Not able to add tables to data diagram. Every menu option under database diagram menu are disable.

Hi there,

Can you provide a lot more detail? For example, where does this happen? In Visual Studio or in SQL Server Management Studio? Which versions of these programs are you using? What's the connection string you are using for that database / how do you connect to it?

Without that, it's impossible to tell what's going on.

Cheers,

Imar

Hi there,

Can you also answer the other questions I asked? I currently don't have a clue where this is happening, or what steps you're taken.

Cheers,

Imar

Hi Imar, don't worry about this. It seems to be only happening in Windows 7. I setup a Windows Vista machine and I no longer have the problem.

Probably also that the Windows 7 machine is on a LAN. I can no plug away.

Thanks for responding.
