I need to know how to control an object inside a frame on a web page. Actually, all I need to do is to be able to change the innerHTML of the body of the frame. The frame's id is "content_ifr". I've tried using the "getElementByID" method of the document to get the frame, and then setting that frame's document's body's innerHTML, but it didn't work.

What I'm trying to do is load a URL and grab the text from it.The text on the file I'm using is simply a 1, that's all. However, when the messagebox shows, it's empty. I've tried using google.com as the URL and got the same response, so that means it's somewhere in my code here.
I am currently working on some software for a taxi company, and we have been asked to create a webbrowser (only simple) for the users which we allow to use it, to view traffic updates from a website that we already know about.
But...

Basically we don't want them to be able to surf the net at all, only be able to work!
I have VS 2008 and am working in VB.Net forms.I have a webbrowser control where I am trying to control input fields that are dynamically created. If a text field has proper handles such as id and name tags there aren't any problems.
For example, I am trying to work with twitter for posts. I know twitter has an API but I want to work with many similar systems and want to avoid the API as its case specific and I want to scale things within the VB.Net form. The login fields for twitter are easily handled, however the posting field once your logged in is just a text area with a class. There is a tagname but I have been unable to post using the tagname element.Any examples of posting to twitter without the API ?
web1.Document.GetElementById ... ?
web1.Document.GetElementsByTagName ... ?
I've done extensive searching but can find nothing to make it happen. DOM inspectors havn't revealed much about the field.
We've been asked to make a program based on a spec where we enter some details and it will then output a graph.Part of the assignment asks us to set up a timer so that the bar chart will display each bar seperately with a time delay between each one.However the timer is assigned to a form (Form2) while the draw commands are within another class called Expenditure.
While the specification doesn't specifically say we should stop the timer from within the class it is implied.Now I have tried Form2.Timer1.Stop() and Form2.Timer1.Enabled = False within the class without any luck.I'm wondering is it possible for the Expenditure class to stop the timer or does it need to be done within Form2?

When it comes to the second variation of the code I often get the following error message (exception):NullReferenceException was unhandled Object reference not set to an instance of an object.
Basically - how do I tell it to click on it only if there are two separate and unique strings of html code in a html tag?
I have 3 msgboxes in my program which should appear sequentially. However, sometimes they appear sequentially and at other times they appear randomly.

Which I do not want. I simply want the tabs to be activate in a flow...
