I'm a noob to VB.NET and I was wondering how to make something you type into a textbox on the application type that text into a website textbox and submit whats in the textbox by pressing a button? I am using visual studio 2008.
That is a little tricky to do, but it is possible. However, without more details on the specific browser or what you are trying to copy over, you aren't going to get a lot of answers on here.
Better Suggestion: Have you considered instead of trying to control the browser via "voodoo", that you might just have your VB.NET application submit the form/request directly to the web server and cut out the middle-man (the browser)?
I'm assuming you're trying to POST data to a web form from some other application. Check this out; it's in C# but you can translate it to VB.NET. It uses a WebBrowser control and the SetAttribute method to set input values on the web form.
// C#
WebBrowser browser;
...
browser.Document.GetElementById("username").SetAttribute("value", "MyUsername");
...
form.InvokeMember("submit");

How can I submit error reports to the developer (me) when coding in VB.NET?
I have made a Google Forms response form here. Is it possible to use the WebBrowser Control functions to paste a string into the TextBox in there and then click the button to submit it, all automatically?
Would it be better to use a different submission form service than this? I know that it uses complicated JavaScript to code everything. If it would be better to use a custom HTML website, how would you interact with that (I can probably figure out how to code the HTML itself)?
All help welcome!
OK, this was my solution: use System.Net.Mail and MailMessage and SMTP Credentials to send an email to the developer.
I am opening a web site in a vb.net 2008 webbrowser control. I want when I open the 3rd page of the web site then after the page is loaded , control focus programmatic-ly by Triggering TAB keypresses automatically by my code . Please tell me the solution to shift the focus control ?
I don't know if I have understood your question right, but you could try the following,
Keep track of whether you are on the third page in your web-browser control. If you are, you can execute a JavaScript function, which changes the focus of the text-fields.
Page.ClientScript.RegisteredStartUpScript(GetTypeOf(), "function_change_tabs", script, True)
I have a website where I am filling form data through VB.Net 2010 through WebBrowser control.
I am able to set value for input:text, input:password, checkbox, select and able to submit form.
But I am not able to select input:file programmatically. I am also able to open
"Choose a File" Dialog.
How can I send file name to select and press OK button from VB.Net Code?
I am pretty sure this is a browser security feature to prevent malicious web-sites from auto-uploading random files from the user's website to themselves. Consider how dangerous it would be if any website could pull arbitrary files off the user's computer without any explicit action from the user.
Your best bet is probably going to be dumping the Web Browser control since it will limit you to its security model. Instead consider directly getting the web page and posting a response within your application.
The following .NET namespaces should come in handy for that:
System.Net.HTTPWebRequest
System.Net.TTPWebResponse

Perhaps here are some answers for you(first post attachment):
Manipulate/Change/Form Fill data in webpages using the Webbrowser control
In terms of IE's API, you can get the select text by getting the selection object via IHTMLDocument2::Selection the property, then create a range object via IHTMLSelectionObject::createRange. If the return range's type property is "Text", you can then query IHTMLTxtRange from it and get the selected text via IHTMLTxtRange::text.
It is unclear which webbrowser control you are referring to. There are 3 webbrowser controls in the .Net Framework, one in Windows Forms, one in WPF, and one in Silverlight. Anyway, you can call InvokeScript or use the unmanaged interface like csexwb's GetSelectedText, if one of the method is supported by your control library.
Next time mention which control library you are using when you ask the question. Merely mentioning the language you choose isn't enough to resolve the ambiguity in class names.
