VS 2010 Convert Integer To 2-digit HEX String?
Jun 22, 2010I'm trying to convert an integer (0 to 255) into a 2-value hex string. For instance, if the integer was 255, the hex string would be "ff", if the integer was 15, the hex string would be "0f". The issue I'm having is trying to keep the leading 0. I've been able to overcome this by using an if statement to determine if the length is less than 2, in which I would concatenate a 0, but this is pretty inefficient I think. Here's my
Dim get_integer as Integer = TextBox1.Text Dim hex_value As String = Convert.ToString(get_integer, 16)
If hex_value.Length < 2 Then
hex_value = String.Concat(0, hex_value)
End If
how to improve this? I really would like to get away from using the if statement.

VS 2010 Convert String To Single (Fontsize)?
Jan 28, 2011I have a combobox which I want to use to change the font-size of text, but I'm getting an error.

Convert A String Containing A Binary, Octal And Hex Number Into A Decimal String?
Jun 7, 2009I'd like to convert a string which contains a decimal number into string that contains the binary value, the octal and the hexadecimal value of that decimal number.Afterwards I also like to convert a string containing a binary, octal and hexd. number into a decimal string.Basically I'm looking for the functions:

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
