Don't know where to place subroutines getting invalid namespace

I'm not sure where to physically place my subroutines in vb.net I get
namespace and not declared errors...

Error messages? Make sure, refereces to the components needed by your
application are set and namespaces are imported. You can find out in
what namespace a certain class resides by using the object browser (F2).

Stop??

=)

Not the "best" position especially when you have calls following it...

What are you stopping?

Hi X,

I think that the only problem with your code is that you did not set a
reference to the system.management.namespace as you already told.

You do that by clicking on

Project->Add Reference->System.management than select and ok

There are two little errors in your code, you do create the inParms and the
outParms, however I think you see that yourself because after setting this
reference those are the only errors that stay.

Nice using that stop method, I think I can use that as well before a catch,
I do that now in a little bit dummy way.

I hope this helps?

(When you do not see the answer on those two little errors reply than?)

I used to have the subroutines in that private sub.. There was only one
stop,... Must have been a typo

I added the references and moved the subroutines as suggested. Thanks!

The key gets created, but unfortuanately the second subroutine is supposed
to create a value and it doesn't return an error or create a value..
outParams("returnValue") comes back as a 6... not sure what that means. Here
is the working code.

Are they any other values I can "catch" to help me figure out wjy I'm not
seeing a value ?



I am going to try to read a value next and see if that works.
