I do not know how to communicate form VB.net with a webpage, meaning that when I send a data string, then the results shown on the form VB.net, so the webpage of the server sends the data string to form vb.net.

i have an aspx page with vb.net back end. in that page i get names and url's from the database depending on different conditions. My requirement is that when i get the url, the code should then use that url and have that webpage in a small preview form on my existing aspx page. so basically i have a table as follows -
[Code]...
I am having a issue when navigating to a URL that requires the user to log-in before proceeding. The system we are logging into takes care of going to the log-in page and then back to the page I specified. But when I navigate (webbrowser.navigate = ...) to the web page it locks up the form until the method is complete. But I want to wait in that method until after the user logs in and then the window is redirected, and I want to make sure they got there. I am going to need to do this multiple times during the program. Is there another method I should use? I would prefer to use the embedded web window in VB2005.
View 3 RepliesI have a problem I am trying to solve in an elegant manner. I have a .net application that I have created. I am trying to get one of the forms to be shown from a webpage. This sounds strange I'll admit, so here is the backstory
We have some large monitors at work, that show information on them. I have no control over how the information is displayed. Currently they are just using a browser and tabbing in the browser to show each different piece of information on the screen. Most of the info they show is just standard html stuff, text and images.
Now along comes my winforms application. The part of the application I need to show is a graphical display. Everything on this display is drawn using GDI+, if that matters. I need to get this form into a format that I can show. Below is my own solution, but I am pretty sure this is not the best method, but it may be the only method I can use[code]...
I though about doing something with the clients, however the clients are not always up, so I could have periods where the image wouldnt be updated.
I also was thinking about an ASP.net solution, but that would require me to learn ASP.net, and I am not quite ready to take that challenge
I am new to vb.net (2010) and am working on a project that has to send information from a client application form to a php-based web page.

One section of my latest project idea involves linking several form controls to the Google map (distance calculating section), which is area I'm not familiar with.
What I would like to achieve is following: (VB2010) I would like to link two combo boxes on my form to Google map (Start Address and End Address)as well as two labels representing distance & ETA time to Google map (Suggested route, option No.1, highlighted section).
As soon as user select values from combo drop downs on my form, code performs search trough Google web page and return values to my labels on a form. At the same time database would be populated with a same search values (Start Address, End Address, Distance in Km and ETA time)
Link to a web page seems to be a very common request within community members but I did not find anything similar to what I would like to do, so it makes me think that my project idea is going to be" hard bone". I do not need Google web page displayed on my form in a split container or in any other way.

View 5 RepliesI have written an application that lets me track work crews as they move from one job site to another. It runs on my local computer as a windows form. The form displays labels with the job site and crew names on them. The application is written using VB.net 2003. What I would like to do is see what is displayed on that form from another computer in a different office. Is there a way that I can use a web page to display what is on the windows form?

View 6 RepliesI have a list of data which needs to be inputted into many different fields on a webpage. usually about 1000 or so and i am trying to automate this using vb.net but i couldn't find a better solution than using appactivate and sendkeys. this solution definitely isn't very accurate and reliable.
is there another, better way of accomplishing this?is there a way to find certain input fields on a webpage, set focus to it and input data in a more reliable way? the way i have it written at the moment is appactivate and tab to certain fields and input data using sendkeys.
I was trying to find examples of how one would make a webpage using asp so that I could have the visitor enter information on a form and then when they hit submit it will be attached to my webpage indefintaly and any visitor can view it.
View 4 RepliesWas trying to make a little project which will login to a site. The problem i am facing is with the captcha code display..
Was searching around to get the captcha to the form directly but didn't found anything useful.
So my question is how to display only the area of the captcha on the form instead of the complete form.
Like suppose I want to display only the portion where the logo of Visual Basic .NET Forums - The Exclusive VB.NET Community is located instead of complete webpage.

What I am wanting to do is create a program that will load up a page (it is password protected) and get the links out of any files that I need to download. The green text is the text that contains the link and will be repeated for every file.One little thing is that there are multiple pages that are accessed through JavaScript with the code highlighted in red. So, I also need to step through the pages and get a list of all files on subsequent pages.
Everytime I run this program, it will get a list of all files and only download the ones that aren't already downloaded. However, I have never done this before and was wondering what I need.I have accessed the source of pages and parsed it for things like links before, but not sure if that is the optimal way or if there is some other way to handle this particular situation easier, especially since I have multiple pages to deal with and JavaScript.
I am making this program that has a loop that goes to a website and fills in a form within the loop. But first, here is my code thus far
Dim message As String = TextBox3.Text
Dim loopnumber As Integer = TextBox4.Text 'makes the necessary variables
Dim browser As New WebBrowser
Dim url As String
[Code] .....
But what happens is that the loop runs a few times then it errors on the setattribute line (line 19 above) with
NullRefrenceException was unhandled
And I have a feeling that it is not loading the page fully before it tries to fill in the form.
I tried several samples on the forums I can not get it to click.

How would I send that to a remote server as if I had just filled out a form on a webpage? Specifically... I'm looking to have a program automatically log me in to a web site like Facebook, get important details/updates, then log out.
I have implemented webbrowser control in my windows application. I have some functions inthe class file. i want to use those functions from the webpage which is displayed in my windows app through webbrowser control..For example say... I have an standalone windows software. Which has a webbrowser control in the some form. Now i would like to create a webpage that can be displayed in the webbrowser control in win app which has some buttons and textboxes. When i click on button in the webpage it should get the version number of that software. I have some other functions that are in the class file aswell.. but dont no how to call those functions from that webpage when a button is clicked or something like that.
View 4 RepliesOk so basically heres what i need to do: Extract text from the webpage that meets a certain criteria. There will be a ton of these on 1 page and i would like to add them to a rich textbox on sperate lines.
I know that it needs to be in a loop and its needs to Parse the wepage(Dim web1 As String = Me.WebBrowser1.Document.Body.InnerText)
The criteria is: Starts with 1 to 4(random) integers, Followed by "my" then 13(random) numbers and letters. Or if it starts with "167my" + 6(random) number and letters.
Edit: Also im going to try to make it loop through a list of webpages to do this.

I'm working on a little app which needs to recieve information from a script on a web server. I tried to have the vb.net app pole a php web page for a command every half of a second. This worked but, the app is streaming video and every time the app needs to pole the webpage the video stutter stops. I tried setting the pole timer to 5 seconds and still every 5 seconds the video stutters. I thought that maybe sockets would be the answer, so I looked for examples of vb.net socket servers and php socket clients. I tried implementing a solution but the php cannot seem to connect to the vb.net server. I googled around and saw that maybe php cannot communicate with a vb.net application.
