Looking for a replacement for COM (Serialization stuff)..

[lucky6969b]

I need to implement my own save functionality, as COM is proprietary, we don't have
a chance to have a taste of what the COM functions look,
I am considering to use XML instead of COM serialization, wonder how to
replace things like D3DXFileCreate(&file); , CreateSaveObject and AddDataObject all those
stuff. Any suggestions...

void IGameExporter::WriteXFile(IGameScene * ig, MCHAR const * name)
{
	
  animated_.clear();
  
  CComPtr<ID3DXFile> file;
  D3DXFileCreate(&file);
  static char const * xExtensions = XEXTENSIONS_TEMPLATES;
  static char const * xSkinExp = XSKINEXP_TEMPLATES;
  file->RegisterTemplates((void*)D3DRM_XTEMPLATES, D3DRM_XTEMPLATE_BYTES);
  file->RegisterTemplates((void*)xExtensions, strlen(xExtensions));
  file->RegisterTemplates((void*)xSkinExp, strlen(xSkinExp));
  file->RegisterTemplates((void*)kwTemplates, strlen(kwTemplates));
  CComPtr<ID3DXFileSaveObject> save;
  D3DXF_FILEFORMAT fileFormat = exportBinary_ ? D3DXF_FILEFORMAT_BINARY : D3DXF_FILEFORMAT_TEXT;
  if (exportCompressed_) {
    fileFormat |= D3DXF_FILEFORMAT_COMPRESSED;
  }
  //CHECK( file->CreateSaveObject(name, D3DXF_FILESAVE_TOFILE, fileFormat, &save) );
  file->CreateSaveObject(name, D3DXF_FILESAVE_TOWFILE, fileFormat, &save); //need to use D3DXF_FILESAVE_TOWFILE for Unicode! markblosser
  CComPtr<ID3DXFileSaveData> root;
  MCHAR const * slash = wcsrchr(name, '\\');
  if (!slash) slash = wcsrchr(name, '/');
  if (slash) ++slash; else slash = name;
  std::wstring n = convert_wname(slash);

 ExportFileData(save.p);
  //::OutputDebugString("kW X-port extracted scene data\n");

//  Sometimes you may wish to keep a single frame at the top. However, 
//  to preserve compatibility with previous exporters, put each top-level 
//  frame at the top of the file.
//  CHECK( save->AddDataObject(TID_D3DRMFrame, n.c_str(), 0, 0, 0, &root) );
  
  int nObjects = ig->GetTopLevelNodeCount();
  std::vector<IGameNode *> animated;
  for (int i = 0; i < nObjects; ++i) {
    IGameNode * n = ig->GetTopLevelNode(i);
    ExportNode(ig, n, save.p, gSelectedNodes.Count() == 0);
  }

  //  todo: write animations, if selected
  if (exportAnimation_) {
    ExportAnimations(save.p);
  }
  

  //::OutputDebugString("kW X-port saving X file\n");
  //save->Save();
  
  
}
