MS2008 linking problem vc++

Question

HI I am using boost library(1.40) genrated files, that files generated while boost installation variant option are (multithread, static runtime)& VS2008. i try to call a mongodb server by simple client program
---------------------------------simple connect code ------------------
#include <iostream>
#include "C:\\data\\db\\include\\mongo\\client\\dbclient.h"

#pragma comment( lib, "mongoclient.lib" )
using namespace mongo;

void run() {
DBClientConnection c;
// c.connect("local");
}

int main() {
try {
run();
cout << "connected ok" << endl;
} catch( DBException &e ) {
cout << "caught " << e.what() << endl;
}
return 0;
}

-----------------------------------code end -------------------
i also provide library and include path in visual studio ->tools->option->vc directory->library & include

but it display me this error list. if i remove lib path from tools->option then it demand me the list of lib files are :
1.libboost_date_time-vc90-mt-1_40.lib
2.libboost_filesystem-vc90-mt-1_40.lib
3.libboost_system-vc90-mt-1_40.lib
4.libboost_thread-vc90-mt-1_40.lib
5.libboost_program_options-vc90-mt-1_40.lib

but if path is right then it display this linking error :

Hi Chetan,

Are you sure that you have include correct Header file(.h) to project? dbclient.h but not mongoclient.h? And use the correct namespace?
