View 2 Repliesi have been in state of hectic for the last 2 days making lot of research and finally made this code worked it for me. My problem is that, how can i make this code retrieve the image from sql server database...use picturebox to load it in the vb.net program.

As
String =
"C:myPicturesmyimage.png"

Is it also possible to change the location of image where its getting the image. i mean, i would like to tell other computers to get their images from anywhere as long as it brings images to my server.i mean, say that comp1 which is connected to my database server for storing and retreiving information, gets his image from his location then the application sends the image to my server...the application retreives the image from the server..as simple as that.

I'm using VB.net 2003 Standard Edition, and I'm trying to retrieve the file modified date. I've created a System.IO.FileInfo object, and have collected info from the three methods: CreationTime, LastAccessTime, and LastWriteTime, but they aren't giving me the same data as XP Windows Explorer is.In Explorer, there is a Date Modified field (currently reading 2008 on the file in question), but using the FileInfo methods they return 2007, 2009, 2009.Is there another IO object I can use to get this 'modified' date?
View 1 RepliesWhat is the best way to retrieve the date and time from an online server instead of retrieving from the user PC? Some sample codes I found online can only request to a server which is window based which I can't find any free server to get. I thought of retrieving the value from a website like [URL] but I'm not sure is this feasible or not as their website content or html tag might change.

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]
View 2 RepliesI am attempting to import data in a batch from an Excel Worksheet to a Sql Server database. Everything works except for the one date field in the spreadsheet. The date returned is off by four years from the value in the spreadsheet. Example: The Excel sheet has a date 10/24/2010 14:18, but when I look at the column in my query, the date is 10/23/2006 2:18. This pattern, 4 years and 1 day earlier, is repeated for every row in the worksheet.
The Excel column comes to me as a custom type, formatted m/d/yyyy h:mm. I receive this from an outside vendor and having them change the column is not going to be my simplest solution.
For what it's worth, the relevent part of the query is:
Select [Date Created] From MyWorksheet

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)

Dim response As FtpWebResponse = request.GetResponse()
Dim responseStream As Stream = response.GetResponseStream()
Dim reader As StreamReader = New StreamReader(responseStream)

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.

View 1 RepliesIm taking over a project that pulls information from a database.Currently I have everything I need except the username.The person who setup the project did it as a web project so he used the MemberShip class to create unique user keys based on the person's username.
The username is not stored anywhere in the database only these userID keys.
The client wants a desktop app that mimics the website behavior of writing to the database.
Problem:I ask the user to enter in a username at the login. The username connects to the database on the server.I have no way of grabbing any user info after this point as the primary key(USERID) is a unique key and not a username. Is there a way to convert a MemberShip ProviderUserkey into a string Username or am I screwed?
