Simple keyboard hook application in vb.net

Hello,

I have a requirement of triggering my application on Ctrl+d only when user is in Windows Explorer. For that I have an ahk script which works perfectly..

Code:

---

#IfWinActive ahk_class CabinetWClass
^d::
Run "C:\myapp.exe"
return
#IfWinActive  ; turn off context sensitivity

---

But I want implement the same in vb.net, While searching I came to know that this can be done using Autohotkey.dll from this site But no where I got any working dll.

How to achieve in my requirement in vb.net ?
Please help.
