Visual Basic.Net 2005: Can I open Internet Explorer and Windows Explorer?

Greetings all,

First off, it?s been a couple years since I did any visual basic programming, so I know I?m a bit rusty.

I?m trying to get one button on my Windows Application to call up the Adobe homepage in Internet explorer, and another button to open a folder called Documents in Windows Explorer. Both are functions I don?t think I have ever coded before, and I am having little success. Below are code examples/templates

Dim wbShow As New WebBrowser

Private Sub btnDocuments_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnSDM.Click
'''''what code should go here to call up
''''' windows explorer or something similar?
End Sub

Private Sub btnAdobe_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnAdobe.Click
____wbShow.Navigate("http://www.adobe.com")
'''''above code causes errors reguarding security,
''''' any idea how to fix or know any alternate functions?
End Sub

Any help would be greatly appreciated.
