请问一下，在提交表单的时候，那表单内容不支持中文。英文就可以，这到底是怎么一个回事。

先谢过了。

<%@ Import Namespace ="System.Data" %>
<%@ Import Namespace ="System.Data.SqlClient" %>
<%@ Page Language="VB" Debug="true" %>

'接收表单送过来的数据
'------------------------------------------------------------------
Dim useName As String = Request.Form("useName").ToString() '姓名

Dim useMetier As String = Request.Form("useMetier").ToString() '职业

Dim useMailId As String = Request.Form("useMailId").ToString() 'Mail地址

Dim useAddress As String = Request.Form("useAddress").ToString() '祥细地址

Dim useAdvise As String = Request.Form("useAdvise").ToString() '建议



'连接数据库
'------------------------------------------------------------------


Dim strConn As String = "Integrated Security=true;database=test;"
Dim strComm As String = "select 姓名,职业, Email地址,详细地址,有何建议from ta"

Dim myConnection As New SqlConnection(strConn) '连接

Dim myDataset As New DataSet() '数据集

Dim myDataAdapter As SqlDataAdapter
myDataAdapter = New SqlDataAdapter(strComm, myConnection) '适配器

myDataAdapter.Fill(myDataset, "ta") '填充Dataset

Dim myRows As DataRow = myDataset.Tables("ta").NewRow()
myRows("姓名") = useName
myRows("职业") = useMetier
myRows("Email地址") = useMailId
myRows("详细地址") = useAddress
myRows("有何建议") = useAdvise

myDataset.Tables("ta").Rows.Add(myRows)
Dim myCommandbuilder As New SqlCommandBuilder(myDataAdapter)
myDataAdapter.InsertCommand = myCommandbuilder.GetInsertCommand()

myDataAdapter.Update(myDataset, "ta") '更新数据

%>

补充：
我的代码是这样的。是不是少了对字符的编码，如果是我应该怎么加？
