<p>I have a few batch files I need to run frequently in developing a certain project. I'd like to create a Visual Studio toolbar called "MyProject" and have commands underneath to execute these batch files. What is the easiest way to accomplish this?</p>

In the
Tools...
menu, select
External Tools...
and add references to the batch files. Then right-click on a toolbar, select
Customize...
, go to the
Toolbars
tab, click on
New...
, name your new toolbar, click on
OK
, go to the
Commands
tab, select the
Tools
category and drag-drop the appropriate
External Command
Command onto your custom tool bar.
If you need to run batch files that always run right before or after a build, you're probably better off making use of
build events
.
