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?

I 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.
I am sending xmlhttp request to a web server with parameter, and wait for the response before I send another request. About 98% the application is working fine, except if the internet speed became suddenly slow or there is a delay from the web server i am dealing with.
here is how I am doing it,
Public _xmlHTTP As New MSXML2.XMLHTTP <-- declared in a module
Function SendRequest
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]

My intension was to have an easy to browse program with links in the program which open the particular file (eg.

Private Sub btnProgTemp01_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnProgTemp01.Click

I am using a client.openRead to send request and passing line through finalurl.
Dim data As Stream = client.OpenRead(finalurl)
Now my server blocks ports and i am getting error on this line now is there any other solution to client.OpenRead and what ever i am sending throught this is code is going on other company's server so i can't tell then to change their way so is there any other solution to this?
I AM THINKING THAT IF PORTS THEN IMPOSSIBLE TO SEND REQUEST.SO ONLY WAY IS TO CHANTGE SERVER WHER I HOST MY SITE
Dim data As Stream = client.OpenRead(finalurl)
And in final url i have other sites url and some querystring data
For example
dim finalurl as string= [url]
I already use WebHttpRequest but it not works still server not allow it.But i try it with response.redirect and it works but not suiteable to my conditions.i want control on my site so i was using Dim data As Stream = client.OpenRead(finalurl) but now server block some ports due to some reasons

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?

ok here is my problem, im making a little app for school since our school blocks pretty much everything so here is my plan a student makes 2 gmail accounts one for school one at home.
in the program at school (client) they put a site request into a textbox and they hit send, the request is then sent to the home pc gmail account and another app on the other side downloads the full site that they have requested and then sends them an email back with an attachment of the complete website, it is then opened in a browser and they have the site, simple idea and it would be easy except.
my school blocks the smtp protocols in vb, even outlook cant use gmail accounts only the schools registered email, however, you can access gmail on the internet without any blockages and you can send and recieve on the gmail website.so how can i use a webbrowser control to log the user into there gmail account through a custom gui, and send a string like www.facebook.com to the home pc gmail account, and then use the web browser controll on the students laptop to recieve the response email through a web browser, is there some kind of gmail api i can use?

View 15 RepliesI have a program that is using API's to send mouse events and keyboard events to another application that is running. I need to know how to tell if there are any messages left to process for that window after I have click on a button or moved to the next field. I need to know this so I don't send any more mouse or keyboard events until it has finishing processing everything in its message queue. An example is that I click out of the key field and the form has to go out and read a client record. This may take a second or two, so I need to wait until the form is ready for more input.
