Interop vs. Core [Not Resolved]

[kleinma]

I was just re-reading some of the posts to make sure I didnt miss something and I did but it doesnt make sense.
"Imports Microsoft.Office.Interop.Outlook" make it work but at the office my system is using the "Imports Microsoft.Office.Interop"
only and that works?

Why is it different and why doesnt it recognise from just the Interop import the Outlook namespace?

well there are 2 different COM references, one is the Office 11.0 object library and one is the outlook 11.0 one.....

I think if you reference the first one, it gives you what you say you have at work... while the second give you what I had posted..

Well now I'm even more confused. I added a reference to MS Excel and with the Imports ...Interop only I can
do Dim oWB As Excel.Workbook without errors. I should be able to do the same for Outlook but it doesnt have the PIAs I guess.

do you see the outlook PIA in the GAC?

But if you add just the Outlook reference then it adds both the Outlook and Office references.

I'll look in the GAC.

its weird... if i remove the office reference but leave the outlook one, it still works.. did this to test

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Dim OL As New Microsoft.Office.Interop.Outlook.ApplicationClass
        MsgBox(OL.Version)
        OL = Nothing
    End Sub

im not sure if you lose any other functionality though...

I dont see the PIAs I re-ran the Office setup and double checked if the .NET Programmability were installed
for all products and they were. Should I install the PIA Redistributables download too?

hmmm maybe.. or can you select an uninstall of the PIAs in the office setup, and then try to install them again?

Ok, I removed the Outlook PIA and re-opened my Outlook project. Removed the reference and re-added it.
It works now but then that means I dont have PIAs for Outlook. It worked the other way (with PIA) but I'll have to
connect to work and compare the GAC? (I'm playing hooky from work today )

I don't know what that office one does. I remember that I added it, removed it, added it again, etc. Never did see any changes.

The Office reference is the core of the Office program. Like commandbars, toolbars, buttons, and menu items.
