你是aspx的网页，不能用Msgbox,服务器不可能直接把Msgbox送到客户端的

比如Button.attribute.add("onclick","return",confirm("hi"))
或者Button.Attribute.Add("onclick", "alert('hi');")
或者Button.Attribute.Add("onclick", "alert('hi');")

在WebApplication下没有MsgBox()这个用法!要实现象这样的对话框,就要使用script来写!

你可以用这个代码试试：
Response.Write("<script>alert('hello')</Script>")
把hello换成你要输入的内容。
Response.Write("<script>alert('hello')</Script>")
把hello换成你要输入的内容。

以上是错误信息，为什么要把strFn "register.txt"转成integer?
这样写就是想弹出一个string的信息啊
MsgBox(Me, strfn)
[InvalidCastException: Cast from string "register.txt" to type 'Integer' is not valid.]
