[求助]关于打开文件的问题[/我是新手]

偶是新手，各位大虾帮帮忙吧。。。。多谢了~~

在autocad2006下面，想实现打开一个dwg文件的功能。代码如下：

void openDocHelper(void *dwgpath)
{
AcApDocument* pDoc = acDocManager->curDocument();
CString* tmp = (CString*)dwgpath;
if(acDocManager->isApplicationContext()){
  Acad::ErrorStatus result = acDocManager->appContextOpenDocument((const char *)dwgpath);
  if(result != Acad::eOk)
   acutPrintf("\nERROR: %s\n", acadErrorStatusText(result));
}else
  acutPrintf("\nERROR: in Document context :%s\n",acDocManager->curDocument()->fileName());
}

void OpenDwg(CString dwgpath){
if(acDocManager->isApplicationContext()){
  Acad::ErrorStatus result = acDocManager->appContextOpenDocument(dwgpath);
  if(result != Acad::eOk){
   acutPrintf("\nERROR: %s\n", acadErrorStatusText(result));
  }  
}else{
  acDocManager->executeInApplicationContext(openDocHelper, &dwgpath);
}
}

========================================

当我调用OpenDwg（some file）;时，总是返回eFilerError ，这是怎么回事啊？？

静待各位大虾解答，多谢了。。。
