Visual Basic 2010 - Unhandled Exceptions, Please Help

[VBbbq]

example code with issue:


If inputidval.Text <> "" And inputid.Checked Then
On Error Resume Next
WebBrowser1.Document.GetElementById(inputidval.Text).SetAttribute("Value", inputidnew.Text)
End If
End Sub


when the user puts in a name thats not valid, it would return errors
if the name they put in wasnt available in webbrowser1.document

not sure how to resolve it other than the on error resume next thing, it
worked, is there a better solution?

im not sure how to write the io.file.exists statement for
WebBrowser1.Document.GetElementById(inputidval.Text).SetAttribute("Value", inputidnew.Text)

sounds hard.. :/

heres a working snippet / example app code


Dim CodeElements As HtmlElementCollection = WebBrowser1.Document.All
For Each codeElement As HtmlElement In CodeElements
Dim code2Element As String = codeElement.GetAttribute("src").ToString
If code2Element <> "" And codeid.Checked Then
txtID.Text += "HTML SOURCE: "
txtID.Text += code2Element
txtID.Text += vbCrLf
numElement += 1
txtElements.Text = numElement
End If


if it helps / request for code

thanks for responding.
