[RESOLVED] Read Part of an HTML Link and InvokeMember-Click

I would like to invoke a click on a link from a link that is generated by an HTML query. I am attempting to program an application that queries a website and am getting hung up where I download the .csv that is loaded by the website. Here is the link I am trying to read:

HTML Code:

---

<a href="http://www5.statcan.gc.ca/cansim/results/cansim9170974256855749928.csv">Download file from CANSIM (CSV Version, 5<abbr title="kilobyte">kb</abbr>)</a>

---

cansim9170974256855749928 from the url is not static and I don't know how to work around this. Is there a way to enable a clicking event on a random csv link? I have mashed together some failing attempts at this off and on for some time now and am now in your hands. All I have for code to show after all attempts is:

Code:

---

With WebBrowser1.Document

End With

Loop through WebBrowser1.Document.Links (each link is a HTMLAnchorElement) looking for the link with innerText starting with "Download file from CANSIM (CSV Version". Call the Click method on that link.

Is your program written in VBScript or VBA?

Hi His Nibbs and thank you for the response. I will give that a go and hopefully all goes well. I am writing this with regular ol VB.NET. I posted in this forum because of the topic matter.

Ok so I have tried playing around with your suggestion but I'm not sure how to structure this. I have:

Code:

---

Imports System.Windows.Forms.LinkLabel

---

and then in the Class Form1 I have:

Code:

---

Dim lnk As Link
For Each lnk In WebBrowser1.Document.Links
  If WebBrowser1.Document.GetElementById(lnk.ToString).InnerText = "Download file from CANSIM (CSV Version, 5kb)" Then

  End If
Next

---

However this throws an error at run time saying "Unable to cast object of type 'System.Windows.Forms.HtmlElement' to type 'Link'."

I will keep tossing around some thoughts while I work on this but I am still stuck.

After some digging around on the interwebs I found the following but it doesn't find the innerText value of the link

Code:

---

For Each link As HtmlElement In WebBrowser1.Document.Links
  If link.InnerText = "Download file from CANSIM (CSV Version, 5kb)" Then
      WebBrowser1.Document.GetElementById(link.InnerText).InvokeMember("click")
  End If
Next

---

Woot, this is finally behind me now. Thanks for the kick in the right direction His Nibbs, I have the following code which does the job nicely

Code:

---

For Each link As HtmlElement In WebBrowser1.Document.Links
  If link.InnerText.Contains("Download file from CANSIM") Then
      WebBrowser1.Navigate(link.GetAttribute("href"))
  End If
Next

You posted in the wrong forum then. The forums are arranged by programming language, not topic. But you got there in the end.
