Visual Studio Error List is hidden

I am using Visual studio 2008 and for some reason when I started today my code is not compiling. I am getting the standard 'Build Failed' message but the Error List is not showing. when I select Error List from the View menu nothing happens.

The output window shows up fine and so does the to do window.

Has anyone seen this before?

How do I show the error list in Visual Studio?

To display the Error List, choose View > Error List, or press Ctrl+\+E.

Why is my Vscode not showing errors?

This is because the C/C++ IntelliSense, debugging, and code browsing extension does not know about the current project. Navigate to View | Command Palette, enter and select C/C++ Build and debug active file: Select Project, and then select the correct project that you want to work with.
