求教一段插入块的代码

ccgt

各位大虾，下面是我写的一段代码，想实现的功能是在把路径为"D:\\test.dwg"的文件作为块插入到当前的图形中去。

但是不能成功运行。请指教

#include "StdAfx.h"
#include "StdArx.h"
#include "aced.h"
#include "migrtion.h"
#include "gemat3d.h "
#include "dbents.h "
//-----------------------------------------------------------------------------
// This is command 'CHARUDWG, by  [2008-1-30], ,
void test1basiccharudwg()
{
#ifdef OARXWIZDEBUG
 acutPrintf ("\nOARXWIZDEBUG - test1basiccharudwg() called.");
#endif // OARXWIZDEBUG
   // AcGeMatrix3d pt=(0,0,0);

 AcDbDatabase  extDb(Adesk::kFalse);  //定义一个空数据库

   extDb.readDwgFile("D:\\test.dwg");
    AcDbDatabase *ptempdb;
    extDb.wblock(ptempdb);
 AcDbObjectId  blockid;
 acdbCurDwg()->insert(blockid,"kkk",ptempdb);
 delete ptempdb;
 
 AcDbBlockTable *pBlkTbl;
 acdbHostApplicationServices()->workingDatabase()    
   ->getBlockTable(pBlkTbl, AcDb::kForWrite);

 AcGePoint3d ptInsert(100,100,0);
 AcDbBlockReference *pBlkRef = new AcDbBlockReference(ptInsert,blockid);
 AcDbBlockTableRecord *pBlkTblRcd;
 pBlkTbl->getAt(ACDB_MODEL_SPACE, pBlkTblRcd, AcDb::kForWrite);
 
 pBlkTblRcd->appendAcDbEntity(pBlkRef);
 pBlkTbl->close();
    pBlkRef->close();
 pBlkTblRcd->close();
  

}

出现什么样的错误啊

xtjtao

AcDbDatabase *ptempdb;

改为：

AcDbDatabase *ptempdb=new AcDbDatabase;

即可
