Visual Studio 2010 projects are never up to date -

i've nail issue of projects in our visual studio 2010 solution. when build never date , rebuild.

using post

http://blogs.msdn.com/b/vsproject/archive/2009/07/21/enable-c-project-system-logging.aspx

i able figure out of projects had headers listed no longer existed. removing these references fixed 5 of projects.

but leaves 13 beingness built. reason vs2010 log is

devenv.exe information: 0 : project 'c:\path\to\project.vcxproj' date check disabled because lastbuildstate and/or lastbuildunsuccessful properties not set.

when search google i'm getting hits message. no solutions.

does know whats going on?

all these projects nmake based. kinda suspect may root cause. nmake projects set these properties?
