Use Post Data Instead Of A Web Browser?
Feb 12, 2010
I am creating that will use Post Data instead of a web browser. I am new to post and this is my first time using it. I decided to go with something easy, and just make a program to auto login to Facebook. When I try it out it doesn't log me in. There are no errors or anything, just doesn't work. My code is below if anyone wouldn't mind checking it out to see what is wrong.
Imports System.Net
Imports System.IO
Imports System.Text[code]....

i'm trying to do away with webbrowsers (IE required) from my vb project.
also whats a better alternative to ie browsers in vb.net, i been looking at gecko but people say it requires you to include 16mb+ worth of files?!?
there must be a way to include browser functionality, without the end user required to have IE Browser?

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'm currently working on web application using VB in ASP.NET.Right now I have 1 page with panels that we are using to show/hide depending on the flow. When the user first comes in, he/she is presented with a gridview containing a list of clients. Then the user, clicks a link from a row and is presented a form where he/she can update the clients' info.Originally, I had a HYPERLINKFIELD that put the clientId in the url, then I'd grab the url and do the code appropriately
<asp:HyperLinkField Text='<%$ Resources:Resource, ManageClient %>' DataNavigateUrlFields="CLIENT_ID" DataNavigateUrlFormatString="~/clients/manage.aspx?clientId={0}" />

I am using ASP.NET.
There is a system that needs to POST data to my site and all they asked for is for me to provide them with a URL. So I gave them my URL [URL]
Now I do not know exactly how they POST it but now on my Test.aspx page I need to write code that will save that data to a database.
But how would this work and what must I do on my Test.aspx page?
I wrote some code in my Page Load Event that sends me an email on Page Load to see if they actually hit the page and it does not seem like they are even?

Is there a way to intercept POST data like HTTPAnalyzer?Can I make a call to send the data, see how it's formatted but actually block the connection if I know where it's coming from?
My goal here is to replicate the sending of an email through an SMTP server.

I have the following code which I mashed up from several sources:[code]This works great until I add another POST parameters to query, like "client=mgdf&version=100".No errors are thrown, the program doesn't crash, nothing. It simply stops working. How can I POST multiple values to my server?

I have kind of a big quesstion...ok here goes...Usually if i understand it well...web services work in a way that i write a method to get some data from the database and then some other user/client adds a reference and calls my service and gets the data...now in my case i have to get the data and actually post it to the user/client in xml(in soap maybe) i guess....so here is what i do...
[Serializable]
public class MyClass
{ [SoapAttribute]
[code]....
So basically....I serialize it to xml(and soap) and convert it to string and then upload this string to the web service url...I just want to know if what i am doing is right?...i want to basically get the data convert it to soap xml and then send it over to the user's web service url...

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?

I am creating a program that will assist users upload a file to a couple different upload sites. There will be RapidShare and Uploading. I want to keep the GUI clean and simple, so I do not want to use a web browser. I have not used much Post Data, but am wanting to use it for this job. What I want the program to do is after the user specifies a file, the program will automatically upload the file to the site.
Here is what I have so far:
Public Function MultiUpload(ByRef data As String, ByRef url As String) As String
Dim request As HttpWebRequest = DirectCast(WebRequest.Create(url), HttpWebRequest)
request.Method = "POST"
WebRequest.Create("[URL]")
request.ContentType = "application/x-www-form-urlencoded"
Dim postData As String = data
request.ContentLength = PostData.Length
request.ContentLength = PostData.Length
End Function

I use Visual Basic.net to create a program that connects to several websites, logins, then post some data. I can't use the httpwebrequest, some java is required on those sites, so i use the webbrowser control.Now I created a form, some fields for input data and a submit button. The coding part is like this:
Code:
sub website1(vars)
'login here
'post some data
[code].....
The problem is that I can't control what happens after submit button is clicked. I need to pause or stop the process at any time. If I exit the program while processing, I can see that even if the window disappear, the program is still running!I tried to use a thread for this, but the subs only get called if I use begininvoke, or invoke on a starter thread.

Can I Post a Windows Application that uses Excel for live data calculations? Basically from the Windows app, a user makes a menu selection and which in turn opens an excel file in memory using it for calculations. These files are put together by different groups and formatted for the Windows app to build interfaces based on each file.I also accompany an .mdf file as well. Is all this possible for customers to access and run this with Windows Azure.

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.
