Exception when adding a toolbar as a word-addin

[Matthias Langbein]

Hi all,

I tried to build a MSDN-Tip how to integrates a word-toolbar in a
addin:
(http://support.microsoft.com/Default.aspx?kbid=302901#XSLTH3228121124120121120120)

The class member applicationObject was initialized with the
word-application-objekt. When calling


Microsoft.Office.Core.Commandbar toolbar = null;
try
{
toolbar = (Microsoft.Office.Core.CommandBar)_
applicationObject.CommandBars.Add("My Toolbar",_
Microsoft.Office.Core.MsoBarPosition.msoBarFloating,_
System.Reflection.Missing.Value, true);
}
catch (Exception ee)
{
......
}


I recieve the exception:
"Der Objektverweis wurde nicht auf eine Objektinstanz festgelegt."
which means pretty much:
"The bject link was not assigned with a object instance."

How comes? I'm desparate...
THX for all the help, yours Langi

You are writing an add-in using C# and posted the question to a COM group
and 2 VB groups?

Try searching for newsgroups containing .dotnet. in the name.

microsoft.public.office.developer.com.add_ins is the correct group.
Followup-To set accordingly.

I considered that but any issues are still more likely to be C#/dotnet
related than direclty COM related. BTW, changing the subject is not usually
a good idea because it causes some newsreaders to see it as a new thread.

Hi all,
I decided to post the code, maybe someone can tell me why there is the
exception...

I get the warning:

'Microsoft.Office.Core.CommandBar' is defined in multiple places;
using definition from
'c:\WINDOWS\Microsoft.NET\Framework\v1.1.4322\office.dll'

Might this have anything to do with it? And how do I solve this
problem?

 

[- B@rney]

Yes, it has something to do with that error message.

I had the same problem. The resolution was to correct my reference to point
to the office.dll in the GAC and make sure I didn't have references to any
other versions of the office.dll
