Passing Current User Credentials From IIS Server To Reporting Services Sever?
Aug 8, 2011Question: How to pass the current user on the web page from the IIS server to the Reporting Services Server.I have seen this topic throughout the forums. However, the answers are always hard code the user in web.config - use a login window and pass those fields to the IReportServercredentials or create one user for everyone.
When the person who asks the question comes back and says that doesn't work there is not answer.Does anyone know how to do this? I have VS 2008 ( and 2010 ) I am sending the info to SSRS 2005 server.As anyone using SSRS knows that if the reports have parameters and udf behind the report to inspect who the user is, then you have to pass that user to the report.
[Code]...
I have been programming steady with vb.net for a year now and was all happy about using the List view and email etc from web sites. I even used a reportviewer to pdf to email attach, cool. Now I feel quite lost and realize I have not been using properties, etc. That is my background.
Download From FTP Server WITH Credentials?
Jun 10, 2012I want to download my update files for my program from an FTP server, but i need to login first with the credentials. I have tried many things, used some examples on MSDN, googled a lot, but i can't find the code that i'm looking for... I also use a DLL of someone that i've imported into my project. I don't know if that harms my part of being unable to log in.
I have ZERO experience with FTP servers or Network Credentials, i've learned the little things about it on google.

Storing User Network Credentials?
Nov 1, 2011We don't want to get the password, we only want to store the user credentials so when they do work on the application we can apply their usernameto each operation and when they are done with an operation and do a digital signature by scanning their badge we want to compare the user's credentials with the stored credentials to ensure the user has logged in and is the current user.1. User 1 logs into the program using their username/password for windows.5

ASP.Net (IIS 7.5) Querying Active Directory Without User Credentials?
Dec 20, 2011I have multiple web applications that I've built for our intranet. I wanted to allow users to not worry about logging in, so these apps pull the currently logged on user when they hit the site. I used this code for this to happen:
Dim userName As String = User.Identity.Name
CurrentUser = userName.Substring(userName.IndexOf("") + 1)
This works like a charm, no issues here. The next step is to query Active Directory for that logged in user to pull various information. How I currently have it coded, it works like a charm on the devleopment side (typical because I'm not running IIS).The problem becomes when I publish it to my IIS server (Windows Server 2008 R2 running IIS 7.5), I get error messages that point to the specific line in my code that queries Active Directory. The interesting part is these apps were working great last week. They broke after my server admin did the latest batch of Windows Updates (please note, I am running them using .Net Framework 4.0)Before I had each app setup so that Windows Authentication was Enabled, the other Authentication types were disabled. For providers, Negotiate is #1, NTLM is #2. For Advanced Settings, Extended Protection = Off, and Enable Kernel-mode authentication is checked.
[code]...
In doing this I also removed the string that was higher up in my web.config section. This did not work either (fyi, this was a great reference[url]I then tripped across this article: [url] which seemed to be a similar situation. This article eventually referenced "Double Hops", after looking into this and trying a few things, this didn't solve my issue either.Next StepI am going to try a new IIS 7.5 implementation on a different Server 2008 R2 system and essentially start from scratch, to see if the problem recreates or not.
Prompt For User Credentials On Program Start?
Feb 11, 2012I'd like for my application to prompt for user credentials as soon as it starts. The reason for this being that it is an app for our IT Helpdesk that will be run on user's machines, and I need to make sure it is always run with administrator credentials.
Is there a simple way to get the program to prompt for credentials on execution?

View 1 RepliesUse VB Form To Supply User Credentials To Runas Command In Prompt?
Sep 28, 2006Is there any way to use a VB form to supply user credentials to the Runas command in command prompt? I basically need something exactly the same as the GUI for RunAs but just for Internet Explorer (yes I know you can right click and go RunAs but that cant be done in this case). So the user would open this VB form, type their username and password in, hit OK and it would open Internet Explorer with their credentials (they log in under a generic account used by many people).

View 1 RepliesVS 2010 Client-Server Communication On LAN?
May 12, 2011I'm doing a small project. It works on a LAN. The working of the project is:In client side, a user would enters "username" and "password". It would sent that to the server, along with the time.The server would authenticates info on checking a db and writes some info to the db.Also, the server should be able to sent some commands or instructions to the clients.These commands on received by the client, it would invoke certain functions/subs on the client based on the command.So, would it be better to use TCP client & listener or WCF ?
View 6 RepliesClient/server - Can't Access Communication Variable?
Aug 14, 2011I have a client/server program. There is a variable called readData that takes returndata and places it there. My question is, why can't I access this variable directly, for instance, varC = readData and then try to access a piece of it i.e. textbox1.text = varC(2), I get an error "object reference not set to instance of an object". Why is this happening? It is because the readData is a networking 'component'? How do I get around this? I can post more code from the server app if needed.

Named Pipes Or TCP For Client/server Communication?
Oct 4, 2011The client/server communication will only take place in the same network.I can use TCP, but then I have to configure separate IP ports for every server instance. I can however simply use named pipes so I don't have to think about port numbers and simply use the name of the server instance.There will not be very frequent and/or large data client/server communication. It's some sort of a ERP application that will only communicate once per 30 seconds on average.

It successfully "connects" but then immediately disconnects.Here is the code for the server:

I have port forwarding all done and it works if I run the client and server on my own machine. If I run the client on another machine though It gives me a message box saying that it connected with the clients remote IP and at the same time it tells me it disconnected. The client never sends the system information. What is the problem?
