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:
[code]...
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?
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?

i have this to basically complete a form i used getelementid but it never completes i think its due to the form type, on my first button in webbrowser1 i have similiar code which logs me in and it works fine although this form is a <form id="form" enctype="multipart/form-data"> form, should this stop me from completing it with .innertext ? due to the enctype? i would also like to be able to user innertext and take it from a TextBox9.text
how do i get around this to complete these values, my code shows no errors it just navigates to the page and dosent complete anything, button1 logins fine and the code is almost identical, except for obvious differences http address etc code edited slightly posted old unfunctional version, this is now what i have, still unfunctional but makes more sense i think

I'm trying to send some data onto a server. The data is an XML in form of string and and image encoded to base64.The problem is that the server says '404 Not Found', just as if I had an incorrect URL, but my URL is 100% correct. I can get data from the server using GET, but when I try to POST it doesn't work.I checked it in Fiddler and it first gets z 401 error (not logged in) and then the 404 error, which results in an exception.Can anybody please have a look at the below code and tell me if there is something I'm doing wrong?

I have a bit of strange behaviour in an asp.net web application that involves the session state being lost.
Process A user logs into the application and the session is set. They then fill out 1 field, and the application then does an AJAX POST to a .asmx web service. Within the web service, I am using a HttpWebRequest to grab data from another server.
This data is then output to the browser.A few more fields are then filled in, and the data is then again Post to the same web service via an AJAX POST.

The below code allows me to login to a site using HttpWebRequest however I can't login to the site [URL] (which is the one I want to login to). At the bottom of the code I write the source to a file and upon opening it simply shows the login page.
After looking at the source I believe the issue is caused by the form calling a javascript funciton to actually submit the form when the 'Login' button is clicked. Has anyone had this type of situation in the past and if so what was the solution to get the form to submit?

This is the short instruction:
1) Make a single HTTP-POST request to the following URL in XML format.
[URL]={password}&user={username}
2) The xml form field that is posted should be named "createorder".
I don't get the last part with naming the xml form field. What the xml form field means (stands for) in this context?
I've written my HTML webserver in VB.NET and I don't know how to make it read data values submitted in HTML forms. My web server only responds to HTTP 'GET' requests. My sample cod is below it is reading the URL rather tan the data contained in the forms`

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"];

View 1 RepliesI 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?
