ISenslogon

[Leigh Webber]

Does anyone have an example of VB.Net code that uses the ISenslogon
interface? The documentation says to "subscribe to the SENS events that
interest you" and to "create a sink object". Whazza?

I want to be notified when the display has been unlocked or the ScreenSaver
has been stopped. If someone can get me started with a simple example in VB,
that would be great.

Re: ISenslogon

Thanks, CJ -- but the little details still escape me. Let's say I have a
simple Winform app with a btnStart button:

Private Sub btnStart_Click( ByVal sender As System.Object, ByVal e As
System.EventArg s) Handles btnStart.Click

'What goes in here? Let's say I want to write the current time
'to Me.txtScreenUnl ocked when the DisplayUnlock event fires.

End Sub

Re: ISenslogon

Hi Leigh,

This is actually an event sink itself (note the handles clause, which can be
used when a variable is declared WithEvents). If you look up in your
Windows Forms Designer Generated Code Region you will see btnStart is
declared

Private WithEvents btnStart as System.Windows. Forms.Button

Which allows you to use the handles clause (and intellisense works well with
it)...

but enough about that..

Private Sub btnStart_Click( ByVal sender As System.Object, ByVal e As
System.EventArg s) Handles btnStart.Click

AddHandler objContainingEv ent.DisplayUnlo ck, AddressOf MyEventHandler

End Sub


Private Sub MyEventHandler( sender as object, e as System.EventArg s)

me.txtScreenUnl ocked = Now().ToString( )


End Sub

Well, you can set a reference to the SENS Event Notification System through
the COM tab, but I looked at it and could not figure out how to use it. It
has a number of interfaces but I couldn't determine if I needed to
implement those interfaces or what.

Perhaps someone who is familiar with it could look at them and make heads
or tails out of it.

Re: ISenslogon

Thanks again, CJ. I think we're getting close. Here's my code:

[Reference added to COM: Sens Events TypeLibrary
(c:\windows\sys tem32\SENS.dll]

Public Class Form1
Inherits System.Windows. Forms.Form

[Windows Form Designer generated code]

Private Sub btnStart_Click( ByVal sender As System.Object, ByVal e As
System.EventArg s) _
Handles btnStart.Click
Dim loSENS As New SensEvents.SENS Class
AddHandler loSENS.DisplayU nlock, AddressOf MyScreenUnlocke dHandler
End Sub

Private Sub MyScreenUnlocke dHandler(ByVal UserName As String)
Me.txtScreenUnl ocked.Text = Now().ToString
End Sub
End Class


When I run the project and click the button, I get an error on the Dim
loSENS as New SensEvents.SENS Class line:

"An unhandled exception of type
'System.Runtime .InteropService s.COMException' occurred in UI.exe

Additional information: COM object with CLSID
{D597CAFE-5B9F-11D1-8DD2-00AA004ABD5E} is either not valid or not registered."

When I look in RegEdit, I see that the AppID for
c:\windows\syst em32\SENS.DLL is {D3938AB0-5B9D-11D1-8DD2-00AA004ABD5E}, while
the TypeLib value is {D597DEED-5B9F-11D1-8DD2-00AA004ABD5E}

Where does the D597CAFE part of the CLSID shown in the error message come
from? In the VB solution explorer, the SensEvents reference shows the correct
identity (D597DEED-...).

Dunno what to make of all this.

Re: ISenslogon

That certainly is interseting. I'm not too sure what to make of that. I
would say try readding the reference, but don't know if that will do any
good. It should have created the Interop to call the proper version... why
it only changed that first part is what I don't understand.

Hmm... perhaps someone else has seen this before... have you upgraded
libraries for SENS at all?

Re: ISenslogon

I haven't upgraded sens.dll, as far as I know. I don't even know how it got
on my sustem -- I suppost it came along with Internet Explorer 6, but that's
only a guess.

Perhaps someone else could copy and paste my code, try it out, and tell use
whether they get a different result? Or could anyone post some code that
actually does work?

Is this a Regular DLL or an ActiveX DLL?

Re: ISenslogon

I think it's a special kind of DLL. I have been poking around the
documentation for Loosely Coupled Events, and it looks like you subscribe to
SENS events using the Component Services snap-in. There's a C# example in the
LCE docs that I can make work, but it involves subscribing to a custom
publisher you create in code. My current stumbling block is that in Component
Services I can't find the SENS publisher to subscribe to!

Sure wish there was someone at MS who could show a sample of subscribing to
SENS events.
