CAA中怎么创建文字标注？(acoka和nctusdk两位帮忙看看吧)

各给高手：
       怎么在图上标注文本，如图，怎么用程序实现？请指点。

CATITPSFactoryAdvanced->CreateTextOnAnnotation()

谢谢高手

acoka兄，我把例子里面的代码改了，可是有错：
例子里面代码如下：
boolean CAATpiCreateTextCmd::CreateTextOnSelection (void * ipData)
{
  
  
  // Retrieve the selected geometry
  CATSO * pSelection = _pAgentGeometry ->GetListOfValues();
  
  if ( pSelection )
  {
    // Retrieve CATITPSFactoryAdvanced interfaces
    CATITPSFactoryAdvanced * piFactAdv = NULL;
    HRESULT rc = CATTPSInstantiateComponent (DfTPS_ItfTPSFactoryAdvanced,
                                     (void**) [$ piFactAdv)]
    if ( SUCCEEDED(rc) )
    {
      CATITPSText * piText = NULL;
      CATUnicodeString TextString("Sample 3D Text");
      CATMathPlane Plane = CATMathOIJ;
      rc = piFactAdv -> CreateTextOnGeometry (pSelection, &lane,
                                              [$TextString , &piText)]
……
由于我要在自己生成的点上作标注，所以就像你说的，new了一个CATSO*,代码如下：
boolean ChildCmd1::CreateTextOnGeometry(CATISpecObject_var spPointAsSpec)
{
  
  cout<<cout<<"CreateTextOnGeometry called !!!"<<endl;
  
  // Retrieve the selected geometry
  
    CATBaseUnknown* pPointAsBaseUnknown = spPointAsSpec;
  
  CATSO * pSelection = new CATSO(0);
  pSelection->AddElement(pPointAsBaseUnknown,0);
  if ( pSelection==NULL ) cout<<endl<<cout<<"pSelection==NULL"<<endl;
   if ( pSelection!=NULL )
  {
    // Retrieve CATITPSFactoryAdvanced interfaces
    CATITPSFactoryAdvanced * piFactAdv = NULL;
     HRESULT rc =CATTPSInstantiateComponent (DfTPS_ItfTPSFactoryAdvanced,
                                    (void**) [$ piFactAdv)]
   if ( SUCCEEDED(rc) )
    {
     cout<<endl<<cout<<"piFactAdv!=NULL"<<endl;
      CATITPSText * piText = NULL;
      CATUnicodeString TextString("Sample 3D Text");
      CATMathPlane Plane = CATMathOIJ;
      rc = piFactAdv -> CreateTextOnGeometry (pSelection, NULL,
                                            [$TextString , &piText)]
……
可是到这句CATIA就退出了：
  rc = piFactAdv -> CreateTextOnGeometry (pSelection, NULL,
                                            [$TextString , &piText)]
  
请问怎么解决呢？

求助

麻烦高手再看看了
：）

什么原因呢，高手来看看啊

不知道，如果你方便可以把workspace给公开，让大家提你debug一下
因为问题不一定就只在这段代码里

高手们再看看吧

不知道CATITPSFactoryElementary的
  CreateText(CATITTRS*,CATITPSText**) 函数可不可以达到我的要求?
