Thanks...Mark<br /><br />int IsItemOnPage(char *full_filename)<br />{<br />  int links=0;<br />  int i;<br />  int linkcount;<br />  char *cptr;<br />  char parent_da[512];<br />  int max;<br />  int on_page=0;<br />  char file_on_page[512];<br /><br />  IDocument* document = Utils<ILayoutUIUtils>()->GetFrontDocument();<br />  // 07/02/07 (CMC) moved this code within if(document != nil) block<br />  /*IDataBase* database = ::GetDataBase(document);<br />  ASSERT(database);<br />  if(!database)<br />   {<br />      //1-13-06<br />      //return kFailure;<br />     return(on_page);<br />   }*/<br /><br />  //11-18-05<br />  if(document != nil)<br />  {<br />     // 07/02/07 (CMC) moved this code within if(document != nil) block<br />     IDataBase* database = ::GetDataBase(document);<br />     ASSERT(database);<br />     if(!database)<br />     {<br />          //1-13-06<br />          //return kFailure;<br />          return(on_page);<br />     }<br />     PMString doc_name;<br />     document->GetName(doc_name);<br />     if(doc_name.IsEmpty()==FALSE)<br />     {<br />     max=sizeof(parent_da);<br />     cptr=&parent_da[0];<br />     doc_name.GetCString(cptr,max);<br />     }<br />  }<br />  else<br />  {<br />    return(0);//do nothing.<br />  }<br />  <br />  InterfacePtr<ILinksManager> linksmanager(document, IID_ILINKSMANAGER);<br />  linkcount = linksmanager->GetLinkCount();<br /><br />  for (i = 0; i < linkcount; i++)<br />  {<br />    UIDRef uidr(linksmanager->GetNthLinkUID(i));<br />    InterfacePtr<IDataLink> iDataLink(uidr,IID_IDATALINK);<br />    if ( iDataLink != NULL )<br />    {<br />      PMString formatName;<br />       //PMString *ppm;<br />      uint32 formatType;<br />      NameInfo ni;<br />      iDataLink->GetNameInfo(&ni,&formatName,&formatType);<br />      PMString* namePtr = ni.GetFilename();<br />      <br />      //3-13-06<br />      PMString* fullStringPtr = iDataLink->GetFullName();<br />      <br />      if( namePtr )<br />      {<br />        //TRACE("linked file name: %s (dirID=%d)\n",namePtr->GrabCString());<br />        if(DEBUG_MODE>0)<br />         {<br />           sprintf(LOG_FILE_MESG,"IsItemOnPage::File(%d)=%s",links,fullStringPtr->GrabCString());<br />           LogToLogFile(LOG_FILE_MESG);<br />         }  <br />        links++;           <br />        cptr=&file_on_page[0];<br />        fullStringPtr->GetCString(cptr,sizeof(file_on_page));<br />          //10-11-07<br />        //if(stricmp(file_on_page,full_filename)==0)<br />          if(Compare_FilePaths(file_on_page,full_filename))<br />          on_page=1;<br /><br />      }<br />    }<br />  }//EOF...for loop..<br /> return(on_page);<br /><br />}
