>While compiling the project (for simplicity, I just selected a "rebuild project"; all other options are unchecked), I get a message "error reading file". Not knowing which file caused this, I created a new project; the "error reading file" appeared for one particular class library, more specifically, a file called vfxform.vct (part of the Visual Extend framework). According to the help, the error message means that:

At a FoxPro conference (in Sydney), Rick Schummer mentioned a way to identify which file is causing a problem during a build. I wish I could remember how he did it! Something to do with the debugger I think.

Anyone know how to identify the problem file during a build?
