I have a website that was written in VBSCRIPT that I am moving over to VB.NET. Until I have time to get to rewriting some pages/applications,I would like to update some of the code so they work a bit better.I am trying to grab a server variable on the VBSCRIPT page that contains our username from the enterprise login.I have 2 test pages here, one with language="VB" at the top and the other language="VBSCRIPT".
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title>Server Variables</title>[code].....
The VBSCRIPT page will list variables with no data when they have data on the VB page and in ALL_HTTP. Is there any way I can get VBSCRIPT to gather the correct info for all the server variables?
EDIT: These are the variables that vary between VB and VBS AUTH_USER, REMOTE_USER - logged in user on VBS, iis_anon on VB REMOTE_PORT - not listed in VBS
The following are listed in VBS, but have no data
HTTP_SERVER_PROTOCOL
HTTP_SM_TRANSACTIONID[code].....

I have Memberships and Bookings tables in database containing an attribute cust_id which is primary key in Memberships and reference key in Bookings. When i am executing data reader I want it to read cust_id values from membership table but it is reading it from the bookings table. Also when i compare two cust_id values, 1 taken from a textbox and the other taken from database column, even though both are same but the comparison result is false. I have compared using string.equals(str1, str2) and have also compared the two directly using if statement but in both cases even if the string is same but result is otherwise. [Code]

I'm using this code to retrieve the list of files from a FTP server
Dim request As FtpWebRequest = WebRequest.Create("[URL]")
request.Credentials = New NetworkCredential(username, password)
request.Method = WebRequestMethods.Ftp.ListDirectoryDetails
Dim response As FtpWebResponse = request.GetResponse()
Dim responseStream As Stream = response.GetResponseStream()
Dim reader As StreamReader = New StreamReader(responseStream)
messagebox.show (reader.ReadLine)
It gives me alot of information that I dont need, I know that I can use:
request.Method = WebRequestMethods.Ftp.ListDirectory
Which only retrieves the file name but when I try to change it, it gives me an error. Error number 550. ListDirectory so I can only get the file name?

View 1 RepliesIs there a way to set session variables during login that are then available to reports? We have a reporting services server where we move and denormalize data from our transaction system for reporting purposes. In order to allow our users to login with the same user name and password from the transactional system we have set up custom forms authentication and after much trial and error it is finally working. In addition we have the authorization accessing our transactional system so that any changes in user authority is immediately reflected in Reporting Services.
Our problem now is that we would like to add some additional features such as locking down parameters depending on user authority/groups in our transactional system. We have found a way to do it but it's inefficient, basically we have stored procedures that will query our transactional system to check for access. The problem is that these queries will often be run for every report request even though the answer is unlikely to change. It would be nice to have access to session level data that can be set once during log in and then accessed from the reports.

I am doing invoicing using VS2008 VB. I use Crystal Reports to produce the invoice. I create an in memory dataset to pass to Crystal Reports. What I would like to do is save the dataset I sent to Crystal Reports as an audit trail of the exact invoice. It would only be retrieved in the event of a dispute concerning the original invoice. I thought of using the WriteXML, ReadXML. But that would overwrite the existing XML. Does anyone have a better way of saving the XML for future retrieval?
