VS2008: Disable asking whether to reload files changed outside the IDE

Question

I have a Visual Studio 2008 project where some code files are generated with each build (a parser, integrated via MSBuild aka editing the *.csproj file). VS does not know about the generated nature of these files (i.e. they are not the result of a "Custom Tool). So they "change" with every build, naturally. And VS2008 asks me after every build if I would like to reload those files:

This file has been modified outside the source
Do you want to reload it?

That would be ok if I had one of those files opened and in front of me, but I get these modal dialogs even with none of the code files opened.

So my question is: Is there a way to disable this dialog, per project, per solution or globally?

Thanks!

Answer 1

For VS2008: Tools > Options > Documents > Detect when a file is changed outside the environment

For VS2010/2012/2013/2015: Tools > Options > Environment > Documents > Detect when a file is changed outside the environment

Answer 2

In Visual Studio Pro 2012

There is an "Auto-Load changes, if saved" that works.

Tools > Options > Environment > Documents > Detect when a file is changed > Auto-Load changes, if saved

Answer 3

Because a picture paints a thousand words...

Answer 4

I generate source files on every build, and I don't (normally) get a "file has been modified" message if the file is not open in the editor.

I was getting it just now, however, on a closed file. (That's why I went searching for this question.)

I think that's a bug. The file seems to get wedged sometimes. (But this is the first time it has happened in about a year.)

I think I've found a work-around just now: Open the offending file and then close it again.

The point is, you shouldn't need to turn off changed file detection.
