This may help explain it - at the bottom of the page it talks about what to do if there is a library conflict

Check your settings in the project->settings->general-> using mfc (pick static or shared) change it to one if it is not set and you are using MFC.

The whole project is attached.
Could someone help me to check???
Thanks a lot!

remove the ignore library: LIBCMT

If I do that, I get two errors in link time:
MAIN.OBJ : error LNK2001: unresolved external symbol __beginthread
MAIN.OBJ : error LNK2001: unresolved external symbol __endthread
What shall I do?
Thanks!

You are mixing CRT's. The debug version of the CRT starts with 'debug' in the IDE


named wise it will contain a d

msvcrt.lib
msvcrtd.lib etc.

Project settings->c++->code generation->[use runtime library]

for you debug build either:

debug multithreaded
debug multithreaded dll

for your release build either:

multithreaded
multithreaded dll
