Re: Web Page reading from AS400

Justin,

Many and several.  Here's a code snippet:

' Global.ASA file contains the following information:
'   - Userid
'   - Password
'   - AS/400 System Name
'   - ODBC data source name
<!--

 Global.asa
 Session level variables
 -->
<SCRIPT LANGUAGE="VBScript" RUNAT="Server">

Sub Session_OnStart
    Session("AS400_Userid") = "UID"
    Session("AS400_Password") = "PASS"
    Session("AS400_SystemName") = "CAXPRESSCONNECTIONNAME"
End Sub

</SCRIPT>

Active server page code snippet:

'Always DIM your variables, even though you don't have to.
'All ASP variables are variants, you cannot specify the data
'type

Dim AS400Connection
Dim AS400Command
Dim AS400Recordset
Dim ConnectionString
Dim CommandText
Dim CommandType

On Error Resume Next

'Setup appropriate connection string and command information
ConnectionString = "Provider=IBMDA400;Data Source=" &
Session("AS400_SystemName") & ";"
CommandType = adCmdText

CommandText = "SELECT FIELDS FROM LIBRARY.FILE " _
            & "WHERE CONDITIONS " _
            & "ORDER BY STUFF"
'Open the connection
Set AS400Connection = Server.CreateObject("ADODB.Connection")
AS400Connection.Open
ConnectionString,Session("As400_Userid"),Session("AS400_Passwo
rd")

Set AS400Command = Server.CreateObject("ADODB.Command")
AS400Command.ActiveConnection = AS400Connection

'Specify Read-Only. This is a custom property
'only for the IBMDA400 object.
AS400Command.Properties("Updatability") = 0

'Set the command to execute
AS400Command.CommandText = CommandText
AS400Command.CommandType = CommandType

'Execute the command on the AS/400
Set AS400Recordset = AS400Command.Execute

If (Err.Number = 0 ) Then

'do stuff

Else
   'An Error Occurred
   DisplayError AS400Connection, Err.Number, Err.Description,
Err.Source, "Main"
End If

AS400Recordset.Close
Set AS400Recordset = Nothing
Set AS400Conection = Nothing
Set AS400Command = Nothing

'*************************************************************
*************************
'***
'***   Subroutine DisplayError
'***
'*************************************************************

Sub DisplayError(Connection,errNum,errDesc,errSource,proc)

On Error Resume Next

    Response.Write("<br>VB Error Number: <b>" & errNum & "
[0x" & Hex(errNum) & "]</b>")
    Response.Write("<br>Err.Description: <b>" & errDesc &
"</b>")
    Response.Write("<br>Err.Source: <b>" & errSource & "</b>")
    Response.Write("<br>Procedure: <b>" & proc & "</b>")

    Response.Write("<br>Connection errors: <b>" &
Connection.Errors.Count & "</b>")
    If (Connection.Errors.Count > 0) Then
       For Each ErrorMsg in Connection.Errors
           Response.Write("<br>" & ErrorMsg.Description)
       Next
    End If

End Sub


Some caveats:  This works best with client access express v4r5
or better on the server presenting the asp.  No ODBC data
source is necessary, but you must install the data access
objects (which install by default)
