C# - Converting A HtmlElement Into An Image?
Jul 10, 2009I'm using a WebBrowser control in VB.Net to load a website. At that point, the WebBrowser.Document.Images property returns a collection of HtmlElement that are considered images.
What I'm trying to do at this point, is take a particular HtmlElement that represents an image and turn it into a System.Drawing.Image so that I can manipulate it. But I can't figure out how.
I did try to search for an answer, but came up with nothing. 'WebBrowser', as it turns out, seems to be a really popular keyword.
EDIT: It's been suggested that I use the SRC attribute of the HtmlElement to download the image; but the image can be dynamic - meaning the image I download can be separate from the image on the website....so, that won't work for my purposes.
Converting HtmlElement To HtmlControl?
Jul 25, 2009It seems that in previous versions of Visual Basic it was possible to convert a System.Windows.Forms.HtmlElement to the various System.Web.UI.HtmlControls but in 2008 I cannot seem to do this.What I am trying to do is convert HtmlElements that I got from a WebBrowser.Document into HtmlTableRow HtmlAnchor etc. to manipulate them but I cannot find a way to convert them in this version. I guess my questions are :1. Is it possible to convert a System.Windows.Forms.HtmlElement into one of the various ystem.Web.UI.HtmlControls ?2. If not, is there another way to cleanly manipulate tables and anchors etc. from a HtmlDocument without writing my own logic to find the tags etc

VS 2008 Get An HtmlElement From WebBrowser
May 17, 2009I am having some problems with Navigating to the same URL of the WebBrowser.I am trying to get an HtmlElement from the WebBrowser. This HtmlElement is a simple link ("href"). The link is shown on the site that I am navigating to, every hour for only 1 minute and than disappears.I want to check every 15 seconds if this link exists. So, I am doing a loop with a Timer and refresh the WB control.The problem that I encounter is when the WB control already navigated to the site that I wanted to check, it always navigate to the same page when refreshing. The links or the DocumentText are never changed, even if I enter Internet Explorer and see that it has been a change in the page.

Webbrowser Get Htmlelement Position
Apr 26, 2012I am trying to get position of html elements in a .net's webbrowser control and failing, i need the exact position of the element relative to the whole document or the webbrowser control to be able to send a mouse click using SendMessage() P/Invoke..I have tried the solution from here but it didn't work:getting absolute position of HTML element in webbrowser control with C#.I am guessing that is because the page relies on very complex ajax and css.the function "WebBrowser1.Document.GetElementFromPoint()" works just fine in getting the accurate html element, i just need the opposite of it.other wise, should i just keep on searching using "GetElementFromPoint()" until getting the correct element?

Why Won't HtmlElement.SetAttribute Work
Dec 29, 2011I'm trying to post to my blog programatically using VB .NET. So far, I've been using this to set the title:
WebBrowser1.Document.GetElementById("entry_title").InnerText = "title"
It works fine. However, when I try to set the body text:
WebBrowser1.Document.GetElementById("entryBody").SetAttribute("value", "body")
It won't work. It worked for me before, but now I can't get it to work again. I used the .OuterHtml command to view the line of code, and it assigned the value perfectly. However, it still won't display in the webbrowser. This is the code from the webpage I'm working with:
<textarea style="width: 95%; height: 350px;" name="entry[body]" id="entryBody">text inserted here

Screen Coordinates Of Webbrowser HtmlElement?
Jul 3, 2009I am working on a project that involves the editing of html of pages on the fly. I have put a webbrowser on the form, and I am able to retrieve the element under my mouse by using: wBrowser.Document.GetElementFromPoint(e.ClientMousePosition) in the Document.MouseClick event.However, I want the experience to be more intuitive, by placing a semi-transparent blue rectangle over whichever HtmlElement the mouse is currently hovering over. I created a borderless form with 20% opacity for this, which works great, except that I cannot for the life of me figure out how to calculate the screen coordinates of the element under my mouse. Here is what I have so far, but while the size is adjusted correctly, the location of the rectangle is just stuck at (0, 0) relative to my form. Highly annoying:

View 3 RepliesEvaluates Loop Condition In Do...Loop Statment To Determine Whether Loop Instructions Should Be Processed
Mar 14, 2011Makes the following statement about the code below:
**"The computer evaluates the loop condition in the Do...Loop statment to determine whether the loop instructions should be processed. In this case, the inputsales <> String.Empty condition compares the contenst of the input sales variable to the String.Empty value. As you know the String.Empty value represents a zero length, or empty, string if the inputsales variable is empty, the loop condition evaluates to True and the computer process the loop instructions. *If on the other hand the inputsales variable is not empty, the loop condition evaluates to false and the computer skips over the loop instructions.
Based on the code I think it is the opposite: ...that while the inputsales value is not empty it should evaluate to true and process the loop and if it is empty it should evaluate to false and skip the loop?
See below.

HtmlElement From A WebBrowser Object Strips Double Quotes From HTML?
Mar 1, 2010I am grabbing an HTMLElement from a browser object and then using getElementById to grab the element I want. When the element is grabbed into the HtmlElement object double quotes around attributes like <input type="checkbox" name="test1" /> becomes <input type=checkbox name=test1>.It is removing the double quotes and backslash from the HTML available in the HtmlElement. Is there anyway to get the HTML element from Visual Basic .NET code and keep the true HTML formatting?

I know about AdWords API and client libraries. I have been investigating them for some time and they are not so easy to use.

Automate A Button Click?
Jul 12, 2008Working with dynamic button. So if i have 5 buttons created dynamicly, i can get alot of information from the button click of that button. You click a button on this app, it will show the name of the button.
But now I want, lets say button 4 to click at 4:45 pm today. Normally I would do something like compare a string to "4:45", and when true, then button 4.Perform_Click.
But button 4 is dynamic, so how do I call that button in my code. How can I address it. I know it will be there when the program is running, I just don't know how to get to it in code.
Now I do have the button names in a database, so I can get the name that I want from there. Just not sure how to tell it, "Do a perform click on button 4" The code below is my test bed, so If you click the main button, it will create a button, and a timer. Click the button that was created, and it will show the button name.
