I need to write a quick function that sends two data items back to the UI thread... with the post/send commands I only see the ability to send one piece of information. Is there a way to do this by overriding these functions?
View 3 RepliesVB.NET 2010, .NET 4This might be a dumb question but I'm wondering what is special about the SendOrPostCallback delegate that is the first argument in indowsFormsSynchronizationContext's Send and Post methods? In other words, I can do the following:
SyncContext.Send(Sub() ..some work.., Nothing)
And that works (SyncContext is a WindowsFormsSynchronizationContext object). Why might it be preferable to do:

What is the VB.NET (or C#) code to prepare POST data and send to a different website than specified in the current <form ...> section?
EDIT: Every algorithm I've found online using HttpWebRequest gets the returning page from the other site and outputs it with Response.Write. I want to navigate to the new page posting the data and leaving the current page completely.
EDIT2: (more specific description of what I want)The code below displays a line chart. When the user clicks on the label for a data point, the page refreshes (performs a postback) and displaying the x-value of the clicked point.Instead, upon clicking a label, I want to send other_id="#VALX" as the only POST data to other_results.aspx as if the user had typed the corresponding id into the the TextBox on other_search.aspx and clicked Submit.

How would I go about sending POST data to a PHP page? For, example, if I used this as a PHP page.
<?php
$User = $_POST['User'];
$f=fopen("Login.txt","a");
[Code].....
And, a form with a TextBox, and a Button, how would I go about sending the contents of the TextBox to the PHP using a HTTPWebRequest? I don't need to receive any data back, just send it.

I am trying to send a POST request to add some content to an API box. The rules are that the body format should be XML(values must be XML-escaped), HTTP Method (post), requires authentication(yes), request content(content-type: "application/xml". [code] Best practice is to incrementally add and remove changes to your entry list instead of deleting/recreating the entire list each time a change is necessary.New entries are placed at the top of the queue for polling and are processed in a LIFO manner.

View 13 RepliesHow can I send a POST HTTP request to a server (in Visual Basic 2010) and then receive the reply into a string.
View 1 RepliesI have used the WinHttp.WinHttpRequest object in VB6 to make HTTP POST requests many times. It works great: .Open the URL, then .SetRequestHeader (however many are needed) and then .Send the body. The .Send method makes the actual connection and sends everything to the server at once.How to I emulate this behavior in .NET? The examples I've tried with System.Net.HttpWebRequest open a stream with .GetRequestStream() and then write the body to the stream. Unfortunately, the server is responding immediately to the .GetRequestStream method and therefore never sees the POST body.I am obviously trying to connect up some legacy stuff here, but am having a hard time Googling the problem or finding another approach in .NET.
View 2 RepliesWhen 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]

This program posts inside many forums (you can choose). It's main objective is to allow a user to distribute their posts to many forums easily without opening each individual page on the in a web browser therefore you get more points to your filehoster's account.

I am trying to send an HTTP Request to a server using a POST method. The problem comes from the PostData, which needs to be in Bytes form to be used by the UploadData function.

I wanna send POST data to the current web page viewed in my webbrowser. It's for logging into a page so the fields are "Username" and "Password". And then I might have to make it press the "Log in" button?
EDIT: It was easier than I thought when you don't need to do it silent in the background.
PHP
WebBrowser1.Document.GetElementById("username").SetAttribute("Value", txtPassword.Text)WebBrowser1.Document.GetElementById("password").SetAttribute("Value", txtPassword.Text)

I have written a vb.net desktop application for pipe collectors and one of the requests that seems popular is to be able to post pipe details (text) and an image of the pipe onto the user's facebook wall.
Basically the user will bring up their pipe details of choice and be able to click a 'Post To Wall" button which would then post the pipe details onto their wall.
I'm trying to update the UI from a background thread without invoking the control. Mainly because I've tried to do so and it never worked from a class. It worked just fine within the form class, but froze up in the class. I didn't receive any errors, it just lost its multi-threaded-ness.
I'm having a similar problem with using the SynchronizationContext class. I made a quick example to test if this would work how I think it should:

There's very little information on MSDN about this class in general and every example on the web I've seen so far, has nothing to do with classes.

I need to create a "post office" program that will send html emails thru the system.net.mail framework.
For each job submitted to the postoffice the app would need to read a user created html email string from the database, read a string of email addresses to send to and send out the emails based on a set processing time.
The first step would be to parse out the email addresses to find out how many emails it needs to send out and determine how many it would need to send per minute to complete the job in 20 minutes tops. I.e. if 1000 email addresses are submitted per job it would determine that it needs to send 50 emails per minute to complete the job.
The part I am stuck on is how I should queue the emails. If the app determines it needs to send 50 a minute should I only load up the first 50 on a timer event then get the next 50 queued up for the next timer tick? Or would it be better to load up all 1000 in a loop and build in some kind of wait time after it sends the first 50?

Now as you can see it is sending the textbox1 text and then pressing enter then sending textbox2 text! Theres quite a few problems in that but before i discuss note: This code is in a Timer. Problem #1: It does not send the keys fully correct all the time because its trying to send them all at once! So i want it to send them 1 letter after the other with 200 ms sleep in them! Problem #2: The sleep is not working: The reason i know is because even after it did the first textbox1 text it didnt wait that 2000 ms!
Are there any good books out there that will show someone how to set up a form using Visual basic that will take information and send it to the server and then send a recipient an Email?

I am trying to send keys to a control on my form. But I am getting a NullReferenceException and I don't know why. The code is about as basic as it gets: [Code] The error reported is object reference not set to an instance of an object but Send is a shared method so doesn't need an instance. Strangely if I ignore the error it works fine and F4 is passed to the control. I know there was an issue with sendkeys and UAC but I thought this had been solved (I am using 4.0 framework).

I am trying to use the send keys function to send text to another program.I ahve gotten it al working well, except for using () as I know sendkeys doesnt like these.I have tried using the Replace function in several places in my code to replace the ( with {(} and {+0} etc, with various other options tried.But when I run the program, it seems to skip this out completly and leaves them in the string as (, and therefore it errors and wont run.When I step through it, it goes through the function but doesnt alter the strng as it should.
