COM Library Question

[Steve]

MS-VS
C#

I've added System, Microsoft.Office.Core and PowerPoint
Object Libraries to my project. I can see them
under "References" however with the libraries loaded:

PowerPoint.Application pptApp = new PowerPoint.Application
();

//This DOES NOT cause compiler error
pptApp.Visible =
Microsoft.Office.Core.MsoTriState.msoFalse;

//This DOES cause compiler error
pptApp.Visible = MsoTriState.msoFalse;

I tried deleting the references and recreating them again,
no luck. Why?

Add this line at the top of your code:

using Microsoft.Office.Core;

Thank You and that will work but the question is why do I
have to add it at all if I've added Microsoft.Office.Core
it to the VS environment references. I just wonder if
something else is wrong....

Nothing is wrong. You added the reference correctly, but unless you use the
using directive you have to spell out the namespace in full.

It just that I added Word, Excel, PowerPoint Com libraries to create
objects (i.e. Word.Open(...)), yet I don't have to state using Word,
using Excel, using PowerPoint.

Anyways, thank you - steve
