动态创建webbrowser所引起的问题，高手看看！
代码如下：
CppWebBrowser2=new TCppWebBrowser(Form1);
Variant s;
s="http://www.china.com";
(dynamic_cast<TControl*>(CppWebBrowser2))->Parent=Form1;
CppWebBrowser2->Navigate(s);
CppWebBrowser2->OnDocumentComplete=CppWebBrowser2DocumentComplete;
最后一句总是出现以下错误.
[C++ Error] MainForm.cpp(684): E2034 Cannot convert 'void (_fastcall * (_closure )(TObject *,IDispatch *,Variant *))(TObject *,IDispatch *,Variant *)' to 'void (_fastcall * (_closure )(TObject *,IDispatch *,tagVARIANT *))(TObject *,IDispatch *,tagVARIANT *)'
其它的某一些事件也是一样.
高手帮忙解决一下吧！

第三个参数类型修改一下
如
void __fastcall TForm1::CppWebBrowser2DocumentComplete(TObject *Sender,LPDISPATCH pDisp, tagVARIANT *URL)
{
ShowMessage("OK!");
}Top
