In Visual Studio 2008, I am not able to see the Batch Build option for VB.NET projects (as for C++ projects).
I am new to VB.NET, but does it have other options to do a batch build rather than creating a batch file?
To make the button appear (written from a Visual Studio 2005 perspective, but probably the same or at least very similar for Visual Studio 2008):
Right click on somewhere on the Visual Studio toolbar and select Customize..., then on the Commands tab in the Categories list, select Build.
You should now have a list of Build commands in the Commands list, one of which should be Batch Build.... Drag and drop that to somewhere on the toolbar.
However, I'm not certain if batch builds are supported for Visual Basic, so I'm not sure if this will help you.
