Hi guys I am have some issues with a code. The code is retreving a peice of code from a web site

I am using the code to retrive the output

Code: Select all

textbox.text = WebBrowser2.Document.GetElementById("OutputHistory").InnerHtml

site code

Code: Select all

 <td width="25%">
            <select size="4" name="OutputHistory" id="OutputHistory" style="height:300px;width:100%;">
	<option value=""></option>
	<option value=""></option>
	<option value=""></option>
	<option value=""></option>
	<option value="">C0</option>
	<option value=""></option>
	<option value=""></option>
	<option value=""></option>
	<option selected="selected" value="A1">A1</option>

now i want to retreve just the C0 in the code to a text box in visual
now the problem os that the C0 can be diferent things like a,b,c,d,e,f and tose are from 1 to 20

It would be nice if the text box actuly only showed the selected one in this example the textbox.text would be equal to A1

Try this code:

Code: Select all

Dim outputhistory As HtmlElement = WebBrowser1.Document.GetElementById("OutputHistory")
        Dim optionList As HtmlElementCollection = outputhistory.GetElementsByTagName("option")
        TextBox1.Text = optionList(8).InnerText

This will get the text in the 9th <option> tag (in this case, A1). However, if you want to get C0, use this:

Code: Select all

Dim outputhistory As HtmlElement = WebBrowser1.Document.GetElementById("OutputHistory")
        Dim optionList As HtmlElementCollection = outputhistory.GetElementsByTagName("option")
        TextBox1.Text = optionList(4).InnerText

Sorry, I don't understand what you mean by that. The first bit of code I gave you will return the value of the selected item, as long as there are 9 <option> tags and that the selected one is last.

Do you mean the number of tags will vary?

You can add this code so it gets the selected text:

Code: Select all

        Dim strIndex As String = outputhistory.GetAttribute("selectedIndex")
        Dim index As Integer = Integer.Parse(strIndex)

        Dim selectedText As String = optionList(index).InnerText
        TextBox1.Text = selectedText
