When you search on google most of the examples are very vague, hopefully this thread can make it to the top and will help someone looking for the same info.to explain the code what it does is create a long string by concatenating all the values together stores it in the variable finalString and then hashes the string using the SHA5 algorithm. Then its supposed to send the string (finalString) as a post request to the url.The server im sending it to reads it this way and sends a response. [code]
View 1 RepliesWorking on a program that makes use of a third party API. That API can be found here:[URL]I'm a beginning/intermediate VB.Net developer, and have written other programs, but not using something like this. I suspect I'll need to create a Web.Request (Secure) object and 'POST' to the URL with a stream of XML text. That's the general idea, right? The actual URL is internal to our network and I have that information of course.

I have to query once an hour to a remote web server to recieve data. However the remote web site does not use web services and state in thier 300+ page document that:
Although SOAP is a recognized Web Services API, the RTO web server does not offer a web services interface. That is, there is no Web Services Description Language (WSDL) file available for usage by participant web services client software.
So my question is how do send a soap request and get a response without the use of a WSDL?

View 2 RepliesI have two web servers with public IPs, for example Server1 with IP 111.111.111.111 and Server2 with IP 222.222.222.222. see the picture:
There is an asp.net webform at Server 1. My intention is:
For every http request to that webform in Server1, the Server1 just pass the request's information to Server2 for logic processing and subsequently Server2 sends the response back to client (i.e. normal browser)
My questions are:
What information that Server1 needs to pass to Server2, so that Server2 able to send response back to client? note that at Server2, there is a TcpListener instance. This TcpListener instance acting as receiver for that webform request information from Server1. What is the suitable object (i.e. the class in System.Net or related namespace such as System.Net.Sockets) at Server2 for sending response back to client? Suitable here means able to meet my intention.

For example
dim finalurl as string= [url]

I have a 3rd party webservice (happens to be a peoplesoft EIP service) that I'm trying to call from .net. I've tried using a service reference and the old web reference to call this service and every time I call it I get a response of "nothing" back from the service.
I've ran the service call through SoapUI and it works fine. I've captured the network traffic using Fiddler and notice that when i call the service from SoapUi or from .Net I get the same resulting xml back from the call. So that means the call is working. I've turned on tracing and logging within WCF and I'm not seeing any errors. Nor is it throwing an exception.
So my theory is that .net is having a hard time translating the xml from the service back into a .net object.
Here is a snippet of my code:

I am getting an intermittent "System.Web.HttpException: Request timed out." error when my code hits the line response.write():
sMessage = "Searching...0% complete."<br>
sSetVal = "<script>document.getElementById('MessageDiv').innerHTML='" & sMessage & "';</script>"<br>
Response.write(sSetVal)
Note that Response.BufferOutput = false is set when the page first starts executing (well before the above code executes).The code is used to update a progress message while other threads execute long-running processes. One thread runs continuously and checks the status of the other threads. As the other threads finish, this thread outputs updated status messages to the end user. I realise that this could (should) be recoded using ajax, but it is a legacy app and that is not an option at the moment.
This code is run 10,000+ times a day, and the error only occurs about 5 times - so I suspect the response object is being blocked by other threads when the website gets busy. However, I don't know which performance counters to check in the performance monitor. Or is this problem caused by something else? I am using IIS 6, asp.net v2 and vb.net?
I have recently started using Request("key") instead of Request.QueryString("key") to access my querystring values. However I have read that:
'Gets the specified object from the System.Web.HttpRequest.Cookies, System.Web.HttpRequest.Form, System.Web.HttpRequest.QueryString, System.Web.HttpRequest.ServerVariables'
Therefore, if I have a querystring key and cookie key which are the same, which value is returned?
i made a tcp/ip application using the .NET TcpListener class, my problem is that sometimes (about 30 / 4000) the connection between the client and the server got interrupted in the middle and the server response to the client is lost.is there a way to know if the server response was successfully sent to the client without the client response back?

My Request.Form keys are all prefixed with ctl00$container name$ and then the key I want.How can I get the regular key name working?
Visual example from the immediate window:I want to use:

but it won't work because the key is:

so only this works:

I've spent the best part of the week learning about TCP/IP and sockets but it's really draining my enthusiasm for my project. The basics are simple enough and the MSDN examples are fine and I can put together a simple server/client easily now, but once I start getting into asynchronous connections, threading and all the other stuff, I'm getting bogged down and frustrated. I've followed a dozen tutorials and examples now and they're all too confusing and half of them simply don't work.
I think what's most frustrating is that I really don't wish to become an expert on sockets or TCP, which seems to be the advice on most forum replies. I really want to be getting on with my project which has ground to a halt since I started looking into this. Yes, I know the world isn't always that simple.
So, what I'm looking for is a 3rd party app or some working code that will let me set up a server and multiple clients. All I really want them to be able to do is to send strings to each other, without blocking the application. Really, that's it, just the ability to pass strings back and forth between server and client, preferably in as simple a format as possible - e.g SendMessage(Client,String).

I am writing a small application that will display some info to my end user. I have another program that the end user will have open while running my appplication. What I am trying to do is have my application launch itself (and maintain positioning if other app location changes) and "tether" itself to the other application.Ideally the top left of my application would attach to the top right of the other application.I have tried for countless hours working with the GetWindowPos API but the values returned are either all zeros or it just doesn't work.I do a Try/Catch to see if the other app is running and I fetch the Handle of the process. This works fine. Then I try to get the positioning of this process and set my .Left property to the returned RECT's .Left property. no dice.This is Visual Basic 2005 ExpressOther application is a PuTTY window that is not a fullscreen app.
