Edward ,

I think that is want i am doing below is my other posting that knowone has 
replyed yet.
"VS2005 threads with clr option not working"
hello,

I am trying to compile a simple proragm with the thread headers included and 
the clr option in VS2005

When i include the thread headers and set the to compile with the /clr 
option the app will not execute and give the error below:
"The application failed to initialize properly (0xc000007b). Click on OK to 
terminate the application."

this sample program works fine without the clr option, however I am writing 
a managed c++ app that needs this option on.

also I have used the lib installer from 
http://www.boost-consulting.com/products/free
the 1.34.1 installer for vs8.0, I have selected all options and still does 
not work.

I have tried defining BOOST_THREAD_USE_DLL and BOOST_THREAD_USE_LIB, still 
fails.
BOOST_THREAD_USE_LIB error message is the same as if I did not have this 
define.
BOOST_THREAD_USE_DLL error message: "This application has failed to start 
because boost_threads-vc80-mt-gd-1_34_1.dll was not found. Re-Installing the 
application may fix this problem."

my project prefs have the following settings:
c/c++ - additional include directories= "C:\Program 
Files\Boost\boost_1_34_1\"
linker - additional include directories=  "C:\Program 
Files\Boost\boost_1_34_1\lib"

[code]
#include "stdafx.h"
#include <iostream>
#include <boost/timer.hpp>
//#define BOOST_THREAD_USE_DLL
//#define BOOST_THREAD_USE_LIB
#include <boost/thread/thread.hpp>
#include <boost/thread/xtime.hpp>
int main(int argc, char* argv[])
{
boost::xtime expiration;
boost::timer the_timer; //starts the timer
std::cout<<"Welcome to the sample program!"<<std::endl;

for(int i = 0;i <1000000; i++)
{
 if(i%100000 == 0)
 {
  std::cout<<".";
  boost::xtime_get(&expiration, boost::TIME_UTC);
  expiration.nsec +=int(5 * 1e08);// half second;
  boost::thread::sleep(expiration);
 }
}

std::cout<<std::endl<<"This program has been running for: "<< 
the_timer.elapsed() <<" second(s)." << std::endl;
std::cout<< std::endl<<"Press any key then enter to exit. "<< std::endl;
char buff[100];
std::cin>>buff;
}
