View 11 RepliesI would like to make a vb .net application that auto logs into places and retrieves data from them. I have already succeeded in doing this by opening internet explorer programmably and tabbing to enter name and password. But this is messy, and needs to be well timed. I'm using VB .Net. Is there a way to interface with sites to auto login. Maybe I could inject a cookie, but then the browser could change.
View 4 RepliesI am trying to create a small application that will tell me if a website is up and running. This application will monitor if the site goes down. The problem is that there are several websites sharing the same IP address, and I cannot use ping to monitor it for the same reason. I do not know what type of code can I use to query the availability of the website. I read about webRequest and webResponse but I do not know how to get the response information that will tell me if the site is up or down. The code should be able to tell if a site like "mundo.reporters.com is accessible. That is the only thing.information to point to a potential solution will be more than welcomed.
The server is hosting 8 websites that share the same ip address, and I need to constantly monitor if they are functional.
I'm trying to create a website that can help a user purchase items from other websites. What would be the best way to go about doing this? I know most of the sites I'm using are sending their information using FORM:POST, but I'm having trouble finding the exact POST packet in fiddler (I'm assuming it's encrypted?), and know that a lot of the sites are using login credentials, so that complicates things a bit.

My need is to login a website and submit a message form programaticaly using vb
I have done this partially. I have tried submitting an open form..( which does not require login) and thats successfully submitting my POST request by using following code...But my need for the hour is to login first and then submit the form..If i try loggin using this same method, how can i use same cookies/headers to make further requests which needs cookies etcto post on that message form..
Code to submit open form is:
private string PostData(string url, string postData){
HttpWebRequest request = null;
Uri uri = new Uri(url);
request = (HttpWebRequest)WebRequest.Create(uri);

I need to POST a HTML form to a 3rd party website (a Mass-SMS texting system).
In the past I've done this by forwarding to a page containing a form I've pre-populated and hidden (using display:none), then I've ran a javascript function at the end of the page to automatically submit this form.
However I'm hoping theres someway I can do all this programmatically (as I don't care about the response, and the user doesn't need to see the page the form is being posted to).

View 1 RepliesHow do you save an html table built programmatically in a .html file?
View 13 RepliesI need to create a VB.net app that automatically reads a html table. It should connect to a web address (eg "[URL]") and read it. I'll be happy if I could just get the full HTML. I was able to use this code to get the HTML of a regular website:
Dim strReply As String = "NULL"
Dim objHttpRequest As HttpWebRequest
Dim objHttpResponse As HttpWebResponse
objHttpRequest = HttpWebRequest.Create("[URL]")
objHttpResponse = objHttpRequest.GetResponse
Dim objStrmReader As New StreamReader(objHttpResponse.GetResponseStream)
strReply = objStrmReader.ReadToEnd()
This code sample will give me the HTML for the website [URL]. However it will not work with the website I want (eg "[URL]"), because when you access it via regular browser it will popup a browser dialog asking for credentials (user / pass). So when I run the code above for it, I'll get the exception:
The remote server returned an error: (407) Proxy Authentication Required.
How do I set this up to use the credentials, before retrieving the HTML? This is actually my first web-related app.
Eventually, I'm going to want/need the program I am creating to either:
A. Access the MySQL database from my website.
Or.
B. 'Load' a PHP page, and grab the contents off of it. [URL]Are these options avaiable in VB.NET ?
Code:
Public Function ScreenScrapeHtml(ByVal url As String) As String
Dim objRequest As WebRequest = System.Net.HttpWebRequest.Create(url)
[code]...
If it cant reach a URL it will give me this error:
Code:
Webexception was unhandeled:
Dim sr As New StreamReader(objRequest.GetResponse().GetResponseStream())
How I can add some error-handling to this code? Like if it cant reach a URL.
I have a website that divided into 4 frames. I'm trying to create an application that will constantly run on my PC as a task looking for certain text in the HTML in a frame.When it finds the text it would alert the user by presenting a pop-up message. This is basically a monitoring website that checking network nodes. Instead of staring at the screen looking for critical messages I would like to be notified when there is an alert.

Like in firefox or Internet Explorer where you can right click and view the html page source how can you do this in an app?I have a web browser in the form and I'm trying to view the web page in the web browser and then view the source code of that page in a box below it.

