Is there a way that a vb.net program can log intp, using forms authentication, to an ASP.NET (4.0) website I have with user supplied credentials? By that, I mean I have 2 string values for the username and password and source code for the ASP site. After the user is authenticated, in need to upload a file to an ASP.net FileUploadControl page.Not sure if this is the right place to post this though.

View 3 RepliesI have been reading through Atheists posts in regards to client-server and TCP client/server connection's. But how do i go about writing a program with 1 client and server where the client side creates a text file.Once the server sees there is a text file it connects and downloads it to itself or the client pushes the text file to the server.Once on the server i will read the text file and put its info into a sql db.

Client: [Client is made in VB.NET]
Add new form: "Login Form"
Add new form: "Form2"
[Code]...
if it is "LOGIN" then check is the username and password correct, after that send back to the client that the information is true so the client will show up Form2
if it is "REGISTER" then add new username and password to the server *NOTE: The username and password will be saved in a file
basically i want to create a login to my program which uses the same username and password as windows login.I already know how to retrieve username and auto place it in the username box using
TextBox1.Text = Environment.UserName.ToString
i wondered is there an easy way to only allow access if the password matches up to their logon? i dont know about setting up databases but i dont think this option would work because each member of staff can personally choose their password.
I have been playing around with a chat program - a modified version of Asscotte's P2P tutorial. It works fine using my local address. When I try to login from a different location(and I mean thousands of miles away) I can't get it to log in. My computer is on a router - is that the issue here?.
This is the function I use to get my address.

View 1 RepliesI have been a web developer for a number of years now and I am making the move over to form based applications. I am trying to do what I believe should be relatively simple, yet I have no idea where to start.At home I have a machine that family members tend to use P2P programs, which causes my online gaming to suffer with glitches.I want to create a server and client program.where the client app (on my laptop) consists of only one button, when the button is pressed I want the server app (my Desktop) to kill the P2P program.I already know how to kill/start the application in question.I have previously done something similar but I had used winsock (not in VS2010) and was a long time ago.
1) Sending a value/string from the client app
2) receiving the value/string on the server app
I was told to look into the system.net.sockets namespace, but I haven't found anything on the web or here that isn't a full project / over-engineered "Basic Tutorial" that helps to break this down

View 1 RepliesI am trying to create a server/client program in vb.net. What I am trying to do is test a battery that is running on a handheld (which runs Windows CE 5) by connecting to a "server" and sending information every 10 seconds or so. I am very new to .NET, and am not really sure how to go about doing this. I want two separate applications running, with the server-side keeping all of the data, since the battery is going to die, and I will lose any information if I keep it client-side. I am also new to networking, so I was not sure of whether I should create a Socket, or if I should try to do something else.

I'm trying to make a Client that will automatically run a .DLL that I have created and send information over port 80 to my Server program that will take that data and import it into a database for me. Problem is, I don't know where to start as I have never done this before. I want to do this in VB .NET as this is the programming language that I know. What are methods of doing this? Is there sample code out there for something like this? My google searches are failing me.
A better layout of what I'm trying to do:1. Client Runs .DLL, retrieving information from an Excel file.2. Client takes these properties with the data it contains and sends it to a program outside of the local network through port 80, my boss refuses to let me use any other port.3. Server accepts the data and builds its own properties to be imported into my Access Database.4. Repeat over, and over, and over, and over.
I plan for the server application to be a console application, and the client to be a windows form.
I've created a multithreaded application that copies data from one directory to another, and I'm having trouble getting it to work properly on clients' computers. All computers running the software have Windows 7 and the .NET Framework 4.0 Client Profile installed, which is what I've compiled the program for. I have two threads: one does the actual copying, and the other updates the UI on the program. Whenever I run the program on my computer, even if I'm copying 45 GB, for example, it runs fine. However, if I run it on another computer, it will sometimes freeze the entire computer, so then I have to manually shut the computer down in order to use it again. I have been trying to find out why this occurs, but I cannot. Does anyone think he/she can provide me with some ideas as to why this happens and how I can prevent it from occurring?
View 4 RepliesI am trying to code a client - server program. I have 4 winsock controls on my main form. The client is able to connect to a free one just fine, and can figure out if they are all in use. When testing my program, I found that when I try to send data through a socket, then send different data directly after, it jumbles the data together.
CODE:
That is the code I am using. When the client is connected to the server, and ready for data, it sends the packet "@Ab". When the server receives this packet, It is supposed to send the welcome alert, and then current events posted in the server.
On the client side, there is a message box that is supposed to show the welcome alert, and at the bottom on a status strip, the current events are supposed to be listed.
When the welcome alert shows, it contains the alert text fine, but then shows the packet for the events after it.
