请问一个页面后台中 进行2次数据库读取 上下之间的值怎么传 在线等!!!!! 就像着样 Private Sub Page_Load(ByVal sender As Syste
m.Ob
ject,ByVal e As Syste
m.EventArgs) Handles MyBase.Load idd = CInt(
request( "
CompanyId ")) If Not IsPost
BACk 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 ").To
String companyname = dtr( "companyname ").To
String companyaddress = dtr( "companyaddress ").To
String companyLxr = dtr( "companyLxr ").To
String companytel = dtr( "companytel ").To
String MlbigClassName = dtr( "MlbigClassName ").To
String Compan
yms = dtr( "Compan
yms ").To
String Companyfw = dtr( "Companyfw ").To
String Companygm = dtr( "Companygm ").To
String Companykz = dtr( "Companykz ").To
String Companyyye = dtr( "Companyyye ").To
String Companydjg = dtr( "Companydjg ").To
String Companyyx = dtr( "Companyyx ").To
String Compan
ymj = dtr( "Compan
ymj ").To
String Companycz = dtr( "Companycz ").To
String Companydd = dtr( "Companydd ").To
String Companyyb = dtr( "Companyyb ").To
String zichan = dtr( "zichan ").To
String fuzai = dtr( "fuzai ").To
String Companysj = dtr( "Companysj ").To
String Companyyy = dtr( "Companyyy ").To
String Companyfr = dtr( "Companyfr ").To
String Companylx = dtr( "Companylx ").To
String companyweb = dtr( "companyweb ").To
String Companysw = dtr( "Companysw ").To
String Companykhyh = dtr( "Companykhyh ").To
String Companyyhzh = dtr( "Companyyhzh ").To
String Companyzy = dtr( "Companyzy ").To
String Companyzc = dtr( "Companyzc ").To
String cln = dtr( "cln ").To
String cly = dtr( "cly ").To
String clr = dtr( "clr ").To
String Companyrs = dtr( "Companyrs ").To
String Companygsjj = dtr( "Companygsjj ").To
String Companyjy = dtr( "Companyjy ").To
String End While dtr.Close() myconn.Close() End Sub Sub gstp() ids = (Convert.To
String(
request.Query
String( "
user_id "))) Dim dtr As SqlDataReader Dim mycmd As SqlCommand Dim myconn As SqlConnection = New SqlConnection(ConfigurationSet
Ting
s.AppSet
Tings( "connection
String ")) mycmd = New SqlCommand( "
SELEct * from gstp where
user_id= '' " & ids & " '' ",myconn) myconn
.open() dtr = mycmd.ExecuteReader() While dtr.Read() pic = dtr( "pic ").To
String End While dtr.Close() myconn.Close() End Sub End Class 下面的gstp里怎么读取上面的
user_id的值 谢谢. __________________________________________________________________________ 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． __________________________________________________________________________
