VC.net打开dot文件有问题，C#代码正常，烦死了
想打开一个dot文件，输入文字，C#代码正常，VC.net异常，困扰几天了，烦呀...
//--------------------------------------------C#
Word._Application oWord;
Word._Document oDoc;
oWord = new Word.ApplicationClass ();

object oMissing = System.Reflection.Missing.Value;
object Nothing = System.Reflection.Missing.Value;
object otemp ="e:\\hmh.dot"
oWord.Visible = false ;
oDoc = oWord.Documents.Add(ref otemp, ref oMissing,ref oMissing, ref oMissing);

object x = "name";
Word.Bookmark bm = oDoc.Bookmarks.Item(ref x);
bm.Range.Text = "Test_Name";//--正常，有Text属性！！！

object fn = "e:\\a1.doc";

oDoc.SaveAs(ref fn, ref Nothing, ref Nothing, ref Nothing, ref Nothing, ref Nothing, ref Nothing, ref Nothing, ref Nothing, ref Nothing, ref Nothing);
oWord.Documents.Close(ref Nothing, ref Nothing, ref Nothing);
oWord.Quit(ref Nothing, ref Nothing, ref Nothing);


//--------------------------------------------VC
Word:: _Application^ oWord;
Word::_Document^ oDoc;
oWord = gcnew Word::ApplicationClass ();

Object^ oMissing = System::Reflection::Missing::Value;
Object^ Nothing = System::Reflection::Missing::Value;
Object^ otemp ="e:\\hmh.dot" ;//GetDirectoryFromFile(System::Windows::Forms::Application::ExecutablePath)+@"Customers::dot";

oWord->Visible = true ;
oDoc = oWord->Documents->Add( otemp, oMissing, oMissing, oMissing);
System::Object^ x = "name";
Word::Bookmark^ bm = oDoc->Bookmarks->Item(x) ;
bm->Range->Text ----->没有Text属性？？？
我仔细比较了引用的Dll“Interop.Word.dll”，是一样的版本，这是为何？？？
恳求高手指点...

[解决办法]
try

bm->Range->SetText
[解决办法]
你
bm->Range.Text
