word模板生成文件并显示在WebBrowser中，怎么实现再次生成word之前，先关闭之前的文件呢？避免提示文件被打开 需要生成副本……

当前代码如下：

Dim tm As String  = ProjectPath & "Attachments\\谈话通知书.doc" \'指定模板文件
Dim fl As String = ProjectPath & "Reports\\谈话通知书.doc" \'指定目标文件
Dim fl2 As String = ProjectPath & "Reports\\谈话通知书.pdf" \'指定目标文件  \'
Dim wrt As New WordReport(Tables("谈话通知书_table1"),tm,fl) \'定义一个WordReport
wrt.Build() \'逐行生成报表
wrt.Quit() \'退出
Dim wb As WinForm.WebBrowser = e.Form.Controls("WebBrowser1")
wb.Address=fl
Dim tb As WinForm.TabControl = e.Form.Controls("TabControl1")
tb.SelectedIndex=1
