Registry Help - Should be dead easy

[Musician]

I'll give you my custom function for creating file associations. You should be able to figure it from that:-

Public Function AddAssociation(ByVal fExt As String, ByVal appName As String, ByVal appPath As String) As Boolean 
  Try 
       Dim extKey As RegistryKey = Registry.ClassesRoot.CreateSubKey(fExt) 
       extKey.SetValue("", appName) 
       Dim appKey As RegistryKey = Registry.ClassesRoot.CreateSubKey(appName) 
       appKey.SetValue("", appName & " File") 
       Dim shellKey As RegistryKey = appKey.CreateSubKey("shell") 
       Dim openKey As RegistryKey = shellKey.CreateSubKey("open") 
       Dim commKey As RegistryKey = openKey.CreateSubKey("command") 
       commKey.SetValue("", appPath & " %1") 
       Return true 
   Catch 
       Return False 
   End Try 
End Function
