Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
idd = CInt(Request( "companyid "))
If Not IsPostBack Then
gstp()
End If
mycmd = New SqlCommand( "Select * from CompanyContent where companyid= " & idd, myconn)
myconn.Open()
dtr = mycmd.ExecuteReader()
While dtr.Read()
user_id = dtr( "user_id ").ToString
companyname = dtr( "companyname ").ToString
companyaddress = dtr( "companyaddress ").ToString
companyLxr = dtr( "companyLxr ").ToString
companytel = dtr( "companytel ").ToString

Sub gstp()
ids = (Convert.ToString(Request.QueryString( "user_id ")))
Dim dtr As SqlDataReader
Dim mycmd As SqlCommand
Dim myconn As SqlConnection = New SqlConnection(ConfigurationSettings.AppSettings( "connectionString "))
mycmd = New SqlCommand( "Select * from gstp where user_id= ' " & ids & " ' ", myconn)
myconn.Open()
dtr = mycmd.ExecuteReader()

下面的gstp里怎么读取上面的user_id的值 谢谢.
[解决办法]
把他保存到比如Session中,在第一次就Session[ "user_id "]＝１２３
下面就可读取了．