I am trying to extract everything between the body part as I am building a forum crawler
and since all the user posts are between the <body></body> I have chosen to experiment
with Regex. So far I have coded the following but sort of stuck on how to output the result say in a textbox? Also I am not sure if the body part of the regex is correct.
Dim URL As String = Textbox1.Text
Dim request As System.Net.HttpWebRequest = System.Net.HttpWebRequest.Create("URL")
Dim response As System.Net.HttpWebResponse = request.GetResponse
Dim streamReader As System.IO.StreamReader = New System.IO.StreamReader(response.GetResponseStream())

So, in this program I added 2 necessary login codes let's say, first a code that I will provide and then the username and password from my website. I implemented both ways, the first one worked perfectly, however, the second one is giving me some problems, my idea for that control was not using a database of users, that was going to be too complicated for a 14 year old guy, so I decided to take the source code for my website and I took a fragment, the boxes for the login, username, password, forgot your password, remember me and some other boxes, great, that worked perfectly, I uploaded the HTML modified document to my website's files and linked it to the URL of the webbrowser control in one new form, good, it's working, but I wanted a simple condition that works for this function "When the webbrowser loads the success website, hide me and show the past login form, when this one shows the failed login, popup a messagebox that says the error.". I have been looking for that simple condition for a long time. I am using Visual Basic 2010 Express Edition.

I have a multilingual company website (Visual Studio / VB / ASP.NET 4.0), and when, on the homepage, you click a flag, the text changes to that language and stays with you the entire session, after I made a class, BasePage.vb. Everything works great, but the URL never changes .... clients.aspx remains clients.aspx although the text DOES switch to Dutch.
It's been recommended by @Aritstos to make it so it looks like clients.aspx?lang=nl as opposed to just clients.aspx in another language.
Currently, my asp homepage hyperlinks that work look like this:
<asp:LinkButton ID="LinkButton7" runat="server"
CommandArgument="nl" OnClick="RequestLanguageChange_Click"
class="flagbutton">

I have tried a few things like converting HTML to XML and then using an XML navigator to get input elements but I get lost whenever I start this process.What I am trying to do is to navigate to a website which will be loaded using textbox1.text.Then download the html and parse out the input elements like . username, password, etc and place the element by type (id or name) into the richtextbox with the attribute beside the name.[code]Any clues or how to properly execute an HTML to XML conveter, reader, parser?
View 2 RepliesThe info i need extracted is formatted:
<TD><A HREF="http://xxxxx.com/xxxxxx/index.html"><IMG SRC="../xxxxx/thumbnails/xxxxx.jpg"> </A></TD>
<TD>=== <B><A HREF="http://xxxxxxxxx.com/xxxxxxxx/index.html">LINE 0</A></B> ===<BR>
<FONT SIZE="2" COLOR="#400080">

how do i extract the info between TD=== and /a and Line 1,2, and 3 and store it into a database from a live website?
This may sound really stupid but I have to ask cause I'm not finding this answer anywhere.I have an application where the user will need to sign up for a new user account on the website [URL]..However when I am using Firefox's plug-in Firebug to view html I am getting something totally different than when I just right click on the site and view the page source.
What I am trying to do is to get the captcha from the website and display it in a picturebox on the application so the user can view the captcha, solve the captcha and then the app post is back to the service for a response.
Here is the source that I am getting using Firefox's Firebug to inspect the element:
<td>
<input type="hidden" value="Oo3Jo1I8bgzK68agMqo3s79ZZib2OkbK" name="iden">
<img class="capimage" src="/captcha/Oo3Jo1I8bgzK68agMqo3s79ZZib2OkbK.png" alt="i wonder if these things even work">
</td>
[Code]...
Why would the two be showing me two different versions of the HTML?
And how would you be able to grab that source to view in a picturebox using webclient?
Usage: Users create pretty HTML news letters in another app. They post the newsletter to the web, but they also want to set the contents of the HTML news letter file as the body of an email and send it using Application In Question. The users understand to use absolute link and image references when sending an E Newsletter. Environment:
AIQ is a VB.Net app deployed via ClickOnce. It is an intranet app; one can be sure MS Office 2003 and the interop 11 dlls are on the target machines.
Restrictions: MAPI is out. It mangles the HTML. Since it is a ClickOnce deployment, we can't register dlls (I think, correct me if I am wrong). Therefore CDO and COM is out (again, I may be wrong.... I would be happy to be proven so).
What Im making is like a face book and tagged login from my app
1. I have Combobox with 3 urls in there ( Facebook.com Tagged.com and Bebo.com )
2. I have a Form2 with webbrowser
3. I have a Button when clicked it should open up my form 2 and preview of the website which I selected in my combobox in form1
All I'm trying to do is when I select lets say facebook in my form 1 and click load it should open up my form 2 with facebook website in it.[code]Now when I click my button in form 1 it will load Form2 ( named Explorer1) but my form2 is not showing me facebook or tagged page for some reason
