[2008] Send POST Data To Current Webpage In Webbrowser
Mar 1, 2009
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)
Now I just need to figure out how to press the submit button

I've code this code below:
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim hwrRequest As HttpWebRequest = HttpWebRequest.Create("http://www.example.com/web-service.php")
[Code]....
The MsgBox() at the end shows the response, which as I've added to my script, echos the result from the $user and $pass variables which are supposed to retrieve those details being written to the stream above, but they show up empty.
I'm retrieving those values by doing: $user = $_POST["user"]; $pass = $_POST["pass"];

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 wanted to display my current logged user data in my aspx web page.But I am unable to do so. I just can't understand how to call the necessary data. I have used Grid view but I cannot find a query that will give me the details of the current logged user.
Code:
HttpContext.Current.User.Identity.Name
but it gives me an error saying "property access must assign to the property or use its value". I don't know how to tackle this.

I'm instantiating a WebBrowser object and programmatically clicking a button to navigate. Is there a way (property, method, or voodoo ritual) for me to check the browser after it lands on the new page to see 1) the form method that was used and 2) the post data?

Quote:
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.
Note: you must still create each forum's account manually.

I'm attempting to populate fields in a processing webpage [URL] and having a small problem.
I can add the email and antenna heights easily but how do I manipulate a file browser (file upload) and option input boxes (Antenna Type) from within my vb app?
It might be the long way around but i'm doing it via searching each of the html elements to find the named fields I'm looking for:
Dim intWork As Integer
For intWork = 0 To WebBrowser1.Document.All.Count - 1
strWork = WebBrowser1.Document.All.Item(intWork).Name

Here is the

I currently have a simple VB.Net WebBrowser program uses webbrowser control, I 'd like to have certain data returned by a sever in the open web page send to the VB.net program, i.e. retrieve the html response from ASP.NET page.
i need to query a database a user's Full Name, when data is returned by the sever side script, it won't do any update on the web page, instead it should notify the VB.net program what users' full name is.

I designed a complicated graphic that draws on a Visual Basic screen. But how can I transfer the image to a bitmap or some other format that I can post on the Internet? I've tried the XAML editor in Microsoft Expression Web but people don't like downloading Silverlight, at least that's what they tell me.

I was wondering, if there is a way to use httpwebrequest post method to send data to a PHP function directly (no forms, or whatever)
so for example, i have this PHP function, which writes to a file:
<?php
$File = "textfile.txt";
$Handle = fopen($File, 'a');
[Code]....
Now, i have a form which would usually post the text which should be writen, so, can this be done directly, without that form, using httpwebrequest in VB?

I am trying to post data to a multipart form. The problem right now is that I cannot determine the boundary of the data. The only way to find it is to actually POST some data (as far as I know). The boundary also changes each POST for a single static page.Is there a way to find the post data boundary?

The form I want to post to has a dynamic boundary.Is there a to detect the boundary pre-POSTing?Also, do I need to send the data in the format of:

Or can I set it up in pairs like: "var1=value1&var2=value2"...for all required form fields? What is the difference between the 2?

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've managed to narrow down my issue to a simple annoyance. I had a Webbrowser control mostly coded to navigate around an Oracle CRM On Demand site to generate metric reports, but then realized when I tried to build in the auto-download part, that the Webbrowser object wasn't going to give me the behind-the-scenes control I wanted. Searching online, it seems the Webclient control might be a better route. However I'm stuck trying to get by the login page so I can use the Download-File method to get my generated xls report. [Code] But every reply from the server has "Sign In Error: Both a user sign in ID and a password must be given." which tells me the form/post data isn't getting where it needs to go (It thinks the form is blank at [Code].
The above username and password are bogus of course, but once I can get a different reply then 'the fields are blank' I can worry about correct logon information. I'm just not sure what I'm not doing correctly or if I need to include something else. Since it's a publicly accessible site and I'm stuck getting something in the form to be 'seen', it should be easy for others to try and test.

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.
