Visual Studio 2008: Need help finding the custom build step batch file

While building a Visual Studio 2008 project some it says "Performing Custom Build Step" and fails in that step due to some error. I can't find what batch script has been configured开发者_开发技巧 as a custom build step. As explained in http://msdn.microsoft.com/en-us/library/dd293663.aspx I searched for in the .vcproj xml file but can't find any. Neither can I find any value specified in Project Properties->Configuration Properties->Build Events->Pre-Build Event->Command Line. Please assist how to find where is that batch script specified.
